Hải Vương Ký is a strategy game for mobile devices that allows you to collect and train powerful warriors to fight for you in idle moments, as well as reap the rewards when you’re not idle at all.

The game is based on the original manga series by Oda, where players are able to explore the vast oceans of the planet and conquer the treasures of the world.

Players can choose to play in either solo or multiplayer mode. In solo mode, players will have to build their own army and fight against other players in real-time combat (RTC) battles. In multiplayer mode, players will be able to fight with other players in an RTC battle, or they can fight with the computer.

If you are looking for an idle game that is easy to play, has exciting gameplay, and will provide you with a rich gaming experience, then Hải Vương Ký is the perfect game for you.
