The craftsmen laboriously put together two large iron balls on the ground, and coated them with a sealing ring doped with rubber paint and gum.

Fu Wansan, the master craftsman, personally applied wax to the inner ring mouth.

After carefully inspecting all the places, he waved his hand and let the disciples and grandchildren move quickly and in one go.

In the clearing, there are very reinforced wooden shelves made by carpenters.

Iron rods were used as flat poles, and iron balls were nine inches long, because they were filled with water, which was more laborious.

No one dared to be careless, lightly with his neck showing his green tendons, gritting his teeth and slowly lifting it to the wooden frame.

Zhu Gaochi couldn't help but come over, watched Wansan open the valve with his hands, aimed at the water suction device and began to pump water, and asked, "Does it matter?" ”

"Go, go, don't mess around." Wan San looked ahead, and didn't look back, not knowing that it was the eldest prince who was asking, and thought it was a curious common man.

His apprentices looked horrified, for fear that the master would cause trouble.

Probably sensing the abnormal atmosphere, Wan San subconsciously turned around and saw Zhu Gaochi behind him.

With a shake of his hands, he almost dropped the suction device to the ground.

"Grass...... Grass people. ”

Wan San was pumping water, hesitating whether to interrupt the work in his hand and kowtow to the eldest prince to apologize.

"Let's take a look, don't dare to disturb the master." Zhu Gaochi hurriedly waved his hand and said.

First of all.

Craftsmen were not free in the Yuan Dynasty, they belonged to slaves, and they were wantonly killed

Secondly.

The blood of the Han people is still there.

On the surface, he can't resist, and when he is doing work in his hands, he can make the Yuan Dynasty grow a big heel with a little bit of hands and feet.

For example, the Yuan Dynasty went to sea twice to conquer Japan, both because of the problem of ships, and when they encountered waves, they capsized.

Twice, the great armies of the Yuan Dynasty were completely annihilated.

The Yuan Dynasty no longer trusted the Han craftsmen and moved the shipbuilding workshop to Korea.

Brought advanced shipbuilding technology to North Korea.

However, advanced productive forces are not so easy to learn.

The current Da Ming.

The restrictions on craftsmen were relaxed, and except for the time spent serving the government, the rest of the time was left to the craftsmen to produce freely in the people.

It not only restored the freedom of craftsmen, but also improved the living standards of craftsmen and promoted the development of craftsmen.

At last.

The king of Qin next door abused the people, and it reached Zhu Yuanzhang's ears, and he ordered the prince to go to Shaanxi to supervise the case.

At this time, the crown prince was in Xi'an Mansion in Shaanxi.

In case the third is an old craftsman of the Yuan Dynasty, so are his apprentices.

So there is a fear of the powerful.

But the case of King Qin is in the past, even the vassal kings are like this, not to mention him, Zhu Gaochi really doesn't dare to offend the craftsmen.

At least don't dare to do anything wrong.

One asks for them, and the other has a grandfather staring.

"We are grateful for handling this well."

Pointing to the iron ball, Zhu Gaochi said with relief.

Wan San breathed a sigh of relief.

His apprentices and grandchildren are also becoming more and more meticulous, and they all hope to do a good job so that the nobles will not pursue their ancestors.

The ground was wet with water.

Iron rings poured at both ends of the iron ball are put on iron chains.

There were eight horses on each side, and the riders on the horses were ready, waiting for an order.

Can the strength of sixteen horses pull the iron ball?

The surrounding people are looking forward to it, waiting for the nobles to make a fool of themselves.

"It's a pity that we don't open the market, otherwise we have to make a bet."

"The person who opened the gambling house is not a fool, and he can't spend the money for nothing."

"They're all a bunch of thieves."

Even the gambling house is sure that it will fail, let alone the people.

No one thinks that the nobleman will succeed.

They waited to see the joke.

The nobles are high in the mountains, and I heard that every meal is a delicacy of the mountains and the sea, and the common people like to watch the nobles make a fool of themselves.

Wan San finally checked it, confirmed that there was no problem, and nodded to the people from the Yan Wangfu on the side.

The flag is down.

The horses' front hooves moved, and with the movements of the knights, they began to move forward, and the iron ball was easily pulled up and suspended in the air.

Zhu Gaochi's eyes didn't blink, and he stared at the iron ball in a daze.

This experiment was the first time he had done it.

The reason why this experiment was done was because of the Industrial Revolution.

This year is the best time to go.

Because after this year, the crown prince Zhu Biao will die.

The crown prince is dead.

The father of the original owner of this body, that is, Zhu Di, will live very cautiously.

To be exact.

All of Zhu Yuanzhang's adult sons will not dare to publicize it in the next few years.

When the eldest brother of the vassal kings was still there, their life was not bad, and if Zhu Biao was not afraid of them, no one could suppress them.

When Big Brother is gone.

People began to keep an eye on the vassal kings.

The industrial revolution ran counter to the national policy of emphasizing agriculture and suppressing business.

The prince is dead, but he dances so happily, are you afraid that others will not see you and covet the prince's position?

Don't say that Zhu Gaochi can't bear it, even his old son Zhu Di's big body can't bear it.

Under the general environment.

Everyone had to wait quietly.

Whoever is not quiet will cause great trouble.

Only when the crown prince is still alive will the matter be implemented, and there will be no tongues in the future.

It was only before Zhu Di's return from the northern expedition that Zhu Gaochi made visible achievements, so as to obtain his father's support, so that he could continue to develop industry in the future.

Without his father's support, Zhu Gaochi couldn't do anything.

Even if you convince your mother, you can't do it.

Under the imperial power, all living beings are worried.

Even if the dust settles on the throne of the crown prince, not only can he not start to develop industry, but he will have no opportunity.

It won't be long before the new emperor will cut the domain.

Zhu Di, the king of Yan, will rebel.

Then.

It's the second brother's world.

The era when the god of war was born.

Zhu Di, who was attacked by an army of 500,000 and had no success, personally hinted that if he conquered the world, let him be the prince.

The second brother is Zhu Di's Dinghai Divine Needle.

Zhu Gaochi didn't know how the original owner solved these problems, and according to historical knowledge, it was not a complete solution.

The risk is not small, and the proportion of luck is higher.

I don't know the original way, and I can't go through.

The only way to survive is the Industrial Revolution.

Only the mastery of industry.

No one can defeat him Zhu Gaochi.

is the real invincible.

Only industry can explode.

Crush agricultural civilization.

And it was this experiment that would determine his future.

It worked.

can get the mother to support herself.

Now the head of the family in Peking is Princess Yan.

Not only is he full of poetry and books, he is able to excel, but he can also participate in the military and defend the city in armor.

"It really doesn't seem to be able to pull it?"

Distance.

The people were dumbfounded.

"We're not dazzled."

Sixteen riders tried to control the horses under them, but no matter how hard the horses tried, they could not move forward.

"Mother, my brother succeeded."

Zhu Yuying said happily.

Princess Yan's eyes were complicated.

Yanwangfu will not lose face.

Bet with the eldest son, if the eldest son fails, he will study honestly in the future and stop thinking nonsense.

Glad? Yes.

Lose? There are also.

The son is up, and he can't help it.

"Why can't it be pulled open?"

Shi Gecheng, the head of Yanwang Mansion, rubbed his eyes vigorously, unable to believe what his eyes saw.

Through a successful experiment.

Zhu Gaochi persuaded his mother.

It also proved to the craftsmen that the atmospheric pressure he spoke of existed.

Since the atmospheric pressure has been proved, seeing is believing, then the principle of the steam engine is clear to the craftsmen.
