One Piece Emperor Wuten

Luffy became the Pirate King, obtained the treasure of the Grand Line, and finally overthrew the rule of the Celestial Dragons with his friends. Thousands of years later, a huge force of five pirate kings appeared in the new world. The government also has five huge countries and dozens of small countries, forming the Heavenly Kingdom Alliance, with nine elders and a mysterious king. The strength of each elder is no less than that of the Pirate King. The mysterious king is even more powerful and the strongest man in the new world. Wutian is one of the five pirate kings, called Tianwu King, and is the youngest of the five pirate kings. Wu Tian did not swallow the devil fruit, just because he has a time-travel system that can travel through the past. This is his time-travel benefit, because he time-traveled from a planet called Blue Star. This novel and its characters are purely fictitious.
