He had already died in the Nine Layers of Earth Fire in the Dark Abyss Hell, and he blamed him for being so cruel to him.
You destroyed my sect and slaughtered all the members of my Shenghua sect. Now you torture me, kill me, and imprison my soul until I am reduced to ashes. Can't you let me go?
He was rescued by him when he was young, and he thought he would be the person he was most grateful to, but he was abused by him until he escaped from Shenghuamen. He hated the man who gave him hope and then plunged him into a bottomless abyss. Because of hatred, he awakened the demon bloodline, and he unified the demon world step by step. He became the most powerful demon in the six realms.
Then he repeated all the humiliation, abuse, and cruelty he had inflicted on him. He killed his body and imprisoned his soul in the coldest and darkest hell, watching him suffer tortures that were ten times and a hundred times more severe than what he had endured.
He smiled, "So it's me who caused all this?" He burned his soul on fire, thinking that it would end everything, but he didn't expect that this was the beginning of everything. When he opened his eyes again, he became the junior disciple of the respected head of the Shenghua Sect again. Everything started again. He began to worry, should he save the future Demon Lord like he did in the previous life?
