Because the connection with spherical space becomes weak, for fear that consuming too much energy again will endanger your return to the real world.


    Sun Cheng did not dare to continue to use the spherical space to carry this batch of transported metals. He had to spend a full day successively and transported back dozens of tons of precious metals from Russia, including several rare metals or a large number of precious metals needed by the base.


    As for the rest, he will then arrange to take the freight route into Brazil, although it will be about a week late, at least saving him a lot of time.


    It has been four or five days since I left base 2. Back here again, atlas has finally completed the manufacturing of the nuclear reactor they have prepared for more than a month!


    "... crazy, keep an eye on the noise..."


    After finishing everything, I learned from magic that atlas has completed the nuclear reactor and is undergoing commissioning.


    Sun Cheng immediately gave frantic a communication and ordered him to keep an eye on the noise and not let the guy who had never really surrendered himself take the opportunity to make trouble.


    He himself left the underground karst cave and walked to a construction site that was in progress more than ten kilometers away from the base.


    Before people arrived, sun Cheng saw atlas coming face to face. It was obvious that he had known in advance that he came.


    In this regard, sun Cheng''s eyes swept around the industrial robots busy carrying building materials, but he didn''t say much.


    "Master, you are back!"


    Sun Cheng nodded and looked beyond the corner where he floated to the valley. The faintly visible buildings smiled a little more on his face.


    "... how''s the nuclear reactor going?" he asked, looking at atlas.


    "Very smooth!"


    Atlas replied excitedly: "at present, the main construction of No. 1 nuclear reactor has been completed, and the underground condensate tower is under construction. We are commissioning the reactor, and it is expected that the first test will be carried out in 17 hours..."


    Sun Cheng has seen atlas''s design drawings before. In the future, three thermonuclear power stations will be built continuously within hundreds of kilometers around base 2, and only one set of nuclear reactor will be placed in each thermonuclear power station.


    Don''t underestimate Cybertron''s technology because there are too few reactors!


    On the contrary, because thermonuclear power generation technology is more mature than human nuclear power technology, atlas''s nuclear reactors are not only much smaller than human beings, but also much more efficient.


    Take the No. 1 nuclear reactor under construction, which is the thermal nuclear reactor closest to the underground karst cave where No. 2 base is located. Strictly speaking, it is a political project.


    Because sun Cheng gave the order, Atlas could only build the nuclear reactor in the shortest time.


    Therefore, No. 1 nuclear reactor will be the least efficient of the three thermonuclear reactors, and only a 450000 kW pressurized water reactor unit will operate.


    However, Rao is so. With Cybertron''s mature thermonuclear power generation technology, it is even less than one seventh of the scale of area 1 of basangela nuclear power plant.


    In particular, the common eye-catching cooling tower in the power station has been transformed into an underground condensate tower, which greatly reduces the probability of exposure.


    Although operating a set of hot water cooling device will increase a lot of operating costs, for sun Cheng''s mechanical life, energy is the most precious thing, and everything else has to stand aside.


    On the construction site, dozens of industrial robots kept moving and dragging in and out.


    Sun Cheng looked closer and was more satisfied. He couldn''t stop nodding, "the speed is good..."


    Seeing that most of the moving places were shockproof materials, he pondered for a moment and immediately reacted.


    Different from the factors that people focus on building nuclear reactors on the seaside, sun Cheng''s mechanical life will not be affected by drinking water. Moreover, Cybertron''s thermonuclear technology is much more mature than the current nuclear power generation technology on earth, so it naturally saves a lot of trouble in construction. Therefore, the most important consideration is not water source, pollution and site selection, It''s shockproof.


    Although most parts of Brazil are not at the plate boundary, they are not vulnerable to earthquakes.


    However, there are still some dangers in the amanbai mountain area. Since the engineers started the construction of No. 2 base, the earthquake monitoring equipment has recorded a magnitude 2.0 earthquake. Although the focal point is deep, the magnitude is small and the impact is small, the necessary earthquake prevention means are still indispensable for the construction of nuclear reactors here.


    "After the commissioning of the thermonuclear reactor is completed, go and prepare for the manufacture of my new body. After the manufacture of my new body is completed, I will manufacture a new body for you!"


    "Yes, master!"


    Led by Atlas, sun Cheng walked around the construction site. Sun Cheng also saw some robots that looked different from ordinary industrial robots. He asked curiously, "Atlas, these are your newly designed robots?"


    "It''s not a new design, it''s just some simple modifications. Although the industrial robots we originally manufactured can cope with most of the work, some work is more precise, and some strengthen the load... So we modified several robots to meet different needs..."


    Sun Cheng nodded and looked at the robots for a while, but his eyes were thoughtful.


    Before that, he was always curious about the difference between [ignition source] and why it can transform some mechanical equipment into mechanical life.


    His doubt was answered by Megatron.


    In some memory fragments read by sun Cheng, he has found the answer.


    [ignition source] was once the property of the Decepticon army. From Megatron to shockwave to Starscream, almost all Decepticon executives and scientists have contacted it and tried to study it.


    From Megatron''s memory data, although sun Cheng was disappointed to find that he did not find information about the source of [ignition source], the Decepticons obviously had a deep research on it.


    Because [core] this magical thing is the product of the scientists of Decepticons such as concussion wave and Starscream, who study the special fluctuation of [ignition source], and then adjust the energy wavelength.


    "Simulate the energy wavelength of [ignition source]..."


    Sun Cheng murmured that although he didn''t have a [fire source], he had several pieces of [fire source] on his hand.


    He and Magic have done experiments on this before, and it has been basically proved that the fragments of [ignition source] can quickly recover the special fluctuations contained in it that can transform the machine into mechanical life by absorbing energy.


    Then he immediately told atlas, "last time, I asked you to build a small reactor in my laboratory according to the shipboard nuclear reactor I left behind. How did you do?"


    "The nuclear reactor has been manufactured according to your requirements, master. However, we have surveyed your laboratory and it is not suitable to place the nuclear reactor. However, we have made a survey in the base and it is more suitable to place it in the warehouse..."


    "Warehouse?"


    Sun Cheng just pondered for a moment, then nodded and agreed: "OK, the space is large enough. You can send someone to fix it as soon as possible, and I''ll use it immediately..."


    Previously, in the Mariana Trench, he scanned Megatron''s body and got a more detailed information, which is very beneficial to the final revision of his new body.


    However, it takes a lot of energy to make a new body for ourselves, so we can''t start construction until the No. 1 thermonuclear reactor is put into use.


    This will take some time!


    It is obvious that he is not going to waste this time. It is very appropriate to study the fragments of [ignition source] again!


    ps：


    My iron friend has known me since junior high school. It has been fifteen or six years now. He got married on the 9th. It''s customary for me to help on the 7th. There will be no accident on the 8th and 9th. I will be too busy to find the North these two days. If I give a notice in advance these two days, it may be interrupted for two days.
