Xu Nian followed the burly man towards Chen Nei.
Xu Nian was quite surprised by the strength of this burly man.
The black city tower was a full twenty meters high, yet when the man jumped down from it, he was unharmed.
This was enough to indicate that his physical strength was exceptionally strong.
Xu Nian himself couldn't achieve this.
As for his cultivation, Xu Nian couldn't discern it.
But he was sure it was definitely not below the Gang Tribulation Realm.
The Gang Tribulation Realm corresponds to the Transcendance Tribulation Stage of Spirit Cultivators.
Anyone who manages to cultivate their body to this level possesses extraordinarily terrifying physical strength.
Under the guidance of the burly man, Xu Nian entered this huge black city.
However, the population inside the black city was much sparser than he had imagined.
On the streets, there were only a few dozen people, and only a dozen soldiers stood on the city walls.
