In history, several severe pestilences occurred in the western continent, killing and injuring hundreds of millions of people each time. Of course, most of the dead are ordinary people, and the proportion of professionals is less. Especially for the high-level professionals, either the physical organs are elemental or the mental strength is substantial. They have reached the extraordinary level and have natural immunity to diseases.


    As for the legend, it has not been heard that people died of infectious diseases.


    The mainland has also summed up the experience of solving the plague. The first is to control the population flow and isolate the source. The second is to analyze the causes of the epidemic, and then formulate the corresponding drugs.


    It is easy to kill the toxins or microorganisms that cause the disease, but the difficulty lies in that they can not cause irreparable damage to the human body at the same time.


    As far as Yan Chong knows, in the modern world, there are a lot of diseases that have not been completely developed virus vaccines, so they can only be eliminated by the time.


    Most of the survivors who were successfully cured were stimulated by instruments and drugs to overdraw their immunity to resist the disease. After being cured, they also left serious sequelae.


    Although there is no high-tech like that on earth, high-level professionals are either majestic in life or spirited in spirit, so they can still sense the root cause of the plague.


    According to the research conducted by a large number of pharmacists gathered by the association in recent days, the plague is a mixture of toxins and microorganisms, with a variety of no less than dozens, so it is extremely difficult. What they have in common is that they all have a large number of dark group elements.


    Obviously, everyone thinks that the plague and the devil are inseparable.


    Yan Chong also saw the introduction of demons. There is a kind of devil called pestilence. Compared with the same level, the combat effectiveness is not high, which can be said to be the bottom, but it can spread the plague. It can be said that it is a weapon of war.


    If it is the plague spread by the legendary pestilence devil, not to mention the high-level professionals, even the legendary professionals may be hit.


    If you get the plague, you may not die. You can even cure it by your strong vitality. However, your strength will be greatly reduced and most of your combat effectiveness will be lost.


    Originally, the Mainland generally believed that the plague was spread from hell, and this demon invasion confirmed this point.


    There are a small number of pharmacists who specialize in poisons, known as poison pharmacists, but the poisons they develop are not as good as the plague.


    Most of the poisons will be diluted, so only a limited number of people can be killed. But the plague is different. As long as the number of people is enough, a little bit of the source can spread infinitely.


    But every time a plague occurs, these poisoners become the main force, because they are familiar with this aspect.


    The medicine for curing plague also needs to meet two functions: one is to cure the human body and stimulate its own immune capacity; the other is to kill the epidemic disease, which is also a kind of poison in essence.


    Even in killing the epidemic disease, it will kill the human body without any difference.


    After reading these materials, Yan Chong had a general understanding of the plague, because he had the ability of an S-level pharmacist and had a lot of knowledge in his mind. Once he saw the professional terms, he could trigger his memory and deeply understand it.


    Yan Chong directly asked for a laboratory and a pharmacy master''s badge in the association, so that he could be unimpeded in the city of glory Pharmacists Association.


    Resources below the extraordinary level are completely free to him, while the resources of extraordinary level and rare level will only be charged according to the cost price.


    If he really agreed to the invitation of those pharmaceutical masters, he would not only be a nominal person, but also get a certain amount of free resources.


    The whole body was protected by vigorous Qi. Yan Chong directly took a piece of blackened human tissue, which was the body of an ordinary person who died of an epidemic disease.


    Not affected by nausea, Yan Chong directly turned on the element vision and looked at this human body tissue.


    The angle of view is constantly adjusted until we see the cell level, which is not the limit. If we continue to zoom in, we can even see the DNA and RNA structures in the nucleus.


    Generally speaking, only when the spirit reaches the legendary level can we observe the tiny things at this level.


    With the naked eye, even legends with epic physique may not be able to do so.


    After just one attempt, Yan Chong was surprised to find that his eyes were so rebellious that they could be used as high-precision microscopes without the aid of special alchemy instruments.


    This study is undoubtedly more convenient and free.


    ……


    At night, Yan Chong left the laboratory and returned to the residence specially provided by the Association for pharmacy masters after dinner.


    With his current strength, it''s no problem to study it for a month, but he still has more important things to do.


    It''s that the consciousness of the book of prophecy is finally fused.


    As for the study of plague, Yan Chong found that it was very difficult for him to study it in a short time.


    There are a variety of virus structures that cause the plague, and some bacteria are in it. They coexist perfectly. Viruses do not destroy the structure of bacteria, only human cells.Moreover, they all contain a large number of dark group elements, which can be constantly mutated.


    Yan Chong suspects that there may have been only one kind of virus and one kind of bacteria at the beginning. These viruses and bacteria have no harm to human body and are benign and have always existed on the mainland.


    However, after exposure to different kinds of dark group elements, they have a variety of variation, causing a variety of symptoms on the human body, the situation is extremely complex.


    If it were not for the fact that people on the endless continent are generally of high physical quality, and there are elements of heaven and earth everywhere, which nourish the human body imperceptibly, this plague is likely to be a hundred times more serious than the current situation.


    In addition to the four basic elements, each of the other special elements can be neutralized with a dark group element, so the severity of the plague is not as serious as expected.


    But as long as after a period of time, the plague mutates in a chain nature, adding thousands of variants, then things are completely out of control.


    These dark group elements could not exist in large quantities in the endless continent, and most of them were neutralized. However, they changed the viruses and bacteria, and then hidden them in the viruses and bacteria, so that they could survive and spread in large quantities.


    It''s chilling to think about it. When the endless continent is filled with dark elements, it will be transformed into a paradise for demons.


    By the way, Yan Chong suddenly thought that no matter how strong a professional is, it is impossible to blockade the whole continent even if it is not at the level of gods. But what if the mainland is full of dark clan elements?


    The plague of the East became another hellish influence, wasn''t it?
