Bureau of Ordnance.

"Let's wait for a long time today." This is what Zhu Yuanzhang said to the ministers before he came, and then he took the civil and military officials to the Ordnance Bureau to watch the steam turbine loom that had been made.

At this time, outside the Ordnance Bureau, there was already a textile machine, and more than a dozen craftsmen were standing neatly next to the new machine.

The steam turbine textile machine has a spinning pendant, a spinning wheel, a spindle, a pedal and ......

The structure is similar to that of a traditional textile machine, but it is made of iron.

There are 20 spindles in total, indicating that it is a large workshop loom rather than a home loom machine. There are up to five spindles for textile machines used in ordinary households, which belong to the small category.

The textile industry of Daming is the most developed in the Jiangnan region, which does not mean that there is no spinning and weaving in other regions.

On the contrary, there is a textile industry in almost every province, but the scale is far less than that of Jiangnan, which belongs to small family production and can meet its own needs. And the technical aspect is not as good as Jiangnan, and the local spinning yarn cannot be spun.

Unlike traditional looms, this "iron guy" is equipped with a shiny iron lump.

There is also an iron pipe connected to the boiler room.

Although it is relatively simple, it is rare to achieve this degree with the craftsmanship of the Ming Dynasty.

"I've seen this kind of large-scale textile machine, and almost all of them are found in textile workshops in Jiangnan." An official from Jiangnan said to his colleague next to him, "But the looms in Jiangnan are all wooden structures, and I have never seen them made of iron."

"Could it be that the new type of loom that the emperor asked us to see was just changing wood to iron?" The official next to him said.

"Changing wood to iron is too heavy to be transported, and it's completely unnecessary." Another said, "And it is easy to rust when exposed to water, and it is easy to pollute the silk thread."

"You don't understand that." Li Shanchang said, "Now that I have learned the blast furnace steelmaking technology, the steel will not corrode."

"Why haven't I heard of blast furnace steelmaking technology, could it be that the person taught me?" Jiangnan officials hurriedly asked.

Li Shanchang did not answer when he heard this.

"It's not just about changing wood to iron." Another Jiangnan official said, "Xia Guan has personally been to the textile workshop in Jiangnan, and although the textile machine in it is similar to this textile machine, it is still very different, such as the iron lump and the iron pipe."

Although they were born in Jiangnan, they have really been to the textile workshop and do not know much about the structure of the textile machine.

Jiangnan weaving, do not necessarily know the textile machine.

"Your Majesty, can you start?" The craftsman next to him asked.

"Hmm." Zhu Yuanzhang nodded.

The steward of the craftsmen received the will and began to direct the craftsmen to operate.

Smoke rose from the boiler room, and the craftsmen began to boil water. The boiler stove was burned red, and the big-shouldered and round-waisted craftsman was bare-chested, throwing a shovel of coal into it. The craftsman in charge of the ancient style next to him began to pull the blower hard, and the coal in the stove was burning, and the temperature rose rapidly. "Add to the fire!" "Intensify the blowing!" "No!"

In less than half an hour, with a bang, a white mist came out.

The water is boiled, and the water vapor, which carries a strong heat energy, is introduced from the duct into the steam turbine.

The vapor is converted into powerful kinetic energy in the steam turbine through the change in air pressure.

"Woooooooo

The pulleys of the steam turbine spun at a speed that was almost invisible to the naked eye. This group of ancients did not know how to control the temperature, so they increased everything to the maximum and made the steam turbine to the maximum power.

"Crunch!" "Crunch!"

Drive the textile machine to start spinning automatically.

At this moment, the ministers of civil and military affairs fell into a dead silence.

"This thing works on its own without anyone operating it?"

"Could it be that there are invisible imps to help?"

"It's weird!"

In the ancient perception of the crowd, someone has to exert force to make things move.

Now this loom is free of any human operation and it can spin automatically.

This can't help but make some people suspect that there are ghosts or gods who are operating this machine invisibly.

In the ancient folklore, the conch girl also secretly came out to help him wash and cook after the young man left, and I didn't hear that the conch girl hid her body and helped him wash and cook in front of him.

The machine moved on its own, giving the crowd a strong shock inside.

"Start spinning!" The craftsman stewards.

Soon, several skilled female weavers sat down on the workstation and began to skillfully extract silk threads and spin them into cloth.

"This textile efficiency is hundreds of times that of manual labor!"

"The amount of work that used to be done by dozens of workers in a day, this machine can complete it in a few moments!"

"And it doesn't take a lot of manpower, so I don't get tired of doing this kind of work all day."

……

The ministers were talking.

"It's not some god operating the machine, and it's not a ghost helping." After hearing the ministers' discussions, Zhu Yuanzhang popularized science to the crowd, "This is called technology! It uses steam as a power source and converts it into mechanical energy."

"We're using the water vapor from boiling water to help us do things, not some fairy spirit."

"May I ask the emperor, how can water vapor help us do things?" A minister asked.

"Why not? The wind can blow things around, and we can't see them. Could it be that the wind blew away the clothes, and the gods did it?" Zhu Yuanzhang said, "Using the power of water vapor and using the wind of nature is the same truth."

"Water vapor can push the lid of the pot, and it is also powerful. It's just that in the past, everyone thought that the force of water vapor to push the lid of the pot was very small, and its role was ignored by everyone."

"It's called a blind eye that can't see Tarzan."

"I see!" The ministers suddenly realized.

Seeing that the ministers looked like they had never seen the world, Zhu Yuanzhang also experienced the happiness of Qin Yu going to remote areas to teach at this moment-bringing advanced satisfaction to backward areas.

"But the power of the water vapor pushes upwards, and the spinning machine moves back and forth......" At this time, another courtier questioned.

"That's where mechanical movement comes in." Zhu Yuanzhang said, "This kind of knowledge, our princes know, because they have been learning from Mr. for a long time, our culture is not high, although we have a lot of contact with Mr. Qin, but we have not yet comprehended the mystery of mechanical movement."

"This is simply the knowledge of the gods!"

"Isn't letting the loom weave itself the same as the gods helping?"

"This kind of knowledge is comparable to that of a god!"

The ministers were all envious, the princes and princesses of the Ming Dynasty could learn immortal knowledge from Mr. Qin, but their children and grandchildren, and the children of the family did not have that opportunity.
