Beneath the city's glittering neon lies a hidden world where gambling arts, supernatural powers, and ancient martial arts intertwine. Ordinary people rely on luck to win or lose, but the true masters can control dice with their minds and alter their fortune by manipulating qi. Underground casinos are scattered throughout the city, where life-and-death wagers take place every night. Legend has it that anyone who wins across all nine provinces can enter the Heavenly Seat Rankings and gain the power to change fate. Money is only the most superficial stake here. What is truly traded is lifespan, fortune, and even souls. Some use ancestral bronze tokens to glimpse three seconds into the future; others awaken spirit-seeing eyes by swallowing strange objects. And hidden clans control the city's entire web of financial fortune. Rising from the bottom, the protagonist handles cards with his left hand as though caressing fate, while his right hand cheats with the certainty of Heaven's will. Step by step, he tears away the city's fantastical facade, turns his life around at the gambling table, and uncovers the ancient rules hidden in the cracks of reality. The world may look modern, but it is secretly ruled by countless mystical organizations. And the greatest casino has never been above ground: it lies deep within the human heart.
