"I am the poison pretending to be the cure."
On Earth, he was a brilliant, cold, and rational surgeon who viewed human biology as a machine waiting to be perfected. Now, he has been reborn in the brutal, freezing Northern Plains of the Gu World. He is Ju Yang—the man fated by history to become the legendary Rank 9 Giant Sun Immortal Venerable.
But there is a fatal catch: he is an Otherworldly Demon. To Heaven’s Will and the all-encompassing Fate Gu, he is a virus that must be eradicated the moment it's found.
Surrounded by tribal meat-grinders and the watchful eyes of hidden entities, Ju Yang realizes that brute strength is a fool's gamble. To survive, he must play the ultimate game of deception. He dons the flawless mask of an arrogant, hedonistic young master who relies purely on brawn and beast enslavement.
But in the shadows, he wields his surgical intellect to dissect the laws of this world. To Ju Yang, allies are pawns, enemies are resources, and peerless beauties are not just trophies—they are the ultimate cultivation fuel for the goal of Eternal life . Uncovering deeply hidden, unorthodox methods, he transforms his darkest desires and most intimate conquests into a terrifying engine for rapid cultivation and high-speed scheming.
The Northern Plains is a brutal chessboard, and the current players think they are kings. But they are about to meet a sociopathic surgeon wielding the scalpel of fate.
Watch as Ju Yang dissects the Gu World, steals the heavens' luck, and forges a terrifying new glory.
