"Your Highness, this cannon is just made. Please try cutting it with a hydraulic boring machine right away."

There is also a fixed cannon in the workshop.

The cannon is also fixed on a wooden stand.

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

Just push the wooden frame toward the boring machine and the cutting will begin.

Zhao Xu nodded, then he looked to the boring machine.

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

When drilling the barrel of the drilling machine, the drill bit needs to be lubricated with lard, otherwise the drill bit will be more likely to be damaged. After all, the problem of wear cannot be avoided.

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

"Well, if the effect is good, I will transfer the cannons in the army to cut them. Then you can test the power and range of the cannons." Zhao Xu patted the cannons, which was another mission.

"Yes, Your Highness." Wang Ying said.

After giving this instructed, Zhao Xu went straight to the Science and Technology Academy.

He was not overly excited.

Because the hydraulic drilling machine has accumulated technical accumulation for it.

It's just a natural outcome now.

It is precisely for this reason that Wang Ying dared to assure him that he would complete it within three days.

Although he is dull, he is not stupid.

He never promised something unsure of.

Arrive at school.

Wang Chong is checking the students' studies during this period.

Let them write chemical formulas and physical formulas one by one on the blackboard.

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

"See Your Highness." Everyone shouted together.

Zhao Xu felt a sense of accomplishment as his eyes swept over the students one by one.

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

Now, they are able to flexibly master various formulas and scientific concepts.

When communicating with them, you don’t have to explain everything to them.

Overall, they have initially possessed 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 light up the lights and read until midnight.

At this stage, Zhao Xu felt it was necessary to give these students the opportunity to make some things on their own.

Then they will slowly build the chemical industry foundation and physical machinery foundation from zero to four counties.

As for mathematics, it naturally has an important role. After all, the more technology goes, the more computing it needs.

This is a basic science, but there is no benefit in a short period of time, but you must spend money to cultivate such talents.

"I said that I would give you a task. Now that this task is coming, I have told you about saponification reactions. Now you have ten people in a group. Within one day, I will see the finished soap."

After pausing, he continued, "Now, you can group first. Each group will give me the materials you need. I will provide you with them. Each group cannot communicate with each other, and they all rely on their own abilities."

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

Allow them to make a chemical alone.

If you expand it, this is a chemical production line.

"Yes, Your Highness." Zhao Xu's order did not let the students fade away, but instead he was ready to go.

These months of study have washed away the old understanding of the world in their minds.

After all, the King of Yan personally demonstrated experiments and cracked many things they believed to be magic spells of gods.

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

They are happy to use their hands to turn the textbook into real objects.

After answering, the students started to move.

Soon, 322 students were divided into 32 groups.

There are eleven people in two groups.

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

He smiled and he returned to his seat.

Since the establishment of the Science and Technology Academy, Wang Chong has basically lost the opportunity to research and construction matters in the Military Affairs Department.

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

Wang Ying also did not allow him to do anything else.

In his opinion, letting his son listen to his studies in school is much more important than giving him some work.

Wang Chong was a little unhappy at first, but after getting into the vast amount of knowledge in the textbooks, he was immediately trapped in it and could not extricate himself.

The arrogance I had at the beginning also disappeared completely.

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

Wang Chong had handed over the letter, and the second student was squinting his eyes, and the white student handed over the order.

Zhao Xu chuckled softly.

The student's name is Qu Sheng.

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

In the last official exam, his math skills were full marks.

Later, facts seemed to prove that he was a natural science student.

Physics and chemistry are equally excellent.

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

Among the thirty-two orders, only one item of material is missing on the order.

But it's basically right.

This unqualified order is unexpectedly owned by the children of craftsmen.

Because they are illiterate, the children of craftsmen have poor foundations and must first recognize words before they can read the textbooks.

So they learn very slowly.

However, Zhao Xu did not plan to give up on them because of this.

These craftsmen also worked very hard.

He gives them hope, which is equivalent to giving all craftsmen hope.

Call a group of students who did something wrong and criticize and correct it.

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

Then he ordered Wang Ying to send someone to get meat oil, quicklime, soda ash, salt, and then to the glass shop to get a 30-centimeter-diameter glass jar.

In the afternoon, all these things were ready.

Zhao Xu didn't participate, just moved a chair and sat next to them, staring at them and tossing.

See how they synthesize materials from scratch and make soap.

"Populate 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 vocabulary is constantly popping up from my mouth, all of which are out of the textbooks.

The students were familiar with each other and understood why Wang Chong asked them to do so.

After a while, white smoke rose from the entire venue.

This is the water vapor evaporated by quicklime soluble in water and heated.

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 membrane appeared on the water surface of the sink, and some students collected it.

At the same time, some students have heated the meat oil.

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

Immediately, they added salt.

Soon, a white solid appeared in the glass jar.

The students lifted up the glass jar, covered a clay pot with cloth, poured the contents inside, leaving solids on the cloth, and liquid flowed into the clay pot.

Finally, press the solid on the cloth into molding and drying.
Chapter completed!
