"Lao Zeng, go and get me some saltpeter, charcoal, and sulfur."

As soon as Li Chengqian entered the East Palace, he shouted to Lao Zeng.

Lao Zeng didn't know what he was busy with, anyway, now the flower water shop asked him to contact, and asked the lotus ice cream shop to contact him, but he was very busy.

"O? Okay, Your Highness, I'll go get it! Lao Zeng hurriedly responded.

He didn't hesitate to say anything about Li Chengqian, and he did it immediately.

Li Chengqian beckoned a small shrimp, brought a pen and paper, and wrote: The proportions of saltpeter, sulfur, and charcoal are controlled at about 75 percent, 10 percent, and 15 percent respectively.

This recipe can be written as long as you have been in junior high school.

Lao Zeng brought what Li Chengqian wanted, and Li Chengqian immediately prepared black powder according to the proportion on the formula.

He mixed all the three ingredients, and looked at the black powder he knew.

He took out a handful, put it under the steps, and then said to Lao Zeng, "Give me some incense." ”

"Good Ratcha!" Lao Zeng ran away, and when he came back after a while, he handed a long lit incense stick to Li Chengqian.

Li Chengqian touched the incense into the black powder, and with a snort, an open flame ignited, then extinguished, turned into a cloud of white smoke, and rose.

The smell of gunpowder made Li Chengqian, who was not close, hurriedly take two steps back, and fanned the air in front of his nose with his hand, which made him feel better.

Although he was choked by gunpowder, Li Chengqian was happy.

This was supposed to be gunpowder, and he got it out.

He also wanted to continue experimenting with gunpowder. This gunpowder could not be made into a gun in the Tang Dynasty to foreshadow, but could only be used as explosives, so Li Chengqian wanted to try to see if it could be used as a bomb.

"Go get me a bamboo tube!" Li Chengqian said excitedly.

Lao Zeng, the old dog's leg, immediately ran to get it.

Li Chengqian took the gunpowder in the bamboo tube that Lao Zeng brought.

The diameter of this bamboo tube is five centimeters, and it is the middle part of a mature bamboo, and the bamboo has a lot of moisture, and it seems that the bamboo has just been cut and cut.

As soon as the prince's words were made, Li Chengqian couldn't help but be satisfied with his status.

However, this bamboo tube is too big and not very good, so half a bowl of gunpowder was poured, but fortunately it was more than just now, otherwise it would not be enough now.

After it was loaded, Li Chengqian took out a ball of paper, the paper was very soft, Li Chengqian rolled the paper into a line, and then kneaded gunpowder on it, so that a fuse became a fuse. He took another mass and stuffed part of the fuse into the mouth of the bamboo tube, so that the bamboo tube bomb was completed.

Li Chengqian looked left and right, very satisfied, he walked out of the attic, and outside, Xiao Xiami and Lao Zeng were curious to follow Li Chengqian, after Li Chengqian put the bamboo tube bomb, a few of them didn't go away, he waved his hand, rushed in and said: "Go farther, go farther, this thing is very dangerous, leave quickly!" ”

Lao Zeng and Xiao Xiami were stunned for a moment, and then subconsciously wanted to carry out Li Chengqian's words and leave here.

The old dragon said: "Your Highness, leave this dangerous thing to the old dragon!" ”

When Lao Zeng heard this, he regretted that he had such a good opportunity to show his merits, but he was robbed by such a fool as Lao Long.

Li Chengqian waved his hand and said: "No, this fuse is long enough, you all leave for me, and then hide behind the pillar, by the way, remember to leave a seat for me, I'm so hiding!" ”

"Okay, Your Highness, I'll take a seat for you!" Lao Zeng said.

He didn't miss this opportunity to build credit!

Li Chengqian saw that all the entrances were hidden, so he turned around and looked at the fuse half a meter long, which was really a safe fuse, and he carefully touched the incense to the end of the fuse, and the quality of the fuse was quite good, and sparks flashed immediately.

Li Chengqian hurriedly fled and hid behind the pillar.

At this time, the fuse had not yet burned out, Li Chengqian poked his head out to look, saw that the fuse had finally burned to the bamboo tube, and shouted: "Everyone has hid for me, it's going to explode!" ”

Then he hurriedly hid inside.

It was only half a second later, and I didn't hear an explosion a second later, so I couldn't help but poke my head out carefully to look.

Fortunately, Li Chengqian is not short-sighted and can see the situation of bamboo tube bombs.

I saw that the fuse had been burned out, and the ball of paper plugged in the bamboo tube was burned, and the paper was burned but the gunpowder inside was not lit, which was really strange.

Could it be that the paper was stuffed too tightly just now?

Li Chengqian bared his teeth, and then saw that there were gunpowder flowers spewing out under the bamboo tube, Li Chengqian became nervous, and was about to hide in, but he saw the bamboo tube snort, and then saw a cloud of white smoke coming out of the bottom of the bamboo tube, and then the bamboo tube flew forward!

"Damn!" Li Chengqian scolded.

The bamboo tube snorted and flew towards Li Chengqian's side, like a small rocket.

The small rocket flew past Li Chengqian's side in an instant, and then hit the wall of the attic before stopping.

Li Chengqian looked at the intact bamboo tube just that his buttocks were blackened, lying under the wall intact, and couldn't help patting his chest, fortunately, if he flew here and exploded, then Li Chengqian would not have become a victim in the history of gunpowder invention now.

Lao Zeng, Lao Long, and Xiao Xiami looked at Li Chengqian very strangely.

Li Chengqian felt that his credibility was doubted, so he couldn't help but puff up his chest and walked towards the bamboo tube that had been burned.

After carefully studying the bamboo tube, Li Chengqian found that the bamboo tube must be too raw, with a lot of moisture, and it is a mature bamboo, so the bamboo tube is too hard, so the gunpowder can't be exploded.

"Get me some old bamboo tubes." Li Chengqian put a stick on the bamboo tube, walked back, and said to Lao Zeng.

After getting the new bamboo tube, Li Chengqian carried out the process of filling gunpowder again.

After everything was done, Li Chengqian put the bamboo tube back in its original place and prepared for a new ignition ceremony.

However, the direction in which Li Chengqian put it, but facing the pool, he was afraid that the bamboo tube flew to him again, and it didn't blow up last time, who knows if it will blow up this time.

After putting it away, Li Chengqian handed the incense to Lao Long and said, "You come and light, after you light it, you will run back, you must run faster." ”

The old dragon nodded.

After Li Chengqian hid, Lao Long lit the fuse and ran back in a few steps.

Li Chengqian watched carefully as the fuse was burned, and then he burned the paper stuffed in the butt of the bamboo tube, and as soon as the paper burned almost to the ground, the butt of the bamboo tube spewed out fire and flew forward.

Well, this is obviously a small rocket, where is the bomb!

It's weird, I want to make a bomb, how do I make a rocket?

It doesn't make sense?
