Episode 842: [Fire]

……

When the eldest sister of the hippo saw Li Chengqian appear, she thought that she was in trouble, and hurriedly threw away the fire fold, which fell to the ground and touched the fuse, so the fuse was ignited and rang out sizzlingly.

Li Chengqian and the others were stunned.

This......

Although the small black ball is small, the explosion should not be too large. But a few people standing here will be injured by the explosion.

Sister Hippo also played just now, she can run after clicking, and she has played twice, which shows that it is really not very powerful. But this time, the fire fold fell in the middle of the fuse, and when it was time to run, half the distance was missing.

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

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

The eldest sister of the hippopotamus was caught, and she knew that it was not good, so she hurriedly ran along with Li Chengqian's strength.

Cheng Lao in the back, he will naturally run by himself.

But Li Chengqian didn't notice that Cheng Laoxiang didn't run, but kicked a big black pot next to the yard with his foot, emitting a metallic color.

It turned out that he was also wearing the same iron shoes as Li Chengqian on his feet.

The black cauldron was kicked by him, flew up, and then covered the bomb.

There was a thud on the ground, and you could see how good the weight of this black pot was.

Kiss! ――

A muffled sound came from the black cauldron.

Li Chengqian and the eldest sister of the hippo were stunned, turned back from the bunker, and saw that there was no explosion as expected. Instead, it was covered by a black cauldron.

Whew, fortunately nothing happened.

Even the black pot is there. It seems that the Gunpowder Bureau has mastered a lot of experience!

"Look at the good things you've done!" Li Chengqian scolded her.

But she lowered her head and pinched her clothes.

"Hey. It doesn't matter, in the gunpowder bureau, you can still make the princess have an accident! Cheng Lao said.

It seems that this old guy is watching the rockets and playing with them.

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

The eldest sister of the hippo raised her head and asked Li Chengqian, "But you said you took me out to play?" ”

Li Chengqian glared at her.

"If you want to play, you can play casually when you go to the test explosion field!" Cheng Lao said with an idea.

"Really?" Sister Hippo's eyes lit up and she looked at Cheng Lao Xiang excitedly. "Great, I'll go right away. Oh yes. I'll come back in a while. ”

With that, she ran away.

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

After a while, she came over. The clothes seem to have been sorted out and become neat.

She hooked her finger at Li Chengqian and said, "Big brother, come here." ”

Li Chengqian tilted his head and followed her.

When she got to the corner, Sister Hippo's hand stretched out from behind and said to Li Chengqian: "If you pull it bad, I'll take it on favorable terms." ”

After all that's said. Her hand stuffed the thing into Li Chengqian's arms.

After stuffing, he ran away.

Li Chengqian was stuffed by her in a daze, and he came back to his senses after she ran away. What does this do?

He looked down at what was in his clothes.

Pull it out, a small green band, and pull it out again. It's a grass-green piece of cloth.

Uh, what's this?

Pull it out again. It is warm in the hand, and it seems to be body temperature with it. But Li Chengqian knew that this was not his body temperature. That, then the body temperature is......

Li Chengqian glanced at the hippopotamus eldest sister who had already followed Cheng Laohuo, and the corners of his mouth twitched.

Unfold it, and sure enough, just as he thought, this is a belly pocket!

Wow, that's evil!

How can you put a belly pocket on him?

Wait, here are two straps that are broken.

That is, the strap is broken, so she can't wear it.

How did it break?

Li Chengqian remembered that when he caught the hippo sister and ran away just now, he grabbed her clothes, so that it was easy to pull the clothes inside. Tearing off the belly strap has become a normal thing.

Just now she went to untie this belly pocket and found that she couldn't wear it. I wanted to play again, and I couldn't take it with me, so I thought of the most secure big brother Li Chengqian, so I ignored the gender and stuffed it to him.

So Li Chengqian was left evil here!

Li Chengqian had cramps at the corners of his eyes, and finally reluctantly put the grass-green little girl's belly pocket into his arms.

Then I went in and gave a lecture. After the lecture, Li Chengqian asked them to divide the work according to their own strengths, such as warheads, thrusts, skins, and wires.

After some subdivision, Li Chengqian found that the outer skin was not something that these engineers could handle, and he still needed to find a blacksmith to do it.

As a result, the blacksmith, who had a very low status in the Gunpowder Bureau, suddenly became one of the small groups.

The other person who didn't get the job was the person who measured the distance and distance.

They will get gunpowder, where will calculate the distance to where, even if the distance is pulled out by the rope, but after the angle is measured, to calculate the distance of the flight, this seems to draw a lonely line, right?

Parabola?

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

Math knowledge in junior high school?

Then we need to find someone who can do math!

Li Chengqian had published a book on the knowledge of mathematics in elementary school before, and he sorted it out for Su Mi and published a part of it, and later Su Mi became pregnant, so he handed it over to his eldest sister who loves mathematics. The eldest sister is much more talented than Su Mi, so she found the students of Hongwenguan to do those maths together, and by trying first, she selected many people with mathematical talent to sort out Li Chengqian's mathematical knowledge.

So these children's books were successfully published.

Because the action was big, he was taken by Old Man Kong and took it to Hongwen Hall to teach.

Because some of the students have already learned these mathematical knowledge in depth, Old Man Kong is very open to a new kind of teaching, and the students teach the students.

This model has never been seen before. In the past, the emphasis was on the king being the king, and the minister being the minister. A teacher is a teacher, and a student is a student. There's no confusion going on.

Now this model is the first to be the teacher, very advanced, very open, so that the atmosphere in the Hongwen Museum suddenly lively.

Li Chengqian didn't think that because of his mathematical knowledge, it would be a side effect of the opening of the academy. Instead, I was thinking, mathematics has already been taught in the Royal Academy, so draw a few strong men from there and come here to do ranging. Wouldn't it be better?

After making up his mind, Li Chengqian put aside the ranging work first, and then went to draw strong men when he returned to the palace.

After the division of labor among the people below, let them go down and prepare.

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

Li Chengqian went around the powder magazine of this gunpowder bureau, and there were a lot of samples in it. It's still interesting. Li Chengqian walked around inside and came out.

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

Explosion testing ground?

pulled a person and took it to the test site.

Arrived at a clearing at the foot of the mountain. It is surrounded by high walls. The perimeter is guarded by a layer of soldiers, and it is impossible for anyone to enter.

As soon as Li Chengqian arrived here, he heard a booming sound. The sound of explosions is constant.

It's hilarious, not a monotonous explosion.

If it was all put by the hippopotamus sister. It's impossible, then there are other engineers in it who are interviewing and exploding.

Step inside. Sure enough, I saw a lot of engineers walking around, and some soldiers were carrying bombs over there, and when they arrived, they asked the engineers to test the explosion.

After sweeping the field, Li Chengqian finally found the hippopotamus sister in a corner, she and Cheng Laoxiang hid in a deep ditch, put a bomb in a pit not far in front, got a ignition device, and then hid in the deep ditch, pulled his hand, boom, the soil flew up, and covered the heads of the two people in the ditch, an old man and a young man, and the two laughed happily.

Lunatic!

Pretend not to see them.

Li Chengqian asked people to move a chair and sit there by himself, watching these two madmen go crazy there.

After the black balls in a large wooden box were blown up by them, Cheng Lao shouted loudly, and another soldier moved a box for them to play crazy.

This time it seems that the bomb is different.

When it was blown up, it didn't blow up the soil like before, but wrapped it up, and then drilled a hole in the ground.

After exploding a box, the hippo sister was familiar with it, and she shouted unceremoniously, asking people to bring new bombs over.

This is really fun, box after box, Li Chengqian's eyelids jumped, and he saw that the eldest sister of the hippo was not stingy with ammunition at all, and it was so cool.

Li Chengqian expressed shame on their wasteful behavior, so he stepped forward to stop it.

"Your Highness, this is a test bomb, it is all going to be exploded, Princess Huazhen is now worried about the ministers, which is also a good thing!" After Cheng Laoxiang finished speaking, he laughed first.

Cut, you know your excuse is funny!

Li Chengqian had no choice but to pretend that he didn't know them.

I won't do such a wasteful thing with you.

Li Chengqian walked around and walked around, and when he arrived in front of the powder magazine, there were really a lot of bombs in it, and said to the manager of the powder magazine: "These bombs? ”

The steward hurriedly said: "These bombs were all sent by the research department over there, I want to try them all to see if they can explode, and what the effect is, and now I am waiting for the people over there to explode, record them, and send them over there after the recording." ”

Oh, it seems that this powder keg, really for testing.

Li Chengqian pressed his hands behind his back and said: "Well, since that's the case, I'll send ten boxes, the boxes are different, come to me, and I'll also make some contributions to the Gunpowder Bureau!" ”

The steward was stunned for a moment, and hurriedly waved his hand and said, "How can this be, Your Highness is a body of ten thousand gold, how can you ......?"

After Li Chengqian rolled his eyes, the steward hurriedly closed his mouth, and then called soldiers to Li Chengqian and sent a few boxes of bombs.

I found a place far away from the hippopotamus, hid in a deep ditch, and then exploded the bombs of these tests with a bang.

I'm not playing like Sister Hippo, I'm testing, conducting a scientific test, understand?
