Xu Yi reached for the door, but just as he was about to push, a sudden sense of alarm made him snatch his hand back.
In that instant, he had distinctly felt a strange fluctuation of magic coming from the door.
Someone had actually placed a magic array on this perfectly ordinary door!
If Xu Yi had kept pushing, he would certainly have triggered it.
Xu Yi considered this for a moment, then reached out again.
His fingertips lightly touched the door, and he released a faint thread of magic through them, tracing the magic array on the door bit by bit.

Once triggered, this magic array would unleash a powerful blast of air.
Although a third-tier magic array was not particularly powerful, and even a direct hit from its blast would not kill anyone, the Windburst Array could send a person flying. Even if they survived, they would certainly be injured.

But this was the Royal Palace, after all. How long could they keep
