Become a feudal king from today

"Your Highness, this artillery piece has just been built. I will try cutting it with a hydraulic boring machine right away. ReadМ"

There is also a fixed cannon in the workshop.

This artillery piece was also mounted on a wooden frame.

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

Simply push the frame toward the boring machine and cutting can begin.

Zhao Xu nodded, then looked towards the boring machine.

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

When the drill press drills the gun barrel, the drill bit needs to be lubricated with lard, otherwise the drill bit will be more easily damaged. After all, the problem of wear is unavoidable.

The same goes for boring machines, and even lathes that will be used in the future will need this kind of lubricant.

"Well, if the effect is good, I will bring back the artillery in the army and cut it again. Then you can test the power and range of the cut artillery." Zhao Xu patted the artillery. This is another task.

"Yes, Your Highness," the king responded.

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

He wasn't overly excited.

Because the hydraulic drilling machine has already accumulated technology for it.

Now it's just a matter of course.

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

Although he is dull, he is not stupid.

He never promised anything he was unsure of.

Arrived at school.

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

Ask 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.

"See Your Highness." Everyone shouted together.

Looking over the students one by one, Zhao Xu felt a sense of accomplishment.

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

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

You don’t have to explain everything to them when communicating with them.

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

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

Many students even lit up their lamps and studied until midnight.

At this stage, Zhao Xu felt it was necessary to give these students a chance to come up with something on their own.

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

As for mathematics, it naturally plays an important role. After all, the higher the level of science and technology, the more calculations are needed.

This is basic science, and although it may not see benefits in a short period of time, money must be spent to cultivate such talents.

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

After a pause, he continued: "Now, you will be divided into groups first. Each group will give the required materials to me, and I will provide them to you. Each group cannot communicate with each other, and each group will rely on their own abilities."

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

Allowing them to complete the manufacturing of the same chemical alone.

To expand further, this is a chemical production line.

"Yes, Your Highness." Zhao Xu's order did not make the students retreat, but instead geared up one by one.

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

After all, King Yan personally demonstrated one experiment after another and cracked many things they thought were magical spells.

Facing the rich content in the textbook, the door to a new world slowly opened in front of them.

They are happy to use their own hands to turn teaching materials into real objects.

In response, the students started to move.

Soon, the three hundred and twenty-two students were divided into thirty-two groups.

There are two groups of eleven people.

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

With a chuckle, he returned to his seat.

Since the establishment of the Science and Technology School, the research and development matters in the War Division have basically nothing to do with Wang Chong.

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

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

In his opinion, it is much more important to let his son attend school than to assign him some work.

Wang Chong was a little unhappy at first, but after being exposed to the vast knowledge in the textbook, he was immediately immersed in it and couldn't extricate himself.

All the arrogance I had at the beginning has completely disappeared.

He knew very well that if he didn't study hard, he would be replaced by the students in the school before long.

Wang Chong handed it over, and the second student, with squinting eyes, handed over the order.

Zhao Xu smiled softly.

This student's name is Qu Sheng.

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

In the last official examination, his math skills were perfect.

But later it turned out that he was a natural science student.

Physics and chemistry are equally good.

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

Among the thirty-two lists, only one was missing a certain item of information.

But it's generally correct.

Unsurprisingly, this unqualified list belongs to the craftsmen's children.

Due to illiteracy, the craftsmen's children have a poor foundation. They must first learn to read before they can read through the textbooks.

So they learn slowly.

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

These craftsmen’s children also work very hard.

When he gave them hope, he gave hope to all the craftsmen.

Call a group of students who have done something wrong to come over to criticize and make corrections.

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

Then he ordered Wang Ying to send people to get meat oil, quicklime, soda ash, salt, and also sent people to the glass shop to get a glass jar with a diameter of 30 centimeters.

In the afternoon, all these things were ready.

Zhao Xu did not participate. He just moved a chair and sat on the edge, watching them.

See how they synthesize materials from scratch and make soap.

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

Professional words kept popping up in his mouth, which are all from the textbooks.

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

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

This is the water vapor that is evaporated when quicklime dissolves in water.

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

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

At the same time, some students were already heating meat oil.

At this time, the students poured the collected white film into the hot oil while stirring continuously.

Immediately, they added salt.

After a while, a white solid appeared in the glass jar.

The students lifted up the glass jar, covered the mouth of a clay pot with cloth, and poured the contents down. The solids remained on the cloth, while the liquid flowed into the clay pot.

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

In the evening, each group handed him soaps one by one.
