My parents left behind millions in debt from a shipwreck, and Yu Xuan is cornered by creditors demanding repayment, accidentally binding a dragon ball within his body. From then on, the ocean holds no secrets in his eyes: magnificent lobsters, wild large yellow croakers, sunken ship treasures, and deep-sea king crabs make him rich and slap faces net after net. But the stronger the dragon ball gets, the more he discovers—his parents' shipwreck back then was no accident, and beneath the deep sea, another dragon ball seems to be calling out to him.
