Zhang Xu is very glad to have brought Professor McGonagall here today, if Professor McGonagall hadn't come forward to solve this matter, the ghost knows what would have become of his innocence.

Less than ten minutes after the Pettier sisters left, there was another knock on the door of Zhang Xu's dormitory.

This time it was Harry Potter and a group of four people who came in.

After seeing Harry take out the old textbook, Zhang Xu knew what they were looking for him.

"Well, do you have any potions questions for me?" Zhang Xu asked knowingly.

Harry flipped through the textbook, placed it on the coffee table, and then pointed to the notes on the side page and asked, "Zhang, did you write some of the notes here?" ”

Zhang Xu glanced at the line that Harry pointed to, "Using a pressure cooker to heat can reduce the heating time by about 75%", then nodded and said, "That's right, I wrote some of it." ”

"Sure enough, it's you!" Harry shouted in surprise.

"It's me, what's wrong?" Zhang Xu asked curiously.

"Thank you!" Harry said to Zhang Xu, "If it weren't for your help, I wouldn't have been rewarded by Professor Slughorn today. ”

"I didn't help much with today's Living Hell Potion," Zhang Xu said with a wave of his hand, "I think the other person who took notes in the book will be of more help to you." ”

"Do you know who the other person is?" Ron asked expectantly.

"I don't know." Zhang Xu shook his head and said, "I stumbled upon this Advanced Potions Making after I got Professor Snape's permission to look through the old textbooks in the classroom. ”

"When I found the notes above, I also asked Professor Snape who the book used to be."

When Harry heard Snape's name, the corners of his mouth twitched.

Zhang Xu didn't see it, and continued: "After reading this textbook, Professor Snape said that he didn't know which student's textbook was before, but he only knew that judging from the notes on the book, this student should be a genius in potions!" ”

Back then, Zhang Xu asked Snape about this question with the idea of making trouble, but he was confused by Snape's boasting.

"In that sense, you're a genius in potions." Ron looked at Zhang Xu with envy and said.

"I'm not a genius." Zhang Xu said, "In Potions, I just got the light of my family's inheritance. ”

At this moment, the dormitory was pushed open, and someone walked into the dormitory.

"But you're also strong in other ways," Ron continued enviously, "and you've always been great at Transfiguration and Charms. ”

"That's because you didn't see how much he was sweating in a place where no one was around." Zhang Qiu, who had just walked into the dormitory, said after listening to Ron's words.

"Since he was in first grade, he has been running to the Room of Requirement almost every night to practice spells, and then running to the kitchen every night when he is exhausted to get food."

"It took me a lot of effort to follow him and find out why he had to leave the common room every night and go on a date with a girl."

"It's all a thing of the past, auntie." Zhang Xu said to Zhang Qiu, who had just walked in.

I saw Zhang Qiu holding a thermos flask and putting it beside Zhang Xu, and then said, "This is your medicine tonight, remember to drink it on time." ”

Harry, it was the first time they had heard this in years, and they were a little surprised.

After all, when they were in the first grade, Harry's trio and Zhang Xu were not very familiar with each other, and when Harry and they went to brush up on Quirrell's copy, they didn't even think about calling Zhang Xu.

"Zhang, how did you become so strong now?" Ron asked.

"Just don't be afraid of death." Zhang Xu said, "Actually, my strength is not as exaggerated as you imagined, it's just that I'm not afraid of death in battle." When you are not afraid of death, people will become calm, so you can use your brain to fight, so that you can play your best in battle. ”

At this moment, a paper crane flying in from the window of the living room and landed in front of Zhang Xu.

Zhang Xu opened it and looked at it, and then replied.

After replying to the letter, Zhang Xu picked up the medicine that Zhang Qiu had brought just now and drank it in a few sips.

Although Harry and the others still had a lot of questions to ask Zhang Xu, they saw that Zhang Xu was drinking the medicine Zhang Qiu had just brought before they remembered that Zhang Xu was still half a patient. So they greeted Shanren, and Zhang Xu asked them to pack up all the Indian snacks they had just prepared for the twin sisters and take them away.

The twin sisters were so preoccupied just now that they weren't in the mood to eat dim sum, and Zhang Xu and Professor McGonagall were a little reluctant to drink the overly sweet Indian dim sum, so they cheapened Harry and them.

"I'm sorry for you." Zhang Xu said to Zhang Qiu.

The medicine that Zhang Xu drank just now was made with Zhang Qiu's help, and the prescriptions and medicinal materials were all brought from China, and Zhang Xu's family troubled Zhang Qiu to urge Zhang Xu to drink the medicine on time every day.

As the saying goes, the taste of good medicine is better than Laoshan white flower snake grass water, but Zhang Xu is sometimes a person like a child who would rather get sick slowly than drink medicine, so there are some things that can only be asked to Zhang Qiu.

"How are you doing?" Zhang Qiu asked with some concern.

"It's basically fine." Zhang Xu said, "Except for some insomnia and palpitations, there are basically no other problems." ”

"Then don't be tired." Zhang Qiu said to Zhang Xu.

Zhang Xu nodded yes, and Zhang Qiu sat for a while before leaving.

After Zhang Qiu left, Zhang Xu walked into the study, sat at the desk, picked up a copy of "Tianli 38 Sets of Physics" next to him and began to brush the questions.

Now there is not much time left for Zhang Xu, and in ten months, Zhang Xu will face the college entrance examination that is more terrible than Voldemort!

In the face of Voldemort, he can still run, but in front of the college entrance examination, Zhang Xu can't run away no matter what.

For so many years, Zhang Xu has been relying on self-study and eating old books to prepare for the college entrance examination, but at present, it seems that the situation is not optimistic, the magic class is not a big problem, but the problem faced by the cultural class is not small, he brushed this year's college entrance examination questions during the summer vacation, and as a result, he found that if he didn't hurry up, he would overturn next year.

Zhang Xu resigned as acting professor this year, so he didn't take the opportunity to get rid of his burden, travel lightly, and go all out to prepare for the college entrance examination.

Zhang Xu is ready to give up the Hogwarts course this year to give up the car to protect the coach, anyway, the pot of declining grades can be thrown on Voldemort's head.

In the foreseeable next ten months, Zhang Xu will be the most bitter protagonist of all Harry Potter fandom.

At ten o'clock in the evening, after Zhang Xu finished brushing a set of questions, he stretched and left the study and walked to the bedroom.

Coming to the balcony of the bedroom, there was already someone waiting for him.
