I Will Be the Master at the End of the World

Su Ling traveled to four days before the end, after four days of countless loans and countless collection of supplies. The end is approaching, and Su Ling successfully becomes the zombie master: He thought he was a survivor, but he didn't expect that he would become the strongest master of zombies. With his own doomsday system, one day in the future, he would break the world's barriers and spread the zombie virus to the entire universe. He is both the kindest ruler of the universe and the most evil ruler of the universe.
