The End of the World with a Difference

The end is near. A small number of humans awaken as forerunners. Having the privilege to go first and go to different "versions" of the world. Their duty is to go to various versions of the world, obtain power, props, and information, and then return to the original world to prevent the end of the world. And Zhou Baiyu, the shameful stranger of the forerunner, has made great contributions to all mankind. With his unremitting efforts... The end did not come in the end. But at the same time, he also made great contributions to the monsters. With his unremitting efforts... With just a little difference, the end came. The story... Has to start with him transforming the succubus.
