Inside, there was a hallway, and there was silence in the hallway, except for the mottled walls that remembered the stories that had happened here in the past.

The dust was everywhere, but mostly settled, and it was only when the two of them walked gently that they lifted gently at their feet.

At the other end of the hallway there is a hall filled with cabinets containing machines. Some cables protruded from the cabinet, tangled haphazardly on the floor.

In addition to the wire, there is a lot of debris on the ground.

Chen Jianing looked at the machines and shook her head from time to time. She didn't go too far from Ding Xiu's side, and only stopped when she saw something she was interested in.

"Are you looking for something?" Ding Xiu was a little curious.

"I'm looking to see if I can use the right little parts." Chen Jianing took her eyes back from the dusty equipment, and said disappointedly: "It's a pity that they are all too old, and the interfaces and models are outdated." ”

"What do you want parts for?" Ding Xiu brought Chen Jianing to this institute to escape the dangers of the desert at night, and he didn't understand why the girl came here after she came here, but he was so interested in these machines and equipment.

"If there's a good part, I can help you upgrade your biometrics. Well...... For example, the map feature can help you keep track of the local environment and your route when you go anywhere. Chen Jianing thought for a while and said: "In addition to the map function, the communication function can also be integrated. ”

"What parts do I need?" Hearing that the biometric identifier could be upgraded, Ding Xiu was immediately interested.

"The parts in these devices are not good, and the stability is too poor." Chen Jianing said with regret.

"We'll talk about that later." Knowing that it was not easy to upgrade the equipment, Ding Xiu dispelled his thoughts, and the most critical issue at the moment was how to survive.

The two walked through the hall, and the further they went, the more obvious the traces of the people who had lived here.

Clothes, bedding, books...... There were all over the place, and the dust covered them with a layer of vicissitudes.

An iron door appeared in front of him, and Ding Xiu gently pushed it open, finding that the musty smell inside was much stronger than that outside. He slowed his pace and stared warily around him.

Chen Jianing wore the mask that Ding Xiu gave her, and she didn't notice the changes in the air inside, she tore a yellowed photo from the cabinet next to the wall, and saw that it was a little girl holding a Mickey Mouse toy.

"Where have you been?" She murmured to the picture, her expression a little heavy.

"Be careful, something isn't right." Ding Xiu whispered, he heard some movement nearby, and these sounds came from different directions.

With a "bang", something hit the nearby iron gate, and then there were suddenly countless messy footsteps nearby.

A hideous-looking figure rushed into view, and under the light, Ding Xiu and Chen Jianing saw that its face could no longer see its original facial features because of heavy decay.

"Zombies, F-class mutant creatures, bodily fluids or wounds caused by attacks are contagious, and they like to eat the flesh and blood of living people." The biometric identifier reported the information recorded.

"Their weakness is the head." Chen Jianing added an important piece of information.

Ding Xiu didn't wait for the zombie in front of him to approach, and had already shot through its head in advance according to Chen Jianing's prompt.

The zombie staggered a few steps, and its body continued to pounce on Ding Xiu.

"Not dead?!" Ding Xiu was stunned for a moment, but fortunately he reacted in time, and his other hand had already been raised, and he used the portable lamp to smash the loss to the ground.

The zombies struggled to get up, but their hands and feet were noticeably less agile than they had been.

"Ho~ho~" A low roar sounded all around, and the messy footsteps had come closer.

Behind the oil drum, next to the machine...... More than a dozen zombies crawled out of the surroundings in an instant. They were ragged and smelled of a disgusting stench, and their gray eyes swooped at the two men in the room.

"No, these aren't ordinary zombies." Chen Jianing shouted.

"Let's go!" Ding Xiu realized that the situation was wrong, and pulled Chen Jianing to flee in the direction where he had not yet been surrounded.

In order to cover Chen Jianing during the escape, Ding Xiu also turned around and fired two shots, putting down the zombies chasing in front.

When the zombie fell to the ground, the body tripped several companions who were chasing after it to the ground, slowing them down a little.

There was only a small door in front of them, and the two of them pushed the door in, wondering if there was still danger behind the door.

The zombies behind him were in hot pursuit, and at the moment when Ding Xiu and Chen Jianing rushed into the door and just closed the door, the bodies of several zombies slammed into the door.

The "thump" thump rang at the door, sending dust down in a puff.

"This door is not strong!" Ding Xiu locked the door, but the impact from the door made him a little uneasy. He saw a large iron cabinet next to him, so he quickly rushed over and pushed the iron cabinet over.

"Ah!!h The iron cabinet was very heavy, and Ding Xiu roared and used all his strength to eat.

Chen Jianing also went up to help, and the two finally rushed to the door before the zombies broke in, blocking the door with an iron cabinet.

With the double barrier of the door lock and the iron cabinet, the zombies outside the door can't enter, but that side is also the direction of Ding Xiu when they came in, that is to say, the retreat has now been blocked.

The footsteps came again, and Ding Xiu followed the prestige and found that zombies also appeared in the corridor behind him.

Cold sweat broke out on his forehead, and he was a little hesitant to raise his gun to fight.

"Run." After a short period of weighing, Ding Xiu still decided to take Chen Jianing and continue to escape.

Bullets are limited, and in such an unfamiliar environment underground, Ding Xiu is not even sure that he will escape with his whole body, let alone a Chen Jianing. He is not afraid of death, but he has a different idea of Chen Jianing.

As the so-called good people do it to the end, send the Buddha to the west. Since he saved this girl from the man in black, Ding Xiu will definitely do his best to take care of her.

There was also a side door nearby, which was the only way out, and Ding Xiu had no choice. But it's better not to have a choice, sometimes you waste precious time by making a choice.

The messy debris on the ground helped Ding Xiu, and the zombies chased quickly, but their ability to avoid obstacles was obviously not as nimble as humans.

Chen Jianing's hand was held by Ding Xiu, and although there were many zombies chasing after her, she had an inexplicable sense of security in her heart.

This is the first time that a girl has never been held by someone of the opposite sex of the same age when she has grown so big. Coupled with such a thrilling experience, Ding Xiu's name has left a heavy mark in her heart.

Empty rooms, hallways, stairs...... The two of them ran when they saw the road, as long as there were no zombies, it was the direction.

The movement in the escape alarmed more dangers, Ding Xiu didn't expect this to be the case in the laboratory before he came in, unlike the silence at the entrance, the depths of the research room were like a pot of boiling water at the moment.

Suddenly another zombie appeared in front of him, and there was no way to escape from the side, Ding Xiu's speed did not slow, and he rushed straight over and kicked it to the ground.

The sound of the gun rang out, and after a shot, the zombie that was trampled under Ding Xiu's feet finally stopped moving, its head was smashed by the bullet, and almost all of it above the neck became small pieces of minced meat.

"Is that dead?" Ding Xiu didn't have time to think about it, because the footsteps behind him chased them all the way like maggots on tarsal bones, and they couldn't shake them off.

The research institute was full of zombies, and the road ahead was getting narrower and narrower, and Ding Xiu no longer thought about the number of bullets left, because several times if he didn't shoot in time, he would have died.

Chen Jianing's physical exertion was very great, she gasped, and her steps slowed down.

"Hold on a little longer." Ding Xiu gave her a boost.

The girl gritted her teeth and kept up with him again.

Just as Ding Xiu and Chen Jianing were climbing a staircase, a straight corridor appeared in front of them. The corridor was very long, and because of the light, Ding Xiu couldn't see the end of it.

He stopped, his face a little hesitant.

Chen Jianing knew what Ding Xiu was hesitating about, if there were zombies at the end of the corridor, there would be a dead end ahead.

The black crushing corpses had chased downstairs, and Ding Xiu could even hear their footsteps on the stairs. He kicked at a locked iron door next to him, but it didn't move.

There was no way, Ding Xiu was ruthless and pulled Chen Jianing into the long corridor.

"The exit is just ahead." Seeing the sign on the wall of the corridor, Ding Xiu's spirit was shocked, and his body seemed to have regained a lot of strength.

Chen Jianing was also encouraged, and she followed Ding Xiu all the way forward, running towards the end of the corridor.

The two ran desperately, and Ding Xiu, who was running in front, was coldly slammed against the wall by a figure rushing out of a room next to the corridor. The sudden accident caught Ding Xiu a little off guard, so he instinctively held the gun in front of him.

The zombie's hands stretched out towards Ding Xiu's shoulders were held by the gun, and it grabbed the body of the gun, and the strength of its whole body pressed on Ding Xiu's body.

Its face leaned towards Ding Xiu's neck, only because the gun mount blocked its body in the middle, preventing it from going any further.

The zombie wanted to bite Ding Xiu but couldn't, and kept roaring in his eagerness, Ding Xiu wanted to push it away, but he was afraid that the zombie would turn around and pounce on Chen Jianing.

He had to let the zombie's attention continue to stay on him, and the situation suddenly became deadlocked.

Chen Jianing was stunned by the scene in front of her, and when she saw the zombie pounce on Ding Xiu, she didn't know where the courage came from, and she raised the flashlight in her hand and smashed it at the zombie's head.

Chen Jianing's attack caused almost zero damage to the zombies, but this action made the zombies a little distracted.

The zombie noticed the girl next to him, but he was reluctant to let go of Ding Xiu in front of him.

While it shook its head left and right, Ding Xiu finally seized an opportunity.

The arm against the gun instantly exerted force, pushing the zombie in front of him out. The zombie's grip on the gun still didn't let go, but Ding Xiu didn't let go of his hand, because he didn't have time to continue pestering here.

The gun had to be left unwanted.

The zombie fell into the room he had just pounced out of, Ding Xiu pulled Chen Jianing and continued to run forward, and the corpses behind him had already poured into the corridor.

If it weren't for the zombies that suddenly pounced just now, the narrow corridor might have helped Ding Xiu delay more time, and the corpses had significantly slowed down after entering the corridor.

But they were slow, but Ding Xiu didn't dare to be slow, and every minute and second of running was a race against death.

"Door!" There was still a door at the end of the corridor, Chen Jianing shouted silently, his eyes full of despair.

The two ran to the door, Ding Xiu suddenly let go of Chen Jianing's hand, and his body slammed into the door.

He didn't know if the door was open or locked, but the corpses behind him had poured into the hallway, and the zombies that had been pushed into the room just now had run out again.

As long as this door can't be opened in a few seconds, the fate of him and Chen Jianing will come to an end here.

In this collision, Ding Xiu gambled his life.
