Emperor Yong'an glared at Chu Xuan, but he didn't stop him, but said angrily: "Be careful!" ”

"Father, don't worry, your son is not stupid!"

After Chu Xuan finished speaking, he reminded the others to retreat, and then he swept the hammer and swung it violently.

"Bang!"

The hammer smashed against the brick wall, making a loud noise, and the huge reaction force shook Chu Xuan's arm numb, but the wall did not fall.

Chu Xuan was a little dumbfounded, and hurriedly said, "That doesn't count just now, I'll do it again!" ”

With that, he swung his hammer again.

This time he used all his strength, and the wall finally cracked, but it still didn't fall, just splashed some debris.

Chu Xuan suddenly felt a little embarrassed.

At this time, his arms were even more numb.

So he thought about it for a moment, and felt that if he continued, it would be too much effort, and even if he smashed the wall, it would not be of much use.

So he rolled his eyes and beckoned to Su Jing: "Su Jing, you come and smash it!" ”

Su Jing: "......"

He didn't want to do this at all!

Don't think he doesn't know, this cement is made in his sister's kiln.

Can something his sister make bad?

What did King Jin ask him to do, he even asked him to smash the wall, was he dissatisfied with him?

Su Jing was very unhappy in his heart, but King Jin opened his mouth, could he still disobey?

He looked at Emperor Yong'an.

After all, he is now working for Emperor Yong'an, and he can't be obedient as soon as King Jin speaks, so he has to ask Emperor Yong'an to do it.

Emperor Yong'an said lightly: "You go and try it." ”

Su Jing took the order and left, took the hammer handed over by Chu Xuan, tried the feel, and smashed the hammer hard.

I heard a loud bang, and the crack in the wall became even bigger.

Su Jing scrambled more than a dozen hammers before he smashed a hole in the wall.

Emperor Yong'an saw it in his eyes, and he didn't show too much satisfaction.

However, when Su Jing smashed open the control group with only three hammers, Emperor Yong'an's face immediately changed.

As the saying goes, people have to die more than people, and goods have to be thrown away. It's not better than not knowing, it's more frightening.

Emperor Yong'an was just scared now.

If it weren't for this tragic comparison, he wouldn't have known that the adhesive he was using now would be so ineffective!

The cement brick wall was smashed so many times, but it was only a hole, and the control group fell down with three hammers.

Could this be a more tragic comparison?

Looking at the collapsed control group, Emperor Yong'an suddenly felt very unsafe.

Almost immediately, he made up his mind to open a cement factory to burn this cement!

At this time, Chu Yan reminded him: "Father, the rest of these haven't been smashed yet." One person is too slow, it is better to call more people.

Su Jing smashed it so much, it is estimated that his arm is sore, it is better to let someone replace him, so as not to hurt his arm. ”

Emperor Yong'an nodded: "Just do as you say." ”

So Su Jing was quickly replaced.

He secretly breathed a sigh of relief and glanced at Chu Yan gratefully.

Next, Emperor Yongan was even more shocked.

Especially when he saw reinforced concrete.

This thing is so sturdy!

He tried it himself, and his arms were numb from the shock!

In the end, a few tall and strong men smashed it dozens of times before smashing it open.

Moreover, although the concrete was smashed open, the steel bars inside were still connected.

Even though they are deformed, they still hold on.

Emperor Yong'an suddenly thought that if this thing was used to build a city wall, the enemy army would finally smash the wall skin, but found that there were still dense steel bars inside, so he would not be angry to death?

The more he thought about it, the more he felt that this thing was good, and he suddenly became more determined to open a cement factory.

And the formula of the cement must be kept secret and must not be leaked.

After watching the cement test, Emperor Yongan took his sons back to the Qinzheng Palace.

He thought about it for a while, and simply sent someone to call a few important ministers and let them take a good look at those cement slabs.

It's best to try it out for yourself.

He then told his sons about the coal stove and the patent division.

When the prince heard that Chu Yan had made it again, his heart couldn't help but feel sour.

However, the patent department is a big deal, so he quickly cheered up and tried to give advice to Emperor Yong'an.

You have to let Emperor Yongan know that he is also very useful, isn't he?

However, he has a lot of opinions about royalties and commissions.

First, he felt that the patent fee should not be too high, and secondly, he felt that he should not charge commissions, otherwise he would be competing with the people for profit.

As soon as he finished speaking, he was given the right thing by Chu Yan.

"Royalties will be set at their own value, and the exact amount should indeed be specified with a set of precise rules to avoid arbitrary pricing.

But this is too ridiculous to compete with the people. Merchants are very profitable, and those businessmen are so fat that they are oily, but many people have difficulty even eating and closing.

Instead of cheapening the gang of unprofitable businessmen, it is better to collect commissions legally, which can not only help the people, but also use them to cover military expenses.

I'm afraid the prince doesn't know that it is not uncommon for people to die for a formula.

But with this patent office, as long as they sell patents to the patent office, or give them carte bli, they can sit back and wait for the money.

However, the patent department has to spend a lot of effort to supervise the merchants, and the world is so big, there must be a lot of manpower.

If there is no commission, is it possible to allocate money from the treasury to support so many people? ”

The prince was so frightened that he couldn't speak, so he had to look at Emperor Yong'an with a blank eye.

However, Emperor Yong'an also had a lot of opinions about him at this time.

He deliberately mentioned this in front of the prince, wasn't it to pull the prince along? Let him rub some merit?

As a result, the prince was good, he actually wanted to dismantle his stage, and felt that he should not charge a commission!

Isn't this to cut off his new wealth?

Emperor Yong'an looked at the crown prince with some displeasure, and asked coldly, "How do you think the treasury should be expanded?" ”

The prince was asked.

Historically, the State Treasury has relied on taxes, especially grain taxes.

Throughout the ages, in order to make money, many corrupt officials and corrupt officials have relied on increasing excessive taxes and miscellaneous taxes, and have constantly scraped oil off the people, causing a lot of complaints.

He can't bring up taxes, can he?

Isn't that spurned by the world?

Thinking about it this way, the prince suddenly felt that there was nothing wrong with charging royalties and commissions.

Emperor Yong'an saw that he was speechless, and his heart was even more disappointed.

The prince seems to be stupid in reading, and he has to go through good training.

Don't know what to say all day long and compete with the people!

Soon, the important ministers came.

They were first taken away, and they were beaten on those hard cement slabs, and when they were all too tired to work, but their spirits were extremely high, Emperor Yong'an asked them to call them to the Qinzheng Palace to discuss the matter of the patent department.

The generals almost all raised their hands in approval.

The more money in the treasury, the more hope for their military spending.

The civil servants are different, some agree, some oppose.

Emperor Yong'an is not in a hurry, if anyone is against it, he will make people think of a better way to make money.

If you can't think of it, you kneel.

This was a very useful solution, and all the opponents agreed to it.
