Chapter 138 The Passerby Who Didn't Get the Owl in Harry Potter 15
"Did you invent that mirror that lets you talk to your family?"
Jiang Yue took out several mirrors from her bag and handed them to the headmaster: "Yes, you can't make phone calls at Hogwarts. Owls are too inefficient at delivering messages. After studying runes and alchemy, I made these mirrors based on the principle of two-way mirrors."
"Why are the three mirrors different? This mirror is obviously much more advanced than the other two. Has it been upgraded?"
"Yes, Principal, the one you have can be bound to your body by dripping blood, and it comes with a powerful protective spell that can block one fatal attack. The regular version of the mirror doesn't have this function. Now it has functions such as video calls, text chat, sending voice messages, sending pictures, and Moments."
Jiang Yue basically ported all the functions of WeChat to it, and even used some technology from the cultivation world. She planned to cooperate with Hogwarts to make some money. She needed money for research materials and so on. She also planned to stock up on some magic potions. Jiang Yue did not plan to sell the advanced version, but only give it away. She would only sell the ordinary version.
The principal trusted Jiang Yue and wasn't afraid of her casting any curses. He took out a drop of blood and dripped it onto her. After seeing the blood absorbed, Jiang Yue said, "Principal, just think about absorbing it into your body."
The headmaster closed his eyes, thought for a moment, and the mirror disappeared from his hand, only to reappear shortly after. He then input magic to power it on and saw four functions: Chat, Contacts, Discover, and Personal Information. Since there weren't many, Dumbledore quickly understood them and asked Jiang Yue, "How do I add friends?"
Jiang Yue took her mirror and touched it to the principal's, saying, "That's it, just touch the two mirrors together." It's not very intelligent now because there's no central server; everyone's information is stored locally. You can't add friends remotely, and you can't add strangers. At the very least, you need a mutual friend. For example, A, B, and C don't know each other, but B knows both of you. B can push A's identification information to C, and then you two can add each other as friends.
If you update your personal information, others won't see it immediately. It requires two people to contact each other before the information can be updated. If there's no further contact, the information displayed on their end will be the old information. The method of storing information is a modified version of the Pensieve, and the amount of information stored is limited.
Jiang Yue then mentioned wanting to partner with Hogwarts to make money in business. The headmaster had no objection to this, as he was researching the blood oath function. The other functions were deciphered in no time.
“Your idea is novel. Although there aren’t many people outside who understand runes, there are quite a few pure-blood families who do. If we don’t take some precautions to keep it secret, it will be cracked in no time. This needs to be done, but not now. I’ll visit my old friend during the holidays and ask him to help improve it and do some encryption work.”
“Okay, then I’ll leave this to you.” Afterwards, Jiang Yue explained the complete WeChat functionality to Headmaster Dumbledore. After listening and thinking for a moment, the headmaster said, “So your idea is so comprehensive. I was wondering why it felt incomplete when I was using it.” After saying that, Dumbledore asked for some more details and wrote them down.
After discussing this matter, Dumbledore did not mention Harry Potter again, nor did he inquire about the origin of Jiang Yue's knowledge. It is possible that he had already understood during the conversation. He then gave her permission to borrow his private collection of books from the headmaster's office at any time. What Jiang Yue did not know was that Dumbledore had already placed her on the list of people he could trust, even though Jiang Yue herself did not know why.
After a busy night, Jiang Yue went to the school clinic to check on Hermione and the other two. After that, she went back to her dormitory to catch up on sleep. Actually, Jiang Yue had an impulse today to just give Dumbledore the complete Harry Potter collection. The main reason she didn't was that Jiang Yue was afraid Dumbledore wouldn't be able to accept it and would just die. After all, he's getting old. She'll slowly reveal some information to him in the future.
After waking up, Jiang Yue examined her Animagus form. Unfortunately, she hadn't become a complete magical creature; she could only be considered a semi-magical creature. Her evolution was incomplete, but she had gained some magical creature abilities. She could control the wind and fly faster, and her stamina had increased significantly. According to Bai Ze's calculations, if she ate more monster meat and spent more time with Fox, she might become a true magical creature. Jiang Yue's human form also underwent some changes, gaining the ability to control the wind, which was probably a result of her evolution.
Hermione came to check on Jiang Yue once during this time, and after making sure she was alright, she went back to take care of Harry and Ron. The two of them were still bedridden and unable to get out of bed. Jiang Yue brought some fruit to visit them. Harry wanted to talk to Jiang Yue about what had happened next, but unfortunately, Madam Pomfrey kicked her out. Patients need to rest, and if it weren't for the fact that Jiang Yue had come with Dumbledore that day, they wouldn't have let her in. Jiang Yue gave an apologetic look and turned to leave, leaving the question for Headmaster Dumbledore to explain.
A few days later, after Harry was discharged from the hospital, the year-end banquet began. Dumbledore tallied the total scores of each house: Slytherin was first, Eagle was second, Badger was third, and Gryphon was fourth. After Dumbledore added a lot of points, Gryffindor became first, Ravenclaw second, Slytherin third, and Hufflepuff last.
"Glory to Gryffindor!"
After Dumbledore made the announcement, everyone except the Slytherin students was overjoyed. Finally, someone had broken Slytherin's record of seven consecutive championships. After the year-end banquet, everyone boarded the train home. When they first enrolled, Harry, Ron, Hermione, and Jiang Yue were in the same carriage, and after the first term, they were still in the same carriage.
While chatting in the car, Harry and Ron looked at Hermione and Jiang Yue with awe. After all, it was normal for the two underachievers not to understand the discussion between the top and second-best students in their grade. Ron even complained to Harry, "Is this what top students are like? They need to study all the time?"
"Maybe, otherwise why would they have achieved such good results?"
Hermione was about to launch into her lecturing mode, but Jiang Yue stopped her. Who wants to listen to this on a happy holiday? So Ron found some wizard chess to pass the time. Hermione wasn't interested and thought it was too violent. In the end, Harry and Ron went first. Harry was defeated. Jiang Yue then went on to play but lost two games in a row. Finally, Jiang Yue couldn't stand Ron's smug look and said, "Bai Ze, activate!"
After using cheats, Ron lost three games in a row and began to doubt his life. The two people next to him watched Ron get thrashed. It was because he always bragged when he won a game. Ron even asked, "Why didn't you play the last game? Your chess skills are so strong."
"Because at that time, there was only one way to win, which was the way you played, and I couldn't sacrifice myself, so..."
Ron blushed at her words. While the three of them were talking, Jiang Yue breathed a sigh of relief, finally managing to get away with it. She couldn't be so smug in the future.
