……

"Your Highness......"

Very resentful voice.

Li Chengqian also felt sorry for Xiao Chen with dark circles.

I don't know how long I waited naked in the quilt last night.

Now the circles under my eyes are dark, what a sin!

I can't sleep well, my mouth is light in the morning, and the porridge is not fragrant.

Take a look over there, Wu Zhao sat there quietly drinking porridge, taking small sips, very ladylike. Although she is very quiet, how can Li Chengqian feel that she is rejoicing in disaster?

This demon girl has ruined the happiness of two people!

Although he was blaming Wuzhao, Li Chengqian still couldn't say it, and he had to coax Xiao Chen.

He drank three and a half bowls of porridge, and the remaining half bowl, he put it in front of Xiao Chen and said:

"I can't finish eating, you help me drink!"

Then he stood up, wiped his mouth, and said, "I'm going to work!" ”

After speaking, he went over and touched Su Mi's belly and went out.

"Eh, wait for me!" The hippopotamus grabbed a bun and chased it out.

While eating, she said, "You promised me yesterday that you would take me there!" ”

"Let's go!" Li Chengqian beckoned.

Outside, Lao Long led a horse and was waiting for Li Chengqian.

Why does this horse look familiar?

"Isn't this Uncle Ma?" Li Chengqian asked with a smile.

"Shhh ......" the dark horse cried. The voice is very human, like laughing, like saying hello to an old friend.

Li Chengqian smiled, walked over, and patted its horse's head. "Yo, are you happy to be like this?"

The old dragon said humbly: "Recently, I heard from the horseman that the thunder has been restless. I could see that it wanted to run, so I tried it to ride it. It was sent to His Highness. ”

Li Chengqian nodded at Lao Long and smiled.

Then he rode on the Thunderbolt.

When it came to its horseback, I could feel the thunder trembling in its excited body.

It seems that this is the fate of horses, and being ridden by others is where the value lies!

The eldest sister of the hippopotamus rode on Li Chengqian's original horse, patted it very boldly, and then walked forward, walked ten meters, and turned back.

Back and forth. It's mixed with horses.

"Alright, let's go!" Li Chengqian said.

As soon as his voice came out, Uncle Ma under him automatically walked forward.

Other horses, on the other hand, need to pinch the horse's belly with their feet to get the horse to move forward.

Along the way, Li Chengqian didn't have to control the horse, it could follow Li Chengqian's words, or other people's words. And to see how the other horses walked, and walked the right way.

When I walked out of the palace, there was a pony waiting at the door.

Li Chengqian was stunned when he saw it, what is going on?

"Your Highness. The mother of the horse wants the pony to come out together, otherwise they will be in the stable for a long time, and there is no way. Thankfully, it agrees to let the pony wait here. Mafu said.

Uncle Ma under him screamed softly, as if he was pleading with Li Chengqian.

"Alright. Go along. Li Chengqian patted the horse's head and said. But you're going to have to watch out for the ponies, and if you get into trouble, you're in charge. ”

Uncle Ma responded.

The groom muttered, "The ponies can't even stand on their feet, where can they run?" ”

"Woo......" Uncle Ma heard it, screamed dissatisfiedly, and glared at the groom.

This is an old hero horse who has been fighting for more than 20 years, and his body is also dyed with a lot of murderous energy.

The groom is just a groom, where he has been on the battlefield like an old hero horse, and he was frightened for a while.

He took two steps back, quickly lowered his head, and then honestly acted as a nanny, taking care of the pony.

The pony ran over to Uncle Ma's side one by one.

Uncle Ma walked forward.

The pony immediately chased.

However, it walked a few places, slammed, fell, and almost reached the ground on all fours.

Uncle Ma is not controlled by Li Chengqian, but he is walking.

Last time, Li Chengqian had seen how much it loved the pony, and thought it should stop and take care of it.

But when he saw that he did not look, he ran ahead.

And the pony behind him kicked his limbs several times before he slowly got up, and then chased after Uncle Ma.

Li Chengqian heard a thud on his horseback.

He couldn't help but feel distressed, this was too cruel.

But Uncle Ma under him didn't care about it and continued to walk forward.

Li Chengqian grabbed the reins of the horse, and Uncle Ma screamed dissatisfied.

When Li Chengqian and Uncle Ma were in a stalemate, after falling twice, the pony finally ran over to his mother's side, rubbed his mother's thigh with his body, and Uncle Ma kicked the pony aside.

The pony is also cheap, and after kicking it down, it quickly stands up, and then comes over to rub it again.

But at this time, Uncle Ma had already walked forward, so he had to chase again.

So, along the way, the pony kept chasing and falling, and Uncle Ma began to just go forward.

But then he still found that Uncle Ma's speed had slowed down, and he deliberately waited for the pony for a while, and when the pony arrived, it was almost there, and it resumed its speed again.

Oh, I understand, this Uncle Ma wants to come over to be Li Chengqian's mount, so that it can take the pony around, and the pony is congenitally insufficient, now take a few steps and fall, Uncle Ma is going to increase the amount of exercise by letting it, and then help it recover the nature of the horse!

Thinking about this, Li Chengqian also let it go.

But in this way, the road is much slower.

It took me half an hour to get to the gunpowder bureau, but now it took more than an hour, and it was almost noon from the morning to the morning.

Li Chengqian didn't care, but the eldest sister of the hippo looked at the pony cute and looked a little like her, so she circled the pony behind.

When he arrived at the gunpowder bureau, Li Chengqian asked people to look at the mother and son, and then he went inside.

"Your Highness, why are you here now?" Cheng Lao asked strangely.

Li Chengqian didn't explain about Ma: "I already have a plan, make rockets." ”

Cheng Laoxiang waited here for a morning, and he was depressed. When I heard this, I thought that Li Chengqian was looking for inspiration. And dragged on until now, so I heard him say this. His eyes lit up and he asked, "What is it?" ”

"Let's go inside." Li Chengqian walked directly inside.

The old dragon in the back followed in with a large pile of drawings.

Cheng Laoxiang took Li Chengqian to the laboratory dedicated to him, and Li Chengqian took a cursory look and found that all the tools were available.

He took the drawings and opened them for Cheng Lao to see.

"Huh? This is? Cheng Lao looked at it seriously.

On the drawing, the shape of the rocket is drawn, and the other is the component and function.

This was followed by a schematic diagram of what the rocket would look like during the launch, and finally landed at the target. Explode!

The whole drawing is very vivid, Cheng Laoxiang thought that Li Chengqian had drawn the principle, thinking that he couldn't understand it, but he didn't expect it to be this kind of rendering, and he could understand it when he saw it!

"If you do this like Your Highness, you can launch it in front of everyone, and then fly to the place where we put the puppets, and then explode. This launch is very mysterious, no one can think of why, and this explosion. Who knew that the rocket we could fly had iron nails in it, and thought it would explode like this! "Cheng Lao is very satisfied with this feature.

He slapped his thigh and said, "Let's take it to that Gao Shilian right away." Let him comment on this thing, can it be used to deter the envoys of the enemy country! ”

"Don't!" Li Chengqian waved his hand. He said: "This rocket is not only used for deterrence. And it can also be used as our strategic weapon, and if it is made, it can be useful to our Datang. Didn't we think about how to launch the Celestial Maiden Flower Bomb before, but now that we have this, it's okay! ”

Cheng Laoxiang's eyes opened, slapped his thigh again, and said, "Yes, why didn't I expect it, it seems that His Highness's brain is still bright!" ”

"When did I lose my time?" Li Chengqian glared at him angrily, "Go and find the best gunpowder engineer and start construction together!" ”

Li Chengqian only uses his brain, not his hands, and this style must be maintained.

Cheng Laoxiang became Li Chengqian's errand and went to pull the engineer over.

More than a dozen engineers arrived, and they were all crowded in Li Chengqian's studio. Fortunately, this studio is vacated for Li Chengqian, a prince-level person, so it is big enough, and it is not too crowded for so many people to stand and give lectures.

After Li Chengqian showed them the drawings, he then began to lecture.

The first thing to talk about is that gunpowder is used as a thrust.

These sub-engineers have been working on gunpowder packs and bombs, thinking that gunpowder can only be exploded, and now when they hear Li Chengqian's statement, they are a little confused.

Li Chengqian gave a simple example: "Isn't fireworks sent to the sky with gunpowder? Little flying arrows, isn't it just that the butt ignited gunpowder and flew into the sky? ”

As soon as this example was said, everyone accepted it, so they began to count the spark thrust and how to do it.

"This rocket will be something that needs to be divided. From the thrust, to the warhead, that is, the bomb placed in front, the skin, as well as the ballistics, the angle, these all need to be done by Seiko, so among you, see how you want to divide it, it's up to you to decide! Li Chengqian said.

This project cannot be carried out by them together, and the division of labor will be better able to complete the task.

Li Chengqian went on to talk about loading warheads.

The warhead will explode when it flies to the target, but this fuse has to be considered, how to determine that the fuse will detonate when it flies to the target, and will it explode halfway?

And it can't be after arriving at the target place, it doesn't explode for half a day, and it is taken by the other party to be buried.

The fuse can be lit after the thrust gunpowder is burned, and then it is lit along the fuse.

In this way, it is necessary to calculate the amount of gunpowder of the thrust, as well as the distance of the flight, and the ignition speed of the fuse.

And another problem that arises is that when fighting, the distance is not all the same, if you want to shoot far, the amount of gunpowder is not enough, and if you shoot close, the amount of gunpowder is wasted.

So the amount of gunpowder has to be graded again.
