On the third anniversary of Lin Chen and his girlfriend Su Qing, he was betrayed by Su Qing and the rich second generation Wang Hao, and was thrown into a desperate situation as bait in the "Game of the Gods". When he was about to die, he activated the "causal deduction system" to predict the results of different choices.
In the first level "Doomsday Cinema", Lin Chen relied on the system to break through multiple fatal traps, and used Wang Hao's greed and Su Qing's selfishness to set up a trap, causing the two to suffer the consequences. During this period, he formed an alliance with the mysterious female player Ye Xue, and worked together to defeat the violent Wang Hao. He successfully survived and received huge rewards and the right to purchase contraband.
Entering the second level "City of Eternal Night", facing the suppression of the blood moon and the rule of "The Night King is Immortal", Lin Chen saw through the core loophole - the Night King is actually an aboriginal NPC disguised as a player. He cleverly used the "Shackles of Cause and Effect" prop to backfire the rules of "Blood of the Betrayer" to the game manager "The Watcher". While destroying the Night King, he triggered the "God Killer" achievement and gained the authority to change the rules of the game. In the end, Lin Chen changed the rules and forced the "spectators" to become defeatable chess pieces. Together with Ye Xue, who had escaped the curse, he transformed from a passive chess piece to a chess player who dominated the chess game.
