My mother and I were completely stunned. Listening to what my aunt said, there were only three words in my mother’s and my mind: Impossible!
“Sister, what are you talking about? Could it be that you’ve been so traumatized that you’re confused?” My mother’s tone sounded full of doubt.
It’s no wonder my mother asked this. After all, what my aunt said was really hard to believe.
“Ah...” The eldest aunt, who was lying on the sofa and covered with the same quilt as the second aunt, sighed. She looked at my mother and me and said slowly: “If the facts were not in front of me, I would not believe it.”
“Anyway, the world has become like this now, so it doesn’t matter even if I tell you.” My aunt’s tone didn’t sound like she was lying.
“Caitlin, tell me honestly, do you remember what the first zombie that bit you looked like?” Aunt called my mother’s nickname again.
And while my aunt was speaking, two streams of milk spurted out from her huge breasts, wetting two patches of her quilt.
I had already secreted a lot of milk, but I didn’t expect so much milk to come out. What a waste.
My aunt was a little embarrassed and covered her breasts that were constantly gushing out milk with her arms, waiting quietly for my mother’s reply.
Fortunately, my mother’s thoughts were not disturbed by my aunt’s milk, and she was seriously recalling the moment when she was bitten by the zombie.
“It was a female zombie ... she was wearing a black coat ... and had short hair...” Mom recalled the scene when she was bitten.
After my mother finished her description, my aunt sighed again, smiled bitterly and said, “If I was only 80% sure just now, now I am 100% sure.”
“Aunt, you really didn’t lie to us?” I couldn’t help but interrupt.
Not only me, but my mother also doubted whether what my aunt said was true. But after thinking about it, I realized that there was no reason for my aunt to lie to us.
Could it be that she just wanted to tease us in this apocalypse? To relieve some stress? It was obvious that this was impossible.
Then, my aunt took a deep breath and told the secret that she had been hiding.
At first, my mother and I didn’t react, but as my aunt continued to talk, our expressions gradually changed from surprise to astonishment, and then from astonishment to shock.
Before the end of the world...
My aunt has been engaged in research related to biological sciences for a long time, but she has never told outsiders what she is researching specifically.
To be precise, she hid not only outsiders, but even her blood relatives. Her three younger sisters only knew that their eldest sister had devoted herself to research after graduation and rarely came home.
Whenever Lauren, Caitlin and Molly couldn’t resist their curiosity and asked her about work, Whitney, as the eldest sister, would change the subject and talk about family matters.
The younger sisters found out that their eldest sister was concealing the truth on purpose, so they stopped asking any further questions.
After all, they are all adults who understand reason. Considering that the eldest sister Whitney works in a state agency and has kept it a secret from her family ... it must be something that is not convenient to disclose.
In fact, my mother and her sisters were right in their guess that my aunt Whitney was indeed doing something that could not be disclosed.
Biological virus research!
Although my aunt was young at the time, she still became a researcher with a special status because of her talent and excellent ability.
My aunt didn’t tell us how she was recruited as a researcher, which wasn’t the point, so my mother and I didn’t ask.
She continued.
There is a biological research institute in the suburbs outside this city, which is not shown on the map. Because it is located in a remote area, there are usually few people wandering around. Even if there are, soldiers with live ammunition will soon come over and politely ask you to leave.
My aunt Whitney worked in biological research at this institute for more than ten years.
Over the past decade, my eldest aunt has transformed from a young and confident girl into a researcher; my second aunt has transformed from an elegant and noble swan-like goddess into the mayor’s lover; my mother Caitlin has transformed from a delicate and charming girl into a sexy mother who loves her son very much; my youngest aunt Molly has transformed from a cheerful and sunny girl into a heroic policewoman.
Over the past decade, my aunt has conducted countless biological studies and achieved some good results.
In the research institute, my aunt’s work was to enhance human genes and cells, and she successfully researched several types of protozoa.
One of them is beneficial to the human body, can effectively prevent human aging, enhance immunity to a certain extent, improve body functions, and keep a person’s appearance and figure in an ideal state.
This discovery greatly encouraged my aunt. After all, she had personally researched something that could enhance human genes. This sense of accomplishment was incomparable to ordinary things.
So on this basis, my aunt improved it and named it C1.
Not long after, the top management of the institute held a meeting. After seeing the achievements created by my aunt Whitney, they decided to provide encouragement and financial support.
With the support and funding from senior management, my aunt put all her energy into trying to develop C1’s potential to its fullest.
Not only that, my aunt also injected herself with C1, which is why when I first saw her later, her appearance was in no way inferior to my mother who had been enhanced by the virus.
Three years later, C2 was successfully manufactured.
The C2 prototype is the painstaking work of my aunt and several colleagues. It can enhance the human body’s capabilities twice as much as C1, and can even increase the human body’s lifespan limit.
However, there is a fatal flaw - if you plan to inject the C2 antigen, the mortality rate is eighty percent!
The mortality rate is too high. Even if it is reduced by half it would be unacceptable.
The reason why the top management of the research institute supported my aunt’s research was because the C2 precursor was to be given to some important people to strengthen their bodies and prolong their lifespans!
For those important people, let alone an 80% mortality rate, even a 10% mortality rate is a huge risk.
Therefore, the top management of the institute issued an order that my aunt must improve the C2 prototype as quickly as possible to reduce the mortality rate to a minimum.
For my aunt, no matter how difficult the problem was in the past, she had never been stumped. However, at this moment, she was at a loss.
Although she has innate talents and acquired abilities, Auntie also has her limits. After developing the C2 proto-body, her limits can no longer be broken.
Until one day...
That day, a new type of virus was sent to the research institute. After analyzing it, my aunt and several other researchers were surprised to find that this was actually a terrible virus with extremely high contagiousness!
It can be transmitted through water and air, and its mortality rate is 100%, with no chance of survival.
Although this virus is extremely dangerous, after several months of careful research, my aunt discovered that this virus can actually be used to improve the C2 protozoan!
So, my aunt fell into crazy research work again. Fortunately, she injected herself with C1 antigen, otherwise such a horrible workload would definitely exhaust her body.
With huge funding support and non-stop research, two years later, my aunt created the C3 prototype.
After another half a year of biological experiments, countless animals and death row prisoners who were secretly sent to the institute were injected with C3 antigen by my aunt for observation and experiments.
It is called a protozoan, but in fact it is more like a virus.
Because C3 will destroy the body’s original cells and replace them, making drastic modifications and enhancements to the human genes.
If the cells and genes in the human body are a building, C1 and C2 are to reinforce the building and decorate it better; C3 is to directly demolish the original building and rebuild a taller, bigger and stronger giant fortress, which is exactly the relationship between parasite and host.
However, the effect is also very powerful.
The host injected with the C3 entity will have its bodily functions enhanced to an unimaginable level. As long as there is enough energy supply, the host’s physical abilities can be enhanced to a terrifying level.
Not only that, it also enhances memory, reaction, willpower, metabolism, physical recovery, thinking ability ... all aspects of the human body!
However, the C3 protozoon ... no ... to be more precise, it should be a virus...
The C3 virus was developed by fusing another extremely dangerous virus with the original C2 virus. Although it will not cause death to the human body, it has many side effects.
The biggest side effect is desire.
According to experiments on animals, once injected with the C3 virus, the host’s desires will be greatly amplified.
After a monkey was injected with the C3 virus, it raped three other female monkeys within half an hour, one of which was even raped to death; the monkey injected with the C3 virus then ate the remaining two female monkeys, and then raped the dead monkey’s corpse.
Appetite ... sexual desire ... is magnified to a terrifying degree...
Such side effects cannot be used on humans.
So, my aunt teamed up with Dr. Kevin and several other experienced doctors and spent half a year improving the C3 virus.
Hard work pays off. The side effects of the C3 virus have been greatly reduced, and there is no longer any appetite or strong sexual desire; some other side effects have also been completely eliminated.
However, during the improvement process, a new side effect emerged.
The modified C3 virus will cause the host to have an abnormally strong sexual desire when it is infected for the first time. This sexual desire is very unique and will only produce sexual impulses towards one’s own blood relatives. The stronger the blood relationship, the stronger the impulse; if one does not have sexual intercourse with one’s own blood relatives within five hours, the body’s organs will gradually fail and lead to death.
However, this is just the beginning.
During sexual intercourse between the host and his blood relatives, the C3 virus in the body will infect the other party, and both parties will become C3 virus hosts.
Moreover, under the influence of the C3 virus in their bodies, the two parties will establish an extremely special relationship, which my aunt named partner symbiont.
At first, my aunt and several other doctors were shocked and puzzled by this phenomenon. Although they did not understand the reason in subsequent research, they figured out the special relationship between partner symbionts through a brief observation.
My aunt’s summary in her notes is as follows.
