After sitting on the ground and resting for a while, Chen Dong got up and picked up the hammer and walked downstairs. When he landed, Chen Dong carefully avoided the oil stains on the ground, and before stepping over the corpse of the zombie, he also picked the body of the zombie with a hammer to make sure that it was dead, and then he stepped over the corpse of the zombie with a relaxed heart.

The head was smashed into mud by a sledgehammer, if the zombie is not dead, then the vitality of this alternative creature is really a bit intolerable!

He walked cautiously to the first floor, and when he saw the closed security door of the unit building, Chen Dong breathed a sigh of relief.

In fact, Chen Dong has always been worried about whether the security door is closed, if the door is open, then there may be more zombies coming in, if there are zombies coming in in the process of smashing zombies with a sledgehammer, the consequences are really unimaginable......

After confirming that the security door of the unit building was closed, Chen Dong wanted to go up to the second floor to go home, but as soon as he walked up two steps along the stairs, he suddenly felt a thrill in his heart, and even broke out in a cold sweat.

In order to deal with the zombies at the door, he did calculate a lot, but he forgot an important detail that could be fatal, and he forgot to rule out the possibility that there would be zombies upstairs to attack him.

Chen Dong's unit building has a total of eight floors, and his house is on the second floor, since there are zombies wandering on the first and second floors, will there be zombies wandering on the stairs upstairs?

However, according to the current situation, Chen Dong's luck is very good, there are no zombies upstairs, otherwise when he smashed the zombies with a sledgehammer just now, the movement should have attracted the zombies a long time ago.

After all, I don't have any experience in this area, I don't have enough experience, and I can't think about it at all! Chen Dong secretly told himself in his heart that he must be careful in everything in the future, otherwise his life will be over sooner or later!

After all, according to Chen Dong's current observations, zombies are completely able to judge the location through hearing, and the zombies' hearing is absolutely unusually keen! When throwing the oil drum just now, the old lady zombie was stimulated by the sound of the oil drum falling to the ground, and then quickly pounced from downstairs. In the room, when Chen Dong threw the rats in the cold water cup downstairs, the group of corpses rushed to chase and kill when they heard the sound, which should also be because they heard the sound of the cold water cup breaking.

However, how did the zombies downstairs determine the route of the rat's escape at that time? Could it be that zombies also have a sense of sight or smell, and can clearly accept all the news of the outside world?

Although Chen Dong had basically determined that there would be no zombies on the staircase upstairs, he still picked up the hammer and walked upstairs in line with the idea of life first and being cautious.

He had to make sure if the building was safe because he had his own ideas. His idea was simple and realistic, if he could be sure that the entire building was safe, then wouldn't all the food stored in the homes of all the residents in the whole building be his?

Anyway, the electricity hasn't been stopped recently, and although the weather is hot, the food in the refrigerator won't spoil.

Carrying a hammer, Chen Dong vigilantly went up the stairs all the way to the fifth floor, Chen Dong did not find any zombies, but the security doors of each house were also closed. It's a good thing that there are no zombies, but when Chen Dong saw the closed security door, he still had a headache.

How do you open this closed security door? Can you smash the door open with a sledgehammer in your hand?

"Bang, bang."

Just when Chen Dong was depressed and wanted to go up to the sixth floor, the security door of the fifth-floor resident suddenly rang a few times, and the frightened Chen Dong immediately retracted the foot that had just stepped on the steps, and took two steps back suddenly.

"Whew!"

Inside the door, there was a sudden roar, Chen Dong heard it clearly, and he was so frightened that he almost sat on the ground, and inside the door was clearly the cry of a zombie.

There are zombies in this household!

The security door is obviously closed, how did the zombies get inside? Chen Dong wondered for a while, the zombies in the door may have been aware of Chen Dong's existence, the originally coherent knocking sound turned into a crashing sound, and it was also accompanied by the harsh sound of fingernails scratching the door, and the entire security door shook slightly.

Chen Dong boldly approached the anti-theft door, slapped twice on the door, and then gently slammed it on it with a hammer, after the anti-theft door, the zombie's reaction became more intense, and the howls were also connected, but this zombie could only roar anxiously inside the door, and couldn't come out at all.

Zombies won't open the door, Chen Dong's careful temptation came to the conclusion that the person who turned into a zombie really only retained his ferocity, and did not have the slightest wisdom at all.

Chen Dong has been observing the zombies downstairs for the past few days, in fact, he has already guessed this, and now he just wants to confirm it.

Since the zombies in the house can't get out, let's let him go for the time being, glancing at the slamming security door, Chen Dong carried a hammer to the sixth floor. In order to prevent the heavy material of the burglar door, it is definitely not something that zombies can use brute force to knock open, zombies are noisy, if you like to hit it, go and bump it, Chen Dong muttered in his heart, the stupid zombie in the room had better hit himself to death!

After tossing around on the fifth floor, and making a lot of noise, Chen Dong knew that there would definitely be no zombies upstairs. However, Chen Dong still carried the hammer all the way up to the eighth floor, and even walked around the stairs with the ninth floor attic, and after making sure that there was no zombie, he felt safe and a little safe.

Standing at the door of the security door of the occupant on the eighth floor, Chen Dong leaned his hammer against the wall and looked up and down at the security door, thinking about how to break the door open and go in to find food. The material of the anti-theft door is generally stainless steel, the quality is very good, if you want to break a hole in the door, it is impractical to use Chen Dong's existing tools, the real way is to think about the door lock or door folding, after all, these two positions are the weak points of the anti-theft door.

Looking at the doorknob, Chen Dong knew that it was the approximate location of the lock cylinder, but Chen Dong had never made an anti-theft door, and he didn't know the detailed structure inside the door. The only tool that Chen Dong can use now is the sledgehammer at hand, and he gestured back and forth at the position of the doorknob a few times, thinking about whether to use the sledgehammer to try a few times at this position first.

casually touched the sledgehammer on the wall, Chen Dong's fingers just touched the handle and wanted to hold it, but unfortunately, the sledgehammer handle was flicked by Chen Dong's fingers and tilted outward, he didn't pay attention to it, failed to catch it, and the sledgehammer fell directly to the ground.

The wooden handle fell to the ground, making a crisp sound that was not loud, and he didn't care, he bent down to pick it up, but at this moment, in the security door he was facing him, there were suddenly several hurried footsteps.

"Whew!"

At the same time, the howl of zombies came from inside the door. The zombies in the door may be wandering in the living room, not far from the security door, Chen Dong only heard four or five heavy footsteps later, there was a loud noise inside the security door, and the zombies in the door slammed into the security door.

There are zombies in this household! The surprise in Chen Dong's heart only flashed, and then immediately turned into horror. Because, he heard an incomparably clear sound of a spring beating, which was the sound of the door lock opening.

Zombies will actually open the door!!

didn't care about the sledgehammer at all, Chen Dong directly pounced on the security door that had just opened a crack, and the collision sound he made was louder than when the zombies in the room hit the door.

The anti-theft door that had just been opened was knocked back by Chen Dong, and the crack of the door was only opened to a width of a palm, and the zombies inside naturally couldn't get out, but unfortunately, one of the zombies' hands didn't know when to take advantage of the gap when the door was opened, Chen Dong knocked the door back, squeezed the zombie's hand, and the door was not closed tightly at all.

"Damn, the zombies will open the door and pour blood mold!"

Chen Dong scolded angrily, even his face was attached to the door, his head and body were forced, and the zombies in the house pushed the door together, trying in vain to close the door, but as the zombies in the door kept howling, Chen Dong felt more and more pressure.

The security door was opened outward, and the zombies inside the door slammed the door with various parts of their bodies in pain, and Chen Dong could only push it in. Chen Dong tried his best, but he still couldn't stop the door opening bigger and bigger, and the zombies in the room were much stronger than him.

Chen Dong and the zombie were in a stalemate for two or three minutes, he felt that the strength on his body was getting smaller and smaller, but the zombie inside the door didn't know that he was tired at all, and the force of pushing the door was getting bigger and bigger.

"Whew!"

The howl of the zombie sounded in his ears, and the zombie in the door had already stretched out his head, and Chen Dong, whose face was close to the door, came face to face with it, and Chen Dong, who was frightened, almost lost his strength.

"If he goes on like this, he'll have to come out and eat me sooner or later, damn it, fight for it!"

Looking at the hideous face of the zombie, Chen Dong roared angrily, no longer pushing the door hard, but following the force of the zombie pushing outward, he slammed the doorknob outward, and the zombie immediately stumbled and rushed out.

Seeing the zombies rushing out, Chen Dong deliberately retracted his strength, and when the door was halfway open and the zombies just came out, Chen Dong used all his strength to slam the door inward.

The zombie hit the security door pushed by Chen Dong, his steps were unsteady, and he almost didn't fall down the stairs. The zombie hit the anti-theft door, and a huge force came from the door, Chen Dong grabbed the doorknob and pushed the door, but he was also hit backwards by the force from the door.

The wall facing the stairs is the elevator door on the eighth floor, and the security door was completely opened by Chen Dong pulling the door handle, and Chen Dong's back also hit the elevator door.

Chen Dong barely fell, but the zombie had already reacted and turned his head to pounce on him.

Chen Dong leaned his back against the elevator door, he didn't have time to be afraid, with a loud roar, he quickly raised his foot and kicked hard towards the zombie's abdomen.

The zombie was kicked out directly by Chen Dong, and behind the zombie was the staircase, and without accident, the zombie rolled down the staircase. At this moment, Chen Dong saw the opportunity, the ferocity buried deep in his heart was about to move, the blood was up, Chen Dong's mind was a little dizzy, at this moment, Chen Dong had only one thought hovering in his mind, that is, he felt the sledgehammer and smashed the zombie's head!

However, the zombie who rolled down the stairs didn't give Chen Dong a chance at all, the zombie's back was against the stairs, but it slid down a little and stopped there, the zombie struggled, and there were already signs of getting up.

This zombie's reflexes and limb dexterity are much faster than the old lady zombie!

Looking at the fast-moving zombies, Chen Dong's sledgehammer had just picked it up, so he decisively let go and gave up, dodging and rushing into the wide open door.

"Bang!"

Chen Dong quickly closed the security door, and the zombie had already gotten up and rushed to the door, but the zombie was a step slower after all and was locked out.

The sledgehammer is too heavy, the speed of the zombie is too fast, Chen Dong is very clear about his strength, he can't grab the zombie before he pounces, and he can't guarantee that he can put the zombie down with a hammer.

Sure enough, not everyone can use a hammer as a weapon, although Chen Dong thinks he has the strength to do it, but swinging a sledgehammer will also affect the attack speed, and he can't be flexible and free. The sledgehammer is okay to deal with the abused zombies, but if you fight with the zombies face-to-face, with Chen Dong's physique, you can't react at all.
