The process of cultivating extraordinary viruses is indeed a bit like the plague company in the game. Relying on some quantum resonance between soul forces, yak has successfully realized the synchronous evolution between different viruses.


    That is, people far away in the two empires were infected with the same virus. As long as he wants, he can make the viruses in the two patients mutate at the same time. This is also the most abnormal ability of the virus in the plague company.


    The originally non lethal virus can suddenly become fatal after infecting the patient. Therefore, the basic idea of the game is to be crazy about the infectivity of the virus at the beginning, and then basically do not point to the pathogenicity. After it spreads to the world, it can be taken away before countries around the world have a sense of crisis.


    Of course, what yak has to do is not so crazy, but it is still necessary to ensure that all humans on this continent are infected with his virus. Therefore, the infectivity of this kind of virus will be very high in the early stage.


    In order to maintain its own survival, the virus itself also consumes considerable energy and destroys many cells. Therefore, there is a strange flu on the mainland.


    Almost everyone has a fever and recovers completely in a day or two. Even the elderly are rare. Their lives are in danger because of this flu.


    "It seems that the test results are good. Among the 10000 samples of young people, there is no death or disability. It is a qualified virus sample.


    Even the elderly and the frail have a mortality rate of only one in ten thousand, and can begin to improve the transmission capacity of this influenza. " The interface in front of yak is like a real plague company. As long as he chooses a mutation, the virus in all patients will have the same mutation.


    "Let''s start with droplet transmission! But we have to add a sneezing symptom to accelerate the spread of this infection. Well... If you sneeze alone, it''s not a problem as long as it''s not allergic." Yak talked to himself in his mind.


    "I think it''s necessary for you to rely on biological transmission, such as flies, mosquitoes or mice, although the level of civilization in the soul master world looks very high. Soul guides like household appliances are about to appear.


    However, the life of civilians on this continent is actually quite poor. The level of civilization is between the middle ages and the early stage of the industrial revolution, and the level of sanitation is even worse. They don''t even have a special drainage channel to dump household garbage in it. In ordinary people''s houses. There are many flies and mice. I have probably observed their lives. No one cares whether the rest of the food will be patronized by flies.


    In this regard, the effect of biological transmission is estimated to be better than that of droplet transmission. You have to consider the mobility of the population. Unlike modern society, many ordinary people may not travel far once in their life. If droplets spread, the virus may be limited to one city and cannot spread. Of course, if you don''t mind the trouble, you can also go to each city in person. "


    Yak nodded when he heard the speech: "it makes sense. The traffic here is really inconvenient. Obviously, the soul guide has been so developed that even the soul guide car has not been invented. Just because the soul master can fly and run faster than the car, he doesn''t invent the car. It''s really difficult for me to understand their brain circuit."


    The photographer shrugged: "I also want to know what they think. All terrain soul guides with eight legs that can run like spiders can be invented. So far, there is no soul guide car that can be popularized to the public.


    It can only be said that ordinary people are not as good as grass mustard for soul masters. No one cares whether their travel and life are convenient. The only meaning of their existence is to serve the old masters comfortably. "


    When I think of the original work, the sun moon Empire all terrain soul guide has been finished. The home soul guide car is just beginning to appear. It feels outrageous. You know, the real world has not produced a manned armored car with eight legs that can easily pass through all terrain so far. This is still the case when military science and technology has been higher than civilian science and technology for many years.


    "Considering the problem of population circulation, I have to make these viruses survive in plants, preferably the food that migratory birds like to eat. Um... Not necessarily plants, but insects, so we should consider whether these viruses can survive in the esophagus of birds for a long time, and then spread all over the world by relying on bird feces." Yak changed his mind and redistributed the variation direction of the virus.


    Obviously, such variation is absolutely effective in a world where people don''t pay attention to hygiene, people don''t even know how to boil the water before drinking, and they basically don''t wash their hands before eating.


    The virus spread faster than the two people thought, and the people here didn''t even have the slightest sense of prevention. Especially when people realize that this plague will only make people uncomfortable for two days, even if they are more determined, they can continue to work. No one cares. Anyway, they won''t be infected again once. Everyone even regards this disease as a disease that must be changed once, just like chickenpox and gills.


    Shrek college, Cheng Ying and Liu Tianxin looked at the sampling statistics passed back before. They exclaimed with egg pain in their expression: "there is a long way to go to revitalize the human civilization in this world."


    Liu Tianxin nodded: "I thought I had the greatest malice towards the poor living environment at the bottom of the society, but in these days, more than 90% of the people were infected. It''s still a little too outrageous. I''m afraid there are many districts on the mainland. There are a lot of shantytowns! Why haven''t I seen them in Shrek city?"


    The photographer rolled his eyes: "of course you haven''t seen it. As a miracle city on the continent, Shrek can''t allow the emergence of shantytowns? The civilians here. If they can''t prove that their heritage exceeds 500 gold soul coins, they won''t even enter the city.


    Do you know what the slogan of this city is? I recently noticed the slogan they put on the wall to build a noble city. This is the first time I''ve seen such a coquettish operation, driving all the poor out of the city, so the rest are aristocrats. How clever! "


    Yak''s eyes showed a little edge: "this situation will not last long. They will bring back the poor people who have been driven out one by one.


    They need factories, more labor, and more people to gather in the city. What they don''t know is that their behavior is weaving a noose for themselves! "
