As for those with high cultivation, several Void Refining Peak and late-stage practitioners were still alive, but the rest, including Young Master Qi and Taoist Bai He, were imprisoned in some small world.
He planned to keep these people to serve as nourishment for his Demon Suppression Tower.
Once the "Demon Suppression Tower" was placed somewhere, it could no longer be removed. He originally wanted to place it within the small world of the Chao Tian Sect, but now it was clear that, at least for a short time, within a year, he would not be able to enter the small world.
It wouldn't do to have the Demon Suppression Tower just sit there, unused, for a year.
Thus, he planned to install the Demon Suppression Tower inside the Heavenly Palace. The space in the Heavenly Palace was large enough; after all, it could accommodate those dozens of sculptures tens of meters high, so it could certainly fit a Demon Suppression Tower.
