There are three minutes left until the Sentry Cannon builds time!

"Hurry! Come on! Draining the bullets in the assault rifle, Han Feng muttered anxiously in the space of the magazine.

Due to nervousness, Han Feng's hand to change the magazine trembled slightly.

It was difficult to change the magazine, and just as Han Feng raised his gun and was about to shoot, there was a lot less firing around him.

Turning his head, he saw that three American GIs were retrieving their M9 pistols......

There are no bullets, even the pistol is out of ammunition. For a moment, Han Feng felt a hint of despair.

Relying on himself and Wayne alone, they will definitely not be able to stop the zombie frenzy in front of them! However, even if Han Feng's team was now fully equipped with bullets, it seemed that it would not be able to stop the attack of tens of thousands of zombies.

"Boom...... Boom! More than ten meters away, the fence of the school was squeezed by a large number of zombies, and there were several fractures.

The same collapse situation appeared at various fences, once a position was lost, the zombies would be like a collapsed dam, instantly drowning Han Feng and his party.

Not daring to stop, Han Feng kept firing bullets, and in a hurry, the 100% kill rate was decreasing. But at this time, he couldn't care about that much.

There are less than two minutes left before the Sentry Cannon is built......

"Summons four American GIs! Confirm! Come on! With the communication system in his mind, Han Feng summoned four American GIs.

Even if he was in a hurry, he wouldn't summon one more Red Alert soldier.

There is no other reason, and it can't be taken away...... There were a total of nine cars, eight of which were fully loaded, and only his own car could still seat four, so Han Feng only summoned four American soldiers.

"The system is calling, please wait." Hearing the sound of the system, Han Feng could only pray that the zombies would come out of the cage later......

"Dada! Click! "In a dozen seconds, the assault rifles ceased fire again. After hesitating for a moment, Han Feng replaced the last magazine.

At the moment, he only had one last magazine left, but Wayne was still firing, but presumably there were not many bullets.

"And the captain of the high-explosive grenade, prepare!" Looking at the fence that seemed to be shattering in the next second, Han Feng gave the order for a high-explosive grenade attack.

The three American GIs took out high-explosive grenades and held them in their hands, waiting for Han Feng's order.

"Throw it away!" Han Feng shouted, and the three American GIs threw high-explosive grenades into the school.

"Boom! Rumble!! Rumble! Three explosions followed, and the flames burst into the sky.

The three shockwaves entangle and reinforce each other, shattering everything in the attack's range!

When the huge shockwave sounded in the zombie horde, the zombies in the front row turned around again and headed towards the place where the sound sounded.

"Good!" With a whisper of congratulations, Han Feng opened his mouth and said, "Ceasefire." ”

The air was silent again...... Listening to the footsteps of the zombies, Han Feng knew that it wouldn't be long before the zombies would pour out again, and the next time they would ...... Maybe that's when the fence breaks!

One minute to go! One minute before the Sentinel Cannon will be built!

At this time, two newly summoned American GIs had already appeared beside Han Feng.

"Roar! Roar ......" inside the school, the zombies roared again. Under the crowding of zombies in the rear, the zombies in the front row poured in again.

“27…… 25…… 23…… 20…… Fire! Silently counting the countdown to the construction of the sentry gun, Han Feng looked at the distance of the zombie attack and ordered to fire.

"Da Da Da! Dada! "The newly summoned GI and Wayne simultaneously pull the trigger of their pistols and kill the zombies inside the walls.

"Boom! Tear and pull! "The fence of the school...... After all, under the squeeze of a large number of zombies, it broke through!

The sound of the fence tearing seemed to tear Han Feng's heart apart, and in the face of the unstoppable zombie frenzy, all that was waiting for him was to be drowned!

“3！ 2！ 1！ Sentinel Cannon, Construction !! "At the moment when the zombies rushed out of the fence, the countdown to the construction of the sentry cannon was just completed!

"Boom! Hoo ......" like a wall, a dull sound of smashing the ground sounded, followed by a gust of wind blowing.

After the order to build was given, in the position that Han Feng had expected, a fort stood there.

The pitch-black base and cannon body resemble a stealthy ninja in the darkness of night.

The one-meter-tall sentry cannon has two muzzles, and the black hole is pointed forward. At the top is an infrared scanner, with several red laser lines sweeping and exploring in front of you.

"The Sentinel Cannon has been built."

"The Sentinel Cannon is drawing power from the temporary base, please wait. The power is drawn. ”

"The automatic recognition of the sentry cannon is on, please wait. Automatic recognition is turned on. ”

"Sentinel Cannon ......"

A series of voices from the system sounded in his mind, and Han Feng, who was listening, was excited.

"Bang bang bang!" In an instant, the Sentinel Cannon automatically fired!

The two 70mm barrels alternately retract back and forth, firing one miniature shell after another!

Carrying clumps of flames, the miniature cannonballs glowed red. In the dark night, he drew a red line, as if cutting through the space, rushing towards the zombie group.

"Poof!" Each shell pierces the heads of several zombies, and then explodes inside the body of the last zombie.

Looking at such fierce firepower, Han Feng forgot his nervous mood just now for a while.

"Forehead ......" looked at the sentry cannon that was firing, and Han Feng stopped talking.

Pulling his gaze back into the zombie tide, Han Feng secretly sighed that it was not good!

A large number of zombies have broken through the fence, and in the distance, a large zombie horde is coming!

Just a sentry cannon at the moment would definitely not be able to stop such a huge number of zombies.

"System! Build machine gun bunkers! After thinking about it, Han Feng communicated the system in his mind and asked for the construction of a machine gun bunker.

"It takes ...... to build a machine gun bunker"

"Confirm! Fast! Han Feng's eager voice interrupted the system's words.

"Machine gun bunkers are being built, please wait."

After listening to the system's answer, Han Feng looked at the corpse tide again.

"Withdraw!" With an order, Han Feng led a large army to the location of the vehicle.

The sentry cannon is left here, continue to kill zombies, anyway, it is automatic shooting and automatic aiming, Han Feng doesn't have to worry too much.

The school is less than a kilometer away from the villa, and such a distance will take a certain amount of time for zombies with limited mobility.

The construction of machine gun bunkers is completely precautionary, if the sentry cannon can't withstand such a large number of zombies, he will not be overwhelmed by the zombies who break through. Making a machine gun bunker in advance can be in a critical situation, you don't have to wait for the construction time of the machine gun bunker, you don't want to take this risk, go home directly, Han Feng doesn't believe that so many zombies in the school can all come to the villa.

After getting into the car, Han Feng made sure that no one was left behind.

"Go home!" After giving the command in his mind, Han Feng quickly moved towards the villa with one foot on the accelerator.

After the vehicle traveled a few hundred meters, in front of a residential building closest to the school, Han Feng stopped the car and instructed a mobilizer to get out of the car, according to the instructions in Han Feng's mind, the mobilizer broke the glass on the first floor that best visualized the current situation of the zombies in the school, and let it lurk inside. The purpose is to "plug in the eye", because Han Feng's radar has a field of vision link function, he can link this mobilized soldier at any time to observe the changes in the corpse tide in the school.

After inserting the eyeliner, Han Feng, who was a little more stable in his heart, drove to the villa again.

A few minutes later, the convoy arrived at the entrance of the villa area.

"Everybody's on standby." After informing the driver of the vehicle behind him in his mind, Han Feng lit a cigarette and quietly waited for the passage of time.

"Build machine-gun bunkers." Stopping and waiting is all about building machine-gun bunkers just in case.

"Boom! "Calling ......" is the same as the appearance and sound of the sentry cannon. A large snow-white, circular defensive structure appeared at the entrance of the complex. The middle above the machine-gun bunker reveals an entrance and exit for one person.

Looking at the machine gun bunker that suddenly appeared, Han Feng was startled. After a pause, Han Feng contacted a mobilized soldier in his mind and asked him to get out of the car and enter the machine gun bunker to guard the gate of the community.

After watching the mobilized soldiers enter the machine-gun bunker, Han Feng was relieved.

"It should be okay this time......" Han Feng, who was still worried in his heart, muttered to himself like a child in trouble.

A minute later, Han Feng returned to the villa.

"Brother Han, I heard an explosion, are you okay?" Han Feng, who had just gotten out of the car, was intercepted by Wei Yun who ushered in him and asked.

"It's okay, there are too many zombies in the University of Science and Technology, and I almost can't come back there~" In a pretended relaxed tone, Wei Yun couldn't hear how eager the scene was at that time.

"Whew...... It's okay, it's okay. Patting his chest, Wei Yun put down the stone in his heart.

"You kid dare to poke the hornet's nest in college?! You don't know there are 30,000 monsters there?! On the side, Liu Rui, who heard Han Feng's actions, was amazed for a while.

"Now that the zombies in the university are basically all out of the cage, let's avoid the limelight tonight, and no one will go out if it's okay." After a pause, Han Feng continued: "I'll rest first, and I'll see you tomorrow." ”

Han Feng, who was focused on the battle situation, didn't care about talking too much to the two. Hurriedly walked to the second floor, and when he returned to the bedroom, he immediately contacted Radar.

"Vision link, view the school zombie dynamics." After speaking, Han Feng closed his eyes.

After opening his eyes again, Han Feng's vision was linked to the mobilizer closest to the school.

Seeing that the sentry cannon was still firing in the distance, the sound of firing attracted most of the zombies. Although there were zombies on the street in front of him, there were not many of them, and they just wandered aimlessly.

Seeing that there was no big problem, Han Feng was relieved.

Exiting the vision link, the gaze returns to the bedroom. After thinking about it, Han Feng's attention was on the system in his mind.

！！！

As soon as he entered the system, Han Feng was stunned, the gold coins were still increasing?!

"System, what's going on? Why is the gold still increasing?! With surprise, Han Feng asked the system.

"Report to the Commander, the Sentinel Cannon is killing zombies. With the commander as the center, the radar detection range within a radius of five kilometers is the effective area of killing. ”

The system's answer made Han Feng's eyes light up, in this way, he could send multiple teams to different locations at the same time to kill zombies together. As long as the range does not exceed five kilometers, you will receive gold coins.

"Great!" After a word of excitement, Han Feng began to plan.

At the moment, there are still 3,816 gold coins, and they are increasing rapidly. Frowning and thinking about it, Han Feng figured it out.

A sentry cannon costs 5,000 gold, a machine gun bunker costs 2,500 gold, and four American GIs 2,000 gold, which alone costs 9,500 gold......

It's really a lot of money. "...... I wanted to earn some gold, but I didn't expect to get into it so much! Muttering to himself in annoyance, Han Feng lay down.
