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

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

Lao Zeng didn't know what he was busy with. Anyway, the Hualu Water Shop asked him to contact him now. He asked Lian Ice Cream Shop to contact him, but he was very busy.

"Oh? Okay, your highness, I'll get it now!" Lao Zeng replied quickly.

He did not have any time to say anything about Li Chengqian, so he did it immediately.

Li Chengqian called the shrimps, brought a pen and paper, and wrote: the ratios of saltpeter, sulfur and charcoal were controlled at about 75%, 10%, and 15%, respectively.

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

Lao Zeng brought what Li Chengqian wanted, and Li Chengqian immediately prepared black gunpowder according to the ratio in the formula.

He stirred all the three ingredients evenly, and looked like the black gunpowder he knew.

He divided a small handful, put it under the steps, and said to Lao Zeng: "Give me some incense."

"Good!" Lao Zeng ran away. After a while, he came back. He handed a long lit incense to Li Chengqian.

Li Chengqian touched the incense into the black gunpowder, and with a whisper, a ball of open fire began to rise, then it was extinguished, turning into a ball of white smoke and rising.

The burnt smell of gunpowder made Li Chengqian, who was not close to him, quickly took two steps back and suffocated the air in front of his nose with his hands, which made him feel a little better.

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

This should be gunpowder, he got it out.

He also wanted to continue experimenting with gunpowder. This gunpowder could not be used as a foreshadowing in the Tang Dynasty, and could only be used as a blasting object, so Li Chengqian wanted to try whether it could be used as a bomb.

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

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

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

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

The prince said that, and he immediately finished the things, and Li Chengqian couldn't help but feel satisfied with his status.

However, it is not good to be too big for this bamboo tube, so I poured half a bowl of gunpowder. Fortunately, I had a lot of it just now, otherwise it would not be enough now.

After loading it, 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. This fuse was made. He then stuffed a piece of the fuse into the mouth of the bamboo tube, and a bamboo tube bomb was completed.

Li Chengqian looked around and was very satisfied. He walked out of the attic and went outside. Xiao Xiami and Lao Zeng followed Li Chengqian curiously. After Li Chengqian put out the bamboo bomb, they had not walked away. He waved his hand and rushed in and said, "Let's go farther, go farther, this thing is very dangerous, leave quickly!"

Lao Zeng and Xiao Xiami were stunned, and then subconsciously wanted to execute Li Chengqian's words and leave here.

Lao Long said, "Your Highness, leave this dangerous thing to Lao Long!"

When Lao Zeng heard this, he regretted that such a good opportunity to show off his merits was snatched by a fool like Lao Long.

Li Chengqian waved his hand and said, "No, this fuse is long enough. You all leave me and hide behind the pillar. By the way, remember to leave a seat for me, so I can hide!"

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

But he would not miss this opportunity to make contributions!

Seeing that all the entry had been avoided, Li Chengqian turned around and looked at the half-meter-long fuse. It was a safe fuse. He carefully touched the fragrance to the end of the fuse. The quality of the fuse was quite good, and sparks flashed immediately.

Li Chengqian quickly ran away and hid behind the pillar.

At this time, the fuse had not been burned yet, Li Chengqian stuck his head out to see it. Seeing that the fuse finally burned to the bamboo tube, he shouted: "Everyone has been hiding for me, it's going to explode!"

Then he hurriedly hid in.

After only half a second, no explosion sounded, and I couldn't help but wonder, I carefully poked my head out to look at it.

Fortunately, Li Chengqian was not myopia and could see the situation of the bamboo-type bomb.

I saw that the fuse had burned out, and the ball of paper stuffed into the bamboo tube was burned up, but the paper was burned but the gunpowder inside was lit. This was really strange.

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

Li Chengqian grinned his teeth. At this time, he saw gunpowder flowers spewing out from under the bamboo tube. Li Chengqian became nervous and was about to hide in, but saw the bamboo tube wailing, and then a ball of white smoke came out from the bottom of the bamboo tube, and then the bamboo tube flew forward!

"Damn!" Li Chengqian cursed.

The bamboo tube flew towards Li Chengqian with a squirm, like a small rocket.

The little rocket flew over Li Chengqian in an instant, then hit the wall of the attic before stopping.

Li Chengqian looked at the intact bamboo tube and his butt was lying intact under the wall, and he couldn't help but pat his chest. Fortunately, if he flew here and exploded, Li Chengqian would not have become a victim in the history of gunpowder invention.

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

Li Chengqian felt that his credit was suspected, so he couldn't help but thrust his chest and walked towards the burned bamboo tube, wanting to pick it up. He immediately felt the hotness of the bamboo tube, put it down immediately, and then used another stick to get the bamboo tube up.

After carefully studying the bamboo tube, Li Chengqian found that the bamboo tube must be too raw and has a lot of moisture. It is another mature bamboo. The bamboo tube is too hard, so the gunpowder cannot be blown up even if it is fried.

"Get me some old bamboo tubes." Li Chengqian walked back with a stick and said to Lao Zeng.

After getting the Hsinchu tube, Li Chengqian carried out the process of filling in gunpowder.

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

However, Li Chengqian was facing the pool, but he was afraid that the bamboo tube would fly to him again. It didn't explode last time, so who knew if it would explode this time?

After putting it down, Li Chengqian handed the incense to Lao Long and said, "You come and light it, you 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.

After Li Chengqian looked carefully at the fuse, he started to burn the paper stuffed on the bamboo tube's butt. As soon as the paper burned almost, with a whisper, the bamboo tube's butt spurted out of fire and flew forward.

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

This is strange. I want to make a bomb, how did I make a rocket?
