Mosquito System: Blood Required
Ten years of being foolishly in love! That’s what it cost Zilu to realize the woman he loved was a predator—and he was just the prey.
Left heart broken and bleeding on a rooftop, Zilu watched his fiancée, Xena, laugh in the arms of his rival Arsh while they stripped him. He was supposed to die there, but the universe had a darker plan, and it came with a high-pitched buzz and a hunger that wouldn't quit.
[Welcome, Host. The Swarm awaits.]
Saved by a mysterious System, Zilu is given a second chance at life with a twisted catch.
To survive, he must become the King of the Aedes realm. He’s no longer a man; he’s a shadow, a silent fever, a tiny executioner capable of slipping through any crack and delivering a lethal, custom-strain of Dengue to those who ruined him.
But the System isn't just helping him settle a score.
It’s hungry. It demands a Blood Tax from every human he touches, and as Zilu harvests for the system, he begins to realize the terrifying truth. The mosquito form is just the beginning.
Every drop of blood he feeds the System is a key, slowly unlocking the gates to a long-forgotten Vampire Realm.
Zilu started this journey wanting revenge, but the deeper he sinks into the System’s hidden agenda, the more he realizes he isn't just hunting his ex-fiancée anymore...he’s becoming the progenitor of a nightmare that will swallow the world whole.

Chapter: Dawn BringerThe courtyard was packed.Thousands of people were standing out there. They were the survivors. The citizens of the Spire, the prisoners, the low-level guards who had broken free from the Chancellor's mind control. They were covered in dirt and blood. Many were heavily bandaged, leaning on each other for support.The moment I stepped out of the shadows and into the dawn light, the murmuring completely stopped.A heavy silence fell over the crowd. Thousands of eyes locked onto me. I shifted uncomfortably, suddenly very aware of how terrible I must look—barefoot, my shirt torn, covered in dried blood with a small black cat perched on my shoulder.Then a man in the front row dropped to his knees. He pressed his forehead to the ground.A second later, the woman next to him knelt. Then a group of armored fighters behind them. Like a massive wave rolling across an ocean, the entire crowd dropped to their knees in complete unison."Whoa," I took a step back. "Hey. Hey, stop. What are

Chapter: The First Dawn[Ding!][Congratulations, Host, for completing this side quest.]I stared at the floating text. The rain was washing the blood off my face, but I still managed to give the screen the most bombastic exhausted side-eye I could muster."A side quest? It wasn't even a task to begin with. I just flew here randomly after leaving the Hersley Palace. I nearly died a few times. Zeez!"[In anything you participate, it becomes a side quest Host.]"Don't talk," I groaned, letting my head fall back. "I am still incredibly angry at you. I’ve read web novels before, you know. Before all this... bug nonsense. All their protagonist systems help them grow strong. They give them god-tier weapons and cheat codes. And you? I can't even find you when I'm in critical condition, getting my skull bashed in by a thousand-year-old tyrant."[Sorry, Host. I am still trapped. Until I regain my full power, I cannot assist you properly.]I wiped a streak of dirty rainwater from my eye wincing as my fractured

Chapter: Finally Resting in PeaceThe air in the room suddenly shifted. It was replaced by the scent of morning dew. The smell of fresh rain on dry earth.A golden light pierced straight through the oppressive black clouds of the Chancellor's dark magic.Right in front of the kneeling souls, the air shimmered and split open.I held my breath.A woman stepped out of the golden light.She wore a simple faded dress. Her feet were bare stepping lightly. Beside her, holding her hand tightly was a little girl. "Mom?"The Chancellor’s voice broke completely. It didn't sound demonic anymore. It didn't sound like a thousand-year-old tyrant. It sounded exactly like the terrified little boy who had woken up in the middle of the night to the sound of an angry mob.He slowly lowered his hands from his ears. The darkness that had coated his skin for centuries began to flake away, revealing the trembling tear-streaked face of a broken man."Mom... is it really you?" he sobbed.Witch Shanan looked down at the tyrannica

Chapter: The Final Apology of Thousands SoulThe explosion was completely earsplitting.I hit the broken floor tumbling over the debris until my back slammed against a block of concrete.Through the chaotic dust, I saw a tiny shape fall to the ground."Midnight!"My panicked voice tore out of my throat. I scrambled forward on my hands and knees, dragging my bleeding legs across the sharp rubble. "Midnight, hey. Hey, wake up," my shaking hands hovered over his tiny body. I was terrified to touch him, terrified that my clumsy mortal fingers would somehow make it worse.A cough wracked his chest. A single drop of blood spilled from his small mouth. His green eyes half-open and glazed with pain."Meow-ouch," he wheezed, his voice so incredibly faint I had to lean in to hear it. "You owe me... unlimited premium tuna for this..."His eyes rolled back and his head slumped against the stone. He was breathing but barely. I gently placed my hand on Midnight's head for a single second. Then, I stood up.The deep gash on my thig

Chapter: Boom!The pain was entirely new.When I was a mosquito, pain was just a blunt pressure against my hard shell. A warning sign. But this? This was completely different.The shadow spike had only clipped my shoulder but my new human flesh tore open like paper.Hot blood instantly soaked my shirt. The air hit the open wound, and it felt like someone was holding a lit match directly against my exposed nerves."Ahhhh!" I screamed grabbing my shoulder. My human vocal cords ripped the sound from my throat."Zilu!" Midnight yelled from the pile of rubble. "Get up! He is right behind you!"I tried to push myself up off the floor. My brain fired a desperate signal to my four middle legs to push my body weight backward.But I didn't have four middle legs anymore.My body simply jerked awkwardly. My two fleshy arms gave out under the strange new weight of my human torso, and I collapsed face-first into a puddle of my own blood."Get up!" Midnight shrieked."I'm trying!" I coughed spitting a mou

Chapter: Hybrid Form UnlockedThe stench of burning flesh still lingered in the back of my throat.I stumbled away from the Arch-Chancellor, my glowing insectoid body trembled as the horrific memory faded into the reality of the ruined control room. I looked down at the broken, bleeding man on the floor.My proboscis twitched in profound disgust but beneath the revulsion, a quiet sadness anchored itself in my chest.He was a victim of the exact same cruelty that had plagued this world for centuries. He and his mother had been betrayed by the very people they had bled to save. It was a vicious unforgiving cycle. But as I stared at the thousands of innocent souls I now carried within me—souls he had trapped and tortured—my empathy hit a hard impenetrable wall.Pain is a tragedy, but it does not give your sins a free pass. It does not justify burning the world just because the world burned you first."You want taste?" I muttered, glaring at the system screen hovering in the rain. "Fine."I didn't reach for his
