Su Chen and 11 others were kidnapped by a mysterious force, involved in the deadly "Abyss Game", and trapped in a closed space full of traps and puzzles. In a desperate situation, he activated the "Information Insight" system and could see hidden hints that ordinary people could not detect. Faced with the doubts and misunderstandings of Wang Hao, a conceited and reckless second-generation rich man, Su Chen relied on information gaps to resolve crises many times, counterattack and slap him in the face, establishing his core position in the team. He led medical graduate Lin Qingxue and others to crack the code of the secret room and see through the traps of the library of lies, gradually revealing the shocking truth that the game is not just about survival, but about screening "observers", and more advanced assessments and deep conspiracies are waiting ahead.
