"The Sentinel Cannon is being built, please ......"

"Whoosh...... Rumble! Rumble!! Boom! In an instant, several huge explosions resounded throughout the prison! The flames of the explosion illuminated all corners of the prison and interrupted the system's report to Han Feng.

"What! Be...... What is it?! Standing up from the ground, Han Feng covered his ears with his hands and asked the system intermittently.

"Report to the commander, it's an RPG."

“R…… RPG？ What is it? Asking the system suspiciously, Han Feng rubbed his ears and felt much better.

"RPG bazooka. A bazooka is a portable anti-tank weapon that fires rockets, mainly rocket-piercing armor-piercing shells, but can also fire rocket-propelled grenades or other rockets, and is used to strike tanks, armored vehicles, infantry fighting vehicles, armored personnel transporters, military equipment and destroy fortifications at close range. The effective attack range is 300 meters, and it is the rocket armor-piercing projectile that was fired here just now......"

After listening to the system's answer, Han Feng shouted in his heart!

"Field of view connection!" Activating the radar's field of view connection function, Han Feng saw that his Red Alert soldiers were suffering heavy casualties...... The armor-piercing bullet has a penetrating effect, and even tens of mm of steel plates can be shot through, not to mention the walls of this building!

Blessings are incomparable, and disasters are not singular. Because of the explosion, Han Feng's arrangement was disrupted, and the other party's vanguard had already rushed into the building.

"System! Sentinel Cannon! Quick, has the Sentinel Cannon been built?! Han Feng asked eagerly, although his ears were buzzing at this time, he could still vaguely hear the sound of gunfire from the outside world. What puzzled him was that the unique sound of the sentry cannon did not sound for a long time.

"The Sentinel Cannon has not yet been built because it was interrupted during construction."

"Can it be built now? What is the impact of being interrupted? ”

"No, Commander."

"Then hurry up and build now! Entrance and exit of the building! Fast! After giving the order, Han Feng noticed a loophole in the system. I can't say that it is a vulnerability, it should be a weakness. That is, you can't be interrupted when you are summoning or asking to build, if you interrupt it......

"The Sentinel Cannon has been built."

"The Sentinel Cannon is activating ......"

"Bang bang bang!!" After a few seconds of introduction, the Vulcan cannons on the Sentinel Cannon fired at each other rapidly, and the accurate miniature shells pierced through a patrol before exploding.

The patrols on the first floor who were charging upstairs were confused by the sudden construction of the sentry cannon, but the confusion lasted only a few seconds before they were killed by the heavy fire.

The Sentinel Cannon began to work, and the powerful fire cut off enemy support from the outside. Now Han Feng is facing the patrol that has already rushed into the building and the rockets that don't know when they will attack again.

Sure enough, more than ten seconds after the last wave of rocket attacks, there was another "whoosh" sound in the air......

"! All of them! Circumvent! Find cover, quick! Han Feng knew that the rockets were coming, and in a hurry, he hurriedly informed everyone in his mind to dodge.

"Boom! Boom!! As soon as Han Feng's words fell, the sound of explosions suddenly rang out.

"System, modify the settings of the Sentinel Cannon! Attack bazooka launchers first! The disgraced Han Feng didn't have time to clean up the dust on his body, and urgently gave an order in his mind.

"The Sentinel Cannon setting is being revised, please ...... later"

"The Sentinel Cannon settings have been revised, now prioritize killing the Bazooka Launcher."

After listening to the system's reply, Han Feng breathed a sigh of relief. But the horror in my heart is not reduced by half.

The other side not only has assault rifles and grenades, but also powerful weapons such as bazookas!

It shouldn't be! It shouldn't be!

There are assault rifles in the prison that can still be said in the past, and there are grenades in the prison can barely explain it, but ...... There were bazookas in the prison?!! This can't exist anyway!

Why! Why?! Don't...... Could it be ...... There's an arsenal here too?!

For Han Feng, the equipment library is not unfamiliar. As early as a few days after the zombie outbreak, the police department's equipment arsenal refreshed his cognition.

An ordinary police station, with a large number of military assault rifles and grenades. This is also obviously unreasonable......

Thinking of this, Han Feng's heart instantly fell to the bottom.

If there's an arsenal here, then ...... Will there be a C quad bomb?!

In terms of power, the C-4 bomb is much higher than the high-explosive grenade.

And it's not just the C4 that may appear...... Will the sniper rifle be among them?!

Thinking of such a powerful long-range weapon, Han Feng felt like a man on his back.

"Report to the commander, the enemy has stormed the second floor."

！！！

"So fast?" Han Feng exclaimed.

It was only a few minutes before the charge, and the other party had already hit the second floor.

Listening to the bursts of gunfire coming from downstairs, Han Feng hurriedly asked Luna, "How many people are there on the second floor?" How many of us are there?! ”

"Report to the Commander, second floor...... Only three American GIs remained. So far, only 19 fighters remain on our side. ”

"Be more specific!"

"There were seven American GIs, twelve mobilized soldiers, and soldiers who were incapacitated were not counted."

After listening to Luna's report, Han Feng was silent......

From the beginning to the present, he has summoned nearly 50 Red Alert soldiers, and now...... Only 19 left!

"Such a high casualty rate......" After the low voice, Han Feng felt a little guilty to himself.

I thought that the other party of the rabble would not bring much hindrance to myself, but I didn't expect that the other party had such powerful weapons and equipment.

Such a miscalculation did bring a lot of losses to our side......

"How many enemies are there in the building?"

"Report to the commander, 36 people."

"I can't stand it, high-explosive grenades are ready! Beware of circumvention...... Try to survive. ”

Through the conversation with Luna, Han Feng knew that it was impossible for the three American GIs on the second floor to withstand so many patrols, so he had no choice but to order the three of them to make a final "suicide" attack through the radar.

"Boom! Boom! Three loud explosions rang out on the second floor, and the whole building trembled. Huge shock waves are superimposed on each other, reinforcing each other. It shattered most of the ceiling on the second floor!

Looking at the huge hole in the ground in front of him, Han Feng hurriedly asked Luna, "Has it been solved?" Did they survive? ”

"I'm sorry Commander, they're all dead with the enemy......" Luna reported the outcome of the attack with regret and apology.

"I don't blame you...... It can't be helped. Han Feng comforted Luna, but his hands were already clenched into fists. Listening to the "bang" sound of the sentry cannon coming from downstairs, Han Feng opened his mouth and said, "The rest of you, do a good job of defense and try to stay away from the window." ”

Han Feng didn't know if the other party had such a long-range weapon as a sniper snatch, but it was always a good thing to be careful.

One husband should be closed, and ten thousand people can't be opened! Downstairs, a sentry cannon guards the entrance and exit of the building, preventing the other party from entering.

Heavy artillery fire lasted for a minute, and each shot took away a single enemy life. Han Feng's "small vault" continued to grow at 20 or more per second.

Suddenly, the sound of firing downstairs became intermittent.

"What's the situation?" Hiding behind the bunker in the corridor, Han Feng asked suspiciously. In terms of time, the bullets of the Sentinel Cannon are far from being fired, so why is it not as fast as before?

"Report to the commander that most of the opposing side has withdrawn from the range of the Sentinel Cannon." After listening to Luna's explanation, Han Feng understood. It seems that the opponent's charge plan has failed, and at this time it is withdrawing from the range of the Sentinel Cannon.

Listening to the increasingly loose firing of the sentry cannon downstairs, Han Feng stopped talking, but just shifted his attention to the system. After these waves of battles, the gold coins at this time have accumulated to more than 5,000 again.

"5064 gold coins ......" silently meditating on the number of gold coins, Han Feng began to ponder.

5000 gold can be used to build a Sentinel Cannon, summon 10 American GIs, or summon 50 Mobilizers. But no matter what you do, there are pros and cons.

Building a Sentinel Cannon can reduce casualties, but it also has significant drawbacks. Not being able to move is the biggest problem, as long as the opponent is far away from the attack range of the sentry cannon, then the sentry cannon is an "ornament" and is very expensive......

But if you call American GIs or conscripts...... What if the other party has a sniper robbery? Besides, it's hard to guarantee that the other party will surprise yourself with a rocket!

After hesitating for a while, Han Feng finally made a decision.

Summons American GIs and Conscripts!

That's right, what Han Feng lacks most now is the personnel problem. Don't look at the entrance and exit of the building, there are sentinel guns, but it is only a one-sided defense, and it cannot be guarded in all directions.

On the back of the building, where the sentinel can't attack. When the enemy reacts, it's too late to run!

Of course, Han Feng also wanted to build a sentry cannon or machine gun bunker behind the building to defend it, but think about it carefully......

First: I can't keep guarding this building all the time.

Second: Although the construction of a large number of defensive buildings will ensure the safety of the moment, if you break through...... It's a bit stretched.

Third: The effective attack range of the machine gun bunker is only 120 meters, and it cannot kill the bazooka launcher......

Fourth: The moment when you break through is the time when you need personnel the most, rather than holding the sentry gun to the death, it is better to fight!

Just kill Viagra! It's relatively safe to be yourself.

"System, summon five American GIs, twenty mobilized soldiers! Confirm, be quick. Taking advantage of the fact that the deterrence of the sentry cannon was still there, and before the other party could react, Han Feng hurriedly ordered the system to summon the Red Alert soldiers.

"The system is calling, please wait."

Seeing that there were more than 700 gold coins left, Han Feng frowned.

"The gold coins are still not enough......" After saying this, Han Feng took out a cigarette from his pocket.

Looking at the cigarette slowly burning in his hand, it was as nervous as a countdown......
