In 1985, the destitute Li Chen is reborn from the future, stepping forward at the critical moment when his parents are about to be swindled into a fundraising trap, tearing up the contract and saving his family from disaster. To prove himself, he uses his memories of the past life to venture alone into the deserted "Ghost Beach" to forage, digging up unappreciated spoon worms and making his first pot of gold. Afterward, defying all opinions, he contracts the muddy tidal flats north of the village, introducing scientific aquaculture concepts from pond clearing and disinfection to mixed fish and shrimp farming, moving forward step by step. Facing the villagers' mockery and malicious sabotage from competitors, Li Chen defuses them one by one with strength and wisdom, ultimately turning the mud flats that no one looked favorably upon into a mountain of gold.
