Chapter 842: [Fire a Fire]

...

When Sister Hippo saw Li Chengqian appear, she thought she had caused trouble and quickly threw away the fire note. The fire note fell to the ground and hit the fuse, so the fuse was ignited and rang out loud.

Li Chengqian and others were stunned.

this……

Although it is estimated that the explosion volume of this little black ball should not be too large. 5. How many people are standing here, they will be injured by the explosion?

Sister Hippo has played with it just now, and she can lit it and ran away. After playing it twice, it means it is really not very powerful. But this time the fire break fell into the middle of the fuse, and if you want to run, you will lose half the distance.

Anyway, at this time, Li Chengqian and Hippo were in danger.

"Let's go!" Li Chengqian shouted, grabbed the hippo's clothes with both hands, and pulled her to the cover.

Sister Hippo was caught and knew it was not good, so she hurriedly followed Li Chengqian's strength.

The old man Cheng behind him will naturally run away by himself.

But Li Chengqian did not notice that Cheng Laohuo did not run away, but kicked a big black pot next to the yard, making a metallic look.

It turned out that he was wearing iron shoes like Li Chengqian on his feet.

He kicked the pot and flew up, then covered the bomb.

A thud from the ground shows how good the weight of the black pot is.

Bo!

A muffled sound came from the black pot.

Li Chengqian and Hippo were stunned and turned around from the cover, seeing that there was no explosion as expected. Instead, they were covered by the black pot.

Huh, fortunately no trouble happened.

Even the bad guys are there. It seems that the Gunpowder Bureau has mastered a lot of experience!

"Look at your good things!" Li Chengqian cursed at her.

But she lowered her head and pinched her clothes.

"Hey. It's okay, in the gunpowder bureau, can something happen to the princess!" said Mr. Cheng.

It seems that this old guy has been watching rockets and has become more fun.

"That's not OK, this bomb is too dangerous." Li Chengqian waved his hand.

Sister Hippo raised her head and asked Li Chengqian back, "But you said you took me out to play?"

Li Chengqian glared at her.

"You can play if you want to play, just go and try the explosive scene and play it casually!" Cheng Lao Huo said with an idea.

"Really?" Sister Hippo's eyes lit up and she looked at Old Man Cheng excitedly. "That's great, I'll go right away. Oh by the way. I'll go and come over again later."

After saying that, she ran away.

I don't know what she's going to do.

After a while, she came over. The clothes seemed to have been tidied up and became neat.

She hooked her finger at Li Chengqian and said, "Brother come here."

Li Chengqian tilted his head and followed her.

When he arrived at the corner, Sister Hippo reached out from behind and said to Li Chengqian: "You're broken, I'll take it if you have the favorable conditions."

After saying that, her hand stuffed the thing into Li Chengqian's clothes.

After stuffing, he ran away.

Li Chengqian let her hold her in a daze. Only after she ran away did he come to his senses. What is this to do?

He looked down at what was in his clothes.

Pull it out, a small green belt, and then pull it out. It is a piece of grass-green cloth.

Uh, what is this?

Pull it out again. Hold it in your hand warm, and it seems to be your body temperature. But Li Chengqian knew that this was not his body temperature. Then, then the body temperature was...

Li Chengqian looked at Sister Hippo who had already walked away with Old Man Cheng, and his mouth twitched.

When I expanded it, I found that it was a bellyband as he thought!

Oh, it's so evil!

How could I stuff a bellyband on him?

Wait, there are two straps that are broken.

In other words, the strap was broken, so she couldn't wear it anymore.

How did it break?

Li Chengqian remembered that when he caught the hippo and ran away, he grabbed her clothes. In this way, it would be easy to pull the clothes inside. It would become normal for him to break the bellyband strap.

Just now, she went to untickle the bellyband and found that she could not wear it anymore. She wanted to play again and could not carry it with her. So she thought of Brother Li Chengqian, who felt the most secure, so she ignored her gender and stuffed it to him.

So Li Chengqian is left to be evil here!

Li Chengqian's eyes twitched, and finally he had no choice but to put the grass-green little girl's bellyband into his arms.

Then he went in and continued the lecture. After the class, Li Chengqian asked them to group. If they had their own strengths, they would divide the labor, warhead, thrust, outer skin, and wires according to their own strengths.

After some subdivision of the work, Li Chengqian discovered that the skin was not something these engineers could do, and they still needed to find a blacksmith to do it.

So, the blacksmith, who had a very low status in the Gunpowder Bureau, suddenly became one of the group parts.

Another person who did not get a division of labor was the distance and distance.

They will get gunpowder and calculate where they can go. Even if the distance is pulled out by the rope, after the angle is measured, they have to calculate the flight distance. It seems that they need to draw a single line?

parabola?

Li Chengqian touched his head himself, and forgot all the knowledge in junior high school.

Mathematics knowledge in junior high school?

Then you need to find someone who knows how to do math!

Li Chengqian had published books on elementary school mathematics knowledge before, and compiled them for Su Mi and published some of them. Later, when Su Mi became pregnant, she gave them to the eldest girl who loved mathematics. The eldest girl was much more fashionable than Su Mi, so she found students from Hongwenguan to do the mathematics together. By trying first, she then selected many people with mathematical talent to sort out Li Chengqian's mathematical knowledge.

So these books were published successfully.

Because he was so active, Old Man Kong fell in love with him and took him to Hongwenguan for teaching.

Because some of the students have already learned these mathematical knowledge deeply, Old Man Kong has conducted a new teaching openly, and students will teach students.

This model has never been done before. In the past, it was emphasized that the king was the king, the minister was the minister. The teacher was the teacher, and the students were the students. It should not be confused.

Now this model is that the first one is to teach, which is very advanced and open, making the atmosphere in Hongwenguan liven up suddenly.

Li Chengqian thought this way not because he felt that his mathematical knowledge caused the side effects of the college's openness. Instead, he thought that mathematics has been taught in the Royal Academy, so he would draw a few strong men from there and come here to do distance measurement. Wouldn't that be fine?

After making up this idea, Li Chengqian put the distance measurement work aside first, and then went to the palace to get the strong men. Now, just group them like this first.

After the division of labor was completed, the people below asked them to go down and prepare.

After Li Chengqian distributed all the drawings to them, he had nothing to do and went around.

Li Chengqian went around the gunpowder bank of the Gunpowder Bureau and put a lot of samples in it. It was still interesting. Li Chengqian walked around it and then came out.

Li Chengqian touched his chin, where did this hippo sister go?

Test explosion?

He pulled someone and took them to the test blast.

When I arrived at a clearing space at the foot of the mountain, there were high walls around it and a layer of soldiers guarding the outside. It was impossible for anyone to come in.

As soon as Li Chengqian arrived here, he heard a booming sound. The explosions kept coming.

This is very lively, not a monotonous explosion.

If it was all put by Sister Hippo, it would be impossible, then there were other engineers inside to try it out.

When I walked inside, I saw many engineers walking around. Some soldiers were carrying bombs there. When I came to the point of pointing the engineers to try the explosion.

After sweeping the field, Li Chengqian finally found Sister Hippo in a corner. She and Old Huo Cheng hid in a deep ditch. A pit not far away from front placed a bomb, made a ignition device, and then hid in the deep ditch. With his hands pulled and banged, the soil flew up and covered the heads of the two old and young in the ditch. The two actually laughed happily.

madman!

Pretend not to see them.

Li Chengqian asked someone to move a chair and sit there by himself, watching the two lunatics playing crazy there.

After they exploded a large wooden box of black balls, Cheng Laohuo shouted loudly, and another soldier brought them a box to make them play crazy.

This time it seems that the bomb is different.

When it exploded, it did not blow up the soil like before, but wrapped it up and then drilled a hole on the ground.
