The return trip is shorter than the departure!


    The distance between the earth and Mars is not constant, because the speed and distance of the two planets around the sun led to the fact that the last time sun Cheng and his team went to Mars, Mars was almost farthest from the earth.


    However, with his stay on Mars for a month and the operation of the two planets again, the distance between the earth and Mars has been reduced a lot, so that his return journey can fly tens of millions of kilometers less.


    However, Rao is so. When he returned to earth again, it has been nearly two months since Sun Cheng set out for Mars.


    "Squeak!"


    With a burst of exhaust sound, the cabin door of the hope test spacecraft docked on the apron of a new spacecraft in the control area of base 2 slowly opened.


    Sun Chenggang stepped down from the spaceship and immediately saw almost all the Decepticon engineers in base 2, all concentrated near the apron and welcomed him back.


    "Master, welcome back!"


    He nodded. As soon as he got off the apron, two Decepticon engineers walked towards the spacecraft.


    One of them reached out to touch the hull and used the special ability of Decepticon engineers to check the current data of the test spacecraft more intuitively.


    The other entered the spaceship and picked up the log of the round trip with the central control brain of the spaceship.


    Seeing the separation of magic and the robot controlled by Explorer 203, sun Cheng nodded his chest, and a metal storage disk recording various Mars data was bounced out.


    "It records all the data taken on Mars, as well as the coordinates of the Mars base and the construction progress in the past month... You take it for analysis. I need a more detailed analysis of Mars and the Mars base in the shortest time..."


    Fantasy has a strong thirst for knowledge. Once sun Cheng even wanted to destroy him after discovering this.


    Sun Cheng admitted that he was indeed influenced by some human science fiction he had read in the past.


    In the fantasies of some human novelists and scientific and technological workers, high intelligent artificial intelligence with self thinking and logic, once born, will pose a threat to human security and survival.


    The self contradictory three principles of robotics clearly expose the fear and complex mood of human beings in the face of artificial intelligence.


    Sun Cheng was the same before, but with the regular full data inspection of fantasy, he has basically put down his vigilance against it.


    It seems that the people who created the magic Cybertron are silicon-based life with strong data processing ability. They fundamentally set a series of restrictions and logical frameworks for these super brains.


    Hearing his command, the magic controlled robot stepped forward and took over the metal hard disk from the bent sun Cheng.


    "Give me some time!" it replied, "please allow me to work now. I''m full of curiosity about Mars!"


    "Go!"


    With sun Cheng''s permission, the phantom robot left immediately.


    Explorer 203 is obviously also interested in the relevant data of Mars. After asking him for instructions, the robot split controlled by Explorer 203 also chased the phantom robot split and left together.


    Sun Cheng quickly noticed that there were two strange Decepticon engineers.


    After carefully distinguishing the electromagnetic spectrum emitted by them, he recognized it.


    "TOT and saihar, you two have been promoted to Decepticon Engineer..."


    TOT and saihar, members of the first batch of engineers cultivated by base 2, who were born a little later than Adam.


    At that time, sun Cheng also participated in the cultivation of many new Decepticons, and he still had some impressions of them.


    Atlas bowed slightly and explained to him, "master, Tott and saihar are another batch of Decepticon engineers who have just been promoted not long ago!"


    Sun Cheng nodded and looked at the two new engineers who were uneasy but perhaps excited to wait for his order.


    "Have you arranged some projects for them?"


    Atlas shook his head, "they helped in Hades''s team before, because they just finished the promotion two days ago, so we haven''t figured out the project we need to be responsible for yet!"


    Just listen to the name. The Decepticon engineer named Hades is naturally not a good stubble.


    Sun Cheng subconsciously looks at a guy who doesn''t seem to have much sense of the existence in front of the Decepticon engineer queue.


    "Hades..."


    His eyes stayed on the Decepticon Engineer for a while, and then he said, "Todd, saihar, you continue to stay in Hades''s research group and serve as deputy project leader. The rest dispersed first. Hades, Todd, saihar, you three stay!"


    Which of the Decepticon engineers in the line was not extremely smart, they immediately knew that sun Cheng had left the three engineers, and there must be major project arrangements.


    Suddenly, they looked at the three Decepticons one by one, all with envy and jealousy.


    Ignoring the two new engineers in the back who were dazzled by excitement, Hades bowed slightly, then stepped forward with a flattering smile on his face.


    "Master, I don''t know if those human politicians are still satisfied with the previous medical cabin?"


    This Hades is the Decepticon engineer who flattered sun Cheng and built the medical cabin for him.


    The Decepticon engineer team under sun Cheng has begun to expand so far.


    However, at first, the more than 20 Decepticon engineers really played a great role in his expansion.


    Almost every Decepticon engineer undertakes the research of several major projects and topics at the same time, but Hades is an exception.


    Every Decepticon is unique, so although they can quickly master certain knowledge and adapt to a new project with strong computing power and learning ability.


    However, influenced by their personalities and hobbies, even if all Decepticon engineers have the same starting line, they will gradually decide among different classifications.


    This Hades is a Decepticon engineer who is very interested in carbon based life and dedicated to studying it.


    Engineers spend most of their time in base 2, engaged in various research, and rarely deal with humans.


    But Hades is an exception. He has a good relationship with Yuri.


    At first, because Yuri needed some white flour to disturb the chaos in South America, sun Cheng asked atlas to arrange a Decepticon engineer to make it for him.


    It was during several cooperation with Yuri that Hades met and seemed to have become a good friend.


    Over the next year, Yuri got a lot of new things from Hades.


    Similarly, when sun Cheng opened and closed his eyes, Hades asked Yuri to get many heinous prisoners from the chaotic prisons in South America for his research work.


    The medical cabin he presented to sun Cheng was the product of Hades'' research.
