Imperial Palace, Li Fu held a piece of data, his face always condensed a serious look, judging from the data obtained here from the various external space-time current passages, the situation is not too optimistic, because some people who have been boarded have been found more or less, and the situation is more serious than imagined.

But fortunately, the empire knew about this in advance, if it weren't for Li Jinghui's major discovery, maybe the empire would have been infiltrated by parasites now, and with the strong diffusion ability of parasites, maybe the entire empire would fall soon.

"They were all found at the mouth of the space-time current channel leading to the center of the Calavi Realm, and a total of more than 1,000 people were found in 5 ports, and all of them were caravans of the Fuyun Group, spaceships specializing in long-distance space trade, depending on the situation, they should all be parasitized in the river system near the Blood Moon Empire, and the situation is not too bad."

Li Fu made a simple analysis of the data, as the empire closed the country, the various caravans outside the empire also began to be urgently recalled, and no one who was lodged was found in the business and trade near the empire, but the caravan that was engaged in the far universe trade found the person who was lodged.

"Inform me to inspect the caravans that return later, especially those who return from the river system outside the Honor Alliance."

Li Fu thought about it and gave another order, at this time, be careful, be careful, be careful.

"Brother Fu, the Honor Alliance has contacted us here to protest against our unilateral blockade of the space-time current channel for no reason."

Li Fu's side, Yu Liang, Chen Bin, Cao Haitao and other elders also arrived at this time.

"Hmph~ Let them protest, I don't know if they're all dying."

"Our empire has not signed any trade agreements with them, and if you want to blockade it, you can do anything about it."

Yu Liang snorted dissatisfiedly.

"The Blood Moon Empire has also contacted us through the Honor Alliance, hoping that we can join the team against the Zelkan Alliance with them, and now these parasites control more and more river systems, like a tumbling snowball."

"Now we can't believe in anyone except ourselves, these river civilizations and forces may have been almost controlled by these parasites, and the ghosts dare to join them."

Cao Haitao and Yu Liang discussed with each other, and the others kept thinking about the empire's coping strategies.

"Shall we tell them about these parasites?"

"Tell them what to do? Let these zergs know in advance? Now it's these bugs in the light and we're in the dark, and once we inform them, these bugs will surely know soon, and then we'll be exposed. ”

"Unless we can work out an effective way to deal with them, and then we can really declare war on these bugs, it's better to drag it out for now."

Li Fu has never said anything, listening to everyone's discussion and discussion, what makes Li Fu unconfident now is that he is very afraid that these insects will infiltrate the empire and cause large-scale harm to the ordinary people of the empire, and he is not very worried about anything else.

"Let's go, go to the Imperial Academy of Biological Sciences."

Li Fu thought about it, there was really nothing good to do, and he was going to see the progress of the research on these insects by the Institute of Biological Scientists.

……

A secret research base of the Imperial Institute of Biological Sciences, a huge space city here, the entire huge space city has been tightly guarded, and there are imperial space warships guarding and supervising it at all times, once there is an uncontrollable situation here in the space city, the entire space city will be destroyed immediately.

In the space city, no matter which direction there is an imperial immortal-level Yuan Force master, there are a large number of advanced Yuan Force monks of the empire who are constantly checking here at the Dao Dao level.

At the core of Space City, the elite biological scientists of the empire are busy, because they are worried about being controlled by insects, so the scientists who have been transferred are all people with deep cultivation of Yuan Li, and Yan Jia, Li Shumad, Jiang Xianhe and other top biological scientists of the empire have also been dispatched.

At this time, Li Shumad was accompanying Li Fu, Yu Liang, Chen Bin and others to inspect.

"At present, our progress is very fast, because there are living samples, coupled with the preliminary research results of Gu Yun's side, our main thing at present is to conduct research in three aspects."

"One is to study how strong the parasitic ability of these insects is, and what kind of people can resist their hosting."

"The other is to develop an immunization vaccine that allows ordinary people to be immune to worm parasites."

"The last thing is to research a genetically targeted demon virus, a demon virus that specifically targets parasites, so that we can gain more advantages in the future war with these bugs."

Li Shufang took everyone to visit and introduced it in detail.

Everyone came to a laboratory, and there were people from the empire imprisoned in each laboratory, all of whom were people who volunteered to participate in the experiment, including immortal-level Yuan Force masters, and people with relatively shallow cultivation, all of whom had all stages of Yuan Force cultivation.

"Ah~"

"Woo~"

Voices came from the laboratory, and the citizens of the empire with little cultivation were easily parasitized by the parasites with little resistance, their eyes turned scarlet, and there were ugly cries in their voices.

As for those who are at the average level, they are constantly fighting with parasites for control of their bodies, their bodies are spasming and twisting for a while, and at the same time making painful sounds, some are able to resist, using Yuan Force to force out the insects that have invaded the body, and some are scarlet and demonic after failure.

As for the advanced Yuan Force cultivators, they are basically fine, even if they are invaded into their bodies, they can easily force these insects out with their strong and profound Yuan Force, which is rarely easy.

"We have recruited more than 10,000 volunteers, men, women and children, people of all stages of cultivation, we found that the higher the Yuanli cultivation, the stronger the resistance to this insect, and the cultivation above the Yuanshi level does not have to worry at all, but it is difficult to resist the erosion of this parasitic creature below the Yuanshi level."

Li Shuyan looked at the painful report in the laboratory, and sighed, there is no way, if you don't conduct an experiment, you will never know the ability of the bug, so some sacrifices are necessary.

"Is there no way to save the people who are being boarded?"

"It can't be helped, it's all the brain that is destroyed, and the brain is the most vulnerable place in our human body, and it is also the most mysterious place."

"You can arrange some masters to go over, and if you can't resist it, you can immediately help force the bugs out and reduce some deaths."

"Well, the experimental data is almost mastered, and there is no need to sacrifice anymore."

Li Fu looked at the painful faces, and also looked sad, these volunteers are the most courageous people in the empire to pay and sacrifice, many of them are scientists of the Academy of Sciences, and now for the sake of science, many people have sacrificed themselves without hesitation, which makes Li Fu very sad, but he also knows that this is a necessary sacrifice.

"This is our immunization vaccine research center, and we are studying the characteristics of this parasite, trying to find their weaknesses and study the corresponding vaccines."

Soon, everyone came to the Vaccine Immunization Research Center again, and everyone must be familiar with vaccines, in fact, the principle of vaccines is very simple, generally speaking, they can be roughly divided into two types.

One is to remove the replication genes in the corresponding virus genes, that is, the reproductive genes, and then transplant these viruses into the human body, so that the human body can produce corresponding antibodies, because these viruses have no reproductive ability, so they will not reproduce indefinitely and cause harm to the human body.

This kind of vaccine is more representative is the hepatitis B virus vaccine, hepatitis B virus vaccine is a kind of core RNA that removes virus replication, so that the virus can not replicate, only retains the shell of the virus, this shell is the antigen, when this non-toxic and non-replicating virus shell is inoculated into the human body, it will stimulate the body's immune system, produce specific immune factors against the virus, and retain immune memory, when the real hepatitis B virus invades the human body, The body immediately mobilizes the body's original immune mechanism to kill the invading hepatitis B virus and protect the body.

The other is to use bacteria and viruses that have already died. They are no longer disease-causing but they are still covered with shells, those characteristic protein shells, which are enough for macrophages to put on these coats when they are engulfed, and then they are reprocessed by helper T cells to release a large number of antibodies to gain immunity.

The simple way to put the two principles is to make the virus think that this life form has been occupied by its own kind, so it will not continue to occupy this life form again, after all, it seems that they are all a family, and naturally there will be no more harm.

"There is something special about parasites, they are not viruses, they are much bigger than viruses, we use dead parasites to make vaccines, but all of them fail, they seem to know each other's existence or not, and this has not been very smooth."

Li Shufang took Li Fu to visit here, and shook his head again and again about the research progress of immune virus vaccines, parasites and viruses are not the same thing after all, and it is useless to study the methods of virus immunization vaccines to deal with parasites.

"I remember that Li Jinghui's report mentioned one thing, these parasites seem to be hierarchical, can we start to study immunization vaccines from this aspect?"

Li Fu has been listening, in fact, he is very concerned with the research of immunization vaccines, because only the research of immunization vaccines can ensure the safety of ordinary people in the empire.
