One Piece: Master of Genes

Mio was walkimg along the road with his little sister, and in the next second, he crossed into the world of One Piece. With a system capable of extracting genes, enrolling genes, fusing genes, and cultivating organisms, he started a pleasant little life in the world of One Piece. When he's free, he grabs the heavenly tribute dedicated to Celestial Dragons, or catches a few kittens and bunnies to raise them. Feeling bored, he just walks and strolls around New World’s major powerhouses. Life is so beautiful, why bother~ Disclaimer: This is a translation and all the credit goes to the original authors of the story. Read upto 40 chapters ahead on Patreon patreon.com/alex_1000
