Alice and her party walked carefully on the ventilation duct, and after walking a distance, a bad news appeared in front of everyone's eyes, so that everyone had to stop.

The ventilation duct reached out into the ceiling at a bend, and the group's journey ended. Below everyone, there were more than 300 zombies gathered in one place, except for the four lickers who gave Zhu Kun a name as coolies, the other five lickers also watched Alice and her party with fierce eyes.

There are many zombies underground, including not only zombie researchers with protective shields, but also lickers with incredible speeds. And everyone's ammunition is almost exhausted, and there are only eight grenades combined.

"The front is the core lab, and the Frost King's control room is at the back of the lab." The doctor's hand grasped the pipe, and he pointed to a metal code door five meters away from the end of the pipe.

"Captain, zombies at a distance of five meters will never give us time to rush over, let's use grenades!" Matt looked at the group of corpses below, and then said in a deep voice.

"Our grenades are specially designed to deal with large-scale zombies, and the killing range is about eighteen meters. At such a distance, we can't run a single one of them in this sealed passage! Matthew pointed to his side, because the space here was only about twenty or thirty meters, and once it exploded, it would all be within the attack range of the grenade, which was why Matthew had never used a grenade.

"If you don't move, you will only be trapped here by zombies, you use guns and grenades to clean up the zombies, and I will decipher the code in the laboratory!" Peyton said as he pulled out his computer and pointed to the PINpad on the metal door.

"Clean up the corpses and buy time for Peyton!" Matthew is not a grinder either, and a little thought about it knows that this is the only way.

"Boom..... .....The grenade was loaded on the muzzle of the gun, and Matthew and Matt raised the muzzle of the gun and hit it twice at the densest place of the corpse.

The explosion rang out violently, and although the grenade was heavy on killing and no longer in range, such a close attack distance still made everyone feel that the heat wave was coming.

The explosion of the gun grenade cleared a large open space, and more than thirty zombies crowded together were blurred by the blood, and the strong smell of blood came to the nostrils.

"Fortunately, there is only one type of zombie here, otherwise there will be a few more zombies with ranged skills, and we will be all finished!" Matt said as he smiled as he reloaded the grenade again.

.....Before the two of them could open fire, the ventilation duct where everyone was standing shook violently and made a squeaky sound.

Matthew and the others' bodies shook violently with the shaking of the ventilation duct, and they all fell on top of the pipe, and even Peyton had to give up the plan to rush down.

"Help me, help me up!" Suddenly there was a shout in everyone's ears, and the doctor could not stand still in the shaking, and his hands were clutched on the chains of the pipe, but his body was exposed.

"Roar..... "The licker hiding in the corpse group roared, and a licker rushed out of the corpse and quickly headed for the doctor. And with a licker? The eater rushed out, and the others also watched eagerly.

"Shoot, shoot!" Matthew knew that he couldn't care about the doctor at this time, because if everyone went to pull the doctor, then once the licker rushed up, none of them would want to live.

"Da ....." the four of them, including Alice, opened fire, and the large net of bullets headed towards the rushing licker. Puff..... "The bullets kept hitting the licker's body, bringing up pieces of flesh and blood, but the licker still moved forward bravely, sweeping his tongue towards the doctor in one mouth.

'Help me, save me!' The licker's tongue wraps around the doctor's legs, jerking him out of the pipe.

The doctor exclaimed, clutching his head in his hands. As the body fell to the ground, the pistol also fell to the side.

The licker's movements were flickered, and his body jumped and pounced on the doctor's body, followed by the clattering and tearing sound and the flying of flesh.

"Da-da....." The licker feasted on the flesh, and as he stopped, several bullets swept across his head and exploded in the head.

As the saying goes, people die for money, birds die for food, and the licker moves at an astonishing speed, and everyone never reaches his orange-sized head. But this stop, it will kill him.

"Doctor, doctor!" Alice and the others looked down while guarding the other lickers, only to see that the doctor's eyes were wide at this time, and half of his head was bitten off by the lickers.

"Boom!" The rest of the zombies swarmed up with the smell of blood, all huddled on the doctor's body, constantly gnawing on his flesh.

"Die, bastards!" Matthew was furious with another attrition, and with a slight lift in his hand, a grenade tail smoke headed towards the zombie lying on the doctor's body.

"Boom!" The explosion rang out in everyone's ears, and because the doctor's position was under the ventilation duct, the pipe shook violently again as the grenade sounded.

"Ding..... Click......"

One of the chains of the pipe broke in response, and the entire ventilation pipe sank downward, so that everyone had to hurry to grab the iron chain around them to make sure that they were not thrown off by the shaking pipe.

"Roar!" Taking advantage of the moment when everyone found their balance, the two lickers rushed forward and pounced on everyone.

"Boom!" At the critical moment, the gun in Matt's hand also went off, and the grenade flew towards the pounced licker with a tail of smoke, colliding with the two lickers.

"Click..... Boom...... "Although Matt's reaction was correct, when the blast came again, the ventilation duct that pinned everyone's hopes could no longer hold on.

The chains on the ventilation pipes broke one by one, and Alice and her party fell down with the pipes and slammed them to the ground.

Seeing that the flesh and blood they liked was right in front of them, the zombies' footsteps actually sped up and rushed towards Matthew and the others.

"Back off, everyone back off!" Matthew, who was closest to the corpses, roared again and again, and the grenades in his hand rang out one after another, and in a short period of time, the four grenades that Payton had given him were fired into the corpses.

After being attacked by Matthew's fierce blow, the zombies attacked slightly, and at this time, the others got up from the ground again and discovered Matthew's situation.

At this time, Matthew was sitting on the ground, the rifle in his hand kept ringing, and he didn't make any movement to get up.
