When retired special forces soldier Li Xunzhou was pulled into the "Deadly Game," he thought it was just a cruel test of survival. The rules are the only ironclad rules - don't answer any questions, don't hold unknown symbols... Every violation will cost you death.
Until he met Shen Du. The mysterious hacker who always wears a black hoodie never reveals his real name, but he can navigate the dungeon rules with ease. He smiled and said to Li Xunzhou: "You are smarter than I thought." But Li Xunzhou only labeled him in his heart: dangerous.
Two people who are also used to being alone are forced to test each other and rely on each other on the edge of life and death. When Li Xunzhou broke the rules for Shen Du for the first time, and when Shen Du used the [Eye of Data] to see the irreversible old injuries in Li Xunzhou's body, they realized that what was more deadly than the rules was the heartbeat.
However, outside the game, another story is falling apart silently. The gentle medical student Gu Yun hides all his love in every sentence "I'll remember it for you"; the paranoid girl Jiang Wan uses [mirror copy] to forget again and again, but desperately wants to remember his face. Until the bank of Wangchuan River, she sacrificed her soul to die in exchange for him living and forgetting.
This is a story about rules and exceptions, memory and forgetting. When the truth about the infinite world is gradually revealed, Li Xunzhou and Shen Du must make a choice - should they live by the rules, or should they break everything for each other?
Intention: In the cage of despair built by rules, trust is the sharpest weapon; in the raging torrent of forgetfulness, remembering a person is the most heroic resistance.
