The sealed Laboratory of Maxim the great undoubtedly brought enough impact to the Mars base.


    Despite the existence of shadow guards, they can not completely unseal this ancient laboratory that has been sealed for many years.


    However, some of the resources began to tilt here at Sun Cheng''s personal request.


    Sun Cheng personally sat here in the laboratory and stayed for more than half a month until the huge underground space was almost cleared. The Decepticons had a place to stay, and began to use it as a starting point to collect and try to explore more technologies in the ancient Cybertron civilization from the remains frozen for more than ten thousand years.


    Seeing that he was on track, he left the laboratory.


    As the most important fighting force of his own forces, sun Cheng can''t leave the earth for too long.


    But before leaving, there is another place on Mars, and he must make a tour.


    Sun Cheng first began to inspect the airport built somewhere in the Martian Grand Canyon.


    As the name suggests, an airport is a port for berthing spacecraft.


    This airport is located in a relatively flat area of the Grand Canyon, covering an area of about 70 square kilometers.


    Decepticon engineers have been smashing rocks and hardening the ground for a long time, and all the spacecraft that flew from earth to Mars are parked here.


    When sun Cheng arrived at the airport last time, he did not check it carefully.


    This time I came to inspect, but I really saw a lot of things.


    "Commander, the airport terminal has been planned and the command tower has been built. It can accommodate 12 Decepticon technical officers at the same time for spacecraft berthing and guidance!"


    "At present, four airport automatic air defense forts are planned to be built, of which the first has been completed, with a total of 96 sets of improved air defense systems in the database, which can launch 384 air defense missiles at the same time... The other three are also under construction and are expected to be completed in 73 days!"


    "In fact, we have considered directly equipping plasma air defense guns, but because the energy system has not been solved, we can only use relatively backward air defense systems for the time being."


    "However, considering that Mars is no better than the earth, our air defense system is not only equipped with a large number of high-precision ordinary missiles, but also adds the electromagnetic pulse bombs and small tactical nuclear bombs previously listed in the bases on the earth to the ammunition preparation of the venting system."


    Hearing this, sun Cheng nodded slightly.


    The Decepticons have already acquired the technology related to small tactical nuclear bombs.


    The source is still the polar bear.


    Like a far east country, polar bear has purchased a large number of advanced equipment and parts in its cooperation with them in the past few years.


    Just as polar bears have been wary of Decepticons, they have not only searched the world for the whereabouts of Decepticons, but even deployed several nuclear bombs at home, pointing directly at North devonsk 24 hours to prevent the worst from happening.


    Sun Cheng also ordered his Decepticons to spare no effort to install various secret doors in various equipment and parts sold to polar bears, and to search for all technologies of the former Soviet Union and even polar bears.


    In the eyes of all countries, a number of military technologies that should have been strictly guarded and prohibited from leakage have fallen into the hands of the Decepticons.


    Although the vast majority of them are not advanced in the Decepticons'' view, sun Cheng still ordered his Decepticons'' technicians to fully absorb them and upgrade them.


    There is no other reason. This is a complete scientific and technological system created by people on earth.


    Although there is no comparability in front of the Cybertron civilization with a bright history.


    But Cybertron civilization itself is now a joke. After countless years of civil war, Autobots and Decepticons beat their mother stars into death stars.


    The mobilization of a war has grown from millions at its peak to a scale of less than 10000 people.


    The death of countless cybernetics has lost a large number of cybernetic technologies.


    The science and technology system created by this civilization has already passively shaken its foundation and become riddled with holes and loopholes.


    Sun Cheng once tried to fill these loopholes and master the Cybertron civilization technology that once occupied most of the galaxy''s resources at that peak.


    However, he soon bumped into a bag and chose another way.


    Now sun Cheng is based on the scientific and technological system created by the earth civilization.


    Constantly use the Cybertron technology to improve and upgrade this seemingly childish civilization.


    The results are not rapid, but they are also making rapid progress.


    It seemed that sun Cheng was very interested in this. A Decepticon who was leading him to inspect the airport defense system ordered several engineers to pull over two small tactical nuclear bombs with a length of two meters under the escort of soldiers.


    "Commander, this small tactical nuclear bomb improved by us has an explosion equivalent of almost 800 tons of TNT..."


    Small tactical nuclear bombs and electromagnetic pulse bombs, as backup bombs for air defense systems, are weapons that can only be used when the situation is at an irreversible disadvantage.


    As for the target to be defended, except for the Decepticons on the moon, there is only the main force of the Decepticons led by the shockwave, which is almost reaching the solar system.


    After glancing at the small tactical nuclear bomb, sun Cheng nodded and went on.


    The Decepticons who guided him around the airport also continued to explain to him.


    "In terms of defense, at present, there is only one senior fighter in the airport leading a team of Decepticons... There are no aborigines on Mars, so it is enough for the time being!"


    "This airport is the largest parking space planned at present, and the ships that can be parked are million tons..."


    "We have received a complete exploration class cargo spacecraft from the central main control base, as well as the construction technology of Golden Eagle series spacecraft. At present, we are stepping up the construction of more spacecraft to facilitate mining in the asteroid belt!"


    The asteroid belt is a dense area of asteroids in the solar system between the orbits of Mars and Jupiter. Astronomers on earth say a lot about how it came into being.


    Decepticons don''t care how it came into being, but there are many mineral rich asteroids in the asteroid belt, and even a few asteroids all composed of metal or other resources.


    The size of Mars is there, and the resources on the planet are much worse than those on the earth.


    Perhaps a small part of resources, such as iron ore, may be richer than the earth, but the resources are far less complete than the earth and can not carry a civilization to upgrade to the aerospace era.


    Therefore, it is the right way to concentrate resources and forces, build cargo spacecraft first, then go to the asteroid belt for mining and feed back the Mars base.
