Start Being a Vassal King Today - Chapter 356

[Chapter 356 New Thing]

“Your Highness, this cannon has just been built, and I will try cutting it with a hydraulic boring machine immediately.”

There is also a fixed cannon in the workshop.

The cannon was also fixed on a wooden frame.

The centerline of the muzzle is consistent with the centerline of the boring tool.

Just push the wooden frame towards the boring machine and the cutting can start.

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

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

When the drill press drills the 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 and tear cannot be avoided.

The same is true for boring machines, and even lathes that will be used later will need this lubricant.

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

“Yes, Your Highness.” Wang Ying said.

After ordering this matter, Zhao Xu went straight to the Science and Technology School.

He wasn’t overly excited.

Because the hydraulic drilling machine has accumulated technology for it.

Now it’s just a matter of course.

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

He was dull, but not stupid.

He never promises anything he is not sure about.

Arrived at school.

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

Let them write 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 have been able to flexibly grasp various formulas and scientific concepts.

To communicate with them, you don’t have to explain everything to them.

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

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

Many practitioners even lit the lamps and read until midnight.

At this stage, Zhao Xu felt that it was necessary to give these students a chance to make 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 also plays an important role. After all, the higher the technology, the more calculations are needed.

This is a basic science, and even though the benefits will not be seen in a short period of time, it is necessary to spend money to train such talents.

“The king said that he would give you a task. Now this task is coming. The saponification reaction. The king told you about it. Now you are in a group of ten people. Within a day, the king will see the finished soap.

” After a while, he continued: “Now, you should divide into groups first, and each group will give me the materials it needs, and I will provide them to you. Each group cannot communicate with each other, and each group depends

on its own ability.” An assessment practice for the students.

Allow them to complete the manufacture of the same chemical alone.

To expand, this is a chemical production line.

“Yes, Your Highness.” Zhao Xu’s order did not make the students fade away, but they were all gearing up.

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

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

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

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

In response, the students moved.

Not long after, the three hundred and twenty-two students were divided into thirty-two groups.

There are eleven people in two groups.

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

With a smile, he returned to his seat.

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

He just stared at the school, responsible for his own study, and urging the students to study.

Wang Ying did not allow him to do anything else.

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

Wang Chong was a little displeased at first, but after being exposed to the vast amount of knowledge in the textbooks, he immediately fell into it and couldn’t extricate himself.

The arrogance he had at the beginning also disappeared completely.

He knew very well that if he didn’t study hard, he would be replaced by the students in the school in a short time.

Wang Chong handed it in, the second one squinted, and the innocent student handed in the list.

Zhao Xu smiled lightly.

The student’s name is Qu Sheng.

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

In the last official examination, his numerology was a perfect score.

And it turned out that he was a natural science student.

Physics and Chemistry are equally good.

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

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

But it’s mostly true.

Unsurprisingly, this unqualified list belonged to the craftsmen’s children.

Due to illiteracy, the craftsmen’s children have poor foundations, and they must first read before they can read through the textbooks.

So they learn very slowly.

But Zhao Xu didn’t intend to give up on them because of this.

These craftsmen’s children are also very hardworking.

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

Call a group of students who made mistakes 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 fetch meat oil, quicklime, soda ash, and salt, and he also sent people to the glass workshop to fetch a glass jar with a diameter of 30 centimeters.

In the afternoon, all these things were ready.

Zhao Xu didn’t participate, just moved a chair and sat on the side, watching them toss.

See how they synthesize materials from scratch to make soap.

“Pour quicklime into the water tank, dissolve it, and then add soda ash.” Wang Chong assigned tasks to the students in the group methodically, five meters away from Zhao Xu.

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

The students are familiar with it, and at the same time understand the reason why Wang Chong asked them to do so.

After a while, billows of white smoke rose from the entire field.

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

When a clear solution appeared in the sink, 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 have already heated the meat oil.

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

Immediately, they added salt.

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

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

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

In the evening, each group handed soap to him one by one.
