If this condition was presented by some ordinary sect, perhaps many would voice out their complaints and definitely not agree to it. After all, taking half of the said treasures for one's self is too over the board.

Anyone with a bit of brain would already know that it's not a good choice to offend something this terrifyingly powerful.
