879 The Black-Robed Expert

A gentle wind was blowing through the Astral Islands.

Ji Ning was in an excellent mood today. He was flipping through his golden book when his face suddenly changed. "A challenge?"

Ever since he had risen to the fourth stratum, this was the first time someone else on the same stratum had sent him a challenge! The fourth stratum was just a single step away from the fifth stratum, causing everyone to be quite cautious and unwilling to casually start a duel against an unknown cultivator on the same level. They would first gather as much intelligence as possible before deciding whether or not to challenge the newcomer.

"He is actually one of the protected cultivators?" Ning frowned. "There are only around twenty protected cultivators in all the Astral Islands! All of them are unfathomably strong. For him to challenge me…"

"Wait. I'll wait for a short while." Ning shut his eyes and began to wait calmly.
