Forty-year-old Chen Fan returns to the turn of the millennium. In his previous life, he was immature and squandered his family's savings, making his older sister suffer countless hardships. Reborn, he resolves to turn over a new leaf and shoulder the family's burdens. By chance, he activates the Tide Oracle System and follows its guidance to gather seafood along the coast, repeatedly harvesting rare marine treasures. Together with his friends, he earns an honest living to support the family. He helps his childhood friend Wang Pangzi become wealthy, establishes a cooperative, and takes on the unscrupulous fishmonger Hei Lian Kun. After draining a dangerous pool, he discovers millions' worth of magnificent lobsters and leads the entire village to prosperity. Just as a once-in-a-century red tide arrives, Chen Fan takes his modified fishing boat into the raging sea to seek Blood Dragon Saliva, a treasure said to prolong life, confronting one deadly danger after another.
