Not only had Sisi left, but the time had also come to reseal the Sword Emperor's Tomb in the world.
This was an agenda that Zhao Changhe had proposed quite early on. The Sword Emperor's Tomb could not remain exposed indefinitely. Should anyone blunder into it and wake the Sword Emperor, that would be a thorough tragedy. Moreover, with the Maitreya Sect possibly rising up in rebellion, Gusu was the front line. If it fell into the Maitreya's hands one day, who knew how much trouble they could stir up?
Tang Wanju deeply agreed with this.
Lately, Sisi had been here to assist the Demon Suppression Department with this very task, investigating various spatial nodes to figure out how to conceal it again within an Otherworldly Space.
