Zhang Xiaojiu has died once before. In his original world, the demon realm overturned the human world, wiping out humanity across the globe. His soul, carrying regrets, traveled back in time and entered the body of a baby before the catastrophe occurred. This time, he originally planned to hide away and simply survive. However, fate led him onto a path of saving the world. A white-clad angel of mercy sheds tears for him, a fiery policewoman takes a blade for him, and a gentle spirit demon faces death calmly for his sake. Brothers fight together with burning passion, while the women who love him stand by his side through life and death. Rising from the mud, he takes one step at a time, transforming from someone everyone calls a good-for-nothing into a powerhouse standing at the pinnacle of strength, admired by thousands.
