It took some time to explain the tasks of the next stage and the things that need to be busy.


    After sending everyone off and busy, sun Cheng quietly walked around the base, feeling very deeply.


    "The change is quite big!"


    Sun Cheng had to stay in Russia for several months because Starscream found him doing wind and rain in North devonsk. He had not returned to base 2 for some time.


    Back here again, he wandered around the familiar and a little strange base. His mood is really a little complicated.


    Base 2 has been changing. Although there are only a few pieces of [ignition source], Atlas is still not fast in cultivating new Decepticons. The real mechanical life under sun Cheng, including the newly cultivated Decepticons, is barely more than a hundred, and most of them are the lowest Decepticons engineers.


    However, the slow cultivation of mechanical life does not mean that the manufacturing speed of robots is also slow.


    The existence of Decepticons and Autobots always makes sun Chengru''s back. He is like the politicians in the White House and Capitol Hill. He never feels a little secure.


    Under the influence of this uneasy psychology, base 2 is on war alert almost all the time. All production lines and workshops are running at full capacity. Facing the solution of raw materials and energy problems, more production lines and workshops are constantly put into use.


    Almost every minute, various types of industrial robots will be manufactured in the base.


    The battle robots produced for war have been designed to the third generation. Only from the original design and data, they are reliable products that can fight cannon fodder Decepticons such as noise, hammer and boomerang for a period of time, although the cost is just as high.


    The scale of all types of robots under the control of base 2 has exceeded 10000. Under the abundant labor force, the change of [underground caves] where the main body of base 2 is located is still small, and the spatial change of underground buildings is not too large, which is only less than 30% higher than that when he left last time.


    A large number of alloy pillars and explosion-proof metal plates are fixed in cement and permanently integrated into the mountain. In the future, it will not be said that they were attacked by ground penetrating missiles, that is, the magnitude 9 earthquake once in a century, which is difficult to affect the base.


    Compared with the "underground cave", which has not changed much, Decepticon engineers command robots in an area covering nearly 9000 square kilometers, transform a large number of mountains and valleys, and deploy hundreds of air defense missiles and combat robots in the inaccessible mountains and valleys in the west of the Brazilian plateau, It forms a security barrier for Gongwei base.


    Dozens of factories, hydropower stations and even semi underground nuclear power plants have been built and put into use.


    Although they have been promoted to engineers, the 20 or so Decepticon engineers under sun Cheng were originally Decepticon engineers trained to build permanent steel fortresses and war fortresses. In their bones, they have a fanatical love for the war fortress that has long been branded in the deepest memory.


    If sun Cheng didn''t want to expose the existence of the base in a short time, I''m afraid when he comes back this time, he will see a large-scale steel fortress in the inaccessible mountains of the western Brazilian plateau in South America.


    Speaking of it, he ordered the forerunners to build base 2 and the surrounding defense system.


    Although the latter was completed by atlas under the supervision of frenzy, the main skeleton was built in the pioneer period.


    In this area of nearly 10000 square kilometers, 256 sets of s-300pmu air defense missile launching systems have been deployed in the air defense system alone.


    According to Russian standards, a battalion is usually converted by four launch units and 16 launch systems. 16 air defense missile battalions have been deployed around base 2.


    Don''t think this quantity is very small. On the contrary, when sun Cheng said he wanted to buy the S-300 with Lao maozi, although they were happy to export this backward air defense missile in exchange for more advanced alien technology, they wanted to wait until Russian military enterprises produced new goods for seven months at the earliest, and then fully met all his requirements, I''m afraid we can''t do it in five or six years.


    But Sun Cheng wants it in a hurry!


    Finally, after several consultations, he offered the price for the new goods, and maozi transferred a batch of old money from the Russian military equipment in active service that had been in service for more than three years to him.


    Rao is so, but he just scraped together the equipment of four air defense missile battalions.


    The reason why there are so many bases here is self-evident.


    After receiving his order, Atlas had to transfer a group of engineers and engineers to transform two production lines for the production and transformation of S-300 series air defense missiles.


    In fact, they have not made major changes. First, although the S-300 series is not the most advanced on earth, it is enough to deal with most fighters and missiles.


    Second, it is powerful enough to hurt the flying units of Decepticons and Autobots.


    Therefore, under the concept of output first, engineers just added a set of automatic control systems. The significance of their existence is to ensure that the base will not have the ability to protect itself when it is hit from the sky.


    Of course, it is not his style to only defend but not have the ability to counterattack.


    In fact, sun Cheng has been seeking to obtain a decisive strategic weapon, such as medium and long-range ballistic missiles and even nuclear warheads.


    Unfortunately, the two countries he has contacted, whether maozi or the red regime in the Far East, are very firm in this regard. Even if he wants to buy some conventional warhead matching, he has always been very cautious.


    They had no choice but to produce by themselves.


    Sun Cheng used some unsavory means to steal some sealed data of maozi''s ss-21, which is commonly known as the beetle''s short-range ballistic missile.


    The world''s old maozi once signed a China missile treaty with the Americans to abolish their martial arts during the former Soviet Union. After that, although there are still some technical reservations, Russia''s technical waste on medium - and short-range missiles is much more serious than expected.


    Three months ago, with a thorough understanding of the relevant technology, the first beetle missile had been manufactured. Up to now, the base has stored more than 50.


    This short-range tactical missile, which has been improved by engineers and has doubled its range to more than 250 kilometers, although it is still equipped with ordinary warheads, it is enough to hurt leaders like Megatron and Optimus Prime. It is one of the good cards in his hands.
