Lin Yu transmigrates.
He arrives in 1985, becoming a poor fisherman with no parents and a debt of three hundred yuan.
A broken boat, a torn net, a dilapidated house. The villagers are waiting to see him make a fool of himself.
Luckily, he binds to an Ocean System:
It can locate schools of fish, upgrade fishing gear, and predict the weather.
His first net haul brings in three hundred jin of fish, worth three hundred yuan.
He thinks this is the start of his fortune.
That is, until he risks entering the reef-strewn waters and finds a wooden box on the seabed.
Three characters are carved on the box: Lin Yongshun.
That is his grandfather's name.
Thirty years ago, his grandfather also went into these waters and never came back.
What is inside the box?
What was his grandfather searching for?
What secrets are hidden beneath the sea?
