The next day, Li Zhi got up early in the morning, and then hid in the study to continue compiling textbooks, when suddenly Zhou Man walked in and said respectfully: "Your Highness!" ”

"What?" Li Zhi just glanced up at Zhou Man slightly, and then continued to write with a pen.

"Your Highness, there is news from Beijing, yesterday Yu Zhengzhi, the secretary of the Criminal Department, impeached Your Highness as soon as possible..."

Hearing this, Li Zhi gently put down the pen in his hand, then raised his head and looked at Zhou Mandao: "Heh, what is the impeachment of this king?" But it doesn't hurt to say it! ”

"It is against the ancestral system to say that His Royal Highness has insulted the royal face, mixed up with these cheap businessmen, and not only that, but also engaged in cheap business!" Zhou Man then said.

After hearing this, Li Zhi didn't get angry but laughed and thought to himself, "Yu Zhengzhi, the secretary of the Criminal Department, knows that it is his second brother Li Jie's famous dog legs, guns, where to shoot, and to make such moths, it is estimated that he guessed that those merchants were killed by this king, but this Li Zhi will not say it", and then said with a smile: "Is it against the ancestral system?" How dare he say... Let's ask which prince of the Great Xia Dynasty is not in business now? I just used this matter to disgust the king. Then he added, "Then how did this matter end?" ”

Zhou Manlian said, "At that time, only Yu Zhengzhi and the Second Princes' Party stood up to impeach His Royal Highness, and the princelings and the Bachelor's Party all had an attitude of watching the fire from across the strait, and in the end, His Majesty came forward to veto Yu Zhengzhi with a tough attitude, so he gave up!" ”

"Heh, it seems that this cheap daddy still values me." Li Zhi muttered, then thought about it and waved his hand and smiled: "Okay, Zhou Man, you should step back first, this king knows." ”

"Yes!"

After Zhou Man left, Li Zhi grinned, and then put the matter behind him as a joke and began to continue to do what he was doing.

As for whether he left this matter behind, it is unknown, but with Li Zhi's habit of retribution, he will inevitably give Li Jie a counterattack.

........

Haihang City, in the palace of the king of Qi.

"Bastard! This king ordered that he couldn't do any little things, what use did he want, come on, and order the black guard to give Yu Zhengzhi to this king! Li Jie sat in the main hall and said frantically.

But as soon as Li Jie's voice fell, a man wearing a crane and holding a feather fan not far away said, "Your Highness, no!" Yu Zhengzhi is still very useful, and he can't be easily removed! ”

Although Li Jie said that he was unreasonable on weekdays, he still admired this handsome man, so he waved his hand after a little hesitation and said: "Forget it, leave him alive!" Then he said respectfully to the man: "I don't know what Mr. said about Yu Zhengzhi, what is the use?" ”

The man shook his feather fan, and then said with a smile: "Your Highness can't be killed, but you can believe in the king!" ”

Li Jie reacted instantly, and said with a smile: "Borrow a knife to kill!" ”

The two looked at each other and laughed.

Li Jie showed ruthlessness and said in a low voice: "Kill the first-class member of the Shangshu Imperial Court of the Criminal Department, Li Zhi I see how you live?" The more he thought about it, the more excited Li Jie became, and shouted: "Come on, prepare for a banquet, this king wants to have a good drink with his husband..."

After a while, the Qi Wangfu set off a burst of singing and dancing, and the sound of warblers and swallows.

......

And Li Zhi here.

Finally, it was not until the evening that the textbook was compiled, and then he called Zhou Man and asked him to send the textbook to the printing workshop of the Foundry Bureau to be printed, and then he rested contentedly.

After a few days, Li Zhi went to the Foundry Bureau early in the morning to teach chemistry knowledge, and slowly, these selected young people gradually had different views on the subject of chemistry, and even had their own unique set of experimental methods according to the propositions put forward by Li Zhi.

On this day, in the classroom, after class, after the students were all gone, Xu Zhou sneaked to the laboratory next door.

The whole laboratory is almost arranged according to the layout of a modern laboratory, because there are fewer students, only a dozen people, so it is arranged according to the arrangement of two people, seven or eight experimental tables are arranged, and there is a lectern belonging to Li Zhi, and there are all kinds of experimental equipment on the table.

After looking around, Xu Zhou sneaked into the laboratory, then took out the book, and simply did an experiment according to the tutorial in the book, looking at the chemical reaction produced in a set of glass experimental equipment in front of him, the smoke in the container, showing a surprised and proud look, and then holding the newly printed chemistry textbook in the printing workshop of the Foundry Bureau and looking at it with relish.

Then I looked at the tutorial according to Yibi, and began to try to do experiments curiously, but there were failures but successes along the way, fortunately, the experiments done by Xu Zhou were all relatively simple gas preparation experiments, and the production was nothing more than some gases such as hydrogen and oxygen, otherwise her life would not be guaranteed.

It wasn't until the evening that Xu Zhou reluctantly disposed of all the test residues according to the instructions in the book, and then left the classroom.

Of course, Li Zhi didn't know what this student who loved to learn did after school that day.

The next day, Li Zhi came to the classroom with a few pieces of ore, and then asked the students to come to the laboratory next door, where he wanted to do an experiment.

Entering the laboratory, looking at the young people in the audience and the neat experimental equipment in the laboratory, Li Zhi suddenly felt like a world away, like returning to his student days.

But this feeling was fleeting, broken by the honorifics of the students: "Hello Your Highness! ”

Adjusting the state, Li Zhi coughed lightly and said: "Today, this king will teach you how to prepare the sulfuric acid in the "three acids and two alkalis". ”

The students listened to it and were excited, finally, His Royal Highness was going to teach them this, in the past, Li Zhi taught them some simple experiments, which were all completed very simply, and they were not fun.

These "three acids and two alkalis" were mentioned as early as when Li Zhi taught them the basics of chemistry, which are nitric acid, sulfuric acid, hydrochloric acid, sodium hydroxide, and sodium carbonate.

Among them, sodium carbonate is not alkali, but salt, commonly known as soda ash and soda, which is alkaline.

Nitric acid is generally used in the manufacture of fertilizers, explosives and nitrates, and has a wide range of industrial uses.

The use of sulfuric acid is much more extensive than nitric acid, and can react with many metals, not only to make fertilizers, explosives, some drugs and pigments, batteries have their existence, oil purification, or Li Zhi to obtain a higher degree of alloy are inseparable from sulfuric acid.

As for hydrochloric acid, sodium hydroxide and sodium carbonate, they are not all outlined here.

Suffice it to say, three acids and two bases are the basis of industry, and it is no wonder that these students are so excited.

"Alright, now this king will teach you how to make this sulfuric acid."

The students' eyes widened and their ears pricked up, for fear of missing a word.

Li Zhi raised the piece of ore he had been holding in his hand, and then said, "Do you know what this stone is?" ”

PS: Sorry, this chapter is a little late, because I was in the car last night, sat in the car all night, and then went home and slept early and didn't get up until the afternoon .... A late one.... I'm sorry!
