After his long-distance girlfriend cheated on him, he tried to take his own life, only to stumble into a cultivation world within his dreams. He roamed that realm for hundreds of years, then inexplicably returned to the modern world after entering a blood-red forbidden zone. As he traveled back and forth between dreams and reality, he gradually figured out how to enter and leave the dream cultivation world and uncovered its origins: after the cultivation civilization of the previous cosmic era fell, powerful cultivators sent the spark of its civilization into the dream dimension so it could endure. He had entered by accident. Once he understood the nature of the dream cultivation world, he steadily regained his cultivation and discovered that Earth had long been under extraterrestrial surveillance. He led humanity in resisting the aliens, eventually conquered the universe, and became an immortal amid the mortal world.
