In the Nine Heavens Profound Domain, martial souls reign supreme, and the lives of good-for-nothings are worth less than grass.
Lin Mo, a menial disciple of the Qingyun Sect, was born with a useless martial soul. After sixteen years of humiliation, at the moment he is near death, the ancient “All-Devouring Martial Soul” bursts forth from within him!
He swallows a Body Tempering Pill, and in an instant reaches the ninth level of Qi Refining. Then he devours an ordinary martial soul, grinding his good-for-nothing reputation to dust.
In the Scripture Pavilion, an inferior cultivation manual becomes the Devouring Heaven Art. In the sect's secret realm, the blood essence of a ferocious beast gives rise to a Heaven-Devouring Demon Wolf.
Rising from the mud of the menial disciples' quarters, he wins the outer-sect tournament and makes his name in the inner-sect trials. But his brilliance draws too much attention: framed by the young sect master, he devours his enemy's treasure and fights his way out of the Qingyun Sect!
He stumbles into the Valley of Ten Thousand Poisons, devours its miasma and poison pills, forges a body immune to all poisons, subdues the demonic beasts of the poison lands, and establishes the Spirit-Devouring Pavilion, making his first mark on the world.
He ventures into the Profound Domain's secret realm, devours divine weapons and absorbs rare treasures, mastering the supernatural arts of a hundred schools. At the young talents' tournament, he devours the martial souls of every prodigy, transforms into a Heaven-Devouring Python, and makes his name resound through the Nine Heavens.
When the Blood Demon Sect slaughters all living beings to refine evil pills, he leads the Pavilion's forces in a counterattack, devours the sect master's martial soul, reaches the Golden Core realm, transforms into a Kunpeng, and joins the righteous sects to crush the Blood Demon stronghold!
At the Sky-Piercing Tower, he devours its guardian divine beast, breaks through to the Nascent Soul realm, and ascends to the Upper Realm, only to discover that the Lower Realm is nothing but the Upper Realm's “farm,” where cultivators are raised as food!
“If the Upper Realm treats all living beings as straw dogs, then I'll tear down these Nine Heavens!”
He fights his way through the lowest reaches of the Upper Realm, devouring spiritual energy and devouring supreme treasures until his martial soul evolves into a Heaven-Devouring War God. He joins forces with ascendants from the Lower Realm and allies himself with righteous people of the Upper Realm, uncovering the earth-shattering secret that the gods cultivate by devouring souls!
He forms an alliance to slay the gods, devours divine artifacts and absorbs divine pills, breaks through to the Divine Realm, and battles the gods themselves, ultimately becoming the Lord of Chaos and Devouring!
He devours the Demon God and establishes a new order for the Three Realms.
