Within a millionth of a second after the four disappeared, five Celestials appeared in the room. There was a look of intrigue in their eyes as they scanned the room but could not detect any lingering traces from their teleportation, which was extremely unusual.
It had to be known that even if they themselves teleported somewhere, they would leave behind some traces that could be sensed or detected. Of course, if they planned far in advance and prepared meticulously, they could teleport somewhere without leaving any residual traces from the laws of space, but even that was conditional. Moreover, they were in the official peak realm of the Origin realm. How could someone in the Golden core compare to them?
The answer was simple. They couldn't. That left only one explanation for what had just occurred. The golden keys that Lex had handed out had been supreme treasures, the likes of which could not be easily procured.
