After being introduced by Auntie Liu, Jiang Chaosheng marries Shen Qinglian and takes on the Shen family's debt of 30,000 yuan. He repairs their old boat and sets sail with his spirit bird, Shuangling. Using his extraordinary abilities and courage, he catches fish, turns his fortunes around, repays the debt, and obtains a Water-Repelling Pearl. From then on, he dives for abalones, rescues his father-in-law Shen Shoucheng, and brings Haifeng Trading House under his control, establishing the rule of 'taking the big and leaving the small.' From a family burdened with debt, they become a family that turns the vast sea into a dependable yearly granary, enjoying increasingly prosperous days.
