There was a cracking click on the frozen ground, and the snow and ice cracked open, revealing a strong light in the cracks, and the ice and snow that came into contact with the strong light slowly melted, and the melted water flowed down the open cave wall, and the water that fell to the ground flowed down the drainage pipe deeper into the ground, and it ended in the reservoir of the geothermal power station.

Soon the giant hole was completely opened, and then a large fluorescent lamp poked out of the giant hole, it looked to the ground, and then climbed out, and then climbed out of a lot of large fluorescent lamps one after another, these large fluorescent lamps were distributed in the position of about 100 meters of the giant hole, and when they arrived at the place, they automatically laid a few steel legs, so that they were fixed, and then the high-power lights of these large fluorescent lamps hit the ground, and all the nearby snow melted, forming a snow-free area of tens of thousands of square meters.

There are a large number of ordinary robots in the underground are busy, a launch vehicle is carrying out the final energy infusion work, and there are some necessary performance checks, after everything is ready, the ordinary robots are evacuated to a safe place, and after closing the gate of the previous part, the launch vehicle in the silo will be ignited immediately, and the tail flame of the launch vehicle engine will spew out towards the reserved hole, and after obtaining enough thrust, the launch vehicle will immediately fly out of the silo and run to the sky at high speed.

Launch vehicles have also been launched in other directions, and there is an increasing trend, yes, the mission of the launch vehicle was interrupted for 7 days, and before it was a drastic change in various disasters, so the mission was stopped, and now the disaster has stabilized, so the mission can be continued.

The function of the large fluorescent lamp is to increase the temperature on the ground, so as not to affect the normal launch of the launch vehicle in an ultra-low temperature environment, and after the successful launch of the launch vehicle, the low temperature will have little impact, after all, the nozzle temperature of the rocket engine is extremely high, and it will not be frozen by the low temperature environment at all.

Half an hour later, there was another launch vehicle ignition at the same hole, basically maintaining this frequency, a large number of frequent lift-offs of carrier rockets, and a large number of launch vehicles that completed the task fell back on the receiving platform, so that there were tens of thousands of rockets up and down, and the sky was very lively, which constituted the heterochromatic highlight of this frozen giant planet.

And the Saint Crystal powerhouses on other continents are still digging deep underground, and they have no chance to see this kind of scene, because they don't dare to go out at all, just because the outside environment is too cold, and they can't last long after going out, even if they find an abnormality, they can't travel long distances to the Moonlit Night Continent, it's too far away.

Through the delivery of materials by countless launch vehicles, the asteroid spacecraft in space is growing at a considerable speed with the naked eye, and it will take a lot of time to complete this behemoth, but these will continue to accelerate with the passage of time, just because this giant planet has been completely controlled by Tan Qiusheng, of course, its development will be faster and faster, and the more resources obtained, the construction speed of the asteroid spacecraft can be accelerated, which is a matter of course.

If you want to complete the manufacture of asteroid spacecraft within 10 years, you must increase the number of launch vehicles, tens of thousands, hundreds of thousands are too few, at least 10 million or more are needed, and it is a large-tonnage carrier rocket to meet this requirement, each large-tonnage carrier rocket is more than 10,000 tons, can transport about 1,000 tons of materials to space, it is not easy to achieve this efficiency, because this is a giant planet, its mass is very large, so it is much greater than the gravitational force on the earth.

There are also the limitations of the chemical fuel of the launch vehicle engine, which has been improved many times and has almost reached the limit, and if you want to have a better engine, you can only develop towards controlled nuclear fusion.

The first is the radiation-driven spacecraft of the working medium, which is driven by radiation pressure, has excellent endurance, can only sail in the vacuum of the universe, does not need to think too much about its own mass, can accelerate slowly, as long as the fuel is enough, then it can reach 15% of the speed of light.

The downside is that the thrust is a bit not large enough to make it impossible for them to land and lift off on planets.

The second is the working fluid propulsion spacecraft, it is possible to fly, but it is also facing the problem that its own mass is too large, the magnetic confinement nuclear fusion device is too large, so that the supporting engine will be amazingly large, you must know that the larger the engine, the more difficult it is to manufacture, and he must also be able to restrain the combustion state of the working fluid fuel, in this state any material will be dissolved and vaporized, if you want to restrain them, you can only use magnetic confinement, and magnetic confinement is a large device, controllable nuclear fusion requires magnetic confinement, The feed port of controllable nuclear fusion also needs a magnetic restraint device, and finally there is a magnetic restraint device with the engine feed port, two large and two small, and four sets of magnetic restraint devices are used here.

To maintain the normal operation of the magnetic restraint device, a large amount of power support is also required, that is, a large battery is required, this big guy may occupy 50% of the weight of the entire spacecraft, and it can only be used for a short time, and it will run out of power after dozens of minutes, which is just a round trip time for the launch vehicle, and then it needs to be charged on the ground.

There are also working fluid fuels and light element substances loaded on it that also need to occupy space, so that when calculated, it itself is very heavy, and whether it can fly or not is worrying, as for carrying materials to space, it is very difficult and not cost-effective.

The third is the dark matter propulsion spacecraft, in fact, it is an improved version of the working fluid propulsion spacecraft, which does not require working fluid fuel, and directly relies on the strong expansion principle produced by nuclear fusion as thrust, and nuclear fusion can produce nuclear fusion under ultra-high temperature and high pressure, nuclear fusion is the process of polymerization of light element matter into heavier element matter, which will make a small part of the strong force after the fusion of two atoms naturally overflow, and the overflow of the strong force is transformed into a weak force in the process, which is the process of super expansion, and the expansion will produce huge thrust and extremely high thermal radiation.

The binding space of strong and weak forces is dark matter, stars are in nuclear fusion all the time, and the overflow of dark matter is immeasurable, on the other hand, the speed of nuclear fission is much slower, which is why our universe will expand infinitely, but all this will have an end, that end is that all stars can no longer carry out nuclear fusion, the universe is full of heavy element matter, when the heavy elements in the universe in a large number of nuclear fission, the universe will enter the process of rapid contraction, such a general trend, All heavy elements are quickly broken down into hydrogen atoms, or lighter units. Eventually, it will coalesce into a ball of pure matter, and this ball will continue to collapse under the super power of the general trend, until the super strength cannot be compressed, and at this time, it will be reversed, and the ball will be infinitely compressed, and the ball will explode and the universe will be restarted.

The huge thrust + extremely high thermal radiation can make the working materials collide with each other, vaporize, burn, and expand to form a secondary chemical expansion thrust effect, but the secondary chemical expansion thrust is a bit redundant.

Instead of this, it is better to push directly with dark matter!

Using dark matter as a power source is to accelerate the aging of the universe, although Tan Qiusheng knows this, she still needs to do this, after all, she is too weak, this kind of thing that delays the aging of the universe, let's wait until she becomes the master of this universe!
