Many people in the world pursue immortality, but how can they spend a long life if it is boring?????????????????? When Kaguya was sealed, two sons were born, one was Black Zetsu and the other was Haxin. Black Zetsu inherited Kaguya's memory and planned for thousands of years to rescue Kaguya. And Haxin is a lonely soul wandering in the universe, but he accidentally inherited Kaguya's talent and bloodline, and gained eternal life. Because he is not a product of the world, he is an alien species, sealed by the will of the world, and will wake up after a thousand years. The nine-tailed demon fox roared, and the story unfolded.
