"Welcome! Merry Christmas Eve!"

As soon as I walked in the door, a lifelike parrot standing on a shelf greeted me in old London English.

Although it looked no different from a real bird, Zuo Si still recognized with the Eye of Knowledge that it was a small gadget made by the transformation spell.

In fact, similar items, such as kettles that brew their own tea and coffee, and brooms, mops, and brushes that clean themselves, are quite common in wizards' homes and shops.

Due to the long-term peaceful environment, magic in this world has gone a long way in providing entertainment and convenience for daily life.

When Zuo Si first saw many of the small items, he would inevitably feel amazed and admire the makers' ideas and imagination.

Of course, there are also some works that pose safety risks and dangers.

Passing the parrot created by the Transfiguration Charm, the two quickly walked to a table by the window and sat down.

Soon after, a waitress in a gorgeous robe came up to us with graceful steps, put down a menu with magical effects, and said with a smile: "Just order what you want to eat. The dishes you ordered will appear on the table in no more than a minute."

"Thank you very much."

Zuo Si had already seen the way food was served at Hogwarts and understood that this was also a form of spell used in daily life. He immediately turned the menu in his hand around and handed it to Isadora.

"Here, choose whatever you like. But remember not to order any alcoholic drinks."

"OK."

The girl nodded slightly excitedly, staring with her big curious eyes at the moving and fragrant photos.

Whenever she took a fancy to a dish, she would point her finger at the price mark on it.

moment!

A steaming delicious dish appeared on the table out of nowhere.

Although Isadora had seen many spells that could be used in daily life when she was in the Mage Tower, this was the first time she had experienced something so convenient and thoughtful.

After a while, the table was filled with all kinds of delicious food.

It has to be said that compared with traditional British dark cuisine, French cuisine and Italian cuisine are obviously much better in both taste and visual effects.

Especially small desserts like panna cotta and caramel pudding, which are obviously very much in line with girly tastes.

Isadora was beaming with joy while eating. Her rosy little face was filled with surprise and happiness, which was completely different from her usual silent and taciturn appearance.

It was a rare occasion for Zuo Si to completely relax. He enjoyed the food and drinks while chatting with the girl in front of him with a smile on his face.

But this warm moment did not last long.

As a familiar figure walked in from outside, he immediately showed a surprised expression.

Because the other party was none other than Severus Snape, the Potions professor at Hogwarts.

Behind him followed an old man with white hair and beard.

Since the restaurant was not big, Snape soon noticed Zuo Si who was having a meal. He immediately stepped closer and asked in a slightly puzzled tone: "Sos, why are you here?"

"I just happened to go to the post office to deliver the Christmas presents, and brought my friends here for a quick meal." Zuo Si replied calmly.

"Ah! I forgot you didn't buy your own owl. Also, who is this?" Snape turned his gaze to the girl.

Although his eyes could scare the freshmen at Hogwarts, it had no effect on Isadora, who possessed psychic powers and was extremely precocious.

The latter even stood up and bowed gracefully, using the power of magic to introduce herself in slightly stiff English: "My name is Isadora, and I'm Soth's best friend."

"Are you a Muggle?" Snape's eyes flashed with curiosity.

"Well, yes." Isadora nodded slightly.

Since she had heard Zuo Si's general explanation of the situation in this world on the way here, she understood what the word "Muggle" meant, and she also had no intention of showing her psychic powers and magical powers to these strangers.

"interesting……"

Snape didn't know what he was thinking of, and the corners of his mouth curled up slightly to reveal a playful smile.

Zuo Si ignored the other party's meaningful expression and asked directly: "Professor, shouldn't you be staying in Hogwarts Castle preparing for Christmas? Why did you come to Diagon Alley?"

"I'm here to help you buy the things on your list." Snape rolled his eyes in annoyance, then pointed at the old man behind him. "This is the owner of the Hog's Head Inn in Hogsmeade. He has some special channels to get those rare and precious things. If you need anything in the future, you can consider sending an owl to him directly. Of course, the price will be more expensive."

"Hello, young man. I have seen your name in newspapers quite a lot recently." The old man smiled and stretched out his right hand.

"I'm glad to meet you, too."

Zuo Si pretended to stretch out his right hand and shook hands with the other party.

Because when Snape said that the pig's head would kill the boss, he realized that the person standing in front of him was Albus Dumbledore's biological brother.

Even if you use your butt to think, you will know that Aberforth's appearance here is definitely not a coincidence, but a deliberate arrangement by the greatest wizard of the contemporary era.

It’s a pity that the other party didn’t know that Zuo Si already knew everything.

After a brief greeting, Snape quickly took Aberforth to another table and started ordering food, while chatting in a very low voice.

After Isadora had filled her stomach, Zuo Si quickly paid the bill and left with the girl, disappearing at the end of the bustling street of Diagon Alley.

Not long after he left, Snape stopped eating, picked up his napkin to wipe his mouth, and asked expressionlessly: "What is your first impression of Soth?"

"Well... Overall it feels good. At least in some aspects he is much better than my brother. At least he is dating a polite and pretty girl."

Aberforth made a subtle insult to his brother with a double entendre.

Because the person Albus Dumbledore was dating was a man, and a dark wizard who had caused a huge stir in Europe.

Hearing this, the corner of Snape's mouth twitched slightly uncontrollably: "You should know that this is not what I meant."

"If you mean personality, I don't think it's a big problem. Because in Soth, I don't feel the same urgency and desire as that person. He is very calm, both mentally and internally. Such a person may become the second wizard like Albus, but his mind and thoughts will never be distorted by the power of dark magic."

Aberforth gave his judgment in a leisurely tone.

In his opinion, a young man who can maintain a calm state of mind while receiving so much praise at this age will never become as crazy as Voldemort or Gellert Grindelwald.

The most obvious characteristic of the latter two is that when they are young, they often have an impatient and strong impulse.

Not to mention these two people, even Albus Dumbledore was an impulsive guy with a certain fanatical emotion when he was young.

Otherwise he wouldn't have gotten involved with Gellert Grindelwald.

If Ariana's sudden death had not caused him to feel strong guilt and self-blame, he might have joined forces with Gellert Grindelwald to overthrow the Statute of Secrecy and directly established a world ruled by wizards.

Snape nodded slightly. "In fact, my point of view is the same as yours. Soth has intelligence and magical talent that others cannot match. His future is already bright. There is no need for him to emulate Voldemort or Gellert Grindelwald. It's a pity that Dumbledore's suspicious character always makes him suspicious."

"Humph! He is not being paranoid. It's as if he is seeing his better self in his youth through a mirror, and he is afraid that this young man will make the same mistake as himself." Aberforth snorted disdainfully.

"So... you are judging others by yourself?" Snape raised his eyebrows in surprise.

"That's right. Don't think of Albus as a saint. Strip away the series of honors and halos on him, he is actually just a loser who has lost everything, a poor guy who has been immersed in regret and pain for most of his life."

As he spoke these words, Aberforth's tone revealed naked and undisguised disgust.

If possible, he would rather exchange everything his brother had for his sister's resurrection, even if it was only for a day or a few hours.

"Okay, I finally understand how Dumbledore saw through my heart at first sight. It turns out that to some extent, he and I are the same kind of people."

Snape picked up the cup with a thoughtful look on his face, and at the same time, his mind flashed back to what Harry Potter's mother Lily had said to him after her death.

"To be precise, we are all the same kind of people, poor creatures with a heart full of guilt, regrets and a desire for compensation. Finally, I wish you a Merry Christmas in advance."

Having said that, Aberforth raised his glass and drank the wine in it, then stood up and left the restaurant without any delay.

Snape sat at the dining table for a while, until he finished the bottle of wine on the table before paying the bill and leaving.

When he reappeared in the Hogwarts Great Hall, Christmas Eve had already passed. Countless students and professors were sitting in the spacious hall on the first floor, enjoying the food and drinks that were provided round the clock.

Since there were no classes or difficult homework to do, everyone seemed very happy.

Especially those students who received precious gifts in the morning were constantly showing off to their friends.

Dumbledore obviously enjoyed seeing such a scene very much. Not only did he always have a faint smile on his face, but he also kept waving to the little guys who bowed and saluted him.

When Snape came over, he asked without turning his head, "Is everything done?"

"Well, yes, it's all done." The latter gave an affirmative answer without hesitation.

"You don't look happy?"

Only then did Dumbledore notice Snape's slightly depressed mental state.

This is totally inconsistent with his usual cold and gloomy temperament.

"Nothing, just remembering some things from the past. By the way, what's with those books on your desk?"

Snape obviously didn't want to talk about this too much and chose to change the subject directly.

"These?"

Dumbledore picked up one of the books and replied with a smile: "These are all Christmas gifts given to me by Soth. It is a doctrine that has only emerged in the Muggle world in recent decades.

It mainly talks about how to analyze what a person is thinking and what he will do next through words, behaviors, habits, experiences and other factors.

I have to admit that Muggles are indeed far ahead of wizards in this regard.

In addition, there are many explanations of the contradictions and struggles between ethics, morality, human nature and desire instincts.

After reading these books, I finally understood why Soth possessed such rationality and maturity that was totally disproportionate to his age.

To be honest, he was the first student who scared me.”

"Are you afraid too?" Snape asked with a surprised expression.

In his opinion, the old man in front of him had never been truly afraid of anything. Even when Voldemort's activities were at their most rampant, he still remained calm and rational.

"I am also a human being, and as a human being I will feel afraid. Believe me, if you have read these books, you will inevitably feel a little fear of Thors. Because if he chooses to walk the dark path one day, it will be an extremely terrible disaster for the whole world." Dumbledore explained solemnly.

"Like you were when you were young?" Snape couldn't help but ask back.

Dumbledore's eyes flashed with a strange light, and after a full minute he nodded and responded: "Yes, just like me when I was young. Even I am afraid of what the entire wizarding world would be like now if I had taken another path."

"What Aberforth said is indeed true. When you saw Thors, it was like seeing a younger and better version of yourself in the mirror. But don't worry, Aberforth also said that Thors at least took a girl on a date, which is much better than when you were young."

After saying this, Snape no longer paid attention to the frozen expression on Dumbledore's face, and quickly left the table and returned to his office.

It was not difficult to tell from the slightly upturned corners of his mouth that he was in a very good mood at the moment, even sweeping away his previous decadent mood.

Although Dumbledore and Snape trusted each other and could even put their lives in each other's hands.

But their relationship before was not very good.

Especially the private conversation after Lily Potter's death.

Every word Dumbledore said was like a knife, stabbing into Snape's broken heart, causing him to suffer for a long time to come.

Now that I have the opportunity to take some revenge, I will naturally feel very happy.

…

At the same time, Zuo Si, who was far away in London, England, was standing at the door of St. Paul's Cathedral with Isadora, gazing at this religious holy place with an ancient history that had been rebuilt and renovated many times.

However, unlike those ordinary people, he did not come here to pray, but to steal the power of faith that has accumulated and settled here for more than a thousand years, and to charge the divine scepter in his hand.

"Thoth, why do these people believe in a false god that does not exist at all? He will neither respond to the believers' prayers nor grant divine powers or blessings." Isadora asked in confusion through the mental connection.

“How should I put it? Actually, the reasons behind this are quite complicated.

Initially it may have come from ignorance, awe of nature and the universe.

But as time went by, it gradually evolved into a kind of thought, habit, power and tradition, and eventually integrated into all aspects of society and became a part of civilization.

Anyway, it is none of our business what these people want to believe, we are just recycling the wasted power of faith, that's all."

As he spoke, Zuo Si took out the artifact he had obtained from the underground of Askatla from his bag. With the help of the girl's mind control, he easily passed the church guards and entered the unopened church before other visitors.

Standing in front of the majestic high altar, he activated one of the scepter's abilities without hesitation.

In the blink of an eye, this building, which was first built in 675 AD and is even older than Hogwarts, suddenly surged with the power of faith.

In just a few seconds, the symbols of power on the scepter lit up one after another, emitting a dazzling golden light like the sun.

There is no doubt that Amaunator, the ancient sun god of Faerun, modified it to make it more suitable for his own divine power.

When all the power of faith in the entire church was drained, the entire scepter no longer looked dull as before, but instead exuded a chilling and terrifying aura.

Looking at the changes in the scepter in his hand and the amazing energy contained within it, Zuo Si immediately said meaningfully: "It is just as I expected. Any form of faith power can charge this artifact. It seems that this world is indeed suitable for operating as a rear base and refuge."

Obviously, since the power of faith of St. Paul's Cathedral can be absorbed by the scepter, then those historic religious sites in other places can naturally serve as a source of energy replenishment.

This means that the power of faith, which is extremely precious in Faerun, is almost everywhere in this world, and it is almost impossible to obtain it.

After getting what he wanted, Zuo Si immediately took Isadora out of the church.

After the two men left, ordinary people who came in to pray suddenly discovered that for some reason, the place lacked a sense of solemnity and sacredness.

Not only them, but even the priest who was in charge of the ceremony showed very confused expressions.

They would never know that just minutes earlier this historic church had forever lost its most precious and valuable thing.

From now on, the scepter that can release divine power shocks will officially be added to the reserve list as a trump card.

You have to know that this thing is not a secondary artifact like the Archmage's Staff, but one of the very few weapons that can truly pose a huge threat to the incarnations of gods and saints.

Before, Blind Eye had used half of the scepter when he was forced into a corner. Its terrifying power was feared even by legendary wizards like Erinikas.

"Thoth, do you want to become a god?" Isadora asked cautiously.

"God?" Zuo Si chuckled and shook his head. "No, I will not become a life form that is bound by beliefs and rules. Instead, I want to surpass them and become a more powerful and advanced existence."

"Surpass... God?!" Isadora was obviously stunned by this extremely arrogant answer, but soon an expression of excitement and excitement appeared on her face. "Then can I always follow you?"

"Of course. I have high expectations of you."

Zuo Si stroked the girl's head and gave an affirmative answer.

"I swear, I will never let you down." Isadora raised her chin slightly and promised solemnly.

In this way, in the last few days of the Christmas holiday, Zuo Si took the girl to many places, and even took modern transportation such as airplanes, trains and yachts to experience the convenience brought by technology.

It was not until the last day of the holiday that Isadora reluctantly passed through the portal and returned to the Mage Tower.

Because she knew that she had to work harder to prevent the gap between them from growing wider.

I bought all the things that interested me and might be useful in the second half of the semester, and stuffed them into the suitcase I made using the Traceless Stretching Charm.

After finishing all this, he leisurely boarded the express train back to Hogwarts.

During the trip, I also listened to Hermione talk about her experiences on vacation, and the interesting reactions of Mr. and Mrs. Granger when they saw various magical items.

Of course, the actual process was that Hermione was the only one talking, while Zuo Si smiled and nodded in agreement, but his attention was all focused on the book.

作为知识之神欧格玛馈赠，他手里的这本书可是记载了传奇魔法物品和神器的制造原理，还有无数就连烛堡都没有任何记载的古代魔法知识。

以左思目前的知识储备，竟然还会有相当多读不懂和无法理解的部分。

其中是涉及到了非常复杂的宗教和神秘学知识，还有些则像是来自无底深渊强大恶魔领主们的“创意”。

后者不仅极度邪恶扭曲跟混乱，而且看过后意识还会出现轻微的恍惚。

通过这本书，左思算是知道知识之神欧格玛为什么会遭到许多善神教会的批评。

因为他和自己的教会、追随者所保留的知识，有很多对于普通人乃至强大的施法者都非常危险，稍有不慎便可能造成极其严重的后果。

尤其是涉及到无底深渊、上古邪物等可怕的东西，哪怕是诸神也会感到恐惧。

所以从某种程度上来说，欧格玛才是整个费伦最危险、最可怕的神明。

他所掌握的禁忌知识，绝对足以将整个世界连带诸神一起彻底毁灭掉。

或许这也是为何，知识之神从来都没有真正意义上的敌人。

哪怕是希瑞克这样的疯子兼神经病，都从来不敢轻易去招惹欧格玛。

就在左思暗自猜测在知识之神的国度内珍藏了多少珍贵无比的书籍时，霍格沃茨特快列车终于抵达了目的地。

不少渴望与朋友分享假日见闻和趣事的学生们，纷纷拎着箱子跑进大厅或是各自学院的公共休息室。

看着这些小巫师精力充沛的样子，左思感觉自己阴暗的内心都照进了一丝亮光。

正当他打算返回寝室收拾一下东西的时候，韦斯莱家的双胞胎突然从左右两边冒了出来。

“嘿！索斯，圣诞节过得怎么样？”

“喜欢我们送的礼物吗？”

面对这两个活宝，左思不由得微微叹了口气吐槽道：“麻烦你们俩下次能不能送个正常点的东西？”

“他们送了你什么？”赫敏一脸好奇的问。

“一盒吃下去之后能够让舌头肿胀变大的软糖。”左思不加思索的给出答案。

“我们还给它起了个名字，叫做肥舌太妃糖。怎么样，很有创意不是吗？”乔治咧开嘴发出一阵大笑。

弗雷德也跟着解释道：“没错！这玩意很有趣，可以让你的舌头肿胀到一米长。我觉得它迟早能让我们赚大钱。”

不过赫敏没有理会双胞胎兄弟的自吹自擂，反倒是瞪大眼睛问左思：“你吃了？！”

后者嗤笑着摇了摇头：“当然没有。我又不是白痴，怎么会随便吃来历不明的食物。在使用了一些侦测咒语后搞清楚里边的小秘密，很快就丢到一旁了。”

“什么？你没吃！天呐！要知道做那一大罐子肥舌太妃糖，可是花费了我们整整一个礼拜的时间。”

听到自己的恶作剧没能得逞，乔治扑通一声便跪在地上发出了痛苦的哀嚎。

“该死！为什么！为什么你能看穿我们的阴谋？”弗雷德装出一副愤愤不平的样子怒吼道。

“白痴！”

赫敏没好气的翻了个白眼。

通过之前的合作，她已经知道这两个家伙其实拥有非常厉害的魔法天赋，只是都用在了“歪门邪道”方面而已。

不过其他学生倒是被乔治和弗雷德搞怪的样子逗得哈哈大笑。

原本还在被厄里斯魔镜困扰的哈利，更是笑得前俯后仰，完全忘记了那些让自己留恋不已的父母幻象。

很显然，在霍格沃茨很少会有人真的讨厌韦斯莱家的双胞胎兄弟。

因为他们总是能给身边的人带来欢声笑语。

闹了一阵子之后，大厅内很快就恢复了平静。

由于明天就要重新开始上课的关系，不少小巫师开始相互借作业，打算把假期里全部被抛之脑后的东西捡起来。

至于左思，把行礼送回寝室后，立刻便来到自家学院长的办公室报道。

正在调制魔药的斯内普头也不抬的问：“你的假期过得如何？”

“还算不错。我买了很多调制高级魔药的材料，下半个学期就要麻烦您多多指教了。”左思面带微笑的回应道。

“我倒是不介意给拥有足够天赋和聪明才智的学生一些额外指导。

不过你确定自己抽得出那么多时间吗？

圣诞节过后，魔法部预定的第一节课很快就要开始了。

届时不仅会有很多人魔法部的人前来，而且不少外国人和学校里的教授也会旁听。

如果你太紧张导致出丑，丢的可不仅仅是自己的脸面，还有斯莱特林学院和霍格沃茨的声誉。”

在说这番话的时候，斯内普的两只眼睛里透露出审视的目光。

左思一脸无所谓的耸了耸肩膀：“别担心，教授。虽然我也会紧张，但绝不会出现在这种情况下。至于课程安排，我早就已经全部准备好了。”

“全部？！”

斯内普脸上浮现出诧异的表情。

“对。毕竟魔法部可是花了大价钱，我总要对得起他们支付的酬劳。”

说罢，左思把事先准备好的备课笔记拿出来放在办公桌上。

斯内普下意识拿起来翻了两页，发现里边不仅整个课程由简到难分成了几个部分，而且每一堂课该讲什么也都列出了详尽的步骤，完全没有一丝一毫的混乱。

如果按照这上边的步骤上课，恐怕很多二三年级的学生都能听懂，更不用提一群成年巫师。

意识到这一点后，他立刻抬起头用不是很确定的语气问：“这也是你从麻瓜世界学到的？”

“没错。”左思略微点了下头。“在麻瓜学校里的老师，绝大部分都会在上课之前进行备课，有些甚至会在刚开学的时候就把一个学期的课程进度全部计划好。我虽然从来没有给任何人上过课，但也知道大概的步骤是什么。”

“好吧，希望到时候你的心理素质可以像现在一样好。”

斯内普随手将笔记还给了左思。

他现在终于有点明白，邓布利多为何会对一个一年级的新生感到恐惧。

像这种不管做什么都会事先做好万全准备的家伙，如果是成为敌人的话，将会远远比性格偏激、易怒的伏地魔更加可怕。

“我的第一堂课定在什么时候？”左思饶有兴致的问。

很显然，作为一个学生，他不可能在学期开始之后轻易离开学校。

所以校长邓布利多跟魔法部长福吉商量过后，把上课的地点选在了城堡内。

反正霍格沃茨有那么多的房间跟教室，找一个空出来的地方上课并不是什么困难的事情。

“三天之后的上午九点，具体地点会在当天早上通知你。”斯内普不加思索的给出了准确时间。

“非常感谢。如果没有什么别的事情，我就先回去了。”说着，左思单手抚胸略微欠了欠身，然后就准备掉头离开。

可还没等走出几步，斯内普就从后面叫住了他。

“等等！奎里纳斯·奇洛是不是给过你一本记载了很多关于黑魔法的笔记？”

左思立马转过身回答道：“嗯，没错。不过我觉得里边的内容太过肤浅、幼稚、低级，大概翻了翻就将其交给韦斯莱家的双胞胎兄弟了。他们正好需要一些恶咒来制作搞笑的小玩意。”

“肤浅、幼稚、低级？”

斯内普伸出手从自己的办公桌里拿出了那本书，脸上浮现出玩味的表情。

不用问也知道，他已经知晓了奇洛身上的伏地魔残魂，但故意装作什么都不知道，继续维持着自己双面间谍的身份。

这既是邓布利多的要求，同时也是他自己的选择。

斯内普很好奇，如果伏地魔知道了自己送出的笔记被一个学生评价为“肤浅”、“幼稚”和“低级”，究竟会作何反应。

“难道不是吗？”左思不以为然的反问。

“看看那些乱七八糟的咒语，有几个是真正实用的？

很多所谓的黑魔法，其威力还不如火焰咒、切割咒、昏迷咒、石化咒、粉碎咒、爆破咒、缴械咒效果更好。

巫师学习黑魔法是因为它拥有其他咒语所不具备的强大威力，而不是仅仅因为它是黑魔法。

如果搞错这一点，那就彻底本末倒置了。”

“说得好。”斯内普毫不吝啬的称赞道。“我很高兴你能在这个年纪就明白这样的道理。”

“拜托，教授。别把我跟斯莱特林学院那些总认为黑魔法就代表着很酷、很厉害的中二少年当成一类人。”

左思语气中带着一丝调侃的意味。

“更何况，真正决定一个咒语强弱的从来都是使用它的巫师。在邓布利多校长手中，即便是一个最普通的漂浮咒，只要他愿意，也可以造成难以想象的破坏跟杀伤力。”

Snape nodded in agreement. "It's not the spell but the wizard that's powerful? It seems that you are much smarter than I thought. Someone may have miscalculated this time. But you'd better be careful! Quirinus Quirrell may be a fool, but the guy behind him is very dangerous."

Zuo Si simply responded to the warning from his own dean with a nonchalant tone, "Please don't worry, professor. Maybe that person had very terrifying magical powers in his heyday, but he is just a remnant soul now. If I can't even handle such a pathetic state of half-death, wouldn't I have failed many people's expectations of me?"

"Don't be careless. You should know that some dark magic performed by him is completely different from that performed by other dark wizards." Snape couldn't help but remind him in a low voice.

"clear."

Just as Zuo Si turned around again and prepared to leave the underground office, Snape suddenly threw the notebook containing dark magic in his hand to him.

"Here, take your stuff. Remember, next time don't give this kind of stuff to other people, especially the Weasley twins. Otherwise, God knows what weird things they will develop."

Zuo Si grabbed the note, gave the other person an understanding look, and then disappeared into the corridor leading to the Slytherin common room.

About half a minute later, Snape slowly took out a pendant inlaid with silver-white crystal from his collar. He stared at the female illusion that appeared in the center, and a hint of tenderness and guilt appeared on his originally gloomy face.

Obviously, this thing was the Christmas gift given to him by Zuo Si, a magic amulet that could turn the person the wearer missed most into a lifelike illusion.

And these visions are the reappearance of precious memories.

No one except the wearer can see what is inside the crystal pendant.

Although Snape was not sure whether the gift was a coincidence or whether Zuo Si had learned from somewhere the relationship between himself and Harry Potter's mother.

But for him, this can indeed alleviate the strong longing in his heart to a great extent.

At the same time, Zuo Si, who returned to the dormitory, found that in the notebook that his dean had thrown to him, there was a piece of parchment covered with tiny handwriting.

There are two spells recorded above.

One of them is the famous "God's Shadowless Sword", and the other one is the counter-spell of the former.

"Is this a return gift for my little gift? Severus Snape is indeed a tsundere who doesn't want to owe favors to anyone easily." Zuo Si couldn't help but sigh slightly.

He finally understood why Snape, who possessed a very high IQ, could push his childhood sweetheart Lily Evans into the arms of his rival.

Apart from his obsession with the dark arts when he was young and his active allegiance to Voldemort, there was also the long-standing grudge between Gryffindor and Slytherin houses, and this unpleasant personality was also one of the reasons.

After all, no one would like a weird person who has too strong self-esteem and is unwilling to easily accept the kindness of his friends.

In addition, a cold-outward-but-warm-inward personality can easily be misunderstood as indifference and lack of humanity.

Zuo Si has always felt that accepting other people’s kindness and proactively helping others are equally important in interpersonal relationships and interactions.

But unfortunately, Snape has not realized this to this day.

He was clearly doing the most dangerous double agent job and trying his best to protect Harry Potter, but he was rejected, misunderstood and hostile again and again.

Maybe he never expected anyone to truly understand him from the beginning, or maybe his heart was already dead when he learned that his beloved was killed.

But anyway, Shadowless Strike is a pretty good black magic spell.

The reason why it is called black magic is that any area cut by the Shadowless Divine Sharpness cannot be healed normally before the counter-spell is used. Even healing spells and most potions will not have any effect.

This means that it can pose a huge threat to targets with strong regenerative abilities.

Most importantly, this spell is invisible and very suitable for sneak attacks and plots.

So Zuo Si studied it overnight and finally succeeded in making it into a card for the Planeswalker.

This was the first magic card he made in this world, apart from the land cards.

You know, even Fiendfyre, the Killing Curse, the Imperius Curse and the Cruciatus Curse did not receive such treatment.

After studying and researching, Zuo Si discovered that the essence of the Avada Kedavra curse was to forcibly deprive the target of its vitality.

If the wizard who casts the spell is powerful enough and has unparalleled murderous intent, he can naturally strip the opponent of all vitality in an instant, ultimately causing the irreversible result of death.

However, if the wizard who casts the spell is not powerful enough and lacks a strong killing intent, and at the same time the target has amazing vitality and magic resistance, then it will be impossible to kill with one strike.

Take the fire dragons in this world for example. The effect of the Killing Curse on them is quite limited, not to mention killing them instantly.

As for the Imperius Curse, its basic operating principle is similar to that of Faerûn's various charm and control spells.

Moreover, it is very easy to break free after being controlled for a long time, and its effect is very limited for creatures with strong will and strong magic resistance.

Perhaps among the three unforgivable curses, only the Cruciatus Curse can barely be considered a means of torture and interrogation.

In comparison, Fierce Fire is a very powerful means of attack.

But considering the huge harm that this thing may cause once it gets out of control, Zuo Si will not include it in the list of options until there are sufficient means of control.

After all, this world is so safe that even Voldemort seems so "harmless" to him, and many times there is no need to prepare and use overly powerful magic.

Even if you encounter some "little trouble" occasionally, you can easily deal with it with the spells you currently master.

Therefore, for a long time in the future, Zuo Si will shift his focus to learning and digesting the advanced theoretical knowledge, drawing inspiration from thousands of spells, and creating his own unique magic.

Before, he had invested too much experience in how to make himself strong in a short period of time.

Now is the time to calm down and understand the most basic and at the same time the most complex part of magic, and to move from being a mere user to being its true master.
