Villain? Nah. I'm just here for the harem. - Chapter 20: The Shadow Beckons

Chu Yunsheng’s head hurts every time he wakes up. Because he is usually either lying in the villain’s bed, or had just gotten up from the villain’s bed.

The reason why villains are called villains is because they are extremely lethal and vengeful… and they love to blacken…

Villain: Bastard, I will castrate you!

Chu Yunsheng: …Oh.

- Description from Novelupdates

Is Magic really just a wish machine? No! In a universe where Magic truly exists, the ultimate nature of Magic must be as simple and aesthetically pleasing as the laws of physics. This is the story of a mass-produced magical war tool who learned the ultimate nature of Magic. But what of it? Just as birds can fly without understanding aerodynamics, magicians can use Magic without grasping its ultimate nature. Learning the ultimate nature of Magic doesn’t mean the tool can instantly transform into a great magician. But yearning for knowledge is a human instinct, and curiosity is the primary driving force of human civilization. Even for Magic, which should seemingly defy explanation, humans hope to understand its inherent operational laws. The pursuit of Magic’s ultimate nature requires no reason! The story in this book takes place in an era where steel and gunpowder dance together. Here, firearms are on the rise; armor remains the main character; military theory is changing rapidly, with endless innovations in systems and techniques. And this world has something more than ours: Magic. The world is undergoing a profound transformation, and no one can remain detached from it...

Following a brutal and tortured death, a former assassin, known only by his codename Kuro, is given the opportunity to reincarnate in another world, a world with magic and monsters. Armed with an unrivaled healing factor and an inhumane pain threshold, Kuro opts to go for a reckless direct approach in this world instead of a stealthy and cautious one, and as a result, slowly gains attention bit by bit.

Having previously been a loner in his old life, he interacts and befriends people for the first time in his existence, however, his blunt nature also sees him making just as many enemies, both big and small. By combining his old assassin skills with the magic powers of this world, along with his high resistance to pain and rapid regeneration, he doesn't take long to establish himself as a formidable force in this world.

Initially, Kuro only faces minor threats, like weaker monsters and bandits. But before too long, the threats slowly but surely become more and more severe…from Zombies to a bloodthirsty empire to Vampires and Demons, and even divine beings…however, as the enemies he faces grow stronger, so does Kuro, gaining rare powers that have never or rarely ever been seen in this world…

Xie Tao had always believed in science until one day, a meteorite smashed into his yard, forcing him to bind to a heroic world saving script. The worst thing was that the script didn’t even follow common sense.
