Drink Black Tea Calmly at Hogwarts

"I'm so stupid, really." Zhang Xu raised his dull eyes, and continued, "I know that Animagus can have long tails and change the color of their fur. I also know her The research on the false fire spell is very deep, and it can attach flames to the body when it becomes an Animagus. But I didn't expect that when she used these magics together, she would accidentally go crazy and couldn't change back..." He continued but whimpered, unable to utter a sentence.

On the roof of a tower in Hogwarts Castle, Zhang Xu sat on the ground leaning against the wall on the roof.

Scarlet sat beside Zhang Xu, hugged his knees, and looked at the sky together in a daze.

If she hadn't caught Professor McGonagall who was looking for Madam Pomfrey's help, things wouldn't have happened.

If she hadn't lifted the curtain of the bed when Zhang Xu was about to use the transformation technique to turn into a small animal and run away, and woke up Professor McGonagall who was going to pretend to be asleep, things wouldn't have come to this point.

Fortunately, today is the last day of the Christmas holiday. The students returning to school by train have just arrived at the train station. The few students who stayed in the dormitory are still waiting for dinner in the dormitory, so except for the three parties, the others People don't know exactly what happened.

After the Christmas holiday, Hogwarts resumed its usual activity.

After using the food additives provided by Zhang Xu, the dementors found that the effect was actually good, so they assured Dumbledore that they would not enter the Hogwarts wall for half a step. This was what Zhang Xu had agreed upon when he traded with the dementors.

Thanks to this, the ban on outdoor activities at Hogwarts has been relaxed.

On the first weekend after the holiday, a group of students came to the ice and snow castle and started a long-lost snowball fight.

Zhang Xu’s new way of playing was very popular. Everyone set aside a large area and let the students hurt each other with snowballs. The one who survived in the end was the winner, and the prize was a roasted chicken with honey sauce.

Because they had so much fun on the weekend, the students were a little bit overwhelmed when they went to class on Monday.

In the teachers' lounge, Lupine, who was resting after lunch, was preparing for the afternoon class. At this time, the door of the lounge opened, and a head came in and looked around, heaved a sigh of relief, and then the whole person got into the lounge. .

Seeing the sneaky Zhang Xu, Lu Ping laughed out loud.

"Zhang, are you still avoiding Professor McGonagall?" Lupine laughed.

"Zhang, why did you and Helleson make Professor McGonagall angry? I have worked with her for so many years,

It was the first time I saw her get so angry. asked Professor Sprout.

"Could it be that you and Helleson really plotted to seize the position of headmaster of Hogwarts as the students said, and Professor McGonagall found out." Professor Flitwick also said with a smile.

At this moment, Zhang Xu felt how Kong Yiji was treated when he was drinking in the hotel.

Zhang Xu waved his hand, expressing that he didn't want to answer their words, some things should be left to rot in the long river of history.

"Professor Lu Ping, do you have time tonight? There is something I would like to ask." Zhang Xu sat next to Lu Ping and asked.

"Well, no problem." Lupine replied after thinking for a while.

At eight o'clock in the evening, Lu Ping, who was invited by Zhang Xu to the Muggle Studies professor's office, was a little surprised when he saw Scarlett.

Soon, Zhang Xu told Lu Ping what he wanted to ask for advice.

"Professor Lupine, I know you have a lot of research on making magic items." Zhang Xu said while pointing to the Marauder's Map on the table, "Professor Scarlett and I want to make a portable Arnie Magus Probe, we would like to ask for your help."

Lupine's first reaction was that they knew that Black was an unregistered Animagus, so they made this probe to catch Black.

In the next second, Lupine dismissed the idea. Because he thought of the fact that Zhang Xu and Scarlett made Professor McGonagall angry some time ago, and that Zhang Xu fed the dried fish to Professor McGonagall who turned into a tabby cat in the first Transfiguration class. deeds.

So Lupine thought he had guessed the truth. He guessed that Zhang Xu and Scarlett fed Professor McGonagall a small fish again.

Lu Ping, who suppressed a smile, agreed to Zhang Xu's request and said that he could study the Animagus detector with them.

Next, Zhang Xu and Scarlett introduced the design ideas of the detector to Lu Ping, as well as the difficulties encountered so far.

Lupine's level of making magic items is indeed not low. The Marauder's Map made with a few friends when he was a student is a must.

Zhang Xu has done research on the Marauder's Map, and found that there are many magics used on it. I won't talk about the simple ones such as the appearance of the background map. The tracking spell above is an extremely high-end spell, and it also involves the relationship between the name and the magic power. Relationship.

What interested Zhang Xu the most was that Lu Ping and the others even injected a little of their own thoughts into it. Before that, another thoughtful magical item at Hogwarts was the Sorting Hat.

You know, if this technology is used well, it can be used as artificial intelligence in the future.

Moreover, the Marauder's Map actually has an administrator function. Lupine and the others blocked Snape from the very beginning.

Recently, Zhang Xu also discovered that the Marauder's Map has been tampered with recently, and Peter Pettigrew's name will be automatically replaced with "Banban". This explains why for so long, the Weasley twins didn't find out that their sixth child slept with a man named Pettigrew Peter every night, and why Lupine, who was also an administrator, could see Pettigrew Peter's name.

It would all make sense if Peter Pettigrew found out that the twins got the Marauder's Map, and took his own chance to quietly tweak the settings of the Marauder's Map.

Zhang Xu has a background in alchemy, and he has discussed with Dongia a while ago about improving the Horcrux detector, and his performance made Lu Ping look at him with admiration.

The three of them discussed in the office for more than two hours, and finally finalized the preliminary design of the Animagus detector, and the rest was relatively low-difficulty work and the hands-on link.

After finishing tonight's research, everyone left the office together.

On the way, Zhang Xu asked Lupine about Harry learning the Patronus Charm.

"You know, Harry didn't study well at first, and his past experience was really bad." Lupine said, "But it's getting better recently, and he'll be able to master the spell soon."

"That's good, otherwise if the dementor breaks the agreement and breaks into the campus again, Harry will have to be blown away again. I don't want to win Saturday's game and be said that we rely on dementors That's why we won the game," Zhang Xu said.

"How is your Patronus Charm?" asked Lupine.

When Zhang Xu suggested that Harry go to Lupine to learn the Patronus Charm, he just sat aside to study, but he learned much faster than Harry. After all, he's experienced many happy things, "Missouri" can make a cloud of silvery white smoke shoot out from the tip of his wand.

"It's okay," Zhang Xu replied, "I can make them do some simple movements."
