Strictly speaking, it's not oil.

It's just a semi-liquid that resembles petroleum on the surface. It is a very toxic substance.

This kind of substance does not exist in the starry world itself. It is completely a special product after the railgun bombardment. It's very difficult to break down, it's very difficult to handle.

It stands to reason that the technology of the interstellar age should be very developed, but in the face of this special petroleum-like semi-liquid, no suitable means of treatment have been found. This is also the reason why the countries of the starry sky generally oppose the use of railguns to bombard the surface of the planet. Because of the first shot, a large area will become a no-man's land for a long time, and it will spread to all sides.

This special semi-liquid has a strong corrosive ability, and will gradually corrode everything around it into a similar substance. It has a very long decay period. A conservative estimate is more than 3,000 years. In other words, the surface of the planet bombarded by space railguns has lost its use value for at least three thousand years.

The worst thing is that this semi-liquid has a huge danger to human beings. Don't say it's contact, even if it's close, you can be poisoned. Moreover, this kind of poison is still difficult to dissolve with current medical technology. Therefore, wherever the space railgun has been bombarded, human beings must not approach. It can be said that it is a veritable forbidden area of death.

Even, when semi-liquids are irradiated by stars, they volatilize a special gas. Organisms that come into contact with this gas are at risk of harm. If you inhale too much, you may die on the spot. As long as a certain amount is inhaled, it will be poisoned. This virulence is even able to prevent the replication of gene strands, which alter the latter. Causing genetic technology to fail.

Now, Liu Zhenbei understands a little. Why Wei Xuandu's lame leg can't be healed. It is very likely that it was affected by the space railgun, which caused the failure of genetic organ replication technology. From this point of view, the railgun is worthy of being the most terrifying weapon of the interstellar age. It's almost comparable to the "antimatter" railgun.

Even, its consequences are even more tragic than antimatter railguns.

Antimatter railgun is annihilation of everything. Devour it all.

The feeling that people can't survive and die is obviously more uncomfortable than swallowing it in one bite.

Fortunately, the railgun equipped with the Star Frigate is relatively weak. The maximum radius of coverage is only about 10 km. However, if it is a battleship, a star destroyer, or the like, the radius of the impact is hundreds or thousands of kilometers. This can cause great harm to the planet's surface. It could even lead to the entire planet becoming uninhabitable. It can only be discarded.

For example, if a battleship fires a railgun at Earth, it will create a death zone on Earth with a radius of several hundred kilometers. The toxic gases volatilized by the Death Zone will envelop the entire earth. Rapidly causes the death of all living things. No living thing can be born for less than 3,000 years. When humans get close to the Earth, they will suffer.

Because this special liquid is so terrible, people have given it a figurative name - "Satan's saliva".

If you want to talk about the starry world, what is the most terrifying weapon, it is undoubtedly Satan's saliva.

Simon's railguns are equivalent to the complete destruction of Ratchet City.

There is no possibility of rebuilding at all.

At least, not for 3,000 years.

Even, all the creatures that live in the dungeon will gradually relocate.

Because Satan's saliva will gradually corrode into the depths of the dungeon. Even if it's 5,000 meters underground, there's no way to avoid it. It's just a matter of time.

According to the general rate of corrosion, after six months, 500 meters of underground will also become semi-liquid.

In other words, the time left for the dungeon is only about half a year.

"We're going to protest!" Yan Jingxuan said angrily.

"What's the use of protesting." Liu Zhenbei pouted.

If an apology is useful, what do you need the police to do?

What is needed for the military if the protests are useful?

Protesting will only appear cowardly.

There is only a counterattack.

It is necessary to fight back.

Fight back with a land-based railgun!

Otherwise, the Simon warships will continue to fire railguns.

The first to be erased was Ratchet City.

Where will the second one be?

Longding City?

Longjing City?

If there is no strong means of counterattack, the entire Tang River control area will be fish on the chopping board, and there will only be a share of it to be slaughtered.

Others will destroy wherever they want. I won't care about your protests at all.

But if there is a land-based railgun......

Simon's arrogance was no longer forthcoming.

Keep going.

The cave gradually became narrower.

On the surrounding walls, you can clearly see the traces of renovation. Presumably, the Baili family only recently started repairing it.

"How far is it?"

"It's up ahead."

The group moved on.

Sure enough, the cave gradually became wider.

More and more traces of man-made are emerging. Naqoura Energy has already detected nuclear fusion reactors at close range.

Nuclear fusion reactors are not small. It is estimated that the power is at least a few hundred billion kW. The power of an ordinary interstellar frigate's nuclear fusion reactor is almost at this level. Inside such a deep cave, there is a nuclear fusion reactor of such high power, apparently in the service of land-based railguns.

The railgun does not use Naqoura energy.

It uses nuclear energy.

The more powerful the fusion reactor is, the more powerful the railgun will be.

Theoretically, there is no upper limit to the power of a nuclear fusion reactor. The sun itself is nuclear fusion! The vast majority of stars are.

But until now, mankind has not built a nuclear fusion reactor comparable to the sun.

Sure enough, it wasn't long before huge nuclear reactors appeared.

In the control room, Liu Zhenbei found the relevant power instructions.

650，000，000，000kw。

That's 650 billion kW. It is capable of providing 650 billion kilowatt-hours of electricity in one hour.

It is about equivalent to the installed capacity of 30,000 Three Gorges Hydropower Station in the ancient earth era.

"Su Hu."

"I'm here."

"What is the power of the world's largest fusion reactor at the moment?"

"Trillions of kiloks."

"Trillions?"

"That's right! Some extreme models of Star Destroyers use. The power supply of a Star Destroyer can meet the entire power needs of most planets. ”

"Got it."

Liu Zhenbei nodded thoughtfully.

Good guys, trillions of kw! That's 10,000 times the size of a fusion reactor in front of you!

No wonder the consequences of railguns can be so severe.

It's just that the energy it condenses is too terrifying.

"Look!"

"Hmm."

Liu Zhenbei walked over silently.

He saw a well.

A very deep, very deep, very special, very special shaft.

The wellhead is small, with a radius of only about one meter. Bottomless. The borehole is made of a special high-crystalline molecular material. Faintly shiny.

Standing at the edge of the well, it is as if you can see the projection of the entire Milky Way.

This is the charged track of the land-based railgun. 166 Reading Network
