The Return of the Black Technology of Immortal World

There is actually more than one place like this.

Because the core of Mars is not worth mentioning compared to its body.

But you need to know that the diameter of Mars is 6679 kilometers.

Even if the diameter of the core of Mars is only one-twentieth of the diameter of Mars, it is still a behemoth with a diameter of 300 kilometers, and a surface area of ​​more than one million square kilometers.

Obviously, a mere talisman array is like a slightly larger piece of dust. Let alone controlling it, it is impossible to even have a slight influence on such a behemoth.

Therefore, in Yang Qing's design, there are a total of ninety places where such talisman formations can penetrate. The locations chosen are places with almost no obstacles and where the flow of magma or mantle material is not so intense.

Thanks to the high efficiency of spiritual energy, the fully expanded talisman array that landed on the core of Mars has a huge range.

The area of ​​influence of a talisman array is only a few hundred square kilometers, which is far from the surface area of ​​the earth's core.

However, after all the talisman formations are unfolded and connected with each other, the area affected will instantly increase hundreds of times, like a fishing net, directly wrapping the core of the earth.

To wrap the entire earth core, only ten talisman arrays are enough. The reason why there are ninety talisman arrays is completely redundant design to prevent the talisman arrays from failing somewhere and causing the mission to fail.

When the talisman array is connected, it will automatically carve runes on the surface of the earth's core, or even inside it, thereby achieving the purpose of controlling the earth's core.

After all, Mars is technically a dead planet.

Perhaps billions of years ago, life flourished on Mars, but today, billions of years later, it is dying.

Now, through Yang Qing's asteroid impact, Mars has become active again.

But this kind of stimulation based on external forces is not a long-term solution after all.

The runes carved in the rune array actually have no special meaning.

But when necessary, Yang Qing can use such runes to inject spiritual energy into the core of Mars.

In this world where spiritual energy is exhausted, there is no need to worry about the problem of being unable to fuse. All materials in this world are basically open to all comers.

The reason why we didn’t add spiritual energy to the core of Mars right away.

This is entirely because in order to feed the core of Mars, the amount of spiritual energy required is also massive.

According to Xiao Ai's calculation, almost all the energy radiated by the sun to the Blue Star in a year is converted into spiritual energy, which is barely enough for the earth's core to absorb.

So it’s not that Yang Qing doesn’t want to, it’s that he can’t do it.

If the earth's core is not fed and only a small amount of spiritual energy is injected, then the material in the earth's core may undergo some kind of change.

I don't know whether this change is good or bad, but Yang Qing can't afford to gamble. He can only control the core of Mars first, and then raise the stakes when the spiritual energy is sufficient. At least he still has a certain degree of confidence in this kind of control.

And the giant talisman array has more uses

Such a giant talisman array is not only more powerful, but also can last longer because it can convert the thermal energy of the earth's core into spiritual energy.

Naturally, Yang Qing doesn't know how long such a transformation can last. After all, this is Mars and the solar system where spiritual energy is lacking, not the ancient world where spiritual energy is rich. There has never been a chance to do similar experiments.

In short, they circled Mars in a large circle and spent several hours before completely placing the talisman array.

The reason why it is so convenient is entirely because their portable aircraft can fly at dozens of times the speed of sound of Blue Star and can visit the entire surface of Mars in less than an hour.

The physical fitness of the several people on board the aircraft can withstand faster acceleration without the need for buffering by the aircraft.

As for making holes on the surface of Mars, it's even simpler.

The large spacecraft in the outer space of Mars has a large fusion reactor with surging power. Opening windows on Mars is just a small experiment.

If a real full-power laser is launched, its effective attack range will reach

The extent to which everything above fifty kilometers below the surface of Mars has evaporated.

After completing these tasks that required entering the Martian atmosphere, a few people had no intention of visiting the surface of Mars, which has an extremely harsh environment.

After all, now, after the ninety holes opened by lasers have disappeared, the surface of Mars is once again covered by thick dust and clouds. In addition to the lightning that cuts through the sky, there is also the faint light emitted by the radioactive elements. There was no light, it was a completely dark water world, and there was indeed no scenery to see.

As they left, the talisman formations that entered the magma layer of the earth's crust shrank into a small ball, falling towards the core of the earth under the influence of Mars' gravity.

The hot magma is naturally not water. It is much denser than water and brings greater buoyancy.

If the talisman array hadn't shrunk enough and adopted part of the gravity engine principle in consideration of the poor fluidity of the magma below the earth's crust, which greatly increased its mass, it would have taken much longer to reach the earth's core. It will be calculated in hundreds of years.

Not to mention that on the way, the flow of magma will take the talisman array away from the originally planned position without obstacles, causing the talisman array to get stuck.

Therefore, not only will the talisman array shrink into a ball immediately, but it will also form a shield on the surface that can generate high temperatures.

The temperature of this shield will be as high as 10,000 degrees.

After all, the temperature in the depths of the earth's crust and the mantle has reached over 5,000 degrees. Materials that can remain unmelted in this environment will at least have a melting point above 5,000 degrees.

Although in the real world, no substance can withstand temperatures above five thousand degrees without melting.

The metal with the highest melting point is tungsten, with a melting point of 3410 degrees Celsius.

The highest element is carbon, with a melting point above 3500 degrees Celsius.

The substance with the highest known melting point is a hafnium compound, tetratantalum-hafnium pentacarbonate, with a melting point as high as 4215 degrees Celsius.

However, this is a synthetic substance that almost does not exist in nature, so in nature, there are almost no substances that exceed the melting point of elemental carbon.

Although the high pressure inside the earth's crust will affect the boiling point of liquids, it has little effect on the melting point.

In the same way, even though the 10,000-degree high temperature above the shield still cannot vaporize the earth's core and mantle materials with terrifying pressure, it can make magma-like fluids thinner, thereby increasing their falling speed.

So very soon, after the high temperature shield took effect, the falling speed of the talisman ball suddenly changed from slow to as fast as a stone falling into the water.

However, even if the stone falls quickly in the water, it still has to cover a long journey of more than 3,000 kilometers to reach the core of Mars.

Just like raindrops falling from a high altitude, after the balance of gravity and air resistance, they will maintain a level of 2 meters per second for small raindrops to 8 to 9 meters per second for large raindrops.

After entering the talisman array inside the Martian lava, its equilibrium speed is slightly greater than this, almost 20 meters per second.

That is a speed of 72 kilometers per hour.

Then the time for them to reach the core of the earth is almost 41 hours later.

This time is not long. In fact, as the internal pressure of Mars increases, the density of the mantle material becomes greater and the resistance becomes greater, and the closing speed of the talisman array will further decrease.

In fact, according to Xiao'ai's calculations, this time will be about ten days, which is already quite fast. After all, the underground pressure is extremely high and the environment is even worse.

The most important thing is that even with Yang Qing's ability, he cannot directly see the scene inside the planet.

In the end, indirect observations can only be made by relying on the powerful penetration of neutrino detection equipment.

After several years of operation, neutrino detection equipment has accumulated a lot of experience. Although it is indirect observation, it is actually almost the same as the real situation.

At least the location it chose to open the window on Mars and put the talisman array was carefully calculated so that it would not appear. However, Yang Qing was not in a hurry.
