Fu Zhi walked out of the classroom with her phone in her hand and made a call through WeChat.

The call was soon picked up, and the moment she put her earphones on, a myriad of worried voices blared out.

"Did she get hacked?"

"I thought she had already forgotten about us!"

"Why isn't she speaking? I'm sure someone must have hacked into her phone!"

"But isn't she a hacker herself?"

"Well, it's not impossible for her to lose her touch sometimes, right?"

"Master? Are you there? If you're there, can you say something?"

"Shush, come one by one. Don't all talk at once," Fu Zhi said. She was in the restroom washing her hands right now.

The group fell silent. Then, after what felt like a century, Bai Ji's excited voice rang out. "Master, did you finally remember the password to your WeChat ID?"

While he was talking, there was a hint of sadness in his voice. "You've been ignoring me ever since I helped you settle the matter in the QQ group. Do you know how long it has been since the last time you gave us a lecture? It has been 3 years and 3 months!"

Fu Zhi turned off the tap and giggled. "It has been more than 3 years already?"

"Yes!" Bai Ji replied. "What are you doing in Yu City? Are you working on some kind of secret project? You should've told us so that we could lend you a hand."

"Nope. There's no secret project," Fu Zhi said. "I'm just attending school here and preparing to take on the college entrance examination."

Bai Ji was speechless.

'Hah. What a funny joke.'

Bai Ji did not know why but he felt like a maxed-level character wasting his or her time killing slime in the novice village.

"We won't force you if you don't want to tell us," Bai Ji said after he came around to his senses. "Anyway, what do you want us to do for you?"

"About that..." Fu Zhi said. She had already come out of the restroom, and as she walked down the corridor, she added calmly, "Tell He Ming and Chen Xin to pack their stuff and come to Yu City. The final examination is around the corner, and I need them to teach my classmates."

By the time Fu Zhi returned to her class, Song Fang, who had already recovered, was guiding the students in the class through organizing their notes for different subjects.

Self-help was always better than receiving help from other people. That was Song Fang's motto. Besides, there was a solution to every problem, so all they had to do was keep on trying.

The class session soon ended, and it was time for them to go home.

After Zhou Zihuai finished teaching his friends about a certain Physics question, he approached Fu Zhi with an exercise book in his hand and said, "Based on my observation, our class's weakest subject is Mathematics. I can score about 138 in a normal examination, but I've never scored more than 130 in the final examinations."

Fu Zhi was rummaging through the books in her drawer. There was a lot of stuff in her drawer, and most of it was just rubbish and whatnot.

When she heard Zhou Zihuai's voice, she threw a badge aside and replied, "Are the math questions of the final exams that difficult?"

It went without saying that those questions were a piece of cake for Fu Zhi, but it was not the same for Zhou Zihuai. "Do you know Hu Lei? The one who came back from Cambridge University? He was tasked to create the question paper for Mathematics, and that year was probably the year with the highest teenage suicide rate in our country."

He paused for a moment before adding, "Although the government has banned him from creating any more question papers, many teachers around the globe like to imitate him."

Fu Zhi tried to search for Hu Lei in her brain, but the name did not ring a bell.

'Maybe this Hu Lei dude was not my student?' With that thought in mind, Fu Zhi waved her hand and said, "It doesn't matter. Just stay on track and all of you will be fine."

At the same time, Director Liu successfully caught a couple on a date in the forest behind their school. After jotting down their names in his book, he harrumphed. "Tell your parents to come to school tomorrow! The final examination is just around the corner, and you two are still in the mood to see each other in the forest? You are such a disappointment!"

The couple shrank back and shivered in fear.

Director Liu took his scooter key from the office. After he nodded at the security guard, he hopped onto his beloved scooter.

At the same time, a black van appeared in front of the gate of the school. A man wearing a black trench coat then emerged from the van. He was wearing gold-rimmed spectacles and he had a gentle-looking face.

When Director Liu arrived at the gate of the school on his pink scooter, he pulled a pair of leather gloves out of his bag. While he was putting on the gloves, he caught something out of the corner of his eyes and felt stunned.

Since Ma Mingquan had to stay back to help his students in Class 21, he came out late as well.

Right now, Director Liu and his scooter were blocking Ma Mingquan's way.

"What's wrong, Director Liu? Why are you standing here?" Ma Mingquan asked.

However, Director Liu paid him no mind. It took him quite a long while before he finally came around to his senses. He smacked his lips and then turned his head around mechanically. When he saw Ma Mingquan, he thought for a while and waved at him. Then, he pitched his voice low and said, "Look over there. Does he look like Chen Xin to you?"

As one of the question setters for the college entrance examination, to some students, Chen Xin was the personification of "crazy", "mad", and "insane". Many students liked to scold him, but none of them actually paid attention to Chen Xin's private life, including what he looked like in person.

However, the teachers of No.1 High School were different. Although Yu City was not as big as the capital, it was still one of the biggest cities in their country. Two years ago, the Education Bureau had sent the director and some outstanding teachers of No.1 High School to attend Chen Xin's class in the capital.

That said, Ma Mingquan did not pay as much attention to Chen Xin because he was a Physics teacher and Chen Xin was a language teacher. Be that as it may, Xiao Liu was different. He was the director of No.1 High School, so he had to pay attention to everything.

Chen Xin had an ordinary look, but he had a scholarly aura about him that made him stand out from the crowd.

After hearing what Director Liu had said, Ma Mingquan squinted his eyes and studied Chen Xin from head to toe multiple times. "I don't know if he's Chen Xin or not, but he's not as good-looking as Fu Zhi or me. In short, he looks normal to me."

Director Liu did not know what he should say.

'Although Fu Zhi is a hateful brat, we don't have to insult her from time to time.'

That said, Director Liu was not very sure either because he had only seen Chen Xin once.

He was one of the question setters, so many elite schools in the capital wanted to invite Chen Xin to teach a class in their schools. They offered a lucrative amount of presents and gifts to Chen Xin, but he gave them the cold shoulder.

How was there any chance a bigshot like him would show up at No.1 High School in Yu City?

Director Liu felt that it was impossible, but what if a miracle had happened?

With that thought in his mind, Director Liu decided to take a photo of the man in front of him. However, just as he took his phone out, the man went back into the van and the van slowly vanished from their line of sight.

Chen Xin's flight was delayed, so by the time he made it to No.1 High School, Fu Zhi had already gone home. Therefore, when he got back into the van, he sent a text message to Fu Zhi and asked if she had time to come out to meet him.

However, Fu Zhi did not reply to him.

A few men in the van were staring at Chen Xin's phone, save for one person. He was leaning against the back of the car seat and he looked rather annoyed. He lifted the blanket from his body and asked coldly, "When will we start the class? I can't stay away from my experiment for too long."

Upon hearing his question, Chen Xin put his phone down and said, "Well, we have to inform the school so that they can prepare a proper venue for us, and then…"

"I don't care what you're going to do. It's none of my business!" Hu Lei interjected, his angular face filled with rage. "I only agreed to give 7 lessons to the students of No.1 High School because you promised me that you would introduce an excellent mathematician to me so that I can discuss mathematics with him. I hope you will keep your promise. Don't try to fool me with some useless buffoon, or you will face the consequences!"

The atmosphere in the van froze.

"Don't worry," Chen Xin replied, maintaining the same smile on his face. "I've contacted Mr. Ouyang, so he will prepare everything for us. If you are tired, why don't we take you back to the hotel so that you can get some rest first?"

Hu Lei nodded in frustration.

The van soon arrived at a 5-star hotel near No.1 High School.

Hu Lei pulled the door open and got out of the van without any hesitation, as if he could not bear to stay in the van for another minute.

As soon as the door was closed, Qian Man smacked his hand on his thigh and hissed, "What the hell is going on with him? Did you hear what he said just now, Chen Xin? He insulted our master! Why didn't you let me beat him? Besides, if it were not for him, we would not have missed our flight and we might be seeing our master right now. Does he really think he's better than all of us just because he studied overseas? Have I told the world that my master is Fu Zhi? No, right? In my opinion, we should ask our master to teach this dude some manners!"

"Calm down," Chen Xin said as he patted Qian Man's shoulder. "We should not bother our master so much. When the time comes, he will know the difference between him and our master."

"That would be best!"

The next day, in No.1 High School in Yu City...

Ever since a few classes had refused to lend their notes to Class 21, this matter had basically become an unspoken hot topic among everyone in the school.

Perhaps they all wanted Bai Ji and He Ming's exercise books from Class 1, but most of the students kept their distance from Class 21.

In the morning, Xiang Yusheng and Xu Tongtong went around the school to distribute the photocopied version of the exercise books to Class 3 to Class 18.

They all expressed their gratitude to them and said they would treat them to a meal one day.

When they were on their way back to Class 1, Xu Tongtong said with a big smile on her face, "This way, no one is going to help Class 21, and they will not be able to get notes from any classes. Not only that, but it will also be difficult for them to surpass Class 18 in the final examination now that all of us have the exercise books of Bai Ji and He Ming!"
