Dioxuan, a handyman of the Qingxu Sect, was bullied by his senior brothers and reprimanded by his elders because of his "attributeless spiritual root". Even his fiancée, who was married to his fingertips, broke off the engagement in public and became the laughing stock of the entire sect. When he was pushed down the sect's forbidden place "Meteor Spirit Abyss", he accidentally broke the ancestral jade pendant in his arms, awakening the sleeping soul-devouring ancient jade, and awakening the devouring physique.
He first devoured the poisonous grass and low-level monsters at the bottom of the abyss, broke through to the foundation-building realm in an instant, and tore apart the pursuing evil slaves of the sect with his bare hands. After returning to the sect, he devoured the spiritual power of the mockers in public, slapped the talented disciple "Zhao Yan" in the face, frightened away the snobbish elders, and took back the occupied resources.
In order to find out the truth about devouring the spirit body, Xuan Xuan wandered into the human world: devouring the weapons from the bandit's den to temper his body, swallowing the "Spirit Gathering Pearl" from the city lord's palace to advance to the golden elixir realm, and even devouring the inner elixir of ancient monsters in the secret realm to obtain the "Sky Burning Claw" magical power. The major forces in the human world were afraid of his abilities and joined forces to encircle and suppress him, but he stole the leader's magic weapon and became famous in one battle.
After breaking through the barrier of the realm, he devoured peach trees in the fairy world to increase his longevity, and in the demon world he swallowed the essence and blood of demon generals to master "Shadow Escape", gradually uncovering the secret that the spirit-eating body is actually the "balancer of the three realms" - it was banned back then because the immortals and demons were afraid of its balancing power. In the end, he devoured the "Chaos Demon Lord" who provoked the war in the three realms, merged with the origin of immortals and demons, broke through the realm barriers with the peak strength of the Tribulation Realm, penetrated the core of the disputes in the three realms, became the first "Spirit Devouring Supreme" in the Xuan Cang Realm, and reshaped the order of the three realms.
