There is only one class in the school every day. Today is mathematics, and I only talked about it for one hour. The rest of the time is allocated by these preparatory disciples themselves.

After all, the Tianyuan Sect still focuses on cultivating immortals, and most disciples still focus on cultivation. As for those who are eliminated from the roots like Jiang Cheng, if they want to enter the lower court and become an outer disciple by relying on their own knowledge, they can only learn by themselves.

It was fine. After Qin Song left with a group of disciples, Jiang Cheng took out another book from his desk. This was the mathematics taught in the second year after entering Tianyuan Sect. The content in this book was obviously much deeper than the basic mathematics.

"In complex math operations, this book can provide the host with 50 points of academic master's points and 500 math experience."

In my mind, the academic master system identified the book.

"So much?" Jiang Cheng was slightly happy, but then he was a little worried. Although the basic calculations were not given much before, they were just enough for him to upgrade, but this one was obviously not enough.

The upgrades of this ghost system are calculated in decimal system. The experience required for each level is ten times that of the previous level. I really don’t know if these knowledge has an end. Jiang Cheng simply calculated it. If he calculated it up by ten times, the experience required for upgrading at level seven is 100 million. Just thinking about it, Jiang Cheng felt a little guilty.

This is just a mathematical technique. If he wants to become a comprehensive academic master, Jiang Cheng doesn’t know how long it will take to achieve it.

After feeling a little, Jiang Cheng continued to read books, and began to list some knowledge points according to the previous method, and then listed the corresponding questions on the straw paper.

This practice was taught by a scholar-master in his previous life. Unfortunately, Jiang Cheng rarely studied like this before. Now he has a system of academic masters. Although this system seems a bit low in Jiang Cheng's opinion, it also gives Jiang Cheng the motivation to learn.

In fact, sometimes, people do not want to work hard, but do not have a direction of hard work. Learning is a matter that is difficult to achieve results in a short period of time. However, people’s inferiority is greed, including in doing things. I hope that if I work hard, I will see the results soon. This is also the reason why many people in their previous lives are obsessed with online games and cannot extricate themselves.

Because even if the results are not obtained immediately, the little bit of experience can be seen. Jiang Cheng is in this state today. Although it is boring, he still tries hard to calm down and follow this method to list things he doesn't understand bit by bit, and then understand and absorb bit by bit.

I don’t know if it’s the system, but in short, Jiang Cheng was very dedicated to learning, and even Bai Zhirou appeared behind him for a long time and didn’t notice it.

Bai Zhirou is a teacher who teaches mathematics. It is actually quite easy here. She only teaches her homework every week, and she practices the rest of the time.

When it was getting dark, Bai Zhirou came back and something fell here today.

Is there anyone in the school?

When Bai Zhirou saw the figure with her back facing her, she was a little surprised. You should know that even among those preparatory disciples who had insufficient bones, most of them would choose formations, weapon refining or medicine related to cultivation, such as mathematics techniques... Since she hasn't seen a few people who are willing to study them seriously.

Especially when he saw that the other party was Jiang Cheng, Bai Zhirou almost thought she had hallucinations.

She had a deep impression of Jiang Cheng, not because of how outstanding the other party was, but because she had seen someone as unprofitable as Jiang Cheng for so many years in the Tianyuan Sect.

It would be fine if you practice without roots and bones. After finally getting into the immortal fate, you didn’t even have the idea of ​​working hard. You gathered a group of people all day long to do all kinds of things that Bai Zhirou thought were childish and boring. Yan Cheng was the first person who could make him die.

Thinking of Yan Cheng's words before, Bai Zhirou sighed, and regardless of what medicine Jiang Cheng took, she went straight to the podium to retrieve her things. What surprised her was that Jiang Cheng didn't look up at this side.

With Bai Zhirou's eyesight, it was obvious that Jiang Cheng had really been involved at a glance. This made Bai Zhirou curious and couldn't help but stand behind Jiang Cheng and look at his straw paper carefully. It was a compound algorithm. This was what he had explained the year before and had already finished it.

But it’s right to think about it. Judging from Jiang Cheng’s usual performance, even if he wants to cheer up, what he is talking about now is probably too difficult for Jiang Cheng.

Is the prodigal son looking back?

Bai Zhirou sighed in her heart. It was still too late to have only half a year left.

"Teacher Bai?" Jiang Chengzheng looked at the question in front of him with distress, and suddenly saw the shadow on the table, which scared him. When he turned his head to see Bai Zhirou, he breathed a sigh of relief and said a little dissatisfied: "Can you bring some noise when you walk next time? I'm scared to death!"

Bai Zhirou is very beautiful. Tianyuan Sect is a sect of cultivation. The most deficient thing in the sect is handsome men and beautiful women. It is not necessary to say that they are good-looking in such a place, but Jiang Cheng has a very stable mentality in facing this beauty.

The two are not from the same world. Bai Zhirou is about to enter the Qi training period, and it is possible to enter the foundation-building realm in the future. Once he reaches the foundation-building realm, his life span will increase greatly, and it is not difficult to officially win the immortal fate. Jiang Cheng will probably spend his life in a daze in the future. The distance between the two is like clouds and it is impossible to get together. Therefore, even if a noble young man like Qin Song can't speak completely in front of Bai Zhirou, Jiang Cheng was very calm when facing Bai Zhirou.

She is not worthy of herself, so why bother with her?

Nothing wrong.

"You are too involved." Bai Zhirou glared at Jiang Cheng angrily, but she did not deliberately restrain her breath.

"It's just right, please help me see these questions." Jiang Cheng didn't think much about it and handed the questions on the straw paper to Bai Zhirou.

Really...not polite at all!

Bai Zhirou shook her head, but was not angry. The student was studious, which was a good thing for her teacher who was temporarily arranged, although she didn't have much hope for Jiang Cheng.

"Is this... you found it yourself?" After a while, Bai Zhirou looked up and looked at Jiang Cheng with surprise. It was not that it was so difficult, but that Jiang Cheng had basically found all the more profound topics in this book.

"Yes." Jiang Cheng couldn't wait to stand up and pulled Bai Zhirou to sit down: "Come on, teacher, tell me quickly. Why do I feel a little like practicing Qi? "

"Magic techniques are not as simple as simple calculations. Any knowledge that reaches a certain level will lead to the same destination." Bai Zhirou nodded: "Three-part Guiyuan is the side branch in Guiyuan algorithm, in the mathematics..."

Bai Zhirou’s speech was very complicated, but Jiang Cheng listened very carefully. Many things that were not recorded in the book were understood at this moment, and she felt enlightened.

"Teacher, stop talking!" Before Bai Zhirou could speak halfway, Jiang Cheng suddenly interrupted Bai Zhiru and said, "I probably understand. I'll calculate it, right?"

After saying that, without waiting for Bai Zhirou to answer, he quickly picked up the pen and wrote it on the straw paper. The obscure things before were slashed, but after Bai Zhirou pulled it a little, he felt like he was seeing the sun. After finishing the question in one breath, Jiang Cheng continued to calculate the next question without stopping. After Bai Zhirou's surprised gaze, he calculated five paths in a row, and then he was stuck in the sixth path.

Looking at Jiang Cheng who was frowning and thinking, Bai Zhirou was a little surprised. She found that this young man was not as rotten as he imagined. Instead, he had the keenness that ordinary people did not have in mathematics, and could even understand the same.

Have you learned it?

Bai Zhirou did not give advice. She watched Jiang Cheng's difficult calculations step by step. Every time she figured out a key, she would express an excited expression. This expression could not be pretended.

She didn't leave either, but just watched quietly until Jiang Cheng couldn't help but solve the tenth question. When she looked up, she showed a gratified smile on her face.

"Teacher, why are you still here?"

Bai Zhirou: "..."

"Uh... no, I mean, it's great that you're still here, teacher, tell me about this question!" Jiang Cheng saw that Bai Zhirou's expression was wrong, and quickly changed his words.

The bloated chest fluctuated violently for a few times before suppressing the stuffy breath in my chest.

"This is a derivative diagram of the River Map..."

Jiang Cheng, who taught and learned one by one, was immersed in the pleasure of solving problems, did not notice the passage of time at all. Until the last problem was solved, it was already early in the morning.

"Ding~ The host has received guidance from experts. In addition to the 50 academic master points and 500 digital art experience obtained in this book, he will receive an additional bonus for experts, including 10 academic master points and 100 mathematics experience."

The system prompt made Jiang Cheng stunned, then looked at Bai Zhirou, with a hint of excitement flashing in her eyes, and she solemnly bowed to Bai Zhirou: "Thank you, Teacher Bai."

"It's getting late, go back and rest." Bai Zhirou was still very satisfied with her disciple's performance.
