"Indeed, they are all a bunch of sly creatures. One must not be careless, otherwise, he could have escaped."
Xu Yan nodded. These Remnant Souls, capable of surviving until now, were naturally not simple.
Fortunately, he was cautious enough to completely eliminate the other party.
In the Heavenly Cave Ruins, there were actually such Remnant Souls; surely someone had encountered them before, and might even have been beguiled by them.
Xu Yan surveyed the surroundings for a while, and after confirming there were no omissions, he continued with his exploration.
This Heavenly Cave Ruin was not very big, but it wasn't small either.
A meticulous exploration required several days to finish.
"Huh?"
Suddenly, he discovered a skull buried in the loose soil, which was even more eerie because it was blood-red in color, as if it had been dyed by fresh blood.
With a wave of his hand, the skull levitated.
"I've been waiting for you!"
