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

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

It is Sun Cheng who makes good use of the spherical space, and carries a private army with him the space bridge technology that he will master in the future.

When fighting the enemy, he can quickly crush his peers by summoning a large number of troops by surprise.

He even draws opponents who are stronger than himself into a war of attrition, and finally uses his own strength advantage to forcibly defeat them.

Almost a month ago, in the battle with the Fallen King Kong in Cairo, Sun Cheng tried to invest in hundreds of various robots, and even deployed dozens of improved heavy artillery pieces in the area.

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

The number of robots that Sun Cheng has put into the battlefield is very large, and the manufacturing cost alone has exceeded one billion dollars.

It's a pity that he is facing the existence of a patriarch of the Cybertron civilization, and the power of the Fallen King Kong is still above the leader.

In addition to verifying some of his tactics and assumptions in that battle, Sun Cheng's only gain was probably to realize a key, that is, he could not control hundreds of combat units at the same time with his computing power.

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

After the end of the battle with the fallen King Kong, Sun Cheng has been constantly summarizing the gains and losses, and improving his private legion combat system little by little.

During this period of time, especially after reaching a joint sniping plan with Red Spider to target Sonic Waves, all the Decepticon engineers and sappers in the entire No. 2 base have temporarily put down their work, and have made up for and strengthened the various deficiencies and problems he raised.

The weapons of the private legion are not enough to pose a threat to the Decepticons and Autobots with the strength above the leadership level, which is a big problem.

For example, controlling too many combat units at the same time requires a lot of computing power, which causes Sun Cheng to be engrossed in controlling these combat units, thus temporarily losing his ability to move and fight.

For example, the performance of heavy melee robots is far lower than he previously thought, and the number is enough.

But qualitatively, it takes dozens of heavy melee robots to entangle and eliminate a Decepticon replica warrior, and it also has to pay an extremely high battle damage ratio, and its high cost shows the failure of this combat robot.

In response to these shortcomings, the Decepticon engineers have made various enhancements and improvements to it in the past precious time.

Heavy artillery was temporarily squeezed out of his personal legion list by Sun Cheng, and they did have great lethality against the Decepticons and Autobots.

However, the artillery is too cumbersome and needs to be deployed in advance, and after a certain distance, Sun Cheng's computing power consumed to control it is even more terrifying, and he will not consider re-equipping the artillery for the time being before replacing it with a new airframe.

Heavy melee robots were also temporarily kicked out of Sun Cheng's list of his private legions, and in the previous few battles, heavy melee robots had to pay a lot of sacrifices to replace them when facing the replica warriors cultivated by Red Spider in batches.

And the production cost of such a heavy melee robot is almost a third of that of a heavy self-propelled gun.

This kind of battle loss ratio obviously did not satisfy Sun Cheng, and the new requirement he put forward to his Decepticon engineers was to improve and strengthen it more thoroughly, focusing on improving its survivability in the face of the Decepticons.

One day, if his engineers can reduce the battle damage ratio of heavy melee robots and Red Spider replicas to less than 4/1, it will be acceptable to him.

Of course, in the previous experiments, Sun Cheng actually did not gain nothing.

The long-range sniper robot has performed surprisingly well in several battles, although this robot is only equipped with a special anti-materiel sniper rifle, and once it is close to the Decepticons, it does not even have the ability to resist at all.

But relying on Sun Cheng's computing power, they were deployed in advance in the best firing position three to four kilometers away, and under his control, they could kill even a Decepticon replica warrior with just a few bullets.

What satisfies him the most is the low cost of this robot, including its expensive special anti-materiel sniper rifle and equally expensive bullets, the cost of a long-range sniper robot is only more than 200,000 US dollars.

As for its transformation, Sun Cheng's requirements are only to increase the maximum range of the weapon, improve the accuracy of the rate of fire, and develop more powerful sniper bullets by the way.

In contrast, another robot that had performed well in previous battles and was still on his list of private legions was the Aerial Combat Robot.

This spherical aerial battery provided Sun Cheng with sufficient firepower in battle.

The disadvantage of the first generation is that it is not powerful enough, and it can only lightly damage but cannot seriously damage the target.

At the same time, it is also very expensive, this large round ball with a diameter of about three meters, the cost of a single body is about 8 million US dollars, nearly twice as expensive as a heavy self-propelled artillery.

Some time ago, the Decepticon engineers under Sun Cheng urgently carried out a series of upgrades to it.

After the upgrade, the second-generation air combat robot has increased its firepower by about 30% compared with the previous one, but the disadvantage is that the diameter has increased from the original three meters to four meters, the weight has increased by nearly one ton, and the endurance time has been reduced by nearly 40% compared with the first generation.

Overall, it's still immature, imperfect, and needs to be improved.

Because no one knew when the sound wave would attack, the No. 2 base hurriedly reconfigured only more than 30 long-range sniper robots for Sun Cheng, along with twenty-four upgraded second-generation air combat robots.

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

The overall performance made him quite satisfied, and when he controlled no more than fifty 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 him to provide accurate shooting correction for long-range sniper robots.

So he wants to adapt to high-intensity combat while controlling a large number of robots for clan combat, unless he re-upgrades his core.

Otherwise, Sun Cheng would have to wait until the new body was completed before he could be completely unaffected.

Controlling dozens of robots to cooperate with him, he had a lot of dealings with the big train for a while, and even the sound waves that gradually recovered, after rejoining the battle, he only fell into a slight disadvantage.

But with a sudden scream, Sun Cheng had a bright smile on his face.

His reinforcements, the Autobots, came.
