After confirming that the Three Witches had divulged all that they knew, Wei Yuan fed them to the Sea Grass.
Having just consumed two Great Witches, receiving three little witches resembled dessert after a meal, and while the Sea Grass seemed pleased, it only sprouted a single new branch.
Certainly, the environment of Mortal World wasn't suitable for the Witch Clan's survival; even without being fed to the Sea Grass or tortured, the Three Witches wouldn't survive more than a few hours.
Wei Yuan then turned his gaze to the small island formed from the Netherworld Soil. Currently, the environment of the island was about sixty to seventy percent similar to the You Han Realm. If the captured witches were placed on this island, they might survive a bit longer.
