Enter the Immortal Cultivation

——Could it be that... the yellow crystal pathogen... doesn't have nucleic acid at all?

Once this thought came up, it was like a prairie fire, burning Chen Feng's spirit.

The minimum cross-sectional diameter of ten nanometers makes many things unexplainable.

For example, in such a narrow space, no matter how long it is, nucleic acid cannot complete folding.

However, if it doesn't have nucleic acid...

If its blood is not composed of nucleic acid substances...

That's right, that's right, Shenzhou has been prepared for a long time. When it knew about the existence of the immortal road, there was a theoretical hypothesis that not all blood spiritual resonance is recorded on the nucleic acid system.

However, so far, among all carbon-based creatures, no creatures beyond this range have been found.

The blood of all carbon-based creatures is recorded on nucleic acid substances.

The reason is very simple. The genetic material that records the blood spiritual resonance must be stable and not prone to physical changes, but it cannot be too stable, resulting in "evolution" not happening. At the same time, this substance needs to be able to replicate itself.

Indeed, in theory, there can be a system that carries the blood spiritual resonance by sugars, lipids or creature source substances, which is also an option.

However, these substances are either not stable enough, or too stable, or cannot form complex systems, or the systems are too complex.

In evolution, these systems will not have any advantages over nucleic acids.

Long before people with sugar substances as blood roots began to evolve, their ancestors were wiped out by the ancestors of today's human race - some primitive bacteria based on nucleic acids.

This is also the reason why the "transfiguration method" has a wide range of applications. One of the foundations of this method is the structure that can be provided by carbon atoms with four valence bonds, which is based on the folding method of this system.

The Yuan clan and the Loud Zerg are both carbon-based creatures. Like the human race and the dragon clan, which are creatures born from the Shenzhou Houtu, their blood roots are also nucleic acid substances.

The yellow crystal pathogen and the corpse horse plague originated from the mother planet of the Yuan clan and the Shenzhou Houtu respectively.

A planet is too small to accommodate two completely different blood systems.

It can even only accommodate creatures with the same chirality.

This is the so-called "convergent evolution".

The wings of hummingbirds and moths, the tail fins of fish and seals. Creatures that are not related may also have similar appearances due to the same external environment.

The underlying physical laws determine that in most cases, this bloodline system is more advantageous. Therefore, more extensive convergent evolution occurs in carbon-based creatures on different planets and in different worlds.

There should not be such creatures.

Chen Feng returned to the ground with such a heavy thought.

In Tianling Palace, "Practicing Yuanzu Gongfa" has become a new round of attempts.

They want to try to control the yellow crystal pathogen with magic.

Aluru's deeds have proved that there is some inexplicable connection between Yuanzu Gongfa and the yellow crystal plague. Aluru himself deduced his own method of asking the saints through the inheritance of the Yuanzu, and became the only anomaly.

Perhaps, they can also try to analyze the Yuanzu Gongfa.

At worst, they can rely on their understanding of the Yuanzu Gongfa to gradually break the remaining power of Aluru on the yellow crystal pathogen.

Only Chen Feng returned to Ai Qinglan's ward with that rebellious thought.

"Today, my thoughts are somewhat rebellious, Sister Lan." Chen Feng whispered: "If your uncle knew my thoughts, he might kick me out of the Evidence Department immediately? Haha... For a cultivator like me in the Jindan stage, it is really difficult to survive in the current Evidence Department!"

-But, if there is no nucleic acid...

The next day, he went to Song Shufu's Evidence Department again.

There was a pile of porridge bowls next to the desk. It seems that this person plans to clean it up every few days.

After not seeing each other for a few days, Song Shufu's dark circles have increased a lot, and the whole person looks lifeless. Chen Feng was shocked and said: "How did it become like this? I remember you said a few days ago that you found the witchcraft you wanted, right?"

Song Shufu nodded speechlessly.

In fact, it is really difficult to find a witchcraft that you don't even know the name of and only exists in legends among the vast number of ancient methods. Even with a catalog and search engine, you still need to have a broad, overall understanding of the "ancient methods", and then have a more detailed understanding of the field you want to find.

Not to mention modern practitioners, even ancient practitioners with extensive knowledge and strong memory may not be able to do it.

To be honest, in today's Shenzhou, it seems that only an old antique who has just been resurrected from ten thousand years ago can meet this requirement - it's just a pity that most people's understanding of this old antique is limited to the textbook "The death of this Mahayana monk and the rise of the Holy Infant Church marked the arrival of the 'Holy Infant Church Era'".

To be honest, this old man who slept in the ring for ten thousand years didn't want this kind of reputation at all.

Song Shufu searched for almost a month. God will not let down those who work hard, he did find three witchcraft spells that conform to the legend.

But...

"Failed." Song Shufu said: "After revising the witchcraft spell into a 'spell that interacts with pathogens', it is impossible to sense the corpse horse plague pathogen in the dwarf horse. It's as if they have never been infected."

-Ten nanometers.

——No nucleic acid.

A piece of data and an inspiration appear at the same time

But after thinking for a while, Chen Feng finally suppressed this idea. He couldn't say it directly.

It is also very likely that the corpse horse plague has a completely different structure from the yellow crystal plague, but the symptoms are similar.

Although they may also be the product of "convergence", it is only "possible".

Chen Feng whispered: "Brother Song, could it be... the pathogen of the corpse horse plague is smaller than you think?"

For different pathogens, the transformation of this "plague curse" and "sympathetic method" has many differences.

Song Shufu smiled bitterly: "How is it possible... How is it possible?"

"The corpse horse plague may also be a plague poison..."

-Or something smaller than this.

"How is it possible! What plague poison can withstand that kind of formless sword energy?"

Before Chen Feng finished speaking, Song Shufu suddenly exploded. He jumped up and roared.

Chen Feng immediately shut up.

After a while, Song Shufu pressed his forehead and whispered: "I'm sorry, I lost my mind and my cultivation is not enough..."

"It's just human nature." Chen Feng didn't care: "Brother, the next step..."

"I will gradually adjust the spell. In addition, I have also ordered new instruments with the funds you injected, and also made an appointment with the monks of the Guiyi League, who have a higher level of Tianyan Tulu cultivation. I will try to use more precise optical observations, and entrust the monks of the Guiyi League to test with more precise frequency bands."

After this, both Tianling Palace and Song Shufu fell into some strange quagmire and failed frequently.

Song Shufu's spell was changed more than ten times, but he never sensed any pathogens.

And in Tianling Palace, all the human cultivators who tried to practice the Yuan clan's skills failed.

Without exception.

The reason is unknown.

At the beginning, everyone thought that it was because the Yuan clan's skills were too profound. However, when each route of practice was analyzed, this statement was broken by itself - after all, it was a mental method from the Qi training stage to the foundation building stage. No matter how complicated it was, it could not be so complicated that even the Yuanshen stage cultivators could not do it.

Otherwise, how could the Yuan clan practice by themselves?

However, the reality showed that the human race could not practice the Yuan clan's method.

Some human cultivators tried to inject Yuan clan blood cells into their clones, or simply chimera Yuan clan tissues. The cultivators with advanced cultivation began to try to use the shapeshifting method to form the Yuan clan.

But the Yuan clan's practice method seemed to contain some kind of bad ridicule from 200 million years ago.

- Look, you inferior races can't crack our civilization achievements at all!

Including the method of transforming into the Yuan clan, there is no way for the human race to successfully practice the Yuan clan's practice method.

Even if it is only the Qi training part.

This point has indeed attracted widespread attention from the upper echelons of the Immortal Alliance. The shapeshifting method announced by the Dragon Clan is already the top method among the descendants of the Heavenly Favored Clan - otherwise, His Majesty the Dragon Emperor would not have been able to beat the leader of the Yuan Clan to death. And His Majesty the Dragon Emperor's practice is not difficult enough to stump a Yuanshen cultivator at the Qi training stage, let alone the practice of the Yuan Clan?

As a last resort, the part of the technique that can be cracked was handed over to the professionals of the Wanfa Sect and the Guiyi League.

The fastest conclusion was drawn by the Wanfa Sect. According to the analysis of the Wanfa Sect, this technique is essentially an ordinary technique - except that the structure is biased towards the body training technique, there is nothing too advanced.

Compared with the Qi training parts of other Yuanying techniques collected by the human race in the universe, there is nothing too great.

There is no encrypted part either.

If there is a "technical barrier", then that barrier is definitely not in the technique, but in the Yuan Clan itself.

It cannot be explained.

With a little "little help" from the Dragon Clan, some human cultivators successfully mastered the shapeshifting method of the Yuan Clan. Judging from the scale of the source of life, these humans should be completely Yuan Clan.

However, they just can't enter smoothly.

"I knew it wouldn't be so smooth." After hearing the news, Zhan Woshen cursed for a long time: "Those dragons are here to laugh at me - they already know that simply forming the Yuan Clan will not help them practice the Yuan Clan's skills! They must know! They have no good intentions..."

Ke Li Ke finally stopped him, so that this broken mouth would not affect the diplomacy of the human race.

But...

- It doesn't make sense?

If the secret of the Yuan Clan lies in their flesh and blood, then the cultivators who have embedded the flesh and blood of the Yuan Clan into their own bodies should be able to enter, right?

Or, is there another mystery about the soul of the Yuan Clan?

As the sun's direct point passed the equator and approached the Tropic of Cancer, the air began to get hot.

The cultivators were also a little impatient.
