Xu Fugui?
Did he come here before?

Mr. Su Bai didn't feel much tension or panic, especially considering that during the earlier "immersive experience," he had even encountered the First Emperor face-to-face and "personally" felt the emperor's imposing aura. Compared to that, the current situation seemed trivial in comparison—almost like aesthetic fatigue.
