"What are these?"

Xiao Wan asked, looking at the bottles and jars.

"It's some experimental supplies, and if you want to make better gunpowder, you need these things."

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

There was some black granular stuff in it, and she pursed her lips and looked at Ren Pingsheng with her eyes.

Aware of the dangers of the outside world, she has a strong sense of crisis about her own safety.

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

These days, I took the time to get smokeless gunpowder out, and I also rubbed a pistol for myself.

I plan to pull out some more pistols and pop them out, so that I can at least have some self-protection in the face of danger.

Now, Ren Pingsheng found her here because of the gunpowder matter, and she could have pretended not to understand and pushed it all away.

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

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

I don't know, it's not a good thing for me, I don't know if it's a reward or a captivity.

It was an adventure for her.

"Is this gunpowder?"

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

He was a little excited.

"Yes."

Ruan Tang nodded: "This is smokeless gunpowder, compared to black powder, if it is used for bullet propellant charge, it can bring greater power."

Usually store, transport, and use, because the ignition point is higher, it is also safer. ”

"Can I take a look?"

Liu Wen asked.

Nguyen Sugar pushed the beaker over.

Liu Wen reached out and pinched it out, put it in the palm of his hand and looked at it carefully.

But how could this thing be seen just by looking at it, and he asked expectantly, "Can you teach me?" ”

He had already admitted that the woman in front of him was really a tall person.

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, take out your own tools, starting from raw materials, to refining nitric acid, sulfuric acid, to making nitrocellulose, from ether, ethanol, diphenylamine refining, until finally synthesized into a dried gum section.

The whole complete step was taken through by Liu Wen, which deeply shocked Liu Wen.

For the first time, he knew the true effect of experiments, and how the collision of various substances produced so many changes.

Even though he studied with the books given by the owner for several months and watched the videos on the tablet for more than two months, this was the first time he felt the charm of science so intuitively!

He was extremely sure that the woman in front of him had incomparably more erudite experience and knowledge than he had!

At this moment, he had the idea of "dying at the end of the day", and he didn't even want to go back to 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 learn this magical and charming knowledge with this erudite woman!

He recorded it carefully, recorded the whole process deeply in his heart, memorized every important step repeatedly, and corroborated it with what he had learned from books and videos before.

Especially many gambling points that stuck them before, the synthesis of those basic materials, after listening to it at this moment, it suddenly dawned on me and knew which direction to look for the answer.

By the time everyone walked out of the lab, it was already dark outside.

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

"By the way, Miss Ruan, this is a new type of firecracker we designed, which is more convenient than assembling the army's firecracker, but it is often jammed and not very easy to use."

Finally caught the master, Liu Wen took out a piece of paper from his chest pocket.

Above it is a charcoal drawing with the appearance and size of the firearm.

Ruan Tang took a look at it and found that it looked like a classic old gun on the earth - 98K.

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

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

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

According to this design drawing, the scientific and technological level and productivity of this era are much more advanced than the Ming Dynasty period that I imagined.

"What about bullets? What does it look like? ”

She asked.

"Miss Ruan, look."

Liu Wen deliberately brought a few bullets, and he just took them out at this time.

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

Judging from these guns and bullets, the technological level of this world, at least the level of firearms, may already have the level of the pre-World War I.

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

Ruan Tang thought as he took out a charcoal pen, casually changed a few parameters on the drawing, and slightly changed the structure of the gun body.

In the end, I drew a new one on the drawing, and drew the design drawings and parameters separately from the accessories that I had modified.

Finally, I drew an object with springs, hinges, and so on.

"In this way, the problem is solved, under such a gun body structure, although some of the performance of the gun will be sacrificed, but at least the bullet can be fired out in such a roll, even if there is a slight difference in the caliber of the bullet, there is no problem.

In addition, this last thing can help workers roll copper bullet shells by hand, and they can be rolled out without much effort, and the yield is higher than the way your bullet is made. ”

Ruan Tang returned the drawings to Liu Wen.

Liu Wen, who took over the drawings, also went from not believing in Ruan Tang at the beginning, to being suspicious of the generals later, and now he has been completely impressed by Ruan Tang's ability.

"Miss Ruan really let me live up to my expectations, if it is useful to Ren, even if I talk to Xiaowan.

In addition, Miss Ruan's set of things in the West Chamber, I don't know how much it costs, can it be sold to us as a set? ”

Ren Pingsheng asked.

"I'll give you ····· if you need it"

"No, I'm not short of silver, why don't I make a price of 50 taels, how about I call Xiaowan to come over and get it in three days?"

Ren Pingsheng said directly.

"Okay."

Ruan Tang was no longer polite to Ren Pingsheng.

"In this way, it won't be early, so we won't disturb Miss Ruan's rest."

Ren Pingsheng took the opportunity to say goodbye.

After sending Ren Pingsheng and the three of them away, Ruan Tang returned to the eaves with a heavy face.

"He must be investigating me! How else would I 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 had purchased from the outside world, so he came to visit this time.

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

"Moreover, who is this Ren Pingsheng? Just a businessman's words, what do you do with these guns and gunpowder? Is it the court, or the white gloves of some warlord's power? Or is it something else? ”
