The heavens and myriad realms all concluded that he cut off the immortal path, slaughtered immortal gates, and wreaked havoc on all living beings, making him a great demon king whom everyone had the right to punish and kill. Yet facing his disciples' hatred and the world's judgment, Xiao Fan did not defend himself; instead, as if he had long been waiting for this day, he was intent on meeting death.

But the past reflected by the Haotian Mirror step by step overthrew everyone's cognition.
