'Hmm?'
Hong Yu had slain over a hundred Desolate Beasts, and the number of stars on his Luo Rune Seal had reached three hundred.
However, that was still a long way from the full eighteen thousand stars.
But the power of the Luo Rune Seal had clearly increased significantly.
Just as he was preparing to leave, he subconsciously swept his gaze across the valley with his Illusory Spirit Celestial Eyes and suddenly noticed something strange.
'These Desolate Beasts seem a bit different!'
Using his Illusory Spirit Celestial Eyes for Peeping Essence, Hong Yu discovered that the bodies of these Desolate Beasts were much tougher than ordinary ones.
The Luo Rune Seal killed Desolate Beasts by draining their essence, but it didn't cause much damage to their physical bodies, so Hong Yu could still examine the corpses.
He casually cut open the body of one of the Desolate Beast corpses.
