DAI 3 OUJI WA SLOW LIFE O GOSHOMOU (MANGA)

In my first life, I ended my life as a company stockbreeder. Luckily, I was reborn in another world, but I inadvertently defeated the Demon King and died there as well, working too hard as a hero. Undaunted by this past, I was picked up by a kind goddess and finally reincarnated as the 3rd prince in this life. Having inherited the magic, skills, and knowledge from my previous life, I enjoy a carefree slow life in a frontier territory! Surrounded by kind people, I hope I can spend this life leisurely ( I'm not flagging, right? )
