At night, nearly fifty combat airships patrolled the holy city.

The secret muzzle and caliber of the multi-barreled cannon mounted below the airship's bow is frightening.

The loud noise from the turbo engine of the combat airship continued until dawn.

"A lot of air patrol units were found."

"We can get rid of them, but the quality is not good, and the quantity is useless."

"Their use is to find us or be killed by us, and then our goal will be exposed. The opponent's high-level combat power, including the archangel, may rush to us."

"This is a trap, we retreat."

The devil did nothing on this night, and the residents of the Holy City spent a fairly safe night under the loud noise.

Fortunately, the mechanical lifeforms of Zuan civilization themselves live in noise. They have long been accustomed to all of this, and this level of noise will not make them insomnia or irritable. Even in the high-decibel noise environment, the exhausted mechanical soul can still get a good rest as long as it sleeps, and can be fully engaged in work the next morning.

Conner Laboratories.

Today is a memorable day.

Alcohol is no longer an illegal product. After a vote in the parliament, it has successfully become a legal product.

For Conner Labs, they have a new funding supply chain.

With independent property rights, owning a self-developed wine production line, and being the only manufacturer and supplier, Conner Labs can be said to have made a lot of money.

As the only demander, Void Engine Bar, their boss actually didn't care about things like steel.

This is probably Connor's happiest.

Moreover, the raw materials used for high-quality liquor are very expensive, which leads to such a costly thing that no one dares to buy. Conner Lab ran around the holy city with the finished product. Five adults thought it was too expensive, and four adults thought the price was too high. The remaining one simply admitted that they didn't have the money.

A month’s goods require more than 1,000 steel bars. Shouldn’t it mean tens of thousands of steel bars a year? This is not a small amount.

After all, it is an emerging product, and most businesses are still in a wait-and-see stage.

The main purpose of Li He's coming to Conner Labs today is to buy the sole supply right of Conner Labs.

One of the most profitable behaviors in business is monopoly.

At the same time, it can also cooperate with Connor, who masters most of the Zuan technology, to arm the dark light.

The only supply right talked very smoothly, because except for the reason that no one could sell Li Hyuk anyway, it would be better to sell it only to Li Hyuk, and I could ask for more money.

The specific price concessions were left to Rigg and Connor for negotiation. As the bosses of the two parties, Lee Hyuk and Connor want to talk about more important things, such as... munitions.

"The revolver gun that appeared under the combat airship last night is not bad." Li He said with a smile.

"That is not for sale in military industry." Connor rebuffed. Although he made some gray trades, Connor also had a bottom line. This is why the Parliament tolerated her.

"I mean, the design idea of ​​the revolver gun is good. I have a similar weapon here with drawings and parameters. Can you design it using the material of the revolver gun?" Li He continued.

"I'll take a look at the drawings first." Connor became interested and reached out to ask for drawings from Li He.

Li He gave Xiao Luo a look, and Xiao Luo took out a stack of paper made of flexible metal.

"Vulcan? Gatling?" Seeing the name Connor on the drawing, asked in surprise.

Knowing experts don’t need to talk nonsense. Connor can see the value of this weapon at a glance, and it’s structurally superior to the revolver gun he designed.

This is obviously a mature technology. After at least a hundred or ten technical improvements, it can be a mass-produced guy.

"What is driving this? It is not mechanical kinetic energy, there is no energy storage, and there is no high-pressure gas storage tank. The structure is precise and reasonable. The requirements for the barrel are so high and the caliber is not large. This can really be used. Come to fire ammunition?"

Connor said curiously after watching it for a while.

She does not doubt the feasibility of this weapon, because such an excellent structure must be the data accumulated in the experiment after time, and then slowly modify the parameters and optimize it.

"Of course it can, and I think this weapon is better than your pneumatic revolver gun after it is designed." Li He gave Connor the answer he wanted.

"Huh, I use strong gas."

Strong gas is the energy extracted from the energy core, and the combustible gas made after adding special materials.

There are two types of charges required for the revolver gun.

One is a solid threaded bullet, and the other is this flammable gas.

The principle of the revolver gun is a bit similar to the car engine of the earth civilization. It injects combustible fuel into a closed cylinder chamber and ignites it by friction or other methods. The fuel in the closed cylinder chamber is instantly ignited to produce deflagration. The huge kinetic energy is released to push the solid threaded projectile to spin quickly in the barrel to maintain the stability of the bullet after it is ejected from the barrel.

"Don't you use the kinetic energy of physics?"

"Of course not, it's a... I can't tell you this for now." Li He only said half of the words, and finally decided to keep it secret.

Although the fierce gas can be regarded as chemical kinetic energy, this method of distributing ammunition largely limits the rate of fire of the revolver gun.

It’s just that every design of the revolver gun needs to ignite fierce gas in the barrel to cause a huge high temperature. The idea of ​​multi-tube rotation allows each barrel of the revolver gun to get sufficient cooling time, and it will not be caused by heat. The distance of expansion and contraction affects the firing fluency of the solid bullet thread when the barrel is overheated.

Gunpowder is one of the four great inventions of an ancient civilization. If paper carrying knowledge represents wisdom, then violent gunpowder represents force.

The two appear together, and the combination of wisdom and force is enough to create a country or even a civilization.

Li He will not tell Kang An about the formula of gunpowder for the time being. The two are just collaborators, not allies.

Li He considered that if there is a suitable opportunity in the future, he can tell Connor the concept of "bullet".

The combination of propellant and propellant, even if strong gas is used instead of gunpowder, as long as it can solve the problem of the primer, it is very interesting.

Maybe in the future we can give the devil or the undead army a surprise.

Later, because of the huge transaction amount between Li He and Connor Labs, Connor kindly invited Li He to visit the shooting experiment site of the rotary gun.
