During the flight of Satellite No. 43, the bombing of Planet No. 1 never stopped.

The human fleet bombed indiscriminately and used all kinds of tricks. Energy cannons, laser beams, interstellar missiles, interstellar mines, and especially the most important hydrogen bomb, have never stopped.

The planet's landscape has even been completely changed. Mountains were flattened and canyons filled. The large crater formed by the hydrogen bomb explosion kept appearing, disappearing again and again amidst the fierce attacks, then reappearing, disappearing again, and so on.

There are less than 40 lava beasts left hiding underground and refusing to come out.

If it were an enemy of intelligent life, it should be easy to detect the abnormality of human beings at this moment.

After all, it’s strange that we know that we can’t hurt us hiding deep underground, but we still attack with such intensity and intensity for such a long time.

It's obvious that humans have some conspiracy.

But lava beasts are not intelligent life.

Although they have fighting skills, in the final analysis they just rely on instinct.

They only know that hiding underground is safe, but the surface is dangerous when being bombarded by enemies. They will be killed once they reach the surface.

So you must hide well. As long as you hide, you won't be killed. Wait until the human attack stops before going out.

Time passed slowly like this, and 3 years passed in the blink of an eye.

At this moment, the speed of satellite No. 43 relative to planet No. 1 has been accelerated to 102 kilometers per second.

Under the gaze of the huge dark red star, the small Planet 1 is passing through perihelion and has even entered its outer atmosphere.

If someone stood on Planet No. 1, what would appear in his eyes would be an indescribably huge sun.

This sun will occupy three-quarters of the entire celestial sphere, covering almost the entire sky. If one ignores the dazzling light, the person standing on Planet 1 can even clearly see the surging plasma on the surface of the YT-621 sun.

A star at the end of its life is extremely large. Its diameter is more than 30 million kilometers, but its outer atmosphere can even extend to twice that distance.

At perihelion, the planet rotates at its fastest speed.

At this moment, its speed relative to the star reached 65 kilometers per second.

The extremely high speed causes severe friction with the star's outer atmosphere.

No matter how thin the stellar atmosphere is at this distance, the friction caused by the excessive speed causes the surface temperature of the planet to rise to more than one thousand degrees Celsius.

This is the side facing away from the star. On the side facing the star, the temperature is even higher.

If Planet 1 had an atmosphere, the situation would be better. After all, it would not be in direct contact with the stellar gas.

But unfortunately, in the round after round of orbits, the atmosphere of Planet 1 has long been stripped away, and no residue is left, so the planet's surface can only be in direct contact with the star's atmosphere. Rubbed.

In this friction, the huge momentum of Planet No. 1 was consumed bit by bit. When the momentum is dissipated, the planet will fall a little toward the star. In the process, the planet's gravitational potential energy will be converted into kinetic energy, accelerating its speed and preventing it from falling further.

Then, the kinetic energy is dissipated again, and the gravitational potential energy is converted into kinetic energy again...and so on.

Until it exceeds a certain critical point, the gravitational potential energy can no longer provide it with more kinetic energy, and it will plunge into the stellar gas and completely merge with the star.

But it took too long, even more than 1000 million years.

People decided to move this time forward.

The way to advance is satellite 43.

At this moment, it is only less than 1 million kilometers away from Planet .

When orbiting Planet No. 4, it originally had a speed of about 8.5 kilometers per second. As it continues to approach the star, the gravitational potential energy is converted into kinetic energy, increasing its speed by about 16 kilometers per second.

The work of more than 30 planetary thrusters for several years has provided it with a speed of about 22.5 kilometers per second.

In total, its speed at this moment reaches about 47 kilometers per second.

Moreover, due to the triple influence of star gravity, planetary gravity, and planetary thrusters, its speed is still further accelerating.

It heads straight towards Planet 1, moving forward inexorably.

At this moment, the violent bombing of the surface of Planet 1 is still in progress.

Bearing the harsh environment around the red giant star, enduring the light, heat, and high-temperature and high-radiation gases that are constantly spewing out from the star, the human fleet still dares not relax at all times.

The plan is now in its final stage and must not fall short.

Planet 1 is accelerating. Satellite 43 is also speeding up.

Finally, just 20 hours later, a long distance of 1000 million kilometers was spanned by two planets heading in both directions. Then, at a slightly tilted angle, Satellite No. 43 slammed into Planet No. 1. At this moment, the speed of Planet 1 relative to the star is 70 kilometers per second. The speed of satellite No. 43 is 58 kilometers per second.

At low speeds, the total velocities can be added directly without taking into account relativistic effects. Eliminating the angle problem, the relative speed of the two planets reaches an astonishing 125 kilometers per second.

The human fleet had evacuated early and witnessed this shocking collision in a safe place.

At this moment, Satellite No. 1, which was only one-sixtieth of the size of Planet No. 160, almost completely penetrated into Planet No. 43. At the edge of the collision, endless rocks were splashed out, and even broke away from the gravity of planets and stars, and began to fly into interstellar space.

The entire Planet No. 1 shook violently at this moment. Countless peaks created by hydrogen bombs were flattened, countless canyons were closed, and countless new canyons emerged.

Behind the impact point, a mountain peak hundreds of kilometers high suddenly emerged.

The entire planet is turned upside down.

Through simple calculations, people can know that in this impact, a full 1.5*10^32 joules of energy was released.

This number is so huge that it has escaped people’s intuitive understanding.

The total energy of solar radiation received by the earth every second is approximately 1.74*10^17 Joules.

This energy drives the movement of the atmosphere on the earth, forming wind, rain, thunder and lightning, heating the oceans, allowing them to remain liquid, evaporating water, forming rain and snow, providing warmth for all things, and nurturing the flourishing of life.

The energy released by this impact is equivalent to 8.62*10^14 times this number.

In other words, if the energy released by this impact is converted into the solar energy received by the earth, this energy is enough to illuminate the earth for about 2730 million years.

The solar energy received by the earth is approximately equivalent to 22/ billion of the total radiant energy of the sun.

In this conversion, the energy released by this impact is approximately equivalent to the entire energy released by the sun in 4.5 days.

All the energy that the earth received from the sun in 2730 million years, or all the energy that the sun radiated in 4.5 days, was instantly released in this impact.

Planet No. 1, which had been continuously rubbed by the red giant's outer atmosphere and thus continuously lowered its orbital altitude, was suddenly hit by such a violent impact at this moment and received such a violent burst of energy that the entire planet's orbit was significantly affected. Impact.

It is still orbiting the red giant star, but compared to its previous orbit, its orbit at this moment has dropped significantly, showing an obvious arc.

It loses more speed. As a result, the laws of physics force it to lower its orbital altitude more to make up for the loss in speed.

But...the closer you get to this red giant star and the deeper you go into its atmosphere, the higher the density of material in its atmosphere.

The higher the density of the material, the more intense the friction with the planet. The more severe the friction, the faster its kinetic energy is lost, and the orbital height is further reduced.

Further reduction in orbital altitude further increases the rate of kinetic energy loss.

This is a vicious cycle that is irreversible once started.

The faster it falls toward the star, the faster it falls.

In just three days, Planet No. 1 was swallowed up by the huge red giant star and was no longer visible from the outside world.

This journey originally took more than 1000 million years to complete, but with the participation of humans, it was completed in just three days.

It fell into the stars forever. Falling in with it were nearly 40 powerful lava beasts hidden deep beneath the surface, still waiting for the enemy to stop attacking.

People clearly knew that although the previous impact was violent, it was not enough to kill all the lava beasts hiding under the surface of the planet.

But it doesn't matter, after falling into the star, this aging and violent star will kill every lava beast on behalf of humans.

It is impossible for any lava beast to survive among the stars. Even if the survivability of the lava beast is increased tenfold, it is impossible.

The fate waiting for them will be to be torn apart together with Planet 1 after crossing the Roche limit, and then be completely swallowed.

——Faced with some stars with extremely low density, the Roche limit can even enter the interior of the star. Obviously, this red giant star is such a star. Therefore, even if it is swallowed up, Planet No. 1 will not be torn into pieces, but only after it goes deeper.

The fall of Planet 1 triggered a more violent reaction from the red giant star, making it even more violent.

More stellar matter was ejected, and the galaxy environment became more hostile.

But it doesn't matter, the human fleet has already been hiding in a safe place.

After watching the entire process of the planet impact, Lu Xinghe knew that the human side had truly completed this mission.

Although there are still a few fish that have slipped through the net and are hidden in the galaxy, they can no longer make waves.

Their only fate is to be searched out and destroyed by human fleets. (End of chapter)
