Rich and powerful

"This is a steam engine and the most common machine tool, which can greatly improve the efficiency of making copper and iron bullets! Although it is very difficult to manufacture, it will be difficult this time. It will be easy to make copper and iron bullets in the future! Come on! Let's Just work hard!!"

As he spoke, Lin Yun heated up the blast furnace in the operation room, and threw several large pieces of iron into the crucible.

And Yang Tiexin was watching from the side. After all, he didn't have the mind of a Lin Yun traveler, so he still couldn't understand new things.

He couldn't believe that the sketch that Lin Yun drew casually could be produced.

Although it seems small, Yang Tiexin knows that the smaller the parts, the more difficult it is to manufacture, because some small places are difficult to touch even by hand, and the difficulty can be imagined.

Lin Yun has also thought about it recently.

In his previous life on Earth, although he had never seen how military factories used machine tools to make bullets, he had studied steam engines and machine tool blueprints, and probably understood the principles.

And there is no electricity in this world, even if he makes a machine tool, he still needs to find a way to provide power for the machine tool.

After much deliberation, he decided to use a steam engine.

Although the steam engine consumes a lot of coal resources and pollutes the environment, but now Lin Yun has no better way.

For him, it is not difficult to make a simple steam engine, but the difficulty is that the manufacturing process will be very laborious.

Because all the parts required must be sufficiently precise.

Soon, the first furnace of molten iron was smelted, Lin Yun took out the crucible, and made a mold of a pressure cooker out of the mud.

The most important thing about a steam engine is to use steam as power.

And ordinary steam pressure is not enough.

Therefore, Lin Yun first made a pressure cooker. In a completely sealed state, the steam in the pressure cooker is extremely powerful. Once it explodes, it can even kill people.

Seeing Lin Yun's serious face, Yang Tiexin was also greatly encouraged, and asked, "Mr. Lin, what can I do for you?"

"You help me smelt all these iron lumps into molten iron first! Then wait for my next order! Also, keep your eyes open to see clearly how I operate. What I have taught you is a unique technology in this world!"

Yang Tiexin nodded hastily.

How capable Lin Yun is, he has already experienced it.

Therefore, he was full of confidence in whether Lin Yun could produce what was shown in the sketch.

The only thing that made him doubtful was the difficulty.

As an old blacksmith, he had dealt with iron all his life, and he could tell at a glance that the thing Lin Yun wanted to forge was extremely difficult, and the level of precision was unheard of by him.

If it takes a year and a half, it may be successful, but it is completely impossible for him to manufacture it within a few days.

After that, Yang Tiexin stared at the operation in Lin Yun's hand while calcining the molten iron.

After the mold dried and hardened, Lin Yun poured molten iron into the mold, and thick smoke billowed out immediately.

Lin Yun immediately took out a damp cotton cloth to cover his mouth and nose.

These gases can cause great harm to the human body.

Outside the door, Lin Wuyue and the four girls looked at the smoking operation room with curious faces.

They never imagined that the world's first steam engine would come out soon.

No one knows how much influence this steam machine had on this feudal dynasty.

At this time, Sun Xuemeng came to the door curiously, she really wanted to rush in to find out.

But as soon as she reached out her hand to push the door, Wuna stopped her.

"Fourth Madam, I advise you not to go in! Mr. Xianggong said that only he and Mr. Yang are qualified to enter this operation room now!"

"Tch, we are not outsiders, why do we have to be so mysterious?"

Lin Wuyue smiled and said: "Every time Xianggong does experiments, he can't be disturbed by the outside world! However, it seems that this time Xianggong has researched something amazing!"

Ye Wanqing and Wu Na also looked at each other and smiled.

The three of them have been with Lin Yun for more than a year, and it can be said that they have witnessed how Lin Yun rose step by step along the way.

From the initial manufacture of black powder, to bamboo guns, rain bombs, perfume, fertilizer, and glass.

All of these are the stepping stones for Lin Yun to reach the peak.

Ye Wanqing also said: "That's right, Fourth Madam, if you marry into this family now, then you must abide by the rules of your husband, and don't be as lawless as before!"

As soon as these words came out, both Lin Wuyue and Wu Na fell into silence, only Sun Xuemeng looked a little unhappy.

Ye Wanqing, as the second wife, neither has the power of the eldest lady in this family, nor does she have Wu Na's bold and ungrateful personality.

Moreover, this year, she has the lowest sense of presence in this family.

But no one dared to underestimate her ability.

Ye Wanqing was always able to propose the best decision to Lin Yun at critical moments.

Therefore, Lin Yun has always regarded Ye Wanqing as a treasure.

At this time, Sun Xuemeng curled her lips and said: "Of course I know! However, even if these words are to be said, it must be said by the eldest lady, and the second lady should refrain from doing things on behalf of others!"

"you!!"

Ye Wanqing was furious.

Lin Wuyue quickly pulled her back, shook her head silently, and signaled her not to be as knowledgeable as this little girl.

As the eldest lady, she naturally saw clearly for a long time, and knew that Sun Xuemeng was not easy to mess with.

But Ye Wanqing is also not easy to mess with.

In terms of family, Ye Wanqing's Ye family is also a big family in the capital, and they are not afraid of Sun's family at all.

In addition, Sun Xuemeng used all kinds of dishonorable means to get Lin Yun, which also made Ye Wanqing feel uncomfortable.

She can accept Lin Wuyue and Wu Na, but she can't accept Sun Xuemeng.

In the operating room, Lin Yun didn't know that his four wives had some conflicts again.

He is currently concentrating on melting the pressure cooker.

Carefully take out the mold, the red molten iron has the outline of a pressure cooker.

Lin Yun took out Yang Tiexin's favorite hammer, and tapped it lightly, trying to make it as smooth as possible.

And the handle of this hammer is not big, but the hammer surface is not small.

The advantage of this is that when the red-hot iron is hammered, the force can be evenly applied to avoid uneven consequences.

At this moment, Yang Tiexin said: "My lord, leave this job to me!"

Lin Yun was indeed a bit clumsy, he was not a professional blacksmith after all.

He could only give the hammer to Yang Tiexin with a wry smile.

Yang Tiexin took the hammer, and according to Lin Yun's instructions, he struck skillfully, and the efficiency improved a lot.

Seeing it, Lin Yun was also very satisfied.

About half an hour later, the chassis of the pressure cooker was finally finished and left to cool naturally.

Yang Tiexin asked curiously, "My lord, why does this one you made look like a small pot?"

"Yes, this is a pot, but what I want to make is a pressure cooker!"

"Pressure cooker? What's this for?"
