"The sentry guns are being built, please..."

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

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

"Report Commander, it's RPG."

"R... RPG? What is it?" Han Feng asked the system doubtfully, rubbing his ears and feeling much better.

"RPG rocket launcher. The rocket launcher is a portable anti-tank weapon that launches rocket grenades. It mainly launches rocket armor-piercing grenades. It can also launch rocket grenades or other rocket grenades. It is used to attack tanks, armored vehicles, and infantry fighting vehicles at close range.

Armored personnel carriers, military equipment and destroyed fortifications. The effective attack range is 300 meters. What was fired here just now was the rocket armor-piercing projectile..."

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

"Vision connection!" When the radar's vision connection function was activated, Han Feng saw that his red alert soldiers suffered heavy casualties... The armor-piercing bullets have a penetrating effect and can penetrate even tens of mm of steel plates, let alone the building's

The wall is up!

Good luck never comes in pairs, but misfortune never comes alone. Because of the explosion, Han Feng's arrangement was disrupted, and the opponent's vanguard troops had already rushed into the building.

"System! Sentry gun! Quick, have the sentry guns been built yet?!" Han Feng asked eagerly. Although his ears were buzzing at the moment, he could still vaguely hear the sound of gunfire from the outside world. This made him confused.

Yes, the unique firing sound of the sentry gun has not been heard for a long time.

"The sentry gun has not been completed yet because it was interrupted during the construction process."

"Can we build it now? Is there any impact if it is interrupted?"

"No, Commander."

"Then hurry up and build it now! The entrance and exit of the building! Hurry!" After giving the order, Han Feng noticed a loophole in the system. I can't say it is a loophole, it should be a weakness. That is, he cannot be interrupted when summoning or requesting construction.

Yes, if interrupted...

"The sentry gun has been constructed."

"The sentry guns are being activated..."

"Bang bang bang bang!!" After a few seconds of introduction, the Vulcan cannons mounted on the sentry guns fired at each other rapidly. The precise micro-shells penetrated each patrol team and finally exploded.

The patrols on the first floor who were charging upstairs were a little confused by the suddenly built sentry cannon, but the confusion only lasted for a few seconds before they were killed by the fierce firepower.

The sentry gun started working, and the powerful firepower cut off the enemy support from the outside. Now Han Feng faced the patrol team that had rushed into the building and the rockets that did not know when they would attack again.

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

"Damn it! Everyone! Avoid it! Find cover, quickly!" Han Feng knew that the rockets were coming, and he hurriedly told everyone in his mind to take shelter.

"Boom! Boom!" As soon as Han Feng finished speaking, explosions suddenly broke out.

"System, modify the settings of the sentry gun! Prioritize attacking the rocket launcher!" The disgraced Han Feng had no time to clean up the dust on his body and urgently issued orders in his mind.

"The sentry gun settings are being modified, please wait..."

"The sentry gun settings have been modified. Now priority is given to killing the rocket launcher."

After hearing the system's reply, Han Feng breathed a sigh of relief. But

The shock in my heart did not diminish by half.

The opponent not only has assault rifles and grenades, but also powerful weapons like rocket launchers!

It shouldn’t be! It shouldn’t be!

It can be said that there are assault rifles in the prison, and it can be explained that there are grenades in the prison, but... there are rocket launchers in the prison?!! This is impossible in any case!

Why! Why?! Could it be that...could it be said that...there is also an equipment warehouse here?!

For Han Feng, the equipment warehouse is not unfamiliar. As early as a few days after the zombie outbreak, the police station's equipment warehouse refreshed his knowledge.

An ordinary police station actually has a large number of military assault rifles and grenades. This is obviously against common sense...

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

If there really is an equipment warehouse here, then...will there be C-4 bombs?!

In terms of power, C-4 bombs are much higher than high-explosive grenades.

And not only C-4 may appear...will sniper rifles be among them?!

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

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

!!!

"So fast?" Han Feng exclaimed.

It was only a few minutes before the charge started, and the opponent had already reached the second floor.

Listening to the bursts of gunfire coming from downstairs, Han Feng quickly asked Xiang Luna: "How many people are there on the second floor? How many people do we have?!"

"Reporting to the commander, there are only three American soldiers left on the second floor. So far, we only have 19 combatants left."

“Be more specific!”

"There are seven American soldiers and 12 mobilized soldiers. Soldiers who have lost the ability to fight are not included."

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

From the beginning to now, I have summoned nearly 50 Red Alert soldiers, but now... there are only 19 left!

"Such a high casualty rate..." After whispering, Han Feng felt a little guilty.

I thought that the ragtag opponent would not bring much hindrance to me, but I didn't expect that the opponent had such powerful weapons and equipment.

Such calculation errors did bring considerable losses to our side...

"How many enemy people entered the building?"

"Report to Commander, 36 people."

"I can't stand it anymore, prepare high-explosive grenades! Pay attention to avoidance... try to survive."

Through the conversation with Luna, Han Feng knew that the three American soldiers on the second floor could not withstand so many patrols, so he had no choice but to remotely order the three men to carry out a final "suicide" attack through the radar.

"Boom! Boom!" Three huge explosions sounded on the second floor, and the whole building trembled. The huge shock waves superimposed on each other and strengthened each other. It actually 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? Have they survived?"

"I'm sorry, Commander, they died together with the enemy..." Luna reported the results of the attack with a regretful and apologetic voice.

"It's not your fault... there's nothing we can do about it." Han Feng comforted Luna, but his hands had already been clenched into fists. Hearing the "bang bang" sound of the sentry cannon coming from downstairs, Han Feng said: "

The rest of the people, take precautions and stay away from windows as much as possible."

Han Feng didn't know whether the opponent had such long-range weapons for sniping, but it was always a good thing to be careful.

One man is a guard against ten thousand men! Downstairs, a sentry gun guards the entrance and exit of this building, preventing the other party from entering.

The fierce artillery fire lasted for a minute, and each shot took away one of the enemy's lives. Han Feng's "little treasury" continued to grow at a rate of 20 or more per second.

Suddenly, the sound of fire downstairs became intermittent.

"What's going on?" Hiding behind the bunker in the corridor, Han Feng asked doubtfully. According to time calculation, the bullets of the sentry gun were far from being fired, so why didn't it fire as fast as before?

"Report to the commander, most of the opponent's people have withdrawn from the attack range of the sentry gun." After listening to Luna's explanation, Han Feng understood. It seems that the opponent's charge plan has failed, and they are currently withdrawing from the attack range of the sentry gun.

Listening to the increasingly sparse firing of the sentry guns downstairs, Han Feng stopped talking and just turned his attention to the system. After these waves of battles, the gold coins at this time had once again accumulated to more than 5,000.

"5064 gold coins..." Silently reciting the number of gold coins, Han Feng began to think deeply.

5,000 gold coins can build a sentry cannon, summon 10 American soldiers, or summon 50 mobilization troops. However, no matter what you do, there are pros and cons.

Building sentry guns can reduce casualties, but it also has great disadvantages. Being unable to move is the biggest problem. As long as the opponent is far away from the attack range of the sentry guns, then the sentry guns are just "decorations" and very expensive...

But if you summon American soldiers or mobilization troops... what if the other party has a sniper attack? Besides, there is no guarantee that the other party will fly over with a rocket to surprise you!

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

Summon American soldiers and conscripts!

Yes, what Han Feng lacks the most now is the personnel problem. Even though there are sentry guns guarding the entrance and exit of the building, it is only a one-sided defense and cannot provide all-round protection.

The back of the building is out of reach of the sentry guns. Once the enemy reacts, it will be too late for you to run away!

Of course, Han Feng also wanted to build sentry guns or machine gun bunkers behind the building for defense, but think about it carefully...

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

Second: Building a large number of defensive buildings may ensure temporary safety, but if you break through, it will be a bit stretched.

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

Fourth: The moment you break out of the encirclement is when you need personnel the most. Instead of holding on to the sentry cannon, you might as well fight!

As long as you kill Weige! You will be relatively safe.

"System, summon five American soldiers and twenty mobilization troops! Confirm, hurry up." While the sentry cannon was still intimidating and the other party had not yet reacted, Han Feng quickly ordered the system to summon red alert soldiers.

"The system is summoning, 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 slowly burning cigarette in my hand, I felt as nervous as a countdown...
Chapter completed!
