This set only belongs to his tactics and combat methods. Sun Cheng gave it a very vulgar name - Private Legion.


    The so-called private Legion is also very simple to explain.


    Sun Cheng makes good use of the spherical space and the space bridge technology he will master in the future. He carries a private legion with him.


    When fighting with the enemy, he called a large number of troops unexpectedly to realize the rapid rolling of the same level.


    Even pull stronger opponents into the war of attrition, and finally use their own strength to forcibly defeat them.


    Almost a month ago, in the battle with the fallen in Cairo, sun Cheng tried to invest hundreds of robots, and even deployed dozens of improved heavy artillery locally.


    The result of that battle was not very good, even very bad.


    Sun Cheng has invested a large number of robots in the battlefield. The manufacturing cost alone has exceeded US $1 billion.


    Unfortunately, he is facing the existence of an ancestor of Cybertron civilization, and the strength of the fallen is still above the leader.


    In addition to verifying some of his tactics and assumptions in that war, sun Cheng probably realized a key, that is, he could not control hundreds of combat units at the same time with his own computing power.


    He needs to reduce these combat units to a certain number in order to ensure that he can control them with his own computing power at the same time without affecting his combat.


    After the end of the first world war with the fallen, sun Cheng has been constantly summarizing his gains and losses and improving his private Legion combat system.


    During this period of time, especially after reaching a joint sniping plan for sound waves with Starscream, all Decepticon engineers and engineers in the whole base 2 have temporarily put down their work and supplemented and enhanced his deficiencies and problems bit by bit.


    The weapons of the private Legion are not enough to threaten the Decepticons and Autobots above the leader level. This is a big problem,


    For example, controlling too many combat units at the same time requires a lot of computing power, which leads to sun Cheng''s need to concentrate on controlling these combat units, thus temporarily losing his action and combat ability.


    For another example, the performance of heavy melee robots is far lower than his previous assumption, and the number is enough.


    However, in terms of quality, dozens of heavy melee robots can entangle and destroy a Decepticon''s replica warrior, and have to pay a very high battle damage ratio. Its high cost shows the failure of this kind of combat robot.


    In view of these shortcomings, Decepticon engineers have enhanced and improved them in a valuable period of time before.


    Heavy artillery was temporarily excluded from his private Legion list by sun Cheng. They do have great lethality to Decepticons and Autobots.


    However, the artillery is too bulky and needs to be deployed in advance. After exceeding a certain distance, the computational power consumed by sun Cheng is even more terrible. Before replacing the new body, he will not consider re equipping the artillery for the time being.


    The heavy melee robot was also temporarily kicked out of his private Legion list by sun Cheng. In previous battles, the heavy melee robot needed to pay a lot of sacrifices to replace the replica soldiers cultivated in batches by Starscream.


    The production cost of this heavy melee robot is nearly one-third of that of a heavy self-propelled gun.


    This war damage ratio obviously can not satisfy sun Cheng. The new requirement he put forward to his Decepticons engineers is to improve and strengthen them more thoroughly, focusing on improving their survivability in the face of Decepticons.


    One day, it would be acceptable for him if his engineers could reduce the battle damage ratio of heavy melee robots and replica warriors of Starscream to less than 41.


    Of course, in the previous experiments, sun Cheng didn''t gain at all.


    The long-range sniper robot has performed surprisingly well in several battles. Although this robot is only equipped with a special anti equipment sniper gun, once it is approached by Decepticons, it doesn''t even have the ability to resist.


    However, relying on Sun Cheng''s computational power, they were deployed in the best shooting position three to four kilometers away in advance. Under his control, they even need only a few bullets to kill a Decepticon''s replica warrior.


    What satisfied him most was the low cost of the robot. With its expensive special anti equipment sniper gun and equally expensive bullets, the cost of a remote sniper robot was only more than 200000 US dollars.


    For its transformation, sun Cheng''s requirements are only to increase the maximum range of the weapon, improve the firing speed and accuracy, and incidentally develop more powerful sniper bullets.


    In contrast, another robot that performed well in previous battles and remained on his private Legion list is the air combat robot.


    This round air Fort provided sun Cheng with sufficient firepower in battle.


    The disadvantage of the first generation is that it is not powerful enough. It can only slightly hurt but can not hit the target hard.


    At the same time, its cost is also very expensive. The single cost of this large round ball with a diameter of about three meters is about US $8 million, which is nearly twice as expensive as a heavy self-propelled gun.


    Some time ago, sun Cheng''s Decepticon engineers urgently upgraded it.


    The firepower of the upgraded second-generation air combat robot is about 30% higher than that of the previous generation. The disadvantage is that the diameter is increased from three meters to four meters, the weight is increased by nearly one ton, and the endurance time is reduced by nearly 40% compared with that of the first generation.


    Overall, it is still not mature and perfect, and needs to be improved.


    Because no one knows when the sound wave will attack, base 2 has only reconfigured more than 30 long-range sniper robots for sun Cheng and 24 upgraded second-generation air combat robots.


    In the past few days, sun Cheng has been running in with them.


    He was satisfied with the overall performance. When he controlled no more than 50 robots, it would not affect his participation in the battle.


    However, once sun Cheng participates in the battle, the massive data feedback will still affect his ability to provide accurate shooting correction for remote sniper robots.


    Therefore, he wants to adapt to high-intensity combat and control a large number of robots for Legion combat at the same time, unless he upgrades his core again.


    Otherwise, sun Cheng can only wait until the new body is completed before he can be completely unaffected.


    He controlled dozens of robots to cooperate with himself. For a time, he fought back and forth with the big train. Even after the gradually recovered sound waves rejoined the battle, he just fell into the disadvantage.


    But with a sudden scream, sun Cheng showed a bright smile on his face.


    His reinforcements, the Autobots, are coming.
