Southwest of Bac Ninh Province, Ao Fort.

Tang Ruowang was here and saw Yang Chengying again.

"Jinglu, my friend, how did you have time to come here?"

John Tang opened his arms and greeted him with a smile.

Yang Chengying hugged him and responded: "The church in Bac Ninh Mansion has been completed, and I specially invite you to unveil it." ”

In ancient times, there were also unveiling ceremonies, and the rituals were different depending on the object.

Tang Ruowang shook his head with a smile: "Jingluo, you have something to hide from me." ”

"How so!" Yang Chengying denied it with a smile.

"I'm not old, my eyes haven't spent, and I can see the changes here."

In Chinese, John Tang said unhurriedly: "The south side of this iron mine has been sealed by you for several months. There are a lot of things to move in, and a lot of strange people. ”

As early as the eve of Yang Chengying's troops, he instructed Liu Tianlu to lead Xiong Wei's battalion to blockade the area north of Nanshan and south of Fort Ran.

Artisans built a fence around the perimeter of the area and built rows of houses.

The movement is so loud that everyone can see it.

"I'm useful, but I can't be honest with you."

Yang Chengying said: "This is a senior secret of my town, and it will never be passed on." ”

"I know that many of my colleagues are spies sent to you by my country."

Tang Ruowang defended anxiously: "But I'm not." Of course, before I met you, I also reported the situation to the church in my country.

But since you awarded me that medal, I haven't reported it. ”

"It's not a matter of whether to report or not, but a major matter related to the fortunes of the country."

Yang Chengying said sincerely: "If you really want to know, then the church has to be closed, and you can't leave here for half a step." ”

When John Tang heard this, he drew a cross on his chest without thinking about it, and swore to the West: "If I reveal half a word, or leave half a step, let me go to hell." ”

He already sensed that something big was about to happen, so he was curious.

Unlike some missionaries, John Tong was more interested in scientific inquiry than he was loyal to the church.

Like him, there was the late Matteo Ricci.

Yang Chengying also confirmed this through long-term observation before telling him.

"In that case, don't blame me for turning the church into a warehouse."

Yang Chengying said humorously.

John Tang nodded.

Compared with the church, he was more curious about what Yang Chengying was going to do.

"Come with me, I'll take you to a good place."

Yang Chengying said goodbye and walked in front.

John Tang hurriedly followed.

The two of them came to the south of the iron mine, the area that was cordoned off by the soldiers.

The soldiers pushed open the gate, and there were already a lot of people gathered inside.

They were also confused, not knowing what they were doing here.

As soon as I saw Jingluo, I greeted him one after another.

Mao Yuanyi, Sun Yuanhua, Song Yingxing, etc. are among them.

There are also a large number of skilled workers and technicians such as Qi Dazhuang, Wang Tianxiang, and Jin Shixiang.

"Ladies and gentlemen, I'm sure you're wondering why I brought you here."

Yang Chengying stepped onto the high platform and said loudly: "I did this because this place will be remembered forever by future generations in the future." ”

Everyone looked at each other and became more and more curious.

Yang Chengying said: "Many of you have read books in your free time, especially history books. The above records are all emperors and generals, and there are very few people.

But that is only the past, and in the future, your name will be engraved in the history books with me, immortal! ”

At this time, everyone realized that something big was about to happen.

A big thing they couldn't even think of.

"In order to maintain secrecy, we use 630 as the code name, no matter who asks you, you only say that you are ordered to participate in the 630 project."

Yang Chengying said: "Remember? ”

"Remember!" The crowd responded in unison.

"It's too quiet, answer me again." Yang Chengying said loudly.

"Remember! Live! Finish! Everyone yelled with all their might.

Yang Chengying nodded with satisfaction.

He turned his head to Song Yingxing beside him and said, "Open it." ”

"Yes."

Song Yingxing stepped forward, opened the box placed at Yang Chengying's feet, and worked with Ding Qiming to lift a scroll of drawings from inside.

In front of the crowd, they pulled the scroll open and put it up again.

Everyone looked at the contents of the cloth, their eyes widened and they were shocked.

Because they know the three words written in the upper left corner of the picture - steam engine.

Underneath the big letters, is a mechanical structure diagram that they have never heard of or seen.

The level of sophistication is no worse than a flintlock pistol.

There are even some parts that are completely confusing.

"Oh God."

Tang Ruowang subconsciously drew a cross in front of him, and his pupils dilated in shock.

"The full name of the machine in this picture is the reciprocating steam engine."

Yang Chengying introduced: "The principle is very simple, just like boiling gas can open a teapot, but it is difficult to do. ”

Everyone was still confused.

"It doesn't matter if you don't understand, you just need to know that there is it!"

Yang Chengying emphasized: "You can quickly go to a long distance without relying on cattle and horses and other livestock, and you don't need to rely on your own feet." ”

"Is it an immortal?"

One person asked curiously.

As soon as he spoke, everyone laughed.

"It's not!"

Yang Chengying said affirmatively: "However, the one who can make this thing is an immortal." ”

The working model of the steam engine can be traced back to the late seventeenth century, by the French physicist Denis Papin.

This dude also invented the world-famous pressure cooker, which is still used today.

At the beginning of the eighteenth century, the first early industrial steam engine was built.

It wasn't until seventy years later that Watt modified the steam engine, which doubled its thermal efficiency and greatly reduced coal consumption.

The first industrial revolution that changed the history of mankind arrived.

After that, it took Watt nearly two decades to create the molded model.

In other words, if Yang Cheng should come step by step, he will not be able to take the train in this life.

To do it in one step, the method that Yang Cheng should adopt is to give full play to the unique method of the ancient empire and concentrate all his forces to do things.

Led by the Academy of Sciences, the Academy of Resources Management, the Tiangong Bureau, three ordnance bureaus, two iron ore plants, one coal mine, and one copper mine are united.

Thousands of skilled workers from various positions are gathered together.

There are also women workers in textile mills, who are involved.

According to the parts part, the same set of standards is used to produce separately in different departments, and then assemble and merge.

Throttle valves, rational governors, steam valves, steam boilers......

In short, it takes a huge investment.

There is also a diagram for each part, which is marked with numbers, and the standard of error is clear.

From that day on, Yang Chengying was almost soaked in the 603 base.

He and Mao Yuanyi traveled around various departments, using self-made calipers to determine the error.

Sun Yuanhua, Song Yingxing, Tang Ruowang, Wang Tianxiang, Jin Shixiang, and others with practical experience are each responsible for a department.

The army and government affairs were handed over to Zu Dashou, Fan Wencheng and others.

He only took the time to write a good report, playing Emperor Chongzhen.
