Ji Tang

Chapter 452 Purification
Zheng Ming finished his speech and stood aside, and Li Ke took the stage next.

Li Ke is different from Zheng Ming. The superiority of royal education is undoubtedly revealed at this moment!
First he bowed to the emperor and prime minister, then to the teachers and students, and finally bowed to Ji Song: "Students are ready!"

Ji Song nodded. In his opinion, Li Ke was superior to Li Shimin's other sons in terms of character and intelligence. Even the prince Li Chengqian was slightly inferior.

But things are often like this, and it’s not something you can just get into. There are too many things involved, and it can’t be explained clearly in a few words.

If there must be a reason, it can only be said that his life is not good!
The mother of the princess of the previous dynasty made him naturally ineligible for the throne of the Tang Dynasty.
Shaking his head not to think about this, he said directly: "Then let's get started!"

"promise!"

Li Ke came to power, which attracted the attention of many people both on and off the stage. First of all, he was the son of the emperor and the current King of Wu.

Secondly, during my time in the academy, I won everyone’s recognition for both my knowledge and my conduct as a person!

Compared with the arrogance of Wei King Li Tai, Wu King Li Ke seemed much more approachable, and many students were willing to associate with him.

Li Ke also helped whenever he could. As long as he didn't go out of his way, he would help. This move won praise from many students.

Because of this, his relationship with Li Tai became worse and worse.

"How are my three children doing in the academy?"

Li Shimin stopped calling me, so he addressed Li Gang as me.

Li Gang had a complicated look on his face and replied with some pity: "The King of Wu has a resolute character and is polite and virtuous. Although his academic performance is not as good as that of the King of Wei, he is highly praised by students!"

Fang Xuanling stood aside and hesitated, but finally sighed and said nothing more.

Wei Zheng wanted to step forward, but was pulled back by Du Ruhui, who was standing beside him. He shook his head and whispered, "Your Majesty has made his own decision. We'd better not interfere."

Wei Zheng was startled, then sighed and returned to his seat.

Li Shimin looked at the three sons who were high-spirited on the stage and felt very complicated.

Among the several sons, Li Ke's character and appearance are most similar to his own, but his identity is destined to be irrelevant to that identity.

Now the prince is doing very well, he keeps his duty, loves his brothers and sisters, and has made great progress in his studies. The courtiers have repeatedly praised the prince's virtue.

"I hope Master Li can teach me more. I thank you!" After saying that, he cupped his fists at Li Gang.

Li Gang was speechless, looked at Li Shimin carefully, and then laughed.

"Your Majesty, don't worry. After all, he is still a student of the academy. No matter what happens in the future, he is at least a good young man and a good student at this time."

Everyone was talking about it in confusion, and Yuchi, who was listening to it, didn't think about it at all.

Li Ke's discussion is not much different from Zheng Ming's discussion, but he has his own new insights and even introduces new ideas.

"Everyone, please see!"

What Li Ke brought was a large basin with a smaller one on top, and a slightly smaller one on top. At this time, by adding saltpeter, the bottom two basins had frozen.

But the difference is that the top one is not frozen. Although the temperature drops and even some hands are frozen, there is no ice.

"Huh? It's interesting!"

Ji Song looked surprised. He didn't expect Li Ke to think of this, but he didn't say anything.Today they are the protagonists. Through their own exploration and efforts, they show the charm of Gewu to the world. No matter what they do in the future, they will be the pioneers of Gewu theory. He should not rob them of the honor that belongs to them!
Li Shimin was also a little surprised and looked at Li Gang, wanting him to explain to him.

But what disappointed him was that Li Gang also smiled bitterly and said: "I am devoted to literature and classics, and I don't understand these."

Then he looked at Ji Song who was smiling and said with a smile: "It seems that boy should understand. Your Majesty just needs to be treated less."

Li Ke did not keep everyone waiting and continued: "Everyone has also seen that, first, the water in the second basin has also frozen, but the top one has not. Why is this?"

It was also a rhetorical question, but he answered directly: "So I have a bold guess based on this phenomenon. Please wait a little!"

Everyone didn't know what kind of medicine he was selling in his gourd, but in order to find out, they didn't say anything.

As time passed, the sun gradually became fiercer.

The better thing is that the college students can still bear it no matter whether they just study hard or pay attention to physical exercise.

But he didn't dare to let it go. Ji Song said something to the steward behind him, and the steward left immediately.

After a while, the steward led many people carrying wooden buckets to the audience, and poured out the sour plum soup that was still chilling, allowing the students to take it.

Of course, everyone on the stage will not forget Ji Song. At this time, a waiter has already served it to everyone.

Li Shimin drank it all in one gulp and exhaled, feeling that his whole body was suddenly clear.

"Look, everyone, why is this happening?"

At this moment, someone noticed something unusual on the stage.

Everyone hurriedly looked around and saw that there was no difference in the top one, but the water in the second basin had gradually melted. Although the bottom one also melted, it was much slower than the one in the middle.

Li Ke breathed a sigh of relief and said loudly: "Everyone has also seen that in the same environment, ice melts at different speeds. This is puzzling. What is the reason?"

"So, I boldly guessed, is this related to other things, or is there something we don't know about?"

He seemed to be completely immersed in his own world at this time, unfolding his discussion one by one, which surprised everyone!

Ji Song nodded and smiled. He was so surprised. He didn't expect Li Ke to give him such a big surprise!
Li Ke finally regretted: "Although I discovered this change, I can't figure out the reason."

He bowed to Ji Song and said, "Sir, please clear up my doubts!"

Ji Song nodded and smiled: "Old rules, I will explain them to you after the game is over, you go down!"

Li Ke was helpless, but the rules were indeed like this, and so was Zheng Ming who was the first to show off!
"Next!"

The next few people all have similar opinions. Although they also have new opinions, they don’t understand what they mean or why!

Among them, only a young man named Li Yifu was pretty good. He unexpectedly got a lot of pure saltpeter from somewhere, which greatly reduced the amount of saltpeter used to freeze water.

From this, he came to the conclusion that after purified nitrate, both the freezing efficiency and the amount used will be greatly reduced.

This surprised Ji Song.

"You are very good. You can think of this level, which shows that you have put your heart into it, but have you ever thought about using the purification method in other places?"

Seeing the young man thoughtfully, Ji Song didn't say anything else, but asked him to go down and wait!
