Ron spoke loudly, he was very confident in himself now.

In his first and second years, Harry still didn't think he could beat Malfoy.

But now I can easily beat him, if I hadn't been careless and didn't dodge...

"You're in a bad mood?" Hermione put down her book, moved the bench, and sat closer to Harry. "Did you find nothing after you went there?"

There were other people in the lounge, so Harry lowered his voice and said, "It's not like we found nothing. There's a little surprise that can solve some problems."

Hermione nodded and moved closer.

The fireplace became quiet again, and they began to read. Ron applied the plaster and retreated to the table to continue his homework.

Occasionally, a few sparks flew out, and Crookshanks chased and played. He didn't continue to play with the Sorting Hat. Now the hat couldn't talk, it didn't move, and it was meaningless. If the hat couldn't talk, it would lose the meaning of being a cat scratching post.

Harry was very busy during the Christmas holidays.

On the way to class every day.

But it was very fruitful.

Professor McGonagall was stricter - although not as strict as Harry pushed himself - and Professor Sprout began to teach him how to use some more dangerous magical plants, more dangerous than biting kale.

Professor Flitwick was immersed in studying the sigils. He hadn't figured out the principles behind this gesture magic yet and was eager to figure it out. Even if he couldn't use it himself, it would be good to develop a few more gesture spells for Harry.

This was the first time that Professor Moody had experienced this kind of "extracurricular confinement" and he seemed a little uncomfortable with it.

In terms of ability, he was slightly inferior to the dean, so he could only tell Harry the experience he had gained over the years on how to deal with dark wizards. This was very useful, and Harry listened carefully, and by the way, he called Hermione and Ron as well.

This kind of knowledge, which is not beyond the syllabus, is completely within the scope of their learning and mastering.

Detention with Professor Snape was the most useful thing for Harry after Professor Dumbledore.

The "Snowstorm Potion" that Harry had been dreaming of was finally developed.

Using the lucky spirit potion as a template, the eggs of the fire ash snake, the blood of the phoenix, and the blood of the unicorn are the most core materials. By extracting the essence from them, you can boil down this potion.

The effect is terrible.

Snape used mice to test the drug, and released Crookshanks, Hedwig and Bows. The three of them besieged the mouse together, but they couldn't catch it after fifteen minutes - and the reason for the time limit of "fifteen minutes" was that after such a short time, the mouse would be burned into an idiot, with its brain damaged, and it would stand there stupidly, like a vegetable.

This is a terrible potion.

Snape hesitated for a long time before he dared to let Harry try it. He watched him the whole time until the effect of the drug wore off. He was relieved when he was sure that Harry's heartbeat was just slightly faster and his face looked a little hideous, but he was not as fragile as a little white mouse.

The surprise is not just this bottle of potion.

And "Swallow".

The most favorite magic potions of the demon hunters are the recovery potions such as "Swallow" and "Oriole", after all, we only have one life.

"Swallow" is a magical potion that will continuously heal wounds on the body after taking it. It can even ensure that the wounds will not be torn during battle. Unless you are hit again, the wounds will continue to heal.

Snape was a great potions master.

Not only did he recreate the effect of the "swallow", he even incorporated the effect of the oriole.

Phoenix tears, mandrake extract, and unicorn blood were brewed at midnight when the full moon came, and the golden potion was finally brewed at noon the next day.

This was just right for Harry.

But... for ordinary creatures, this is still a bottle of poison.

Snape still used the little white mouse for the experiment. After cutting it open, he fed it a drop of swallowtail. Within just ten minutes, its cut internal organs and opened stomach healed rapidly. But that was not the end. The potion continued to work, and granulation tissue grew out of its body. Half an hour later, when the effect of the potion ended, the little white mouse grew into a fist-sized ball of flesh, rolling around on the table, making a cry of full energy.

It is still a potion that only works on Harry and has no effect on ordinary people.

"You now have three super-sized potions in your hand." After a day of remedial lessons, Snape looked at the two bottles of potions on the table. "With your current body, you can only take two bottles at the same time within an hour."

"I know exactly," Harry agreed.

Snape sneered and swung his empty sleeves: "Mr. Potter, I have tolerated you for a day. Now please leave quickly. I have to..."

"Professor, I have another request." Harry interrupted him and spoke softly.

Snape was startled.

Harry took out a piece of parchment from the Sorting Hat and placed it on the table. "It's a potion formula, but I'm not sure if it works. I need your help to revise it."

Snape reached out and picked it up. After just one look, his eyes immediately became sharp and full of anger. He squeezed out a few words from his throat: "Potter! If you don't want the brain, give it to Dumbledore instead of ruining it like this!"

"What do you want to do?"

"Want to fulfill the Dark Lord's wish before he kills you?"

"Or has the Potter blood finally tainted you, leaving your mind empty?"

Snape dropped the paper.

What was written on it was too unorthodox. The heart, blood and eyeballs of a fire dragon were directly used to make the potion without any extraction or purification steps, and things like the venom of an eight-eyed giant spider were also added.

The toxicity is so strong that it is even stronger than the three bottles of potions made previously combined.

Harry said calmly, "Professor, I am very self-aware."

"The fire dragon is such a good material, we can't just waste it like this."

Snape said coldly: "It's a waste for you to do this."

"Only by doing this can we maximize the medicinal properties of the dragon." Harry said firmly.

There are two kinds of potions that witchers commonly use.

One is a magic potion, which is less toxic and takes effect for a very short time, usually only lasting thirty to forty minutes.

The other method is to decoct the medicine, which takes a long time to take effect, basically measured in days, but the price is that it is very toxic.

The recipe he gave Snape was a kind of decoction, but it was different from any decoction he had taken before - after all, in this world, he couldn't get those ingredients, so he could only settle for the second best and use the decoction formula as a blueprint for his own exploration.

Snape took a deep breath and resisted the urge to draw his wand: "Potter is Potter after all!"

"Thank you, Professor." Harry heard his "hidden meaning" and nodded in thanks, then was about to get up and leave.

Snape drew his wand and waved it lightly, and the chair flew forward, blocking the door.

"Professor?" Harry turned around.

Snape's voice was extremely cold: "Materials, leave the materials behind. No matter how great a potion master is, if he doesn't have the materials, he won't get any results just by calculating on the parchment."

"Professor, you could be more straightforward." Harry tapped his wand lightly, and a bunch of bottles and jars flew out of the Sorting Hat and landed gently on the table. "Please rest assured, I'm not so stupid as to casually stuff something I don't understand into my mouth."

Snape sneered, "Potter, I don't think you are so wise."

Harry was about to push the door open and walk out, but he suddenly stopped: "By the way, Professor, where is Karkaroff?"

"No news." Snape's face darkened. "He is a coward, a wimp, a piece of trash who is still alive but whose body has already decayed. Damn it, he still hasn't made up his mind."

He was a little anxious, staring at the fresh dragon heart in the bottle on the table.

"Where are the other Death Eaters?" Harry asked again.

Snape sneered, "Do you think my brain was dug out and eaten by a troll like you? I have contacted them a long time ago, but those I contacted probably didn't get any news. They felt that the mark was getting stronger and stronger, and they were getting more and more panicked."

"The people I thought were qualified to know about these things have all disappeared."

Having said that, he paused.

"Remember Corban Yaxley?" Snape inquired.

Harry nodded.

On the day of the Christmas ball, Snape said that he was one of the three people who were given power by Voldemort and were qualified to mobilize other Death Eaters.

"I suspect he's the one who did it." Snape gritted his teeth. "He's working for the Ministry of Magic now, but I can't contact him! There's no worse place than the Ministry of Magic. An employee took a four-month leave just because he was not feeling well!"

"It's been four whole months, and there haven't been any problems in his department!"

"Really?" Harry frowned.

Snape took a deep breath and tried his best to calm himself down. "I will convince Karkaroff as soon as possible to contact those guys and find out what they are doing."

Harry thanked him again and walked out.

When I walked out of the underground corridor and looked out of the window, I saw heavy dark clouds outside. After a brief break of a few hours, it seemed that it was going to snow again.

Christmas is over and students are facing the backlash of the holidays.

The professors all seemed to be in a bad mood and became a little irritable. They were stricter with the academic work and the homework papers were one or two inches longer than before, which made the students complain.

Harry would occasionally see Malfoy in the Great Hall, sitting politely at the end of the long table with his chest puffed out and manners observed, enjoying his food alone.

He had new injuries on his body almost every day, and occasionally he would be seen being played pranks on him - these were not done by George and Fred, they said they had greater causes to pursue now, these pranks were all from Slytherin.

Malfoy completely lost the respect of the Slytherins because he failed to defeat Ron, and even the half-bloods dared to bully him.

Malfoy was less vulgar in this regard.

At least he knew how to resist, even though resistance often led to more and bigger "pranks".
