"Boom!"
"Boom!"
A massive explosion sounded as the thermobaric rockets detonated within the tunnel.
The searing flames instantly consumed much of the air in the tunnel, and the intense negative pressure surged inward, creating a fierce airflow.
Drone No. 1 has already been destroyed, leaving Chen Jian without means to observe the situation inside the tunnel.
However, it was evident that the rocket explosions also slowed the enemy's advance inside the tunnel, buying them new suppression time.
"Fire!"
Chen Jian shouted, issuing the order to Li Shi, almost simultaneously with the heavy machine gun in his opponent's hands going off.
"Bang bang bang bang----"
The tracer bullets flew into the tunnel like swarms of dancing fireflies.
Immediately after, the projectiles struck the tunnel walls, erupting in brilliant sparks one after another.
"Guo Xu!"
"Detonate the other two explosive entries!"
"Understood!"
