The steam engine moved very slowly, but it did.

The steam engine designed by Yan Ming is a reciprocating steam engine after perfection.

With the movement of the steam engine, there was a whining sound, and Yan Ming's face turned red.

Others just wondered, how did that piece of iron move? In front of Yan Ming is an industrial revolution that has advanced many years.

An invention is an invention, and an application is an application.

From invention to application, a thing always has to go through a period of debugging tests.

This is not so difficult for a person who is born with a love of machinery.

Today's Cloud City has become a fortified city in the north of the Han Dynasty, and there is a blacksmith battalion headed by the elder Chen. You can do an experiment.

Yan Ming's bold idea suddenly popped up.

"Keep it moving, don't stop, keep adding fuel." Yan Ming said.

Elder Chen immediately beckoned someone to add pieces of wood to it.

"Don't make wood, use your iron-making briquettes." Yan Ming said.

"Get the briquettes, hurry up and get the briquettes." Elder Chen shouted, and immediately someone ran over and took briquettes and added them to it.

The fire of the briquettes lasts longer, and the heating water lasts longer. Steam is constantly generated, and the reciprocating motion of the transmission shaft of the steam engine is getting faster and faster.

By the end, the sound of clanging was almost incessant.

"This thing is used to hit the city gate when it is attacking the city, and it must be faster than the human man." Elder Chen said with a smile on the side.

Yan Ming nodded, but Wei Qing looked at the roaring steam engine and said, "This is no longer as simple as hitting the city gate. It's iron into fine. Have no bottom! ”

"This is a big deal, my brother writes a report or do I write a report to His Majesty the Emperor?" Yan Ming said.

"It's your main focus. I'm not going to get involved. It's better for you to write a report to His Majesty the Emperor. Wei Qing said.

Yan Ming nodded, he really had to say it himself.

He wrote a note to Liu Che on the same day. The operation of the steam engine was written in detail, and the influence of the steam engine on the future was briefly explained.

After Song Shu sent him away, Yan Ming hid in the county guard's mansion.

At this time, the county guard mansion had been requisitioned by Wei Qing.

Yan Ming asked for a study and asked Wei Qing to send a few soldiers with fast legs and minds to follow him.

After working in the study for a whole night, a transmission shaft and iron wheel that conformed to the craftsmanship of this period were pounded out by Yan Ming.

This is the simplest wheel, and Yanming replaces sliding with simple scrolling. It's in the axle part, but it's obviously not as precise as the bearing.

However, compared to this dynasty, it is already a very advanced design.

"Take this to Lao Chen and let him see if there is any difficulty in making it." Yan Ming sorted out the drawings and wanted to give them to the followers. After thinking about it for a while, he shook his head and said, "No, I still have to revise it again." ”

It's another two or three days of busyness, and I can't reach it without sleep.

He just sleeps when he's sleepy and wakes up and starts working. The whole axle system has been modified to make it simpler and smaller.

In the end, it was Yan Ming himself who gave this drawing to Da Lao Chen.

After seeing this set of axle transmission system, Da Lao Chen showed a surprised look on his face. After so much time, he concentrated on the steam engine, and he understood a lot about the mechanical things.

"Wouldn't this, if it be connected to a steam engine, turn on its own?" Elder Chen's eyes lit up and said.

Yan Ming nodded and said, "All this must be kept highly confidential. And it was done. Your bounty is guaranteed. ”

"Good" Da Lao Chen also became excited.

In the days that followed, the blacksmith camp was like a chicken's blood.

In addition to the daily production of flintlock pistol parts, Da Lao Chen selected more than a dozen craftsmen with better craftsmanship and began the arduous process of building the wheel linkage shaft.

Yan Ming kept debugging the steam engine. Through various controls, the reciprocating speed of the steam engine can be changed.

Liu Che replied to his song and sent it, so that he could study the steam engine in Northern Xinjiang with peace of mind. The development on the Southwest Yi side is underway, so don't worry about it.

Yan Ming didn't worry about it at all.

His first priority now is to get the steam engine right and develop the axle system. Next, his target is Xianbei's side.

There is a big oil field there.

As long as you get oil, you can refine gasoline and diesel......

In addition to the blacksmith camp, Yan Ming went to the school in Cloud City the longest.

The school here, built by Lao Xu, is almost exactly the same as Hongyan Hall.

The gentleman inside is still simply handing over the children to read and write. Arithmetic, it's just simple addition and subtraction.

In school, Yan Ming found the children of the Huns.

After asking Wei Qing, I learned that in the current Yunzhong City, a part of the Xiongnu prisoners of war and refugees were accommodated. As long as they were sincere to the Han Dynasty, Wei Qing gave them the household registration of the Han Dynasty.

In this way, their children could study in the Han Dynasty schools.

These herders don't know the use of reading and writing, they only know how to give birth to babies, herd sheep and marry daughters-in-law. But since the Han Dynasty demanded literacy, they had little more objection.

Later, when they heard that after the children read and write, they might become officials in the Han Dynasty, so the herdsmen were happy to let the children read and write.

Wei Qing is actively preparing for the war.

Now the war between Yu Shan and Yi Zhixie is coming to an end. Both sides were exhausted from fighting.

Most of the Huns in the steppe were refugees, and the number of Huns was drastically reduced by the war.

After a while, the Xiongnu will probably collapse on both sides.

At that time, it was the time for Wei Qing to show his might.

Before, Wei Qing never thought that the rhythm of other countries' wars could be controlled in his own hands.

He was originally a master of strategy, and now the two kings of the Huns are controlled, and they are handy in fighting for the throne alone.

The momentum Yi Zhiyi had already seen the methods of the Han Dynasty, and had also contacted Yu Dan to end the war.

But Yu Shan did not retreat, thinking that the Xiongnu State should have been his, and he had to do it.

Yi Zhiyi and Yu fought singles to almost lose both, and at this time, even if the truce was divided, it was a land division. It is impossible for him to be completely obedient to Yu Shan, and if that is the case, his death will not be far off.

Knowing that there are tigers in the mountains, he prefers to go to the tiger mountains. It's a hero's statement.

Knocking out the tooth and swallowing it in the stomach is a nest bag.

Either way, the parties are not happy.

Especially Yi Zhixi, who saw the truth of the matter, but couldn't stop the war.

"Han people, so insidious." Yi Zhi scolded and beaten. didn't know that Wei Qing was ready to attack.

It took a full month for Yan Ming's drive shaft to be considered ready.

It looks a little rough, but you can give it a try.

Seeing that the steam engine was connected to an axle system, Yan Ming's heart fluttered, and he was afraid that there would be a loophole in his design.

Now, this thing is like his child, and nothing can go wrong.
