In his previous life, Shi Nian was deprived of his powers by his step-sister Shi Ranran, betrayed by his relatives, and eventually died in a warehouse fire. Before she died, she realized that the person who really saved her, broke her legs for her and loved her deeply was He Changnian who she pushed away. After being reborn and returning to school, Shi Nian returned with supernatural powers and countless vests to save his grandfather, protect relatives and friends, uncover the conspiracy of the fake daughter and mother, and track down Wan Guolun's cruel human experiments. She and He Changnian fought side by side against powerful enemies, vampires, shikigami, and battles between gods, and finally took charge of the throne of light and fire, making up for the regrets of their previous lives and protecting each other and the world.
