The Apocalyptic Me has a full-featured system
When people work hard to gather resources one by one, he gets double the resources every time. When people hunt with knives and iron axes, he already has a sword qi farther than a bullet, and the knife slashes one prey at a time, without difficulty.
When someone has a military camp as a base, he has a base on the ground, underground, and even in the sky, and can strike at more than 30 military centers at the same time!
