Enlightenment in the Second Dimension

Different time and space, same world. Kill one person to level up, have double skills, and have similar super-series transformation skills. There is fighting and killing, and the more you fight, the stronger you become. One-on-one battles are required. Killing by leapfrogging is easy. Invincibility is only a matter of time.
