God-level prince of the Tang Dynasty

Chapter 743
Li Chengqian arrived at the Weapons Research Institute very quickly. When he first arrived there, Li Kai hurriedly greeted him.

His expression was agitated, making him a little slurred.

He kept saying some strange things from his mouth.

Li Chengqian couldn't understand what he was talking about.

"Li Kai, speak slowly, I really don't understand what you are talking about?"

Li Kai calmed down for a while, then took a deep breath, and said: "His Royal Highness, we have built that cannon, and tested it, and the results have come out! It is very powerful! It is really shocking! Great! ...

Datang will be even stronger!I have never seen such a powerful thing, His Royal Highness is really a great talent...

No one would have imagined that a small cannon could have such a huge destructive power...

Cannons are as powerful as men..."

Li Kai chattered on and on, and he had repeated many times about the power of the cannon.

Of course, this is considered normal. If it was an ordinary person, he would have fainted from excitement.

"Okay, stop talking!"

Only then did Li Kai stop, but he couldn't stop his excitement.

Very short of breath.

Li Chengqian was also very excited when he was told, he said: "Take me to have a look!"

"Yes Yes Yes!"

Li Kai walked ahead and led Li Chengqian to a clearing. This clearing was very large, 500 meters wide and [-] kilometers long. There was a big iron cylinder on the short side. Needless to say, it was a cannon.

Li Chengqian stepped forward and was about to touch the cannon barrel, but was stopped.

"His Royal Highness, wait, this cannon has been tested many times just now, and it is still a little hot. Don't touch it!"

Looking at the white smoke still rising from a cannon, it can be seen that it was still bombarding just now.

Li Chengqian stopped his movements and looked at the cannon carefully.

This is a cannon based on the Hongyi cannon.

The Hongyi Cannon was originally a long naval gun made in Europe around 1600. It was introduced to China in the late Ming Dynasty, and it was collectively called the Hongyi Cannon afterwards.

The Hongyi cannon has many advantages in design. The barrel is long, the wall of the barrel is thick, and the caliber is large.There are cylindrical lugs on both sides of the center of gravity of the gun body. The gun can adjust the shooting angle based on this axis, and the shooting range can be changed according to the amount of gunpowder. There are front sights and rear sights, and the trajectory is calculated according to the parabola, with high accuracy.

Its length is about three meters, its diameter is about ten centimeters, and its weight is more than one ton.Hongyi cannons are mainly made of copper and iron. Although copper is used as a material, it is not easy to explode the chamber, it is not easy to have pores, and it even has a longer lifespan and other advantages.

While Li Chengqian was thinking, Li Kai brought a cannonball.

The cannonball is very heavy, it looks like it should weigh about ten catties.

"This cannon consumes a lot of copper and iron. If it is to be mass-produced, I am afraid that more copper will be used! This is a cannonball, which can be fired up to ten miles away. Our space here is limited. Only Provides wall covering four miles away."

Following the direction Li Kai pointed, Li Chengqian saw the wall in the distance, it was full of scars, and it was full of traces of cannon blasts.

"You don't have to worry too much about copper. The king's monetary policy will be accelerated. The copper coins will be discarded as soon as possible, and the decorative copper coins will be turned into materials for my cannon."

Li Chengqian said that the lack of copper is really nothing, as long as there are copper coins.

Paper money replaced copper coins, and he would collect all the copper and use it to make cannons.In addition, for some mineral matters, he will also strengthen and increase mining efforts in order to ensure sufficient supply.

"Yes! Does His Royal Highness want to see how powerful it is?"

Li Kai has already brought the cannonball in front of Li Chengqian.

"Let's see how powerful it is!"

Although Li Kai said a lot, the real situation has not been verified yet, so Li Chengqian also wants to see it, so that he can pretend for a while.

"Yes!"

And then, everyone got busy.

"You guys, pack gunpowder!"

Li Kai gave an order, and the people below began to load the gunpowder, compact it with things, and finally put the shells on.

When everything was ready, Li Kai said: "His Royal Highness, please move to the back!"

"okay!"

Then Li Kai took Li Chengqian to a place behind.

Because the cannons are fired every once in a while, the power is huge, and if they get too close, they may damage the eardrums.Cause irreversible damage, in that case, the gain outweighs the loss, which is the same as when Li Chengqian asked everyone to cover their ears.

When everything was ready, Li Kai shouted: "Fire!"

Then someone ignited the fuze, accompanied by a hissing sound.

boom……

After a loud bang in the sky, there was another muffled bang, and white smoke rose from a distance.

In Li Chengqian's eyes, a small mound of earth was blasted to pieces.

It is really exciting to see such a shocking scene.

"Good! Well done, Li Kai, you have made another great contribution!"

Li Chengqian's interest is very high, this Li Kai is really a genius, it's no problem to build these things.

Li Kai hurried forward and said: "This is the prince's guidance! The villain just did what you wanted."

Having said that, not everyone can do this. Li Kai is still very talented.

"Hahaha! You deserve a reward! This king rewards you with a hundred taels of gold!"

"Thank you, Your Royal Highness!"

As soon as Li Kai finished speaking, the system gave a reminder.

Congratulations for completing the task of inventing the cannon, and you will be rewarded with 20 points.

Start task five: Build 40 cannons within half a year!Award [-] points.When the time is up, those who have not completed the task will reset the calculation!After clearing, the reward for the second mission will be reduced to one tenth, and so on until the reward disappears, and the mission begins!
Half a year is very loose. For Li Chengqian, it may be completed in three months.

He fell into deep thought, Li Kai said at this time:
"I don't know what name His Royal Highness wants to name this cannon? I want someone to engrave a seal on the cannon!"

"Huh? Let's call it the Zhenguan Magic Cannon. You can engrave it now!"

"Zhenguan Magic Cannon, what a name!"

The name is just a synonym, you can call it whatever you want, but some rulers may care more about it.

As for the name, it is best to name it after the year.

After all, this thing was produced during the Zhenguan period, it is called Zhenguan Magic Cannon, there is nothing wrong with it.

"Also, Guan Lishi invites His Majesty to have a look!"

Well, before Li Shimin can take a look at everything, he has to talk to Li Shimin again, produce a lot of cannons, and when the cannons are produced, it will be the dawn of the expansion of the Tang Dynasty, what about Turks, what about Tubo, and Goguryeo?Who does not cry at his feet?
"Yes! His Royal Highness!"
