This is a small object called an Image Capturing Pearl!
By injecting True Qi, it can trigger the arc inside, recording the surrounding scenes, and can generally record for up to a quarter of an hour at a time!
Zhao Quanzhen used this object, taking advantage of the chaos to cast it out, recording the scenes inside the large formation, but unexpectedly, there was a Great Demon overseeing inside the formation, and his actions were detected by this Great Demon, leading to the current situation.
Fortunately, he had the Dust-Repelling Robe given by Master Yangshan for protection, blocking the attack of this Demon, allowing him to escape.
