You Hongyi pointed at herself and asked in confusion, "Me?" She walked out of the range of the thousand-layered Restrictions and instinctively looked around. Everywhere she looked was a complete mess, and black smoke was rising from the other six peaks. Her expression darkened upon seeing this. She endured the pain from her injuries and cupped her fists slightly at Lu Zhou. "Ask away, old mister."

"Are you the current Grand Elder of Clarity Sect, You Hongyi?"

"Was the person you fought earlier Yu Zhenghai, the Sect Master of the Nether Sect?" Lu Zhou asked.

An expression of anger appeared on You Hongyi's face as she said, "Of course, I would recognize him even if he's reduced to ashes! My sect had thousands of cultivators, and yet, this is what we're reduced to! Please grant us justice, old mister!"

"You want me to grant you justice?" Lu Zhou did not know if he should laugh or cry even though his expression remained calm.
