Ling Yun was once a rare cultivation wizard of the Qingyun Sect in a century. He was extremely talented and kind-hearted. He was regarded as the hope for the future of the righteous path. He studied under the master of the Qingyun Sect and was a brother-in-law with his senior brother Mo Chen and junior sister Su Qingyao. He carries the ancient secret treasure "Heart-Eroding Lock", but he does not know its true origin. He only thinks it is an ordinary protective magic weapon that he accidentally obtained when he was young. He has suppressed it with spiritual power all year round and has never revealed its power.
However, a well-planned "demon catastrophe" completely tore apart the hypocrisy of the righteous way. The Qingyun Sect united with the major righteous sects and set up a killing array on the grounds that "Ling Yun was carrying a magic weapon and colluding with the demons" in order to seize his heart-corroding lock and cover up the secret of the sect's senior leaders coveting ancient power and practicing forbidden techniques. Ling Yun was attacked by his most respected master, betrayed by his most trusted senior brother, and publicly accused by his devoted junior sister. All his meridians were cut off, his cultivation was ruined, and he fell into the devil's abyss.
When he was about to die, the Heart-Eroding Lock actively awakened and merged into his soul. He used his own essence and blood as a guide to repair his meridians and gave him domineering magic power. However, it also left behind the curse of "Heart-Eroding Pain" - every time he used his power, he would be eroded by the inner demon. Only by devouring the spiritual power and conscience of the hypocrite can the curse be suppressed.
Ling Yun, who climbed up from the devil's abyss, is no longer the innocent and righteous wizard, but has transformed into the cold demon lord Ling Ye, with only hatred and indifference in his eyes. He made an oath: to corrode his heart as proof, to slaughter all hypocrisy and righteousness, to level the gates of hypocrisy, to prove his true heart through the devil's path, and to make all those who betrayed him and harmed him pay the price with blood.
