At this moment, Blood Spider's strength was not sufficient to support her reckless firing of Space Mystical Arts crossbow bolts, and Bursting Crossbow Arrows were also very precious, requiring the modification by an advanced sub-profession skilled in engineering.
She could only fire them sparingly, for instance, inserting one Space Mystical Arts Bursting Crossbow Arrow amongst four to five ordinary crossbow bolts.
However, the power of the Space Mystical Arts Bursting Crossbow Arrow made the group of demons panic and tremble.
None of them knew whether the next crossbow bolt fired would be an ordinary one or a terrifying bolt with formidable power, capable of exploding inside their bodies!
Even one of the three Demon Marshals, Shark Teeth, after taking a hit from one of Blood Spider's Space Mystical Arts Bursting Crossbow Arrows, had a bloody wound blown open on his abdomen, suffering over 400 points of damage.
It roared angrily and charged towards Blood Spider in big strides.
