As a predator, the puppy has its own way of hiding its breath, otherwise with its strong vitality, it will not live long if it appears anywhere without shelter.

Wu Zhen's current state is very wonderful, his breath is very weak and long, and the time of one breath is extended to four or five seconds, which is not a breath-holding method, but it is a very close feeling.

The breath-holding method is very harmful to the body, especially to the heart, but this is different, this is a shallow degree of breath-holding, by controlling the respiratory system, slowing down every action to the minimum, the effect is not as good as the breath-holding method, the advantage is that it will not be so extreme, there is almost no harm to the body, and it can last longer, the only feeling is uncomfortable, and the feeling of breath-holding is always so painful.

After waiting for almost half a minute, Wu Zhen suddenly perked up, and the thing he was waiting for came.

In the hallway, a bulky figure was walking outward, his steps were slow, his movements were stiff, and his eyes were shining red in the dark, this was a lone red-eyed zombie.

The zombie stopped for a while when he walked to the place where Wu Zhen was staying before, and just when Wu Zhen thought that something across the wall had found him, the zombie left.

Da-da-da-da!

Hearing the footsteps gradually moving away, and it was still in the direction of the outside, Wu Zhen felt a little relieved, it seems that the IQ of the things outside is not high, it is likely to be something like a zombie, if it is a predator, it is estimated that there is no such stupid type.

When the voice was so weak that it was almost inaudible, Wu Zhen walked out with the puppy in his arms, the puppy's nose moved, and sniffed the front and back of the corridor, the familiar smell made it feel a lot more uneasy, the zombie is not the opponent of this puppy.

Although Wu Zhen's nose is not as good as a puppy, he can also smell the rancid smell in the air that has not yet dissipated, and immediately recognized that this is the exclusive smell of zombies, zombies may come back at any time, maybe there are more zombies on the way inside, this place can't stay for a long time.

Following the feeling in his memory, Wu Zhen groped to the location of the staircase, held on to the handrail, and slowly walked to the second floor.

The position of the staircase, Wu Zhen stopped, shrank in the corner, ready to adjust the state, he couldn't hide when he went to the second floor, in order to find something, the battle was inevitable.

Zhang Xin's location is on the second floor, which means that after Wu Zhen goes up, he must go from room to room to look for clues, and in the process, he may encounter any creatures, for him, they are all enemies.

After thinking about it a little, Wu Zhen felt a headache, the probability of Zhang Xin being alive was too low, he didn't think that he could find her on the second floor, whether it was dead or alive, after countless thoughts, he had accepted the result, however, he still wanted to take a look, maybe he could find any evidence, preferably evidence that could prove that Zhang Xin was still alive, and that's all he needed.

The end of the world happened in the afternoon, and it was work time, and Zhang Xin was likely to work in the company at that time, and the probability of being at home or elsewhere was low.

After the dust, there are several possibilities for Zhang Xin's state. It is possible that he has become an evolutionary, or he is still an ordinary person without changing, and the probability of the above is low, and the most likely is that he has mutated into a zombie.

If you become an evolutionary, it is too difficult to escape from a place where there are many zombies, but it is also possible that if you are a zombie and have not been killed by humans, you may have escaped with other zombies, and then melted into the zombie team.

What Wu Zhen is looking for is evidence, and there must be evidence for life or death.

Knock knock!

The sound on the first floor was clearer and messy, and it seemed that more things had gathered, and it was initially judged to be zombies.

Wu Zhen didn't wait any longer, put the puppy on the ground, and quietly touched it.

The second floor is Wu Zhen's battlefield, and the first floor is given to the puppy.

The breath of human beings is the most attractive thing for zombies, which is the fatal temptation ~ confusion of the soul level, if the zombie has a soul.

Smack! Smack!

Something went upstairs.

The puppy stuck out its tongue and coughed a few times, and its little body trembled. The smell made it uncomfortable and it excited, and subconsciously, it thought that the smell of zombies was terrible, but there was a voice that kept telling it that it was the source of evolution, that was food.

The sun had risen so high that except for the lowest floor, the other floors were gradually occupied by sunlight, and at the staircase from the first floor to the second floor, the sunlight crept in and could no longer climb after falling on the puppy's back.

Behind the puppy is the warm sun, and there is still endless darkness in front of it.

The puppy takes a few steps back, bathes in the light, raises its little paws, gently plows the ground, and sneers! The smooth floor was scratched with a few ugly marks, and a white shadow flashed, turning into a black shadow in the moment it jumped into the darkness, and then there was a muffled sound in the darkness.

Swish!

The puppy re-entered the light, with a bloody lump of flesh still attached to his mouth.

A zombie is dead, but the battle hasn't even begun. In the darkness, more voices came out, and excited howls were carried through the staggered corridors, all the way to the puppy's ears.

The taste of zombies is really not good, after all, it is rotten meat that has been rotting for a long time, not to mention the chewiness, and it is particularly soft and disgusting, but it is also a zombie, and it contains a lot of energy, and it is enough to have energy.

The puppy tilted its head, listening to the zombie's roar, something in its heart was ignited, and it opened its mouth slightly, spitting out a frightening word.

"Wang!"

Second floor.

The light is a little dim, but it is much better than the first floor, the sunlight penetrates through the glass, doors and windows, so that the darkness is no longer so pure, the further you go inside, the darker the light becomes, and the darkness in the depths makes the sunlight powerless.

It would be nice if there were lights.

Wu Zhen stood next to the entrance, stretched out his hand, and his fingertips touched the switch.

Subconsciously pressed.

Click!

The switch is on, and the darkness remains.

Wu Zhen laughed dryly, knowing that he was thinking too much, electricity was a thing before the end of the world, and it was difficult to build without a complete system, and any of the links were destroyed by zombies and other things, and in the end, there would be no electricity.

Now I am afraid that it is difficult to see normal electrical appliances, because the power supply bureau may have become a nest of zombies.

The excited howl of the puppy and the neighing of the zombie before death were mixed together, Wu Zhen shook his head and drove those sounds away, the puppy's battle did not need him to worry, he should worry about himself.

Through the light, Wu Zhen can see some scenes of the office on the second floor.

Desks and chairs, paper strewn everywhere, broken chandeliers, and dried bloodstains.

Almost everything was stained with blood, and this scene was so common that it could not be called the end times without blood.

However, there was something else besides blood, a desk that trembled slightly.

Wu Zhen was frightened, and slowly walked into the desk that made a movement, the closer he got to Wu Zhen, the more nervous he became, and he always felt unusual.

Bang!

The loud sound startled Wu Zhen, who was nervous, and when he looked up, the desk actually collapsed, and the contents were exposed in front of Wu Zhen.

What the hell is this?

Wu Zhen's feet were trembling, his reason was almost overrun by fear, and he wanted to run away.
