I was just your average student—no special talents, no grand dreams, and most importantly… no girlfriend. My days were spent grinding through life, with my only true passion being games, mangas, and web novels.Every day, I’d see couples walking by, holding hands, whispering sweet nothings, and I’d think, Hell yeah! When's it my turn?! I mean, I deserve a cute girlfriend too, right? Someone to hold, someone to kiss—just once, please!But, of course, life had other plans.One second, I was daydreaming about romance. The next? BAM! Truck-kun hit me with the ultimate rejection letter—straight to another world. When I opened my eyes, I realized I had reincarnated... but not as the hero, not even as the sidekick. Nope. I got stuck as some low-level villain—a total extra—the kind that exists just to get one-shot by the protagonist in the early chapters.The good news? I know this game inside out.The bad news? The whole world is out to kill me.But if they think I'm going down that easily, they're in for a surprise. Using my game knowledge, I'll dodge every death flag, exploit every loophole, and rise to the top! And hey, if I end up with a harem of gorgeous girls along the way? Well… let’s call it a happy bonus!This is my story—where I rewrite my destiny, break the game, and maybe... just maybe... finally get that kiss!Support this Shameless Author with Power Stones Gifts and Golden Tickets

This is a world where humans, demons and mysterious beasts coexist. Humans cultivate mysterious qi. Demons cultivate corporeal bodies. Mysterious beasts cultivate soul perception.

Some demon kings are able to sense things thousands of miles away. These demon kings rarely appear in the human world. Even if they emerge in the human world, they would reincarnate in human form; assimilating with mankind while seeking to breakthrough realms…….
