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

- Description from novelupdates

I transmigrated to the Great Qin empire to find myself a famous good-for-nothing in Ye Manor and the subject of ridicule of everyone. But thankfully, my dantian is the planet Earth.

When the Earthlings cultivate and comprehend anything, it will also turn into my own cultivation and comprehension. Each time one more Earthling reaches First Honor Inborn Level, I’d be able to add on the strength of an First Honor Inborn Level to my own strength.

There are 1.4 billion people on this Earth. I’ve hit jackpot.
