Enter the Immortal Cultivation

Tiange Wuxiang Sword Qi is a magical power developed for "secret plots". Although the fluctuations of sword energy are difficult to conceal, the visual "invisibility" also makes it a bit confusing. It can use the principles of far infrared rays to far ultraviolet rays to kill people with invisible sword light.

However, when the Immortal Alliance discovered that there were many species in the world whose visible light bands were completely different from those of humans, they lowered the rating of this spell a lot, and the ANBU Third Division strongly discouraged this spell.

However, there are other times when this spell can be useful.

For example, disinfection.

Starship magic weapons, as well as any items in other biospheres on the starship, must be bombarded by this sword energy when entering another biosphere [including but not limited to the biosphere of Shenzhou Houtu]. Among them, if a starship wants to enter the atmosphere, it needs to be exposed to phaseless sword energy or similar spells for up to five hours.

Now, Song Shufu obviously wanted to use this spell to do something.

An invisible and formless sword energy slashed out, passing over the tube of solution.

Then, call it a day.

"Because the smallest frequency band that I can buy with the highest accuracy is far inferior to what I can control myself, I will complete this step myself - and it will be faster." Song Shufu said: "This That’s its most terrifying characteristic—it’s difficult to kill even with ultraviolet radiation.”

Chen Feng was stunned.

Not because I was surprised, but because...

This looks so familiar.

Citrine plague is also extremely resistant to ultraviolet rays...

The principle of ultraviolet inactivation is to excite free radicals - that is, to transfer energy through light, causing the covalent bonds in biological substances to cleave unevenly, producing groups with unpaired electrons.

In other words, ultraviolet rays are very damaging to substances with covalent bonds. Covalent bonds such as carbon-hydrogen and carbon-oxygen are the most common types in living beings.

Of course, due to different structures, different living creatures also have different resistance to ultraviolet rays.

However, nucleic acid, the substance that burns blood connections, is extremely sensitive to ultraviolet light.

Therefore, it is not uncommon for ultraviolet rays to cause cancer or even lead to mental mutations.

Tianling Palace originally thought that the real resistance to ultraviolet rays was the Alu'er fairy power attached to the yellow crystal plague poison. But what if this ability comes with the Citrine pathogen?

For example, the shell structure of the living creature's source material is special...

"I locked on a special band of ultraviolet rays, which are more easily absorbed by bloodline roots." Song Shufu said: "According to common sense, there shouldn't be any active pathogens in this band, but!"

"It can still cause disease."

Chen Feng was extremely surprised. He almost wanted to shout "impossible".

And Song Shufu had already gone out to bring the living creatures.

Three tubes of liquid were slowly injected into the three sleeping horses.

Chen Feng felt as if his mind was a mess.

He looked at Song Shufu and said, "Senior Brother Song, this... what do you think?"

"How do you see it? How else can you see it." Song Shufu shook his head: "An extremely terrifying pathogen - of course, it is only difficult to kill and find. It is basically harmless to monks."

"I mean..." Chen Feng said, "Have you analyzed why this is happening?"

"Well, I have some conjectures." Song Shufu pulled up a stool and sat down, then threw another one to Chen Feng, gesturing for him to sit down too: "I suspect that I have found a brand new type of pathogen."

The words were trembling. There was unconcealable excitement in his tone.

This must be an achievement that will be recorded in the annals of celebrities.

A new type of pathogen discovered!

Just like defining "germs" and "viruses"!

Chen Feng nodded. He thought of Huang Jing again.

If ultraviolet resistance is an ability inherent in the inherent structure of new pathogens, then...

"First of all, what is certain is that it is definitely not a parasitic disease, because my spiritual consciousness cannot find any parasites or parasite eggs." Song Shu replied: "Perhaps some demonic insects can produce eggs that are hidden from the monks' spiritual consciousness. However, that kind of parasite cannot be harmless to monks, let alone, it is difficult for people to be infected. "

Chen Feng nodded in agreement.

"Then, it cannot be a plague virus in the general sense, because the plague virus cannot produce enzymes and cannot complete most of the physiological activities necessary for survival - it must be parasitic in a living body to survive." Song Shufushen He took out his finger and flicked the specimen jar he just took out: "And this piece of rotten meat cannot contain Mars - even a living cell. Therefore, it must have an independent enzyme system that can complete physiological activities. of."

Even in a dormant state, active creatures will slowly change - otherwise, they will die.

"But at the same time, it cannot be a plague. Because it is impossible for a plague to withstand the ultraviolet rays just now." Song Shufu then asserted: "Unless there are some special organelles that can convert the bloodline's original appearance [chromosome] into a The structure is wrapped and must be thick enough, otherwise, if there is any gap, ultraviolet rays can penetrate. ”

"Even endospores of certain plague fungi are not possible."

Endospores, also known as spores, are dormant bodies that some bacteria spontaneously form inside cells under harsh conditions. Spores have lower water content than the cells themselves, and their membranes are more numerous, thicker, and denser.

"But the plague virus cannot spontaneously complete any physiological activities, and the plague bacteria are too large to protect themselves. Then, this pathogen must be smaller than the plague bacteria, but larger than the plague virus. At the same time, it has a thicker outer shell of life source material, which can resist ultraviolet rays."

Chen Feng pondered: "You mean... Rickettsia [Rickettsia. According to a certain correspondence method, in this world, it was discovered and named by a person named Li] or Chlamydia? No, these two pathogens are just smaller than the plague bacteria and larger than the plague virus, but not enough to resist ultraviolet rays."

Li Ci and Chlamydia are both new fields that have been developed in the last few hundred years. However, there are not as many research objects in these two fields as plague bacteria and plague viruses. Among them, Li Ci was named to honor the sacrifice of a plague god named Lin Xiushi during the research process.

Neither of these two pathogens has all the properties of "bacteria". They have complete and independent cell membranes, independent enzyme systems, and independent genetic material, but they lack enzymes that synthesize high-energy substances. This requires them to parasitize inside cells in order to reproduce. But on the contrary, if the high-energy substances obtained are scarce, they may also be dormant - but they are only more resistant than viruses.

It is definitely not to the point where "a piece cut from the specimen is still pathogenic."

Song Shufu interrupted: "So, it's a new type! A new type! Absolutely, it is definitely an unknown type!"

"Smaller than the plague bacteria, larger than the plague toxin...?" Chen Feng repeated this sentence again and again, and then asked: "Brother, have you used a filter or filter membrane to verify the size of this plague toxin?"

Song Shufu's face sank, and he said: "Huh... I have used it, but I can't get a finer filter membrane, so I can only prove... After all cells are filtered, the pathogen of the corpse horse plague can still exist in the solution."

Chen Feng suddenly realized.

The senior brother who fainted in Tianling Palace not long ago was indeed an extraordinary person.

Although the students of the Immortal Academy can think of the method of constantly adjusting the density of the filter to continuously approach the volume boundary of a very small object, ordinary cultivators really can't use it. How many filters with different rules are needed? If all of these need to be customized, how much time will it take?

Not to mention, the ultra-fine filter or filter membrane itself is already very expensive.

For a cultivator like Song Shufu who is restricted in every way, using a filter membrane to determine the upper limit of the volume of the corpse horse plague pathogen is already the limit.

Cultivation and funding both limit a cultivator's research capabilities.

Thinking of this, another data appeared in front of Chen Feng again.

The minimum cross-sectional diameter of the yellow crystal pathogen is ten nanometers.

Ten nanometers, this is already far smaller than the general plague, and it is impossible to be a pathogen that is "larger than the plague and smaller than the plague bacteria".

Do the corpse horse plague and yellow crystal really have similar structures?

Or...

Song Shufu continued: "A few years ago, I applied for a sum of money from the Guanghua Hall of the Guiyi League because the protective layer of the corpse horse plague was unexpectedly resistant to ultraviolet rays - but the Guanghua Hall was not very interested in this. For them, there are as many spells as they want to resist harmful electromagnetic radiation. If it weren't for the possibility that this plague could extract an unprecedented structure and contain unknown principles, perhaps I wouldn't even get that sum of money. It was also because of this application that I got a batch of better instruments from the Guanghua Hall, and I also practiced the Tiange Line by asking the monks there for advice."

"It's a pity that there was no research result until the funds were spent, so the Guanghua Hall didn't add the second sum of money."

Song Shufu's tone was not without regret.

This is no wonder. No matter how rich the resources controlled by the Shenzhou human race are, the total amount is limited. This must be able to increase investment in key areas.

And the "possibility" provided by Song Shufu is not worth investing in for the Guanghua Hall. It is already the limit to be able to attract a sum of funds.

But...

Is it really like this?

——The minimum cross-sectional diameter of the yellow crystal pathogen is ten nanometers.

Can such a small scale really form a structure that can resist ultraviolet rays?

Or is the yellow crystal plague and the corpse horse plague not the same thing at all?

Chen Feng said: "Brother Song, is there any public empirical record?"

"Yes, there is." Song Shufu stared at Chen Feng and said: "But then again, how much funding do you have for your project? I know that confidential projects are generally very... rich, right?"
