Outer space, geosynchronous orbit.


    It''s dark here. Ordinary people can''t tell the direction without the help of tools.


    In other words, the word direction doesn''t mean much to ordinary people in outer space.


    Above the blue planet, a huge artificial celestial body, maintaining the rotation speed of the earth, floats quietly in a synchronous orbit.


    Space Fortress.


    At present, honeycomb laboratory is not only the largest giant structure project, but also its highest technical crystallization.


    The whole space fortress is composed of two rings, one large and one small. The two rings are connected like a crown on the head of the earth.


    Inside the ring, there is a pipe type living area. There are seven kilometers at the widest place and six kilometers at the narrowest place.


    The diameter of the entire outer ring is up to 160 kilometers, which is preset to provide more than two million people to live in.


    The smaller ring is the core area of the whole space fortress.


    The most important intelligent unmanned factory, star ship maintenance Institute, various large laboratories and spaceport for berthing star ships have been set up here. Sixteen huge nuclear reactors are also built on this smaller ring space.


    It can be said that this small ring is the core of the whole space fortress.


    From the design point of view, there is no direct connection channel between the outer ring and the inner ring.


    If you want to get from the outer ring space to the inner ring, you can only take the discovery. Of course, in the future, there will only be more and more star ships in the pasar islands.


    In fact, on the island of Anlu, the second meteorite class starship is already under construction.


    Even according to the idea of honeycomb laboratory, in order to save transportation costs, the construction of star ships in the future is likely to be moved to the space fortress.


    After all, with controlled nuclear fusion and anti gravity technology, outer space mining has become easier and easier.


    In the future, the demand for ore in pasar islands is likely to change from foreign transportation and import to outer space mining.


    After all, compared with the world and the earth, this boundless universe is the biggest treasure.


    Of course, at present, the outer construction of the Space Fortress has only been completed. The construction of the inner space of the ring has not been carried out. In other words, it is impossible to live for the time being.


    To make this space fortress fully operational, we must at least solve the artificial ecological circulation system inside the ring space, that is, the biosphere.


    This solution has been given by the honeycomb biology laboratory.


    Next, just follow the steps step by step.


    Anyway, in a short time, this circular space will not be inhabited.


    It can be said that this space fortress has exhausted all the accumulation of Fang Cheng in the alien world in the past year, and the biggest consumption is the demon aversion metal.


    After all, the main material for making the Space Fortress - class a armor alloy, you need to use demon averse metal.


    Crescent City in the whole continent, or through trading, or through their own mining, finally got enough of the magic hating metal they needed, but it also made Fang Cheng run out of all his inventory.


    In the final analysis, it is the limitation of resources.


    After all, with controllable nuclear fusion technology, energy is no longer a constraint for the other party. The only constraint is resources.


    The resources here include mineral resources, rare metal resources and so on.


    This also proves once again the prospect of space mining.


    After all, the resources on the earth are limited. Even if the competition for foreign resources is relatively small, it is not unlimited.


    But only in outer space, as long as you have technology and means, the resources you can obtain are almost unlimited.


    Without the constraints of resources and energy, no one can imagine how much potential the Pasa islands, which has mastered advanced artificial intelligence, can burst out.


    This magnificent Space Fortress in front of us is a clear proof.


    Although the interior of the space fortress is not completely completed, the external construction alone is an engineering miracle.


    In other countries, even those with the strongest industrial capacity, it will take decades to build such a huge structural project on the ground.


    What about the honeycomb lab?


    According to the chief engineer of the aerospace research center, it took two months and 14 days.


    Admittedly, this time is not the preparatory work, but the installation and construction time in space.


    Even so, the speed is too fast.


    But if someone watched the whole construction process of the Space Fortress, they wouldn''t feel that the time is fast.


    In order to build this space fortress, Fang Cheng''s intelligent unmanned factory has produced a total of 760000 C-2 engineering robots.


    What is the concept of 760000 C-2 engineering robots.


    In terms of labor conversion, the labor efficiency of a C-2 engineering robot is equivalent to that of 100 ordinary people using tools, which is still on the earth.


    In outer space, with the work efficiency of an ordinary person wearing a bulky spacesuit, the C-2 engineering robot has to throw it a thousand times.


    Even with such high work efficiency, the whole pasar islands has done almost everything to build this space fortress.


    The whole intelligent unmanned factory in pasar islands, even the intelligent unmanned factory in other lands, is serving the space fortress.


    If Fang Cheng does not have the whole alien world as the resource heritage, if not, the honeycomb laboratory has mastered the controllable nuclear fusion technology.


    The miracle of man-made celestial bodies like Space Fortress cannot be completed at all.


    This moment.


    Standing in the Aerospace Command Center, Fang Cheng was even more shocked.


    This will be the first and most important step for mankind to step out of the earth.


    Thinking of this, Fang Cheng could not help clenching his fist.


    "Commander in chief!"


    At this moment, the chief engineer of the Space Center changed the name of Cheng and whispered, "the nuclear reactor can be activated."


    Fang Cheng slowly took back his eyes, took a deep breath, turned his head and said, "let''s start."


    "Yes, commander in chief!" He nodded and ordered, "ready to activate the reactor!"


    As soon as the words fell, Yunmeng''s voice sounded in the whole command center.


    "Nuclear reactor activation countdown."


    Right above the holographic projection, a red countdown appeared in front of the crowd.


    Fang Cheng took a look, and the countdown showed "59:59:58". Below is a line of rapidly beating numbers, which are milliseconds.


    One hour countdown.


    Compared with this epic project, this countdown is very short.


    The reason why the countdown is so short is that all the early tests and preparations are perfect.


    Now all Yunmeng has to do is quickly simulate one side to ensure that everything is safe.


    After all, for the sake of this space fortress, the pasar islands can be described as "breaking bones and muscles". If the activation of the nuclear reactor fails, we will lose face and postpone the Mars colonization plan of the honeycomb laboratory.


    And this time is not short. After all, almost all the resources accumulated in such a long time have been consumed by the big guy in front of us.
