Although Xiao Yu has no way of knowing the production method of this material, Xiao Yu can know the strength of this material through observation and calculation.

That is within Xiao Yu's theoretical system, there is no way to destroy this material. theoretical system, and different from practical application. If it can't be found in the theoretical system, it means that Xiao Yu's science and technology, even if it develops for another thousand years, 10,000 years, as long as there is no breakthrough in the basic physical theory, Xiao Yu will not be able to destroy it.

"Could it be, this time, is it really going to die?" Xiao Yu thought sadly.

The killing of Xiao Yu's spaceship by water droplets continues. Thirty minutes later, Xiao Yu's fleet stationed at Tianyuan C, a total of more than 4,000 spaceships, was completely wiped out.

Here, there are only countless wrecks left in space, floating around the Heavenly Garden. Occasionally, flashes of light, tiny explosions, etc., erupt from the wreckage. Xiao Yu knew that it was sent by the parts that had not been destroyed by all the circuits.

The water droplet, still intact, still has a 100% albedo, and an appearance that is not stained with a little dust or a little scar.

It rushed towards Celestial Garden C.

In the Tianyuan C planetary system, Xiao Yu arranged weapon systems on a total of three satellites. Together, these three satellites form Xiao Yu's first line of defense.

"Destroying a building on the ground is not much more complicated than destroying a spaceship or destroying a building on the ground, what does it want to do?"

Seeing the water droplets move like this, Xiao Yu had a little doubt in his heart.

But the next moment, Xiao Yu's doubts turned into shock.

Since the arrival of this water droplet, it has given Xiao Yu countless shocks, but Xiao Yu can guarantee that this shock is definitely the most shocking.

Two of the three satellites have atmospheres. This means that the flight of the aircraft on the surface of the satellite will be seriously hindered. However, Xiao Yu saw that after the water droplet flew into the surface of the satellite, it did not produce any heat during the friction process with the atmosphere.

"How so? How so? Friction generates heat, this is common sense, I don't believe it, it can violate the most basic laws of physics! Xiao Yu thought with shock, "The only explanation is that after the heat energy is generated, it is immediately neutralized by its own low temperature, so it does not show the basic characteristics of frictional heat generation on the outside." ”

"But, but, what does that mean! This means that its surface temperature is infinitely close to absolute zero, and it has a system that maintains a low temperature beyond my imagination. ”

Absolute zero, about minus 273.15 degrees, is the lowest temperature in all physical theories. Because the temperature of a substance depends on the motion of the molecules and atoms that make up the substance, and at absolute zero, the molecules and atoms have stopped moving, so it is impossible to have a lower temperature than absolute zero in the existing theoretical system.

However, in the high-temperature movement of the high-speed rush into the atmosphere, the water droplet does not show any characteristics of high temperature, which means that ...... This water drop has an energy supply system beyond Xiao Yu's imagination. This basically shattered Xiao Yu's idea of using up the other party's energy and then destroying it.

This water drop has already brought Xiao Yu too much shock. For the first time, Xiao Yu sensed the deep sense of powerlessness brought about by the technological gap.

The water droplet passed through the atmosphere, and then it slammed straight into an energy cannon that Xiao Yu had placed on top of the satellite.

The energy cannon was destroyed instantly, and then, after destroying the energy cannon, the moment the water droplet touched the ground, it suddenly stopped moving, and then immediately flew high and flew towards the other side of the satellite, and after three seconds, destroyed the other energy cannon.

"I'm on a satellite base, and I have a more advanced observation system! Before it destroys the first line of defense, I must parse out its basic physics! ”

Xiao Yu made up his mind that before he completely destroyed the first line of defense, he must analyze whether this water drop was built from materials constructed by strong interaction forces.

The observation instruments of the first satellite were in operation for only thirty-two seconds before they were destroyed by this water droplet.

Subsequently, the water droplet left this satellite and flew towards another satellite. This time, the water droplet went directly through the surface of the satellite, crossed the satellite, and flew out from the other side of the satellite.

This satellite, completely penetrated by water droplets.

The strong kinetic energy directly caused the geological activity of this satellite to fall into an extremely unstable state, and on this satellite, an extremely serious earthquake and volcanic activity occurred, so Xiao Yu arranged all the weapons on this satellite...... All destroyed!

But before all the instruments on this satellite were destroyed, Xiao Yu's observation instruments operated for another sixty-seven seconds!

The third satellite of the first line of defense met the same fate.

This time, Xiao Yu's observation instrument ran for a full 136 seconds.

Xiao Yu just watched this water drop wantonly exert his almost miraculous ability, and the shadow of despair in his heart became thicker and thicker.

At this point, the first line of defense, along with the more than 4,000 ships, was completely destroyed.

"By consuming its energy, let it fall into a state of powerlessness, abandoned." Xiao Yu silently came to a conclusion.

The reason is very simple, if the other party does not have an adequate energy supply, it is impossible to make this kind of behavior that is similar to wasting energy in Xiao Yu's opinion.

That...... What is it for?

"It's teasing me?" Xiao Yu pondered, "Is it deliberately making me frightened and despairing?" However, does a roving space detector have this kind of thinking that is close to that of intelligent creatures? Does that mean...... Is it actually directly manipulated by some intelligent being? ”

"I already know that mechanical civilization is not welcome in the universe, so what is the reason why a civilization that has mastered super technology does not directly destroy me, but teases me?"

"One possibility is to vent anger, and the other possibility is to have a whim. These two speculations account for 90 percent of the possibilities, of which the possibility of venting anger accounts for 60 percent of the possibilities. ”

Xiao Yu analyzed silently and came to a conclusion in his heart.

This speculation is of great reference significance for Xiao Yu to deduce the social structure of the so-called Guardian Alliance.

"Let's put that aside for now." Xiao Yu thought, "If you can't solve the current crisis, even if you completely grasp the social structure of the other party, what's the point?" ”

At this time, this water drop had already left the first line of defense and rushed towards the second line of defense with Tianyuan B as the core.

Xiao Yu also came to a conclusion through the observation instruments arranged on the first line of defense.

"It'...... It's really built with strong interaction forces...... Why, how can such a perverted material exist? Well, I've got a way to destroy it. ”

Xiao Yu came to this conclusion with despair. Because, the method of destroying this water droplet only exists in Xiao Yu's physical theory system, and it is not known how many years it will take to realize it.

That's ...... Through the ultra-high energy level, it instantly breaks its atomic dense state. Even if it is just to break the fixed state of one atom. As soon as the fixed state of one atom is broken, the strong interacting material that makes up this water droplet will occur, and a chain reaction will occur, and the entire detector will be completely destroyed.

It's like a piece of glass, if one thing is damaged, the whole piece of glass will shatter.

The material that makes up the water droplets is somewhat similar to the matter of neutron stars, but it is only similar. Compared to neutron star matter, it is many grades worse.

By breaking the fixed state of one atom of it, the entire water droplet can be destroyed.

But...... Even the hundreds of millions of degrees of high temperature of the explosion of a large-yield hydrogen bomb can't do this, and ten energy weapons can't do it in a salvo, what other way can Xiao Yu have?

The droplets rushed towards the second line of defense at an extremely high speed. Twenty minutes later, the second line of defense is expected.

And within the second line of defense, there are the four large particle colliders around the Tianyuan.

"Wait...... Wait a minute! I've figured it out! The moment he remembered the four large particle colliders in the Huantianyuan, Xiao Yu was full of cleverness. Because, Xiao Yu thought of a way that might destroy this water droplet.

As long as one atom can destroy a water droplet, its entire outer shell material will undergo a chain reaction and be completely disintegrated.

And destroying even one atom of it would require an extremely high level of energy. It is known that the unit energy level of the large-yield hydrogen bomb is insufficient. The unit energy level of the energy cannon is also insufficient.

The energy level is not enough, which means that Xiao Yu cannot destroy even one atom of the other party.

But...... The Huantianyuan Four Large Particle Collider can reach such an energy level! You can reach the energy level of destroying one atom of the opponent!

You must know that at the moment when the two protons collided, the energy level of the Huantianyuan Four Large Particle Collider could even reach the level of one femtosecond after the Big Bang!

If such an energy level is not enough, Xiao Yu can't imagine what other substances in the universe can be reached. It can be said that within a unit area like a proton, the energy level that can be achieved by the Huantianyuan Four Large Particle Colliders is not inferior to that of a neutron star collision!

"It's a viable option!" After planning this plan, Xiao Yu immediately became excited.

"It's worth a try! It's just that I still have a lot of preparation to do before testing. ”

"The second line of defense, all ships, space-based batteries, land-based batteries, covert batteries, controlled mines, all activated! Do everything you can to keep it out of the second line of defense. The collider must not be destroyed! Huantianyuan four large particle colliders, start! Get ready! ”
