Sunlight shines through the ocean-blue glass windows into the building, reflecting a faint blue light in the corridors, and the T-virus-infected crows hover in the sky, croaking and croaking, looking for anything to satisfy themselves.

The city was dead silent, and the zombies had fallen into a deep sleep many years ago when humanity was almost extinct, waiting for the day when an unlucky human would break into their forbidden zone.

Zhang Heng's eyes were full of exhaustion, it had been eight hours, and it had lasted for eight hours, and his actions of being careful not to make any sound had made his whole body and mind exhausted.

At this time, he had climbed to the thirtieth floor, less than half of the distance from the data room on the fifty-third floor, and behind him were zombies who had been killed by a knife and died in their sleep.

He didn't know how many zombies he had killed along the way, and at first he was counting them one by one, but as the number of zombies he killed exceeded hundreds, he finally couldn't continue counting.

This is still the result of only clearing the zombies in the corridor, and if the office on each floor is also cleared, it is estimated that it will not be cleared in a week.

"That's it for today."

Zhang Heng shook his dizzy head, smeared some zombie black blood on his body again, and then walked towards the bottom of the building step by step with the stench all over his body.

So far, there have been no lickers, and perhaps the big ones have long since left, after all, their mobility is far greater than that of zombies, and they can hunt everywhere, so there is no need to be trapped in the building.

All the way back to the security room, Zhang Heng climbed into the iron cabinet again, and then took out the instant noodles and mineral water that he had been reluctant to eat and devoured to eat and drink. The bread was eaten dry, with mineral water, but after a while, a piece of bread was swallowed into the stomach.

Looking at the half-left mineral water bottle and the empty instant noodle box, Zhang Heng secretly swore that he must bring enough food next time he went on a mission, and then closed his eyes tiredly.

1. No dreams at night.

The next day, Zhang Heng woke up at eight o'clock in the morning, strictly speaking, he was woken up by hunger, his stomach kept growling, and he had no choice but to light a cigarette......

When the cigarette was finished, Zhang Heng vigorously extinguished the cigarette butt, and then began to clean the Ambrera building again.

Fortunately, the further upstairs he went, the more sparse the density of zombies became, but in the afternoon, Zhang Heng stepped on the data room on the fifty-third floor.

As a huge business empire, Zhang Heng had a hunch that Ambrera's data room would not be too small, but he didn't expect that the data room would occupy an entire floor of space, and on the door of the fifty-third floor was a triple combination lock composed of numbers, fingerprints and iris. And the top of the gate is written in English: The company is heavy, and idlers are not allowed to enter.

"Holy! How can this be? ”

Zhang Heng was dumbfounded, he did a lot of calculations, but he didn't calculate that the data room was still locked, and from the metal door like a bank safe, he knew that this door could never be opened by violent means.

"Julian, get me out!" Zhang Heng was anxious and immediately contacted the auxiliary system of the dimensional star.

"Eh, that's rude, Julian is still taking a nap!" Suddenly, a two-dimensional Lori wearing a printed nightgown and rubbing her sleepy eyes appeared on Zhang Heng's retina.

"Sleep your sister, can you explain to Lao Tzu what the situation is?" Zhang Heng said angrily, if the door can't be opened, then how can he go to the data room to get the information on the T-virus?

Yu Li'an glanced at Zhang Heng with an idiot's eyes, and then said slowly, "Did Yu Li'an say that the mission target is in the data room?" ”

“…… Nima! When Zhang Heng heard this, he almost fainted, could it be that he had spent nearly two days of hard work, and all of them had done useless work?

Calm down, calm down!

Zhang Heng took a deep breath, suppressed his mood on the verge of collapse, and then thought about it carefully, it was not useless, if you want a sample of the T virus, then you can only get it from the laboratory on the fifty-fourth floor, so you still need to clean the zombies in the entire building, and after thinking of this, Zhang Heng immediately felt comforted in his heart. But...... If the data room can't be opened, where else can I get the T-virus data?

That's right!

Suddenly, Zhang Heng thought of something, if the virus broke out suddenly in this city, then what was the first thing those researchers had to do?

It is impossible to flee immediately, because as a high-level Ambrera, what is the difference between abandoning a company and a general abandoning a position, and it is inevitable that he will be angry with his immediate boss at that time. Therefore, at the moment of crisis, the first thought of those people is definitely to flee here with the most valuable information!

Therefore, it is likely that the materials are not in the data room!

Thinking of this, Zhang Heng already had a plan, he directly set his eyes on the ceiling and walked straight towards the fifty-fourth floor.

The higher the floor, the smaller the number of zombies, after all, after the outbreak of the crisis, the first thought of ordinary people is to go downstairs and escape, so the density of zombies is sparse the higher they go, and the fact is that Zhang Heng did not encounter a zombie at all in the last few floors.

And he walked from the fifty-third floor to the fifty-fourth floor, and it stands to reason that it was absolutely clean.

But when Zhang Heng walked to the corner, he was shocked, only to see that in the center of the stairs, a pool of broken corpses with unclear shapes appeared in front of him.

This clump of broken corpses has long since dried up, the minced meat and bone stubble are mixed together, and after more than ten years of air drying, it has completely turned into a black-brown bacon cake, but when he saw this crushed corpse, Zhang Heng had a deep palpitation.

Ordinary zombies can eat people into skeletons at most, and they can never have the power to pinch people into meat sauce, even a group of zombies can't do it!

So, what is the culprit of all this, the answer is self-evident!

Taking a deep breath, Zhang Heng slowed down again and walked towards the top with a cautious mentality.

The staircase was a cloister structure, and as soon as he walked halfway through, he could see the outline of the upper level at the turn, and his tense heart was slightly relieved when he saw the open door of the laboratory.

Fortunately, the laboratory on the fifty-fourth floor was not locked, otherwise he really wouldn't know how to complete the task.

However, when Zhang Heng walked up two or three steps again, his breath was stagnant, and a figure like a nightmare was lying not far from the door of the laboratory, blocking his way!

Through the half-hidden door, Zhang Heng saw that this figure was about three meters long, with sharp claws extending out of its forelimbs more than a foot long, and its whole body was red! It's like a skinned beast, with no skin at all!

Only the well-developed muscles are exposed to the air, rising and falling with the breath!

And the head of the creature, there are no organs such as eyes and nose at all, only a huge mouth across the face, and the hideous appearance is like a monster that can only appear in nightmares!

Lickers!

Zhang Heng's heartbeat accelerated irrepressibly, and sure enough, there was a monster hidden in this building that he didn't want to see!

If a zombie is a beast with only instincts, then the licker is the king of beasts! Although the predecessors of licking eaters and zombies are both humans, their strengths are very different - zombies are defective products born after humans are infected by viruses and the body dies, while lickers are biological weapons that humans directly inject T virus stock solution when they are alive and then put them into the incubator to cultivate!

Compared with those zombies that look disgusting and actually have no combat effectiveness, the danger of lickers is undoubtedly dozens or hundreds of times that of zombies!

At this time, the licker was holding his head and lying on his stomach in front of the messy laboratory door to sleep, because it could not find humans to serve as food, it could only choose to sleep like many zombies to reduce energy consumption. Behind it, however, is an incubator-like apparatus and a completely destroyed window.

The box-like instrument should be the delivery room where it was nurtured, and the hole was the entrance and exit for it to go out to find food.

Damn Ambrera Corporation, who dared to breed lickers in the downtown area, no wonder the entire human world was destroyed.

Zhang Heng stood in front of the door of the laboratory in fright, looking at the licker more than ten meters away, and didn't know what to do for a while. He looked at the dagger in his hand, and then at the monster that only appeared in nightmares, and even he himself didn't believe that he could kill the other party with this broken dagger for dozens of dollars.

As soon as he thought of this, Zhang Heng's eyes lit up suddenly. That's right, although it's impossible to kill the licker, but there's no need to fight with the other party, just lure the other party away, right?

Thinking of this, Zhang Heng suddenly had a plan, he slowly withdrew from the fifty-fourth floor and returned to the fifty-second floor. This time, he did not stay in the hall on the fifty-second floor, but chose an office at random and walked in carefully.

The office was a mess, with a lot of materials piling up on the desks, but there were no zombies. He looked at the settings on his desk, and four desktop computers were sitting upright on the desk.

That's you!

Zhang Heng narrowed his eyes, thought about the plan in his heart, and then resolutely opened the window and threw the four computers out as fast as he could!

Bang! Bang! Bang! Bang!

Four shattering sounds, which were not too loud but not too low, rang out one after another, transmitting a long distance in the dead silence of the empty city. Then, Zhang Heng hurriedly closed the window, and at the same time hid behind the wall, cautiously looking out of the window!

In just half a minute or so, four or five zombies came out of the dark corners and limped towards the four smashed computers, and more zombies came from farther away, but they never saw the licker.

Just when Zhang Heng thought that the licker didn't hear it, a black shadow slammed through the window, and the speed was almost only an afterimage!

Zhang Heng almost screamed, but by coincidence, the licker was rushing past the window where Zhang Heng was! Luckily, he thought that the licker would climb the wall, so he created a window that would close as soon as there was a movement, otherwise he would probably have been discovered at that moment!

Since the licker left the laboratory, Zhang Heng did not hesitate, and quickly opened the door and ran towards the top floor. Sure enough, the licker in the laboratory had disappeared, and without saying a word, he rummaged through the laboratory of three or four hundred square meters......
