However, many years later, people really understood that the cause of genetic mutations in animals and plants was the genetic weapons secretly developed by various countries, and at first the development of genes was only in the treatment of diseases, gradually improving to change the physical fitness of human beings, so that human strength was stronger, faster, and more explosive. Subsequently, various genetic drugs were used in large quantities in the army. After all, once a war breaks out, casualties are also one of the important factors to measure victory, so later countries began to develop genetic agents that change large beasts to make them more aggressive, and plant subconscious genes that do not harm specific people in their subconscious. In just a few years, new species have been reported in various countries, but what people don't know is that many of these species are genetically modified by humans or the offspring of genetically modified organisms and other organisms. The hallmark of their unification is their ugly appearance, whether they are faster or more powerful, and some even have alloy-like defense, and the ability to recover from severed limbs.

The increasing number of incidents of animals hurting people did not wake up the politicians of the time, who only knew the rule of survival that only with a strong fist had the right to speak. In order to prevent the recurrence of pet injury incidents, countries have only introduced various strange legal provisions to prohibit private domestication of pets, and the whole people have killed and injured pets.

After the event, there was a big turning point in the year 2120, and there were large-scale animal siege events in many places around the world, and most of the animals besieging the city were evolved and mutated, with a certain amount of intelligence, larger size, stronger attack power, higher defense power, and faster speed! Because the animal siege incident happened very suddenly, human beings suffered heavy casualties, and the world's population increased from the original 7 billion, and after this incident, less than 3 billion remained. Especially in coastal cities and small towns near forests and grasslands, there are even more massacres. Island nations like Japan, perhaps because of the overfishing of marine life, especially Great white sharks and other large creatures themselves have a certain wisdom of the ocean, through mutation and evolution into the ocean overlord, but also some marine creatures directly evolved into amphibians, in the fierce siege of Japan and other island countries, after Japan for several months of perseverance, I don't know whether it is a disaster caused by marine life, or a natural disaster, many volcanoes in the Sea of Japan continue to erupt, resulting in a 9-magnitude earthquake, under the siege of internal and external troubles, Japan did not escape the fate of the country in the same year. Zhou Yiyang then looked back, Japan also sank most of the time in the earthquake, and now Japan has completely become a forbidden area for human beings. Many small and weak countries have survived in name only, and human greed has led to large-scale riots in many regions. The war between the alien beasts and humans continues, and the only countries that can gradually protect themselves are China, the European Union, Soviet Russia, the United States and Australia. After the large-scale animal siege incident, all the small cities and towns around the world were spared, either slaughtered or transferred to the safe area in time, and our country has built five major security areas, namely the northwest region, the southwest region, the Central Plains region, the northeast region and the southeast region. Each main security area is divided into many small security areas, and the district where Zhou Yiyang is located is Dongcheng District in the northwest district. In the aftermath of this massive animal siege, all small towns around the world were spared, either slaughtered or moved to safety in time.

Seeing this, Yi Yang took a deep breath and muttered:

"What happened?" After closing the book, Zhou Yiyang couldn't calm down for a long time.

"It's really a crime made by God, and you can't live if you do it yourself!" Zhou Yiyang walked to the window silently with emotion, and his heart was still shocked by the content of the book.

"What kind of world am I in, I really want to go out and see it soon!"

At this time, Zhou Yiyang was full of expectation and curiosity about this familiar and unfamiliar world, and felt deep regret for everything that human beings had done.

"Out of the safe zone, the outside world is not like a primitive society, human beings and animals compete for living space and feed each other, the outside world is rampant, ordinary people are like rats in Tibet, you must feel it when you have the opportunity. Zhou Yiyang's mind appeared in the primitive world of the movie, and even the picture of the Jurassic era. Zhou Yiyang, who was infinitely crooked in his mind, came to the window of the living room and leaned on the window to look out, the clouds and mist outside the window were white and vast, and he couldn't see the distance at all.

"It seems that the smog problem has not been solved after so many years. As he spoke, he stuck his head out of the window and looked down.

"Oh my god, why is it so tall. The moment she looked down, Zhou Yiyang's heart seemed to be about to jump out, and then she realized that the white smoke was not haze at all, but a cloud formed by fog.

There was a sound of opening the door ...... "Click", the door was slowly opened, and Li Qing, who was wearing a school uniform, walked in.

"What are you doing in front of the windowsill, your clothes are stripped naked, you can't think about it, you want to jump off the building!"

"How high does your family live?" Zhou Yiyang asked without paying attention to Li Qing's teasing.

"On the 125th floor, look at your cowardice, do you see that your legs are too high and scared, and you don't have the courage to die. Li Qing continued to tease Zhou Yiyang in a contemptuous tone!

"125?!" Zhou Yiyang couldn't help but speak.

"Cut! old antiques, dirt buns. Li Qing, who glanced at Zhou Yiyang, said disdainfully. and walked to the room where Zhou Yiyang slept. After a while, Li Qing walked out again. "Did you see that history book I put on my bedside table?"

"Oh! I just looked, I'll look for you!" he said and walked to the room.

"How can you touch my things casually, it's not qualified!" Li Qing glared angrily as Zhou Yiyang walked into the room, and then followed.

Zhou Yiyang, who was already unreasonable, did not argue with Li Qing! Walking into the room, he found the "History of World Civilization" under the messy quilt, and cleaned up the pig-like bed, Zhou Yiyang lowered his head embarrassedly and handed the history book he found to Li Qing.

When Li Qing reached out for the book, Zhou Yiyang saw obvious scratches on Li Qing's wrists.

"What's wrong with your hand?" Zhou Yiyang grabbed the book and didn't let go of it immediately, staring at Li Wan's wrist and asked.

"Nothing, I just fell while walking. Li Qing said very indifferently, and pulled the book that Zhou Yiyang was holding hard, but he never pulled it over, and said angrily:

"You let me go, I still have something, don't delay me. After Zhou Yiyang let go of the book, he found that Li Qing's school uniform had obvious traces of pulling, although it had been sorted out, there were still some small traces when looked closely.

"Are you being bullied? You also have scratches on your clothes. Zhou Yiyang looked at Li Qing and said with some distress.

"You don't care, I can take care of myself. Seeing that Zhou Yiyang really cared about himself, Li Qing's stubborn heart also softened, and he said lightly.

"Why don't I go to school with you, I'll protect you. ”

"Cut! Just protect yourself, who can you protect. Li Qing squinted and looked Zhou Yiyang up and down, and deliberately said in a disdainful tone.

"Hehe, Sister Qing, that's right, in fact, I just want to go out and see the outside world, and after reading your book, I'm really curious about the outside. ”

"Feel free to do so, as long as you don't get me into trouble. Li Qing said lightly, deep down in his heart, he didn't want to take Zhou Yiyang out, but living in the chaotic environment of the edge of the city, every time he went out, it was like going through a catastrophe, and taking Zhou Yiyang with him might make the little gangsters who often harased him restrain him.

"Okay, let's go. Zhou Yiyang looked excited and couldn't wait to stand outside the door, waiting for Li Qing to close the door and go downstairs together.

"Can you see people like this? Li Qing looked at Zhou Yiyang, who was standing outside the door, a small lady's jumper, big pants, and ill-fitting slippers.

"I think it's okay. Zhou Yiyang glanced up and down at himself and said:

"Okay, just wear some of them, let's go quickly, you're going to be late in a while." Zhou Yiyang couldn't wait to urge.

"Hey, I'm going to kill you!" Li Qing ignored Zhou Yiyang, turned around and walked into the master bedroom, and when he came out, he took a military-colored long-sleeved shirt and handed it to Zhou Yiyang and said:

"This is what my father left, you can wear it first, just lend it to you, it must not be broken. ”

"Got it, I'll take care of it. Zhou Yiyang took the clothes, stood outside the door and took off the jumper, and put the army green shirt that was one size bigger on his body.

"Alright. Let's go, or you're going to be late. Zhou Yiyang didn't even button his clothes, so he urged Li Qing to close the door.
