Gu Changsheng transmigrates to the Primordial World, where Pangu tells him that a great calamity is coming. As the chosen savior, he can return to Earth and reunite with his younger sister only after completing his mission. He had planned to lie low until the calamity was over, but just after leaving the beginner's village, he meets a girl who looks exactly like his sister. Is it coincidence, or has someone arranged it?
“If you dare bring my little sister to this hellhole too, I'll destroy your Primordial World.” From then on, Gu Changsheng sets out to uncover the truth and, along the way, save the world.
