Luo Yuan opened the curvature bubble and flew slowly through the galaxy.
Ignoring the wandering planet on the periphery, this star system is undoubtedly much smaller than the solar system. The four planets, large and small, slowly revolve around the star according to their own orbits.
Based on the distance from the star, Luo Yuan labeled these four planets as No. 1, No. 2, No. 3 and No. 4.
Among them, numbers 1 and 4 are solid planets, and numbers 2 and 3 are gas planets.
The largest of them is gaseous planet No. 3, with a diameter comparable to that of Saturn. It has an earth satellite system composed of five satellites. With Luo Yuan's vision, he can clearly see the endless wind blowing inside its atmosphere, and the whole world is It was lightning and thunder.
The smallest planet is Planet No. 1, which is about more than 4,000 kilometers in diameter, only one circle larger than the moon and only one-third of the earth. Because the light is dim and the temperature in space is extremely low, even if the planet orbits close to the star, it is still covered with a thick layer of ice and the surface is smooth, making it difficult to see the undulations of the terrain.
Luo Yuan's target is the outermost planet No. 4. The earth is already the largest solid planet in the solar system, but Luo Yuan discovered that this planet is one and a half times larger than the diameter of the earth. It is a veritable giant solid planet. planet.
It can be seen from the gravitational field it emits that its mass is quite large.
This is a quite positive signal for Luo Yuan, which shows that this planet is basically a rocky planet, and its interior is filled with a large amount of heavy elements. It is a perfect resource planet for humans.
In fact, within the scale of the universe, the stock of heavy elements is limited and rare.
The reason for this is because the nuclear fusion of stars usually starts with hydrogen or helium and ends with iron. If the internal pressure of the star is not high enough, it will end when it reaches carbon and oxygen. To finally fuse into iron, the mass of the star needs to be at least eight Above the mass of the sun, the highest possible sequence of zinc elements has been formed by fusion.
Most of the heavy elements in the universe come from supernova explosions. When a giant star violently collapses, it can produce terrifying high temperatures of hundreds of millions of degrees Celsius in the "severe pain" of its final death. It is "baked" by the energy of this dying explosion. "Under this, elements beyond iron and zinc are formed. As for superheavy elements such as gold, platinum and radioactive heavy elements, they come from collisions between neutron stars and the regurgitation of black hole matter.
Luo Yuan guessed that extreme celestial objects such as neutron stars once existed in this star field including the solar system. It was their death and dissipation that made this star field full of heavy elements.
…
It didn't take long for him to fly near the planet, and then like a meteor, he quickly fell towards the surface of the planet.
Although this giant planet has a huge gravitational force, it does not have an atmosphere. After all, no matter what kind of gas, it solidifies at this low temperature close to absolute zero, but it has to be compared with who else. Compared with the near-vacuum space outside, here still has a meager atmospheric concentration.
As Luo Yuan followed the gravitational pull of the planet, his speed became faster and faster. His body began to gradually burn under the friction of trace gases in the atmosphere. What started as an imperceptible red light turned into a raging ball in the blink of an eye. The fireball eventually turned into a dazzling light.
On this originally dead planet, strong winds gradually appeared, and countless air currents vaporized on the surface of the ice, blowing like smoke and fog in all directions.
When approaching the surface, Luo Yuan's speed had reached a quarter of the speed of light. The huge kinetic energy he carried had not had time to collide, and the ice layer with a radius of hundreds of kilometers had begun to dent inward, forming a huge bowl shape.
"boom!"
A dazzling light, like a nuclear bomb explosion, lit up from the surface.
The several-kilometer-thick ice layer at the center of the explosion was instantly broken down into microscopic particles. Even more than a hundred kilometers away from the periphery of the explosion, the ice layer was illuminated by this light that was hundreds of times brighter than the surface of the sun. It quickly vaporized, and then was radiated in all directions by the shock wave that followed.
If you stand at a high altitude, you can clearly see that this area was hit by the impact, forming a huge basin with a radius of several hundred kilometers. On the earth, the area is equivalent to half of Jiangnan Province.
The energy generated by this impact was not comparable to the casual blow from the last time I tested my strength.
The mass of Luo Yuan itself has reached more than 100 tons, plus the more than 200 tons of the space ball, the total mass is close to 400 tons. The energy carried by the impact at a quarter of the speed of light is no longer comparable to that of the one dropped in the reconstruction area. Anti-matter bombs are much lower.
Luo Yuan was floating quietly at the bottom of the pit with an expressionless face. Under this level of impact, his body was still unscathed. The ice layer was not a substance with a collapse ratio of 50,000. To him, it was no different than passing through the air. There is no essential difference.
At this time, he had penetrated directly through the ice and penetrated deep into the rock layer. His surroundings were still filled with dazzling light. No matter could exist at such high temperatures, and all matter was broken down into basic atoms.
"Gravity 3.5G, magnetic field strength: 0.001T; twenty times that of the Earth... Fe: 51.5%, C: 13%, H: 8%, O: 3%"
He quickly analyzed the surrounding environment. This planet is quite rich in iron elements. At least in this area, iron elements account for 50% of the element types. On the earth, this is undoubtedly a rich iron mine with water resources. Light elements are also abundant enough to serve as fusion fuel.
He waved his hand, and the water vapor that had accumulated like mountains around him was separated by his wave. The next moment, his whole body soared into the sky.
Hundreds of seconds later, he was back in space.
He took out the space ball and opened the space channel. After a while, a mini spaceship the size of a sesame seed flew out slowly along the space channel.
During the flight, it began to expand rapidly at a speed visible to the naked eye. One second, it was only the size of a sesame seed. The next second, it had become the size of a round table. After more than ten seconds, it had turned into a giant…
…
A year and a half later.
The dead and desolate Barnard star system gradually became noisy.
On the surface of Planet 4, with the basin formed after the Luoyuan impact as the center, a huge mining and metallurgical base is like a steel forest, covering the entire basin, and even spreading to the periphery for hundreds of kilometers, with tens of Thousands of huge mechanical arms are filled with endless power, constantly going deep into the ground, absorbing the rich minerals in the ground.
In the synchronous orbit of the planet, a huge metal space city covering an area of tens of thousands of square kilometers is also in full swing and extremely busy.
A large number of mining spaceships are like busy ants, shuttling back and forth between the space city and the planet, transporting various crude elements, which are then further processed and smelted here to manufacture various mechanical equipment.
The productivity that has been suppressed for a long time due to resource constraints is simply terrifying once it breaks out.
With a large amount of technology stored in the virtual world being quickly transformed into real results, tens of thousands of factories have been established here in the past year and a half, and they are still being built and expanded.
In one of the giant factories covering an area of thousands of square kilometers, two huge gantry towers stand tall in orbit like mountains, and the construction project of a new spacecraft has officially started.
