Zhao Xiaoxin, the sixth-generation tide-catcher of Qingluo Bay, with a pair of eyes that recognize tides and goods, helps his cousin turn the aquatic product shop into the first in the whole city. Earning five million a year, his dividend is only given as twenty thousand, and he is kicked out with one kick. He lifts up an old wooden scale to set up a stall, live stream, run a cooperative, fight fake goods, and protect the sunken ship at the bottom of the sea, ultimately leading all the villagers of Qingluo Bay to sell true seafood of Qingluo Bay nationwide.
