Behind me is the earth

"It's over at Yun Guifang. After meeting her, don't reveal my identity or the advanced knowledge I gave you. In front of her, I am the shopkeeper of Qixing Trading Company."

Ren Pingsheng stretched his legs, ate watermelon and said: "The war is in full swing in Yinshan County now, and the war may come to us at any time. It has been almost two months, and the Production Bureau has been unable to produce smokeless gunpowder. , This visit to this expert is to solve the problem of smokeless gunpowder."

The boss's words made Liu Wen feel ashamed.

In his opinion, this is as close as pointing at his nose and scolding him for being a loser.

However, he instinctively didn't believe in the master that his boss said.

He and a group of talented people from the Production Bureau have been studying the formula for nearly two months but have not come up with something. What expert can easily solve it?

If something so simple could stump them for so long?

They have tried the things in the formula countless times, and some of them cannot be synthesized at all under the existing conditions!

That expert can do it?

Liu Wen was tired of eating the sweet watermelon, and his mind was in a mess all the way, thinking about things constantly.

Until the carriage stopped at the door of an ordinary courtyard in Yungui Fang.

Several people got off the car one after another.

"Sledgehammer, just bring someone to guard the door."

Ren Pingsheng said something to Chen Dachui, then he went to the door and knocked on the door with his fingers: "Dang Dang Dang~"

"who is it?"

A rough and hoarse voice inside startled Ren Shengsheng.

Xiaowan covered her mouth and almost couldn't help laughing, and explained: "It's Aunt Zhao, the helper hired by Ruan Tang."

Then he shouted from behind the door: "It's me."

"It's sister Xiaowan!"

Ruan Tang's voice came from inside, and his voice was gentle and somewhat heroic.

The door latch was opened, and as the heavy wooden door was pushed open, it hit the copper bell hanging from the lintel, making a clear "ding-dong" sound.

A woman wearing a brown leather apron appeared in Ren Pingsheng's eyes.

Her long hair was tied into a loose ponytail at the back of her head, and she wore loose work clothes. She didn't know if she cut them herself, but they were more like the ones worn by workshop workers on Earth, but they couldn't hide her domineering figure. There are some scratches on the surface of the brown leather apron. I don’t know if they were scratched when cutting the glass.

But even so, the overalls and apron she wore on her body were actually beautiful, giving people a beautiful and sassy visual enjoyment.

"Mr. Ren, you are here too."

Ruan Tang tucked a strand of hair that fell in front of her eyes behind her ears, smiled and opened the door wide to let in the people outside.

"Miss Ruan is really amazing. In just two months, she made such exquisite glass and opened up the market."

Ren Pingsheng walked into the courtyard, looked at the neatly arranged furnishings in the courtyard, and praised them.

"I haven't thanked you yet, Mr. Ren."

Ruan Tang led Ren Pingsheng and others under the eaves, and asked Aunt Zhao to go into the house and bring out a few clean white porcelain cups and pour the tea leaves.

"Why thank you?"

Ren Pingsheng picked up the teacup and blew the foam on it.

This tea is much different from the ones at home. It smells mellow and fragrant, but it is slightly bitter when you drink it. After swallowing it, the sweetness is short and weak.

"If it weren't for Mr. Ren, my glass business wouldn't be so easy."

Ruan Tang said: “When I first started buying and selling glass, there were a few people with wrong attitudes, but I have never seen these people since.

I don’t know many people in Qingcheng Town, and among those I know who are capable of helping me, apart from Mr. Ren, I can’t think of anyone else. "

"Yes, Xiaowan said you are very careful. I think she is right."

Ren Pingsheng nodded.

In fact, what Ruan Tang said was conservative. There are at least thirty eyes and ears around this small courtyard, monitoring the place day and night. Even the neighbors, the food stalls she often goes to, Baiqiao Pavilion, several blacksmith shops, the businessmen, and Aunt Zhao are all without exception. They all received warnings from Ren Pingsheng.

To put it nicely, Ruan Tang is already living in the world of Truman that Ren Pingsheng created for her.

Putting down the teacup in his hand, Ren Pingsheng looked around at his surroundings.

The rooms in the courtyard have all been replaced with glass. They look no different from the glass on Earth, they are transparent and bright.

The slight flaw is that the glass is not that smooth, and occasionally there are bumps and bubbles caused by solidification, but these will not affect the lighting of the glass.

Near the eaves, a workbench the size of a table tennis table also caught Ren Pingsheng's attention. There were many tools on it that he couldn't name, but they looked familiar and professional.

Just on the ground next to the workbench is a large bundle of copper wire.

What is this used for?

"Um?"

When Ren Pingsheng's eyes turned to the workbench again, several parts on it suddenly attracted his attention.

The slide, spring, grip, magazine... When assembled together, wouldn't it just be a small biubiu!

Although the parts have not been polished and look very rough, it does not prevent this thing from being a handmade pistol.

His eyes were as wide as bells, and he couldn't help but glance at Ruan Tang. He saw her talking to Xiaowan with a flowery smile, her long eyelashes fluttering, and when she blinked, her big eyes looked gentle. Extremely!

"Ruan Tangqian looks thick-browed, gentle and gentle, but it turns out he's not honest either!"

Ren Pingsheng suppressed his inner evaluation for the time being.

He looked at a beautifully carved wall clock hanging on the wall under the eaves, with the hands pointing to three o'clock.

"Dang~dang~dang!"

Exactly three times in a row.

The wall clock is telling time!

This frightened Liu Wen, who was thinking about who the master was. He looked over and saw the clock hanging on the wall. He was relieved and asked: "Did you make this clock yourself?"

"right."

Ruan Tang nodded towards Liu Wen.

"This is Liu Wen, who is also from our Qixing Trading Company."

Ren Pingsheng introduced her.

"I'm Ruan Tang, hello Mr. Liu."

Ruan Tang nodded at him.

Liu Wen stood up and cupped his hands, confirmed again and asked: "Did you make the wall clock?"

"right!"

Ruan Tang nodded again.

This time, Liu Wen knew who the master was.

He has also studied clocks. What is particularly difficult to manufacture is the movement. There are countless gears and small parts in it. The production process alone is extremely troublesome. When assembled, they need to be fully engaged and balanced. , the tightness and tightness, the size and serration of any small part will not work.

A craftsman who can make clocks and watches can be called a master.

However, this expert turned out to be a beautiful woman, which was beyond his expectation. Moreover, even if she can make clocks, can she definitely make smokeless gunpowder?

Not necessarily? This is not the same type of thing.

"I heard from Xiaowan before that you have a pair of skillful hands. Looking at your dazzling little courtyard, it's really amazing!"

Ren Pingsheng spoke, interrupting her chat with Xiaowan.

"Sir, you are so complimentary."

"It's completely sincere, there's no way it would be ridiculous."

Ren Pingsheng waved his hand and gradually brought the topic to the purpose of his visit: "Miss Ruan, to be honest, we have come to ask for something."

"But it doesn't matter."

Ruan Tang's eyes lit up.

After she came to this world, she had received a lot of favors from Ren in her life. It was difficult to repay the favor except for her own life.

Moreover, the other party also helped him clear business obstacles, and the debt he owed became even greater.

In the past, Ruan Tang thought he was greedy for his body.

Now I find that the other party has other things to ask for. If she can solve the problem for the other party and return some favors, she will be able to relax a lot when facing the other party.

"Liu Wen, tell me."

Ren Pingsheng motioned to Liu Wen.

"Miss Ruan, that's it."

Liu Wen gestured with a spear in his hand, and while thinking about his boss's warning and considering the wording, he asked: "In our business, we want to increase the power of the firecrackers, but we found that the current gunpowder limits the power of the firecrackers. Power, we want to configure more powerful gunpowder, but we have never been able to find a suitable direction and have tried many times without success.

I wonder if Miss Ruan can give some ideas? "

Hearing this, Ruan Tang glanced at Ren Pingsheng in surprise.

I was surprised that a businessman on the other side was actually making guns and gunpowder.

I was also surprised that Qixing Trading Company didn't look that simple. No wonder it had such a big power.

I just don’t know who the firearms are being provided to.

"This Ren Shengsheng looks a bit dangerous. A gentleman does not stand under a dangerous wall. After repaying the favor, if there is a chance in the future, you still have to keep a distance from him, otherwise you don't know when you will be involved in danger. ”

Ruan Tang thought secretly.

She felt like she had traveled to another world. This world was still so dangerous, and now it was a time of war. She had to find a way to survive.

"What you are using now is black powder, and black powder itself does have some problems. The most important thing is that it is unstable. It is easy to explode when stored, and it is easy to explode the barrel when used. It has little power when used as a propellant, and it is easy to corrode the barrel of the gun... ··”

Ruan Tang looked up and saw Liu Wen's expectant and somewhat suspicious eyes.

She often saw this kind of look five years ago. It was a suspicion of her professional expectations because of her age.

"You guys come with me."

She stood up, led Ren Pingsheng and the other two people towards a room on the west side.

As soon as he entered the house, Ren Pingsheng was stunned.

The room was painted white, and the floor and tables were spotless.

And on the tables, crucibles, beakers, test tubes, alcohol lamps and other experimental equipment were all placed here openly.

I thought she was already very good at making glass, but I didn’t expect that she was even more awesome than I thought. She even made high-temperature resistant glass!

Moreover, Ruan Tang is unambiguous about these test instruments. Looking at them one by one, they all turn out to be high-quality products.

His hands-on ability is terrifying.
