In the corner of a small fishing village on the Yin-Yang Continent, a few children gathered together. Among them, a young, small, and scrawny boy with brown hair suddenly climbed onto a roof, looked at the blue sea in the distance, and let out a vow, "I must become the Sailing King!"
After the human empire conquered the entire Yin-Yang Continent, the human population continuously increased and the amount of arable land kept decreasing.
There were already more and more sights directed toward the endless open seas.
Especially the lord of this territory, Grand Duke Wellington, who fundamentally enjoyed risks and adventures, was full of explorative spirit.
Under his encouragement, the entire territory's navigation techniques advanced endlessly, and they could already build a huge ship that could sail the high seas and bring about rich fish harvests.
