First Challenge

It had been three hours since Alex began roaming the labyrinth, and he had dealt with both adventurers and tomb guardians, but none of the encounters were worth mentioning besides the first one.

The three-star tomb general had been a real challenge, as besides his superhuman strength, agility, and senses, and the ability to morph into a bat-like creature with deadly fangs and sharp claws, he wielded sound magic and necromancy. 

The biggest challenge in dealing with him was his ability to regenerate at an extreme speed, as he could use his own vitality to regenerate even lost limbs. Even when Alex decapitated him, he stayed alive, only dying once he crushed his head into meat pulp.

Alex was moving through the winding passage toward the center of the labyrinth when he sensed the disturbance in space a few meters behind him, so he halted his steps and turned around, expecting a tomb guard to appear because this was his second time seeing this phenomenon occur.
