Misty Zone, southwest edge of Huiqiu Mine, within an abandoned mine tunnel.
The two most elite groups of the city's guards were encircling a newly discovered rebel camp. This was the fourth camp they had found, and based on its location at the very bottom of the mine shaft, it was likely to be the last.
The barrage of gunfire echoed back and forth through the narrow corridor, a tremendous ordeal for everyone's ears, and the rebels' counterattack was especially tenacious. The guards had organized several assaults but had been repelled each time.
——Indeed, the enemy was also equipped with firearms.
Heaven knows where they got these weapons from.
"Watch out, grenades!" someone shouted.
What followed was an earth-shattering roar! A bright fireball lit up the tunnel like daylight, but only a second later, the flames were replaced by a cloud of black smoke. The scorching blast caused countless fragments of rock to clutter and crackle.
