In 2024, Lin Xiaoman made a living selling vintage trinkets at a street stall. After an earthquake, he transmigrates to 2124, the "Nirvana Era." By then, Earth has endured the "Great Subsidence," with sea levels falling and tectonic plates reshaped. The ecosystem has been transformed by genetically engineered plants, creating glowing forests and rivers of liquid metal. Posthuman society has split into Cloud Dwellers, who upload their consciousness; Shapers, who undergo biological nanotech modifications; and Baseline Humans, who refuse extensive alterations. The super AI "Creator" governs the world, while society struggles with the "tyranny of collective consciousness" and "identity alienation."
Lin Xiaoman awakens a golden finger called the "Book of Faith," an ancient book-scroll tattoo on his wrist that levels up as he collects "faith points." He starts by selling "traditional human memory chips" and gradually builds a following. Along the way, he meets extraordinary female leads: Su Zhaoning, a cool and aloof Cloud Dweller administrator who longs for what is real; Chu Xiyin, a rebellious Shaper artist who seeks individuality; and Shen Qingtang, a gentle Baseline Human doctor who remains devoted to tradition. Together, they face Zhou Mingyuan, a Baseline Human official who envies him; Ye Han, a Shaper friend who turns dark; and Qin Zhao, a strategically minded AI spokesperson.
Using faith to connect different factions, he tackles the suppression caused by "collective consciousness" and exposes the truth behind the AI's experiment to "optimize humans into data units." In the end, he reshapes the human spiritual world with the "Divine Kingdom of Faith," helping posthumans rediscover the essence of "love and memory" as he and the female leads set out together toward an interstellar future.
