"Sister Jin, be careful!"

"Made.... How can there be so many zombies on this level! ”

Chen Fei scolded in a low voice, and rolled vigorously to pick up the crossbow that had fallen to the ground.

Chen Fei knelt on one knee, took a deep breath, held his breath, and calmly pulled the trigger twice in a row.

Sou... Sou....

With the continuous pull of the trigger, two stainless steel crossbow arrows shot through the heads of the two zombies with precision.

Without the threat of the other two zombies, Nangong Jin let out a low shout, and the long knife slashed through the neck of the zombie in front of her, and then the zombie's movements stopped abruptly, and after a few shakes of the body, a head fell to the ground and rolled to the side, and the already straight body also fell heavily to the ground.

There were no zombies to pounce on, and in the corridor of the elevator room, except for the sound of violent breathing, only the sound of the fire door being slammed hard.

Chen Fei and Nangong Jin glanced at each other, nodded slightly and walked vigilantly towards the room at the end of the corridor.

This layer is the most miserable layer that Chen Fei and Nangong Jin have ever seen, it is really like purgatory, the walls on the ground are full of splashed blood stains, drag marks, and rows of bloody handprints, which seems to be narrating the tragic scene to Chen Fei at that time.

The doors of 2002 were closed, while the doors of 2001 were wide open.

Chen Fei and Nangong Jin kept their steps as light as possible, and after finding that there were not many arrows in the crossbow, Chen Fei took out seven stainless steel crossbow arrows from the quiver behind him with his backhand and reloaded them.

As 2001, which may be the first scene of the tragedy, Chen Fei couldn't help but gasp when he saw the scene in the living room, there were dried blood and minced meat everywhere, and the splashed blood even splashed to the ceiling, and there were two zombies with incomplete limbs and mouths lying on the floor of the living room.

Their bodies can only be described as fragmented, one of the zombies' legs and left arm have disappeared, judging from the rotting wounds, it should have been torn alive, and the only remaining right arm is just a little rotting flesh and white bone.

The one-armed zombie with its abdomen and chest hollowed out not far from this zombie may have a broken spine, and it was lying on the ground unable to move, and the only remaining left arm was clutching the air indiscriminately.

After Chen Fei and Nangong Jin entered the room, the two zombies also became active, but because of the limited movement, they twisted their necks wildly.

Chen Fei and Nangong Jin searched the room in the house first to make sure that there were any other zombies, and after confirming, Chen Fei returned to the living room, using the M9 multi-function bayonet to pierce the eye sockets of the two zombies and then stir it, which would save a lot of effort than the position of the skull.

There is a birthday cake on the coffee table in the living room, and on the wall behind the sofa, the words happy birthday are pasted with balloons, seeing these Chen Fei finally understands why there are so many zombies on the 20th floor, thinking that a birthday party is being held here when the virus breaks out, it is no wonder that these zombies are thin and young and fashionable.

Chen Fei breathed a long sigh of relief, and sat directly on the sofa regardless of the coagulated blood stains on the sofa, and easily smeared the viscous blood adhered to the M9 multi-function bayonet on the sofa.

Nangong Jin's face had an abnormal flush because of the battle just now, which made people can't help but emerge after watching it, Chen Fei noticed the entanglement of Nangong Jin's expression, after all, women love to be clean, although there are blood stains on her clothes, but not like Chen Fei, half of her body is stained with fishy blood.

The sofa is a more casual fabric sofa, Chen Fei thought about it and turned over the cushion of the sofa next to him, although there were blood stains on the top, but the bottom was still very clean.

Chen Fei patted the sofa with his hand to signal, and Nangong Jin snorted lightly and walked over here and sat down.

"It's just that a few zombies make us so embarrassed, there are thousands of zombies on the street outside, and it is estimated that there are not even bones left to be gnawed," Chen Fei shook his head and said self-deprecatingly.

"But.... Aren't we alive now? And we have a good food stockpile, and there is no problem with eating for a year or two, how? With such a big beauty as your sister, you have already been happy in your heart! Nangong Jin's tone carried a hint of mockery, but from her eyes, Chen Fei couldn't see the purity before, mixed with a trace of sadness.

It's no wonder that Nangong Jin is like this, who thinks that his parents have prepared enough, but one of the parents broke out of the zombie virus and became a zombie, and then bit the other person to death, and finally became a zombie couple, they can't accept this ending, in Chen Fei's opinion, Nangong Jin can hold back so many days without crying, behind the strength is endless sadness.

Although he experienced a rather thrilling battle on the 20th floor, Chen Fei's harvest was not small, of course, this harvest was not about the materials in room 2001, but the number of these zombies, which made Chen Fei closer and closer to the goal of killing 50 zombies.

After resting for a while, Chen Fei and Nangong Jin left one after another 2001, Chen Fei shot the crossbow arrows of the zombies in the stairwell for a while, he couldn't recover them for a while, he could only wait for a while to lure the zombies blocked outside and then go, although Chen Fei had two hundred stainless steel crossbow arrows in his hands, but now was not the time to consume crossbow arrows, he had to be careful and take precautions.

Because there are too many zombies to fit in the bathroom, Chen Fei dragged the corpses of these zombies into the master bedroom of 2001, and opened all the windows for ventilation, otherwise the rotten smell of these corpses can directly choke people to death after a long time.

Chen Fei walked to the door of 2002 and knocked a few times, the room was very quiet, there was no survivor's cry for help and no zombie howl, Chen Fei could only use the unlocking technique to open the door, with the experience of the previous car, Chen Fei and Nangong Jin were obviously more cautious when opening the door, so as not to be caught off guard again, they could get lucky this time, but it doesn't mean that they can be just as lucky next time, so they must be cautious.

After the door opened, Chen Fei found that it was a false alarm, the room in 2002 was very simple from decoration to furniture, and he searched for a circle in each room, and he was able to basically determine that the room had not been lived in for a long time, and the kitchen was only half a bag of rice, half a barrel of oil, and the refrigerator and TV and other electrical appliances were not even connected to the power supply.

After that, Chen Fei first went down to the 14th floor to attract the zombies in the stairwell on the 20th floor, and then took the elevator back to the 20th floor, and after quickly recovering the crossbow arrows in the stairwell, Chen Fei and Nangong Jin walked lightly to the 21st floor......

When the time came to eleven o'clock, Chen Fei and Nangong Jin had already cleaned up to the 23rd floor, and the intensive battle consumed a lot of the two, except for one survivor on the 21st and 17th floors, the other floors were all zombies as masters.

Because the survivors on the 21st and 17th floors have a good attitude, Chen Fei left them with some of the living materials in the house opposite them, on the one hand, the unquenched sympathy, and on the other hand, it is really tiring to collect all the materials in these floors at one time.

......

Lunch, Chen Fei and Nangong Jin ate at Grandpa Zhang's house on the 12th floor, although the two old people are old, but the body is still very tough, Grandma Li spent a morning to wrap a pork and green onion stuffed dumplings for Chen Fei and Nangong Jin, this is the most sumptuous meal that Chen Fei and Nangong Jin have eaten in recent days, Chen Fei's gobbling up the meal made Grandma Li's face full of loving smiles.

After eating a hearty lunch, Nangong Jin returned to his home on the eleventh floor to rest, and just after eating, he fell asleep Chen Fei was really afraid that Nangong Jin would implement a fat-raising plan in the last days, and then become a XXL large-sized beauty.

Chen Fei did not return to the 11th floor, but patrolled around the 12th floor to ensure the safety of the 12th floor, Chen Fei moved all the things that could be moved in the 1201 home to the fire door on the other side of the elevator corridor, which was used to resist the fire door.

At half past one in the afternoon, Chen Fei and Nangong Jin started a new round of cleanup operations.

Chen Fei did this to kill zombies and do tasks to activate the apocalyptic domination system, Nangong Jin was afraid that Chen Fei would become a zombie's rations, and on the other hand, she also wanted to hone her combat ability, she had to prepare for the worst, and be prepared for a long time when this catastrophic virus would last for a long time.

The clean-up battle went smoothly, and it only took an hour and a half for Chen Fei and Nangong Jin to clean up to the top floor, where they only encountered zombies and no survivors.

Just imagine..... When your neighbor who has a good relationship knocks on your door with a bloody wound that has been bitten and asks you for help, most people will choose to open the door and let the neighbor in out of human sophistication, especially if your neighbor is still a beautiful and lovely young lady, or a mature and charming big sister, it should be more difficult to refuse.

And this is the origin of the tragedy, from the tragedy of one family to two families, so there will be a result of two families on one floor and two families becoming zombies, of course, only the parties themselves know what the cause of the incident is.

As for the floors on the sixth floor and below, Chen Fei and Nangong Jin had no intention of cleaning them up, mainly because the floors were too low and the speed at which the zombies gathered was too fast, and there was a high chance that they would be attacked from three sides, so they had to make a cautious decision.

What made Chen Fei very unhappy was that he hadn't killed enough of the 50 zombies needed to activate the system, but Chen Fei thought about it 12 years later, when he got the system, it was estimated that no one would tell him in advance, since the kind of unprepared self could kill 50 zombies, let alone himself who was now fully armed.

However, Chen Fei didn't know that 12 years later, the task condition for him to activate the system was just to carry the virus into the body for 24 hours, and as for killing 50 zombies, this was the variable in his mouth 12 years later.
