The First Book by Fat Cat Eating Cookies

Yan Yun and Mo Fan, two transmigrators from Earth, struggle to survive in the brutal world of Versatile Mage. Yan Yun narrowly survives the bloody disaster in Bo City and binds himself to the mysterious Myriad Phenomena Sign-in System. When the military abandons the rescue effort, he charges alone into the demon lair and saves Zhan Kong, earning the military's goodwill. With the System and an iron fist, he establishes the City of the Forgotten in the wilderness, a refuge for displaced people, and quietly builds up his power. Years later, the Dark King descends, and humanity's strongest fighters are defeated. As despair spreads, Yan Yun steps out of the ruins where he has been signing in, with the shadow of the Nine Nether Emperor towering behind him. His cold gaze sweeps over the world: “Sorry, but I’ve already claimed the right to rule this plane.” From a city on the brink of destruction to the Shadow Emperor, this is an utterly invincible path of ruthless combat and cunning empire-building.
