Daughter has a high fever, wife is desperate, and the family is forcing a division of the household. Driven to a dead end, Lin Haichuan returns to the millennium, accidentally binding with the ocean treasure hunting system. From premium mud crabs in the mudflats to rare seafood in the deep sea, he relies on his own hands to earn his first life-saving money, and also takes back up his responsibility as a husband and father. This time, he not only wants to change the destiny of his family, but also lead the villagers to get rich by relying on the sea. The real treasure is never money, but responsibility, family affection, and the courage to start over.
