Lin Yi, who was once an e-sports genius but had his career ruined due to a mistake in the finals, was accidentally bound to a mysterious system called "Chess Soul" late at night at the lowest point in his life. He is no longer a player who can only control chess pieces on the screen, but a "host" who can embody heroes such as "Iron Armored Guards" and "Shadow Bow Assassin" in the game into the real world.
However, this power is not a gift, but the beginning of a huge conflict. The pursuit of the mysterious organization "Dark Chess Club", the ultimatum from the official organization "Tianyi Alliance", and the invitations from the ancient forces calling themselves "The Lost Chess Club" followed one after another. Lin Yi discovered that the game he lost and the awakening of the system were not accidental, but the first step of a carefully planned chess game.
He is no longer alone. Su Li, a hacker girl with superb skills, can analyze the data of all things and find system loopholes; Lei Meng, a retired soldier with unique skills, has become the most reliable shield with his flesh and blood; there is even the mysterious Bai Luo, and the AI-K7 who is both an enemy and a friend... They gathered for their own reasons to form a team that seemed incompatible, but became deeply bonded.
In this "Game of Thrones" with reality as the chessboard and fate as the bet, Lin Yi must learn to trust his companions, control his power, and grow from an arranged "chess piece" to a "chess player" in charge of the overall situation. When the final "Tianyi Summit" comes, he will face the source of all conspiracies, uncover the truth behind the system, and lay down his last piece for the fate of all "chess soul hosts".
When the rules of the game invade reality, do you become a pawn or a game-breaker?
