Orphan Bai Feifei heads to the God-Suppressing Ministry to take an assessment, and by a twist of fate forms a symbiotic bond with Xu Mo, who comes from another world. Xu Mo loses his physical form and can only inhabit Bai Feifei's body. The two agree to support each other and advance for mutual benefit. Relying on his unique life experience, Xu Mo uses Bai Feifei's body to break through his own limits, defeats unfair irregularities in the assessment, uncovers hidden hazards buried in the mining area for years, and unexpectedly subdues a rare high-tier spirit vault. One person and one spirit accompany each other, walking hand in hand through a treacherous and bizarre world, breaking through heavy difficulties all the way.
