When Harry Potter opened his eyes, he saw the familiar ceiling, and the sun shone right on his face when he saw that it was already noon.

Not long after he went to bed last night, he noticed that the scar on his head was getting more and more painful, so much so that he rolled out of bed and woke Ron and them.

Immediately afterwards, the magic in his body began to be out of his control, and then the whole body of the person became hot.

Then his consciousness became more and more blurred, but he did not lose consciousness completely.

It was as if he had been carried to the school infirmary by Ron and Neville, and then he felt a little cooler, and there seemed to be a lot of people around him discussing something.

Before finally losing consciousness, it was as if a small snake had crawled through its nose and into its stomach through its throat.

Harry was aching all over, and when he tried to reach out to block the sunlight that was shining directly into his eyes, he found himself tied to the hospital bed with ropes and couldn't move.

"Who are you?"

A voice came from the bedside.

Harry turned his head and saw Zhang Xu sitting behind a table far from the hospital bed, cutting steak with a wand in one hand and forking the cut steak into his mouth with the other.

On the table, in addition to the steak plate and water glass, there seemed to be a Muggle gun.

Harry, who didn't wear glasses, couldn't see very clearly.

"I'm Harry, Zhang!" Harry, tied to the bed, shouted, "I'm Harry Potter, your classmate!" What's going on? ”

"Then you say something that only you and I know." Zhang Xu said.

Harry thought for a moment and said, "I saw you and ...... as I passed by the professor's bathroom on Wednesday night."

"Ahem...... "Ahem," Zhang Xu coughed twice and said, "I'm discussing with Peeves how to make trouble for someone, don't tell anyone else, the impact is not good, change things." ”

Harry reacted instantly, shut up immediately, and then added, "At the end of last semester, you gave me a wand to use in case of an accident during the summer vacation, and then when you got off the train, you said that you were afraid that the wand would not suit me, and you gave me another wand. And you didn't give me chopsticks when you sent me food during the summer vacation. ”

For a while, although Harry didn't know what Zhang Xu was going to do, he still answered honestly.

"What is the fourth power of the cube of x multiplied by the fifth power of x?"

"You fly for 10 seconds on a broomstick at an elevation angle of 30 ° at a speed of 10 meters per second, so how far do you fly in the horizontal and vertical directions?"

"Knowing the function f(X)=sinXtanX, then is this function odd or even, what is the minimum positive period of the function, and which line is symmetrical about the function image?"

In the end, Zhang Xu gave Harry a few more math problems in a row.

Yesterday, Harry's scar hurt before his magic went berserk, and Zhang Xu was very worried that Voldemort was doing the ghost, for fear that the current Harry had been controlled by Voldemort, and even taken away, so he would come up with all kinds of questions to confirm his identity.

Zhang Xu can be sure that Voldemort has not learned trigonometric functions, functions, etc., and even if he robs Harry's memory, he will not be able to make these math problems at once.

Harry, who had a black line on his head, now realized Zhang Xu's intentions, and he could only answer Zhang Xu's questions honestly, in order to confirm that he was the genuine, innocent, and fake Harry Potter as soon as possible.

When Harry answered all the questions, Zhang Xu breathed a sigh of relief.

Seeing Zhang Xu breathe a sigh of relief, Harry himself relaxed.

Harry was speechless at the moment, he had given up his resistance and let Zhang Xu toss.

"Alright, let's move on to the final step." Zhang Xu said, "Please shout 'Tom Riddle is a half-blood wizard' ten times." ”

Harry:......

After being cleared of suspicion of being possessed by Voldemort, Zhang Xu released the rope that bound Harry.

The professors, who had been watching the room through the two-way mirror in Madam Pomfrey's office next to it, arrived in the room and began to give Harry a full examination.

After Zhang Xu went to the kitchen to bring back lunch for Harry, he skillfully went to the medicine cabinet and took the medicine to deal with the wound on his calf that was kicked by Peeves.

After making sure that Harry was not cursed because of the unicorn's blood, the professors, including Zhang Xu, breathed a sigh of relief.

After asking Harry the reason for the sudden mana riot last night, the professors dispersed.

Everyone hasn't closed their eyes since last night.

Zhang Xu did not go back to the dormitory of the Eagle Academy, but returned to his professor's dormitory, and went to bed after taking a hot bath.

When Zhang Xu woke up, it was already eight o'clock in the evening.

When I went to the kitchen, I found that there were many students chatting while eating.

When Zhang Xu walked in, everyone greeted him one after another.

Zhang Xu asked the house-elf to bring a dinner, and then chatted with a few classmates.

The biggest news of the day today wasn't that Harry had been in the school infirmary last night, and that many of the students who had gone to the maze over the weekend had returned in vain.

The triwizard tournament's maze was opened to the public after adjusting the difficulty, and during the summer vacation, the Sphinx, who was so tired that he worked in it, demanded that his salary be doubled.

After the start of school, there are no foreign tourists, and it is the turn of the students to brush up on the copies.

It wasn't hard for the students to see the warriors weave the maze last semester, but when they got in, they realized that they had grown up.

For a whole day, not a single student made it to the end of the maze.

Ron, on the other hand, was in no mood to get involved because he was worried about Harry.

Zhang Xu left the kitchen after eating and drinking.

When Zhang Xu came to the foyer to take a walk outside, he saw Snape hurrying into the castle.

Before Zhang Xu could speak, Snape came over and asked, "How's Potter doing?" ”

"Last night Harry suddenly had a magical riot for no apparent reason, and the situation was critical." Zhang Xu sighed and continued, "Later, I could only go to the Forbidden Forest to find the unicorn and use the unicorn's blood to clear the negative state on his body. After taking the unicorn's blood, Harry is now fine. ”

Listening to what Zhang Xu said, Snape's eyes widened in disbelief.

As a Potions professor, he knew the consequences of drinking unicorn blood.

After Zhang Xu said, "Harry is in the school infirmary now", Snape hurried to the school infirmary.

Zhang Xu didn't follow up to see the excitement, when Snape knew that Harry was not cursed, he would definitely have to fight Zhang Xu who didn't speak clearly, he wasn't in the mood to cause trouble.

Tonight a lot of students were playing outside the castle, and there was no quiet place to walk around the lake.

Footprints were strewn around the beating willows, and a group of people were screaming at the shack party.

Zhang Xu thought about it and simply walked towards the Forbidden Forest.
