A mere Heavenly Monarch, could he really return after entering the land of Immortal Weeping?
The land of Immortal Weeping is forbidden territory; with Cheng Xiong's strength at that time, it was simply impossible for him to qualify for entry!
If you think about it that way, then someone must have paid a certain price for Cheng Xiong to do something for them and then handed him this treacherous method afterward.
By the same token, if a member of the Li Family was practicing this method, with the Li Family's strength, they couldn't possibly have someone capable of entering the land of Immortal Weeping either.
Zhuge Xiang was able to enter the land of Immortal Weeping only because the old man gave him a back door; otherwise, with that old youngster's strength, he wouldn't be able to enter even if he trained for another hundred years.
