No one knew where the zombies came from, they suddenly appeared, and then swept the world with lightning speed.

Two weeks after the zombies appeared, Su Tian and Su Meng still stayed at home, there were still sporadic zombies outside the villa, the zombies' sense of smell was comparable to that of ordinary humans, but their physical strength was several times stronger than that of ordinary humans, their eyes still maintained their function, and within a few days, the zombie frenzy swept the whole world, except for some humans who survived by chance, most of them turned into zombies.

It seems that the zombie frenzy is caused by an unknown virus, Su Meng can sense the existence of the zombie virus through super sense, and the humans infected with the zombie virus act as a new source of infection, and the zombie virus can be transmitted through contact, air, water, mosquitoes, etc. Zombie viruses seem to infect any living thing, even single-celled ones, and humans or other organisms infected with zombie viruses show decreased intelligence, increased appetite, loss of reason, and instinct for activities.

When the real zombie virus appeared, Su Meng realized that the zombie apocalypse in the previous American dramas was weak.

In those American dramas, the number of survivors will always be large, but the result of Su Meng and her sister observing through the telescope on the rooftop in the past few days is that basically all the humans in the entire city are dead.

The parents of the Su Meng sisters were not spared.

The zombie fly entered the basement of Su Meng's father's company through the vent, and then the survivors of the entire basement first turned into zombies, then attacked others, and finally everyone died.

Su Meng's mother, because she heard the cry, opened the door and went upstairs to check, only to find that the cry was a baby who had been transformed into a zombie, the baby saw Su Meng's mother's mother and pounced on her, with a sluggish look on her face, she was thrown to the ground by the zombie, and then soon turned into a zombie.

At this moment, Sister Su Meng didn't know that her parents were dead, and she was still thinking about how to contact her parents.

In order to deal with the zombie virus in the air and the insects carrying the zombie virus, Su Meng created 100 million nanomechanical insects, and then set the instructions of these 100 million nanomechanical insects to protect herself and her sister from zombie viruses and insects, and then she divided the 100 million nanomechanical insects in the cup into two and a half cups, and drank them separately for herself and her sister.

The nanorobotic worms successfully resisted the increasing concentration of zombie viruses in the air and acted as zombie virus antibodies, making it impossible for Su Meng and Su Tian to be infected with zombie viruses.

Su Meng's ability is almost equal to the low-level version of what he wishes come true, and he needs wisdom to control it perfectly.

The energy in Su Meng's body has been stored to 10,000 standard energy in the past few days, and she has found that many times she can create things that do not require so much mass, and then have powerful functions.

When Su Meng was thinking about how to strengthen her body, the super-technological artificial intelligence suggested to her to make a genetic evolution potion.

So Su Meng created a genetic evolution elixir suitable for his body. At the same time, he collected his sister's genes and made one for her. Su Meng and her sister Su Tian's genes are homologous, but when the two grow up, their genes are also slightly different, so the two cannot use the same genetic evolution potion.

Su Meng and her sister were in the living room, staring at each other, and then injected the genetic evolution potion together.

After the injection, both sisters fell into a coma.

Genetic evolution agents activate human self-protection mechanisms, which are then genetically modified and genetically upgraded in a comatose state.

The injection of the Genetic Evolution Potion is equivalent to opening a door to evolution, and the first stage after the injection is super sense, and the perception will be more acute than that of ordinary humans, able to perceive subtle changes in the air and a wider range of light, as well as a wider range of sound waves.

Su Meng has already turned on Super Sense, and her genes are already at this stage, so she will start the second stage of genetic evolution, and her strength response will be enhanced.

Su Meng's strength will increase by 2-3 times, and then it will continue to increase until it reaches the biological limit and lifts a weight of 400 times its own weight.

The breakthrough between each stage of genetic evolution depends on the battle and training, through which the gene activity is stimulated, so as to make a breakthrough.

About three days later, Su Tian woke up from a coma.

At this time, Su Tian turned on the super sense, and saw a scene in his eyes that he had never seen before, he could directly penetrate the sight of the object, and the visual experience of seeing the subtle pores on his sister's face, and he could also hear the roar of zombies several kilometers away, this magical feeling directly made Su Tian stunned there.

"Ahh Su Tian couldn't help but say.

Seeing that her sister hadn't woken up yet, thinking that her sister was still evolving, Su Tian walked over and picked up Su Meng and put Su Meng on the sofa, so she couldn't let her sister continue to lie on the ground.

About two days later, Su Meng woke up, and in the past two days, Su Tian lived by eating biscuits and yogurt, and finally looked forward to her sister waking up, and immediately ran obediently to her sister.

"Sister," Su Tian said.

After Su Meng woke up, he felt that his strength had increased, and the direct feeling was that his body had become very light, his body had become more flexible, and there was less gap between his feelings and his body, which was a manifestation of increased reactions.

Su Meng took Su Tian to the basement, and then tested his strength, and found that the maximum strength reached 500 kilograms per punch, which was already much more than ordinary people.

Then I tested the speed, and the running speed reached 6.3 seconds per 100 meters, which is also more than the average number of people.

Su Tian was directly stunned next to him, and also tested himself, and found that he was only a little stronger than ordinary people, not as powerful as his sister.

"Sister, why are we different?" Su Tian asked.

Su Meng looked at Su Tian and said, "Sister, I'm in the second stage." ”

Su Tian didn't quite understand: "But I'm in the first stage." ”

Su Meng smiled and explained: "It's such a sister, I have already started the first stage before, so after injecting the genetic medicine, I directly started the second stage, and you are the first time to inject the genetic medicine, so only the first stage has been started." ”

Su Tian looked at Su Meng, and Su Meng continued: "Sister, if you want to reach the second stage like me now, you need to keep fighting, and stimulate genetic evolution through fighting. ”

Su Tian pursed her lips, and Su Meng said: "Sister, let's go out and hunt zombies later, with miniature nanomechanical bugs, we won't be infected by the virus." ”

Su Tian shook her head, she didn't want to fight with zombies: "Sister, let's not go out and fight with zombies, okay?" It's not interesting at all, sister, it's good if you keep me all the time, keep me as a pet. ”

Su Meng didn't expect Su Tian to say this: 'Keep me as a pet', Su Meng wondered if this was really what her own sister said?

However, after Su Meng pursed her lips, she said, "Sister, you know." ”

Su Tian nodded and said, "Sister, you always kiss me secretly at night, and you still say those meaty words, in fact, people have already woken up......

"Don't you hate your sister?" Su Meng said.

Su Meng has a severe sister-lover, although she usually doesn't show it, but at night, she will do something 'affectionate' to Su Tian, she originally thought that her sister was asleep, but she didn't expect to be discovered by her sister, and instantly had a particularly embarrassing feeling, afraid that her sister would hate her.

"It's okay, sister, then keep me as a pet in the future, people really don't like to fight." Su Tian said.

"Sister" Su Meng said, her eyes showed that she was very excited, and the burden in her heart was finally let go.
