The first thing that came into view was a row of zombies, who walked out of the gate of the institute and down the steps to the commando team in front of the small train.

To prevent unnecessary damage, Senna said, "Tony, you go to the cab and be ready to get the train up at any moment!" ”

"Yes, ma'am!" Tony said as he went to the cab, opened the door, and stood there with an assault rifle.

"Don't shoot yet, wait until the zombies get closer!"

There were more and more zombies, pouring out from the inside, and Senna said again: "Attention, you must hit the head, so that you can kill with one shot, and aim for me!" ”

Senna fired the first shot, and then everyone began shooting at the zombie's head.

Seeing that there were more and more zombies, and it was too late to shoot, Senna said again: "Hit hard!" ”

Gatling began to spin and roared, and the platform erupted in gunfire, bullets pouring wildly and cartridge casings clattering to the ground.

Seeing a large number of zombies slamming to the ground, even this can't stop more loss frenzy from coming, and a new zombie variety has appeared in the zombie group:

Zombie Dogs!

There was no hair on his body, as if he had been skinned, bloody, but the speed was extremely fast, and he ran over at a high speed, and there were a large wave of zombie dog racks mixed with more zombies.

“What’s fuck！” Someone began to scold.

A zombie dog has already rushed to the front, was shot in the head, flesh and blood flying, seeing that there are more and more lost groups mixed with zombie dogs, as if the fight is incomplete, after a while, the platform has been a mountain of corpses.

But there are a large number of zombies pouring out like a tide in the back, and there are a large number of zombie dogs in the middle, and these zombie dogs are so fast that they almost bite the team members several times.

"Tony!" Xena shouted.

Tony, who was in the cab, immediately understood, put away his gun, started the engine, and prepared to go.

Seeing that the small train was about to move, they saw a zombie dog over the heads of many zombies, and hit the roof of the carriage with a bang, everyone was taken aback, followed by a series of zombie dogs flying over, crashing into the carriage, the tunnel wall, and the railroad tracks.

"Tony, what are you doing?" Senna almost yelled.

I never thought that there were so many zombies in this underground ant nest, I heard Speith say that there are more than 500 staff members in the underground research institute, but there are definitely more than 500 zombies in this underground research institute!

Tony shouted, "I can't get started, the zombies have destroyed the train's power system!" ”

“Shit！” Senna scolded and shouted again, "Hurry up, find a way to fix it!" ”

And at this time, a new zombie breed appeared in the field of vision: zombie monkeys!

Zombie monkeys and zombie dogs are also like skinned, covered in blood. But zombie monkeys are more agile than zombie dogs, they can jump and climb on pillars, chests, and guns are difficult to hit.

One of the team members finished firing the bullet and stepped back to change the magazine, and at this moment, a zombie monkey rushed over, pounced on the soldier, hugged it and bit it, and the soldier screamed and shook it vigorously.

Senna pulled out her dagger and slammed it into the back of the zombie monkey's head, and the zombie monkey screamed and ran out of breath.

Senna handed him a needle and said, "Get back into the carriage and inject yourself!" ”

After the soldier entered, Senna returned to the battle formation, and seeing several monkeys rushing over, she quickly shouted, "All back to the car, Tony, have you repaired it?" ”

The crowd shot and retreated to the car.

Two zombie monkeys ran over, grabbed one of the soldiers, one on each side, hugged his arms and bit him, the soldier screamed in pain, and before everyone could save him, another zombie dog pounced, stood up, and bit him on the neck.

Immediately, the soldier was lifeless and paralyzed.

More zombies poured in. The soldier was immediately submerged in the corpses, bitten by madness, and as soon as a few people got into the carriage, two more soldiers were dragged down by the zombie monkeys.

"Hurry up and close the door!" Senna said as she pulled the door with another soldier, and motioned for the Gatling to step back in.

But as soon as the soldier let go of Gatling, he was immediately dragged down by two zombie monkeys.

In the blink of an eye, Senna lost her four brothers, she was very sad, but there was no way, in order for the living to survive, she had to return to the carriage and close the door.

As soon as the car door was closed, I heard Tony's scream, and it turned out that several zombie monkeys had rushed into the cab.

Senna immediately rushed over to get Tony back.

But when she got to the cab, she saw that Tony was also being dragged down. Fighting back her grief, she pulled down the isolation door between the cab and the car, and another soldier rushed over to help her pull it down.

When the train came down, the cab was in front, so if you want to get back to the ground, the cab will be pushed forward in the back of the car.

The rear of the car is facing the direction of the tunnel to the ground, and a small window, which is dark, leads to the far ground direction of the tunnel.

The carriage faces the direction of the platform, there are two small windows, and you can see that the platform is crowded with zombies, zombie dogs, zombie monkeys, and stacked corpses on the platform.

"What should I do?" One soldier cried, "Let's not be trapped in this stuffy jar, we're going to die here!" ”

There were five other people in the carriage, captain Sena, engineer Space, and three other soldiers.

Sena was just about to reprimand him, the carriage jerked violently, and everyone was shocked and screamed, it turned out that the zombies on the platform were hitting the carriage together, and under the impact of many zombies, monkeys, and dogs, the iron shell of the carriage began to deform.

"Bang, bang, bang!" One after another, and so on.

The corpses were bound to eat them all alive.

Senna sat on the ground in despair, leaning against the carriage, and she didn't know what to do.

"We're going to die!" The soldier began to cry again.

"What are you crying about?" Another soldier scolded and was going to beat him.

Senna said, "Let him cry, no one will survive anyway." ”

As he spoke, he felt the rails begin to shake, and the rhythm of the impact outside slowed down.

"What's going on? Is there going to be an earthquake? Someone asked.

"Look over there!" A soldier pointed to the back of the car.

Seeing a very bright light shining through the small window at the back of the car, Senna walked over to look, and when she came to the small window, she saw a very bright light in front of her coming from the tunnel far away, and that direction was exactly the direction leading to the ground. Don't......

The sound of a train moving, and the sound of a horn.

Senna shouted backwards, "Stand back! ”

Then he also stepped back, and a small train came from the ground, and it looked like it was about to collide with this small train!
