"Is this... an Array Key?" Chu Youming, an Array Master from the Immortal Dynasty, looked at the red crystal stone in Su Youyi's hand with surprise.
"Array Key? Is it the key for this Great Formation?" Ying Xi thought of Su Youyi's ability to directly enter despite the formation, could it be because of this?
Su Youyi looked at the transparent fire-red crystal stone in her hand; she was hearing about the Array Key for the first time. Beside her, He Zhiqing and Yu Gejing also showed curious looks; they were also hearing about it for the first time.
"Array Key, Array Key, is generally a backdoor left by the Array Master, usually containing some rather secretive Array Patterns." Chu Youming took the Array Key from Su Youyi's hand, lifted it high, and looked at it obsessively. "It's rare for Array Masters to hand over the Array Key to outsiders; with this thing, I can break this formation in a short time!"
