Su Yanzhi was once the most anticipated inner disciple of the Qingyun Sect, but due to an abnormality in his Dantian, he became a ridiculed "good-for-nothing". His fiancée broke off the engagement in public and was expelled from the sect. In a desperate situation, he unexpectedly awakened the dormant "Chaos Inkstone Heart Body" in his body and activated half of the remaining inkstone passed down from his ancestors - this inkstone turned out to be the "Hongmeng Inkstone", the natal magic weapon left by the ancient demon god. Using the essence and blood as the guide, and the demonic power as the ink, Su Yanzhi deduced the eternal skills in the inkstone, devouring the spiritual energy of heaven and earth, and turned the former good-for-nothing into a heaven-defying monster.
He subdued ancient ferocious beasts in the wilderness, gained ancient inheritance in the secret realm, stirred up the storm in the court, and crushed the sky between immortals and demons. The righteous path regards him as a heretic, the demonic path wants to refine him, and the demon clan regards him as their savior. Su Yanzhi holds an inkstone in his left hand to determine the universe, and a sword in his right hand to slay gods and demons. He fights back and slaps in the face all the way, gathering forces to reveal his shocking life experience as a "human-demon hybrid", as well as the secrets of the fall of the ancient demon gods and the broken barrier of the three realms. When evil spirits from outside the territory invaded in large numbers, he shouldered the heavy responsibility of guarding the three realms as a half-human and half-demon body, and finally became the inkstone and tripod demon god, making all races bow their heads.
