Long Yuehong switched positions from time to time and fired from the top, left, and right of the sandbag, not giving the mountain monsters a chance to approach.
Both sides hid behind their respective covers and exchanged shots.
Bai Chen and Han Wanghuo also joined in, but they didn't put all their attention on this. One took the opportunity to quietly remove a grenade and search for a suitable angle. The other observed the mountain monsters' activity patterns and slowly adjusted the muzzle's position, hoping to seize the opportunity to kill the enemy with one shot just as they were about to fire.
At this moment, an artillery shell landed outside the window and landed on the top of the collapsed building.
Boom!
A violent shockwave—mixed with crimson flames—surged into the windowless and glassless room, forcing Bai Chen, Han Wanghuo, and Long Yuehong to retreat to the fortifications and lay prone.
