Lin Jianjun, a gambling addict and heavy drinker, unexpectedly reincarnates while playing mahjong at a small grocery store. He remembers the tragedy of his previous life: because he was obsessed with gambling and broke his promise to pick up his daughter, Lin Yuanyuan, on her birthday, she died in a flash flood. Overwhelmed by grief, his wife, Su Lan, threw herself into a river, leaving the family destroyed. Reborn on the very day the tragedy occurred, Lin Jianjun finally comes to his senses. He overturns the mahjong table on the spot and rushes out without hesitation to save them. At the same time, he awakens a supernatural clairvoyant ability that allows him to see through water currents, rock formations, and physical weaknesses in people's bodies.
