The last Vampire with the Hero summoner system: I get 5x their powers - Chapter 14: Letter

The end of the world comes suddenly, and when most people turn into zombies, order and morality collapses completely. Our Protagonist is determined to stay alive.But he isn’t completely alone. He has a special pet; a Thousand-Legged Blood Centipede, a powerful creature that gets stronger with every battle.As he fights through the chaos, the centipede transforms into a Six-Winged Blood Centipede, then into an Eight-Winged Golden Centipede, and finally into a Ten-Winged Divine Centipede. Together, they become a powerful team that can change the future, even in the darkest times.The protagonist isn’t a hero; He kills zombies and keeps some in captivity.He saves people, protects people, and draws human blood to feed zombies.As the remaining people fight over what little they have, the idea of right and wrong is forgotten. He walks a thin line between being a hero and a villain, doing whatever it takes to survive.

[You have successfully devoured your target.][Your strength has increased by 250.][Your speed has increased by 200.][Your defense has increased by 300.] [You have acquired the Golden Immortal Bloodline.][You have acquired the Chaos Beast Physique.][Your cultivation has increased.][You have accumulated Madness.]The Era of Chaos is upon the Cosmos once more leading to various kinds of Chaotic Rifts spawning randomly.Meanwhile, a 26-year-old actor on Earth, Pascal Margrave, transmigrates into the body of Caelum Goldheart.

Caelum quickly realizes that while he is the [Host] of the World Devouring System, he is not its true [Master]. Failing to complete the system's milestones within the designated time will lead to his soul being tortured in the Netherworld for all Eternity.Join Caelum on his journey as he attempts to take control of his own fate, uncovers the hidden plots around his transmigration and becomes the dominant power of the Cosmos.

When other people experience a body transformation, it is inevitably either male to female or female to male.

Me? I wake up to find myself transformed into two different bodies.

Both a male body and a female body, one conscience operating two bodies, all sorts of embarrassing moments.

Walking together normally makes other people think that I am sweethearts with my other-self, such sadness.

Also, the entire business of a hero rescuing the beautiful maiden, I call Bull.

I get slashed by a sword and my female body gets abducted, and he wants me to thank him?!?! Can it be less of a tragedy?

Welcome to NecroCorp – Where War is Always in Stock!“Now with 15% off main battle tanks, because peace is bad for business.”Hello, traveler!Looking for a bone-forged sword? A modular mana cannon? Perhaps... a discounted main battle tank for your next kingdom raid?Oh wait, you're not a customer, you're a reader.Right. This is probably where I give you my “tragic backstory.” Fine.I used to be human.Then I died.Now I'm a Lich with a factory in a dead dungeon, a skeleton workforce that doesn't need lunch breaks, salaries, and a magical system that rewards me for selling stuff. So, I did what any sane undead would do: I started an arms corporation.Now I sell weapons to orcs, goblins, elves, humans, anyone with a grudge and a pile of magic stones. Need siege engines? Got 'em. Crossbows that reload themselves? Yup. Flamethrower golems? In development.But here's the trick: you can’t sell weapons if there’s no war.So when the world started calming down... well, I may have encouraged a few border skirmishes. For marketing purposes. Nothing personal. War drives demand, after all.So, if you're here for drama, explosions, undead capitalism, and morally questionable business strategies wrapped in bone and steel, you’ve come to the right dungeon.Just don’t ask about the warranty.There isn’t one that lived to tell and ask about it.
