Zhang Xu believes that he is the happiest and most bitter of the many Harry Potter worlds.

The happiest is because he doesn't have Voldemort's sword of Damocles on his head.

The most bitter is because of the "Five-Year College Entrance Examination Three-Year Simulation Talisman" in my hand now.

In the professor's office of Muggle Studies, Zhang Xu, who had finished correcting today's homework, was fighting in the sea of questions.

On the table next to her, Fleur and Gabrielle are also writing their homework.

At this moment, a paper crane flew to Zhang Xu's desk.

It was a message from Snape that his office had been burglarized again, and that a lot of the potions materials he had added had been stolen.

The addition of African tree snakeskin is the penultimate step in making the polyjuice decoction, and if nothing else, little Barty will be able to drink the added compound decoction tomorrow.

More than ten minutes later, Zhang Xu received a message from Dumbledore asking him to go to the Headmaster's office.

After greeting Fleur and Gabrielle, Zhang Xu left the office.

When Zhang Xu came to the principal's office, there were only Snape and Dumbledore in the office.

Soon, the deans of the other three faculties also came to the office one after another.

Seeing that the three headmasters were so united today, and Zhang Xu was still there, "Could it be that Hogwarts has found a new source of wealth?" They thought.

Just as the three heads looked puzzled, Dumbledore spoke.

"One of the professors at Hogwarts is a Death Eater."

Professors McGonagall, Flitwick, and Sprout looked at Snape at the same time.

Snape's face turned white.

"I'm not talking about Severus," Dumbledore said, "and there was a Death Eater who entered Hogwarts disguised as a professor. ”

The professors weren't stupid, and they quickly guessed who Dumbledore was talking about.

After all, apart from the four Deans, there are only a few professors at Hogwarts.

Professor Binns in History of Magic class, you can disguise yourself as him and count you as a winner.

Hagrid's disguise to protect the magical biology class is too difficult, and if you are not careful, you will be killed by the textbook used in the class.

Sybil Trelawney, a professor of divination, is too elegant, and it is very difficult to imitate.

Professor Scarlett, who had only been here for a few years, had a harder time finding a wizard to take classes in her place than it was for Snape to wash his hair every day.

As for Professor Zhang, with his style of acting that is incompatible with the Hogwarts painting style, he is considered a success if he does not show his stuff for half a day.

In addition, several professors, such as Rolanda Hooch in the Flying class, Aurora Sinista in the Astronomy class, Setima Victor in the Arithmetic and Divination class, and Bathsida Babling in the Ancient Magic Writing class, have all taught at Hogwarts for many years, and are easily spotted by familiar students and colleagues.

After the elimination method, the answer is coming.

"You're talking about Professor Moody?" Professor McGonagall asked uncertainly.

"Yes," Dumbledore nodded, "our old friend, poor Alasto, who has been replaced. ”

"Who's that Death Eater?" Professor McGonagall asked.

"Barty Crouch Jr." Dumbledore uttered a name that surprised the three Headmasters.

"Barty Crouch Jr. kept Alastor looking by taking the Polyjuice decoction all the time." Dumbledore said, "We didn't do it because we were afraid that he would hurt the students. Until he stole some other ingredients in the Potions classroom tonight, his threat would be greatly reduced when he drank the compound potion made from these ingredients tomorrow. ”

"So when you get the news about Alastor tomorrow, please let the students go back to the common room or the auditorium. Then everyone will participate in the arrest of him. ”

In fact, Zhang Xu wanted to tell Dumbledore that he would do it now, and he was caught off guard by beating Barty Crouch Jr., but when he saw that Dumbledore had other arrangements, he gave up.

Dumbledore then took a copy of the Hogwarts Emergency Plan to deal with the details of tomorrow's operation, and said that he would have more important things to accomplish tomorrow.

Originally, there was nothing to do with Zhang Xu tonight, but who told him that the second class tomorrow morning would be the Defence Against the Dark Arts class.

According to Snape's estimates, there is a good chance that Barty Crouch Jr. will drink his previous stock before the first class tomorrow morning, and start drinking the compound decoction that he just brewed tonight during the second period.

So Zhang Xu took on the responsibility of dragging Barty Crouch Jr. in case of emergency.

From breakfast time to the second period, Peeves is in charge of keeping an eye on Barty Crouch Jr.

Tomorrow's action was arranged, and everyone left the principal's office.

Back in the Muggle Studies professor's office, Zhang Xu saw that Gabrielle had just finished her homework for the night.

Zhang Xu took Gabrielle's herbal medicine homework and sat on the sofa to check it.

And Gabrielle ran over and sat down next to Zhang Xu, for fear that Zhang Xu would find a mistake in it.

"In addition to the powerful healing effect, you forgot that chopped white fresh can also be used to make an invigorating potion, Gabrielle."

Zhang Xu, who was checking Gabrielle's homework, pointed out an oversight of Gabrielle, and then used the Flying Charm to make "A Thousand Magical Herbs and Mushrooms" fly to the coffee table in front of the sofa, and then opened the book and pointed out the relevant content to Gabrielle.

"Stick your face over," Zhang Xu said to Gabrielle with a smile, "If you say it's wrong, pinch your nose." ”

Gabrielle didn't listen to Zhang Xu's words, but covered her nose with her hands and tilted her head away from Zhang Xu.

Zhang Xu put one hand around Gabrielle's shoulder, and then scratched her itchy flesh with the other.

Taking advantage of the gap between Gabrielle blocking Zhang Xu's tickling hand with her hand, Zhang Xu pinched Gabrielle's little nose.

"Let me tell you, it turns out that the mysterious man in Britain has a nose, and then he was often pinched by Professor Dumbledore because he didn't do his homework well, so he has no nose now."

Zhang Xu was telling jokes while playing with Gabrielle.

Fleur was writing her homework while smiling and watching Zhang Xu and Gabrielle play.

After the two quarreled for a while, Zhang Xu continued to check Gabrielle's homework.

Next up is the Defense Against the Dark Arts assignment, and today's assignment for Gabrielle is a dissertation on the repulsion charm.

I have to say that Barty Crouch Jr.'s courses are mainly practical, and although the courses for junior students are not as scary as those in the upper grades, they are also very practical.

As can be seen in Gabrielle's paper, he explained the use of the repulsion charm in great detail in class, mentioning both formal and irregular usage.

In this respect, Barty Crouch Jr. can be regarded as an excellent professor.

When Fleur finished her homework, Zhang Xu also checked Gabrielle's homework, pinching Gabrielle's little nose several times during the process.

Seeing that the time was not too early, Zhang Xu sent Fleur and Gabrielle back to Beauxbatons' carriage together.

After Gabrielle returned to the carriage, Zhang Xu and Fleur took a routine walk outside the castle.

"Tonight you talk to Madame Maxime and the classmates, and if the alarm goes off in the castle tomorrow, you will go back to the carriage immediately, and if you don't have time, you will go to the common room or the Great Hall with the students of Hogwarts."

Taking advantage of the opportunity to take a walk, Zhang Xu reminded Fleur according to Dumbledore's meaning.

As for Durmstrong's side, no one greeted them.

Barty Crouch Jr.'s disguised Moody has been holding Karkaroff at bay, and if Karkaroff gets the news, something might happen.

"Did something happen?" Furong looked at Zhang Xu nervously and asked.

It's been a few months since she arrived at Hogwarts, and Fleur's feeling is that it's too dangerous here, and something dangerous happens every now and then.

"It's not a big deal, Hogwarts has rats, we're going to catch rats." Zhang Xu said, "For fear of rats biting students, students need to avoid them first." When the time comes, you can take care of Gabrielle. ”

Furong nodded after listening to Zhang Xu's words, and then changed the topic.

"I heard you like girls with green hair?" （）
