Eight-year-old Lin Mo is brutally abducted by cultivators, all because he is a one-in-ten-thousand innate Origin Body. A cultivator's strength can surge simply by touching his skin, and the yang essence within him can help people break through cultivation bottlenecks. He is, in effect, a walking cultivation treasure.
Just as his life hangs in the balance and his yang essence is about to be stolen, the God Devouring System suddenly activates! He can create fake yang essence to fool his enemies, devour their cultivation, and freely turn his constitution's alluring effect on or off. To survive, Lin Mo plans every step carefully, hiding behind the frail appearance of a child and repeatedly setting traps with fake yang essence to bring down those who covet him.
From the desolate ancient forests and bloody battles in Blackstone Market, to taking refuge at White Deer Academy, breaking into the ancient Thousand Mechanisms ruins, and accidentally entering the Black Miasma Marsh, the boy flees and fights his way forward. He can not only devour his enemies' cultivation, but also discovers a method of tempering his body with yang essence, rapidly improving his physique and strength.
But the secret of his innate Origin Body draws the entire cultivation world into a frenzied hunt. Rogue cultivators, sect elders, and Nascent Soul monsters arrive one after another, while mysterious Abyss Keepers lay their plans in the shadows. Lin Mo meets Shen Yan, a companion who will face life and death by his side. As he evades the world's greedy eyes, he also pursues clues to the "Abyss," hoping to break the chains of fate imposed by his innate Origin Body once and for all.
The boy may look weak, but he holds the trump card of God Devouring. Fleeing is not the end. He will break free of his fate as a cultivation cauldron, defy heaven, change his destiny, and find a place where he can truly be safe. Scheming, battles, adventures, and bonds intertwine as we watch this young boy use his wits and strength to fight an entire cultivation world that covets him.
