At that moment, Shun Long, Liu Mei, Jiang Chen, and Bai Longtian, all saw a silver-colored pendant on the crown prince's neck that was shining with a bright silver light, as it slowly turned into dust.
It was obvious that the pendant on his neck was a protective artifact that could protect the crown prince's life when he was in danger, similar to the pendant that Liu Mei had received from Elder Xuan when she accepted her as a disciple.
However, unlike Liu Mei's pendant, the crown prince's pendant could only be activated once before it lost its power, and the power behind it wasn't anywhere close to Liu Mei's that could protect her even from the attacks of a late-stage Dao Emperor.
Naturally, although it could only be activated once, its value couldn't be measured with spirit stones as it had successfully saved the crown prince's life before it repelled Xingyi away, even managing to injure her in the process.
