"If there is a secret about this fan, it should be the cave mansion in this painting. But it seems to be just a picture. The cave mansion doesn't seem particularly unusual." Zhang Bin channeled his spiritual power to carefully sense and observe. This time, he felt more clearly that his spiritual power still couldn't enter the gate of the cave mansion, nor penetrate deep into the material of the fan, likely indicating the cave mansion doesn't exist and is just a drawing.
"Perhaps this fan isn't the one Tyrant Demon Emperor asked Mo Yi to find, but another one," Zhang Bin muttered. "But either way, I should avoid using this fan recklessly in battles. If it is indeed the one, I can't let others see it. Wealth should not be exposed. Additionally, I need to think of a way to study this fan in the future and find other ancient fans on Earth."
After spending more time observing and studying it carefully, Zhang Bin still found nothing else.
He had no choice but to put the fan away.
