It was summer, the sun was shining brightly on the dead city, and when I opened the window, a hot breath rushed in unceremoniously, making the air-conditioned room stuffy.

"Are we really going to wear so thick to go out? In this way, it is estimated that we were not bitten to death by zombies, but also suffocated to death. The big black bear opened the window, and the hot air coming in from outside made him sweat like a dumpling.

"I think it's better to forget it. We've all been strengthened now, so we probably won't be infected. Lu Yu'an was also sweating profusely, and he felt a lot heavier when he was wearing too thick.

"You can't kill the enemy at all, your body is too bulky. And once you do strenuous exercise, I'm afraid you won't be killed by heat. Yang Jian also admitted defeat, he really couldn't stand it.

"It's a strange weather, the temperature is 35 degrees." The psychiatrist didn't wear several clothes on his body like them, and he wasn't stupid, how could he be so hot and still wear so much.

"Master, even if you are strengthened, you will still be infected by zombies. Speaking of which, I'm going to give you a science popularization about the reasons for the birth of zombies. Alice said as she pulled out a teacher's whip out of nowhere, projecting a blackboard behind her.

It is not a virus that causes the mutation of zombies around the world, but the evolutionary particles emitted by this world.

As we all know, the evolution of both organisms and genes takes a long time to undergo. But this evolutionary particle emitted by the world accelerated this process, and the rapid biological evolution and genetic evolution caused the gene chain of a large number of life to be unable to withstand this evolution, and the gene collapsed and became zombies.

And the genes of all the survivors are stable, they can increase their strength by practicing the ancient exercises, and they can also grow through training. As long as you are willing to exercise, if you keep exercising, ordinary people in this world will have the opportunity to be as powerful as the zombies you saw last time, but their appearance will not change. Of course, humans can also devour zombies to evolve, but what evolves in this way is a half-human, half-corpse monster.

Becoming stronger through constant training and practice is the way of human evolution. And the evolution of zombies is to constantly devour, devouring the complete and stable gene chain of human beings to improve the broken gene chain on their own body.

By devouring human genes, they will become mutants after perfecting part of their gene chain, and when they completely perfect their gene chain, they will be complete body zombies.

Because the direction of refinement of the gene chain is different, the abilities of the variants are all different. According to the information displayed in the database, the mutant zombies in this world are basically divided into three evolutionary directions, Titans in terms of strength, ghosts in terms of agility, and ghosts in spirit.

Of course, this is not absolute, because only the slightest change in evolution can deviate thousands of miles.

If it is completely evolved by devouring people, there are about these three, but according to database statistics, the ratio of the number of human beings and the huge zombie base is 3:7. So it doesn't work to evolve by eating humans, so they can only devour each other. Although they are all broken gene chains, there is always a little bit of merit. Because it's a fusion of the gene chain that has broken down, no one knows what will evolve.

And the reason why humans also become zombies after being attacked by zombies is because the gene chain on his body is destroyed by zombies. As long as you are scratched and bitten, the virus or something on the zombie will enter the human body and destroy the stable gene chain in your body, causing the gene to collapse and become a zombie.

Of course, there are many ways to prevent this. For example, cut off the scratch and bite, preferably all of them. For example, biting the palm of your hand, cutting off your arm will be safe, because no one knows where the virus has spread. Alice grinned and said something terrifying, and she suddenly changed her mind.

"How can you use such a cruel method. You can buy an antidote from me for 5 kill points, and you can use it within half an hour of being bitten. Are you interested in buying a few to spare? ”

"Since there is an antidote, there is no need to wear such a thick one." When Yang Jian heard that there was an antidote, he took off all the clothes on his body, leaving only a vest.

"I have soap in my hand. Anyway, as soon as I threw my soap away, they fell aside, and then I swooped out. "The big black bear has long since taken off his clothes and is only a field vest, with a string of grenades around his waist, a submachine gun in his hand, two more behind him, and two rows of bullet chains on his body.

Yang Jian turned around when he heard the voice, and was startled by his dress, and circled around him a few times.

"Where did you get this outfit from, do you have so many killing points?"

"Bought with a loan. I didn't expect there to be a loan in this game. The big black bear looked up at the sky with a vicissitudes of life.

"Big Black Bear: I'm too hard."

"It's too miserable."

"It's too hardcore."

"Do you even need a loan for the game now?"

"The reality is to repay the mortgage, and the game still needs to be loaned."

"Don't say that I also took out a loan, the interest is high, I want to sue him for loan sharks, but it's a pity that he is the game currency loaned."

"I owe a lot of in-game currency to buy a piece of equipment."

A group of people were talking and there was a miserable atmosphere in the live broadcast room, and a large number of water friends found out that so many people had taken out loans in the game.

"Loans? What are you borrowing? Yang Jian was a little curious, he hadn't been playing for long, and he was a newcomer.

"World coin, the currency of the main city. Interest rate 10% per day. The thought of the high interest rate made his heart throb.

"World coins? Isn't it a federal gold coin? "Yang Jian originally chose the Terrans.

"This is the kind of world coin." The Great Black Bear pulls out a gold coin engraved with the World Tree.

"World Coins are common to the Overworld, but things like Federation Gold Coins and Elf Coins can only be used in their respective main cities. The ratio of the World Coin to the Main City currency is 1:10, but it is 1:1 to the kill point. I borrowed 100 world coins yesterday, and if I can't pay it back today, it's 11. ”

"It's miserable." Yang Jian patted him sympathetically on the shoulder.

"But that's okay, I'll be able to earn it back soon. With these weapons, and my invincible soap, I'm going to kill two hundred of them today. The big black bear straightened up and raised his submachine gun proudly and shouted.

"I just set it up in the team, and when the time comes, the income from the kill points of our bosses will be released to each of our accounts by the system according to their respective contributions, and the system will determine how to contribute."

"You're all set." Lu Yu'an turned around and looked at the three people behind him, and seeing that they all looked ready, he pushed open the electronic door and rushed out first.

The ground that had been blown up by the gas canister yesterday was charred black, and some cracks could be faintly seen.

The corpses of the zombies who died here have all disappeared, and they have obviously been eaten by the other zombies who came from behind, and there are still blood stains on the ground.

Not long after the four of them came out, the aura emanating from their bodies attracted a large number of zombies.

"Break through according to the route drawn up last night." After Lu Yu'an finished speaking, he suddenly rushed towards the zombie with a submachine gun. The big black bear and the psychologist also followed with submachine guns.

Only Yang Jian was still holding the spear and was stunned in place, this is not right, shouldn't he fight with a bayonet? Why are you all holding submachine guns?

"Master, are you stupid, if you don't keep up, you're going to be surrounded by zombies." A light voice sounded in Yang Jian's ears.

"Alice? You can actually speak on your own? Yang Jian looked surprised.

"Master, if you don't leave, I can change the master, the zombies are already behind you." Alice said angrily that his master's mind seemed to be a little out of line.

As soon as Yang Jian turned his head, a zombie opened its mouth and rushed towards him, and the stench in its mouth could be smelled from afar.

Yang Jian knocked it to the ground with a single shot, reaping a few kill points.

"Brother, your bad breath is a bit bad, but you don't need to worry about it anymore." Yang Jian was still talking about it, when he heard a large number of footsteps coming, he looked up and was about to say something, and then he looked at a large number of zombies like a trend.

"Alice, give me a submachine gun." Yang Jian turned around and ran directly, throwing grenades at the back as he ran, regardless of whether he threw it or not.

"Those guys didn't even wait for me." Yang Jian was chased by zombies, and he chased in the direction where Lu Yu'an and the others left.

At this time, Lu Yu'an, who had already run to the door of the community, found a nearby building and hid in, and when they entered the room, they found a zombie rushing towards them.

"Bang"

The zombie was shot in the head by a big black bear with a submachine gun.

"You can do this marksmanship." Lu Yu'an was a little surprised, he thought that he was a psychologist with good marksmanship.

"That's a must, you know, I'm a gun god." The big black bear said proudly. It's not easy, but I can finally get him to put it on.

Lu Yu'an inspected the house and locked the doors and windows to prevent the zombies from smelling them.

The three of them stood by the window and observed the zombies wandering at the entrance of the community.

"There are a lot of zombies."

"It seems to be a commercial street outside the community, and if we drag at the door for too long, it is estimated that it will attract a large number of zombies."

"Well, don't you think we're missing something?"

"What?" Lu Yu'an and the big black bear turned their heads to look at the psychologist who spoke out.

Looking at him first puzzled, and then seeing his empty behind, Lu Yu'an drank the big black bear and glanced at each other.

"Where's Lao Yang?"
