Song Dong is reborn in 1999. To protect his younger sister from misfortune, he resolutely cuts ties with his patriarchal birth family, receiving only the old house and a dry well. Unexpectedly, he unlocks a spiritual spring dimension within the well. He uses the spring water to cure his mother's illness and joins his childhood sweetheart in fishing for rare seafood, steadily building his wealth. When his birth family repeatedly tries to extort and scheme against him, he responds calmly and holds firm to his principles. He purchases an ocean-going fishing vessel and leads his companions into the deep sea, protecting his family and making up for the regrets of his past life. Through his own hard work and determination, he grows into a king of deep-sea fishing and lives a life of his own making.
