Things seemed to be getting a little out of hand, and the students' antagonism with Umbridge intensified from the day the newspaper reported that Harry and Neville had injured their hands.

On Tuesday night, Zhang Xu had just finished his holiday homework in the Muggle Studies professor's office when the door to his office was pushed open.

Dennis Creevey, who had simply bandaged his arm, was sent to Zhang Xu's office by his brother Colin Creevey and several students from the Lion Academy.

At the same time, Colin also handed Zhang Xu a photo of Dennis's bleeding hands.

After a while, Harry and Neville came over, and their wounds began to bleed again like they had done yesterday.

In desperation, Zhang Xu wrote two notes and folded them into paper cranes, asking Professor Barblin and Madam Pomfrey to come over.

This morning, Professor Babling took Harry and Neville to the school infirmary, where they were carefully examined for their injuries.

At noon, Professor Barblin found Zhang Xu in the faculty lounge and asked him carefully about the wounds he had examined Harry and Neville the previous night.

According to Professor Babling, she wanted to use this to brush up on a paper.

As one of the few research fanatics at Hogwarts, Professor Barblin has always had a good reputation in the wizarding community.

Dumbledore and the four Headmasters were not low, but the day-to-day management took up so much of their time that they rarely published results.

Now that the three guinea pigs are coming, Zhang Xu naturally wants to call Professor Barbling, and then call a professional like Madam Pomfrey to come and bandage them.

Before Professor Babling and Madam Pomfrey came over, Zhang Xu learned about the day's situation from the three wounded.

First, during the Defence Against the Dark Arts class during the day, Umbridge denigrated Harry and Neville in class, and then Dennis took the lead in retorting. As a result, Dennis went to confinement together at night.

In Umbridge's office that night, Umbridge asks Harry and Neville if Dumbledore instructed them to tell the Daily Prophet about their injuries.

Harry and Neville, of course, denied it.

After repeated questioning, they did not get the results they wanted, and Umbridge increased the punishment to them.

Zhang Xu thought for a moment, if Umbridge heard the wind and knew that this matter had something to do with him, then it would not be fun for her to break in when Professor Babling was researching.

So Zhang Xu went down the hallway and called Peeves and told him to go to Umbridge's office to cause trouble.

It didn't take long for the researchers, the three researchers, and the aftermath handlers to arrive, and everyone began to work on the research.

Zhang Xu repeated yesterday's examination of the wound and gave a detailed explanation to Professor Barbling.

The next step is Professor Barburing's research work.

Zhang Xu saw that it was late, so he left the medicine he had used yesterday, and asked Colin to remember to help turn off the lights and doors of the office after leaving, and then went to the screaming shack and Fleur for a routine phone call.

When Zhang Xu returned to Hogwarts Castle, the research in the office continued.

With the exception of the three researchers, who looked helpless, and Colin, the newly promoted research recorder, the rest of the students had already returned.

Zhang Xu walked out of the office door and quietly called Dobby, asking him to take all the photos of Dennis that Colin took today to Hogsmeade's owl room and send them.

After walking back to the office, Zhang Xu was called by Professor Barbling, and she had some questions that she wanted to hear Zhang Xu's opinion.

"What do you think about this magic?" Professor Babling asked.

At the same time, she handed Zhang Xu a few pieces of parchment, on which were some notes she had just taken.

After reading the notes, Zhang Xu thought for a while and said: "This magic is to make the quill connect with the body and soul of the holder, in terms of body, with the first pen point as the origin, a plane Cartesian coordinate system is established on the paper and the body of the pen holder at the same time, and the movement trajectory of the quill is magnified proportionally and reflected on the body of the pen holder." ”

After Zhang Xu finished speaking, he took out a few pieces of white paper, and then used an automatic drawing pen to draw several plane Cartesian coordinate systems on them, and then drew the handwriting and wound images of the three mice on them.

As can be seen from the images, the handwriting and the shape of the wound are exactly the same, and some of the writing habits of the three mice are reflected in the wound in the slightest.

The three mice also listened attentively to Zhang Xu's analysis, and then thought about how to reduce their damage next time.

When Zhang Xu finished analyzing, he noticed that there was an elegant smell of perfume wafting beside him, and at the same time, there was a faint smell of disinfectant water.

At this time, Zhang Xu realized that Professor Ba Buling had stood on his right without knowing when he had noted, and listened intently to his analysis of the relationship between his handwriting and the image of the wound.

And Madam Pomfrey stood to Zhang Xu's left, and she would not leave anything related to the wound.

Zhang Xu looked at Professor Barbling's handwriting again, and then found a detail at the back that he hadn't noticed just now.

"Huh? Harry, you used a mechanical mind today? Zhang Xu asked.

"Yes." Harry replied, "But I didn't use it very well, and after using it, I found that the wound didn't hurt as much when I wrote." ”

"What kind of magic is that?" Professor Babling asked.

As soon as she had recorded this message, Zhang Xu returned, so she couldn't ask Harry for the details of the spell.

Zhang Xu didn't explain much, but let Professor Barburing experience the effect of this spell firsthand.

Two minutes later, when Zhang Xu lifted the spell, Professor Ba Buling looked at Zhang Xu's eyes as hot as Zhang Xu looked at Lipu taro buttoned meat.

After promising to teach her the spell in the future, Professor Barblin turned his attention back to the mice.

It's just that it's too late today, and the relationship between the guinea pig's wounds and their emotions can only be saved for the next day.

After Madam Pomfrey bandaged the wounds of the three mice, everyone went back to sleep.

Zhang Xu, who returned to the dormitory, made Dennis and Umbridge's damage transfer type puppets, and then put them in the drawer of his desk, together with Harry and Neville.

Originally, Zhang Xu planned to start these puppets tonight, but Professor Babling's mess disrupted his plan, and he had to wait for Professor Babling to brush out the paper.

After the arrival of the Daily Prophet on Wednesday morning, the students were in an uproar again, and the photo showed one more victim.

In the professorship, Umbridge's face was terrifyingly dark.

In the evening, Professor Barburing's guinea pigs expanded to include students at Eagle Yard and Badger Academy.

Things were fermenting further, and when Malfoy and Ye walked into the Muggle Studies professor's office on Thursday night, Zhang Xu didn't know what to say except "lying on the grass".

Zhang Xu grabbed Malfoy's collar and pulled him out of the hallway.

"What the hell are you doing?" Zhang Xu asked, "You told Umbridge that the Dark Lord lives in your house?" ”

"You...... How do you know? Malfoy's face turned pale with fright.

"Your house is the biggest among the Death Eaters, so if you don't live in your house, why don't you go to the Leaky Cauldron Bar to open a room?" Zhang Xu said.

"My father said that the Dark Lord asked me to approach you quietly and let me bring you a message, he wanted to meet you." Malfoy said tremblingly.

"Then this Halloween, in the mountains near Hogsmeade." Zhang Xu said.

After letting Malfoy enter the office by himself, Zhang Xu simply went to the screaming shack in advance to call for rescue.

And tomorrow Friday morning is his first Defence Against the Dark Arts class of the semester, and he'll have to plan out how he's going to fight Umbridge tomorrow.

Let him go to confinement? Just kidding, Zhang Xu doesn't have that leisure.
