Su Mu was the most inconspicuous handyman in Xuantian Holy Land, with zero talent. His only comfort was to silently guard Lin Qingxue, a talented junior sister who was as dazzling as the sun, moon and stars. When he learned that his junior sister was destined to die and would perish on the eve of becoming emperor, he made a crazy decision. He found the legendary forbidden technique, and at the cost of his one hundred years of life and his entire soul, he summoned the "Guardian" from the future. He thought he would summon a cold and ruthless strong man, but he did not expect that the person who walked out of the rift in time and space was actually Lin Qingxue himself, who would become the emperor in the future! And this empress, who was extremely majestic and capable of killing at will, burst into tears when she saw Su Mu and knelt down on her knees: "Husband, I have been looking for you for a hundred thousand years!" Su Mu was confused. He just wanted to save his junior sister. How come the future junior sister became his wife and seemed to... Owe him a lot?
