Even without cheats, we must survive the apocalypse

"...I hope this heavy rain will stop soon..." He thought, he had found the best time to escape from here.

The sound of rain and thunder can conceal their footsteps, and the rain can cover up the smell on their bodies. When the heavy rain falls, it will be time for them to escape from here!

Of course, all this is based on the assumption that zombies really rely on these senses to detect prey. Without systematic research on the specific ecology of these ghosts, who knows whether they will evolve some more bizarre senses - but they have no choice but to accept it! This is a cruel doomsday world, and there is no completely correct and risk-free option anymore.

Now, it depends on whether the heavy rain falls first or the monster upstairs strikes first...

"Su Xin, I need to talk to you," Chu Xiao knocked on the door of the laboratory classroom and whispered, "I have some ideas about the timing and route of leaving here..."

……

At this moment, in the breeding room on the third floor, the blood cocoon composed of living people finally stopped rising and falling like a heart, and the living people that made up the blood cocoon had been melted into a layer of fragile skin.

Hundreds of blood-red rats crawled out of the blood cocoons one after another. They crept quietly on the ground, with hundreds of scarlet eyes shining coldly in the dark. All the blood rats stared at the huge blood cocoon, as if they were waiting for the queen to break out of the cocoon.

It has become a thin layer of blood cocoon, with a crack appearing...

Chapter 19 Blood Rat

"what are you doing?"

After conveying his thoughts, Chu Xiao couldn't take his eyes off the desk in the classroom.

"Just as you can see." Without even turning back, An Suxin carefully poured the liquid in the flask into a brown bottle.

The light from the alcohol lamp illuminated the small space in front of the desk. The entire desk was filled with various bottles and jars. She had almost emptied the chemical reagent cabinets in several classrooms. The air was filled with the pungent smell of chemicals.

Chu Xiao looked curious and reached out to grab a sealed bottle to see what was inside. But An Suxin shouted at him, "Stop! Don't you want your hand anymore?"

He immediately retracted his hand, looked at An Suxin, who looked like a witch in a fairy tale, and asked in a low voice: "What is that?"

"Nitroglycerin."

Chu Xiao, who had been out of school for many years, subconsciously thought about what this thing was. When he gradually remembered the high school chemistry knowledge that he had almost forgotten, his hands trembled subconsciously and he couldn't help but screamed out: "What the hell?"

"Nitroglycerin, also known as glyceryl trinitrate."

"I know! It's the dangerous stuff that Uncle Nobel made!" Chu Xiao was a little crazy, "It's dynamite! How can there be such dangerous stuff in a high school laboratory nowadays! Don't those people in the school care?"

"Of course it's not ready-made." An Suxin carefully sealed the last bottle of nitroglycerin. "I emptied out an entire floor of reagent cabinets to prepare this little bit. Didn't I tell you that I majored in science in high school?"

Chu Xiao silently complained in his heart: No, a normal science student wouldn't prepare such dangerous goods...

"I remember when I was in a desperate situation, I really considered making some small things and sending them to the debt collector, but unfortunately the owner of the reagent store refused to sell them to me...Okay, everything is done." An Suxin carefully handed the sealed bottle to Chu Xiao and warned, "Don't shake your hands. This thing will explode immediately if you move violently. This dose should be enough to make you lose your entire arm. Just think of it as a simple fragmentation grenade."

Looking at the small brown bottle in his hand, Chu Xiao thought quietly in his heart: Fortunately, this world ended before An Suxin became a dangerous person, otherwise she would have to go to jail one day.

Chu Xiao thought about it and decided to hand these "dangerous goods" over to An Suxin for safekeeping. It was not because he was afraid, but because the woman was careful and the risk of accidental explosion was too high if they were left in his hands.

At this time, the door of the experimental classroom was knocked again. When the door was opened, Su Muhe was seen standing in front of the door with an anxious look on his face: "Brother Xiao, Mengmeng said she heard something bad."

Chu Xiao followed Su Muhe to the other end of the corridor and saw Ruan Mengmeng put her ear against the wall to listen carefully.

The location here is right below the breeding room.

"Brother Xiao, that thing seems to be moving." She heard countless rustling sounds, as if a bloodthirsty army was gathering.

Chu Xiao was anxious. He looked out the window, but there was still no heavy rain.

The two girls looked at Chu Xiao, and even An Suxin looked over. The secretary held Chu Xiao's hand tightly, so hard that even her knuckles turned pale.

Chu Xiao suddenly realized that no matter how powerful and outstanding An Suxin was, she was still a girl who had just graduated from college. No matter how strong and wise she appeared, she would still be afraid. And he, Chu Xiao, was now the oldest and only man in this small team. He had to be the support of these girls.

"Suxin, Susu, Mengmeng, take my sister to the window on the other side and gather there. If it starts to rain, go down through that window. I'll go check at the stairs!"

The reason why we chose the classroom at the end of the corridor was because there was a ready-made drainage pipe on the wall over there, through which we could crawl down, and there was a flower bed right below the window, which could prevent us from being noticed by the zombies to a certain extent.

"I'll go with you." Ruan Mengmeng tightly grasped the samurai sword that Chu Xiao gave her, "I should be able to help."

Now was not the time to be polite, so several of them immediately started to act separately.

Chu Xiao brought the riot shield found in the security room to the stairwell door that he had sealed. He looked through the tempered glass on the door into the dark corridor. It was pitch black, as if there was nothing. At this moment, a strange blood shadow suddenly jumped up and hit the door glass!

There was a loud bang and the whole door shook a few times.

As Chu Xiao had guessed, there were several rats that were too big, blood red all over, as if they had been soaked in blood! They were seen slamming against the tempered glass, constantly showing their fangs at Chu Xiao, and the sharp teeth rubbed against the glass, making an extremely harsh sound.

A huge sense of crisis hung over Chu Xiao's heart. The aggressiveness and strength of these blood-colored rats were astonishingly great. They fearlessly attacked the tempered glass, as if a tide was hitting the stairwell door!

The hard tempered glass was soon hit and had terrible cracks.

"Meng Meng! Go get the tape!" We must not let these rats rush in now, or they will have nowhere to retreat! At least, we have to hold out until the rain starts!

"Come here!"

When Chu Xiao used tape to reinforce the cracked glass, he looked through the cracked glass and his scalp suddenly went numb! In the dark corridor, he saw dense red eyes, like bloody lights. Those eyes looked at him, and he could even read the manic and bloodthirsty instincts in them!

It was like an army ready to go, just waiting to break through the obstacles, and then rush out like a mad wolf to tear the humans in front of it into pieces!

However, he had a feeling that something more dangerous was still lurking in the darkness!

The glass reinforced with tape couldn't hold out for long, and soon a blood rat bit through the barrier and pounced on Chu Xiao. Chu Xiao picked up the riot shield and swung it hard. His muscles were tense, and the force he exerted was much greater than before. With just one blow, he smashed the blood rat against the wall, turning it into a pool of minced meat.

Chu Xiao didn't have time to marvel at how amazing his strength had become, because more blood rats were crawling in from the hole!

"Be careful not to get bitten!" Chu Xiao warned loudly - there was no point in keeping quiet at this time.

"Understood!" Ruan Mengmeng quickly drew her sword and accurately cut off the blood rat in mid-air. Her movements were skillful, and she must have practiced kendo before. She used a gorgeous samurai sword weighing about one kilogram very easily and skillfully.

Chu Xiao was very glad that he gave the knife to Ruan Mengmeng to use.

With the help of the girl, the two of them managed to hold off the blood rats. The number of rats that could get in through the cave was limited. Although these monsters were fierce, they were not a big threat as long as they did not rush in all at once.

However, soon the blood rats gave up the attack, a strange scream was heard, and the blood rats retreated like a tide.

Chu Xiao did not relax, but became more nervous - judging from their performance, these damn rats had someone behind them! They were not demented monsters at all!

"Ah!!!" A scream suddenly rang out, causing Chu Xiao's expression to change suddenly.

——This is Su Muhe’s voice!

The two of them hurried towards the direction of the scream, and saw that the window glass at the end of the corridor on the other side of them was densely covered with bloody rats!

——These weird rats actually know how to make a feint to the east and attack in the west!

There was a loud clanging sound, and the window glass shattered to the ground. Countless bloody rats rushed into the second floor!

Chapter 20: Desperate Situation

Chu Xiao didn't have time to hesitate. He rushed over and picked up his sister, shouting at them, "Go into the classroom! Quick!"

The blood-red wave almost instantly covered the walls of the corridor, and the shrill squeaking sounds gathered into a terrifying sound wave that made people's scalps tingle.

Several people immediately rushed to the nearest classroom, but the rats were so fast that they seemed to be close to their faces in an instant!

At the critical moment, An Suxin decisively threw out a small brown glass bottle. The moment the bottle fell into the center of the rat swarm, it exploded violently, and the glass fragments produced by the explosion flew in all directions, causing a large number of casualties in the dense rat swarm. This sudden explosion effectively slowed down the speed of the rat swarm, but the scattered fragments could not identify the enemy.

At the moment of the explosion, Chu Xiao decisively leaped forward, protecting the four girls with his back, and rushed into the classroom, enduring the severe pain from his back. Then, regardless of the pain, he immediately got up and closed the classroom door tightly.

"You're hurt!" There was a hint of panic in An Suxin's tone.

"It's no big deal! This just shows that what you make is indeed reliable!" Chu Xiao felt a burning pain on his back. Fortunately, he was wearing a thick stab-proof suit, so the wound should not be too deep and would not affect his current actions.

This was definitely not the time to relax. The explosion just now could not kill all the blood rats. More blood rats filled the gap and rushed towards the classroom again. The windows facing the corridor were soon covered with ferocious and hideous rats. This fragile window could not block this group of weird rats for long, but at least it gave them some time to breathe.

At this critical moment, Chu Xiao felt his blood getting hotter and his brain was thinking rapidly. Even the severe pain in his back could not hinder him at this moment. Instead, it stimulated his nerves, making him more awake... and more fanatical!

He remembered this feeling, he had it before when he smashed the zombie's head!

At this moment, the thunder in the night sky outside the window was getting closer. The rumbling thunder spread in the dim sky, and the anger between the clouds seemed to have brewed to its extreme!

A downpour could fall at any moment!

Chu Xiao asked the girls to retreat to the window on the other side, and handed his sister to Su Muhe's care. He loudly directed the girls around him: "Push down the desks and use them as shelters! Get well! Suxin, wait for those rats to rush in, and use your 'grenades' to hold them off first. Mengmeng, after the grenades are used up, you and I will go together, and we must hold out until the rain stops."

The location of the shelter is in the corner near the window. Chu Xiao thought clearly that at this time, the fewer areas that need to be defended, the better, to ensure that they will not be attacked by the blood rats. When the time is right, they can jump directly out of the window.

However, downstairs was an open grassland with quite a few zombies around. If one went down directly, it would be like jumping into the zombie swarm, and the outcome would definitely not be much better than being swallowed by a swarm of rats.

"Desperate situation?... Let's take it one step at a time! Let's fight!"

Chu Xiao turned on the lights in the classroom - this was no longer the time to worry about the lights attracting zombies, fighting these rats in the dark was too disadvantageous for them. Under the bright light, cracks appeared on the window glass, and those hideous little monsters became clearer. Chu Xiao could even see their weirdly strong muscles, overly sharp fangs, and fur that seemed to be soaked in blood.

The bloody rats did not leave them much chance to breathe. The window glass of the classroom was soon smashed, and the crazy rats rushed towards them in an instant!

"leave!"

An Suxin did not hesitate and threw the nitroglycerin in her hand towards the densest area of ​​the rats. The violent explosion blew the fragments of the blood rats' bodies into the air. The violent explosion and the scattered fragments seemed to interfere with the blood rats' attack to a certain extent.

However, after a brief period of confusion, there would be another strange scream, causing these damn rats to resume their offensive, just like a group of attacking soldiers hearing a morale-boosting horn!

They don't seem to be moving corpses like zombies, but living creatures, so they can be killed without destroying their brains. However, the scary thing is that there is obviously an intelligence behind them that controls everything.

Chu Xiao didn’t know how terrifying that unknown existence was, but he didn’t want to face it at all.

An Suxin had used up all of her "simple grenades", and the table in front of them was covered with a dense layer of glass fragments.

The violent explosion killed a large number of blood rats, but more were injured by the scattered glass fragments and lost their ability to move.

The blood rats' attack was temporarily eased, and the number of blood rats rushing into the classroom has been controlled.

"on!"

Chu Xiao shouted, picked up the riot shield and rushed out from behind the bunker first, and Ruan Mengmeng followed without any hesitation.

At this time, the shield was much more effective than his golf club. Taking advantage of the area of ​​the shield, he swung it up and smashed it at the attacking blood rats.

In order to protect the girls behind him, he didn't dare to walk too far, and used his body and the shield in his hand to firmly protect the space behind him.

At this moment, Chu Xiao was highly concentrated, his muscles were tense, and he instantly burst out with great strength. With a violent sound of breaking wind, the blood rat that was blown away was smashed into pieces of meat on the wall.

Chu Xiao has been mentally prepared for his current strength. He and An Suxin have already guessed about the so-called "enhancement", but in the face of the impending army of blood rats, this kind of enhancement does not have much effect.

These mutated rats are obviously much more ferocious than ordinary rats. They are extremely fast and have strong jumping abilities, and can easily reach a person's head.

A blood rat climbed up the wall and attacked Chu Xiao from the side of the shield, with its sharp fangs pointed directly at his throat. The blood rat moved very quickly, but Chu Xiao's highly concentrated reaction nerves allowed him to react in time. He stretched out his gloved hand, grabbed the blood rat in mid-air, and squeezed it hard, but he failed to kill it immediately.

The blood rat showed great endurance and aggressiveness. Even after being caught, it struggled and bit Chu Xiao's hand.

Chu Xiao didn't dare to be bitten, so he threw it to the ground with force, and then stepped on it to break it into pieces.

However, this instantaneous action turned into a trace of carelessness, and he heard An Suxin behind him shouting "Be careful!". A blood rat had climbed onto the ceiling at some point and pounced towards Chu Xiao's head from above.

In a flash, Chu Xiao had no time to dodge, and in that brief moment, he didn't even have time to think.

He saw a pure white light passing by his forehead, and the sharp blade cut off the ends of his hair. As a few strands of hair fell, the blood rat that attacked from above was immediately beheaded.

When the blood rat's body fell, Chu Xiao finally realized that he had been on the verge of death.

Ruan Mengmeng exhaled lightly, then swung the knife vigorously, shaking off the blood on the knife, leaving a line of blood on the ground. Ruan Mengmeng was tall and slender, with a strand of red hair on her head, and she had a heroic aura. At this moment, she stood with the knife in her hand, just like a heroic female general in a story who was no less heroic than a man.

"Brother Xiao, are you okay?" The girl said as she kicked a bloody rat away with her long, beautiful legs that were powerful and stylish.

"Mengmeng, thank you." Chu Xiao couldn't help but glance at the girl's elastic and round long legs and praised her, "Your movements are very beautiful."

Ruan Mengmeng grinned, revealing a row of neat white teeth, but her hands did not stop moving. She took a step forward, and at the same time, the blade rose upward, slashing from bottom to top in a very beautiful arc, cutting off the two mice that pounced in mid-air. "When I was a child, I watched Rurouni Kenshin and thought the Nine-Headed Dragon Flash was very cool, so I went to learn kendo for a few years."

She didn't mention her rank, but judging by her skills, her rank must be quite high.

I've read in stories that when a powerful swordsman swings his sword with dense flashes, not even water can get in. Ruan Mengmeng certainly can't reach the master level, but her extremely neat sword flashes helped Chu Xiao share a lot of pressure. She herself was a little unbelievable and shouted in surprise: "How did I become so powerful!"

Ruan Mengmeng couldn't help but be surprised. Although she had practiced kendo before, that was many years ago. She thought she had lost her skills by now, but now that she was using a real sword, she was extremely sharp and there was no sense of sluggishness at all.

She laughed and danced the knife in her hand more frequently, cleanly and neatly like a dance of lightning. If Chu Xiao hadn't reminded her, Ruan Mengmeng, who was so eager to kill, might have rushed into the rat group to kill them.

(ps: Let me talk about this later. There are considerable changes to the plot from the first version, and a lot of details and new plots have been added. To some extent, it can also be regarded as a new work)

Chapter 21 Queen

An Suxin looked at the two people who had temporarily controlled the situation in front of her, especially Ruan Mengmeng's extremely powerful kendo skills, but there was not much joy in her eyes.
