After making an appointment with Optimus Prime, sun Cheng didn''t stay much with the forerunner and left soon.


    He doesn''t know whether the natural enemy has been awakened, so it''s dangerous to stay more rashly.


    The king of PU, who is extremely hostile to Decepticons, has the fighting power of even shaking the sky.


    During the civil war in Cybertron, he once suppressed several Decepticons by personal force for a long time. He was called the strongest existence under the 13th Yuanzu by the automobile. Obviously, sun Cheng can''t deal with it now.


    As for how much Optimus Prime believed, he didn''t care.


    Sun Cheng did not expect Optimus Prime to fully believe in himself. On the one hand, he was his former teacher and on the other hand, he was a Decepticon traitor.


    However, as long as he began to have doubts in his heart, it was enough to avoid that Optimus Prime would not respond at all when his natural enemies made trouble in the future.


    Instead of directly returning to trindadi Island, sun Cheng separated from the pioneer over the South Atlantic.


    The pioneers who already have the combat power of elite soldiers will continue to be stationed on trindadi island.


    He has had enough experience before, so sun Cheng believes that the pioneers can be competent in the subsequent reconstruction of trindadi Island, or in the management and protection of the black market.


    As for himself, he returned directly to base 2.


    Before the invasion of the black market, sun Cheng realized that the earth was no longer safe and that base 2 might have been exposed.


    This idea was undoubtedly more firm after Starscream''s legion of replica soldiers invaded trindadi island.


    The sense of crisis from breaking the door has made sun Cheng decide to increase the Mars base.


    He will go to Mars again. This time, he will not only transport a large number of materials, but also prepare to transport a group of Decepticon engineers, technical officers and engineers through spherical space after they all sleep.


    After coming up with this idea, sun Cheng informed base 2 in advance and asked them to start screening people who volunteered to go to Mars.


    The environment and conditions there are undoubtedly much worse than the No. 2 base that has been formed now.


    Engineers and technical officers are in a relatively low position, and sun Cheng doesn''t care much about their attitude. Basically, the base arranges the list. He is going to send 200 engineers, technical officers and 50 Decepticons to Mars at once.


    However, Decepticon engineers and senior engineers, he still wants to give face to these subordinates who have followed him for several years.


    At first, sun Cheng would ask them to recommend themselves or each other to Mars according to their wishes.


    He gave ten lists. Only when his Decepticon engineers and senior engineers were dissatisfied with self recommendation, they would personally select and supplement them.


    We have been informed in advance before. When sun Cheng returns to base 2, everything is ready.


    "Master, everything has been selected according to your requirements, from personnel to materials. Hope has also completed the detection and energy replenishment."


    Nodding, sun Cheng ordered directly, "let them start to gather and sleep!"


    He connected with the central master brain of base 2, and immediately found that on the list provided by "magic", there were none of the Decepticons senior projects sent to the Mars base this time. Only two of the ordinary engineers were old people who followed him for more than a year, and the rest were all new Decepticons engineers who had just been promoted in batch not long ago.


    Sun Cheng is not disappointed with this list.


    Decepticons, like humans, have all kinds of desires and greed.


    At present, the situation on Mars is full of unknowns. Because of the relationship just established by the new base, all kinds of materials and conditions are worse than those on earth.


    Although Decepticons can survive in the universe for a long time and stay in various harsh environments, it does not mean that they like to stay on Mars with thin atmosphere and frequent harsh environments.


    "I hope you don''t regret it in the future!"


    The knowledge of new Decepticon engineers is not much worse than that of some old Decepticons. There is a big gap between experience and small skills of private research.


    Therefore, sun Cheng was not dissatisfied that only two older Decepticons were willing to go to Mars.


    However, in the future, the main person in charge of the Mars base will certainly give priority to the previous batches of Decepticons sent to build the Mars base.


    Moreover, once the earth side is really going to be in chaos, the safety of base 2 in the future can not be compared with that of Mars.


    Sun Cheng also knows that in the future, there will be self righteous Decepticon engineers under his command, who will be annoyed by today''s choice.


    The trading time agreed with Optimus Prime is one month later.


    It takes time to prepare materials and equipment, and it also takes time for the Autobots to extract energy from the [leadership module].


    Therefore, sun Cheng decided to take advantage of this time to go to Mars.


    With his order, base 2 was immediately busy.


    Voluntarily, there are Decepticon engineers, engineers and technicians selected by the base, and dozens of Decepticon soldiers, all of whom fall into a dormant state with the help of doctors.


    Spherical space is sun Cheng''s biggest secret. He has done experiments in private before. He can put live animals and live micro Decepticons in it.


    This discovery made him both happy and worried, but since then, sun Cheng has been more careful.


    Even if he has to put the Skyfire and other Decepticons into the goal space, he needs to ensure that the other party is in a dormant state before putting them into the goal space temporarily.


    In the huge warehouse, rows of containers with different specifications ranging from three to five meters in height are neatly stacked in the warehouse.


    Sun Cheng quickly put these containers into the spherical space one by one. This time on his trip to Mars, he will stay alone in the spacecraft.


    After returning from the last experimental fire exploration trip, hope''s Decepticon engineers once again carried out a series of maintenance and transformation on the spacecraft according to various data collected during the trip.


    The current hope is faster than before, and its stability and performance have been improved.


    After entering the cockpit and sitting down, sun Cheng immediately communicated with the pseudo brain on the spacecraft.


    "Hope, start the optical stealth device... Target Mars... The accurate coordinates have been entered, ready to go..."


    "Command accepted, power system on... Optical stealth device on..."


    After opening the optical stealth device, the hope experimental spacecraft seemed to be shrouded in a water wave.


    Although the four cooling plumes from the engine cannot be completely covered, optical stealth devices can more or less cover most observation equipment on earth.


    Soon, the spacecraft took off from a launch site in base 2 along the long calculated flight orbit, escaped the earth''s gravity at a very fast speed and began to fly in the direction of Mars.


    Sun Cheng also began his second trip to Mars.
