……

They were stunned for a moment, then smiled awkwardly.

But when Li Chengqian was angry, it was a little inappropriate to laugh, so he couldn't help laughing again.

Li Chengqian continued: "Everyone is divided into groups, so you can carry out multiple groups of experimental test firing at the same time, and you don't need so many people to guard one." You can each experiment and write down the data, and then hand it in and discuss it! ”

After finishing speaking, he pointed to the flat terrain around him and said, "Here, dig a deep ditch for me, I didn't have to find a safe ditch to lie down just now." Fortunately, you have made a failure, if you get it on time, then you will all become barbecue! ”

After scolding, Li Chengqian paused for three seconds, and they felt that Li Chengqian stopped speaking, and then asked: "Your Highness, there is still a five-barreled rocket here, this is going to be test-launched?" ”

When Li Chengqian heard it,!

If the rocket really landed just now, then it could cause the five rockets here to explode together.

Tsk, these baby talents are all gone!

"Safety first, you know? You can't put all the rockets together here, if they explode, it's all over. Li Chengqian scolded again, "Let's move to the side first, and just leave one tube here for test firing." Dig a deep trench first, remove all the warheads for me, and leave only the necessary personnel here during the test launch, and everyone else will stand far away for me! ”

They should.

Cheng Lao waved his hand, and immediately sappers ran up to dig a ditch.

Engineers began to dismantle the warhead.

And Li Chengqian became the person who did not have to stay in his words, so he followed Cheng Lao Cargo Station away.

When they got it right, they started the test launch.

After ejaculating. They retrieved the rocket wreckage and gathered around. We discussed which kind of skin would be the most suitable.

After they discussed it, they didn't even pay attention to Li Chengqian. I ran back to the research room with a tube of tubes, and it seemed that I had some inspiration.

Li Chengqian was looked down upon, but he didn't get angry, and went his own way.

When I came back the next day, I saw that they were testing again.

A rocket was shot out, a hundred meters, two hundred meters, the height was getting higher and higher, more than two hundred meters later. He slowly slid down, flew out of 500 meters, and plunged into the earth!

Li Chengqian subconsciously covered his face with his hands, but there was no explosion as expected!

Oh, it looks like there are no more warheads.

"Okay, flew a mile away!" An engineer shouted happily.

Another person said dejectedly: "Dumb fire! ”

"Alas!" Everyone sighed together.

Li Chengqian walked over and asked, "What's wrong?" ”

"Your Highness, the fuse is out of order, and the small bomb inside has not exploded." The chief engineer said.

Li Chengqian was about to speak. The person who went to check on the rocket pulled the rocket out of the ground and waved a small red flag to this side.

Everybody knows there's a situation over there.

After a while, they sent over. said: "The fuse was broken, it may have been broken in flight, or it could be that the fuse was not arranged well. It's broken. ”

With the reason, they quickly wrote it down.

Then. They carried out a test firing of the second tube.

"Clear!" An engineer shouted.

So a large part of the people left the test range.

Li Chengqian also left with him and went to the shed in the distance. Watching them move skillfully, after igniting the fire, the personnel hurriedly jumped into the ditch and hid.

Observers and recorders, on the other hand, stood behind a newly built wall and watched the rocket.

The rocket erupted in flames and flew off.

The appearance of this flight is no different from the tube just now.

It seems that they have fixed the outer skin.

The rocket flew higher and higher, farther and farther, and suddenly in mid-air, the head of the rocket flashed.

Li Chengqian was stunned for a moment, but it didn't look like an explosion, so he waited a while and asked them what was going on.

The rocket was stuck in the ground again almost a mile away.

Li Chengqian walked over and asked, "What's going on?" ”

"Your Highness, the warhead exploded again in advance. That's a fireworks bomb instead of a warhead. An engineer said.

And halfway through the rocket's flight, someone had already run out to check. There are small flags planted on the road as a sign of distance, check the small flag, just now it exploded in the sky above the third small flag, so to say that it exploded in advance at 300 meters.

The flag was waved over there, and it was immediately recorded here.

Next, rocket after tube, tube after tube, was shot out continuously, and then one by one the records were recorded.

I was shot more than 30 tubes in one morning.

This production volume is quite high. It can be seen that Lao Li's side is fully supporting this side, and Cheng Lao is also working hard, and this group of people will rectify it.

In the afternoon, another group of people came to experiment.

This time, the distance of each rocket is different.

This is to test the amount and angle of gunpowder, to determine the distance.

The same angle, different amounts of gunpowder, and the distance shot out were all recorded. This can be used as a parameter later. When fighting, visually check how far the two places are, and if you want to use this angle, then check the parameter table, how much and how much rocket to use which stage of rocket, you can use it directly.

Although the launch of the rocket, what parabola to use to calculate, more accurate. But this stuff is too complicated. Now the data that comes out of this practice is also quite useful.

When others fired the guns, Cheng Lao sat next to him and sighed, as if his wife had died.

Isn't his wife Li Chengqian's future mother-in-law? Bah!

"Hehe, Uncle Cheng, what's wrong?" Li Chengqian walked over with a smile and greeted: "Could it be that the smell of gunpowder here is too strong?" ”

Could it be that you have tracheitis?

"People are more angry than people!" He sighed.

Li Chengqian couldn't help but be curious, is this popular?

"How?"

Today is a sunny day, the sky is very blue, there are only a few white clouds in the sky, Cheng Lao looked at the northeast and said: "Yu Chi Lao Hei, he has already left Chang'an!" ”

Wei Chi Lao Hei?

Li Chengqian is very strange, talking about what he does?

Cheng Laoxiang said another clueless sentence and said: "After the old man became the director of this gunpowder bureau, he will always stay here." Now the mission that was originally going out was the old man's, but now it was snatched away by Wei Chi Lao Hei. Not only did he snatch it, but the old man had to watch him go to the northeast to be arrogant, and the old man was staying here, like a nerd, this is a condescending old man! ”

In the end, Li Chengqian understood.

So that's what happened!

The old man is sick and unwilling.

Li Chengqian will not comfort an old man. But the old man found him, and his eyes glared at him with resentment.
