Comprehensive Korean Manga: I, the Demon King of Swords, Do Whatever I Want

I am Kim Min-soo, the Sword Hero, but all that is surging in my chest at this moment is uncontrollable violence - why? Why can those bastards still wear such dazzling smiles when I am drowning in despair and almost out of breath? ! Oh, I almost forgot, I am not only the Sword Hero Kim Min-soo, but also the Demon King of Destruction Kim Min-soo. Since this world cannot tolerate my stability, then it is better to follow my wishes: my happiness is the only rule The world under my feet has long been a rotten seam monster - before the sword energy of the martial arts has dissipated, the magic of the professionals has hit me, the hunter's dungeon has appeared on the street corner, and even the pretentious plots in female comics have been mixed in. This broken world has long become a sieve full of holes, so why can't I have more fun? A princess who was neglected since childhood? Want to become the favor of the group by killing your father and brother? Okay, first kneel down and be my maid, A male protagonist who talks a lot about "redemption"? Okay, first watch me destroy your whole family and then talk about your bullshit redemption! A male protagonist who only knows how to fall in love but not eat? Wake up, this world has always been about the weak and the strong. You don't eat, I eat – after all, wasted "prey" has no right to live And those women who came from other worlds, just want to complete their mission and go home with a broken system? How naive. I'll crush that broken system on the spot and lock you to me Remember, I am Kim Min-soo, the brave swordsman, and the devil in charge of destruction. From today on, all the rules of this stitched world must revolve around my "happiness" - I will start doing whatever I want, and no one can stop me!
