Xu Ping'an entered the Space-Time Gate and arrived within a cluster of palaces.
And these palaces felt very familiar to him.
"Is this the Holy Heavenly Sect?" Xu Ping'an looked at the cluster of palaces in astonishment.
The architecture of these palaces was exactly what he had seen in the ruins of the Holy Heavenly Sect.
However, the palaces here were newer.
Moreover, it seemed there were many people moving about within the sect, all wearing the same attire.
Among these people, besides humans, there were also many upright-walking Demon Beasts.
"Is this the time when the Holy Heavenly Sect still existed? Have I come to 180,000 years ago?" Xu Ping'an marveled inwardly.
He glanced around and realized this was indeed the Immortal Realm of the past.
The Immortal Qi was extremely rich, much denser than in the Spirit Realm.
But he was unable to absorb it.
Not only that, he discovered that these people also couldn't see him, and he couldn't touch them.
