When the life-and-death crisis erupted intensely, Xu Qing didn't hesitate to put on the mask and crawled into the ground covered by flesh and blood, not moving at all.
His face tensed up and all traces of him were covered.
At the next instant, rumbling sounds echoed out as four terrifying energy fluctuations spread out, as though they were instinctively searching.
However, after Xu Qing put on the mask, as long as he didn't move, he could maintain a highly concealed state. Hence, in the perception of the four statues that only had instincts left, Xu Qing didn't exist.

This point was different from the statues they had seen in the few palaces they had been to before. This also showed how special this black square palace was.
