In a cultivation clan, the weak are prey to the strong. Lin Yan is a lowly Five-Element spirit-root cultivator with such a mixed constitution that even drawing qi into his body is nearly impossible. In his clan, he is treated worse than an ant, enduring endless humiliation, his life worth no more than a blade of grass.
At death's door, with his blood staining an ancient jade heirloom, he accidentally awakens a fragment of an Immortal Venerable's soul that has lain dormant for ten thousand years: Ming.
The remnant soul coldly bestows upon him the forbidden inheritance, the Spirit Devouring Art, which defies all common sense: “A poor constitution? There is nothing under heaven that cannot be devoured! Pills, magical artifacts, spiritual energy, baleful energy, even an enemy cultivator's lifelong cultivation, and the blood essence and souls of demonic beasts can all become your ladder to the heavens!”
From then on, the cultivation world's most wretched good-for-nothing holds a double-edged sword thirsty for blood. He begins seizing what he needs where no one is watching, refining his body by devouring miasma and poison, and clinging to life by consuming trace amounts of spiritual energy as he stumbles along the edge of life and death. From turning the tables at a clan tournament to struggling to survive as a fugitive rogue cultivator, from snatching food from the jaws of danger in forbidden secret realms to boldly drawing his sword before the sect's prodigies, he will stop at nothing.
Devour, evolve, grow stronger. Hostility and pursuit follow him like shadows as he crosses mountains of corpses and seas of blood, rising from the Greenwood Realm to make a name for himself on the Canglan Continent and ascend through the Myriad Worlds. He devours tribulation lightning, consumes the laws of nature, refines space and time, and grows stronger through battle, defying heaven at every step.
Until one day, gods and demons throughout the heavens tremble before him, and the name of the forbidden resounds across the cosmos. Brushing the shards of tribulation lightning from the corner of his mouth, he gazes at the supreme laws of the firmament and murmurs with a smile:
“I hear… if you devour the Heavenly Dao, you can become a saint?”
This is a lonely road of blood, strewn with thorns and corpses. One man, one piece of jade, devouring the heavens.
