Bai Xi, as the last Longhushan Celestial Master in modern times, was blessed with great fortune, but due to the scarcity of ghosts and gods in modern times, he died with regrets as he failed to achieve enlightenment and become a god. After her death, she traveled to a different world that seemed peaceful but was actually penetrated by the shadow of Cthulhu, awakening the system. In order to prevent the protagonist from sabotaging their plan to summon the Old Ones, the fanatics constantly hinder her investigation of strange events. Once the protagonist fails, his sanity will be eroded by the Old Ones and he will lose his life.
In this world full of unknown dangers, Bai Xi's instinctive fear of Cthulhu's power affects her actions when facing powerful monsters. At the same time, she faced a crisis of trust because she was misunderstood by local residents as the source of the disaster. But with her understanding of the Cthulhu Mythos and the help of the system, she was able to avert danger after crisis.
As the investigation deepens, the countdown to the arrival of the alien gods begins. Bai Xi must collect special items within a limited time to fight against the alien gods. In the end, she succeeded in preventing the alien gods from coming, but she was also mentally traumatized by excessive exposure to forbidden knowledge. But Bai Xi did not give up. With the support of her helpers, she gradually recovered, and finally became an immortal and protected this other world.
