The reason Chen Ge could think of that was due to Fang Yu. As Fang Yu grew older, her memory became worse.
"The monster's power should be related to memory. With the aid from the altar and the curse, his power gained some sort of improvement." Chen Ge found the key immediately. "All the curses in the room rushed toward the red high heels. So, it's clear that he knew his power is weakest on the red high heels, but why would the red high heels be immune to his power? Does this mean his power is a kind of curse itself?"
Regardless of the reason, Chen Ge knew that he could not allow this to drag on any longer. The man gave everything to protect the altar, so if Chen Ge wanted to turn this around, he had to target the altar.
"Xu Yin! Remove the altar from the man!"
