Gray clouds suppressed the entire sky, and scattered rainflakes fell from it, making people feel cold. The ground is obscured by smog and the visibility is less than ten meters.

The city on the surface is a bit desolate, with crashed cars and smashed shops on the roads. Rain-soaked newspapers clinged to the muddy streets. Stains of red blood slid across the surface of the newspapers and billowed down the sewers.

In the sewer mixed with blood and water, the dim underground tunnel emitted a trace of white smoke, and the air was even more turbid, exuding a pungent fishy smell, and in an underground tunnel, several young men in tattered clothes ran wildly along the wall in the dim sewer, as if they were hiding from something.

After running for about half an hour, they slowed down and turned around a dark corner, and walked in, and this was a refuge they had been looking for ten days ago, it was not only remote, but there were also many escape routes, and they could run at any time in case of danger, and only then did they stop, and sat down on the damp and dirty ground at will, and at this moment they did not feel the slightest disgust and discomfort, but seemed to be lying on a soft sofa, and their whole bodies relaxed.

After a long time, the voice of speaking slowly came from the darkness, and the voice of the voice was so small, which showed that they were afraid of those unknown things to that extent.

"Chen Ji, have you advanced?"

"Yes. Not yet. This voice came from a young man sitting in the corner, his face could be seen clearly under the reflection of a ray of sunlight, the whole person gave people a feeling of embarrassment, a long hair that had not been combed for a long time stood on his head in a mess, and his face was covered by mud and could not see his face, only a pair of bloodshot eyes flashed with despair.

"Alas~ I just said don't kill that mutant rat for him, you just don't believe it, if it is for me to kill, now I may have obtained new skills."

"Don't make any noise, next time you're looking for an opportunity, let's see if there is any change in your basic data. Don't ****** die at the claws of those monsters. ”

The gloomy corridor fell silent again, and Chen Ji, who was sitting in the corner of the corridor, slowly shook his head, his face stiff and showed a bitter smile.

He closed his slightly aching eyes and saw the familiar curtain of light again, the data on which remained unchanged.

"Chen Ji; Level 1

Experience points; 0。

bodily functions; 45。

responsiveness; 30。

Velocity; 50

Strength; 60

possession of skills; Not.

System friendly reminder; Don't trust anyone around you, anyone can be your enemy. When you reach a level, the system will unlock the corresponding skills for you. ”

It's been ten days, why hasn't there been any change, Chen Ji opened his eyes and his head slowly looked like he had encountered some life-and-death but irreparable decadence.

One night ten days ago, the world was changed by a fireworks that could be seen all over the world, and all the creatures on Earth fell into a slumber for an hour, waking up as if everyone had a system implanted in their brains that would give you instructions on how to survive and not trust anyone around you!

But that night, the whole world changed, and the originally weak mice, cute cats, and all kinds of animals became invincible monsters!

Humanity has lost billions of people overnight under the attack of these monsters! The army fought against these monsters that night, but! It didn't work! The chances of human artillery fire and guns causing damage to these monsters are undetectable, and the army that used to say that they wanted to protect the country is still slaughtered by these monsters like toys.

That night the heads of state held a meeting and finally decided to use the nuclear bomb of the Lord of War! In one night, more than a dozen nuclear bombs exploded in places around the world where monsters were seriously developed, but in those places, there were still hundreds of thousands or even millions of residents who did not escape, they were abandoned by the military, and died in despair and grief, and the monsters in those areas were actually becoming more and more active under the detection of satellites, and the damage caused by nuclear bombs to them was almost zero? Instead, it has created a large area of terrifying pollution.

When the mutation began, they met in a supermarket and hid in the sewers to escape the mutants, hunting down the lone rats to advance their rank, believing that if they rose to the top, they would return to the surface sooner or later.

"How's it going?" Chen Ji raised his head and glanced at the people in the dark, pursed his lips, and then asked in a trembling voice, he was afraid that he would fall too far behind them and be abandoned by them, and at this time, being abandoned is like sentencing you to death!

"Hey, it's not much of a change, it's just that the speed has increased by two points."

"My strength has increased a little."

"I've got three more functions in my body."

"Mine hasn't changed."

"Let's rest here today, everyone takes turns to keep watch. Second, take out the rat meat you just slaughtered. ”

"Here you go."

After half a sound, a faint firelight rose from the damp ground, and in the faint light of the fire, a large chunk of bright red and dense muscle was cut into pieces by the dagger, and then handed to everyone. What fell into Chen Ji's hands was the least, only a finger-thick strip of meat.

Chen Ji looked at the slimy strip of meat in his hand and didn't complain, he threw a whole piece of meat as if he chewed hard in his mouth, the mutated monster's meat was very stiff, and it was like asking for a bone in his mouth.

The rat meat that had not been cooked in any way was full of fishy smell in the end, and there was even blood oozing out, which was difficult to swallow, but Chen Ji still resisted the nausea and swallowed the whole piece of rat meat in his stomach, and then leaned against the wall and began to look around.

Under the light of the fire, he saw that everyone's expressions were full of exhaustion, and their faces were almost white and black.

Soon he fell asleep, too tired from the previous fight, at least for him.

Until the middle of the night, he was slowly woken up, and it was time for him to be on duty for the night.

He sat by the faint fire and looked at the puddle of muddy water beneath his feet, which shone on him. His messy hair and tired face seemed to remind him to be on his toes at all times, not to leave the monsters with room to kill him.

The long night was accompanied only by the sound of water droplets, which pushed him into sleep like a lullaby, and just as he was drowsy, the sound of a terrible iron pipe was heard in the depths of the corridor to his right.

Chen Ji seemed to have a bombshell in his head, which made his whole body sober up, and a thin man appeared on his forehead. Because he knows what this sound is coming from! Then he gently stepped on the fire and began to shake several people around him.

The people who woke up were very annoyed, and they just wanted to shout but were covered by the people who woke up before, and they were about to be angry when they heard this terrible voice, and their faces suddenly turned pale, and the whole person shuddered.

It's a familiar voice to them! It's a mutant cat, they encountered a mutant cat a few days ago, and in order to kill the mutant cat, they fought to the death of five people before finally killing it! Now there are only seven of them left, and the injuries on their bodies have not yet healed, if they force themselves against this mutant cat, I don't know what the outcome will be.

However, instead of fighting, they held their breath and leaned against the wall, trying not to make a sound.

They chose to escape! They were afraid, they were afraid that they would die at the hands of the mutant cat. "Squeak~squeak~" As the sound approached, a thin man even appeared on everyone's foreheads, covering their mouths with both hands, for fear of making a sound.

Chen Ji, who was sitting in the deepest part, saw a feline stronger than a tiger walking slowly under the faint reflection of water light, and this animal was a mutant cat.

Everyone held their breath, staring at the dark shadow by the wall.

The mutant cat slowly stopped in front of the entrance of the cave, and under the faint fluorescence, it could be seen that the body of the mutant cat was close to two meters, and the body was covered with black fluff, and its two furry front paws revealed their claws that emitted silver light to cut more than a foot of cracks on the ground, and it slowly turned its head to look at the depths of the tunnel, and the corners of its mouth grinned, revealing its white fangs, as if laughing!

"Oops, it's still been discovered!" Everyone was shocked.

Before they could react, "Roar~" The mutant cat suddenly rushed into the cave with a sudden force.

"Ahh The mutant cat enters the cave like a tiger and begins to slaughter like a flock of sheep!

Raising two furry claws, he cut the bodies of the outermost two people in the corridor, and the blood-stained large and small intestines attached to the claws were dragged out.

In the blink of an eye, two people had already died under its claws.

"Fire Charge~!" A sphere of flames lit up in the cavern and bombarded the mutant cat's abdomen, but it didn't seem to do any damage, just burned the fluff.

The few who survived were terrified! Afraid that they would die here, they used their skills to fight against the mutant cats.

"Boom!" Under the light of the flame charge, Chen Ji saw that the mutant cat's eyes were the same as those of a human! The cold hairs on his back stood up, and his hands were leaning against the wall, he wanted to escape, but found that there was no way back! I could only watch the mutant cat advance towards his side.

"Piercing!" A middle-aged man sitting next to Chen Ji let out a loud shout, and his palms slapped on the ground with a turquoise light.

The cement on the ground seemed to have been hit by a huge impact on the ground and broke directly, and the steel bars were erected, like arrows off the string, flashing with cold light, and went straight to the mutant cat.

In this cave, the mutant cat is in a dilemma, waving its front paws to block most of the steel bars, and finally the two front paws are pierced by several steel bars, and large patches of blood spurt out of its wounds and spill on the ground.

"Freeze!" A trace of hoarfrost rose in the mutant cat's hair, and the temperature in the corridor instantly dropped by a few degrees, and the water on the ground began to freeze.

Just when everyone thought that the mutant cat had been hit, the mutation suddenly appeared, and the mutant cat roared angrily, and its claws were like sharp blades cutting the steel bars of its front paws, and it suddenly jumped in.

In the blink of an eye, two more people died in the claws of the mutant cat, and at this time, there were three survivors plus Chen Ji.

"Get me out!" Chen Ji's eyes dilated, and he only felt a hot pain in the back of his body, and then his whole body was thrown up.

The mutant cat waved his front paws and slapped Chen Ji on the wall on the side, fortunately, he was not hit by the claws, he only broke two or three ribs at this time, he lay on the ground, and a sharp pain in his chest made him want to scream, but he couldn't help but look at the man who had just pushed himself out with a hideous face, and in his heart he greeted the eighteen generations of the man's ancestors.

"Brute, Lao Tzu tears you apart." The two men roared in unison, and unleashed their most powerful skills towards the mutant cat.

The mutant cat couldn't dodge it in such a small space, and it opened its bloody mouth, baring its white fangs, and waved its claws at the two inside.

A red ball of light appeared in the air, suddenly enlarged and then suddenly gathered.

"Boom!" The powerful wave knocked Chen Ji away again, and this wave actually broke his left arm directly! Confused him.

You can see how powerful it is!

Consciousness gradually returned, Chen Ji's ears roared, as if a grenade had just exploded beside him, and when he endured the pain in his body and got up again, the two people were already dead, and the mutant cat's chest was even cracked with a huge opening, and fragments of blood and internal organs slowly flowed out, and it was already dying.

Chen Ji looked at the corpse on the ground with a little fear and surprise in his eyes, they were so powerful before, they actually died, and in the end, they survived as an ordinary person who had not been upgraded. It was only when he looked at the dying mutant cat that his eyes flashed with joy.

What is this! It's an experience! The mutant cat has already killed these people, and the experience of these people has been integrated into the body of the mutant cat, if you kill the mutant cat yourself, you can get a lot of experience points! Chen Ji pulled out a dagger that had been hidden in his shoes, dragged his tired body to the mutant cat.

The mutant cat saw that he wanted to resist but thought that he had no strength, so he could only watch with a cold gaze as Chen Ji stabbed it with a dagger into its neck.

A flash of white light! The sharp dagger pierced the mutant cat's dense skin and finally pierced into the mutant cat's neck, and blood spurted wildly, hot blood spilled on his face. But he didn't feel sick, he only felt joy.

He closed his eyes and felt the familiar panel change!
