Behind me is the earth

"what are these?"

Xiaowan asked, looking at these bottles and jars.

"They are some experimental supplies. If you want to make better gunpowder, you need to use these things."

Ruan Tang said, bending down and taking out a large beaker from a cabinet.

There were some black granular things inside. She pursed her lips and looked at Ren Pingsheng.

Knowing the dangers in the outside world, she has a strong sense of crisis for her own safety.

In addition, the clouds of war began to brew in the sky, and she felt even more insecure when she was alone in this world.

These days, I took the time to get smokeless gunpowder and rub my hands into a pistol.

I plan to pick out some more pistols and pop them out, so that I can at least have some ability to protect myself when facing danger.

Now, Ren Pingsheng came to her because of the gunpowder matter. She could have pretended not to understand and dismissed it completely.

But the other party helped her more than once, and she is not a person who does not repay kindness.

But she didn't know whether giving these dangerous things to the man in front of her was a good thing for the world.

I don’t know if this is a good thing for me. I don’t know if I will get rewards or imprisonment.

This is an adventure for her.

"Is this gunpowder?"

Liu Wen couldn't hold his breath. Looking at the black particles in the glass, his intuition told him that this was probably the smokeless gunpowder he had dreamed of!

He was a little excited.

"right."

Ruan Tang nodded: "This is smokeless gunpowder. Compared with black powder, it can bring greater power when used as a bullet propellant.

It is safer for daily storage, transportation and use because the ignition point is higher. "

"May I take a look at it?"

Liu Wenxun asked.

Ruan Tang pushed the beaker over.

Liu Wen reached out and pinched a handful, put it in his hand and looked at it carefully.

But how could he tell this thing just by looking at it? He asked expectantly: "Can you teach me?"

He has admitted that the woman in front of him is really an expert.

Since Ruan Tang looked at Ren Pingsheng's face and had already taken out the smokeless gunpowder, he naturally did not hesitate to teach these things to Liu Wen.

Immediately, he took out his own tools, starting from raw materials, refining nitric acid and sulfuric acid, making nitrocellulose, refining ether, ethanol, and diphenylamine, and finally synthesizing it into a dried colloid slice.

Liu Wen was taken through the entire complete steps, which deeply shocked Liu Wen.

For the first time, he knew the real function of the experiment, and knew that the collision of various substances could produce so many changes.

Even though he has been studying with the books given by his boss for several months and watching videos on his tablet for more than two months, this is the first time that he has felt the charm of science so intuitively!

He was extremely certain that the woman in front of him had extremely erudite experience and knowledge that far exceeded him!

At this moment, he had the idea of ​​"I will die if I hear the truth in the morning." He didn't even want to go back and be the head of the engineering department. He just wanted to be an apprentice in this small courtyard that looked very inconspicuous from the outside, and work with this Learned women should learn this magical and charming knowledge!

He recorded it carefully, recording the whole process deeply in his mind, memorizing every important step over and over again, and corroborating it with what he had learned from books and videos before. There were many areas that were difficult to solve before. suddenly see the light.

Especially many of the gambling points that had stuck them before, the synthesis of those basic materials, now after listening to it, they suddenly understood and knew which direction to look for the answer.

When everyone walked out of the laboratory, it was almost dark outside.

At this time, Liu Wen realized that his hands and feet were numb.

"By the way, Miss Ruan, this is a new type of firecracker we designed. It is more convenient than the firecrackers currently assembled in the army, but it often gets stuck and is not very easy to use."

After finally catching the master, Liu Wen took out a piece of paper from his chest pocket.

On it is a charcoal drawing, marking the appearance and size of the firearm.

Ruan Tang took a quick look and found that it looked like a classic old gun on Earth - 98K.

"The technology in this world is higher than I imagined."

Looking at this drawing, she couldn't help but think about it.

A gun reflects all aspects. At least Ruan Tang can see the basic materials, basic knowledge, design level, forging process, productivity and so on.

According to what this design drawing reflects, the technological level and productivity of this era are much more advanced than what I imagined during the Ming Dynasty.

"Where are the bullets? What do they look like?"

she asked.

"Miss Ruan, look."

Liu Wen specially brought a few bullets and took them out at this time.

Ruan Tang looked at the bullets Liu Wen gave him and found that even the bullets were very similar to rifle bullets on earth.

Judging from these firearms and bullets, the technological level of this world, at least the level of firearms, may already be at the level of the early World War I.

Then, it seems unreliable to rely on a small pistol to protect your own safety.

While Ruan Tang was thinking, he took out a charcoal pencil, casually changed a few parameters on the drawing, and slightly changed the structure of the gun body.

Finally, I drew a new one on the drawing, and drew the design drawings and parameters of the modified accessories separately.

Finally, I drew another object with springs, hinges and the like.

"This solves the problem. With such a gun body structure, although some firearm performance will be sacrificed, at least it can shoot bullets rolled in this way. Even if the caliber of the bullets is slightly different, there will be no problem.

In addition, this last thing can help workers roll copper bullet casings by hand. It can be rolled out without much effort, and the yield is higher than the way you make this bullet. "

Ruan Tang returned the drawings to Liu Wen.

Liu Wen, who took over the drawings, went from not believing in Ruan Tang at the beginning to being doubtful, and now he is completely impressed by Ruan Tang's abilities.

"Miss Ruan has indeed lived up to my expectations. If you can be of any use to Ren, just tell Xiaowan.

In addition, I don’t know how much the set of things in the west wing of Miss Ruan’s house cost. Can you sell us a set? "

Ren Pingsheng asked.

"I'll send it to you if necessary..."

"No, I'm not short of silver. Why don't we just price it at 50 taels? How about I ask Xiaowan to come over and get it in three days?"

Ren Pingsheng said directly.

"good."

Ruan Tang was no longer polite to Ren Pingsheng.

"In this case, it's getting late, so we won't disturb Miss Ruan's rest."

Ren Pingsheng took the opportunity to say goodbye.

After sending Ren Pingsheng and the others away, Ruan Tang returned to the roof with a heavy expression.

"He must be investigating me! Otherwise, how would he know that I made smokeless gunpowder?"

She thought silently.

Ruan Tang felt that the other party must have known that he was making gunpowder through the materials he purchased from the outside world, so he paid this visit.

After all, the other party can also make black powder, so it is not difficult to infer that he is making gunpowder from the raw materials he purchased.

"Furthermore, who is this Ren Pingsheng? If he is just a businessman, what is he doing studying these guns and gunpowder? Is he the white glove of the imperial court or a warlord? Or does he have another identity?"
