Mirage Shadow stood outside the closed door of Ace's room, maintaining the sealed barrier. Although she was curious, she didn't dare to peek inside, and was extremely vigilant as if she was protecting the Dread Duchess.
On the other hand, the guards of the Khazar's castle couldn't detect anything because they weren't at Mirage Shadow's level, not to mention even a Grand Lord would have difficulty sensing Mirage Shadow's presence!
At this moment, the closed door suddenly opened, and Ace walked out under Mirage Shadow's startled look.
As for how Ace walked out of her barrier, its purpose was to seal outsiders from entering, and it wouldn't stop those who wanted to come out. Zaria evaluated the barrier's nature, having seen a similar one in the past.
Ace, without waiting for Mirage Shadow's reaction, curtly said, "Thank you for your trouble, senior. Let's go, we are done here. Oh, and don't put down this barrier for at least five minutes if possible."
