I Became a Second-Hand System

Hello everyone, propriety is me, I am Su Xiaokong. Please allow me to tell you my experience in a few words... (Omitting a billion words). Introduction: The thing is like this, my soul was arranged by the system under an ancient routine that shocked the world, but... Just when I grinned before I could laugh out loud, the system suddenly failed, and then I became a scapegoat and a second-hand... Phew, I have become the next system, cultivating immortals, traveling through time, zombies, exploring, war, etc... As a system, I travel across thousands of worlds, looking for thousands of hosts. Let's see how I lead the major hosts to fight for dominance in one world, and see how I finally assemble all the protagonists to fight in the final battle!
