Chapter 415: Chapter 416 Extreme Cold Colonization
The cold wind is roaring. Accompanied by the cold wind is a large amount of snowflakes that are frozen by a large amount of carbon dioxide and methane. This is the outermost planet of the star system. Its volume is one-third of that of the star system. It is located on the Kuiper belt, about 40 astronomical units away from the star. It takes several hours of radiant to shine here. Planets.
Looking at the moving parent star from the surface of this planet is not much different from the bright stars in the sky. Darkness and cold are the themes here. The average temperature of the surface is constant at minus two hundred degrees, which is a cold hell that can really freeze steel.
After the protoplanetary disk gave birth to the star in the center, the remaining remnants that could not fall into the stars have gone through a long time. Because of the combination of each other's gravitational action, part of the material density of the inner ring is enough to form planets, and the outer part of the outer ring can only form a large number of meteorite groups due to be too widely distributed - the Kuiper belt. .
Therefore, it is very rare for planets to appear in such remote orbits. It may be a wandering planet captured by a star, or the density of local meteorites in the Kuiper belt is enough to form a planet. Over time, the planet's gravity will absorb the meteorite in the Kuiper belt into its own mass, thus weakening the bondage from the star. Every year, the distance between it and the star will increase by one centimeter. In the foreseeable future, it will get rid of this star system and become a wandering planet.
Now the future has changed. It has its belongers. A group of distant organic creatures spanning dozens of astronomical units from the direction of the star occupy the unmanned planet.
Due to the ultra-low temperature on the surface of the planet, their initial landing failed. A large number of organic seeds fell to the surface, and within a few seconds, they were solidified by extreme cold and entered eternal silence. During this period, the seeds will be quickly frozen by ultra-low temperatures of more than 200 degrees below zero, and smash them on the surface in a free fall state, and there is no possibility of survive.
However, if this is the only way to stop their race, the seeds send back the environmental information in the form of radio at the last moment before death. The kind of the closest to the outermost planet soon learned the situation and sent a group of mothership biota to carry a large amount of nuclear concentrated material to the outermost planet.
Their way is very rough.
The rhizome will extend all the way down to the underground stronghold on the opposite side of the planet. Without the high temperature of the core terror, the collectors can arbitrarily spread a network of rhizomes inside the planet, and then use the rhizomes, A large number of captured molecular substances are transported to the hive for processing, so as to obtain a large number of available materials.
Of course, although there is no terrible high temperature, ultra-low temperature still exists, which causes a lot of obstacles to the rhizome. Every time the rhizome goes deep, a reactor stronghold must be built to obtain heat, otherwise it will be frozen. Because of this, the expansion of the rhizome is many times more than the normal expansion time at night. .
In order to get more sufficient heat, it is obviously not enough to use fission reactors alone. Collectors began to follow the example of the Selin fusion reactor to bring more heat energy to the planet.
They chisel the edge layer of solid iron to make a shaft, inject a large amount of liquid water into the shaft, and finally put a hydrogen bomb into the liquid water for nuclear explosion until the whole water body warms up to 100 or more than 100 degrees.
Collectors will regularly measure the temperature of each shaft. When the water temperature of a shaft is less than 60 degrees, they will be put into a hydrogen bomb again to warm up.
Solid-state cores and high-density strata can fully withstand the vibration of nuclear explosions. The natural gravity generated by huge mass does not require collectors to create artificial gravity.
With the assistance of fusion reactors, the collectors expanded faster, and it didn't take long to complete the task entrusted to them by the highest will. In addition to the hidden and unmodified surface environment, the whole planet is densely covered with rhizomes from the ground to the core, and the temperature is constant above zero.
After that, they fell silent and were hidden as the cards of the ethnic group. Until a certain point in time, a piece of information from the ethnic group made them return to their previous activities.
"Have you understood the plan?"
"I understand." Then start to nurture and spread signal bodies.
"I understand."
