Lu Xiao paid no mind to Chen Lin's taunts.
Having reached his level of cultivation, his skin was as thick as a city wall, or close enough. Letting spit dry on his face without wiping it off was a trivial matter.
But he could not guarantee that his fallback would exempt him from the punishment for failing the mission. Since Chen Lin was willing to try his hand on the arena, he naturally had to offer some support.
After a moment's thought, he took out a scroll.
He stroked it reluctantly, then handed it to Chen Lin.
"This is also a Nightmare Treasure. I obtained it only after escaping death by a hair. It contains the sealed mouth of a terrifying Nightmare Realm creature, and it will activate automatically when the scroll is unfurled."
Then he cautioned, "Fellow Daoist Chen, be careful. Once activated, it will attack the living being nearest to it. If it successfully devours its target, it will return to the scroll. If it fails, it will attack the next nearest one. You must choose your moment carefully when using it, lest you fail to strike your enemy and sacrifice yourself instead!"
With a look of surprise, Chen Lin took the scroll.
If Lu Xiao's explanation was accurate, this thing was best used to ambush people. Anyone who unknowingly inspected it as a treasure would fall victim immediately.
To think the Nightmare Realm contained something so peculiar. He silently marveled at it.
He probed it, but sensed only an obscure fluctuation within the scroll and could not ascertain its true condition.
Still, it served as a reminder that he would have to be doubly careful when inspecting scroll-like objects in the future.
"How can I verify whether what you said is true?"
Chen Lin dispensed with pleasantries
