Gu Qing Shan didn't stay long in the barren land.
Since the decisive battle was approaching, he was facing immense pressure.
And since he told Luo Bing Li just earlier that he needed to resolve a problem in his cultivation, it wasn't a good idea to leave right away.
So he made his decision.
He was going to check the Cruel Bone Devil King's corpse and confirm this unlucky evil creature's identity.
In the small chance that this Cruel Bone Devil King was also an impersonator, there would have been two fake Cruel Bone Devil Kings in this world and all of my assumptions would be incorrect.
Of course, the chances for this were close to zero.
But before checking the corpse, any number of possibilities were still possible, so Gu Qing Shan decided to check it out anyway.
He wanted to make sure that all of his assumptions and conjectures were concluded from reasonable foundations that actually existed.
