Alien Race! These two words flashed through Li Yuan's mind instantly.
Li Yuan had thought about this issue, that only by killing members of the Alien Race could one obtain spiritual nourishment.
Then, could he use Divine Palace Inquiry to identify members of the Alien Race lurking inside civilization?
Li Yuan had only heard of spies from the Alien Race.
Since his spiritual power broke through level 20, the burden of performing Divine Palace Inquiry had lessened a lot, and he had formed the habit of using it on any significant individuals he met.
It was a pity that he had never encountered an Alien Race spy all this while.
