At this time, after a period of planning and construction, the airport still appears very empty.


    At present, there are less than 100 spacecraft docked in the Martian airport. Most of them are armed transport ships and fighter ships of the Golden Eagle series, supplemented by a number of small cargo ships with hope level transformation.


    The only medium-sized cargo spaceship of the explorer was taken by sun Cheng when he transported goods from the earth this time.


    At present, with all the resources under his command, he has only built four such ships. It''s OK to leave one on Mars, but it needs to be used carefully.


    After staying at the airport for some time, sun Cheng went to the next destination.


    Before he leaves Mars, he needs to visit two places, the airport is only one, and the second is the arsenal.


    More accurately, it''s a battle robot factory.


    The robot factory on Mars is also located in the sailor Canyon, only 23 kilometers away from the Mars 1 base here. It is also built in a naturally formed cave found in the canyon.


    As the first factory built on Mars.


    At the beginning, only various engineering robots were produced here. Later, with the establishment of several other robot factories, the earliest factory carried out equipment upgrading under the command of sun Cheng to produce combat robots.


    And now he''s ready to receive the results.


    The Mars base seems to be greatly influenced by sun Cheng. The architectural style attaches great importance to concealment and practicability.


    Therefore, this battle robot factory is not so fancy.


    After entering a gate built on the canyon wall, there is a passage hundreds of meters long. There are three intercepting doors for isolating sand and dust.


    Further inside, there are three cave spaces arranged in parallel, of which the space in the middle has the largest area. This is the main workshop of the combat robot factory, with an area of about 30000 square meters.


    On the left is the metal processing workshop and on the right is the robot weapon production line. These two spaces are smaller, only seven or eight thousand square meters in size.


    Teams of robots move in and out of the battle robot factory, and six Decepticon engineers are enough to maintain and operate all the production equipment here.


    They continuously convert the minerals mined on Mars into various metals 24 hours a day, first into robot parts and weapons, and then assembled into combat robots.


    Then, all the battle robots were stacked in a huge warehouse directly connected to the cave space in the middle.


    Sun Cheng didn''t stay much in the battle robot factory. There are such factories and production lines in the central control base on earth, but they are not as large as this one on Mars.


    Directly under the guidance of the Decepticons in charge of managing here, go to the factory behind.


    The warehouse is very large. After all, it is necessary to place a large number of combat robots.


    Although the resources on Mars are far less abundant than those on earth, except for a few two or three kinds of raw materials used to make combat robots, the rest can be found here.


    Moreover, due to the large-scale use of robots for underground mining, the mining cost is lower than that of the earth.


    This is also the reason why Sun Cheng began to require a large number of combat robots on Mars.


    Although this thing can''t compare with Decepticons, it''s more comparable with the shadow guard of Maxim the great.


    But Sun Cheng can''t live without them for the time being!


    The atmosphere on the other side of the earth is getting more and more depressed. It is estimated that it can''t be suppressed for too long, and the war will break out.


    Decepticon army, car camp, earth local forces, and sun Cheng''s own forces.


    Among the four forces, he probably can only fight back and forth with the local forces on earth in conventional war.


    However, once the other side uses nuclear weapons, it will not only suffer losses, but also suffer a great loss with its only small tactical nuclear bombs.


    Of course, if sun Chengzhen conflicts with the earth''s native countries, he will take the initiative to attack before the other party has the sign of action, and paralyze the other party''s strategic nuclear counterattack capability as much as possible.


    But this still can''t get rid of an embarrassing fact. He and his forces are still not a heavyweight opponent compared with Decepticons and Autobots.


    However, compared with them, sun Cheng is not at all comparable.


    At least, his forces dare not say that they are concentric, but there is only one voice inside at present.


    Compared with the Decepticons, there are Megatron, shockwave, Starscream and many other factions within the Decepticons, and the power can''t be in one place at all.


    Even on the Autobots side, there are natural enemies, Optimus Prime, royalists, Democrats and all kinds of liberals.


    In my mind, some chaotic thoughts flashed and disappeared quickly.


    Sun Cheng looked at the warehouse full of combat robots. Two blue light columns shot out of his eyes. After quickly checking the status of all robots in the warehouse of thousands of square meters around, he immediately went to other directions.


    Not long later, he nodded with satisfaction as the status of the last batch of robots was checked.


    "The production plan is completed well. I''ll take these robots away!"


    Before setting out for Mars this time, sun Cheng considered that the war cloud on earth was already very heavy.


    He likes to plan for the worst in advance. In addition to sending some production lines and more Decepticons to Mars, he also stored most of the materials stored in the spherical space in his body in the warehouse on the Mars side.


    In addition, not long ago, it may be because he absorbed a lot of energy liquid, and the spherical space in sun Cheng''s body expanded a little.


    Therefore, it is not difficult to install this batch of combat robots.


    "It''s just all incorporated into my private Legion!"


    The private Legion is a project that sun Cheng started to prepare a long time ago. It uses the spherical space in his body to carry a large number of soldiers, which is put out immediately when the battle breaks out.


    In his plan, with a private legion, one can become an army.


    However, it is based on the most ideal state. If it is really implemented, it is not easy.


    First of all, although sun Cheng now doesn''t care about using spherical space to store and carry goods in front of his men, with his authority within his own forces, he uses the "space bridge" to describe this technology. Even if his Decepticons doubt it, no one dares to question it.


    However, the spherical space is his biggest card after all. The interior also involves the secret of crossing the two worlds. He is not at ease and can''t put any Decepticons in it, even if they seem very loyal to themselves.


    Therefore, the battle robot has become the only choice.


    "With those shadow guard corpses obtained in the experiment of Maxim the great, I believe that my group of Decepticons engineers will soon be able to develop some useful technologies to further upgrade the combat robots..."


    Only then can sun Cheng''s private army get rid of the fate of becoming battlefield cannon fodder.
