Gu Qing Shan's inner sight scanned the golden scepter.
At the point where the skull used to be connected to the scepter, the metal was cut clean enough that it's still shiny. Clearly it was carefully cut with a very sharp tool.
-------who would leave behind a pure gold scepter just to steal a dead man's skull?
The sense of unease Gu Qing Shan had from before was becoming stronger and stronger.
Even without the Emperor as the most formidable fighting power, the palace's tight defense still wasn't anything to joke about.
Unless you're a world-class powerhouse, you aren't going to be able to sneak into the palace.
Not to mention, you would also have to know the entire layout of the palace defenses, avoid being detected by the powerful Emperor AND know where the Empress kept these items.
Of all the world-class powerhouses, who would spend so much effort specifically just to steal the Fuxi Empire's first Emperor's skull?
