It tells the story of the time-traveler Mu Feng, who was originally a cultivation genius encountered once in a thousand years by Prince Mu. However, due to the vision of the immortal coffin three years ago, he lost his Dantian and became a useless person ridiculed by the world. He was framed by his younger brother, Mu Lan, and was on death row for the crime of patricide. When he was about to die, he merged with the Immortal Coffin of Chaos to regain his cultivation. With the inheritance of the Immortal Coffin, he counterattacked all the way, killed his enemies, washed away his grievances, protected his sister Mu Yao, explored his biological mother's life experience, fought against villains such as the Beidou Star Sect, and finally embarked on a journey to the fairy world.
