Steel, Guns, and the Industrial Party in Another World - Chapter 330:

DEATH COULDN’T KILL HIM—IT JUST GAVE HIM A NEW LIFE TO DESTROY.Reo Carter was a name that made even the hardest killers shudder. A perfect hitman—no hesitation, no mercy. Until his own crew turned on him, leaving him bleeding out in a pile of bodies that used to be his enemies.But fate wasn’t done with him.He wakes up in a world of nobility, magic, and honor duels—trapped in the body of Leonhardt Caulem, the weakest, most useless son of Duke Caulem. A spoiled brat with no skill, no spine, and a reputation so pathetic that even servants look down on him.They think he’s weak? They have no idea who they just brought back.- Swords and magic? He spent his last life dodging bullets—this is child’s play.- Dueling etiquette? A knife in the ribs is the only honor that matters.- A noble’s life of luxury? He’s had enough backstabbing for one lifetime, thanks.He was once a ghost in the underworld—a man who didn’t exist. Now, in a world where strength is everything, he’s about to remind them what true fear looks like.The hitman is back. And this time, he’s aiming for something more.#NobleByDayKillerByNature #TheyBroughtBackTheWrongMan #FromHitmanToDuke #SayYourLastWords
