There were two novels that mentioned " King of the World ", namely " The Legend of King of the World " and " The Power of Dragon Ball ". Among them," The Legend of the World King: The Unrivaled Hero " was a Xianxia-Cultivation Civilization novel. It told the story of Han Jin cultivating in another world, building a force, fighting with heroes from all walks of life, and finally becoming the World King. " The Power of Dragon Ball is Supreme " was a light novel, a derivative doujinshi novel. It told the story of a professional fighter who traveled through the universe and stirred up trouble. I hope you like my recommendation. Muah!
