When I finally returned to the No. 2 base in Brazil, it was half a month since I left last time.


    Let Hephaestus and others continue to wander in the South Pacific in the spirit. Sun Cheng directly flew over Peru and Bolivia and entered Brazil. Soon after entering the amanbai mountains, he realized that he had been swept by a group of electromagnetic waves.


    When he was surprised, the forerunner soon appeared in his vision.


    "Master, welcome back..."


    Seeing that the visitor was the forerunner, sun Cheng''s nerves tightened for half a month.


    He nodded to the forerunner with some satisfaction, "it seems that you haven''t been idle during the time I left. You''ve done a good job. Has the reconnaissance system been installed around the base?"


    "Yes, master, I was inspired by the last time you told atlas to make several radiation balls. At first, Atlas wanted them to make several sets of radiation balls with wider scanning range and stronger functions, but atlas proposed a better solution. They transformed a set of antps-59 ground to air surveillance radar. It works well ……”


    Sun Cheng suddenly remembered that he had indeed purchased a batch of arms from the United States in the name of the Brazilian military trade company.


    At that time, in order not to arouse the suspicion of the other party, in addition to Hellfire missiles, he also purchased a lot of things, including a set of antps-59 vehicle mounted ground-to-air surveillance radar.


    Antps-59 vehicle mounted ground to air surveillance radar is a good thing. It is a military ground to air surveillance radar manufactured by Lockheed Martin for the U.S. Army. It uses active electronic scanning array (AESA) technology and works in L-band (1.215-1.400 GHz).


    The rotating scanning frequency of the radar is 6 to 2 times per minute, which can provide 360 degree azimuth coverage, with a detection range of 10 to 740km, a maximum detection altitude of 305 km and a maximum detection elevation of 60 degrees.


    In order to prevent electronic and kinetic energy attacks, the radar also adopts frequency agility Technology (i.e. the technology of rapidly changing wireless frequency), which can be said to be an excellent vehicle mounted ground-to-air surveillance radar.


    However, made in the United States has always been very expensive. There are many cheaper European products and made in Russia and China. Therefore, in addition to the U.S. Army, only Egypt, Bahrain and China''s Treasure Island region have a small number of purchases.


    Needless to say, after the transformation of engineers, the antps-59 ground to air surveillance radar arranged by the forerunner around base 2 must be better.


    Otherwise, it is impossible to find sun Cheng without opening the core function at once.


    For atlas, they didn''t design and manufacture by themselves, but only modified the existing radar system. Sun Cheng was not dissatisfied.


    Cybertron''s technology is indeed more advanced than the earth, but engineers need not only materials but also valuable energy to rebuild a more advanced warning scanning system.


    In contrast, the transformation based on the existing equipment is a method very in line with sun Cheng''s current strength.


    Since he met the pioneer, sun Cheng stopped and didn''t choose to fly directly to the underground cave, but walked to the base with him along the mountain road.


    When passing a valley with excellent terrain 20 kilometers away from the base, sun Cheng couldn''t help stopping. He stopped for a while on a small hydropower station there in the river below, and then walked forward.


    The completed small hydropower station is now the main energy source of base 2.


    Engineers convert the electric energy collected here into standard high-purity energy liquid or energy block on Cybertron through the "energy extraction and conversion device".


    In contrast, the current function of several groups of diesel generator sets in the base is to supply energy for many equipment in the base.


    With more and more equipment being placed in base 2, the daily power consumption has become larger and larger.


    "Master... We have also selected a suitable site for the second group of small hydropower stations and have started construction, but there is no power generation equipment for the time being..."


    "I see. I''ll send it later..."


    In the amanbai mountains, there are few places suitable for the construction of hydropower stations, and there are great restrictions. At most, only some small hydropower stations can be built.


    Sun Cheng also knows this, so in order to develop faster, the contact between China and Russia he said before needs to be seriously promoted.


    Having thought of this, he was just about to ask the forerunner about the manufacturing of industrial robots in the base.


    Unexpectedly, before he spoke, the forerunner suddenly thought of something and said again: "By the way, master, seven days ago, a team of humans tried to enter the depths of the amanbai mountains. After I personally approached and investigated, I determined that they should be just a human geological expedition. In order not to attract attention, I only got a spearhead viper, put it into a tent and bit a person, so they had to evacuate!"


    "Geological expedition?"


    Sun Cheng frowned slightly. If it were them, they might be interested in the depths of the amanbai mountains.


    However, the forerunner''s strategy surprised him a little. After thinking about it, he gently nodded and praised: "yes, we will deal with them in the future. I''ll give you the security of the base. At least we can''t let humans close to the base within 100 kilometers in the next few years!"


    "Yes, master!"


    During the conversation, the mountain road of more than ten kilometers was soon completed.


    The forerunner obviously informed the base before. When sun Cheng and his two arrived outside the underground cave, artera and frenzy were already there.


    "Master, welcome back..."


    "I''m back!"


    Nodding slightly, sun Cheng took the lead and walked into the underground cave.


    It hasn''t been seen for half a month. It can be seen that there are some changes in base 2 than before.


    Industrial robots can be seen everywhere in the base.


    Just on the way to the main hall, he saw at least six industrial robots laying power lines and monitoring equipment on the wall.


    "How many industrial robots have been manufactured during this period?"


    Sun Cheng asked atlas them curiously.


    "After the hydropower station was put into operation, energy began to accumulate. Recently, we have manufactured 17 industrial robots. The reason why the efficiency will be improved so much is that we have completed an automatic production line of parts and components of industrial robots according to your requirements. With sufficient materials and energy, we can produce at least seven industrial robots every day!"


    This is already very efficient. After all, the parts of industrial robots are not shoddy. In order to make them move quickly, engineers designed them completely according to human mechanics, from legs to arms to most parts of the body, Even the parts production line made by Atlas is difficult to raise the efficiency.
