So far, no one knows how the first corpse variant appeared, 6 years ago, mutant creatures suddenly appeared in major cities, and began to spread wildly.

Infected humans are emaciated at a visible rate, leaving them with only skin and bones, but their skin is incredibly tough and powerful. Without exception, they all have sharp teeth and nails, and their broken wounds are covered in viral mucus.

Some have mutated, or they have become huge, or they have grown three or even four hands, or they have grown bat-like wings, and so on.

In short, none of these infected people can be called human anymore.

People and animals that have been bitten or scratched by these variants, or whose blood has been contaminated with corpse fluids, may quickly turn into corpse monsters in just a few tens of seconds, and die without stiffening. It is also possible that there was nothing abnormal at that time, and it became a potential source of infection, and it broke out after a certain period of time, and the second type is the most terrifying, and many people are cheated by relatives and friends in this way.

It is said that most mutants are capable of maintaining a simple and special intelligence, they do not kill each other, can identify and let go of infection carriers, and attack wildly when they see normal humans.

Because mutant organisms are extremely contagious, ordinary soldiers come into contact with them on the battlefield, and some of them become infected and defect after dozens of seconds. It is possible to incubate for two or three days before erupting, bringing disaster to the entire barracks.

After suffering a great loss, the human army retreated to an island separated by the ocean to enclose land to protect itself. It was an unprecedented retreat, and unfortunately only 500 million people survived.

Alloy Warriors are a special army that only appeared in the third year of the apocalypse, and scientists have developed an all-metal exoskeleton with excellent protection, which not only gives humans the ability to fight mutants in close proximity, but also allows individual soldiers to carry more weapons and ammunition, giving full play to their powerful firepower advantage.

"The world can be destroyed, but humanity will never perish, join the Alloy Warriors and take back our homeland!" Not long after this slogan appeared, Nantes and Lao Ma became excellent members of it.

Right now, these two best alloy warriors, the chosen ones who shoulder the hopes of 500 million human beings, are squatting on the top of the 15th floor of a residential building like an old farmer, pinching the butt of a cigarette and smoking.

Lao Ma sat on the ground leaning on a dilapidated solar water heater, holding a small notebook and drawing something, and chanting words in his mouth with a cigarette: "The intelligence says that the opposite building is 259.7 meters high, with more than 500 rooms, and it is cleaned up layer by layer, and they have to be allowed to escape in a fixed direction......

Nantes shifted her ass and leaned over to take a look, scurrying away.

On that piece of paper was an extremely complex sketch and formula, and the calculation steps were densely packed......

His voice came from behind him: "Little pumpkin, calculate this problem, it is the battle data we need to attack the building......"

"Teacher, spare my life, I have thought of a good way." He quickly diverted the topic and handed a look of help to the "manager".

"I'm sorry Captain Little Pumpkin, the 'Little Pumpkin' brought by others is not powerful enough to blow up such a big building." The white face was full of evil smiles: "But if I cooperate with the mandrill, I can burn it." ”

"Mandrill" shook his head: "I remember that there was an order from above to preserve the main structure of the city buildings as much as possible. I can't control it, this fire might just be able to burn the sky. ”

"Fuck the order of the superiors, the internal structure of this building is complicated, there are only 6 people on our side, fart, you are injured and dead, I have to climb the building to rescue, 48 floors, I'm going to die!" It was their medical officer, Zhang Yang, who said this.

Zhang Yangren gave the nickname "Runaway Youth", and this nickname does not mean that there is a problem with his life style, nor does it come from the glorious deeds that he has seen the plump body of the "second master" and has not been beaten, but the profile of his personal social account is: "Disappointed by the times, he has become a romantic figure through the ages."

It is said that this guy was determined to study medicine at a very young age, and his family clapped their hands: "It's good to study medicine, it's very profitable to study medicine!" ”

He asked with a serious face: "Didn't the doctor save people?" ”

As a result, such a peerless genius with noble innocent thoughts broke out in an apocalyptic crisis before he finished his clinical major.

His graduation thesis is a "My Views on Sexual Reproduction between Mutants" (the last three words of the title "I See" are emphasized), the paper was a sensation, and many people who eat melons thought that he had seen indescribable live pictures, and they spent money to check the papers, but they didn't expect to read tens of thousands of words, and only found some research speculations about DNA or something.

I don't know if my superiors have read this paper, but it is said that the leadership of the Joint Commission unanimously agreed that his research was of great importance to the survival of mankind, and decided to let him go to the front line to do a good research, but unfortunately ended up in the "Pest", a team known for its laziness.

"The stumbling brother is right, the so-called generals will not be subject to foreign military orders, little pumpkin, as the captain, you must be responsible and dare to disobey!" Liu Lang, who was the commando, spoke righteously and passionately, and he almost cried Nantes.

This guy is not greedy for life and afraid of death, he is a human being who lives up to his name, and when he fights, he is called a wave, and he always rushes forward.

"Misstep" was afraid that he would have an accident and make trouble for himself, so he cleaned him up fiercely when he was injured in a training session, and then made a promise of "giving birth to boys and girls at will", so Liu Lang became his exclusive follower, as if he had reached the level of "husband and wife".

The old horse tore off the calculation paper on the small notebook, crumpled it into a ball and smashed it on the mask of Nantes' helmet: "I think it's okay, light the fire to save time and trouble, give an order!" ”

The "manager" took out a drone from his back: "This is really a piece of cake for me, give the order, my captain!" ”

Liu Lang directly pressed Nantes's hand: "Give the order, captain!" ”

Nantes suddenly felt that this scene was very familiar, as if such a scene had appeared in many old movies.

He felt that he should be like the guerrilla leader in the film, knock on the cigarette pot and say: "Comrades, you can't fight!" ”

But when he dropped his cigarette butt and was about to convince them, the voice of "Second Master" came from the team channel: "What's the matter, hurry up and light the fire, or not a man?!" ”

The others suddenly agreed: "Gotcha, go!" ”

Nantes: "Hmm??? ”

He didn't give this order, but who would believe it?

"Mandrill" removed the small incendiary bomb launch module on the alloy armor, and buckled it to the card slot of the drone very lightly, and there were words in his mouth: "It's still the second master domineering, a real man, a pure master!" ”

There was silence on the team's channel......

I don't know why, as soon as the straight man speaks, the oxygen in the air is a little thin.

Seeing the drone flying into the sky, the old horse, who was born as a math teacher, had already calculated the best attack method, he handed the note to the "manager", but the other party did not answer: "You read it, where to fight!" ”

Nantes wanted to take two steps back and secretly record the picture of the two people in embarrassment, so as to leave a piece of evidence for himself in the future military court, but he didn't expect that the two people behind him had already surrounded him tightly: "The captain is wise!" "Captain great!" "Captain...... It's handsome! ”

The fire started from the top floor, the city fell for 6 years, the building's automatic fire protection facilities have failed, but the hotel has a lot of combustibles, and the incendiary bomb has turned into a blazing oversized torch in a few seconds.

Nantes saw all sorts of strange mutants lying on the edge of the window and banging on the glass, fearing that they would not be intelligent enough to do something stupid about jumping down from more than 40 floors, so she took the lead in raising her gun and shooting at the window.

The drone dropped an incendiary bomb every two or three floors from top to bottom, and the fire grew bigger and bigger, and the 20th floor up was in flames.

More and more black-and-gray figures ran down from the upper floors, and when they reached the low floors, they simply broke out of the windows and ran towards Zhongshan Square in front.

The old horse stopped the fire, turned around triumphantly, and waved the small note in his hand: "There are two advantages to starting to burn from the top layer first, the first is to drive the corpse variants above to flee downward, after all, we want to live." The second is that the fire spreads slowly downwards and is easy to control. It's called science! ”

In just a few minutes, the former high school math teacher even formulated a fire extinguishing plan: "Don't look at the fact that there are only 7 of us, but we can extinguish the fire in this 259.7-meter-high building in an instant, believe it or not?" ”

"Believe it, believe it......" Looking at the huge barrel of the gun that was smoking at everyone, Nantes nodded hurriedly: "Whether others believe it or not, I believe it anyway!" ”

Only then did he smile and put away the huge Gatling Vulcan cannon on his waist.

"It's worthy of being a rigorous math teacher, and at this time you can still say the decimal point so perfectly, naturally without any sense of abruptness......" "Mandrill" took a "perfect" sycophant in hindsight.
