Liu Chan walked into the classroom, and the people sitting in the front were naturally those from the Mojia family in Chengdu who had not left the house, and Yu Dan, he found that he was sitting in the back, presumably he came on time, and he could only sit there after he came.

To his surprise, Ma Jun also rushed back!

"This guy, has he completed his mission?"

Although he was surprised in his heart, he didn't say much, the time had come, and the time for teaching had already begun.

"The content of today's lecture is the foundation of experimentation." He cleared his throat, and after returning the discipleship of his "students", he officially began to lecture, "The so-called experimental science is to use certain artificial means to actively intervene or control the occurrence and development process of research objects according to the purpose of research......

"And the variable is ......"

"In this lesson, we will elaborate on the design of experiments and the selection and control of variables......"

A series of novel but professional words kept coming out of Liu Chan's mouth and entering Yu Dan's ears.

Knowledge across the ages is destined to be incomprehensible, and Yu Dan's reaction at this time is exactly like this, around Liu Chan spoke wildly, and still the eight winds did not move, because the shock and whirlpool in his mind had made him unable to find the north.

He is not a fool, and although it is difficult to understand, it does not mean that it is completely incomprehensible. Those theories that seem to be understood or not have already shocked him.

In Yu Dan's view, this can not only be applied to the basic manufacturing of papermaking, but also can be integrated into the governance of a country, self-cultivation and self-cultivation to govern the country and level the world!

After listening to a class, although everyone frowned, and felt deeply rewarded by Liu Chan's lesson, he was the one with the most huge mood fluctuations.

"Mr. Yu, do you know why I called you here?" Just as he was thinking, Liu Chan walked to his side.

In this class, in fact, a lot of theoretical knowledge Liu Chan has already talked about before, and now it is completely run through, on the one hand, so that those who have heard it can understand it, and on the other hand, it is to keep Yu Dan from being confused.

Finding Liu Chan's approach, Yu Dan's expression tightened, he stood up and bowed: "The wisdom of the young master is comparable to Haoyue, and a lecture will really wake up the contemptible people. ”

From the other party's words, Liu Chan heard emotions that he hadn't felt in his previous conversation.

That's respect from the bottom of my heart.

In the past, although Yu Dan was respectful in his words and deeds, it was not he Liu Chan who respected him, but the aura and identity attached to him. Although he bows his head, it is actually just a bow to power, and once he loses this layer of aura on his body in the future, then he will definitely abandon it.

But now, Liu Chan can be sure that this person has been completely subdued by him, and it is definitely much more reliable to convince people with talent, morality, and reason.

He turned to Ma Jun, who was standing on the side and waiting, and said, "Deheng, you go to the study and wait for me first." ”

After Ma Jun left, Liu Chan called Yu Dan and walked towards the Fuzhong Garden.

Along the way, Liu Chan didn't speak, he was waiting.

Sure enough, it didn't take long for Yu Dan to suddenly stop in a secluded place, and then knelt down in front of Liu Chan.

"The minister is guilty."

Liu Chan smiled, "What is the sin of Mr?" ”

Yu Dan said with a flushed face: "It is a crime for the minister to conceal his origin and not report it." ”

Liu Chan stepped forward and bent down to help him up, "Mr. Yu, I said earlier than you, I never force my subordinates to do things against their will, everything goes with the flow, follows their hearts, and acts like this, not guilty." ”

Yu Dan gritted his teeth when he heard this, but he broke free from Liu Chan's hands and knelt down again with a plop.

"Minister...... It is Hanchen, seeing that the country is harmed by traitors, but because of the cowardice of the heart and abandoning the official and fleeing, living in the wilderness and doing nothing, this crime is the world's scholars and sons to abandon it, the minister is afraid day and night, and now he has to meet the lord, and he deeply feels that the lord is virtuous and talented, and he is willing to report to the country and serve the world with the body of this guilty minister! ”

After saying that, he kowtowed heavily and buried himself deep in the ground.

His origin, to be honest, was something Liu Chan never expected. His previous considerations, at most, were that Yu Dan was originally an official of the Wei State, and even obstructed his cheap father's forces.

But I didn't expect it, but it wasn't like that at all.

The sentence he said, "Chenben Hanchen", is not a courtier of the Han family like the officials of the world say for fame and fortune, but it means that his identity is an old minister next to the Han Emperor at the end of the Han Dynasty! It does not belong to any powerful force, but only serves the emperor's own Hanchen!

At this time, Liu Chan understood why he was so proficient in the art of papermaking, and now it seems that he is likely to be an official of the craftsman office during the period of Emperor Biao before Dong Zhuo entered Luoyang.

Next, Liu Chan and Yu Dan asked and answered, and the former finally figured out Yu Dan's true identity.

It can only be said that Yu Dan was cowardly when he was young, although he was a talent, his talent was also excellent, and he worked in the craftsman's office. But limited to experience, I am still timid when encountering problems. After Dong Zhuo entered Beijing, he saw that several ministers of the court and the central government had died under his sword, and he was frightened, so he abandoned the official seal and fled overnight.

This escape is incognito, and there is no chance to re-enter the office.

In this regard, Liu Chan couldn't help but feel a little embarrassed, the mistakes of his youth have turned into stains and misfortunes in his life, which is really not worth it.

He helped Yu Dan up again, and this time the other party did not resist.

"Mr. Yu, let the past pass, everyone has a young age, this is not an unforgivable sin."

Hearing Liu Chan's words, Yu Dan's face recovered from gray to bloody, he also wanted to find a good lord to serve in his early years, but as long as he said his origin when he recommended himself, he would be laughed at. Now, he knows how rare it is to meet a lord who is willing to forgive him for his youthful cowardice and mistakes.

You must know that there is a saying in later generations that the nature of the country is easy to change and difficult to change, and at this time there is also this point of view, his behavior at that time can be regarded as running away from the master, such a character, who dares to accept it.

Looking at Yu Dan, who had regained his spirit, Liu Chan pondered for a moment, and said solemnly: "Although I don't care about this matter, I don't know how others think of you, how to act in the future, presumably Mr. has a plan." ”

Yu Dan heard this, and his heart was open.

He knew that accepting his lord regardless of his previous suspicions in front of him was making him prove that he was no longer the original person who ran away from his master.

He immediately responded, "Lord, the minister is brave in everything, saddle the horse before and after the lord, in order to serve the kindness of the encounter!" ”

This middle-aged man, but at this moment, finally paid off the mistakes he made when he was young......
