Jiang Sen has already deeply studied the map of the city, and the layout of the city is still very regular, and in order to survive in this city, Jiang Sen has deeply engraved the map of the city into his mind.

Before dawn, he changed into an M16 rifle, carried the HK416 assault rifle that accompanied his rebirth, and left the small building in the early hours of the morning with a backpack containing magazines, food and water.

He walked like a ghost blended into the darkness, walking through the empty city.

"Poof!" The light released from the muzzle of the pistol gunpowder was instantly swallowed up by the night, and the bullet flew out through the muzzle muffler, detonating a zombie tied to a seat belt in the cab of an Audi.

Jiang Sen pulled the body out of the car, started the engine, and got on the elevated highway around the city.

At the time of the disaster, the viaduct around the city was blocked to facilitate the dispatch of rescue personnel, so there was only an occasional entrance and exit of the entire viaduct with a police car with an open door.

Although the "Audi Lamp Factory" has always been "buying the lights and sending them to Audi", Jiang Sen did not turn on the lights. The black Audi car blends completely into the dead silence of the city.

The elevated highway spreads endlessly in the pitch-black reinforced concrete buildings, and the dark night of the city without electricity seems particularly unknown.

The cab window glass had been destroyed, and the summer evening breeze was still sweltering, even though it had avoided the sun overnight, and the breeze blew into the car with a faint stench.

The bodies of the dead in the city are decomposing, and the gnawed remains are drying out. Flies and mosquitoes swirled and multiplied over the dead bodies, and rats and cockroaches gathered next to the rotten bones. They may have sensed that the world was changing, but they hadn't changed their rancid habits. It doesn't really make a difference between the living and the dead.

In the midst of the great apocalyptic hardships and fears, the dark night would bring Jiang Sen an inexplicable sense of security, and he drove his car back and forth in the city.

I don't know how long it took, the morning sun rose in the east, Jiang Sen stopped the car on the elevated highway, and one person watched the side of the car and saw how the morning sun came out of the horizon. After that, he got into the car again and began to wander around, going in and out of the city, out of the city and into the city.

He doesn't seem to have a fixed goal, just walks back and forth through the streets. The gauge hand showed that only a third of the fuel in the tank was left, but he didn't care, still maintaining a fixed speed.

There are no traffic lights, no one rebukes the wrong direction, it seems to be just his city.

Although most of the zombies in the city are gathered together, there are still a few scattered in some corners, attracted by the sound of car engines, and they are excitedly running towards the Audi, howling and chasing. There were also a few very unlucky guys who were knocked off the spot, rolled on the ground a few times, and got up again like an immortal superman.

Finally, the Audi stopped at an intersection, and the pop-up glance at the square next to the intersection was then restarted, entering the underground parking lot of a nearby office building.

The Audi came to a slow halt in the underground parking lot. Jiang Sen walked down with his backpack and weapons, looked around smartly, and made sure that there were only zombies behind him, and there were no snoopers, and then he stepped forward, without making a sound, holding a gun, and vigilantly opened the door of the stairwell, and the black in the stairwell was instantly driven away by the strong flashlight under the gun, probably because of the outbreak of the disaster, the people in the building went to squeeze the elevator, so there was not a single zombie in the entire stairwell.

Jiang Sen entered the stairwell, turned off the flashlight under the gun, and landed on the floor one by one like a ghost.

He didn't climb too high, "Bang bang! On the third floor, he could see knocking on the doors of the rooms in the square next to the crossroads, and after finding a room that didn't seem to be a zombie, he used the tools he had prepared in advance to pry open an unresponsive room and dodge in.

It's an office with a small size. Through the window, you can see the wide road and the empty square.

The lock cylinder was not damaged, the door of the room was tightly locked, and after confirming that he could leave the room through the window along the drain pipe, Jiang Sen put down his backpack and gun, took out the packed lunch box from the backpack, and ate it slowly.

At the end of the road in the distance, a zombie with a dazed expression slowly walked over. It walked slowly, looking around for edible creatures.

It wasn't alone—more than ten meters behind it, it was followed by five or six companions in ragged clothes and ugly faces. Viewed from the air, they resemble an irregular arrowhead, guiding a dense group of corpses that staggered dozens of meters away through the messy piles of cars on the road.

This is just one of the countless huge hordes of corpses in this city. They were originally gathered together by a loud noise, but now they move aimlessly, and no one knows why they are here. Can't tell what exactly they're attracted to? Various styles of shoes trampled on the green belt, and abandoned vehicles scattered on the road were flooded with corpses. Mosquitoes, which like pus and rotten flesh, flutter over the corpses like a black wind.

The road after the corpses passed, like a flock of sheep walking by, leaving behind filthy excrement along the way.

Jiang Sen sat by the window, looking indifferently through the binoculars at the dense march of corpses on the street below. He didn't raise his gun, he didn't show his killing intent, and he wasn't ready to take any action, he just observed.

The biggest advantage of being reborn is knowing the future in advance.

There are signs that some interest groups may have anticipated this worldwide outbreak. There was no rescue, and there was no broadcast to the population.

Interest groups fled the cities to establish new settlements in the wilderness. After order was gone, they recreated it and became several powerful groups, and Jiang Sen was the leader of a special operations team in the American Western Bloc before he was reborn.

Since then, the changes and development of human society have been very familiar to Jiang Sen. However, by chance, he came across a file, a top-secret document from the North American Central Group, and Jiang Sen was tasked with bringing it back from a base in the city.

Half of his squad sacrificed for this file, he wasn't a soldier, he was just hired, so he opened this file, which was a relevant record about the study of genetic potions. In the "Remarks" column of the document, the words "Reagent Zero is missing" are written.

Genetic medicine is incomparably precious in the future, Jiang Sen was shocked at the time, when the disaster broke out, all mankind was looking for the first "patient zero" infected with the zombie virus, and then used it to create a vaccine, so what is this zero reagent that is defined as a genetic medicine?

According to different effects, genetic drugs are divided into immune, strengthening, cell repair and other types.

The records are entered very carefully, and there is no possibility of adulterating irrelevant information in them. In particular, for columns such as "Remarks", which must be specifically explained, the text of the record must be reliable and detailed.

Hidden in this simple message are two kinds of interrelated content.

1. The detailed classification of gene drugs, as well as a variety of research data, should be the research results of the research institute on the zero reagent. The documentation does not mention the specific efficacy of Reagent Zero. Jiang Sen guessed that the use effect of Reagent Zero should far exceed that of genetic medicine. Even, it is a synthesis of different kinds of genetic drugs.

2. Long before the outbreak of the virus, the research institute had obtained the No. 0 reagent, but it suddenly encountered an accident and did not conduct systematic research on the drug. It is likely that they have only obtained a partial range of relevant data, and the information and recipes are not comprehensive. Because, at the bottom of the "Lost" remarks column, there is also a date ———— "August 2, 2120".

That is, today, since Jiang Sen has been reborn, he is going to get this disappeared "No. 0 reagent".
