In 2450, the "God of Games" descended on the earth and dragged the world into a terrifying game where the fate of the country was the bet.
Country Z failed two copies in a row, and its citizens' tyranny level soared to the critical point.
The 23-year-old police academy elite Lu Zhaoye was ordered to form the Ark Team to delve into the eighteen most dangerous dungeons of the game.
Each dungeon is a testing ground for human nature. Family, friendship, betrayal and redemption are infinitely magnified in extreme environments.
When the truth behind the game gradually emerges, we not only have to fight against the replica monsters, but also face the most primitive fear of mankind - ourselves.
