Yu Yang, a graduate student at Ocean University, fell into the sea on a typhoon night to save scientific research data, and woke up as the "son of the sea god" of the primitive tribe on Bibo Island. Faced with depleted catches, raging pirates and obstruction by priests, he determined to use modern marine technology to rewrite his destiny.
Improved fishing gear and doubled the catch; predicted tides and proved "miracles"; set traps wisely to defeat pirates; and even pioneered "farming the sea, animal husbandry and fishing", cultivating pearls and establishing currency. Yu Yang transformed from a stranger into a "sea governor", leading the islanders across the civilizational divide. However, the exploration of mysterious shipwrecks and underwater ruins revealed the cruel truth of the world-destroying flood - this world was actually a testing ground for advanced civilization!
