From start to finish, neither guard had said anything. They didn't even show any emotions looking at Hao Xuan. Like he wasn't even there.
Judging from how they handled themselves and the looks in their eyes, Hao Xuan guessed, and rightly so, that they should have the same intelligence as that of a 16-18-year-old human. But as to their power, he was not able to see through it.
The guard on the left had pushed open the almost 8-meter thick metallic door like it was made of light wood so its physical prowess alone made it stronger than 70% of normal cultivators around the Spirit Realm. Only cultivators that had good physiques and constitutions would be able to go head to head with these guys using raw strength. Hao Xuan was, of course, one of these people.
