The world is trapped in a deadly game initiated by the mysterious organization "Ark". "Emotions" become the currency in circulation, and the gears of destiny begin to turn.
Wang Hanyu was originally a student at the Academy of Fine Arts, but due to the mysterious disappearance of his sister, he unexpectedly started to advance in his abilities. He was forced to become an "emotional auctioneer", relying on his special ability to sense residual emotions at crime scenes to survive in one case after another. Every time he perceives the criminal's emotions, it's like being in an endless purgatory, excruciating pain, but it also brings him one step closer to the truth.
Xu Ying, a calm and wise former detective, was dismissed for investigating "Ark". She joins hands with Wang Hanyu and uses her "logical brain" and technical support to become the anchor connecting Wang Hanyu to the normal world.
The "Ark", which controls everything in the dark, adheres to the absurd concept that human emotions are the source of all evil, and attempts to collect pure emotional samples to create a new world of "absolutely rational peace." Wang Hanyu's sister unfortunately became a victim of their plan.
In the process of pursuing the truth, Wang Hanyu's abilities gradually became stronger, but he also fell deeper and deeper into the whirlpool of emotions, facing the crisis of addiction and depersonalization. From using abilities to survive, to fearing abilities and wanting to get rid of them, to finally understanding and controlling abilities, he continues to grow on this thorny road.
As the "Twilight of the Gods" auction approaches, all forces gather together. In this huge VR emotional space, Wang Hanyu went through layers of rules and strange games to fight the strongest enemy. When he finally found his sister, he found that she had become the cold "God's Key".
In this battle that concerns all mankind
