Lu Chao, the poorest kid on Bailang Island, was forced back to the beach by his father's notice of critical illness. The operation fee of 30,000 yuan was like three mountains weighing on him. Just when he thought he was going to die in the tidal flats for the rest of his life, a blue light floated in the muddy water at low tide - the "Eye of the Tide" was successfully bound, and a high-value catch information was refreshed every day. The tide has gone out, and the land is full of opportunities: butter crabs, wild large yellow croakers, red grouper fish, and schools of fish all over the cabin. Each precise location has allowed him to go from being heavily in debt to contracting tidal flats, buying fishing boats, and venturing into the East China Sea. But the more money there is, the bigger the sea becomes, and the more jealous people there are. The uncles and nephews of the Lai family, the fishing tyrants at the wharf, and the capital with an eye on the fishing grounds all blocked the bow of the boat. The tide has faith, and people must have stability. This time, he not only wanted to earn back the money he owed, but also wanted to make Bailangyu's name resound further out to sea.
