No matter which of the two parallel time and space it is, under normal circumstances, in order to prevent the genetic mutation caused by cosmic radiation from bringing microbial catastrophe to humans, all the operators who go out to fight will turn on the laser sterilization device on the surface of the mecha when the battle is over and their own conditions allow, so as to remove all kinds of bacteria or viruses on the surface of the mecha that are brought out of the hull by the mecha to the greatest extent, so as to prevent the microscopic life forms that may have mutated from being brought back to the inside of the hull.

However, in World A, the lymph node hemorrhagic fever virus, which was originally just a virus that has long been known to mankind and lives inside the Hope, with a very low lethality rate, was brought back to the hull of the ship after being taken to the high-radiation space by a certain soldier of the resource mining team due to various coincidences.

By the time the Resource Exploitation Team brought back the Hope, it had evolved and mutated into a new type of virus that was completely unknown to humans, and soon rewrote the history of human medicine, and eventually was engraved in the history books along with many notorious viruses such as smallpox virus and Ebola virus because of its high infection rate and high fatality rate.

"According to you, when lymph node hemorrhagic fever spread on your spaceship more than ten years ago, due to the large number of sick people, you were very lucky to find a patient who recovered on his own after the disease, and relied on his blood to make antiviral serum, and then made many patients, including you, all better, right?"

"Yes, that's it." In the bright and tidy medical room, Ping An, who had told Shu Lang about her personal experience, soon learned from him some facts that happened in this time and space that she could never have imagined.

Birth, old age, sickness and death, these are the four states that most living things, including plants and animals, will experience in their life journey. Therefore, as an alien creature, adventitious insects also have these four life states, which is not surprising in the eyes of humans.

Once upon a time, scientists from the Institute of Extraterrestrial Biology once proposed that "it is possible to use some kind of chemical or biological weapons to kill adventitious insects in the same way as killing and injuring humans, so that they can be poisoned to death or break out a wide range of infectious diseases, so as to greatly reduce the difficulty of human warfare against adventitious insects", but it is a pity that this idea was ultimately proved impossible in the A world where Ping An lives.

Whether it is the erosive poison mustard gas, the irritating poison Adam's gas, or the nerve agent sarin gas, the six types of chemical poisons produced by human beings, as well as chemical agents such as leaf blight, which are specifically aimed at plants, even if they are ingested into the real body by adventitious insects, none of them can effectively kill them. Biological weapons that use a variety of bacteria or viruses have similarly failed to achieve any noticeable results.

Scientists from the Institute of Extraterrestrial Biology have found through research that whether it is the true body of the adventitious worm or its external cells, these substances that are completely highly toxic to humans and will cause immediate death of humans once they enter the human body through the digestive system, can well absorb or dissolve the chemical agents invented by human beings, and directly kill all kinds of microorganisms.

Therefore, whether it is on the surface or in the body, the adventitious worm, which has basically been in a state of no bacteria and no viruses, has long been defined as a terrible creature that does not get sick, even if they try their best to make it sick, but it is never available.

Whether in World A or World B, under normal circumstances, in order to prevent human poisoning caused by adventitious insects' body tissues, all operators who manipulate humanoid mechs to attack must wait for the mecha to complete cleaning after the pollution level on the surface of the mecha reaches the orange level, and then they can walk out of the control cabin. It's just that there are always exceptions

A few days before Ping An and Dior crossed the wall of time and space, the Hope of World B encountered a "sick" adventitious insect for the first time in history.

The many large yellow-red blisters growing on the surface of a certain adventitious insect that were supposed to have a uniform and smooth texture caused a huge sensation in the vast majority of the combat crew and all the staff in the alien biological research institute the moment they were observed by the commanders and fighters on the Hope.

"The history of indefinite insects not getting sick has been rewritten! This adventitious worm is definitely a valuable research material for us to encounter, and we will do everything possible to use it as a research sample and bring it back to Hope. ”

The operators of the USS Hope's Mothership Escort Team, who didn't need instructions from their superiors at all, did indeed use this adventitious worm as a research sample, put it in a sample bottle, and brought it back to the mothership after a hard battle. However, in the course of the battle, one soldier was seriously wounded and his life hung by a thread.

"In the face of life, everything must be compromised", it is precisely because of this belief that this operator, who was carried out of the control cabin without going through the mecha cleaning process at all, finally became the first person infected with lymph node hemorrhagic fever.

The doctors and nurses who entered the operating room with him, as well as the comrades-in-arms who escorted him to the hospital, all became infected, and even inadvertently transmitted lymph node hemorrhagic fever to other people, and eventually led to the emergence of lymph node hemorrhagic fever virus carriers in the living area, whose body is still in the incubation period.

"Not from a genetic mutation, but from a sick adventitious worm that the Mothership Hope encountered by chance before Dior and I were rescued as survivors of the third spaceship?"

Because the outbreak of lymph node hemorrhagic fever that I had experienced was an occasional sudden situation caused by a coincidental genetic mutation, so, like everyone I knew at the beginning, I never thought that this virus could make adventitious worms sick, and I was so sick that I was safe, and now I listened carefully to Shu Lang's story, and I only felt that my jaw was so surprised that I couldn't close it.

"When we get back to the mothership, I'll have to submit an application to go to the Institute of Extraterrestrial Biology to see the adventitious worm that has been used as a research sample and has died."
