National Gardener: I can choose the evolution path of spiritual plants.

Chapter 220: Crazy

"It is inevitable that we will be discovered. I just hope that the demon virus can be discovered later."

Lin Zhi stopped worrying about these things, got up, went into the kitchen and started cooking.

……

Morning on the fourth day of virus release.

Lin Zhi woke up from his sleep and checked the system panel as usual.

After a day, the number of infected people increased by several thousand, and the number of infection points exceeded ten thousand.

"Great, I can finally continue to strengthen the virus's capabilities."

Lin Zhi had a hunch that if the virus's ability was strengthened once more from the advanced level, changes that he could not imagine might occur.

After thinking about it, he spent 1 infection points to enhance the virus's infection ability.

As the infection capability upgraded, new changes appeared in the system interface.

Virus:Demon Virus
Evolution level: E
Enhancement level: lv4
Virus effect: Emotional excitement (makes the infected person emotionally excited and unable to control their emotions easily. When encountering a situation where their emotions fluctuate violently, there is a high chance that their emotions will get out of control.)
Virus Capabilities

Extreme: Droplet transmission: The virus host can release the virus into the outside world when talking or sneezing. The virus exposed to the outside world can survive for 40 minutes in a non-toxic environment below 30°C and can float in the air to infect new hosts.

Primary heterogeneous transmission: The virus acquires the ability to infect all mammals.

……

Infection Enhancement: lv4 (0/10)
Resistance Enhancement: lv3 (0/10000)

Spread Enhancement: lv3 (0/10000)

Adaptation Enhancement: lv3 (0/10000)

"The virus has evolved? Is there a threshold of 3 levels? And it has this new ability to infect all mammals?"

Lin Zhi was surprised and happy.

What is surprising is that the virus evolved from F to E, and the side effects are even greater.

The more harmful the virus is, the easier it is to detect and treat.

If the virus is not even as harmful as the common cold virus, then it will definitely facilitate its spread.

The good news is that with the emergence of new capabilities, the range of infection of the virus has been greatly expanded.

In addition to humans, there are also a large number of pet dogs, pet cats, and rats in the sewers.

These animals are not only numerous and highly mobile, but also have good concealment capabilities.

Especially the rats in the sewers are a breeding ground for viruses.

Animals are simple in nature and can clearly distinguish between good and evil. For example, competition for food, territory, and mates can easily give rise to evil thoughts.

After strengthening the virus, Lin Zhi's life returned to his idle life.

His daily routine is to lie in the villa, cook and eat, look at the system panel, check the news on his mobile phone, play games, and watch videos.

There was no way. Lin Zhi was unfamiliar with the Ghost Country and couldn't speak the language, so there was no gain or meaning in going out.

As for the virus transmission system, it currently has no other functions except strengthening the virus, and we can't keep an eye on it all the time.

Two days of this daily routine passed, and the number of infected people (mammals) exceeded 10.

This is due to the increased ability of the virus to spread to mammals.

At first, pet dogs and cats were infected, followed by rats foraging in the sewers and stray cats and dogs outside.

The infection of mammals once again increases the chances of humans being infected.

As time goes by, the emotions of humans or animals infected with the demon virus are subtly amplified and it becomes increasingly difficult to control themselves.

Some people or animals with poor self-control may even exhibit exaggerated behavior after suffering emotional trauma.

For example, there has been a surge in crimes such as attacks on others, murders in moments of passion, fights, robberies and rapes.

Some administrators and managers also acted emotionally and aggressively when formulating legal plans.

During this period, Lin Zhi consumed another 10 infection points, further strengthening the virus's infection ability and upgrading it to LV5.

After the upgrade, in addition to the enhanced droplet transmission ability, a new transmission route has been added: infected reptiles.

Animals are divided into vertebrates and invertebrates. Vertebrates include fish, reptiles, amphibians, birds and mammals.

Common reptiles in human society include snakes, turtles, geckos, etc.

This undoubtedly added a lot of transmitters to the spread of the virus.

If the virus did not need to multiply in the body for a period of time before it could continue to infect others, the number of infections would not have exceeded 10 by now.

Lin Zhi has a hunch that in a few days, when the virus concentration in the current infected people reaches a certain level, the number of infections will begin to grow exponentially.

something unexpected may happen any time.

When Lin Zhi opened the news on his mobile phone as usual, he found out that the virus was discovered by scientists from the Ghost Country!
Research report on unknown epidemic viruses

The author is "Jūrō Inaka", a medical scientist from the Ghost Country.

Lin Zhi curiously clicked on the news:
Recently, many people in society have developed fever and a sudden increase in appetite. Medical scientist Juro Inaka discovered that this is a new type of virus.

There is no need to panic. Although there is no specific medicine or vaccine for this new virus yet, its harm is not serious.

At present, scientific research has found that the main symptoms of people infected with the new virus are a sudden increase in appetite, emotional instability, and fever.

For fever symptoms, common antipyretics can effectively treat them.

Emotional instability can be treated with some sedatives prescribed by the hospital.

As for the sudden increase in food intake, it is not caused by the virus, but the body needs more nutrition to resist the virus.

Therefore, citizens infected with the virus should avoid going out unless necessary, isolate at home, and carry plenty of antipyretics and sedatives to effectively treat the harm caused by the virus.

As for when the virus will be cured, there is no need to worry too much. Scientists will soon develop a vaccine and a specific medicine for the virus.

The results of laboratory experiments show that this virus is not resistant to high temperatures and has a short survival time in the outside world...

Based on the characteristic that the virus's nucleus shell is shaped like a cow's horn, the virus is tentatively named "cow horn virus".

Radiation Island, National Institute of Research.

101Lab.

Juro Inaka was wearing protective clothing, wrapping his body tightly.

He removed a dish of petri dishes from the incubator and placed it under the ultra-precise microscope.

"Reagent 41"

Upon hearing the sound, the assistant beside him immediately took out reagent numbered 41 from the laboratory cabinet and handed it to him.

Juro Inaka dropped the reagent into the petri dish and then heated it over an alcohol lamp.

Then cool and continue heating.

so cycle.

After about dozens of cycles, the liquid in the petri dish changed color.

The color changed because the research on the reagent for detecting the rabies virus was successful.

As we all know, viruses are a non-cellular life form, which consists of a long nucleic acid chain and a protein shell. Viruses do not have their own metabolic organs or enzyme systems. The most important substance is the central long nucleic acid chain, also known as DNA or RNA, which can replicate, transcribe, and translate through the host organism to reproduce new viruses.

Different viruses have different nucleic acids.

Therefore, if you want to detect the presence of the virus, in addition to visual observation and indirect sampling and observation, the simplest and most efficient method is to detect nucleic acid.

The method is difficult to explain and is very complicated, and it is difficult for non-professionals to understand.

It is said to be simple, and it is actually very simple. The relevant knowledge and principles are taught in high school biology classes.

First, it is necessary to analyze the sequence composition of DNA or RNA in the viral nucleic acid.

Taking the bovine rabies virus as an example, we first analyze the DNA sequence composition of the bovine rabies virus, and then compare its sequence composition with other known DNA sequence compositions.

The unique DNA fragments of the rabies virus were screened out through computers.

Next, an artificial method, the same process cycles and a specific enzyme (DNA polymerase) are used to amplify this unique DNA fragment.
In this way, there were only trace amounts of this DNA fragment in the culture dish, but it was artificially replicated and amplified instantly into countless numbers of this DNA fragment.

By adding fluorescent genes to this reaction process, it is possible to detect with the naked eye whether the virus in the culture dish has changed.

For example, make a tube of reagent for detecting bovine leukemia virus, and then extract human saliva, blood, etc. and put it into the reagent.

Then the "catalyst" is added, and if there is no rabies virus present, no reaction will occur.

If the virus is present, a reaction will occur.

This reaction is invisible to the naked eye, but after adding the fluorescent gene, when the virus fragment is amplified to a certain extent, it can be seen.

"Polymerase No. 41 can react with the specific fragment of bull madness. Report this result to the dean and start producing the test reagent."

Juro Inaka put down the petri dish and started a new experiment.

On the other hand, in Radiation Island, the Cabinet Office, Prime Minister Kosha Hosoyuki convened ministers from various departments and held a meeting on the prevention and control of the rabies virus.

"Do a good job in popularizing science, supplying materials, calming people's emotions, isolating and treating them, and targeting criminal incidents..."

The fifth day of virus release.

The number of infections has exceeded 20.

Lin Zhi strengthened the other three abilities of the virus.

Virus:Demon Virus
Evolution level: E
Enhancement level: lv5
Virus effect: Emotional excitement (makes the infected person emotionally excited and unable to control their emotions easily. When encountering a situation where their emotions fluctuate violently, there is a high chance that their emotions will get out of control.)
Virus Capabilities

Extreme: Droplet transmission: The virus host can release the virus into the outside world when talking or sneezing. The virus exposed to the outside world can survive for 50 hours in a non-toxic environment below 1°C and can float in the air to infect new hosts.

Intermediate: Heterogeneous transmission: The virus acquires the ability to infect all mammals and reptiles.

Extreme Camouflage: After infecting the host, the virus can disguise itself as normal bacteria to further intercept nutrients in the human body, and has a 50% chance of being detected by the immune system.

Primary Steal: A virus can disguise itself as a beneficial bacterium and steal a related ability.

Extreme immune deception: After the virus infects the host, each virus monomer has a one in ten billion chance of inducing the immune system to kill normal cells and disguise and replace them.

Primary replication: A virus that successfully camouflages itself will have a one in a trillion chance of replicating new offspring.

Extremely adaptive: When a virus infects different hosts, is harmed by common drugs, is affected by the environment, or is attacked by the immune system, it will adapt and grow slightly to compensate for its shortcomings.

Primary mutation: After the virus is damaged by drugs, affected by the environment, or attacked by the immune system, there is a one in a trillion chance of an adaptive mutation.

Infection Enhancement: lv5 (0/100)
Resistance enhancement: lv4 (0/10 million)
Spread Enhancement: lv4 (0/10 million)
Adaptive Enhancement: lv4 (0/10)
The virus was further strengthened, and the number of cases increased dramatically on the 5th day of the virus release.

However, on the 6th day, the infection rate dropped suddenly.

Lin Zhi learned that the reason for the slowdown was that official decrees were being issued from all sides, and the society on Radiation Island was gradually returning from chaos to order.

As a result, society basically stopped functioning and everyone was isolated at home, preventing further transmission of the disease.

At the same time, the Radiation Island authorities launched an operation to capture stray cats and dogs, and to eliminate rats in the sewers.

So for a while, the infection rate dropped to freezing point.

But the number of infection points continues to grow.

Lin Zhi knew that this was mainly due to the official activities of killing stray cats, dogs and rats.

There are three main sources of infection points:
When life is infected for the first time, 1 point per person.

The infected are killed, 10 points per person.

The infected person's survival time, 1 point/day.

Therefore, every day that passes, even if there are no new infected people, the old infected people can continue to provide infection points.

The official killing operation provided Lin Zhi with a large number of infection points in a short period of time.

On the sixth day after the virus was released, Lin Zhi consumed 6 infection points and strengthened the other three aspects of the virus to level 30.

The accumulated infection points were once again used up.

On the 10th day after virus release, the remaining number of infected people/animals was 21.

The accumulated infection points reached 100 million. Considering the current transmission obstruction and the imminent targeting of the medical community on Radiation Island, Lin Zhi spent another 100 million infection points to enhance the virus's adaptability.

When the adaptability is upgraded to level 6, the effect is very impressive:
Extremely adaptive: When a virus infects different hosts, is harmed by drugs, is affected by the environment, or is attacked by the immune system, it will adapt and grow to a moderate degree to compensate for its shortcomings.

Advanced mutation: After the virus is damaged by drugs, affected by the environment, or attacked by the immune system, there is a one in ten trillion chance of an adaptive mutation.

"The chance of this mutation seems to be only one in ten trillion, but the number of viruses is extremely large. Once infected, they can multiply rapidly. With such a large number of viruses, there will always be successful mutations."

Lin Zhi knew that if a miracle happened, it must be because of the ability of mutation.

……

Day 11 of virus release.

Virus testing reagents have been mass-produced and put into use.

Seriously ill patients were sent to designated hospitals for treatment, and clinical trials for the treatment of the virus were also launched one after another.

As the sun rises and the moon sets, the medical staff on Radiation Island conduct various treatments and experiments on those infected with the virus.

Stimulated by a wide variety of drugs, the virus began to slowly adapt.

A large number of viruses are killed, and stronger viruses appear and multiply, and some drugs quickly lose their effectiveness.

As old drugs become ineffective, new ones are developed.

At the same time, tankers filled with disinfectant were everywhere in the city for carpet disinfection.

Stray cats and dogs have been killed, and even the birds in the sky have been affected.

In addition to daily disinfection and the placement of rodenticides in urban sewers, the authorities have even set up a special rat extermination team to search the sewers.

99% of the rats died, which triggered fear among the rats.

An uneasy, gloomy mood was brewing among the surviving mice.

These mice had severe mood swings, and under the influence of the virus, each one became extremely crazy.

They even rushed out of the sewers and attacked humans.

For a time, Tokyo Daily reported many cases of rats breaking into homes and injuring people at night.

Although the mortality rate from being bitten by rats is very low, viruses can be transmitted.
