The supporting character's harem is very normal - Chapter 122 You are just my pawns.

The rivers and lakes carry wine with swords, the waist is slender and the palm is light.

The young man carried a long knife on his shoulder, and hung wine on his waist, striding forward, but the rivers and lakes in his heart were vaguely visible.

Turning a page in the book of troubled times, the rivers and lakes have been raining nightly for decades.

Looking back suddenly, the world has been shattered.

Betrayed. Ridiculed. Killed.That was my past life.I trusted the wrong people, and they buried me for it. But fate wasn’t done with me yet. When I opened my eyes again, it wasn’t in my old body—it was in a world overrun by the undead. And this time, I was one of them.A fucking zombie!But I’m not like the others. I think. I feel. I remember.What’s this voice in my head?[Welcome to the Silent Requiem System!]The system feeds me power, unlocking missions and skill buried within this body. I have one goal: rise in rank, take control, and make sure no one ever tramples me again.The humans I move with have no idea what I really am. To them, I’m just another survivor, clawing my way to the top. But in battle, I use my abilities in secret—manipulating the undead, eliminating threats, and turning every fight in my favor.But rumors are spreading. There’s talk of an undead hiding among them, unseen and unstoppable. If they find out the truth, they’ll hunt me down like a monster.And my past? It’s here too. The people who betrayed me in my last life are standing right beside me, unaware of who I am. But I remember them. They turned on me once—I won’t give them the chance to do it again.Then there’s him. The commander of the city, sharp-eyed and ruthless. He’s watching me too closely, asking too many questions. If he figures out the truth, I’ll have to make a choice: eliminate him, outplay him… or pull him into my trap before he can destroy me.Because in this world, power is the only thing that matters. And this time, I refuse to be at the bottom.***“How did you survive when everyone else died?”I guess death just didn’t want me.“Why do the zombies ignore you?”Maybe I just have a face they don’t like.“You were just a nobody yesterday—how are you suddenly so strong?”Hard work, luck… and a little bit of hex.“Why do I feel like I've seen you somewhere before?”Déjà vu’s a funny thing, isn’t it?“What are you?”Wouldn’t you like to know?

He died. Not by fate, not by accident, but as collateral in a hunt between beings beyond mortal comprehension.And yet… death was only the beginning.Chosen by a mysterious entity known only as Echo, a sarcastic soul from Earth is offered a chance at a second life. Gifted with ten draws from a divine treasury, he obtains powerful treasures, a rare bloodline, and a mysterious system known as the Limitless System.But what begins as a straightforward reincarnation takes a twisted turn when two dragon inheritances—Thunder and Fire—collide within him.Reborn not as a man, nor as a beast, but as an unknown species—a fusion of human and two True Dragon Inheritences—he awakens in a scorched battlefield beside a dragon egg, unaware that his birth was witnessed by fate itself.After surviving the near-fatal clash of legacies within him, he emerges anew… no longer Zaroth, but Primus Xal’Zaryon Drakonis, a name that shakes the very fabric of mana around him.With his soul, body, and bloodline perfectly harmonized between human and dragon, Primus sets out into an unfamiliar world ruled by ancient clans, dangerous beasts, and kingdoms teetering on the edge of Eternal War.But power always draws attention—and with the secrets of his origin, the Limitless System at his side, and a destiny marked by a Primordial-level Mark of Fate, enemies will rise from shadows unknown.
