Ace remained in the crowd, his expression calm, yet inwardly his vigilance had already reached its peak.
Just a moment ago, Ace felt a terrifyingly profound power sweeping past him, and it almost made his mirror embryo shatter!
If not for using all the Darkness Force to barely hold his mirror persona, he would've been exposed, and he didn't dare to imagine the consequences afterward.
Although Ace had no idea what kind of power that was, or who it belonged to, he was sure that it was the Evernight Kings doing so, probably to ensure nothing unknown had infiltrated the Evernight Sanctuary from the Undead Cradle.
Moreover, Ace noticed that none of the other participants were aware of that mysterious power's presence, and they all remained the same.
But what made Ace's heart almost stop was that power; after sweeping over him once, it came back again, and this time it lingered on him for a moment longer before vanishing again.
