Review Detail of Khagan in Super Godly Machine Army

If you want to pass time, you can read this novel. The translation quality is good so it feels smooth to read. However, don't expect any sort of intelligence from anyone in the story. They're all brain-dead. They all feel like machines programmed to do certain actions, and I'm not talking about the mechas. Especially the MC. With the cheat system he has, he could plan a bit better and without any risk to himself, become a top level force in the world. At the start of the novel, MC should have shown the strength of his mecha (level 1 of the internal force?) to the original elders of the Sirius Gang, instead of showing weakness, letting them openly rebel and then killing 'em off. Then, he would act like a normal gang leader, while his mecha could form a secret force who went around killing monsters and barbarians, buying low level herbs from all around the world, without ever showing himself to the world once. His cheat system gives him that option, so why not use it?
