The reason why Zhou Zhou said that this transaction was not for forever was mainly because the Dragon Transformation Pool could transform wyverns into pure-blooded dragons. Most importantly, it contained the precious Dragon Transformation Pool.
The creation of the Dragon Transformation Pool required a large number of God-Tier materials, as well as the blood of pure-blooded dragons and the dragon souls of pure-blooded dragons, which were at least Low-Tier Deity Level Elementary Grade.
The former was nothing. Zhou Zhou's Dragon God Army could provide it at any time.
However, the pure-blooded dragon soul was different.
Zhou Zhou had yet to find a resource channel that could continuously produce pure-blooded dragon souls.
