Enter the Immortal Cultivation

The first step in studying a particular plague is either to try to isolate the pathogen and culture it separately, or to conduct a pathological analysis.

Isolating pathogens is both difficult and easy.

Like many demonstrations of the Way of Life, this is also a process of looking at the face.

Injecting substances that may contain pathogens into a suitable environment, after which tiny creatures that may be pathogens will increase on their own.

Of course, the cultivation of bacteria and parasites is the simplest. Their culture medium only needs to include inanimate agents containing nutrients. This is not the case for more tiny creatures.

Pathogens such as viruses and chlamydia lack the ability to synthesize enzymes and cannot complete many reactions necessary for life. They need to survive in living things.

Animal embryos are a very good choice - because compared to adults, embryos are easier to culture and it is not difficult to produce any messy antibodies.

The factor of "fewer antibodies" is the reason why fetal bovine serum is better than newborn calf serum, and newborn calf serum is better than calf serum.

Of course, a calf weighs many times more than a fetus, and can extract more serum than a fetus. In addition, the manufacturing environment of fetal bovine serum is more demanding, so in terms of price, fetal bovine serum is more expensive.

This is also the reason why scientists on Earth use eggs to study vaccines - eggs are also embryos, chicken embryos.

It can even be said that in the 21st century, the vaccine industry on Earth is also a major consumer of eggs.

The principle of the vaccine is to inject inactivated or attenuated pathogens into the human body, and the pathogens must also be cultivated.

The main influenza vaccine manufacturers on the planet are still mainly chicken embryos.

The reason is simple, cheap.

The cost of raising chickens is much lower than that of cattle. The price difference between chicken and beef is a very real reflection of this.

What is even more valuable is that chickens, as poultry, have an advantage that mammals cannot achieve - each egg is equivalent to a closed sterile bioreactor. If eggs are chosen, even the requirements for the production environment can be reduced.

Of course, eggs as a culture medium for producing vaccines are not omnipotent. First of all, if the outbreak is a disease such as avian influenza that is more lethal to poultry, then don't cultivate it. The embryo in the egg will be killed by the pathogen before the cultivation is completed.

In addition, if a large-scale outbreak suddenly occurs, the production of the vaccine is doomed to fail to keep up - after all, it is still positively correlated with the poultry farming industry.

In addition, people who are allergic to eggs will be a little unlucky.

Therefore, most pharmaceutical companies on Earth are studying related technologies for bacterial cultivation. However, at least in the early days of the 21st century, there is no mature technology.

Of course, Shenzhou does not need this technology. Most diseases can be treated with magic to increase vitality and keep people alive, and then drag them until the human body produces antigens or immune cells with non-specific anti-infection functions kill all pathogens.

Of course, immune diseases generated by overreaction of the immune system and secondary immunodeficiency diseases have another set of treatments.

By the way, among secondary immunodeficiency diseases, the famous acquired immunodeficiency syndrome... has not been found in Shenzhou.

However, as of now, this method is still difficult to use.

This batch of yellow crystal samples was collected by Wang Qi at the beginning. At that time, the exiled fairy Aluer was still sleeping, and the controller on the surface of the yellow crystal land was the unknown Loud Zerg. The Loud Zerg, known as the "Yellow Crystal Demon", did not have much understanding of the essence of the Yellow Crystal Law, but could only simply control and infect.

This batch of yellow crystal samples is aimed at the creatures in the same biosphere as the Yuan Clan.

That is, because Loud Star once belonged to the Yuan Clan, the creatures on Loud Star have a direct connection with the Yuan Clan's mother planet. Otherwise, if it were another planet, the "Yellow Crystal Demon" would not appear at all.

This batch of yellow crystal cannot infect the creatures of Yuanlong Star - whether it is human, mammals, or birds.

Unless Tianlingling is willing to risk the entire generation of Shenzhou's breeding industry, collect all the eggs in Shenzhou, and then bet that there is even one pathogen in this batch of yellow crystals that mutates and has the ability to infect the creatures of Yuanlong Star.

So the question is - where can we find creatures that can definitely cultivate the Huangjing pathogen?

When the troops of the Zhengtian Division arrived, apart from the Laod Zerg, there were only seaweed black anaerobic bacteria on Loud Star.

If the Laod eggs are used as culture medium, the Laod clan may rise up in rebellion, and the sea gods may also be disloyal. The reactions of the demon clan and the dragon clan cannot be ignored.

Moreover, there will be many people in the Immortal Alliance who can't stand it.

The remaining options are only the existing seaweed and anaerobic bacteria, or the living tissue of Loud extracted from the Laod samples brought back to Shenzhou and expressed by the shapeshifting method.

However, whether it is the Laod Zerg or the Laod seaweed, their ecology, genetics, biological properties and other factors, the human race really does not understand any of them.

Who knows which components are pathogens, which components are their original, or by-products of the physiological activities of pathogens.

No one stipulates that Huangjing must be the main body of Huangjing pathogens - it may also be a metabolite of Huangjing pathogens?

Then there is only pathological analysis.

"I remember it correctly... This link should be combined with the medical history for pathological and histological examination..." A Tianlingling Yuanshen monk looked at the sample in front of him and showed a frustrated expression: "We also don't understand the physiology of these bugs - I heard that they also have incomprehensible behaviors such as traumatic insemination.”

"Regarding this, colleagues from the same sect have already gone to investigate the planet that the Loud Zerg went to."

Another disciple stretched his neck over and whispered: "It's impossible for these guys to completely understand their own bodies, nor do they have no medical skills."

"Microbiome is also studying some anaerobic bacteria and algae." Another person said: "We mainly conduct histological research."

According to the reactions of Zheng Angel who came into contact with Huang Jing, Huang Jing's infection mostly starts from the nervous system. Therefore, apart from Jiyin Valley, the most common place here is Yangshen Pavilion. More than half of the Yangshen Pavilion monks are also familiar with histological research.

Chenfeng skillfully took out a few seaweed samples and performed the initial fixation.

The so-called "fixation" is the standard starting point for pathological research. After pathological samples are separated from the body or dead, autolysis and decay will occur due to changes in the microenvironment, and their structures are easily destroyed. "Fixation" means to keep the pathological specimens in their original state as much as possible.

First, it means using the magic of thermodynamics to lower the temperature. This is mainly to coagulate the source of life and reduce or stop the action of certain enzymes, so that cell autolysis is stopped and the antigen is not inactivated.

Most people who do research on the way of life know one or two thermodynamics spells. It is said that some monks who have done well in practice have even mastered one or two levels of Tian Entropy Art - some people in Tianling Ridge even think that one or two of the outer sects of Fentian Mansion might do better in this kind of work.

Then, use the magic of Burning Gold Valley to separate out the water.

This kind of spell is like the method of plundering atoms according to a specific ratio of the super-heaven, but the configuration is lower. A spell can only target one kind of physical property, and it is difficult to apply in a battle.

Next, it’s time to test your cultivation. In this step, researchers need to use soft and dark strength to pat fixatives such as paraffin into the sample without damaging the sample structure.

Of course, if you are not in a hurry, you can also let the paraffin seep in slowly. However, there is always the risk of spoiling the sample.

A monk like Xiang Chenfeng could only control his strength and tap slowly on a sample.

Of course, fixed observation is only part of it.

Anyone who has sufficient cultivation and has mastered any of the lower magical powers of the Flame of Fate can choose to use the Flame of Fate to suspend the life of the sample, and then observe it slowly.

But there is also the problem of pathogens overproliferating and changing the structure of the sample. It is said that a disciple of Tianlingling once observed a rather exaggerated scene - under the influence of the Flame of Fate, the overproduction of pathogens eventually did not cause the death of the sample but physically destroyed the structure of the sample.

That scene was very damaging to mental health.

Of course, both pathological observations need to be made.

However, this kind of direct observation is unlikely to yield results.

Huang Jing is actually Alu'er's martial body, and the power of Huang Jing is part of Alu'er's fairy power - the fairy power attached to these samples collected by Wang Qi is not enough to fully carry Alu'er's consciousness, and it is impossible. Realize the catastrophe.

But reflected at the "molecule" level, this group of spiritual power is amazing - it isolates many temptations.

This is natural encapsulation. Considering that the Yuan clan is no stranger to the plague spell, perhaps they will also deliberately strengthen this interference with vision and spiritual consciousness. But without this magical power, some of the unique structures of the citrine pathogen would not exist. If it were scattered, the pathogen would die and decompose instantly.

As you can imagine, there will be no mysterious gains on the first day.

After five days passed, Helix Shuangzun pretended to be relaxed and announced one thing at the gathering: "At least we can be sure that the pathogen is neither a germ nor a parasite."

This joke earned an awkward yet polite laugh.

Everyone knows it.

After all, the report given by Zhengtiansi clearly stated that the Topaz Plague can distort the cell structure of the infected person. No matter how you think about it, this doesn't seem to be caused by germs or parasites.

But... there is still a slight possibility - what if the metabolites of some kind of bacteria or parasites can achieve this effect?

Now, this possibility has been eliminated.

This is also very good! Isn't this an achievement?

"So, we have successfully taken a small step." After Chen Feng dragged his exhausted body back to Ai Qinglan's ward, he changed his words with his hometown accent and repeated to Ai Qinglan: "Your master Said.”

"At this time, you should say - it's too boring! Isn't there a more interesting way to play?"

"Well, of course, there are also more... ways to let yourself go."
