Jun Wu Xiao stared intently at the monster's core. Aside from its black color, he felt nothing unusual about it. He thought to himself:
"From what I've witnessed, it's almost certain that the monster core is an energy source. When I removed it, the entire body of the monster gradually disintegrated as if it had run out of energy. But how exactly does this energy work? This orb just looks like a black stone with nothing special about it. Maybe I should try burning it."
He hurried outside, gathered some wood, and started a fire. As the flames roared, Jun Wu Xiao tossed the monster core into the blaze.
Suddenly, he clutched his forehead and muttered:
"Damn it, am I stupid? Explosives couldn't even scratch it before, so what could a low-temperature fire do?"
With that, he extinguished the fire, retrieved the core, and returned it to its original spot. This time, he rearranged the stones to block the cave entrance more securely, ensuring it wouldn't collapse as easily as before.
