These are not simple stones, but some chemical raw materials, and in the materials brought by Richie, chemistry accounts for the largest proportion, because many scientific and technological developments are inseparable from chemistry.

As for chemistry, it was all an absolute secret, so Li Qi asked them to transport the stones to the former smelting area, which had become his laboratory since Rong and Ah Gu moved away.

"Great Chief, when I was in Baishan, I received news from Ku that they were coming back soon."

Chi suddenly whispered to Richie.

Hiro and Rumble have been outside all the time, and Li Qi has no way to send someone to call them back, so he can only wait until they have had enough waves and come back by himself.

"Looks like they're tired of being out there!" Li Qi shook his head with a wry smile, and said with a straight face: "But don't let them come here for the time being." As he spoke, he muttered a little, "Let them stay on the side of the White Mountain first, and be responsible for the mining of these stones, and the people who were originally stationed there will be sent back." ”

Many tribes have joined, because they have been fooled by rumbling them, if they are allowed to come here immediately, it may be a gang, although the current human beings are not very shrewd, but Li Qi is not willing to take this risk.

Chi looked back at the stone and said, "Great Chief, what is the use of these stones?" ”

"As I said earlier, these stones are so useful!" "Moreover, they are capable of producing a very powerful weapon. ”

A gleam immediately flashed in his red eyes, "A very powerful weapon? Could it be that the Great Chief wanted to polish the stones into weapons, but the stones were too brittle to be polished into weapons. ”

"I'm not referring to a different weapon than the one you know." Li Qi shook his head with a smile, and saw Chi looking at him curiously, so he said: "I can't tell you clearly for a while, and it's still in the research and development stage, so I have to keep it secret first, so I still need your help." ”

Chi nodded and didn't ask any more.

Li Qi asked again, "By the way, how is the factory there?" ”

Equator: "I went to the factory to take a look when I arrived, and the beasts and tanukimon were built much faster than us, and they were all made of stone and dirt. ”

As he spoke, he looked at the planning department, his expression a little complicated. They use big stones, they use wood, but they are far less fast than the tanuki beasts.

Li Qi smiled: "There is no need to envy them at this point, they can't produce wine." ”

....．

The next day, Li Qi and Chi went to their own laboratory, and as for Hanying, she was about to replenish her food. And the laboratory is actually a small cave, and inside it is a long table covered with silk, which is shabby.

"You're here to watch for me."

Li Qi instructed Chi, and then walked in.

When he came to the cave, he first took out a small rectangular box from his backpack, opened the combination lock, and opened the lid of the box, only to see that there was a blue film inside, and a thick pile of paper, and there were some droppers and other chemical gadgets on the lid. He first put the film on the lenses on his hood, then put on the hood and gloves. He's not a chemistry professional, and he has to be fully armed to do chemical experiments.

Arriving at the table, he poured various stone powders, which had been ground into powder, into the water, and then muttered the solution and dripped it onto a sheet of paper.

This paper is not ordinary paper, but a special kind of PH paper, which is a complete set of the film and the lenses on the hood.

After dropping into these ore solutions, if you don't have a head covering, you can't see anything from the paper, once you put on the head cover with a special film, you can see the chemical reaction between the solution and the paper, which will show a variety of colors on the paper, according to the color can identify the main components in the ore, and at the same time you can see what impurities are in it, and what is the proportion.

The paper has a lot of grids, and there are small grids inside the big grids, and you can see a very accurate ratio from this.

And then compare it from the information, you can know what the composition of these stones is, and what they can be used for, and the information is very clearly written.

This is a very rigid method, and it can even be said that it is specially used by fools, after all, Li Qi's chemical knowledge is limited, and he can occasionally pretend to be forced in the Northern Song Dynasty, but if you want to really develop science and technology, you must have professional knowledge reserves and accurate data.

In just a few moments, Li Qi had analyzed all the ingredients and recorded them.

Li Qi took off his hood, spit out a turbid breath, and muttered to himself: "It's really unreasonable, all the raw materials exceed the highest purity in the data, so you can't completely match it according to the data." ”

Thinking of this, he frowned, the scientist obviously customized a set of fool usage for him, but the change of materials made him have to use his brain.

Two more days passed.

"Do you want me to hold it for you?"

Chi saw that Li Qi was carrying a heavy basket with many small and large jars, so he asked, with a hint of curiosity in his eyes, Li Qi had never done such physical work before.

Li Qi shook his head and said, "No need! Try to stand on my left, it's all dangerous stuff. ”

He's heavily armed.

I glanced at the small jars, and saw that those small jars were very ordinary, but they were sealed with clay, and there was a slender line of dead leaves on the side, and there was curiosity in my eyes, what danger could this be.

Richie didn't explain either.

After walking for a while, the two of them came to a very remote Gobi, the Gobi here and the Gobi in the future are really two different things, it is not a whole piece, it is scattered, sometimes they don't take two steps on the grassland, they come to the Gobi, and the terrain is not the same as later.

Li Qi first observed the neighborhood before he said to the equator: "Let's start construction." ”

Chi immediately swung his hoe, and in a moment, he dug a small hole.

"It's almost so big!"

Li Qi took out a small jar with "1" written on it and put it in it, and said to the equator: "You stand farther away." ”

Chi took two steps back.

Li Qi wanted to cry without tears and said, "Is this far away?" Squat down behind the big rock. As he spoke, he pointed behind him.

Although Chi didn't understand it, he still squatted down behind the big stone according to his words, and the soldier just obeyed the order.

Richie lit the dead leaf line with a lighter, and then quickly stepped back a few steps.

Chi was surprised, I am so powerful, you squat so far, you are so weak, but you only take a few steps back. But I don't know that Li Qi is worried that the fragments of the explosion will hurt him, Li Qi is fully armed, of course there is no need to be afraid of these.

I waited for a while, but there was no reaction at all.

Chi, who was squatting in the back, felt very confused!

Li Qi walked over, poked the mud of the seal with a laughing file, carefully observed the inside of the jar, and muttered: "I know that the recipe on the information will become unreliable here!" ”

He took out a small notebook from his pocket and typed an X on top of the No. 1.

Then put it into the No. 2 small jar and light the dead leaf fuse.

After a while, smoke suddenly rose from the jar.

But that's about it!

Li Qi typed an X on the small notebook again, but it was relatively small, and he also made handwriting on the side.

Put in the number three again.

There was no movement at all.

Number Four!

Number Five!

The red gaze crouching behind gradually became dull, it was so boring, he didn't know what Li Qi was doing, but he was a very disciplined person, and he still squatted behind the big rock all the time.

Suddenly, I heard a pop sound.

Chi was stunned for a moment, looking for prestige, only to see a flash of fire rushing out, about a foot high, he blinked, and became confused again, this is a very powerful weapon? Even if he is powerful, he doesn't need to stand so far!

A flash of joy flashed in Li Qi's eyes, and he opened the small book again, looked at it, and said to himself: "The first five are all ordinary charcoal, but there is no reaction, and this sixth is added with dead leaf ash, which immediately reacts, it seems that this dead leaf ash is more suitable for today's sulfur and saltpeter, rather than charcoal." ”

But this is clearly a failed experiment.

The same is true of the seventh and eighth trumpets, except that the flame of the seventh is much lower, while the flame of the eighth has rushed out three feet high, and it is not black smoke, but pure white smoke, which looks like the fog, which is very different from the gunpowder of later generations.

Although they are all failures! But Li Qi was excited in his heart, because the height of the flame had already told him that if the research was successful, it might be very powerful, so he also retreated farther and farther.

Chi also gradually came back to his senses and watched intently, although he still didn't understand much, but at least there were fireworks to watch, so it wouldn't be so boring.

Rumble!

Suddenly, there was a loud noise on the ground, and the frightened and unprepared Chi directly sat on the ground, and the first few tests made him think that the powerful weapon that Li Qi was referring to was the small altar that would breathe fire, but he didn't expect it to explode, he had never seen an explosion, and he was not prepared at all, otherwise, with his psychological quality, he would not be scared to sit on the ground.

I saw a cloud of white smoke rising from the ground!

Li Qi excitedly took out a small notebook and put a tick on the ninth test.

"That's the powerful weapon you were talking about?"

This time, Chi couldn't help it, ran to Li Qi's side, and asked in surprise.

Li Qi smiled: "Of course not, it's just the material used to produce powerful weapons." ”

As he spoke, he came to the pit, waved his hand, cleared the white smoke that had faded, and looked into the pit, but saw that the white smoke was still rising from the soil.

"What about the jar?" Chi said curiously.

Li Qi raised his hand and pointed casually: "It's everywhere." As he spoke, he laughed himself, and said in his heart, sure enough, this high-purity material with dead leaf ash to produce gunpowder is not inferior to the power of primary chemical gunpowder.
