In Zhuyai Town, Liu Haixiu, in order to gather repair money for her boat, risked her life at the Evil Ghost Reef to save a spirit-guarding giant clam, and received a bright pearl as repayment of gratitude. To protect her large mansion with an underground dragon vein, Haixiu signed a merchant house long-term contract, turning kindness into enmity by using coarse sand to torture the giant clam to force the production of bright pearls. However, things obtained by force turn to ash in the wind; not only did she lose all her family property, but she also took on a huge debt of five hundred taels. Facing the shopkeeper's coercion of smashing the clam to take out the core, Haixiu pulled back from the brink at the precipice, risking her life to release the clam back into the deep sea to seek redemption. Unexpectedly, the turned-to-ash bright pearl led to the secret map of the peerless treasure "Sea Eye", and a storm of capital encircling the small town suddenly descended.
