86. Blood Trail
Mack pondered for a few seconds why the rune circuit was not working, and quickly came with a plausible answer.
"Right, I'm on Earth. The Essence here is lower."
Said Mack, already drawing a new circuit that not used the essence from the environment but from an essence crystal.
Finishing the drawing, Mack took an essence crystal from his backpack and put over the rune circuit and pressed his thumb.
For Mack, the good thing about essence crystals is that they could be used multiple times if the essence used was low, because he had only a few of them remaining.
The runespell activated, and Mack saw a small line of blood trembling intensely in the circuit.
It was the direction he had to follow, and by the frequency it was trembling, Mack knew it was close.
Mack deactivated the runespell, put the essence crystal in his backpack, and walked in the direction the rune circuit told.
