After graduating from university, Gu Yanan decided to study abroad, and Gu Qingcen also chose the same path.

The two went to the same research institute abroad, with similar majors and different mentors.

After two months abroad, Gu Yanan was always surrounded by many excellent boys, Gu Qingcen had the urge to beat these boys, he felt that he should explain his words to Gu Yanan, so he decided to confess.

But a few days before he was ready to confess, when he was doing experiments in the laboratory, he suddenly noticed that his hands would tremble unconsciously.

At first, Gu Qingcen thought that it might be because of the recent mental stress and overwork.

After two days of rest, the symptoms did not lessen at all.

Gu Qingcen began to feel worried in his heart.

Recalling the experience of her mother Li Xiaowan before her death, the muscles on her face and hands would also tremble involuntarily, and then she had depressive symptoms until she finally committed suicide.

And he himself is now suffering from similar symptoms, involuntary tremors of his hands, a recent fiery temper, and mental depression......

Could it be that my mother committed suicide because of illness? And the disease can be hereditary?

The more Gu Qingcen thought about it, the more worried he became, so he found a time to go to the hospital for an examination.

He told the doctor in detail about his family, his mother's symptoms before she died, and his own current symptoms.

The doctor advised him to do genetic testing.

The results came back a few days later.

The genetic test report clearly states that it is a carrier of the HTT mutated gene.

There is more detailed testing data on the report sheet, and the number of CAG repeats in his htt gene is 57, which has exceeded the limit of 39 repeats.

Gu Qingcen tested a strand of hair left by his mother and found that the number of CAG repeats in the htt gene in his mother's body was 43 times.

He has Huntington's disease, which runs in his family!

Gu Qingcen studied medicine and knew the horror of this family genetic disease.

The mother developed the disease in her 30s, and the number of CAG repeats in his genes was higher than that of the mother, and the onset time would be before the mother.

There is currently no cure for Huntington's disease, which runs in families, and once it develops, people live only a few years.

Now that he is only 22 years old, he already has symptoms of involuntary muscle tremors, and his mood depression is also a symptom of a genetic disease.

The genes for the familial disease in his body have begun to show symptoms, and he has not much to live.

The results of the hospital's examination disrupted Gu Qingcen's plan and shattered his dreams for the future.

Since you can't accompany the person you love through a full life, it's better to leave quietly and leave her without any pain.

Gu Qingcen put away the prepared confession love letter, and left quietly alone, leaving no clues, nor saying goodbye to anyone, the whole person was like evaporating from the world.

After leaving the Institute, he joined Médecins Sans Frontières.

Wherever there is war, where there is pestilence, where there is poverty, where there is backwardness, he goes.

During the nth Ebola outbreak in a region of Africa, Gu Qingcen entered a village with a medical team.

Because of the Ebola epidemic, the people in the village were almost dead, and Gu Qingcen found a little boy who still had a trace of breath from the pile of dead people.

The little boy had brownish-black skin and was covered in blood.

The other members of the medical team all felt that the little boy was in an advanced stage and could not be saved, so it would be good to give humanitarian resettlement, but Gu Qingcen did not give up and took care of the little boy all the time.

A few days later, the little boy who was dying turned out to be getting better little by little.

As the Ebola outbreak gradually came under control, the little boy made a full recovery.

Although the little boy has recovered, all his relatives have died in the epidemic, and even the entire village has died, and the little boy is now helpless.

In the process of treatment, the little boy was very dependent on Gu Qingcen, and when he was fully recovered, the little boy wanted to follow Gu Qingcen.

Gu Qingcen is alone, and he doesn't have any savings, it is not easy to support himself, how can he support a little boy again.

After thinking about it in every way, Gu Qingcen decided to put the little boy in the local orphanage first, and promised the little boy a one-year period, and after a year, he would be taken out of the orphanage when Gu Qingcen saved enough money.

Before leaving the orphanage, the little boy asked Gu Qingcen, "Why is there such a terrible thing as Ebola virus in the world?" ”

Gu Qingcen thought for a while and replied, "They are not terrible, they are messengers sent by God to cleanse mankind, those who are purged are the weak, and those who remain are the strong." ”

The little boy seemed to understand, "I stayed, I'm a strong man?" ”

Gu Qingcen touched the little boy's head, "Yes, you are a strong man who was left behind." ”

"What about you? You have also experienced this plague and survived, and you are also strong. ”

Gu Qingcen thought of the HTT mutant gene in his body and smiled bitterly, "The Ebola virus didn't cleanse me, but God sent other messengers to deal with me." ”

"What messenger?"

"You'll understand later."

After Gu Qingcen left the orphanage, in addition to the activities of Médecins Sans Frontières (MSF), he began to apply for jobs in large medical companies.

During a job application, he inadvertently rescues his twin brothers, Mike and David, who have been kidnapped.

Later, it was learned that the twin brothers were the majority shareholders of the company he was applying for.

In order to express his gratitude, his brother Mike gave Gu Qingcen a sum of money and hired him to work in the company, and the two became friends.

Mike and David's parents were robbed and killed by an addict in their early years, because of the large inheritance left by their parents, and the two were often blackmailed and even kidnapped, and the kidnappers Gu Qingcen met this time turned out to be their relatives, so the twin brothers saw through the warmth and coldness of the world, and even resisted everyone.

When Gu Qingcen told Mike about the human cleansing plan, intentionally or unintentionally, Mike was amazed by Gu Qingcen's thoughts.

Gu Qingcen said that he wanted to use artificial methods to accelerate the process of human evolution, cleanse the weak in the human race, and the remaining elites should exist in this world.

The cleaning method he uses is highly pathogenic pathogens like the Ebola virus, which weeds out people with weak immunity and leaves people with strong immunity.

At the same time, some more vaccines will be made to keep the smart elite of humanity.

Mike is very supportive of Gu Qingcen's crazy idea and is willing to invest a lot of money in him.

A bioterrorist group dedicated to the human cleansing program was established.

Mike invested money and set up secret laboratories in several cities.

To complete the human cleansing program, the most powerful biological weapons must be invented.

At present, the most powerful pathogens on the planet are plague and anthrax in bacteria, and Ebola in viruses.

The fatality rate of the Ebola virus can be as high as 90% or more, which is higher than that of anthrax and plague.

However, the Ebola virus is not easily transmitted, and so far natural foci have been confined to tropical Africa.

It would take a lot of experimentation to invent a pathogen that is highly lethal and very easily transmitted.

At this time, Gu Qingcen's expertise came into play, and he led the entire experimental process, during which he took the little boy from that orphanage in Africa and gave the little boy a new name - Qingnan.
