- Description from novelbuddy

Yi Tianyun woke up from a sleep, and found that he awakened this Upgrade System. Crippled meridians preventing you from cultivating? No problem! With the Crazy Upgrade System, do quests, kill monsters, devour others' Spiritual Power, or refine some Elixir Pills, inscribe great arrays, and you can gain experience!Experience Value is too low? Don't be afraid, I have Double Experience Cards, Tenfold Experience Cards! Experience Value will explode, explode, explode, and levels will rise, rise, rise!“Huh, I've leveled up again?”

I once believed life a simple equation: the wealthy thrive, the impoverished endure, the unburdened soar. Yet, even the freest of birds find their wings clipped by unseen cages. In this world, no station offers sanctuary; suffering, an inescapable shadow, finds all. And in its grim embrace, all paths converge upon death.This is not a chronicle of fleeting hope.This is not a legend whispered of redemption.This is the harrowing saga of a man twice shattered by the cruel hand of fate.... crushed, betrayed, mutilated. A soul condemned to an endless cycle of reincarnation, dragged back to a world that refuses to release its grip, only to fall, again and again. Each return a fresh descent into the abyss.But will he forever kneel, a puppet to his torment? Will he remain the naive fool who clung to the illusion of kindness? Or will the fractured remnants of his being coalesce into a force the world has never witnessed? A mastermind forged in the crucible of despair. A monster destined to unravel all, even himself.This is the tale of Veythor: the man who defied the quietude of death.And perhaps… the man who will shatter fate itself.

Jin, a guy with no direction in life, through an unfortunate event gets his hands on a Hitman System. What transpired then was a struggle to escape the eyes of the cops while trying to complete the system’s missions. However, through a series of coincidences, he soon finds out that his parents’ death was not an accident. Read how he uncovers the veil that has obscured the truth from his eyes since childhood and finds out the darkness that hides under this veil. ‍
