In a coastal fishing village in the 1980s, the male protagonist Wang Hu was a reckless gambler in his past life, gambling away all his family property, constantly beating his wife Cuilan, forcing his wife and daughter to leave, angering his elderly father to a fatal stroke, and accumulating massive gambling debts. He was chased by the local ruffian Sang, fell into the sea, and died. At his dying moment, looking at his broken family full of remorse, he accidentally reborn back to the moment he was chased and fell into the sea. When falling into the water, he saved a century-old sea turtle entangled in a fishing net. To repay the kindness, the turtle spat out a spirit bead. After swallowing it, Wang Hu gained heaven-defying abilities: X-ray vision of fish and shellfish on the seabed, infinite underwater breathing, instantaneous healing of trauma, and evildoers maliciously targeting him automatically suffering bad luck.
