Become a feudal king from today

“Very good. Read”

Looking at the neat and beautiful soap in front of him, Zhao Xu showed a satisfied smile.

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

A kind of teacher's complacency gradually rose in his heart.

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

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

Now that they succeeded and were recognized by King Yan, a kind of joy welled up in their hearts.

The most important thing is that this time I made soap from scratch by myself.

This is a verification of the knowledge in the textbook.

Everything King Yan told them was true, without any falsehood.

"It's really magical. It's all invisible and intangible, but it just happened." Qu Sheng and Wang Chong stood side by side, still thinking about it now.

Quicklime dissolves in water and becomes 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 yields soap and glycerin as a by-product.

Judging from the knowledge he has mastered, this glycerol will also 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 smiled.

Wang Chong looked excited, "After learning these things taught by His Highness, I will die with no regrets."

"Hahaha..." Zhao Xu laughed.

He just wants the students to have this attitude. It is enough to hear the Tao in the morning and die in the evening.

I also shared my 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 Beifang District of Chengde Fang to establish a soap shop in person, and provide a continuous supply of soap to the business in the future."

After thinking for a while, he said to Qu Sheng, "How about Qu Sheng taking the lead in this insight?"

The other students didn't speak, so naturally they couldn't comment.

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

They would ask Qu Sheng if they didn't understand something.

When Wang Chong heard this, he grimaced and said, "Your Highness, have you fallen out of favor?"

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

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

Zhao Xu was too lazy to pay attention to him. Compared to Qu Sheng, who was dull, Wang Chong was obviously much more lively and often played tricks in front of him.

Turning around, Zhao Xu said, "Do you have the confidence?"

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

He knew in his heart that King Yan valued him by giving him this opportunity.

But at present, King Yan just thinks that he has learned well, and asking him to establish a soap workshop is to verify his practical ability.

If this is done well, he can be reused like Wang Chong.

"Okay, I will tell Mr. Wang and ask him for anything you need." Zhao Xu said.

Then he looked at the students and saw envy in their eyes, and said: "I know what you are thinking, don't worry, as long as you learn the teaching materials well, I will let you be your own master in the future. "

When the students heard this, they suddenly became excited, and there seemed to be a light in their eyes.

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

After dinner, he went to the study.

After working for half an hour, he folded several drawings.

This is a mineral map of Yanzhou and how to identify various minerals.

After working on it for so long, this thing is finally finished.

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.

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

But other elements were equally important, even relevant to the rise of industry.

Now, it is necessary to find all these minerals.

In this way, there is no need to panic when you need to use it.

Thinking of handing these pictures to the Government Affairs School the next day and organizing students to study, he started compiling teaching materials.

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

Now let’s learn more advanced things.

This involves high school level knowledge.

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

Taking advantage of his free time at night, he naturally had to work on this matter.

After all, there is no telling which day war will start again.

The next day.

He first went to the Science and Technology School and gave some lectures. Then Qu Sheng went to Chengdefang and built the soap factory himself.

Then he went to the Government Affairs School.

After giving lectures, he summoned the students from the Prospecting Department selected by Liu Fu and showed them mineral maps and the characteristics of various minerals.

In the next few days, while paying attention to Qu Sheng's soap shop, he also gave lectures to the students of the Prospecting Department.

On this day, Zhao Xu went to the Political Affairs Department as usual.

Suddenly Chang Wei found him.

"What's wrong?" Zhao Xu asked

"The general received news from Wu'an County. More than a thousand infantrymen from the Black Iron King's tent tried to cross Yanshan Mountain and enter Yan County, but were blocked by our Wubao. They launched an attack on Wubao, but were hit by our artillery. Go back." Chang Wei said.

"More than a thousand people? More and more soldiers and horses are dispatched from Beidi. It seems that we want to pull out the king's fortress and enter Yan County as we did before. But they are just daydreaming." Zhao Xu's eyes narrowed. stand up.

Looking to the north, he continued: "Now that the Beidi people have gotten lucky, they have found someone who can build 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 advantage of our royal army."

"That's not necessarily true. As the saying goes, if the devil is as high as the Dao, I will make their artillery useless." Zhao Xu suddenly laughed.

Confidence is very important to soldiers.

He didn't want the news about the artillery in Beidi to spread out and arouse the fear of Beidi in the hearts of the soldiers in the palace.

On the battlefield, the belief in victory is very important.

Chang Wei realized that there was something wrong with King Yan's words, and he hurriedly asked: "Does Your Highness have any idea?"

Zhao Xu decided not to sell out, so he said: "I am asking Wang Ying to improve the current artillery, and the power and range will be improved."

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

First of all, the material of his cannon is steel.

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

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

And if this missionary can get to the far north, he must not be a senior scholar in this country of Russia, and he will basically not master the most advanced artillery-making methods in the country.

Maybe he understands the principles of building artillery, but whether he can reach the level of his artillery is questionable.
