Two powerful world masters from another world died together. A powerful artifact was scattered in modern times due to the aftermath of the battle. The protagonist picked it up by chance and became the only immortal cultivator in the world. Being an immortal cultivator provided the protagonist with many conveniences, and he became prosperous. An accident allows the protagonist to enter the special space of the artifact and awakens the soul of the sleeping realm master. The soul escapes and lurks in this world. After a period of time, the realm master succeeds in seizing the body and becomes the final boss trying to take back the artifact. The protagonist grows up and fights wits and courage with the realm master. Because the world lord is not adapted to this world, the protagonist can still deal with it in the early stage. As the world lord slowly adapts to this world, where should the protagonist go? What choice should be made in the end? This novel and its characters are purely fictitious.
