Late at night, it's quiet.

In the distance, the roar of factory machine tools can be faintly heard.

Chen Shouyi was lying on the bed, doing the most basic meditation and refining his body.

A large, molecular-level picture of the human body is reflected in the mind, and the astronomical level of information floods into the brain like a tidal wave.

Every part of the body, including the brain, is bright, and there is no shadow in sight, and every cell is like a small light bulb that is energized, exuding a faint and subtle light of will.

It's like a separate living entity.

At this time, his mind was attracted by a neural network that constantly emitted electrical impulses.

His nerve fibers are surprisingly large, and the nerve endings are incredibly dense, like tentacles and bifurcated roots.

If the brain determines intelligence, then the nervous system, including the spinal cord, determines agility.

And both of these are his shortcomings.

It's a pity that the former can also burn faith points to make up for it, but the latter has not done much except to cultivate harder.

As a result, every time it fights, it has a feeling of powerlessness and cannot be fully incised.

He suddenly felt something in his heart: "Maybe it's not impossible!"

He opened his eyes, and they sparkled.

Even as a high school dropout, he knows that the factors that affect the speed of nerve transmission are mainly related to height, the thickness of nerve fibers, and the myelin sheath of nerves.

Height.

This cannot be changed.

Even if he could, he didn't want to be shorter.

Thickness?

He sensed it and found that he was already very thick.

It's almost twice as many as the average person.

And it's more dense.

On top of that, it is too risky to directly remodel the nerves.

The nervous system is quite complex.

Every neural activity involves complex chemical reactions.

Each time the frequency of the electrical pulse is different, it represents a different signal, and when a large number of nerve cells work in harmony, a person can see, hear, smell, taste, feel pain, and even feel happiness and sadness.

This is a chaotic and complex system, which affects the whole body.

In contrast, myelin sheath is much simpler.

It has only three functions:

One is to support the isolation of axons from surrounding tissues, such as adjacent axons, to avoid interference, which is equivalent to putting a layer of insulation in bare wires.

second, to speed up the transfer of action potentials through a mechanism called "jump conduction";

The third is to guide the regeneration of axons in the case of some axon damage.

Even if it is damaged, it will not affect neurotransmission.

At most, the signal is fifteen times slower.

In fact, some invertebrates, such as some cephalopods, crustaceans, and insects, have a completely myelinated nervous system.

The mammalian pain and temperature nerve fibers and autonomic postganglionic fibers also do not have myelin sheaths, although these gods often exist in the same nerve bundle as the myelinated nerve fibers.

The more Chen Shouyi thought about it, the more feasible he felt, and he couldn't lie down anymore.

He took the two little dots out of his chest, put them to the side, got up from the bed, and walked around excitedly.

The experience of the past few days made him feel powerless and hopeless, and he couldn't wait to be strong.

Now that his cultivation speed has become slower and slower, he has almost stagnated, and he has to force him to think about the evil path.

He suddenly stopped, walked to the desk, picked up a glass of cold boiling, and drank it all.

"Then try!"

......

Two principles of natural evolution.

One: Evolution is directionless and random.

Two: It's good to be enough.

Life is a miracle of nature, but it is also imperfect, crude, and even patchwork.

Since the time when humans walked upright, the problem of dystocia has been like a nightmare throughout human history.

In ancient times, childbirth was equivalent to stepping into the door of ghosts for women, until the invention of caesarean section was solved.

Of course, in turn, this has also caused the normal natural screening to be interrupted, and in the past 100 years, the proportion of big-headed babies has skyrocketed, and it has become more and more difficult for women to have children naturally.

It can be said that since the birth of civilization, human beings have deeply intervened in their own evolutionary process.

......

Chen Shouyi did not rush forward, but went deep into his body, carefully observing the myelin sheath structure on the nerve fibers, as well as the working mode.

Ten seconds later, he realized in his heart.

In this kind of observation at the molecular and even atomic level, there are not many mysteries of living beings, everything is presented to him very clearly.

He discovered that the myelin sheath "jumps" signals mainly because of the unmyelinated portion between two Schwann cells, a type of glial cell. The axonal cord at this place is exposed, which facilitates the formation of a local current between two adjacent junctions, so that the electrical signal is conducted in a jumping manner, which greatly accelerates the speed of information transmission.

The rest is simple.

He came up with three countermeasures to this in an instant.

First, the myelin sheath knots on nerve fibers are reduced and the structure is streamlined.

For example, if you need to jump more than a dozen times, if you only jump six times, or even twice, the speed of signal transmission will undoubtedly be greatly accelerated.

The second is to modify and strengthen the Schwann cells on the myelin sheath and the Lang Fei junction to make it work more efficiently.

The third is to create some kind of superconducting structure.

Of course, Chen Shouyi has no clue about the latter two for the time being.

But the former can be tried now.

Chen Shouyi took a deep breath and chose a little finger of his left hand to experiment.

Most of the Schwann cells are silently decomposed by the thought, exposing the nerve fibers in them, and then elongating the nearby Schwann cells, covering the original space, and finally fixing the structure.

The transformation is easier than you think.

All the cells in his body are like an arm command to him, and neurons are no exception, most of them have been completed with a single thought.

Just a second or two.

The little finger has been completely transformed.

However, when he opened his eyes, he found that his fingers had not only become more flexible, but had become sluggish and numb, and he bent hard, feeling and thinking several beats slower, and his brows were furrowed:

"It's not that simple. He thoughtfully said:

"What went wrong?"

"Could it be that too many nodes are cleared, which affects the transmission efficiency of neural signals?"

He continued to experiment.

"It affects the membrane potential again!"

......

"Well, what's not to think about?"

......

Time passed little by little, the sky gradually brightened, and Chen Shouyi lay on the bed without the slightest intention of getting up.

I lay down until noon.

He suddenly opened his eyes with a look of surprise.

Finally it worked.

It felt like a body that had taken off a heavy shell. He hurriedly opened the properties panel:
