Chapter 409: Big Trouble After the Star Explosion
In order to recharge energy as quickly as possible, all the more than 10,000 underground cities on the entire Wandering Blue Star have fallen into energy-saving mode. Except for the important underground city life support systems, all other places that need electricity have stopped using electricity.

Even the electricity for cooking was cut off, and people had to rely on dry food instead. The reason for doing this was naturally to save electricity to supply the star destroyer machine guns.

In addition, the planetary engine has many backup hydrogen fusion generators, all of which have entered overclocking mode, striving to generate enough electricity in a short period of time to supply the star-destroying laser cannon.

Of course, not all planetary engines use energy to generate electricity, because the steering engines at the equator are still working.

That's right. After all, a star-destroying laser cannon must be not only powerful but also accurate. Even though the target, Blue Planet No. 2, has a diameter of more than 10,000 kilometers and looks very large, what if it is aimed at more than 20 astronomical units away!
You should know that the position of the wandering blue star at this time is equivalent to firing lasers at the sun at the position of Uranus in the solar system!

But don't forget that Blue Star No. 2 is revolving around its star system every moment, and it revolves around the sun at a speed of 30 kilometers per second.

Twenty AUs is equivalent to a distance of 3 billion kilometers, which means the laser has to fly for 10,000 seconds, which is equivalent to more than two hours.

This kind of shooting is more difficult than shooting a mosquito from three thousand meters with a Barrett, but fortunately, the laser does not have the parabola of a bullet, and the front light path is also very stable and will not be affected by wind.

In addition, there is a supercomputer called 550X, which is even more powerful than 550W, to assist in calculating the trajectory of the star-destroying laser cannon, so there is naturally no need to worry about missing the target.

That’s right, the 550X is the next generation of the quantum supercomputer 550W. Compared with the 550W, the 550X has a faster computing speed. Of course, the 550X is actually specially used to serve the star destroyer laser cannon and can be regarded as the ballistic computer of the star destroyer machine gun.

Of course, it was not that Liu Xiu did not want the Wandering Blue Star to fly closer before opening fire. The main reason was that the Wandering Blue Star could not withstand the gravitational force of large massive celestial bodies. If it got close to a large massive celestial body, it would inevitably cause plate movement on the Wandering Blue Star like the previous Jupiter crisis, thus causing a major earthquake on the Wandering Blue Star.

There was no other way. After all, there were more than 10,000 underground cities on Wandering Blue Star, with more than 6 billion people living there! Liu Xiu couldn't possibly ignore their safety.

Another advantage of this position is that it is far away from the stars, so the influence of the star's gravity is very weak. Therefore, by slightly deflecting the route, it can avoid the stress range of the sun and not be captured by the stress of the sun.

After three days of charging, the star destroyer laser cannon finally reached full capacity.

After Liu Xiu pressed the launch button on the console, a purple laser beam was emitted as Liu Xiu's finger pressed the button.

Of course, this is in the universe, not on a planet, so even though there is no atmospheric weakening, the laser beam will still diffuse due to the distance. Fortunately, the diffusion is not very large. A laser with a diameter of 100 kilometers only expands by about 50% after two hours when it lands on Blue Planet No. 2.

After all, the problem of long-distance diffusion was taken into consideration when the laser cannon was built.

Therefore, a 50 percent diffusion of a high-energy laser beam has little effect on the results.

After the laser attenuated a little after passing through the atmosphere of Blue Planet No. 2, the remaining light had already hit the surface, forming a large pit with a diameter of 150 kilometers.

But things are far from over. If the laser only creates a huge hole more than 100 kilometers in diameter on the surface, it would not be called a star-destroying laser cannon.

You should know that the reason why the star-destroying laser cannon tested before was able to blow up an asteroid with a diameter of 1,000 kilometers in one shot was not due to the power of the laser cannon itself. After all, according to common sense, the laser cannon can only make a hole with a diameter of 100 kilometers in the asteroid, but it is far from being able to directly blow up the asteroid.

The reason why the asteroid can be blown up is mainly due to the asteroid itself. That's right, the reason why the laser cannon looks so powerful is actually because it uses the tactic of using the asteroid's force to counter it.

This is just like blowing up the moon in the movie Blue Planet 2. Of course, you can't blow up the moon with just a few nuclear bombs, but what if you use the moon itself to blow up the moon!

That's right. The reason why nuclear bombs are arranged in a matrix and detonated in sequence is naturally to detonate the large amount of helium-3 on the moon. Use helium-3 to blow up the moon, that is, use the moon itself to blow up the moon.

This is just like the fact that hydrogen bombs are actually used as fuses in atomic bombs.

The same logic applies to using laser cannons to blow up stars. You should know that laser-ignited nuclear fusion has appeared as early as the 20th century. The powerful laser energy will heat objects to very high temperatures, and once these substances are instantly vaporized by the laser and have no way to escape, the next stage of nuclear fusion will naturally begin.

This does not make sense. After the laser beam from the laser cannon penetrates the surface, it continues to heat the rocks underground. The molten rock is heated and vaporized, but it cannot be dispersed due to the resistance of the surrounding matter. Therefore, the same fusion conditions as the planetary engine, high temperature and high pressure, are achieved, and then heavy nuclear fusion naturally begins.

One can imagine how many cubic meters of rock can be heated by a laser with a diameter of more than 100 kilometers. The energy that these rocks can release after nuclear fusion is naturally far greater than the energy required for the laser to ignite them.

Of course, these are not very important, because when the laser heats the surface rocks, the surface rocks can easily escape after vaporizing, but the heated rocks underground cannot disperse in a short time, so high pressure is naturally formed.

Therefore, high temperature and high pressure are naturally the two basic conditions for nuclear fusion. Nuclear fusion that occurs underground can either be suppressed easily or explode.

The consequence of this large-scale heavy nuclear fusion from underground is very simple, that is, the eggshell on the surface of Blue Planet No. 2 has finally been opened.

It looked a bit like heating eggs in a microwave, and then after the explosion, the entire microwave was filled with egg shells and egg remains.

The same is true for Blue Star No. 2, except that the explosion took place in space. Of course, both microwaves and lasers are, in theory, electromagnetic waves! It's just that the frequencies are slightly different.

But Liu Xiu’s happiness didn’t last long, the smile on his face froze in an instant, because a bigger trouble lay before him.

That is, when the egg explodes while being heated in the microwave, it is blocked by the microwave cabinet.

But we are in space now! There is nothing to stop the crustal debris after the explosion of Blue Planet No. 2!

And because of the explosion, these fragments scattered into the surrounding space at a very fast speed.

And at this speed, there is no doubt that the star's gravity will not be able to restrain it.
