Blood.
That word immediately popped into Haike's dazed mind.
That puddle of dark red liquid that had suddenly appeared was undoubtedly blood!
And judging from its appearance and smell, it was most likely demon blood.
It belonged to a low-tier monster like him, too!
Once a monster reached the mid-tier, the concentration of demonic energy dissolved in its blood would increase exponentially, causing it to turn purplish or even black.
This puddle of blood was dark red, so the monster's overall strength probably was not much greater than Haike's.
And it had been injured for some unknown reason...
Even if he ran into it next, it probably would not pose any threat to him.
"Was that the shadow that flashed past earlier?"
Haike narrowed his eyes and sniffed hard.
Perhaps it was because of the environment, but the bloody smell was faint—far too faint for him to use it to pinpoint the other party's location.
However, the bloodstains on the ground were an excellent guide. They could help him track the other party, and they gave him an idea for finding a way out of the labyrinth.
Since the soft yet tough walls and floor could not retain any marks, he could use blood as a conspicuous marker instead.
Against the faintly glowing white walls, even a tiny amount would produce the desired marking effect perfectly.
"I hope that guy doesn't lose too much blood..."
Haike reached up and stroked the scar on his face, letting out a vicious grin as he muttered to himself.
He certainly did not say that because he was worried about the other party's condition or cared whether they lived or died.
He was worried that the monster would lose too much blood at once and drain itself dry, leaving him with nothing to use
