Zheng Ming, the True Lord of Purple Clouds from the cultivation world of Xuanzhou, was ambushed by a traitor while undergoing tribulation. His soul unexpectedly transmigrated into the body of a down-and-out young fisherman with the same name in a fishing village on the Bohai Bay in the modern world. The original owner had been tricked by a friend into owing a million in loan-shark debt. His father was seriously ill and bedridden, and his little sister needed tuition for college soon. Desperate, the original owner went out to sea, met with an accident, and lost his life, allowing Zheng Ming to take over his body.
Faced with a penniless household and a final ultimatum from the debt collectors, Zheng Ming used a cultivator's spiritual sense to see through the seawater and find wild large yellow croakers and top-grade sea cucumbers hidden in the deep sea. By selling premium seafood, he quickly earned his first fortune and paid off some of the debt. But the shallow waters he had leased were rich in resources, and they soon caught the eye of Zhou Hu, the boss of the local seafood monopoly. Zhou Hu teamed up with the village bully to keep causing trouble, either trying to seize the waters at a low price or sending people to steal the catch and destroy the nets. He even secretly bribed the original owner's childhood friend to spy on Zheng Ming and keep sabotaging him.
With the three-month deadline drawing closer, Zheng Ming had to contend with Zhou Hu's open and covert attacks while adapting to the rules of modern society. Using his spiritual sense to explore the sea and ancient methods to nurture its waters, he gradually went from gathering seafood along the shore to leasing and cultivating the sea, building a thriving business in premium seafood. The ways of a True Lord from the old world's mystical sects kept colliding with modern capitalist monopolies and the intricacies of village life. As Zheng Ming overcame one crisis after another, he not only made up for all the original owner's regrets, cured his father, and put his little sister through school, but also transformed the once-poor fishing village into a prosperous place known far and wide. With his skill at gathering and cultivating seafood, he forged a legendary life of freedom on the fringes of the modern city.
