With the official turn with Dumbledore, Zhang Cheng immediately felt the hostility everywhere after returning to school.

Both Snape, who had a very bad relationship before, and other professors who maintained a neutral attitude on weekdays, took an isolated attitude, and even didn\'t even call when they met.

Maybe someone else will have complex psychological changes, or even can\'t stand such a living environment and resign voluntarily.

Unfortunately, Zhang Chenggen didn\'t care about this. Instead, he encouraged his two students, Harry Potter and Draco Malfoy, to show their talents and establish a high prestige among the students.

After all, Hogwarts is a magic school. The most important thing is not the professors at all, but the students who are known as the future of British magic.

As long as we can handle them, we can influence the attitude of the parents behind them, so as to change the attitude of public opinion and the bureaucrats of the Ministry of magic.

That\'s why Lido couldn\'t wait to decline to be the Minister of magic and hid here as the principal for half a century.

Fortunately, this bloodless fight lasted only more than a month and declared a truce.

Of course, not because the contradiction between the two sides has been alleviated, but because the whole semester is over, all students take the express train home and enjoy a relaxed and pleasant summer vacation.

Due to his disgust with the Dursleys, Harry Potter did not return to the home where he had lived for 12 years. Instead, he chose to accept Draco\'s invitation and spend the whole holiday at Malfoy Manor.

I have to say, this is full of irony, and it also makes Albus Dumbledore angry.

Not long ago, Lucius, through his excellent political skills, united with the school board and officials of the Ministry of magic, severely restricted his rights as president, especially weakened the power of personnel appointment and financial control.

While the old man was busy soothing the uneasiness of the professors and dealing with the messy affairs in the school, Zhang Cheng easily got rid of the small tail behind him, went directly to the door of a seemingly ordinary house, raised his hand and knocked on the door.

Bang! Bang! Bang!

After a few knocks on the wood, a 34 year old white woman opened the door and asked in a polite voice, "Hello, sir, can I help you?"

"Ah! Hello, Mrs. Granger. I\'m Hermione\'s professor. Is she at home now?" Zhang Cheng bowed politely to show his intention.

"Professor?!" the woman was stunned at first, followed by a quick reaction and covered her mouth in surprise. "Oh - my God! You... You\'re a wizard? Sorry, please come in. Hermione\'s upstairs."

"Thank you very much!" Zhang Cheng said politely and walked into the house full of British style.

But before he could sit down, Hermione\'s mother shouted at the top of her voice, "Granger! Come down! A professor at school is looking for you!"

"What... What?!"

The girl in a casual T-shirt and Cowboy SHORTS quickly ran down the stairs.

When she saw who it was, her pupils contracted suddenly.

After all, she still remembers what happened in the tree hole more than a month ago, and even has nightmares occasionally.

"It seems that you had a good holiday. How\'s it going? Would you mind talking to me alone?" asked Zhang Cheng with a smile.

Hermione hesitated obviously, and finally nodded her head gently: "OK!"

"Let\'s talk. I\'ll go out for a walk and come back in half an hour."

Seeing this, her mother immediately picked up a coat and planned to go out for a walk to make room for their privacy.

Seeing her mother go away, the girl raised her head and asked in an uncertain tone, "Professor, what do you want to talk to me first?"

"It\'s very simple. I hope you can join my camp like Harry. In return, I can teach you to learn the profound magic knowledge that Hogwarts will never learn, and protect your parents from being hurt in the future war." Zhang Cheng said his conditions without any disguise.

Because with the in-depth study of creativity, he increasingly felt that he needed an assistant.

Harry Potter and Draco Malfoy obviously don\'t have this talent, so he can only target miss "know it all".

Judging from her academic achievements, Hermione has excellent theoretical and research talents and is an almost perfect candidate.

"War?!" the girl widened her eyes in surprise, as if she couldn\'t believe that she would hear such a terrible word from a professor.

"Yes! War! War in the magic world!" Zhang Cheng gave a straight answer in the affirmative. "You should know that the history of mankind is a history of war, especially the war in the magic world, which has never stopped from the beginning to the end. In particular, the ambitious Voldemort has not really died. He is planning to return and start a new war. At that time, the British magic world will be divided into two, either join Dumbledore to fight Voldemort, or add The fallen demons set off a revolution, destroy everything and establish a new order. Only I am qualified to protect some people with a neutral attitude. "

"Why did you say this to me? What\'s your purpose?" Hermione undoubtedly knew the dark scenes behind them for the first time and shivered with fear.

"I need you! To be exact, you need your talent to help me complete a great research. In addition, do you have the heart to watch your parents die of murder, or to avoid danger, erase their memories once and for all, and immerse yourself in pain for the rest of your life? Choose, Miss Granger, which will determine your future destiny." A silver light flashed in Zhang Cheng\'s pupil and began to exert influence on each other\'s brain through his spiritual power.

In just a few seconds, Hermione seemed to see the desolate scene of separation from her parents in the future and couldn\'t help crying.

After returning to reality, she quickly wiped her tears, bit her lower lip and replied in a decisive tone: "no! I will never let that happen! I promise your terms, professor."

"Great! I promise you won\'t regret your choice. Here, I have an experimental data. Your first task is to find fuzzy rules from the chaotic results. As long as you finish this task before the beginning of school, I will give you two amulets, which are enough to protect the wearer\'s life."

After that, Zhang Cheng stood up, took out a tissue paper, gently wiped the girl\'s tears, and then left a thick note to cast the transmission magic and disappeared in place.

He knew very well that as long as he opened the experimental note, Hermione would be firmly attracted by the content.

Curiosity and exploring the unknown are human nature. Some people are particularly obvious in this regard. Miss "know it all" is one of them.
