An ordinary transmigrator: They do everything they can to cling to the System, relying on it and all kinds of rewards to crush the natives of different worlds with overwhelming advantages. Armed with the most powerful cheat, they climb to the pinnacle of life.
A high-spec transmigrator: What cheat? I’m the one who builds cheats by hand! What lessons learned? There’s no such thing as a useless ability. As long as your imagination is powerful enough, the whole world will dance to your tune. One man nearly unified the world with a three-second time stop, while another can stop time whenever he wants but only thinks about that one stupid thing!
[Elves at the center + world-hopping + an invincible protagonist!!!]
