With the robot tiger's decoy firepower, the enemy's rapid-fire gun position was exposed, and two snipers took position and fired at the rapid-fire gun.

Two crisp gunshots rang out, and bullets flew out like lightning, accurately hitting a rapid-fire cannon, and sparks instantly burst out of the cannon barrel.

Using a sniper rifle to fire a rapid-fire cannon sounds exaggerated, but if the bullet is fluoroantimonic acid, then it is a different matter.

At this time, fluoroantimonic acid was accurately poured onto the barrel, and pungent smoke instantly rose.

Under the strong corrosion of fluoroantimonic acid, the barrel quickly became riddled with holes, and the originally solid metal surface began to dissolve, leaving deep grooves.

The acid flowed down the barrel, corroding everything it touched. The paint on the barrel peeled off and the metal parts became rusty and brittle.

In the end, the rapid-fire gun misfired and completely lost its combat capability.

"Boss, it's bad, our rapid-fire cannon is under attack!" In the command room, the fault light came on and at the same time the prison guard exclaimed.

"You bunch of bastards, I'll call the special police for support, you guys drive the infantry fighting vehicles out." Commons said with a somewhat unnatural expression.

"Hello~ Is this the old director? I'm Constantine. My prison has been attacked. Please inform the new director. I need special police support. The more people the better." Commons said with a heavy breath.

"What's going on?" asked the retired director in disbelief.

"Old Director, the matter is urgent. I will explain it to you later. Please help me first. The people who attacked me are well-equipped. This is the first time I have encountered such a situation! There are about sixty of them." Commons said anxiously.

If Commons was confident that he could defeat the enemy at the beginning, he felt something was wrong after the exchange of fire.

If he used his conventional weapons against thugs, it would be a one-sided massacre. But when he met this group of people tonight, he felt the pressure before they even had a head-on collision.

"Okay, I got it. Wait for my news." The old director stopped talking nonsense.
