Modern fishing enthusiast Zhao Qin accidentally travels back to a coastal fishing village in 2005, becoming a universally despised "good-for-nothing", and binds with the beachcombing and foraging system. Relying on a sand shovel to dig for razor clams, peanut worms, sea cucumbers, abalones, and large yellow croakers, he grows continuously amidst family affection, romance, and competition—from paying off debts and supporting his family to buying boats, going out to sea, and building a team. Facing the suppression of his ex-girlfriend Yin Na, Zhang Chengji, and others, he counter-attacks time and again with wisdom and luck, ultimately transforming from a down-and-out youth into a fishing village entrepreneur, reaping a successful career, family recognition, and Chen Xue's love. Leading those around him to achieve common prosperity, he also truly completes a complete turnaround of his past life.
