The Retired Supporting Character Wants to Live Quietly - Chapter 150 - Head Theoretical Professor Kaiden (2)

They say Knowledge is power. This was the truest fact; something Adam built his empire around.

He wasn’t always this rich. He wasn’t always this powerful. There was a time he too struggled to earn enough for the treatment of his sick and dying mother.

Yes, he still remembered that day, that Halloween Night. The starry sky under where his life turned anew, changing for eternity.

Follow Adam’s Gospel; a young man juggling between different duties with only two goals.

Becoming rich, growing powerful.

Crossing to One Piece world, he became Roger’s younger brother.

Unexpectedly, Gol-D-Roger who was in his fifties had a teenage brother. But he was so weak.

Fortunately, at the age of sixteen, he actually found himself with a possession soul system.

He had attached to the master IP man, also to the White Phoenix and to Ge Nie with his strong ability of the Hundred Step Flying Sword.

If you think that he can only Purchase these? Then you’re wrong!

Pain, Itachi, Ichigo Kurosaki, as long as there is money, any soul can be Purchased.

He—an enigmatic and cold-blooded soldier with a mysterious background.
She—a ruthless and bloodthirsty spy.

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?
