Feeling the sword edge so close, Hu Xiao instinctively swallowed a mouthful of saliva.
The last time he felt such intense killing intent from Su Chengyu was in that swamp, the moment he himself first exposed his killing intent towards Su Chengyu.
He couldn't comprehend how Su Chengyu saw through his façade, realizing that his previous strike was not a mistake, but a deliberate act.
The urge to deny and counter was swallowed up under this intense killing intent, and he dared not speak it.
Facing an obviously different attitude from Su Chengyu, Hu Xiao finally just said.
"Master, I understand..."
Not daring to deny, much less to admit, Hu Xiao had no courage to argue under Su Chengyu's questioning at this moment.
He strongly suspected that if he did anything else to displease Su Chengyu now, Su Chengyu would take action against him without hesitation.
"How did you break through the bottleneck and reach the Demon Emperor Realm?"
