When Ling Ya, a little immortal nun from Huiling Mountain, was saving people during a flash flood, a lotus birthmark on her wrist was exposed. After learning of this, the Su family father went up the mountain to search for his biological daughter who had been lost for eighteen years. Upon returning to the wealthy family, facing the pampered fake daughter and indifferent brothers, she was unattached to glory and wealth. By day she kept a low profile at home, and by night she went out for part-time jobs, using her personal abilities to help people solve difficulties. The brothers felt guilty and wanted to make amends, but Ling Ya calmly refused charity. The mysterious young noble Bai Jing, knowing that she bore the heavenly lightning tribulation, silently accompanied and protected her. She did not contend for family affection or wealth, single-mindedly pursuing cultivation, saving the world and guarding her heart amidst the mortal dust.
