May 20, 2015, around 7 o'clock in the morning.

It was supposed to be the beginning of an ordinary day, as usual, and the American city was about to start bustling again after a night of silence, but, suddenly, the world changed, and it became so abrupt that everyone was caught off guard: streets, residential areas, shopping centers, administrative buildings, military bases, scientific research centers, and even ...... The White House, the whole of America, everywhere there are people, is in a huge mess, and this chaos is spreading unstoppable......

Don Ji was woken up from his old apartment bed, and the sound of a car crashing could be heard outside the window, as well as the high-decibel screams of women, and strange roars.

Tang Ji smelled a faint smell of blood, this smell naturally could not have come from the window, closed the window, Tang Ji did not have such a keen sense of smell, the smell came from the building where his apartment was located.

Bang bang bang...... The violent slamming of the door caused the startled Don Ji to turn his attention to the direction of the door, and vaguely, he also heard a strange roar coming from the corridor outside the door.

"Anyone? Please open the door, open the door, they are coming, help me! After the door was slammed, there was a panicked woman's cry, Don Guy knew the owner of this voice, he could hear it, it was Maniela who lived next door to him, Don Guy didn't know her very well, but he had lived here for a long time and knew her, Maniela was a twenty-two-year-old girl, and shared a house next door with a girl named Bellucci.

"What's wrong with her?" The thought flashed through Don Ji's mind, and he didn't have the heart to think about it, since someone smashed the door and shouted for help, he had to go and see it, because he didn't know what was going on.

Don Guy, who was wearing boxers, quickly jumped out of bed and casually picked up the baseball bat that was placed next to the bed.

"What's wrong, Maniela?" Tang Ji walked to the door and asked calmly and quickly, only Maneela's panicked face could be seen in the door mirror, as if something extremely frightening had happened, the old apartment was not well soundproofed, so close to the door, the strange roar outside was more obvious, and there were some scalp-numbing chewing sounds, some like the sound of dogs biting raw meat, and the bloody atmosphere became more and more intense.

"Please, hurry up, ah!" Maniela let out a final scream, and Tanji could only see a bloody hand grabbing Maneela's shoulders and pulling her out of the mirror's range.

Tang Ji no longer hesitated, slammed open the door and rushed out, the sight that swept into his eyes completely shocked him, on the right side of the corridor, seven or eight meters away, in front of Manilla's door, a middle-aged man with nothing on his body and a little fat pressed a woman who was also undressed to the ground, and the two of them were covered with blood, all of which were the blood in the woman's body, because the middle-aged man was leaning down and biting the woman, eating her flesh, the woman's stomach had been scratched open, the flesh was blurred, and the intestines flowed all over the ground, Blood flowed everywhere.

This woman, Don Quixy, also knew, was the same lady Bellucci who shared a room with Maniella, whose throat had been bitten off and seemed to be dead.

Depending on the situation, the man who was eating her should have been the guest they left for the night yesterday.

And just four or five meters away on the left side of the corridor, the same naked man was pressing Maniela to the ground, trying to lower his head and bite Maniela, who was also undressed, and let out a strange roar in his mouth, Maniela supported the other party's shoulders with both arms, screaming and struggling.

Tang Ji was only stunned for a moment, and at this time, he didn't allow him to think too much, so he quickly ran to Maniera's side with a baseball bat, and hit the head of the man who was about to bite with his blow, knocking him to the ground, and pulling Maniela up with a single hand.

"Click!" The man was also covered in blood, it should be Bellucci's blood, he was hit the head by the bat and didn't seem to be harmed, rolled out, and immediately staggered to his feet again, and roared at Don Quixy, who noticed that his eyes had completely turned blood red for some reason.

The man began to stagger towards Tang Ji, his face was hideous and he kept roaring, his movements were not fast but definitely not slow, at least the speed of a normal person walking, and he looked a little awkward, as if his muscles were stiff.

On the other side, the middle-aged man who was eating Bellucci stood up, noticed Tang Ji, and also roared towards Tang Ji.

"What's going on?" Tang Ji was also a little nervous, and pulled Maniela back to his room, which he had never encountered before.

"They're crazy, they're all crazy...... They ate Bellucci......" Maniela cried out, clutching Donji's arm.

At this moment, in this corridor with a total of seven doors, two doors opened at the same time, one door was knocked open because there was no security door, and two soulless people like walking corpses walked out of it, both with blood-red eyes, Zhang Ce knew, it was a young couple living in this building, they also had a lovely daughter, but they did not follow out, from the appearance of the couple covered in blood, Tang Ji had already guessed what was happening.

The other door that opened at the same time was opened, and rushed out a man who was clutching his neck, his fingers were still spurting blood, as if he had been bitten on the neck and destroyed the artery, the man had just rushed out and fell, crying in panic, as if he was about to collapse, and another woman came out of the room, grabbed the man's ankle, and dragged him back to the room with ease......

This was the last sight Don Guy saw, and the next moment he had already taken Maniela back to his room, and closed the door deadly.

Bang bang bang...... Bang bang bang......

The irregular sound of banging on the door, the force was very great, the door was trembling, Tang Ji was already in a cold sweat on his forehead, swallowed his saliva and looked out through the door mirror, two men with blood-red eyes were scratching and banging on the door, with their big mouths open and their expressions were hideous, Tang Ji could even see the unswallowed minced meat in their mouths.

Tang Ji looked at the door, slowly stepped back, and at the same time turned his head to the crying Manira and made a "shhh" gesture, it can be determined that these people are crazy for some reason, and the madness is not light, since they are crazy, then it is likely that they unconsciously rely on instinct to distinguish things, if there is no sound guidance, they should soon stop banging on the door, Tang Ji is a medical student, even if it is not his major, he knows a little bit.

Maniela immediately covered her mouth and collapsed to the ground looking in the direction of the door, shaking her head and shedding tears.

The knocking on the door died down after two minutes, and the two "madmen" seemed to be attracted to other normal people and left the door of Don Ji's apartment, where he heard screams outside.

"They're gone,......" Tang Ji breathed a sigh of relief, and said in a small voice, a very bad premonition grew stronger and stronger in his heart, and he walked to the window with a light step, and opened the curtain to look out, and the street was outside.

The street has become chaotic, full of the kind of stiff "madmen", the cars have basically been crashed, some cars are on fire and emitting billowing smoke, many normal people are running frantically, trying to avoid those "madmen", but the "madmen" are too many, the number is far more than normal people, although the speed is not as fast as normal people, but only a very small part of the people under the siege escaped from Tang Ji's sight, and the rest were caught by the "madmen", surrounded and eaten!

"They're crazy, they ate Bellucci...... Oh, God...... They killed her......" Maniela cried quietly.

"It's not that they're crazy, it's that most of them are crazy, come and see." Tang Ji stood by the window and whispered.

Maniela looked up at Don Guy and stopped crying, looking a little disbelieving, and Don Ji beckoned to her again, before she got up and walked to the window and looked out.

"Oh, God......" Maniela covered her face and crouched on the ground.

"Probably a chemical or biological weapon." Tang Ji whispered, put his hand on the curtain, and pulled the window tightly. When this happens, Don Ji first thinks of terrorist organizations, and then Russia.

What he doesn't know now is that things are far worse than he thought.

Tang Ji turned around and walked to the window, turned on the TV and quickly turned the volume to the lowest, first of all, CBS TV, this time should be broadcasting the morning news, live broadcast, the picture on the TV is indeed live, and the live broadcast is also the scene in the live broadcast room, but ...... The two presenters were gone, the table was messy, press releases were scattered, and there was a large pool of blood on the wall behind the desk.

CBS TV station also had an accident, Tang Ji began to quickly change the channel, and found that all the programs that broadcast the news live are either playing messy live broadcast room pictures, or they are a colorful stripe, only part of the recorded morning program is playing normally, but that is only a part, more colorful stripes, or even no signal.

"It's all wrong...... It won't be such a coincidence...... Unless ......" Tang Ji glanced at the curtains, suddenly turned over and climbed into bed, took out his mobile phone from under the bedside pillow, clicked on the address book and slid down, found the phone named "Doctor Mine", and dialed it.

"Quick...... Fast...... Answering the phone......" Tang Ji took a deep breath and whispered in his mouth.

A minute later, Don Ji put down his phone, and the call went unanswered.

Leaning on the bed, Don Ji was silent for a while, then took out the phone again and dialed two numbers, which belonged to his parents, all of which were answered.

There was an eerie silence in the room.

Maniela sat naked on the floor by the window, her arms folded and her legs folded, her head hanging down at the ground, her lips trembling as if she was muttering something, but she didn't make a sound.

Donji was lying on the bed, looking at the ceiling, his eyes blinking, not knowing what he was thinking, he needed to calm himself down.

For half an hour, the chaos outside the room was a little smaller, everyone who could run ran away, those who couldn't run died, and all that was left was the roars of the "madmen".

"What just happened? What happened? Don Guy came back to his senses, tilted his head to look at Maniela, and asked suddenly.

Maniela raised her head, her mood was much better, she looked at Tang Ji, lowered her head again, and whispered: "This morning, I got up to take a shower, and when I was just halfway through the shower, I suddenly heard Bellucci's scream, I rushed out of the bathroom, and saw the two guests biting Manila, I panicked and was a little angry, I picked up something casually, and I didn't pay attention, so I smashed it at the two people, pulled Bellucci and ran out, and those two people chased it out and caught up with Bellucci behind...... And then...... And then ......" Maniela was a little agitated and seemed to cry.

"Okay, I got it." Tang Ji interrupted her, and he basically saw the rest of the situation.

Don Ji got out of bed and glanced at Manilla, as a man, it was just a subconscious move to see a woman without clothes to glance, and if a woman saw a naked man, it would also behave like this, it didn't mean anything.

Maniela is a beautiful woman, with a very surname on her lips, younger than Don Guy, but very mature, exuding an aura of temptation, which may have something to do with her profession, especially the pair of plump and big on her chest, I don't know if it's long, Don Guy just glanced at it, then walked to the closet, took out a big shirt and shorts and threw it to Manilla.

"Get dressed!"

Tang Ji is not a decent gentleman, and he has not spent money, but if he was still thinking about that kind of thing at this time, then he must have been kicked in the head by a donkey.

After throwing Maniela's clothes, Don Ji put on jeans and a t-shirt himself, and put a leather jacket on the outside, then leaned over and pulled out a small black suitcase from under the bed, opened it and took out a silver-gray pistol from inside, this is a 9mm Beretta 92F pistol, which is commonly known as the M9 pistol, in the United States, where guns are flooded, this is the most common pistol, Don Ji because of his underground work involved in the black, just in case he bought this gun, a year, he has not officially used it, However, he went to the shooting range to practice pistols, and it was no problem to use such pistols.

In addition to the pistol, there were two magazines and a box of ammunition in the suitcase, and the rest of the place was some brand new scalpels and medical blades, as well as other hemostats, gauze, disinfectants, needles and threads and other surgical equipment, all brand new.

After checking the magazine inside the pistol to make sure there was nothing wrong, Don Ji pinned the gun to his waist, locked the suitcase, and stuffed it back under the bed.

Maniela, who was already dressed, stood by the window and brushed her hair, looked at Don Quixy, and wanted to look at the gun on his waist, her eyes were a little inexplicable.
