Just as everyone was about to rest in place, the sound of metal scraping against the ground came to their ears.

It turned out that there were more and more zombies at the entrance of the mall, and the zombies in front were moved forward by the zombies in the back, and most of the zombies in front had been squeezed into human shape by the shelves, and some were even squeezed so that the internal organs burst out of the wounds, which was very disgusting.

As there were more and more zombies behind, the squeezing force made the shelves blocking the door of the mall keep moving backwards, and the shelves rubbed against the ground, making a creaking sound, obviously the temporary obstacles could not stop the zombies for long.

"Quick! You can't stay here for long. Hurry up to the top floor and move at speed. The major stood up from the ground with his hands propped up and yelled at the resting soldiers.

Seeing the scene in front of them, everyone understood that the obstacles blocked at the door could not stop the zombies for long, so they got up from the ground and ran towards the staircase on the side.

Just as everyone ran to the staircase, there was a sound of heavy objects collapsing behind them. I was shocked. I didn't expect the shelves to block only such a little time.

Listening to the roar of the zombies behind them, everyone ran to the top floor with all their might, and finally saw the door to the rooftop in the first, second, and third floors, but now the gate was locked.

The major hit it twice and didn't open it, so he immediately pulled out the pistol on his waist, fired several shots at the door lock, and directly smashed the door lock to pieces, kicking open the iron door.

"Hurry up and get out!" The colonel commanded the people to go out, and he stood at the door.

Wait until the last soldier runs over, looks at the grenade on his body and says, "Quick! Give me the grenade! ”

The soldier did not hesitate, took off all the grenades on his body and handed them over, and when he took the grenades, he saw the major pull the ring of the grenades and threw several grenades to the staircase.

"Lie down!"

The major dodged into the rooftop and shouted a reminder to everyone, and then one of them fell to the ground, and the other soldiers heard his reminder and reflexively lay on the ground.

"Boom!"

A violent explosion came from the staircase, and in the narrow staircase, the power of the grenade was fully exerted. The staircase that originally led to the rooftop was directly blown down by these grenades.

The falling stone smashed directly into the climbing zombies, and suddenly a large group of zombies were smashed to the ground. The zombies in the back stepped on the body of the zombie in front of them regardless of it, and rushed towards this side frantically, but the stairs leading to the rooftop had been blown off by a grenade, and the zombies in front of them hit the wall one after another.

But soon, the zombies in the back pounced on them, and directly stepped on the bodies of the zombies in front of them and continued to climb up, these zombies were like stacking Arhats, stacking them layer by layer. It won't be long before a human ladder is built!

The major got up, spat out a mouthful of blood, shook his head, walked to the door to check, and saw the scene.

"Quick! Shoot at the zombies above, can't let them climb up, hurry! The Major roared behind him.

But the staircase was so big that it couldn't accommodate more than 30 soldiers to open fire. In desperation, the major could only divide the remaining thirty or so soldiers into six teams. Five people per group. Take turns firing at the staircase.

As the soldiers fired, zombies continued to roll down from the pile of corpses. Even so, the zombie height is still rising.

"Signal Corps, Signal Corps. Fast! Contact the base and request support! The Major shouted to the communications soldier beside him.

"Yes!" The communications soldier hurriedly replied.

Just in case, he had a radio station on him at all times, otherwise the group of them would have been trapped here. He put down the radio station on his body, quickly adjusted it, and began to call the base.

Seeing this, the major turned around and joined the soldiers in strafing the zombies below the staircase.

Seeing that the height of the zombies was getting higher and higher, the major team asked, "Are there any grenades?" Who still has grenades? ”

"I still have two!" A soldier shouted with a grenade raised.

"Is there anyone else?" No one answered, and the Major's heart was cold. There are only two grenades left, and it is estimated that it will be difficult to eliminate the pile of corpses below.

"Major. I still have two pieces of TNT on my side! A soldier cautiously held up two yellow solids in his hand, which were originally used to blow up the town's vault. But before he could blow up, he was surrounded by zombies.

The major was overjoyed, "Quick, throw the explosives down." ”

"No, Major. These two pieces of TNT are very large, and if they were put down, I guess this balcony would be blown up directly. The soldier replied nervously.

Hearing this, the major's head is bigger, if this blows up the entire balcony, then they will become a delicacy for zombies.

"Throw the grenade down first. Hurry up and disassemble the explosives, as long as they don't blow up the rooftop. Hurry up! The major urged.

Hearing the Major's instructions, the soldier with the TNT immediately placed the explosives on the ground and carefully began to disassemble them, while the other soldier gave his only two grenades. I pulled out the tab and threw it down.

"Watch out for grenades!" Shouted, and quickly fell to the ground.

Hearing his words, the others stopped shooting and quickly lay on the ground, while the soldier who was dismantling the TNT let out a foul breath and protected the TNT under him, if this was detonated, everyone would be doomed.

"Boom~~Boom~~" Two explosions came from the staircase, followed by the impact of the grenade, flying up with all kinds of minced flesh and falling on everyone like rain.

There was a foul smell in the air, and many people couldn't help but spit it out when they smelled it.

The Major got up from the ground, knocked a piece of meat off his shoulder with his hand, held back his nausea, and looked towards the staircase. I just glanced at the situation in the corridor, and immediately ran to the side and vomited.

At this time, the scene inside the staircase, like meat in a meat grinder, was full of stumps and broken arms, mixed with many intestines and some messy internal organs, which covered the white wall of the staircase.

And with this round of explosions, the pile of corpses built by the zombies was blown up, which bought everyone a lot of time.

The soldiers got up from the ground one after another and quickly cleaned up the minced meat from their bodies, no one knew if there was a virus in the meat, and it would be troublesome if they accidentally fell into their mouths.

Just when the major was about to vomit out his bile, the communications soldier on the side ran to him to report to him.

"Report! Major! The base has sent a helicopter to the rescue, and the base has told us to hold out for ten minutes, and after ten minutes, the helicopter will arrive on our side. ”

Hearing that the base had dispatched a rescue, the major's face was overjoyed. Hurriedly told the news to everyone? Hearing that the base had sent a helicopter to the rescue, everyone's spirits were lifted. Without waiting for the major's command, they ran to the staircase. Holding back the discomfort in his heart, he shot desperately at the zombies below.
