One-Click Upgrade: Super Decomposition System - Chapter 375

Adrien’s tale is a thunderous symphony of vengeance, mystery, and ascension. Awakened with no memory but wielding a shadow-forged blade, he traverses a fractured world where gods rule through fear and silence. His forgotten blood burns with the legacy of the Godslayers—beings once feared even by the divine. As he hunts corrupted gods and unearths shards of unimaginable power, Adrien evolves from a wandering enigma to a force capable of defying fate itself. Twisting through betrayal, hidden empires, and awakening legends, his journey is not just one of survival, but of reclaiming divinity to break the sky itself.

The empire has turned into the land of the undead due to a spell gone wrong. God summoned heroes from countless worlds to purify the empire and plant new hope. Lee Shin Woo, an ordinary earthling, was also summoned. As an undead, that is.

Silas Blackwood wakes up with a machine in his chest – his missing mother's parting gift to help him survive the war with the Fae. This “system” grants him bizarre abilities: neuromancy (magic of the mind), biomancy (magic of the body), and essomancy (magic of souls and essences). Oh, and it fused a leviathan's mana core into his body. Because why not become part sea monster?At Arcanium University, a military boot camp churning out mage knights, Silas finds himself targeted by rich brats who think being born with a silver wand up their ass makes them special. When they leave him for dead, Silas decides it's time to show these spoiled kids what real power looks like.As Silas grows stronger, he discovers he can upgrade himself by absorbing essences from magical beasts and demons. Just when he thinks he's got a handle on things, Silas learns his mother's alive, and now he's got a new mission: a rescue that'll take him and his friends straight into the depths of Hell.

Chu Chen silently watched the group of system hosts who had been playing with the system he created to the point of collapse, and drank tea very calmly.

“You don’t really blame me for the rewards you get. I’m only responsible for the system delivery system. You blame me for being like this…”
