Huang Zicheng on the stage was full of passion, while Zhu Yunwen off the stage shook his head when he heard it, but Zhu Yunyu next to him was only bored. He thought about the Japanese knife sent by Li Jie today. Unexpectedly, the Japanese knife was still very good. Unfortunately, he had not played with it for a few times before class. Now the Japanese knife could only be put aside. He was obviously close to him but he didn't dare to touch it, which made Zhu Yunyu feel itchy.

But at this moment, suddenly there was a heavy footsteps coming from outside. Then, the fat Zhu Biao rushed in with anger. Huang Zicheng also stopped to salute Zhu Biao.

Zhu Biao waved his hand at Huang Zicheng, then looked at Zhu Yunxiu and asked loudly, "Where is Li Jie?"

"Li Bandu hasn't come. Didn't he go to the emperor's grandfather?" Zhu Yunxiu replied for a moment. Li Jie entered the palace and just sent a gift, but the person did not come here.

"Didn't come? Hide quickly, come with me to find him!" Zhu Biao pointed at Zhu Yunxiu and said, "If you don't ask Li Jie, he can't swallow his breath."

Zhu Yunxiu was also wondering why his father was so angry. He seemed to be coming for Li Jie. However, he was bored when he listened to the class, so he immediately jumped up and said, "No problem, father, why are you looking for Li Fan to read?"

"Don't worry about this, I have to check with him today!" Zhu Biao was so angry that he felt annoyed when he thought of the weight loss plan. This was the gift his son-in-law gave him. If he had known this, he would not have agreed to let him marry Yuning no matter what.

Zhu Yunxi was even more curious when he heard this. This was the first time he saw his father get so angry, and it was because of Li Jie? In theory, with Li Jie's shrewdness, he shouldn't make his father so angry, right?

Li Jie was not in the palace, and Zhu Biao took Zhu Yunyu out of the palace in anger, preparing to go to Li Jie's house to find him. Zhu Biao was really angry and had to ask Li Jie for an explanation no matter what.

However, while on the road, Zhu Yunyu looked up at the sky, and then suggested to Zhu Biao: "Father, it's already noon now, and Li Bandu shouldn't be at home, but I know he might go to another place."

"You lead the way. Even if he hides to the ends of the world today, he will find him out!" Zhu Biao said angrily again. When he met Li Jie in front of the warm-up door, he felt something was wrong with the other party. Now he thought that he should be guilty, so he deliberately hid himself.

Zhu Yunqi immediately reported a place to the guards outside the carriage, and their carriage immediately turned, left Xishuimen and came to the Qinhuai River. Not far from the small courtyard where Li Jie lived, there was a quiet courtyard located on the riverside.

When the carriage arrived at the gate of the courtyard, Zhu Biao jumped out of the car and looked up. He saw a plaque "Quozhen Academy" hanging on the gate, which made him immediately realize that the Fengzhen Academy, which had been turbulent among scholars recently, was here.

"Father, let's go in. Class should be about to begin inside!" Zhu Yunxiu looked at the empty courtyard and immediately said, because he knew that there would be no one in the yard only during class, and everyone should have gone to attend the class.

"Is this Xu Zhen Academy created by Li Jie?" Zhu Biao did not rush in, but asked again. He was traveling in a coverall this time, and except for Zhu Yunyu, he only brought a few guards. He should be more cautious in terms of safety.

"It's not considered Li Bandu's work, but at first it was Li Bandu's lecture to me, but later the people from the Imperial Heavenly Prison went to listen to it, and the content of the lecture became richer. Finally, others also went on stage to give lectures. A few months ago, Li Bandu went to Japan, and the Imperial Heavenly Prison simply moved the lecture location here and established this truth-seeking academy." Zhu Yunxiu explained again.

"So you often come here every afternoon when you leave the palace?" Zhu Biao asked again.

"Yes, I'm here most of the time, and occasionally I go to Tiechejun to make a move. When Li Ban came back, I heard him say that he wanted to come to Qiuzhen Academy to take a look. After all, he hasn't been here since he moved here." Zhu Yunsheng nodded and replied.

When Zhu Biao heard that his son often came here, he finally felt relieved, so he stepped into the Xu Zhen Academy. Zhu Yunqiu also helped him explain the situation in the academy. In fact, this academy is not big, it is just a two-entry house. It is said that it was donated by Yuan Jianzheng of the Imperial Heaven Supervisor. After all, more and more people are attending classes, and the hot air balloon workshop needs to be kept confidential, so he can only find another place to attend classes.

The living room of the house has been converted into a classroom. Unlike the place where Zhu Yunyu taught in the palace, this classroom is very large. There are long tables and chairs underneath, and a blackboard is hung on the stage. People who teach usually stand on the stage. While speaking, they can write what they say on the blackboard so that the listeners can understand.

When Zhu Biao came outside the classroom, he immediately heard the noise coming from inside. It seemed that class had not started yet. When he walked to the window, he saw that the class was filled with people. Many people were still discussing something excitedly, and the expression on his face was quite excited.

By chance, just as Zhu Biao came out of the window, he saw someone walking out of the classroom. It was Li Jie who was looking for. This made Zhu Biao outside the window immediately angry. He took a step and wanted to break in, and then scolded Li Jie.

However, what Zhu Biao did not expect was that as soon as Li Jie came in, the noisy classroom suddenly became quiet. Hundreds of pairs of eyes looked at Li Jie, and there was a little respect in his excitement, which made Zhu Biao stop suddenly. After all, the classroom was so quiet, and he was really embarrassed to break in.

Li Jie walked up to the podium very naturally, then glanced at the person who was listening to the class, then cleared his throat and said, "Today we will talk about a class related to medicine!"

After Li Jie finished speaking, he picked up the homemade chalk next to him, then turned his head and wrote eight big words "The impact of obesity on the body" on the blackboard behind him. This made Zhu Biao outside the window stunned again. Is this Li Jie intentional?

"Father, we're starting to give a lecture. Let's go in and listen!" Zhu Yunxiu pulled Zhu Biao into the classroom at this time, and then found a corner behind him to sit down.

At this time, Li Jie on the stage said: "Obacteria is not a common problem, it mainly occurs in a few rich people, so there is little research in this regard in medicine. However, I believe that with the improvement of living standards, obesity will definitely become a problem that will bother many people in the future. Today I will talk about the various effects that obesity may bring..."

Li Jie did not seem to have seen the arrival of Zhu Biao and his son, but talked about the various effects of obesity on the body, and of course it was also interspersed with some basic medical knowledge from later generations.

Li Jie has already had a lot of experience in the lectures. Even if it involves some knowledge from later generations, he can explain it in a simple and easy-to-understand way, even if people without any foundation can understand it. What's more, for scholars, most of them have read a few medical books and are not ignorant of medicine. Moreover, what Li Jie said today is quite novel, so most people also listen with relish.

Zhu Biao came with anger, but with Li Jie's explanation, the anger in his heart disappeared without realizing it, and his waistline couldn't help but straighten, because the content of Li Jie's speech was related to him, and he even had personal experiences in many aspects, such as dizziness, physical weakness caused by obesity, especially poor breathing during sleep, and sometimes even wake up.

Zhu Biao never told outsiders about these physical problems. Some of them were not even known to the imperial physicians, but Li Jie talked about them. It was the first time that Zhu Biao knew about them. It turned out that these problems were all caused by obesity, which made him finally realize his father's painstaking efforts and he was only grateful to Li Jie in his heart.

After a class was finished, Li Jie was about to pack up and step down, but unexpectedly someone stood up and said, "Li Bandu, I heard that you have just returned from Japan and Goryeo. Can you tell us about the situation there?"

This person's words also aroused the approval of many people. Goryeo will not talk about it. Japan has always been the overseas country that Ming people pay the most attention to because of the Japanese pirates. Although Li Jie's action to Japan is a secret, many people still know it. So they also want to know what Li Jie did in Japan. What is the difference between Japan and the Ming Dynasty? Why are there so many Japanese pirates?

Hearing that someone was interested in overseas affairs, Li Jie immediately stopped and smiled: "Okay, since you want to hear it, I will talk about it. Speaking of the history of the exchange between Japan and the Central Plains, you may know better than me. Then I will talk about the origin and history of Japan, as well as the current situation of Japan..."

Li Jie said that he started with the myth of Japan, and then talked about the fact that Xu Fu might have crossed the sea to reach Japan. Finally, he began to talk about the history of Japan and the current battle between the Southern and Southern Dynasties of Japan, which is also the direct reason for the emergence of Japanese pirates.

However, Li Jie said everything he should have said, but he did not mention some of the things he shouldn't have said, such as the reason why he went to Japan this time, as well as the plans of Zhang Dingbian and others in Japan, etc., these are not convenient to talk about for the time being. Maybe the news will only be heard when the situation stabilizes in the future.

Zhu Biao in the audience also listened very seriously. He had collected a lot of information about Japan before, but it was not as comprehensive as Li Jie said, and he knew more than others, so he also had a deeper understanding of Li Jie's words. In the end, he couldn't help but sigh, no wonder Li Jie designed a plan for Japan, and it turned out that he knew Japan so well.

"Father, how do you think Li Bandu is talking about?" At this moment, Zhu Yunqiu next to him suddenly smiled and leaned into Zhu Biao's ear and asked in a low voice.
