Cheng Zi, a sunny and cheerful boy, was accidentally bound to the "Attribute Lottery System". Draw a lottery once a day to get random attribute points such as strength, speed, intelligence, etc. It seems like a simple ability improvement, but there are hidden loopholes in the rules - the lottery probability can be affected by logical deduction and psychological games.
Cheng Zi soon discovered that this system was not an isolated gift. There are people who also know the rules lurking in the city. Among them, the psychological twisters headed by Lin Mo see the lottery as a tool to play with others. They manipulate probabilities, set traps, and use their attribute advantages to crush ordinary people.
Cheng Zi must use his sharp mind under the sunny appearance to unravel the villain's conspiracy step by step. The lottery is no longer a game of luck, but a game of life and death. Every time an attribute point is added, it is a piece on the chessboard. When Lin Mo showed his true face, Cheng Zi understood: the real victory is not to draw the highest attribute, but to let the opponent never guess where your next move will be.
