Xu Qian traveled to a world where he could contract spirit beasts, and obtained the status of a "corrector" during the journey. He awakened the system and contracted the first spirit beast, a space-time beast. After learning the meaning of the "corrector" identity, in order to prevent the invasion of other worlds, Xu Qian began to use the system to solve the alien world, in order to strengthen the system and his own spirit beasts.
