Zhang Xu sent Fleur to the Eurostar before returning to Hogwarts from London "biu".

It's also because Zhang Xugang helped Lao Deng do a black job, otherwise Lao Deng wouldn't have let him run around like this. I have to say that in terms of treating his own people, Lao Deng is still very preferential.

Zhang Xu returned to Hogwarts and entered the classroom ten seconds before the class bell rang.

The class was math, and Professor Scarlet was disappointed that he couldn't deduct a student's mark for being late.

The math class is also taught by the two colleges, and when the class was arranged, Zhang separated the Lion Courtyard and the Snake Courtyard in order not to have much to do, and it was the Lion Courtyard that took classes with the Eagle Academy.

Zhang, who was sitting in the last row, glanced at the students present and noticed that a yellow head had turned back to red.

Today's class content is curves and equations, Zhang Xu put the textbook on the table, and then took out today's "Prophet Daily", until now he has time to read today's newspaper.

Unlike other students, he couldn't understand the rest of the content after five minutes of distraction in class.

The front page of the newspaper was the Minister of Magic, Fudge, appealing to the masses to remain calm, and the minister said that the series of cases that occurred the day before yesterday were just a handful of Death Eater remnants doing their final death struggle, not the rumored return of the mysterious man, and the Ministry of Magic was confident and capable of sweeping away these Death Eater remnants and giving the people a stable and peaceful living environment.

Seeing that Fudge was still dying so hard, Zhang Xu couldn't help but grin and sneer.

At that moment, there was a sound of breaking the air in the air.

Zhang Xu's head subconsciously deviated, and a piece of chalk flew past his temple, and then smashed on the wall behind Zhang Xu with a "snap".

Putting down the hand that threw the chalk, Professor Scarlett asked, "Why is Mr. Zhang laughing?" ”

Zhang Xu, who was named and stood up, naturally couldn't say that he laughed when he saw the Minister of Magic's posture, so he could only use his wits and say: "I just thought of an equation x²+(y-(x²)^(1/3))²=1, and its graph is very interesting. ”

Professor Scarlett thought for a moment and sneered, "Hehe, this is all a little trick I've played before I don't know how many times. ”

Then Scarlet raised his wand from the podium and waved it, and the newspaper on Zhang Xu's desk floated up.

"Ravenclaw deducts five points, confines for three days, and comes to my office at eight o'clock tonight."

As soon as Professor Scarlett finished speaking, the newspaper in front of Zhang Xu turned into a ball of fire.

After a math class, Professor Zhang went to the Muggle Studies professor and began to prepare for today's lesson.

Less than a minute before class, a dashing wizard with brown hair and bushy eyebrows, albeit a little lame, walked with a stride into the classroom.

"Master!"

This was Zhang Xu's first reaction to him.

"Rufus Scrimgeour, Director of the Auror Office of the Ministry of Magic."

Zhang Xu quickly recognized the visitor.

Rufus Scrimgeour walked into the classroom and only found a seat in the corner of the last row, then nodded at Zhang Xu, motioning for him to leave himself alone.

Zhang Xu ignored him and went to class as usual, but the other students were not so calm.

Although the students did not dare to talk to each other, all kinds of speculation sprouted like weeds in their hearts, and various reasons for the Auror Office of the Ministry of Magic, Rufus Scrimgeur, to personally arrest Professor Zhang.

However, the students who wanted to see the excitement were doomed to be disappointed, and after class, Professor Zhang went straight to his seat and sat next to Scrimgeur, and then talked and laughed.

Scrimgeour's non-angry and self-righteous appearance has a lot of impact on ordinary people, but it has no impact on Zhang Xu.

Scrimgeour took out a stack of photos and handed them to Zhang Xu, then asked, "Do you know the man in the photo, Mr. Zhang?" ”

Zhang Xu took the photo quietly, and then looked at it carefully one by one.

f,f connected to restore all of Conan's actions in front of the front desk。

"Did he doubt himself, or did he just ask because he was also from the East?" Zhang Xu thought while looking at the photo.

"This is supposed to be Japanese, but I don't know him." Zhang Xu flipped through the photo and said.

"Are you sure it's Japanese?" Scrimgeour asked.

Zhang Xu pulled out two photos and placed them on the table in front of Scrimgeour, one was a photo of Conan handing his wand to the wizard on duty at the security checkpoint, and the second was a photo of Conan saying goodbye to the wizard after the security check.

Zhang Xu pointed to these two photos and said to Scrimgeur: "In several countries in East Asia, people from different countries have some behaviors and habits that can distinguish them. ”

"When he handed the wand to the wizard who was inspecting, and when he said goodbye, there were natural signs of bending and bowing, especially since the angle of the two bows was almost the same, which showed that the person's bow was a habitual action. If you can compare it to wizards from several other countries, this kind of action is most seen in the Japanese. ”

"In addition, the angle at which they bow and bend is different when facing people of different statuses, and the higher the status of the person they bow to, the greater the angle of bending."

Scrimgeour looked seriously at the two photos with bowing movements on the table, and soon realized that what Zhang Xu had just said was true.

Zhang Xu is not afraid that he can see the flaws in the photos, after all, he has played the Japanese many times back then, and even authentic Japanese can be deceived by him.

You know, it's not easy to communicate with people from other countries pretending to be from another country, and sometimes language issues can make people flawed. During the self-defense counterattack on the southwest border that year, the pronunciation of the Vietnamese language "surrender the gun and do not kill" was "Nuo (cloth) pine empty leaf", but many soldiers omitted the soft-sounding "cloth" when shouting, and as a result, the more they shouted, the more fierce the gun was fired on the other side, and finally when the prisoners were interrogated, they knew that "Nuo Song empty leaf" meant "shoot and not kill".

Scrimgeour asked Zhang Xu about Conan's wand, and Zhang Xu was sure that there was nothing wrong with the introduction of the wand.

After Zhang Xu got the information he wanted, Scrimgeour took his leave and left.

When Zhang Xu came to the cafeteria, dinner had just appeared on the table.

Zhang Xu sat in his usual position, and when he took a piece of lamb chop from the plate in front of him, he turned his head and just wanted to say something to Zhang Qiu, but as soon as Zhang Qiu saw Zhang Xu turn his head, he immediately slipped to the other side of the table with the plate.
