Dongdongdongdongdong.

The sound of the running of the large army seemed particularly heavy in the underground corridor, making people's eardrums tremble.

From time to time, there were several desperate screams and curses, but they were soon drowned in a whine.

"Help! Save us!"

The survivors in the subway tunnel rushed up the stairs first and shouted to the four people standing against the light at the top of their lungs.

The primary zombies reacted very slowly, their bodies were stiff and slow, but they were instinctively following the smell of strangers and chasing them behind.

A survivor fell while running, and the zombie group immediately rushed up and ate all of him in a few seconds. Then he dragged Canpo's body to become a member of the zombie army.

The survivors who escaped were even more panicked, and their useless clothes and luggage were still behind them.

There are college students who push their girlfriend into the zombie group to buy time, there are middle-aged women who try to protect their husbands' bodies after being bitten by zombies, and there are also middle-aged women who are trapped in the zombies and try to push the young child up the stairs with their arms stretching out their arms

young father.

Human nature is fully displayed in this cold and dark world.

Lu Sheng tightly grasped the handle of the knife, and the arc instantly covered the entire blade body.

The remaining survivors rushed out of the subway entrance immediately, and the remaining zombies were staggering and stagnant, and they all turned their eyes to Lu Sheng and the others.

"Aowuaowuaowuaowu."

The instinct of hunger and the delicious and seductive smell of living people tempted the zombies to rush towards Lu Sheng and the other four.

In the tense atmosphere, Xiao Yu's lantern fruit emits a more dazzling light.

The gray skin, the faintly beating blue blood vessels, and the undecayed zombies look much cleaner and more beautiful than the previous life.

clang!

The Tang sword was unsheathed, and the sound was like breaking ice.

The cold light entwined the arc and splattered a stinking blood mist.

The zombies rushing in the front row fell down, and their bodies were immediately gnawed by the zombies rushing up in the back row...

The zombies have no pain and no ability to think. Even if they only have half of their bodies, they will lie on the ground and squirm towards the breath of the living.

Lu Sheng's Tang sword was like a jade dragon entering the sea, tearing a bloody path among the endless corpses.

Xu Yi's nail gun was in his soul, and Xiao Yu and Sun Tiantian also tried their best to wield their weapons, killing the zombie who had been lucky enough to bypass the sword light.

"There are more and more zombies, and I can't kill them at all." Xiao Yu and Sun Tiantian were already sweating profusely.

Although the speed and power of the zombies that had just become transformed were all fighting against the five scumbags, they could not resist the number of people.

Although the four of them cut melons and vegetables, sparks and lightning were all the way, cutting zombies was also a physical job. After cutting one and rushing up, they would not be able to keep up with their physical strength in the future.

There were already mountains of corpses and blood in the subway corridor, but there were still a continuous stream of zombies rushing up from the depths.

"You three retreat to the exit first." Xu Yi put his glasses in his shirt pocket and fired five shots in a row, sniffing the headshots of several zombies closest to Lu Sheng.

Lu Sheng and Sun Tiantian and Xiao Yu looked at each other, not knowing what Xu Yi was going to do.

"hurry up."

Sweat wet Xu Yimo's short hair, perhaps because of taking off his glasses. In addition to his usual nobleness and elegance, he also added a bit of evil murderous intent and tension to his whole body.

Lu Sheng and Sun Tiantian and Xiao Yu quickly retreated to the subway entrance, and the staggering zombies rushed towards Xu Yi.

Xu Yi jumped into the small pavilion next to the ticket gate and led all the zombies to a narrow location.

The junior zombies do not have the ability to climb and jump, so they can only gather next to the pavilion and stretch out their hands to grab Xu Yi.

Seeing that almost all the zombies gathered together, Xu Yi took out a special sealing bottle of about 500ml.

Xu Yi pulled open the button on the top of the shirt and threw the bottle at the corpse.

The bottle exploded in the zombies, and the liquid in the bottle was splashing everywhere. The bloody wounds of the zombies touched the liquid and immediately suffered a violent chemical reaction.

The wounds burned quickly, and the zombies were unaware of it. The flames spread wildly among the zombies with a prairie fire.

The air was filled with the smell of charcoal fire with fat burning, and the thick and choking smoke blurred the sight of the primary zombies. They pushed and trampled on each other like headless flies.

Xu Yi took advantage of the chaos and jumped down, stepping on the heads of several unlucky zombies and protruding out of the crowd.

Behind him, as the fire spread, more zombies were swept into the sea of ​​fire. The flames licked the zombies' skin, clothes and hair, and the sound of flesh explosions kept coming from the restless corpse group.

Xu Yi walked out of the subway entrance calmly with his back to the fire.

Behind him, the fire was rising, and the restless corpses gradually disappeared in the flames, leaving only the burning black charcoal.

...

The system prompt for obtaining new items rang hundreds of times in Lu Sheng's head, which made her ears numb, and even the sound of Xiao Yu and Sun Tiantian talking could not be heard.

In the most conspicuous position in the space, newly acquired items piled up into hills and a large number of shiny crystal cores.

“6!”

Sun Tiantian and Xiao Yu gave Xu Yi thumbs up and asked curiously, "What is in the bottle? You can handle so many zombies in one bottle."

"Nitroic acid." Xu Yi put on the half-framed glasses again and reached out to dust off the floating ash on his cuffs. "The strong oxidation of nitric acid will produce a lot of calories when it comes to contact with zombie fat."

"I was the first to object to Teacher Xu's abandonment of chemistry and practice medicine. If I had known such a chemistry teacher, would I have been dragging my feet on the college entrance examination?" Xiao Yu smiled and joked.

“6!”

Lu Sheng couldn't help but hit the 6 to the public screen.

Learn mathematics, physics and chemistry well and travel all over the world!

The four of them entered the subway station again, and the underground corridor was filled with a pungent smell of burnt. Zombies near the ticket counter were piled up into mountains, and occasionally a few of them fell to a few meters away.

"The crystal nucleus is in the zombie's brain. Be careful when digging. Some crystal nucleus may be the size of rice grains."

After Lu Sheng explained the key points of digging crystal cores to Xu Yisun Tiantian and Xiao Yu, the four of them began to dig crystal cores in different areas.

It only takes ten minutes to kill zombies, but it takes more than half an hour to dig crystal cores. Not all zombies have crystal cores in their heads, it all depends on luck.

There were too many corpses, and the hands of the four people were sore after being dug.

Sun Tiantian and Xiao Yu dig the most hard, holding a small dagger and digging, making them look like two emotionally ill-taught brain-drawing tools.

"It's all here."

Xiao Yu panted and handed a bag of crystal cores to Lu Sheng.

After a rough glance, there were hundreds of crystal cores, including high-level quality.
