Throughout the day, Li Zhi taught these selected young people to learn the basics of chemistry in the Foundry Bureau, among which Li Zhi was very optimistic about a young man named Xu Zhou, who was like crazy when he learned, and other students only knew a little about the basics of chemistry in a day, but Xu Zhou was not completely proficient, but in terms of understanding, he was far higher than other young people.

It can be said that Li Zhi understands everything about it, and his thinking is very quick.

"That's it! That's all for today, you all go back first, and continue tomorrow! After speaking, Li Zhi turned around and left.

There was a lot of talk in the classroom.

"I think Your Highness's is so interesting."

"yes, yes, it turns out that there are so many ingredients in these gases we breathe... Oxygen is the most important. A young man exclaimed.

"Your Highness just said that in fact, steelmaking is a process of chemical reactions, and chemical reactions are happening everywhere in our lives."

"It's amazing!"

"I must study hard, there are so many amazing things in this world..."

Li Zhi did not know what these young people were talking about, but he knew that after this day's lesson, the seeds of science would inevitably be planted in the psychology of these students, and as for the result, it would depend on their own development and understanding.

After returning to the palace, Li Zhi began to hide in the study, burying his head in hard work, knowing that he would give up late at night.

I saw a few booklets with the cover written on the table, the content of which was not much, but the basic framework was still there, and the cover read, chemistry, physics!

That's right, this is the textbook that Li Zhi transcribed through the crystallization of civilization, which is different from the basic chemistry and physics knowledge of junior high school in later generations, and the content of these two books edited by Li Zhi is only part of the basic content, and most of them are mainly biased towards industrialization, but there are a lot of annotations, and they are also specially annotated by Li Zhi in order to take care of these young people's foundation may not be solid.

However, the contents of this book need to be written by Li Zhi for a little more time, and then it needs to be transferred to a specially set up printing workshop within the Casting Bureau to be printed in movable type, so as to distribute it, so as to ensure that each of these students has a copy.

Li Zhi got up from the chair, stretched lazily, sat down for a day, his body was a little stiff, he moved his body simply, looking at the darkness outside the window, Li Zhi also found that he was also a little sleepy.

Just when Li Zhi wanted to sleep in wide clothes, suddenly, the window creaked, and a person jumped in from the night.

"Your Highness!"

"Huh?" Li Zhiyi turned his head and found that Li Tong was already standing in front of him.

Seeing this, Li Zhi deliberately looked at whether the window was closed, and he was scared last time.

"What's the matter at this late hour?" Li Zhi was slightly displeased, but he didn't mean to blame.

Li Tong scratched his head and said, "Your Highness, the person you asked me to find has been found!" ”

What Li Tong said was Ma Shuangquan, who was related to the smuggling case at the border gate that Li Zhi asked him to find a few days ago, so Li Zhi suddenly came to his senses, walked to the table, and then sat down and said, "How is the situation?" ”

"Back to His Highness, when we found Ma Shuangquan, he was about to die, so we sent him to a medical hall not far from the palace to recuperate!"

Li Zhi was a little puzzled, not that he wanted this Ma Shuangquan to die soon, but that he was wondering why the murderer didn't kill him directly, so he hurriedly asked, "Where did you find him?" ”

"In the cellar of a restaurant in the east of the city."

"In the cellar?" Li Zhi was very surprised, this is so hidden that it can be found? It seemed that it was the right choice to let Li Tong be in charge of forming Jinyiwei, so he asked curiously, "How did you know that you were in the cellar of this restaurant?" ”

Li Tong scratched his head and said, "I found out through a friend on the road." ”

"I didn't expect you to have such a way? Not bad, not bad! Li Zhi was a little surprised, this Li Tong has a lot of means.

"Has the murderer been caught?" Li Zhi asked, he thought that since the horse was found, the murderer must have been caught, but the result was unexpected.

Li Tong said ashamedly, "Please condemn Your Highness!" The murderer had already been taken down by me, but I didn't know that he suddenly took advantage of my unpreparedness, jumped into the secret passage hidden in the cellar wall, and then disappeared. But he was also injured by me, presumably he couldn't run far, and I ask Your Highness to let the lowly general atone for his sins, and the lowly position will definitely catch him for His Highness! ”

Although Li Zhi didn't like it in his heart, he also knew that this matter was not good for Li Tong, but that the murderer was too cunning, but he didn't expect to dig a secret passage in the cellar, which is careful enough, Li Zhi secretly slandered, this person is afraid that he is a rat...

"It's okay, I can't blame you for this, but you must not take it lightly, and you must catch the thief to this king!" Li Zhi comforted.

Then he said, "Also, be sure to protect this horse Shuangquan, this king suspects that the thief may come to the door and do something to Ma Shuangquan." Speaking of this, Li Zhi suddenly thought of something, so he said: "Order, you let the soldiers of Jinyi Guard secretly investigate all the medical halls in the city, and do not startle the snake, since the thief was injured by you, presumably he will also find a place to heal." ”

"Yes!" Li Tong nodded, agreeing with this.

"Alright, you go down first..."

Then, when Li Tong was about to leave, Li Zhi said lightly behind him: "Remember to close the window!" ”

Li Tong stumbled when he heard this, and secretly slandered himself, this highness is too stingy, he can really hold grudges.

With a creak, Li Tong disappeared into the night.

Li Zhi looked at the closed glass window, and then breathed a sigh of relief.

By the way, the glass window has not been put into the market now, but Li Zhi has installed it all over the Xinwang Mansion in order to look good and highlight a little modernity, because he feels that the glass window is not suitable for the market, because now the glass bottle is a high-end route, once the glass window is available, it will undoubtedly lower the force of the glass bottle from the side.

And the practicality is not high, it is impossible to sell a glass window at a sky-high price, but the rich man bought it back and was stolen within two days, is this necessary? It's impossible to ask the family to take care of it for the sake of a window, right? So it's far from necessary.

After the glass bottle enters the market for a period of time, the price tends to be flat, and it can enter ordinary people's homes and become a daily necessities that ordinary people can afford, Li Zhi will make the glass window come out, because the quality of the paper paste window in this era is really poor, although it is not as good as the TV series that can be pierced with a finger dipped in saliva, but it is not much better, and it is not soundproof, which is really a lot of criticism.

It's not too early, after Li Tong left, Li Zhi just thought for a while and fell asleep hastily, I'm so tired today....
