In our village, there is an unwritten rule that when a son turns eighteen, the father must be thrown into the sea to feed the sea turtles.
According to legend, the Daiyu Island where our village is located is a rootless immortal island. There are three giant turtles under the island, one carrying the island while the other two wait below, exchanging roles every ten thousand years, taking turns to bear the burden.
In order to ensure that the giant turtles fulfill their duties, the village throws a person into the sea to feed the turtles every three months, and the person chosen to feed the turtles is selected from among the sons who turn eighteen.
