Harker's face turned ugly.
The Staff of the Earth's Core was one of the most important witchcraft tools of the Slavitt family. Not many people in the Slavitt family knew about its internal structure and use, but now, this stranger knew it like the back of his hand...
Harker narrowed his eyes, and the magic power surging in his body became more and more obvious.
The young man sneered and said, "You little thief who stole from Slavitt, do you think you can still walk out of this forest alive today?"
Harker said, "It seems that you really know what you shouldn't know. In that case... then stay here for me!"
At this point, he suddenly vibrated the strings of the harp.
Buzz! Buzz! Buzz!
Immediately, the heavy sound of the harp string exploded, and a material-like ripple appeared in the air, and spread out in the surroundings at the fastest speed.
