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.
These mothership creatures landed directly on the planet in a free fall. The huge volume of the earth with terrible momentum crashed into a huge crater with a diameter of tens of thousands of kilometers. These mothership creatures completely put their lives and death aside and paved the way to conquer the planet with their own bodies.
While the temperature has not yet dissipated, a large number of collectors rely on biological nuclear reactors to dig the strata under the biological corpses of the mother ship, establish underground space, and transfer a large amount of materials to the ground. The ultra-low temperature on the surface will soon recover, and the light of the star is too weak. Such a scale is almost equivalent to starlight. How much energy can be obtained by starlight? Photocosis loses its utility in this case.
Before the surface temperature recovered, the collectors had completed the transfer of materials, established a planetary stronghold under the surface, and began to build around the stronghold.
They are familiar with the low-temperature environment. Even if the environment here is lower than the original surface environment, it is only a difference in temperature. The essence is still the same. If you want to expand and colonize in this environment, you need a heat source, and then a large number of heat sources are laid based on the heat source. When such a heat source is laid. The whole planet, the colonization of that planet is also completed.
Under the ground, the collectors assume that the rhizome lay a large number of lightweight, loose and porous organic fiber materials on the outer wall, so as to establish a heat insulation layer, keep the heat as much as possible, and block the low temperature as much as possible.
Then it is based on this to obtain the material of the planet, process and use it, and then import the production sequence to make the snowballs roll bigger and bigger.
Radio-communication creatures are conceived. It has a long metal antenna extending from the ground to the surface.
Standing in the fierce cold wind, communicating with the collection strongholds of the major underground voids. In this way, the underground colonization of the collectors will be much smoother.In close strongholds, collectors will give priority to expanding in the direction of the same-ethnic strongholds, converge with each other, and then continue to expand in the direction of farther-at-field strongholds. In this way, a global underground network will soon be completed. The next thing to do is to make the net more dense and occupy those that have not yet been excavated. That's it.
After completing the global underground occupation, these collectors will not stop here, because this can only be regarded as the preliminary completion of their colonial operations. The area occupied is only a stratum that wraps the whole planet at a certain distance from the surface, which does not make a separate control and utilization of the resources of the planet.
Therefore, after laying the complete ball under the ground, a large number of rhizomes begin to invade and expand towards the planetary core to occupy more resource areas.
The core of the planet has been completely cooled down for a long time. What remains in the core is only a mass of extremely dense solid iron. Such an environment also allows collectors to make local changes to their expansion plans.
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."
