Chapter 365: Yanshan Movement

"Very good. Read"

Looking at the neat and beautiful soap in front of him, Zhao Xu smiled with satisfaction.

This time he really watched the whole process, but the students gave him a perfect answer.

A sense of self-satisfaction as a teacher rose in his heart.

Wang Chong, Qu Sheng and other students exchanged glances with each other.

They were very nervous throughout the process, fearing that they would fail.

Now that they succeeded and got the approval of King Yan, a sense of joy arose from their hearts.

The most important thing is that this time they made soap from scratch by themselves.

This is a verification of the knowledge in the textbook.

What King Yan told them is true, without any falsehood.

"It's really magical. All this can't be seen or touched, but it just happened." Qu Sheng and Wang Chong stood side by side, still savoring it.

The quicklime dissolved in water and turned into calcium hydroxide.

Calcium hydroxide and soda ash turned into sodium hydroxide, which is the caustic soda needed for the creation reaction.

The final saponification reaction produced soap and by-product glycerin.

And this glycerin, judging from the knowledge he has mastered, will play a very important role in the future.

"This is just a small thing. You will continue to see more amazing things in the future." Zhao Xu said with a smile.

Wang Chong looked excited, "After learning these things taught by Your Highness, I will die without regrets."

"Hahaha..." Zhao Xu laughed.

He wanted the students to have this attitude. It is enough to hear the truth in the morning and die in the evening.

He also exchanged the experience of making soap with the students.

Zhao Xu said to Wang Chong: "This saponification reaction is just the beginning. I want you to go to the North Square District of Chengdefang to set up a soap workshop in person, and provide a steady supply of soap to the business in the future."

After thinking about it, he said to Qu Sheng: "How about Qu Sheng taking the lead in this experience?"

The other students did not speak, so they naturally could not make any suggestions.

After all, Qu Sheng was recognized as the best learner among them.

They would also ask Qu Sheng if they did not understand something.

Wang Chong heard this and made a bitter face, "Your Highness, has your subordinate fallen out of favor?"

"Well, you guessed it right." Zhao Xu laughed.

"No, Your Highness." Wang Chong pretended to be pitiful.

Zhao Xu was too lazy to pay attention to him. Compared with Qu Sheng's dullness, Wang Chong was obviously much more lively and often acted funny in front of him.

Turning to Qu Sheng, Zhao Xu said: "Do you have this confidence?"

"Yes." Qu Sheng's tone was very firm.

He knew that the King of Yan gave him this opportunity because he valued him.

But at present, the King of Yan just thought that he was a good student, and letting him set up a soap shop was to verify his practical ability.

Only if this matter is done well, he can be reused like Wang Chong.

"Okay, I will tell the head of the king, and ask him for anything you need." Zhao Xu said.

Then he looked at the students and saw that they all had envy in their eyes, and said: "I know what you are thinking, don't worry, as long as you learn the textbooks well, I will let you be independent in the future."

The students were excited when they heard this, and there seemed to be light in their eyes.

After explaining the matter, Zhao Xu returned to the palace.

After dinner, he went to the study.

After half an hour of hard work, he folded several drawings.

This is the mineral map of Yanzhou, and how to distinguish various minerals.

After so much trouble, this thing is finally completed.

Now he intends to let the students of the Science and Technology School gradually establish various industries in the four counties.

Another obstacle to industrial development is minerals.

In ancient times, only a small part of the various elements in the periodic table were used, mainly gold, silver, copper and gold.

But other elements are equally important, and even related to the rise of industry.

Now, it is necessary to find all these minerals.

In this way, there is no need to panic when they are needed.

Thinking of handing these maps to the Political Affairs School the next day and organizing students to study, he started to compile teaching materials again.

In his opinion, this group of students will basically be able to master the junior high school level knowledge by the end of the year.

Next, they will learn more advanced things.

This involves high school level knowledge.

In addition, the Political Affairs School and the Military School have corresponding improvements.

Taking advantage of the free time in the evening, he naturally has to busy with this matter.

After all, you never know when the war will start again.

The next day.

He first went to the Science and Technology School and gave some lectures. Qu Sheng went to Chengdefang and personally established a soap shop.

Then he went to the Government Affairs School.

After the lecture, he gathered the students of the Mineral Exploration Department selected by Liu Fu and showed them the mineral map and the characteristics of various minerals.

In the next few days, he paid attention to Qu Sheng's soap shop while giving lectures to the students of the Mineral Exploration Department.

That day, Zhao Xu went to the Government Affairs Department as usual.

Suddenly Chang Wei found him.

"What's wrong?" Zhao Xu asked.

"I received news from Wu'an County that more than a thousand infantrymen of the Black Iron King's Tent tried to cross Yanshan and enter Yan County, but were blocked by our fort. They attacked the fort, but were beaten back by our artillery." Chang Wei said.

"More than a thousand people? Beidi is sending out more and more troops. It seems that our plan to remove my bastion and enter Yan County as we did before is just a daydream." Zhao Xu narrowed his eyes.

Looking to the north, he continued: "Now the Beidi people are lucky enough to find someone who can make artillery for them. Next, they may attack the bastion with artillery."

Chang Wei nodded, with worry in his eyes, "If the Beidi army attacks the bastion with artillery, it will undoubtedly be very bad news. This will offset the advantages of our royal army."

"That's not necessarily true. As the saying goes, the devil is one foot high, and the way is ten feet high. This king will make their artillery useless." Zhao Xu suddenly laughed.

Confidence is very important for soldiers.

He didn't want the news that Beidi had artillery to spread, which would arouse the fear of Beidi in the hearts of the royal soldiers.

On the battlefield, the belief of winning is very important.

Chang Wei realized that there was something behind the words of the King of Yan, and he hurriedly asked: "Does your highness have a solution?"

Zhao Xu decided not to keep it a secret, so he said: "This king is asking Wang Ying to improve the current artillery, which will be improved in power and range."

In fact, Zhao Xu is very confident in his own artillery.

First of all, his artillery is made of steel.

In modern times, steel cannons did not appear until the mid-19th century.

The second is bore reduction, which basically makes his cannon at the level of the top cannons in the mid-19th century, that is, during the Opium War.

And this missionary was able to get to the far north, so he must not be a high-level scholar in this Russian country, and basically does not master the most advanced cannon-making methods in the country.

Maybe he understands the principles of cannon-making, but whether he can reach his level of cannon is worth discussing.
