Compared to that, the shadow-space teleportation attack incorporating Emitter traits was simpler and more straightforward.
However, Moyu knew very well that the ability known as Shadow World possessed an enormous framework and system.
It was so vast that he did not dare plunge into it rashly. That would likely be like stepping into a swamp, sinking deep into incomparably heavy mud, unable to move forward even after exhausting every ounce of strength.
