I, the Sea Slave, Start the Game, and the Contract Goddess Builds an Aircraft Carrier!

This is a fantasy ocean world called "Blue World". The ancient continent sank, and civilization continued in the form of navigation among countless islands. This is a cruel age of navigation where "the strong is king and gunboats are the truth". Wealth, power, slaves, sea beasts, ancient ruins and strange natural disasters together constitute the main theme of the world. The soul of a modern top ship engineer traveled to another world and became the lowest sea slave. In the desperate situation at the beginning, he contracted with the imprisoned goddess, activated the "Symbiosis Ark System", used modern technology to crush the fantasy age of navigation, built an invincible fleet, and became the king of the four seas!
