The Heavens Start from Zhetian's Sign-In

Lu Lu was working a boring job after graduating from college. A trip in search of excitement led him to inadvertently travel to Lu Lu, a useless heiress of the four major families of the Lu family in Heisha City, a small town on the edge of the floating world. He was accidentally bound to the sign-in system. He could activate the sign-in by gaining energy in a different world and obtain sign-in items. Since then, he has successively started his own road to domination and coolness.
