Player Xu Mo entered "Old Days Recovery", and his physical body dissipated, residing inside the orphan Bai Feifei. Xu Mo is familiar with the plot, and can control her combat to reload; Bai Feifei is determined to be a scavenger to protect the weak, and the two share a dual-soul symbiosis. They rushed to the Black Smoke Coal Mine, uncovering the secret of Dawn City elites using living people to create mutations and sealing the evil god's "Real World". Bai Feifei relied on her talent to withstand the erosion, winning the Heart of the World; the Masked Divine Concealment Society fabricated by Xu Mo was regarded as an ancient organization sheltering evil gods. After entering the inner city, the two investigated strengthening potions, exposed hidden dangers through a campus storm, and were ambushed by United Pharmaceuticals and the Huang and Li families on their way to the potion voting assembly.
