Chapter 364 New Stuff

"Your Highness, this cannon has just been made. I will try to cut it with a hydraulic boring machine. Read М"

There is another fixed cannon in the workshop.

This cannon is also fixed on a wooden frame.

The center line of the muzzle is consistent with the center line of the boring tool.

As long as the wooden frame is pushed to the boring machine, the cutting can begin.

Zhao Xu nodded, and then he looked at the boring machine.

There is a bucket of yellow oil there, which is lard.

When the drilling machine drills the barrel, the drill bit needs lard lubrication, otherwise the drill bit will be more easily damaged. After all, the problem of wear and tear cannot be avoided.

The same is true for boring machines, and even the lathes to be used in the future need this lubricant.

"Well, if the effect is good, this king will call back the cannon in the army to cut it again, and then you can test the power and range of the cut cannon." Zhao Xu patted the cannon, this is another task.

"Yes, Your Highness." The king replied.

After giving instructions, Zhao Xu went straight to the Science and Technology School.

He was not too excited.

Because the hydraulic drilling machine had already accumulated technology for him.

Now it was just a matter of time.

It was for this reason that Wang Ying dared to promise him that it would be completed within three days.

Although he was dull, he was not stupid.

He never made random promises about things he was not sure of.

Arrived at the school.

Wang Chong was checking the students' homework during this period.

He asked them to write down chemical formulas and physical formulas on the blackboard one by one.

Seeing Zhao Xu coming, he immediately asked the students to return to their seats.

"Your Highness." Everyone shouted together.

Zhao Xu felt a sense of accomplishment as he scanned the students one by one.

A few months ago, they were still a group of ignorant people.

Now, they can flexibly master various formulas and scientific concepts.

There is no need to explain everything to them when communicating with them.

Generally speaking, they have initially acquired the abilities of contemporary junior high school students.

After all, during this period, they studied hard except for eating, and only studied chemistry, mathematics, and physics.

Many students even studied until midnight.

At this stage, Zhao Xu felt it necessary to give these students a chance to make something of themselves.

Then slowly let them build the chemical industry foundation and physical machinery foundation of the four counties from scratch.

As for mathematics, it naturally has its important role. After all, the higher the technology goes, the more calculation is needed.

This belongs to basic science. Although the benefits cannot be seen in a short time, it is necessary to spend money to cultivate such talents.

"This king said that he would give you a task. Now this task is here. This king has told you about the saponification reaction. Now you are a group of ten people. Within one day, this king wants to see the finished soap."

After a pause, he continued: "Now, you divide into groups first. Each group gives the required materials to this king, and this king will provide them to you. Each group cannot communicate with each other, and each group relies on its own ability."

For him, this is also an assessment practice for the students.

Let them be able to complete the manufacture of the same chemical alone.

Expanding it further, this is a chemical production line.

"Yes, Your Highness." Zhao Xu's order did not make the students retreat, but instead they were eager to try.

These few months of study washed away their old understanding of the world.

After all, the King of Yan personally demonstrated one experiment after another, breaking many things that they thought were magic.

Faced with the rich content in the textbooks, the door to a new world slowly opened in front of them.

They were happy to use their own hands to turn the textbooks into real objects.

After saying yes, the students started to move.

Soon, the 322 students were divided into 32 groups.

There were eleven people in two groups.

Wang Chong was the first to hand the required materials to Zhao Xu.

He smiled and returned to his seat.

Since the establishment of the Science and Technology School, Wang Chong had basically nothing to do with the research and development of the Arms Department.

He just focused on the school, responsible for his own study, and urged the students to study.

Wang Ying did not allow him to do anything else.

In his opinion, letting his son study in the school was much more important than assigning him some work.

Wang Chong was a little reluctant at first, but after being exposed to the vast amount of knowledge in the textbooks, he was immediately deeply immersed in it and could not extricate himself.

The little arrogance he had at the beginning also disappeared completely.

He knew very well that if he did not study hard, it would not take long for him to be replaced by the students in the school.

After Wang Chong handed it in, the second student with squinted eyes and a clean face handed in the list.

Zhao Xu smiled gently.

The name of this student was Qu Sheng.

Among the students, he and Wang Chong were the best.

In the last official examination, he got full marks in mathematics.

And later facts seemed to prove that he was a natural science student.

He was also good at physics and chemistry.

After collecting all the material lists, Zhao Xu looked at them one by one.

Among the thirty-two lists, only one list was missing a certain material.

But they were generally correct.

As expected, the unqualified lists were from the children of craftsmen.

Because they were illiterate, the children of craftsmen had a poor foundation and had to learn to read before they could read the textbooks.

So they learned very slowly.

But Zhao Xu did not intend to give up on them.

These children of craftsmen also worked very hard.

Giving them hope was equivalent to giving hope to all the craftsmen.

Call the students who made mistakes to criticize and correct them.

Zhao Xu first asked the students to build a stove in the yard.

Then he asked Wang Ying to send people to get meat oil, quicklime, soda ash, salt, and sent people to the glass workshop to get a 30-centimeter glass jar.

In the afternoon, all these things were ready.

Zhao Xu did not participate, but just moved a chair to sit on the side and watched them toss.

Watch how they synthesize materials from scratch and make soap.

"Pour quicklime into the sink, dissolve it and then add soda ash." Five meters away from Zhao Xu, Wang Chong assigned tasks to the students in the group in an orderly manner.

Professional terms kept popping up in his mouth, all of which were from the textbooks.

The students were familiar with it and understood why Wang Chong asked them to do this.

After a while, billowing white smoke rose from the whole venue.

This was the steam produced by the quicklime dissolved in water and heated up.

When a clear solution appeared in the sink, several students added soda ash, and then waited.

Half an hour later, a layer of ice-like film appeared on the water surface of the sink, and another student collected it.

At the same time, some students had already heated the meat oil.

At this time, the students poured the collected white film into the hot oil and stirred it continuously.

Then, they added salt.

Soon, white solid appeared in the glass jar.

The students lifted the glass jar, covered the mouth of a pottery jar with cloth, and poured the contents down. The solid remained on the cloth, and the liquid flowed into the pottery jar.

Finally, the solid on the cloth was pressed into shape and dried.

In the evening, each group handed him a soap.
