"It seems to be better than the spirit of fire."

He once obtained a similar item after killing the fire giant in Pyeongtaek.

He loaded it on the repeating crossbow to add the 'ignition' function.

Right at that moment, there was a violent vibration in the ground.

Googoogoooo-

"Vibration?"

Sungwoo looked around. However, no phenomenon could cause vibration anywhere.

Googoogoogoo-

At that moment, he suddenly looked down at his feet. Concrete debris trembled and rolled back and forth. The vibration was coming up from deep underground.

Sungwoo was familiar with this kind of vibration, something coming up steadily and very slowly from a very deep place underground.

The middle of the rubble piled up like a mountain began to sink because of a large hole under it.

'Sinkhole?'
