Zhang Yan sat within the Demon Storage, circulating mana, attempting to refine the sealing of the Golden Seal, but despite using several Dharma techniques, he still could not break it.
He thought for a while, feeling that the most reliable and effective method was to simply use mana to gradually erode all the forbidden techniques through prolonged effort.
However, even if this method could be accomplished, it would likely take more than ten days, and what he lacked most now was time.
A great demon like the Taiheng Ancestor with thousands of years of experience had unfathomable strength and means. He didn't have much faith in Ying Chenglin and Zhang Boyant, fearing that it wouldn't take long after defeating these two before coming to pursue him.
Moreover, the ten strands of Earth Evil he possessed could only be stored for half a month, so it's best to return them to the Cave Mansion as early as possible.
