That little green monster was like a reaper stalking the dark fringes of Skeleton Mountain.
Its purpose was to kill every outsider who intruded upon Skeleton Mountain.
The reason it hadn't attacked Tu Xiao'an openly was that it must have sensed he would be a tough opponent.
A supreme expert.
That was why it had used Song Ao's body to launch a sneak attack on Tu Xiao'an.
But against the War Kings from the Demon Management Bureau, it didn't need to be so cautious. It could just strike directly.
The corpses before him told Tu Xiao'an that the little monster was definitely still hiding nearby, perhaps watching him like a tiger stalking its prey.
It probably wouldn't let him go. It was surely biding its time, looking for the chance to kill him with a single, fatal blow.
Tu Xiao'an silently surmised this as he scanned his surroundings with a frigid expression, a red glow flickering in his cold, bewitching eyes.
