In 1982, fisherman Chen Yan comes to his senses when his wife and daughter are pushed to the brink of desperation. By chance, he awakens the Sea God's Decree and gains the extraordinary power to command marine creatures. He leaves his deeply troubled family behind and vows to protect his wife and daughter at all costs. Using his newfound abilities, he ventures into the deep sea and repeatedly discovers rare treasures. Starting with the purchase of a fishing boat, he outsmarts the village bully and fights against companies illegally dumping industrial waste. Not only does he transform the fate of his own family, but he also leads the entire village in building roads and a harbor and developing deep-sea aquaculture. He overcomes typhoon and red tide crises, transforming a once-impoverished fishing village into a premier seafood production hub and writing a legendary story of environmental protection and shared prosperity.
