……

Although I couldn't find a reason for the surprise, I still didn't understand her idea.

"Anyway, I like to go and sleep underneath, sleep quietly alone!" She said.

Then she said, "However, let a little shrimp go down with me!" ”

This is contradictory, and I like to sleep alone, and I want someone to accompany me, what kind of trouble is this?

"Well, Ah Zhen likes it, it's up to you." Su Mi agreed first.

So, the eldest sister of the hippo asked the palace maid to take her things and go downstairs to find the biggest and best room.

"Do you know what's wrong with her?" Li Chengqian asked Su Mi, Su Mi smiled and said nothing, then turned around and entered the room, hummed a song, and went to prenatal education.

Don't tell me?

If you don't tell it, forget it, who is rare!

Li Chengqian went to the balcony to take a look at the scenery, he hasn't been here for half a year, so nostalgic!

A small figure walked over and leaned next to Li Chengqian, Li Chengqian turned his head, saw Xiao Chen, turned his head again, and continued to look at the pool below.

Xiao Chen smiled and said, "Your Highness, the concubine knows why Ah Zhen went downstairs to sleep." ”

"You're laughing like this, what kind of thing is it to say it?" Li Chengqian was curious.

Xiao Chen made a grimace and said, "Haven't you noticed that Ah Zhen has become shy recently, she is no longer the girl who didn't understand anything and didn't care because she didn't understand, but now it's starting to change, so she's afraid of seeing you enter the concubine's room!" ”

Li Chengqian listened, and the muscles of his brow twitched.

That is to say, the eldest sister of the hippopotamus has developed into puberty, and the psychology of adolescent girls is certainly a spectacle.

"So that's what happened. Then ignore her. ”

Li Chengqian smiled.

Moved back into Nishiike-in. Blowing the wind of natural air conditioning, Li Chengqian and their joy have increased a lot. At night. Blowing a cool breeze and telling stories. It was very pleasant.

And more than a month has passed, and the research and development progress in the Gunpowder Bureau is also very fast.

When Li Chengqian went to see it that day, they were testing again.

A two-meter-long rocket was launched.

After shooting out, I went higher and higher, 200 meters, 300 meters, 400 meters, almost 500 meters. before slowly sliding down.

Finally, it landed on a dirt slope two miles away.

It was two seconds before a whistle was heard.

It's not an explosion, it's like some kind of air blowing.

"Okay, it worked!" Engineers and elementary mathematicians shouted with joy.

"What was it just ringing?" Li Chengqian asked strangely.

An engineer who was held back by Li Chengqian replied: "Your Highness, we have found that when the gunpowder burns, it will produce an air current, this air flow. It's the same as the breath that comes out of our mouths, and if our mouths can blow the flute, then the flow of gunpowder can blow things too! So we put the front warhead in place. It was replaced with an iron head that would be blown and filled with gunpowder. When the rocket is fired, the fuse is gone. You can ignite the gunpowder, and the air flow of the gunpowder ignites. You can blow the iron head so that we know when the fuse was detonated! ”

Such a complex process. After listening to this, Li Chengqian nodded, it is indeed good.

"Clear!" An engineer shouted.

At this time, the personnel behind the rocket that recorded the launch to the destination waved the flag, and then the launch began again.

So everyone evacuated, and Li Chengqian went to a distance and watched them shoot the rockets one by one towards the dirt slope.

Eight out of ten tubes are successful, and this success rate is very high.

Li Chengqian nodded.

The chief engineer came over to report to Li Chengqian that tomorrow and the day after tomorrow and the day after tomorrow, he could put a warhead on it for test firing.

And after the successful test launch, the rocket was also successful.

Li Chengqian tapped his fingers on the table and said, "I feel that our requirements are not high enough!" ”

Hearing this, the chief engineer hurriedly sat up straight and listened to Li Chengqian's opinions.

"Now, we can shoot two miles away. This distance is not bad. It is also very good and practical to use on the battlefield. However, we also need to be far away. It's better to shoot a rocket for ten miles! Li Chengqian said: "Of course, it is not good to put forward such high requirements in such a short period of time, and the road still has to be taken step by step." However, we are now going to put on a show, to show the enemy, so we should come up with the strongest thing. ”

His face was grim, and he said: "Therefore, I now ask you to make the gunpowder thrust bigger, and adjust the angle for me, so that you can shoot five miles away in one tube, hit the three-zhang high city wall, and bomb half of the city tower!" ”

The chief engineer was stunned.

None of the experiments they did before flew out of Wuli, and now as soon as Li Chengqian's words came out, the pressure on him was still very great.

But when I heard that I flew five miles away, hit the three-zhang high city wall, and bombed down half of the city tower, such a scene was too exciting.

The chief engineer stood up, gave a military salute to Li Chengqian, and answered!

Li Chengqian patted him on the shoulder and said, "I'm optimistic about you, go for it!" ”

Immediately, he asked strangely, "Is the rocket over there shooting too fast?" ”

The launch of the rocket was to be checked beforehand, and they carefully checked it three times in a row. After launching, it is also recorded, and this process makes the rocket launch process only one or two minutes, and the rest in the middle is more than ten minutes, or even half an hour.

Now, the rockets are constantly spewing out like fireworks, and they have to make Li Chengqian strange.

So he asked the chief engineer and looked at the launch pad.

The chief engineer also looked over.

Then the two of them turned pale.

"Here, Princess Huazhen is here!" The chief engineer's jaw is dropping.

Li Chengqian saw that in the trench, a woman wearing a cyan power suit, jumped out, lit a torch, and the rocket burned her buttocks, and she hurriedly jumped into the trench. Whew, after the rocket erupted, she showed her head and shouted excitedly. Then she jumped out and pointed at the soldiers to keep moving the rockets, she hadn't had fun yet!

This is a rocket as a firework!

Li Chengqian was so angry that he ran over, pulled her ear, and said, "Why did you come here?" ”

"Ahhh Sister Hippo threw away the torch, quickly covered her ears, and shouted.

When she saw Li Chengqian, she didn't even dare to resist.

"It's Sunday, it's Sunday off!" Sister Hippo hurriedly explained!

Li Chengqian pinched his fingers and counted, it was really Sunday again.

After this hippopotamus sister was brought over by him once, every Sunday, he came here to play with cannons.

I just happened to encounter a test-fired rocket today, so I ran up and went crazy.

"You can't play with these rockets!" Li Chengqian blamed.
