After giving Ye Hao a one-month long vacation, it is certainly impossible to stop the follow-up study of gunpowder.

Luo Ji will hand over the recipe copied from the wall to Zhao Lei.

Under the circumstances that the Minister is not in tune, Zhao Lei has been a deputy minister for so many years. It is obviously very stable to start things.

It is obviously impossible for this gunpowder formula to be immediately put into production.

Although the power of the explosion has been seen once.

But to get a lot of deployment, you need more detailed data and a steady success rate.

This kind of thing is left to Zhao Lei to do the accident.

Of course, in order to avoid the situation of disturbing people caused by explosions from time to time, Luo Ji temporarily transferred the test site of the Ordnance Research Department to the outside of the city.

Then the time flies, and a month later, Ye Hao, who was released from prison, decisively found a Luo series with a resentment.

"Your Majesty, my reward?"

In this regard, Luo Ji decisively turned a blind eye.

"The office building of the Ordnance Research Department has been bombed by you. It is still being rebuilt now. Do you dare to come and reward me?"

Ye Hao, who heard this, apparently flashed a guilty conscience on his face.

Then he hurriedly slammed his head and played a role.

"I don't care! Your Majesty said that I only need to study the formula of gunpowder, you will give me a new weapon design! I have researched it now, give me the quick to give it to me..."

Looking at the standing below, there was no leafhopper that was full of rolling, and Luo Ji suddenly felt that his brain had some pain.

At the same time, in the month of giving Ye Hao a long vacation, under the supervision of Zhao Lei, the stable formula of gunpowder has indeed been made.

At this moment, the research on weapons and equipment should be kept up.

Thinking of this, Luo Ji sighed heavily.

Then I took out a thick stack of designs that I had prepared.

This stack of design drawings is the design of the gold-level stone gun that he opened before the gold treasure chest.

Seeing the leaf of the design, it is like a cat smelling fishy, ​​both eyes are shining, and I want to take the design away.

Losing a lot of eyes and quick hands, quickly put the design of his hand to the top of his head, while avoiding the arrest of Ye Hao, he smiled and said...

"We will say it first. If you want to make another incident this time, I will give you a three-month long vacation. Do you understand?"

Listening to Luo Zhikou's three-month long ‘long vacation’, Ye Hao’s whole face was decisively white.

"Your Majesty, are you a devil?"

"Have you heard?"

"Hey, I heard that."

"take it."

During the speech, Luo Ji handed the stack of designs he had in his hand to Ye Hao.

A leafhopper who took over the design was naturally turned up on the spot.

On the design drawing, the shape of the stone cannon is undoubtedly novel for her.

After looking at two pages, Ye Hao couldn’t help but ask...

"Your Majesty, is this an upgraded version of the mattress?"

When I heard this, Luo’s brows were slightly picked, and it was really a loss that Ye Hao could see the shadow of the bed from the stone gun.

However, this statement is not entirely correct.

"If you want to say it, it should be a weapon that combines the characteristics of the mattress and the catapult."

The positioning of the mattress and the catapult is itself equivalent to the ancient siege cannon.

The characteristic of the mattress is the penetration force.

The characteristics of the catapult are the destructive power of the blunt.

The cannon combines these two features at the same time.

However, for the stone cannon, Luo Ji did not have much expectations.

At best, this is the key to let his Wanzhou civilization enter the threshold of the 'firearms'.

As I said before, the range of the stone guns is not as good as the three bows and the back guns.

At the same time, the accuracy is still quite poor.

Instead of making a large number of stone cannons, it would be better for him to continue to use the three-bow bed and return the gun.

But after that, Luo Ji soon wanted to understand one thing.

What he opened was indeed the design of the stone gun.

But there is no rule that he can only shoot stone cannons!

He is a modern man, can't he improve on this basis?

Early cannons, collectively known as muskets.

The origin of this name is because the inside of the barrel is smooth.

The stone guns are obviously also scored in the category of the musket.

The common problem of the slippery gun is that the range is close and the accuracy is poor.

But Luo Ji can be improved at this point.

Based on the design of the stone gun, it is not a good idea to directly improve it into a line gun.

The biggest feature of the line gun is that the inside of the barrel is engraved with a twist line.

Therefore, when the cannon is fired, the projectiles that fly out will rotate along the trajectory of the inner rifling.

So that the less stable shells can achieve a stable flight effect.

At the same time, it also significantly improved the range and accuracy of the cannon!

Of course, the guns that want to make the line guns have quite high requirements on the manufacturing process and technical strength.

There is also the structure of the entire gun body. Due to the change of the firing method, an entire structure has to be changed.

However, Luo Ji is not afraid, he has the technical and scientific power of human and goblin at the same time, and Ye Hao, the top ordnance master.

Can this thing still be difficult for him?

Between the thoughts and the flight, Luo Ji directly referred to the design drawings and gave a simple explanation to Ye Hao.

"This part is called the barrel, this is the shell, and this part of it is used to fill the gunpowder."

"But on this design, I have missed a bit. The internal design of this barrel will cause the accuracy and range of the shell to become too bad, so..."

During the talk, Luo Ji quickly took out a design on his desk~lightnovelpub.net~ The design was obviously drawn by Luo Ji, the main content is the internal structure of the line gun, and some His vision for the transformation of the overall structure.

However, the structural design of the cannon is sensitive information. After all, there is not much information that can be found. To do this, he obviously tried his best. Can he use the limited information and ideas he provided to make the line guns? This depends on the skill of Ye Hao, the master of ordnance.

Ye Hao, who took over the design, quickly looked up.

"It turns out that if such a trajectory is made on the inside of this barrel portion in advance, when the projectile is flying out, it will naturally rotate along these trajectories, and the high-speed rotating projectile will become more stable."

While talking, Ye Hao, who was excited, couldn’t help but stretch his hand.

"This looks like a simple design, but it can effectively increase the range and accuracy of the projectile. If you are really good, you can come up with such a design!"

"..."

"But I think if you want to do this, the shape of the shell should be changed a little, and the surface should be the same with the corresponding trajectory, so the effect can be better, how about the cone?"

"..."

"There is still this structure here, I always feel that something is wrong, kneel, what do you say?"

"..."

Terrible, is this the difference between top geniuses and mortals?
