The rocket launch is like this:

This is the city on the river, and there are rockets on the other side of the river. To shoot the rocket onto the city, the width of the river is the angle from the rocket, which will affect the distance of the rocket. The distance is as long as it is, it requires sufficient amount of gunpowder for thrust.

Therefore, someone needs to calculate the distance and angle here to calculate the distance

The amount of gunpowder burns and how many ways to fly will be studied by the gunpowder engineer.

The distance determines the amount of gunpowder, but the rocket is made, and the amount of gunpowder inside has been fixed. When it encounters a distance, it cannot be fired, and when it encounters a close distance, it is wasted gunpowder, so Li Chengqian thought of a way to classify the rocket.

This classification is divided into the amount of gunpowder that makes the thrust

For example, the distance is one hundred meters, as the first level, three hundred meters, three hundred meters, three levels, eight hundred meters, four levels, and kilometers are level five. It is not known how many distances the actual war will take is appropriate, so I will divide it like this for the time being.

If the warhead and thrust gunpowder are integrated, then many rockets must be made according to these classifications.

In this way, in actual combat, all the graded rockets have to be brought with me, but I'm afraid it's very heavy

So Li Chengqian thought of dividing rockets into thrust gunpowder, warhead, and skin.

When it comes to the battle, you can assemble it temporarily. The thrust gunpowder needs to be assembled at any distance. Of course, the warhead can also be enriched in the future. Should you need a physical bomb, a blasting bomb, or a scattered flower bomb? If you can get a nuclear bomb in the future, then you can also install it by the way. Hahahaha

Li Chengqian stood on the top and followed the people below to speak happily. The more he talked, the smoother he was in his brain, the better he performed. He said everything he thought of in his mind. Finally, he talked about the principle of what kind of airflow that the rocket needs to be made out of the outer skin. The flying wings fly in the air.

Just as the airflow is used well, you can continue to fly forward after the gunpowder is burned, this is a saving moment, suddenly, the ground trembles, and then an explosion sounds

Li Chengqian quickly blocked the ashes flying everywhere with his hands

"This is..." Li Chengqian's face showed a confused look. He suddenly thought of something and asked, "Is this an explosion?"

It is normal for an explosion in the Gunpowder Bureau. I heard that no less than a hundred projects have died here, Amen

Li Chengqian thought that he should go and rescue him now and reduce the losses to the minimum

"This... doesn't seem like it exploded in the laboratory?" An engineer stood up and said suspiciously.

As soon as this was said, everyone else said that they were all people who were used to explosions in the gunpowder bureau. They had already practiced listening to sounds and earth movements and felt that there was an explosion in the laboratory that occurred in the laboratory.

Now so many people deny that it is not a research explosion, what's going on?

Everyone was about to come to a conclusion, suddenly another explosion sounded and the ground was shocked again

This is another explosion

Li Chengqian tightened his chrysanthemum and asked, "Is it possible that there was a series of explosions in the gunpowder depot?"

When everyone heard this, their faces turned pale, but they were all people with common sense and experience. They shook their heads quickly and said, "Your Highness, the gunpowder depot cannot explode at this time. It's not like this that explosion is not just a small fear..."

He turned his head and looked at the others, and said strangely: "Yes, in the compound."

"Where?" Li Chengqian looked at him blankly

The engineer explained: "It's the clearing in the middle when we came in."

The Gunpowder Bureau is like a courtyard with a patio in the middle and a house around it. What the engineer said is that the patio in the middle is determined that there will be no bomb explosion.

So everyone guessed it, artificial

"Quick, go out and have a look," a engineer called out, and ran outside

Then the others ran out too

Lao Long stood in front of Li Chengqian

"Let's go and see." Li Chengqian also wanted to see what happened.

Lao Long obviously didn't want to do it, but this is the Gunpowder Bureau, and no matter how dangerous it is, it is not much dangerous. So he loyally protected Li Chengqian out.

Li Chengqian went outside and saw that there were already three floors in the yard, one of which was engineer and one of which was soldiers. The middle seemed to be the culprit this time, but they all stood still and did not take down the culprit in the middle, and were still watching the show.

Just as Li Chengqian was thinking about killing himself, the voice of the hippo sister came from inside:

"Hey, what are you doing here? I'm going to snatch a cannon. Get out of here. You don't run away, but you can't block my way."

How arrogant this is said

Suddenly, the crowd became panicked and ran around

At this time, Li Chengqian knew that the culprit in the middle was the hippo. She said that she set off firecrackers, which showed that the explosion just now was made. Thinking of this, Li Chengqian had a cold sweat on his forehead. She was so naughty, could she use bombs as firecrackers?

"Hahahahahahaha..." A ecstatic laughed.

Then Cheng Laohuo appeared

At this time, everyone on the field had almost run away, and Li Chengqian also saw what was going on in the middle

Sister Hippo is bent over, with a small black ball in the middle, and the small black bead has a long fuse

There are black marks after the explosion on the ground, which she just exploded

She is now making an explosive, holding a fire stick in her hand, with a lengthened handle, and cannons can be fired at any time

In this way, it would be strange if she didn't scare to death by her,

Moreover, her identity is Princess Huazhen. Even if she is not her biological child, she has the title of a princess. Can she have an accident in the Gunpowder Bureau? So the people in the Gunpowder Bureau are very smart and run away.

At this time, the devil Cheng Lao Huo came out, so he should be able to stop this devil princess?

Not only the engineers and soldiers were thinking, but Li Chengqian was thinking too

"Princess Huazhen is really a surname. This cannon is launched well, and I'm itchy when I see it." Old Man Cheng said with a haha

As soon as Li Chengqian said this, the engineers and soldiers around him also made the head feel a little unreliable.

"Ah, OK," Sister Hippo responded happily.

Li Chengqian couldn't bear to see it anymore. Although he wanted to pretend not to know her, he knew that the prince and the princess were in the same group, so he couldn't let her be embarrassed anymore.

"Okay, you can't fire a fire here casually." Li Chengqian stood out and shouted

Sister Hippo is still a little afraid of Li Chengqian. When she heard this, she quickly put down the things in her hand.

The fire break fell on the fuse

Several people couldn't help but be stunned
Chapter completed!
