As long as they could bring the Heavenly Cold Sect Saintess, Liu Qingqing, back to the Holy Land of Central State, they would have no worries about exchanging her for a Young Dragon.
By then, the Saint Heir would use Liu Qingqing as a cauldron to seize her Root Bone, and then exchange her for the Young Dragon. As for whether the Gu Family would go mad by then, that would be irrelevant.
After all, their Saint Heir's goal would have been achieved.
"Hmm?"
The two suddenly sensed something and simultaneously looked in one direction.
Before long, two other Ninth Grade Sages of the Annihilation Realm from Central State appeared beside Li Si.
"Now everyone is here."
Li Si greeted the two with a bow.
"Daoist Fellow Li, what do we need to do?"
The newcomers knew only that they were to follow Li Si's arrangements on the Saint Heir's orders, but they were not aware of the specifics.
