Beneath the night sky, the crystalline dome cracked.

The blood-colored dragon's huddled body stretched as the immensely strong main wing and massive ailerons unfolded at the same time.

At this moment, his body size officially broke through forty meters.

The forty-meter behemoth, at the moment when it appeared in the center of the nest platform, there were no nest dragons to greet it with the ritual of awakening day.

Because, this is his pure strength, in the process of artificial evolution, he took the initiative to break free.

In his field of vision, the countdown to the core has not stopped.

"Sure enough, the time correlation of countdowns and the like is directly related to this serotonin-like substance."

"But, I didn't expect ......."

Di Xing stretched out his strong forelimb arm claws, and in his claws, a cloud of bright red blood changed color slightly between red and blue.

When the blood in his hand turned blue, a wave of vitality that was different from him formed.

The stronger vitality and stronger blood energy gave him the ability to touch and change the microscopic realm and interfere with the cellular and genetic levels.

He tried to explore the "life force fluctuations" or-

Trying to explore the nature of "life force".

Just as he had guessed before, "Life Force Fluctuations", those magical elementary particles, are the basic units of life force.

It can be said that the difference between blood energy fluctuations and ordinary life force fluctuations is close to the difference between different frequency wavelengths of electromagnetic waves.

However, the torrent of blood energy that he is accustomed to using, called "blood energy", is actually closer to plasma, and is a mass of things that is somewhat close to "plasma".

In essence, the earth line doesn't know much about plasma, only a basic -

The fourth state of matter other than solid, liquid, and gaseous.

This is called "plasma".

This is a state of conductive substance that conducts electricity very easily.

Let's put it this way, the shining orbit formed by the ionization of the air by lightning, and the ionized gas in it is plasma.

For example, flame is a special state similar to that of plasma.

By rough analogy, the relationship between "blood energy fluctuations" and "blood energy" is like the relationship between the light emitted by lightning and the plasma in the lightning orbit.

A more popular analogy is the relationship between the smell of a snake's skin and the rest of a snake that has been skinned.

These detailed theories are important for the ground, but more important are the applications.

In the universe of previous lives, plasma was the main form of existence of matter.

And it is well known that electric magnetic fields can be used to control plasma.

And through wires and currents, electric fields can be created.

In the past, Jixing has always been curious about the existence of such powers as "spells" and "quasi-spells".

And now......

In essence, a spell or a spell-like spell is a force field of different shapes relative to blood energy and the "electric field" and "magnetic field" that fluctuate relative to blood energy.

As long as there is a flow of life force, matter becomes stronger and more closely connected, which in itself is the result of the life force field of life force.

And just like the color reaction of the flame and the color of the light, different lifeforms will have different blood energy and blood energy fluctuations.

….

He placed the blood in the nest.

Then, when he tried to use the power of the core to use this mass of blood as the evolutionary target, sure enough, it failed.

I had always wondered why the [Core] couldn't directly evolve outside of itself, and couldn't directly evolve individuals outside of the nesting dragon.

In essence, it's not complicated.

It is to specifically target the vitality fluctuations within a "frequency" range, and use the vitality that can produce such fluctuations as the standard for identification.

And now, the moment the principle became clear, he immediately reversed

Xiang traced to his own body, where the body of the [core] is.

As a result, the land line was also slightly surprised.

In essence, if you want to talk about proportion, in fact, the [core] occupies the vast majority of his body, and in terms of the correlation and matching between them-

He, the earth, and all the memories and knowledge related to the earth, and the personality related information, are the foreign body, the foreign body that does not match the various functions.

He's an implanted foreign body.

Although, at this moment, the earth can almost declare that as long as you want to, then you can completely detach yourself from the influence of the core at any time.

But......

It is precisely because of this discovery that the question also arises, who created this [core]?

Who implanted him, the fragment of information about the foreign body of the earth, into this core?

What is the purpose?

Jixing thought of the bone-like bird-like skeleton he had encountered before.

It reminded him of Gestalt consciousness and hive will creatures, undead beings who could directly affect his body.

The judgment of the earth bank at the beginning was not wrong.

The core, judging from the current clues, does come from that group of undead.

It can even be said that it is part of the group of undead.

But......

That group of undead seems to have a close connection with the elves of the elven kingdom.

Jixing turned his gaze to the blue blood dragon that was squirming slightly above the nest platform.

Like a mollusk, the blue blood dragon, which was somewhat close to the small lepidoptera, seemed to feel the pressure of his life force, and was instinctively crawling towards the outside of the nest.

Although it has no memory or cognition, it instinctively connects the outermost blood flowing through the blue blood energy to form "skin and flesh", which envelops the blood flowing in the body.

In this way, it squirmed and crawled in a strange form close to tentacles, close to that of mollusks.

However, the next moment, the moment Zai Xing stretched out his claws and placed them on the edge of his body, and the moment he could bleed out, it was provoked to react-

The dark blue blood energy gathered close to the claws of the earth.

Merely.

Because of this action, the rest of its body loses its blood energy and gathers to form an "outer layer of flesh".

Blue blood flowed out in the next moment.

This new life, which was born only a few minutes ago, died of weakness after a brief struggle.

This also made the earthly line's thoughts focus on this blue-blooded dragon.

Blue blood.

Red blood.

When I saw the blue blood, the first thing that came to mind was all kinds of arthropods and molluscs.

….

For example, spiders, scorpions, shrimps, crabs, horseshoe crabs, snails, octopuses, squid、.......

Historically, blood proteins have undoubtedly been used to store and bind oxygen.

Compared with hemoglobin, hemocyanin is relatively primitive.

It is well known that at the beginning of life on Earth, oxygen concentrations were not as high as they are now, and almost all oxygen was locked in compounds containing oxygen atoms, such as water molecules.

The vast majority of single-celled organisms that existed at that time directly relied on the decomposition of other substances to obtain energy.

Now, they are called anaerobes.

Oxygen, for them, is poison, it is highly toxic.

And the first mass extinction, the mass death of anaerobic bacteria, was caused by oxygen.

So, how did a species that did not die because of the poison of oxygen be prevented from dying?

There is a hypothesis that is-

Tyrosinase.

However, during this period, there is a class of anaerobic bacteria with tyrosinases, which can absorb and integrate oxygen into the molecules, thus avoiding oxygen poisoning.

After that, these can be combined with oxygen, separated from oxygen, and gradually develop a system structure that can earn the difference in price to obtain energy as an energy supply.

This is the origin of hemocyanin and hemoglobin.

There is a hypothesis that tyrosinase is the precursor of hemocyanin.

Hemocyanin, which is a copper protein, is literally, a protein containing copper elements, when it is not combined with oxygen, it is colorless, and when it is combined with oxygen, it is blue.

Hemoglobin, as we all know, is ferritin, and before and after combining with oxygen, it is bright red and dark red.

For hemocyanin, there is not much interest in the ground line.

In a previous life, hemocyanin had a lower utilization efficiency for oxygen-binding separation than hemoglobin.

In other words, the energy supply system is inefficient.

Even if the blood supply system is not replaced, arthropods can be metabolized more efficiently if they can change to hemoglobin.

But in this world, there is no need for this.

It should be said that the use of oxygen as a raw material for energy supply is a relatively inefficient option.

Di Xing doesn't remember or understand the details of the structure and molecule of hemocyanin in his previous life, but according to his judgment, this kind of blue blood may be the same as hemocyanin in his previous life.

At least......

Like the current nest dragons, it is a new structure that has been adapted to the other world and has a plausible structure.

The hemoglobin of the nest dragons is not the same as the hemoglobin of the original dinosaurs that have not gained vitality.

The former can be used as a life force and as a carrier of blood energy.

The latter, no.

And these hemocyanins may also be related to the previous life, but they are also a new structure after evolution.

However, it is more important to .......

They have a special binding effect with the "water elemental".

In terms of the use of "water element", this protein is stronger.

However, Dixing didn't really care about this aspect.

What he cares more about is the protein itself.

The reason why it is said that its predecessor may be tyrosinase is because it has copper ions in its molecular structure.

But more importantly......

Tyrosinase, which is involved in melanin synthesis, is a rate-limiting enzyme that regulates melanin production.

In simple terms, the higher the tyrosinase activity, the greater the amount of melanin formation.

Melanin, a substance that can be used to buffer ultraviolet light and other radiation energy, is present in a variety of organisms.

However, in the previous life, in this direction, the energy that absorbed and buffered radiation was used for its own energy supply energy cycle, and a set of "radiation synthesis" was constructed, except for fungi, there are almost none.

Also, the size of these fungi is too far from that of multicellular organisms.

In addition, it is not enough to have only the core functions, and other supporting systems are also needed.

If the earth wants to evolve this energy circulation system that uses radiation synthesis in its own body, then hemocyanin is far more suitable than hemoglobin.

As for the energy supply system that combines with oxygen and uses oxygen?

Does that matter?

Of course, the charm of evolution lies in the fact that some structures that seem to be wasteful and redundant have shown unexpected surprises at a certain point in time because of their diversity.

Red blood may still have a certain role at some point in the future, and the earth will not be directly abandoned.

But there is no doubt that the local bank will focus on this supporting structural system with melanin as the core and related to blue blood.
