Dawn of a New Era

Chapter 727: Evil Path

In the middle of the night, everything is quiet.

The roar of factory machine tools could be heard faintly in the distance.

Chen Shouyi was lying on the bed doing the most basic meditation exercises.

A huge picture of the human body with details down to the molecular level is reflected in the mind, and the dust is completely visible, and the astronomical level of information floods into the brain like a tide.

Every part of the body, including the brain, is full of light, without the slightest shadow, and every cell is like a small light bulb that is powered on, emitting a faint and mysterious brilliance of will.

Like an independent living body.

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

His nerve fibers are surprisingly thick, and the nerve endings are extremely dense, like tree roots covered with tentacles and forks.

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

Both of these are his shortcomings.

It's a pity that the former can still burn faith points to make up for it, but the latter has nothing to do except to practice harder.

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

He suddenly had a feeling: 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 nerve myelin.

height.

This cannot be changed.

Even if it can be changed, he is not willing to become shorter.

thickness?

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

Almost twice as much as ordinary people.

And more dense.

Most importantly, the risk of directly modifying nerves is too great.

The nervous system is quite complex.

Every neural activity involves complex chemical reactions.

The frequency of each electrical pulse is different, which represents the difference in the sending signal. When many nerve cells work in harmony, people can see, hear, smell, taste, feel pain, and even feel happiness and sadness.

This is a chaotic and complex system, and a single hair can affect the whole body.

Myelin, by contrast, is much simpler.

It has only three functions:

One is that the supporting axons are insulated from the surrounding tissue, such as adjacent axons, to avoid interference, which is equivalent to a layer of insulation in a bare wire.

The second is to speed up the transmission of action potentials through a mechanism called jump conduction;

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

Even if it is destroyed, it will not affect nerve transmission much.

At most, the signal will slow down by fifteen times.

In fact, the nervous systems of some invertebrates, such as some cephalopods, crustaceans, and insects, are completely devoid of myelin.

The pain-temperature sensory nerve fibers and autonomic postganglionic fibers of mammals also have no myelin sheath. Of course, these nerve fibers often exist in the same nerve bundle as myelinated nerve fibers.

The more Chen Shouyi thought about it, the more feasible it became.

I can't lie down anymore.

He pulled out the two little ones from his chest, put them aside, 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 get stronger.

Now his cultivation speed has become slower and slower, almost stagnating, and he has to be forced to think about evil ways.

He stopped suddenly, went to the desk, picked up a glass of cold water, and drank it down.

Then try!

...

Two principles of natural evolution.

One: Evolution is directionless and random.

Two: Enough is enough.

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

Since humans walked upright, the problem of dystocia has run through the entire human history like a nightmare.

In ancient times, for women, childbearing was equivalent to stepping into the gate of hell. It was not solved until the invention of caesarean section.

Of course, in turn, this also caused the normal natural selection to be interrupted. In the past century, the proportion of babies with big heads has risen sharply, making it more difficult for women to give birth 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 to carefully observe the structure of the myelin sheath on the nerve fibers and the working mode.

Ten seconds later, he realized it in his heart.

In this kind of observation that goes deep into the molecular or even atomic level, there are no more mysteries in living things, and everything is clearly presented in front of him.

He discovered that myelin jumps signals primarily because of the unmyelinated section between two Schwann cells, a type of glial cell. The axon here is exposed, which is conducive to the formation of local currents between two adjacent nodes, making electrical signals conduct in a jumping manner, which greatly speeds up the speed of information conduction.

Then it's easy.

He immediately came up with three countermeasures.

One is to reduce the myelin sheath junctions on the nerve fibers and simplify the structure.

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 transform and strengthen the Schwann cells and Ranvier junctions on the myelin sheath to make them work more efficiently.

The third is to create some kind of superconducting structure.

Of course, the latter two, Chen Shouyi, had no clue yet.

But the former can be tried right now.

Chen Shouyi took a deep breath and chose a little finger on his left hand for the experiment.

Most of the Schwann cells were decomposed silently by the thought, exposing the nerve fibers in them, and then the nearby Schwann cells were elongated to cover the original space, and finally the structure was fixed.

Remodeling is easier than you think.

All the cells in his body are like commands to him, and the neurons are no exception, most of them have been completed with one thought.

Just a second or two.

The little finger has been completely remodeled.

However, when he opened his eyes, he found that instead of becoming more flexible, his fingers became dull and numb. He bent them with difficulty, his feeling and thinking slowed down by several beats, and his brows were furrowed:

Sure enough, it's not that simple. He thought thoughtfully:

Where is the problem?

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

He continued to experiment.

Affected the membrane potential again!

...

Well, is there anything you haven't considered?

...

Time passed little by little, and it was getting brighter. Chen Shouyi was lying on the bed without the slightest intention of getting up.

Lying down until noon.

He suddenly opened his eyes with surprise on his face.

It finally worked.
