With Bai Huo leading the way, Hao Ren and the others headed toward the "Tower" of Stars. A ring of black rocks floated around the entrance to the enormous cavern. Each rock held a Demon Hunter with a stern expression. As they passed the floating rocks, Bai Huo quietly explained, "They're the Night Vow of the Tower of Stars, sworn to the Midnight Vow. Their duty is to guard the tower's entrance forever. If our stronghold ever falls, they'll activate the Magic Stones beneath their feet and blast the entire tower into twisted space, so no outsiders can enter the holy land of Corpus. But things are unpredictable... Who could have imagined that one day the threat would come from within Corpus? Now they're ready to blow up the gates here at any moment, but this time it's to keep the Elder Council inside the holy land from getting out."
Lily's ears twitched, and she immediately regarded the stern-faced sentries standing on the Magic Stones with newfound respect. Her voice was full of amazement. "They have to stand on those rocks for their whole lives?! And they're not allowed to get down?! Good heavens... What kind of willpower would that take..."
Bai Huo was even more surprised than Lily. "Of course they're allowed down! They work in three shifts..."
Even Hao Ren was dumbfounded this time. "...Uh, didn't you say they guard the tower entrance forever or something?"
Bai Huo frowned. "I mean they can't be transferred to another post. These Magic Stones are very delicate, and to prevent accidents, they're tuned to the Night Vow's mental frequencies. It's very difficult to train a qualified guard, so transfers aren't allowed. Why do you people always have such strange ideas?"
Hao Ren opened his mouth, but couldn't get a word out.
