"Cybertron is a cube?"

Chen Xin was taken aback.

You must know that although the volume of a neutron star is only a dozen kilometers, its mass is comparable to that of the sun, with a density of one billion tons per cubic centimeter, which is 100 trillion times the density of water.

It is hard to imagine how this highly dense body can maintain the shape of a cube under strong gravitational pull.

Chen Xin shook his head, this kind of technology was beyond his imagination.

"Lao Dou, when we get out of the solar system in the future, we must find a neutron star to play with!"

There was a look of hope in the eyes of the steel hammer.

Chen Xin said: "Steel hammer, this time you must look inside the spaceship of the Karn civilization to see if there are any suitable materials for you to ascend to the third pole." ”

"Hmm!"

Gangyi nodded, and then his tone lowered again: "It would be nice if I hadn't lived in the past 90 million years. ”

Although the steel hammer had been promoted to a seventh-level civilization before, it was completely unable to sort out a complete technological system from level one to level seven.

The reason for this is the talent attribute of the King Kong clan itself.

Before the steel hammer level fell, it was basically looking for food all day long, and it dared to eat any material.

With the unique talent of the Vajra clan, it can parse any material that is one level higher than itself according to the material level.

But it is precisely because of this that it does not seek to understand the technology contained in those materials, coupled with the different ways of thinking between different civilizations, even if the seventh-level steel hammer is not as good as some low-level civilizations in terms of understanding the key technologies.

However, since two years ago, after establishing that kind of mysterious connection with Chen Xin, Gangyi has found that he is completely able to understand and accept the way of thinking of earthlings.

This is also the reason why it was more interested in music, painting, writing, and other activities that require emotional thinking, such as at the beginning of its awakening.

Later, with the gradual integration with the earth's civilization, the steel hammer can even understand the scientific and technological information on the earth, and even advances in some fields.

However, even so, the level of science and technology it has mastered is only the second-level high-level, unless it and Chen Xin spend twenty years to conduct hadron collision tests, or specially give it a key material of the three-pole civilization for it to digest and absorb, it is difficult for the steel tamper to break through the second level in a short period of time.

"Forget it, Steelhammer, don't think about it, let's go look on the spaceship first, maybe there will be an unexpected gain!"

"Hmm!"

The steel hammer immediately perked up, and his eyes lit up as he looked at the large spaceship a few kilometers away.

The two got on the lunar rover.

The lunar rover is a fully enclosed six-wheeled shape, eight meters long, 3.5 meters wide, and two meters high, like a small RV. It has a total weight of about fifteen tons, is fully electrically driven, has solar cells laid in the housing, and has an off-road speed of fifteen kilometers per hour. The car has a constant temperature and humidity, as well as a special living compartment and a material cabin, which is stored with drinking water and food, which can support half a month without any external support.

In a sense, the rover is a small base.

It took twenty minutes for Chen Xin to drive the lunar rover to the foot of the crater and stopped about a hundred meters away from the spacecraft.

From a closer distance, this spaceship was even more magnificent than Chen Xin had imagined.

It has a cylindrical shape, like a well-made cigar.

The surface of the ship was smooth and shiny, and the long years had not formed any traces on its surface.

"Huh, lithium-based strong interaction materials?!"

The steel hammer screamed.

Chen Xin was puzzled: "Steel hammer, what is called a lithium-based strong interaction force material?"

The strong interaction force Chen Xin knows that it is the force of protons and neutrons combining into atomic nuclei, and it is also the interaction force between quarks. Its size is orders of magnitude higher than that of the electromagnetic force, and because of this, it is able to overcome the strong repulsive force produced by the electromagnetic force and tightly bond the hadron into the nucleus.

However, this force is a short-range force, with a range of 10-15m, and once this distance is exceeded, the force will quickly disappear.

"This material is made possible by a special gravitational field that causes the strong interaction forces inside the helium atoms to escape, and the strong interaction between the nuclei of the atoms causes the vibrations of these atoms to tend to zero. However, such materials can only be manufactured by mastering the fourth-level civilization of the grand unified field theory, from hydrogen-based to carbon-based, a total of six grades, generally speaking, the fourth-level primary order can produce hydrogen-based strong interaction materials, the intermediate stage can manufacture helium-based, and the high-level can manufacture lithium-based, according to the periodic table, the fifth-level high-order civilization can produce carbon-based strong interaction materials. The Karn civilization had just been promoted to the fifth level, and it was completely understandable that their ships were made of lithium-based materials. The strength of this material is extremely high, the surface temperature is close to absolute zero, and if it is given speed, it can easily penetrate a planet like the Earth without losing a single hair of the material itself. ”

Chen Xin was taken aback and said, "Since this material is so powerful, how could this spaceship break into two?"

When the spaceship of the Karn civilization crashed into the moon, it broke into two parts, half of which was the part that Chen Xin saw, leaning on the outside of the crater, and the other half was inside the crater, which could not be seen for the time being.

"Maybe it's because of the power of space." ”

Chen Xin nodded thoughtfully, it seems that Mr. Karn did not lie to himself, when the Karn civilization came to the galaxy from the Great Magellanic Nebula, it was an accident in itself, according to the estimation of the steel hammer, the biggest possibility is that the other party encountered a space wormhole, so that this spacecraft can cross a distance of 160,000 light years at one time.

"Old Bean, this section should be the tail of the spaceship, and the energy cabin and material compartment of the spaceship should be in it. I'll go in first, and if it's safe to do so, you'll come in. ”

"Okay! Be careful. ”

Steelhammer nodded, and flew off the rover with a whoosh.

Chen Xin set the glasses of the spacesuit helmet to a projection mode, so that he could follow the perspective of the steel hammer at any time.

Instead of directly touching the surface of the spaceship, the steel hammer was transformed into a small drone, slowly flying to the top of the mountain to observe the ship's fractures.

The diameter of the ship's fracture is about two thousand meters, and it stands to reason that this fracture should be covered with destroyed cabins. However, after the steel hammer flew up, it was discovered that the fracture of the spaceship had been repaired by the Karn civilization at some point, and the surface was covered with a thin metal film, and it was basically impossible to see how much damage there was.

"Calorie deformation metal!"

The steel hammer screamed excitedly, and plunged headlong through the fracture of half of the ship. R1152
