When his consciousness awakened in the deserted square, Lin Chen found that he and dozens of strangers were thrown into a strange dimension called "The Realm of Illusion". Everything here is reset every twenty days, and behind the cyclical survival game lies the unconscious control of the ancient god "Heart-Eating Webweaver" who feeds on emotions. The roots of the ancient gods spread underground, whispers are hidden in the mist, and extreme emotions will be infinitely amplified, becoming nourishment for harvesting souls.
The "Twelve Divisions of Illusion" are like prisoner managers, controlling strange rules such as light, shadow, sound, time and space. They are not only servants of the ancient gods, but also have hidden ambitions to break free. Former special soldier Chen Feng's fist can break rocks, but cannot stop the accountability of his comrades in the illusion; physicist Professor Li uses formulas to deconstruct the supernatural, but glimpses the secret of the birth of ancient gods in the murals of prehistoric ruins; mysterious ancient book restorer Zhao Ying can read the ancient gods' texts, but struggles between redemption and betrayal due to a family curse.
Lin Chen's awakened "data analysis psychic power" opened loopholes in the rules, and his girlfriend Su Qing's "spiritual empathy" comforted people, but also made the two of them the most tempting sacrifices in the eyes of the ancient gods. When the crimson mist swallows the illusion, when the twelve divisions' conspiracies intertwine into a web, and when the truth of the cycle reset points to the energy harvest of the ancient gods - they must collect twelve origin tokens within twenty days and activate the soul-suppressing array at the moonlight moment. Will he become an emotional sacrifice to the ancient gods, or will he use reason and goodwill to break the shackles of the cycle? In this desperate game that straddles reality and the void, every step is questioning the bottom line of human nature, and every decision determines whether we can see the dawn twenty days later.
