A hidden paradise?
Xu Ping'an was somewhat astonished; he hadn't expected a hidden cave to exist behind the waterfall.
The flow of the waterfall was too strong to be observed with the naked eye.
Moreover, with the thick poison miasma here, ordinary cultivators wouldn't dare to use their Soul Power to explore, so it was basically impossible to be discovered by anyone.
"As expected of the Heavenly Star Palace, opportunities are hidden in every corner, but this cave seems to contain an extremely powerful Killing Formation," Xu Ping'an thought to himself.
If it was a place that Cang Xue had reminded him of, it must be anything but simple.
"Senior Cang Xue, how strong is this Killing Formation?" Xu Ping'an asked.
"It can kill a Ninth Rank at the Initial Stage, and for an Eighth Rank, it's almost certain death," Cang Xue replied.
"That strong? Wouldn't I be dead for sure if I went in?" Xu Ping'an exclaimed in surprise.
