The World's Greatest Post Rider

The ten strongest in the world, the ten strongest in the world! Among them is the Sword Master, Manu! Born a servant, Wanyu returned to Joseon as one of the ten greatest fighters in the Central Plains. When I returned to Joseon to reconnect with my family, I found their home in ruins, and no one could find them... Meanwhile, the King of Joseon ordered Manu to take Hamheung Dasa's place. But isn't that a slang term? Isn't it? "Why me?!" The world's best. Manu, who's currently reading in the middle of the story, begins his own journey in Joseon!
