The second line of defense consists of five satellites of Tianyuan B, hundreds of thousands of concealed mines and controlled batteries hidden in the asteroid belt.

Xiao Yu no longer expected the attack weapons on the second line of defense to be able to inflict even a little scratch damage on this water droplet, as long as these weapons could hold this water drop for two hours, Xiao Yu would be satisfied.

Within these two hours, Xiao Yu will manipulate the robot to cut the Huantianyuan Four Large Particle Collider apart, use one end as the muzzle, and manipulate the orbital adjuster installed on it, so that it can aim at the water droplet. Then, at the other end, a proton will be fired, and after more than 200 million kilometers of acceleration, the proton will shoot out of the muzzle of the cannon and hit the water droplet at a speed close to the speed of light.

This is Xiao Yu's whole jihua. Theoretically, this jihua is completely feasible. Because this proton, which is traveling at nearly the speed of light, will explode at the moment of impact, within a unit area, the energy level far exceeds that of the energy cannon, and this will destroy the strong force shell of the water droplet, causing it to shatter like glass.

The droplets have completely destroyed the first line of defense and are rushing towards the second line of defense, which is expected to be close to the second line in thirty minutes.

At the collider, Xiao Yu was already manipulating a spaceship, carrying 10,000 robots to carry out an intense transformation project. These robots will first cut the collider pipe, then install a large shield at the muzzle to prevent any unrelated particles from entering the pipe, and then repair its damaged wiring, Zuihou, will install a power system directly controlled by Xiao Yu on the pipe, so that Xiao Yu can easily change the aiming direction for it.

At that time, the entire four large particle colliders around the Tianyuan will be turned into a giant cannon with a length of more than 200 million kilometers!

In the midst of the intense work of the robot, time slipped away bit by bit. The water droplets have crossed the long distance of hundreds of millions of kilometers and come to the second line of defense.

The first to greet the water droplets were the five thousand combat spaceships arranged in the Tianyuan B interstellar fortress, among which there were nearly a hundred county-level spaceships, and among the five satellites of Tianyuan B, a total of eighteen giant energy cannons were arranged.

One hundred county-level spaceships led five thousand village-level and township-level spacecraft, launching a torrent of high-velocity bullets at the same moment, and in the midst of the torrent of bullets, thousands of interstellar missiles were also carried with them.

As soon as the two sides met, they immediately started fighting, without any superfluous movements.

The attack power of these 5,000 ships will be able to crush a civilization twice as strong as the lizardman civilization, but when faced with this water droplet, these ships are as fragile as plastic toys in the hands of babies.

Xiao Yu saw with some gloom that a county-level spaceship was approached by this water droplet with a frenzy of bullets, and the spaceship that had no time to escape was instantly penetrated by this water droplet, and the nuclear fusion reactor instantly went out of control, and the violent energy burst out, blowing the spaceship into pieces.

But the energy frenzy of the ship's destruction also washed the water droplet out of a distance of hundreds of kilometers. This water droplet tumbled all the way, directly crashing into three other village-level spaceships.

In the battlefield, the light of hydrogen bomb explosions flashed out continuously, and each hydrogen bomb explosion would burst out with hundreds of millions of degrees of high temperature, vaporizing all matter except water droplets within a radius of at least a few hundred meters, but under such a high-density attack, this water droplet still did not suffer any damage.

Its shell is still very smooth and clean, without a single scratch. It still has a 100 percent emissivity, reflecting the distant starlight in the universe and the light of the hydrogen bomb explosion in the near distance.

Xiao Yu couldn't care about the distress and fear. The five thousand ships here, as well as the five satellites in the starfortress, as well as the hidden artillery batteries hidden in the asteroid belt, have already exerted 100% attack power. They, with their own deaths, are trying their best to delay the progress of the droplets.

Behind them are 10,000 robots at work. Forty minutes have passed, the cutting has been completed, and the robot is installing a shield for the collider's muzzle. After the installation of the shielding device, the power system will be installed, and then a high-power laser cannon will be installed to clear the track.

The huge space fleet composed of 5,000 spaceships has been destroyed, half of the spaceships have been destroyed, and there are still 36 of the 100 county-level spaceships. Five war fortress satellites, already one, have completely destroyed the weapons system.

Hundreds of millions of bullets continue to hit the water droplets, each bullet contributing its own kinetic energy before being bounced away. Xiao Yu is using this method of ants biting elephants to death, trying his best to delay time.

However, there are too many ants to bite an elephant, and no amount of bullets can destroy this droplet.

The battle was extremely fierce.

In this kind of technological asymmetrical war, Xiao Yu's huge computing power has no effect. Computing power is at the same level as the basic theory, and only the jishu gap can play a role in the war. In the war with the water droplet, no matter how good Xiao Yu's calculation power is, no matter how efficient the attack method is, and he can exert a thousand percent attack power, in front of the water drop, he is still slaughtered.

The drops are still alive and well. It can always fly back quickly again after the passive weapon is turned on, and its speed is never reduced by the torrent of bullets and the explosion of the hydrogen bomb, even if it is temporarily reduced, it will instantly increase again.

Moreover, it seems to be able to control the trajectory in which it is ejected, and after being bounced off by impact, it will always take the opportunity to crash into several village-level ships that have not had time to dodge.

Xiao Yu's current total number of spaceships is 20,000 village-level spaceships, 5,000 township-level spaceships, 400 county-level spaceships, and four city-level spaceships. This is all the accumulation of Xiao Yu over the past few hundred years, and now, more than 100 county-level spaceships have been lost, and more than 8,000 township-level spaceships and village-level spaceships have been lost.

This is equivalent to a quarter of Xiao Yu's combat power, which is equivalent to Xiao Yu's accumulation of hundreds of years, and it has become nothing.

Moreover, there is no doubt that if Xiao Yu does not have a way, at most one day later, Xiao Yu's fleet will be completely wiped out, and Xiao Yu will also die.

The only hope is to see if the four large particle colliders around the Tianyuan can work.

The modification of the collider has been carried out to the stage of installing a laser cannon. It is known that the laser cannon is ineffective against water droplets, but Xiao Yu needs to rely on the laser cannon to clear a clean track for the protons to fly.

You must know that protons are killed by impact, and there is a large amount of matter in the Tianyuan four galaxies, if the orbit is not empty, if the protons hit other substances, it will be wasted.

It takes at least twenty minutes to launch a proton. The acceleration process takes 15 minutes and the preparation time takes up 5 minutes. This means that Xiao Yu only has two chances at most. After two times, the water drops did not die, and it was Xiao Yu who died.

This is a big gamble of life and death, if you win, Xiao Yu will continue to have the future, and if you lose, Xiao Yu will be removed from the universe, and human civilization will be removed from the universe.

In the second line of defense, more than four thousand ships of five thousand ships have been destroyed. Of the five combat satellites, three have lost their attack power. These thousand ships are no longer able to organize an attack on the scale of the beginning. The killing speed of the water droplets also increased. It is estimated that the second line of defense will be able to hold back the water droplets for another twenty minutes.

Here in the collider, the laser cannon has been installed, and Xiao Yu is directing the robot to install the power system. With the power system, Xiao Yu can adjust the aiming direction of the muzzle, so that he can aim at the water droplets and fire protons.

This process takes at least 40 minutes.

"Hurry up, hurry up." Xiao Yu muttered silently in his heart, a little anxious.

Time passed bit by bit, and the battlefield was already full of the wreckage of the spaceship. All kinds of broken copper and iron are floating in the battlefield, and those who have reached the third cosmic speed have already flown out of the Tianyuan four star system without hesitation, not knowing where they will fly in the end, and those who have not reached the third cosmic speed will orbit around Tianyuan four.

The water droplet rushed towards Tianyuan B, its speed accelerated to 5,000 kilometers per second, and under the strong kinetic energy and power, the water droplet directly penetrated the sixth satellite of Tianyuan B, turning the sixth satellite directly into a world of earthquakes and volcanoes. The weapons systems laid out on it, all destroyed.

The entire second line of defense has become a tomb at this moment, and the water droplets, like terrifying zombies crawling out of the grave, rushed towards the interior of the galaxy with death.

Between the four large particle colliders and the water droplets, only half of the defense line was left. That is, the asteroid belt.

However, most of the weapons that Xiao Yu arranged in the asteroid belt were for surprise attacks and sabotage, and in Xiao Yu's planning, he did not consider such a situation as facing water droplets at all.

The asteroid belt, which is expected to last for twenty minutes. After breaking through the asteroid belt, this water droplet will reach the collider in 30 minutes. At that time, it only needs a slight impact to destroy the collider at will, and the Huantianyuan 4 large particle collider with a length of 200 million kilometers will be completely paralyzed.

Twenty minutes passed, and the water droplets broke out of the asteroid belt. This time, it did not choose to destroy all the weapons hidden in the asteroid belt, because the entire asteroid belt is hundreds of millions of kilometers long, and it will take too long to empty it completely. Instead, it cleared a section of 100,000 kilometers long. The rest of the place couldn't attack it, and it didn't bother to pay attention.

Thirty minutes away, it's about to reach the collider. And here at the collider, the installation of the power system has also been carried out to the zuihou stage.
