The light emitted from the stone door became brighter and brighter, completely enveloping Zhang Bin.
Then, Zhang Bin heard a crunching sound as the stone door opened by itself.
Revealing another stone chamber.
Zhang Bin hurried to take the Celestial Demon Technique, Part One, and rushed in eagerly.
He was dumbfounded. This stone chamber was the same as the one outside, empty with nothing inside.
There was only another stone door, with a dent similar to the previous one.
"Is someone playing tricks on me?"
Zhang Bin felt a bit frustrated, but he still put the Celestial Demon Technique, Part One into the dent immediately.
Sadly, this time it didn't work.
The stone door did not light up, nor did it open.
No reaction at all.
"Damn, it might require the Intermediate Volume of the Demon Tactic to open."
Zhang Bin's face turned drastically pale, jumping frantically, thinking he had stumbled upon a great secret, almost able to obtain the treasures inside.
