The difficulty of breaking through biology brings another problem.

In October 2020, a full year and three months after Huang Si came to this world, his body began to be a little unable to hold on.

No matter how much the strength of the soul increases, it can't replace the body, and now his ability to resist pressure has become stronger, which is a good thing, but the weakness of the body is indeed real.

Huang Si often felt unwell. This trend, even if he insists on taking vitamins every day and exercising, cannot be reversed.

And he is not familiar with medicine, and he is helpless about his situation.

"It would be nice if I were more familiar with the structure of the human body, maybe I could change my body with my mind and erase some of the lesions."

Huang Si slightly regretted that his previous research and development direction was all foreign objects, and now, he has no understanding of his body, even if he can see that his liver, kidneys, spine and other places have obvious lesions, but he has no idea how to improve at all.

What's more, many lesions in the human body are difficult to reverse once they have changed, and they are almost permanent damage.

Huang Si didn't know how long he could live, he only knew that he should start preparing for the rollback.

Since discovering the declining body functions, Huang Si began to write a guide document for his future self.

In addition to this, he still keeps a diary and records all his findings and achievements in great detail.

In March 2021, Huang Si's body finally collapsed. Severe malnutrition and a closed environment destroyed his health.

It had been a year and eight months in the darkness, and he had not encountered any danger in the darkness, but he had not found a way back, and he was dying.

The pain had made it impossible for Huang Si to concentrate and continue his research, and he put down what he was doing and felt his physical condition.

"I'll probably have another month or two to live? No, there's no need to delay it that long. ”

With his current body, he can't do anything, and Huang Si is determined to prepare for a rollback.

He pasted the guide book in the most conspicuous position, and then lay down comfortably on the bed.

Huang Si's consciousness connects to the creation book, and he experiences the rubbing he left more than a year ago.

Before he rolled back, a philosophical question suddenly occurred to him.

What is Personality?

It's a unique conscious individual made up of countless memories, right?

In folklore, the dead would drink Meng Po soup in the Yellow Spring, forget all about the past, and then be reincarnated.

Did even the ancients know that memory is the essence of personality?

After the memory is removed, the person is no longer that person, but a different individual.

Now what Huang Si encountered is not so extreme, but in the short period of one year and eight months here, the things he has experienced and learned are far richer than what he has experienced in his previous 25 years of life.

And his mind has grown considerably.

Now, Huang Si is no longer the otaku he used to be, and his whole mental state has changed a lot.

The strength of the soul can be measured by various values of creativity, but the change in mentality and realm can never be measured.

Now Huang Si has initially possessed the psychological qualities that a person who has achieved great things. However, if he is retracted, although the soul strength is still retained, all the benefits of the experience will be lost.

A strong man's broken wrist is nothing more than this, which is simply removing a part of his personality.

However, Huang Si's mood is very calm, and his strong mentality and superb realm make him very clear about what he wants.

He needs to keep alive and accomplish his goals.

"Goodbye, now me. If I can reach my current spiritual state once, then even if I lose all my memories, I will definitely be able to do it again. ”

Huang Silian creates the book, reads, covers.

In the next moment, Huang Si jumped up from the bed with a panicked expression, but he soon saw the lines of handwriting posted on the wall:

"To me after being born again:

"It's a guide, maybe you've just experienced something strange and you're confused for a moment, you don't know what's going on, and you don't know why it's the way it is. Actually, it's March 9, 2021, and you need to calm down and accept all the things I'm going to tell you next. ”

The latter part is a general overview of what happened in the past year and 8 months, and finally, the text guides Huang Si to the study to look at the 34 notebooks on the bookshelf, as well as the 001~457 documents starting with LOG in the computer.

Now Huang Si's memory has recovered to become a blank feeling when he has only been here for five days.

But what is written on the note on the wall should be true.

It's not just because of the handwriting, and it's not just because he does it.

What's more......

Huang Si glanced at the bed around him, and with a movement of his mind, the pillow on the bed flew up directly out of thin air.

The pillow transcends the rules of physics and is silently suspended in the air.

Yes, before the great collapse of his physical condition, Huang Si's soul strength had reached the point where he could control objects to fly against gravity. Compared with the time when I first reached the "inspection" stage, I could only open a window, which has been greatly improved.

At this time, Huang Si did not have so many painful and complicated memories since then, his mentality was still very relaxed, he felt the strength of his spiritual consciousness, he only felt very interesting, and after a while, he broke a small piece of wood, and then controlled it with his mind, scurrying around the room like a flying sword.

It took Huang Si more than ten days to read the records on the bookshelf, and another week to read the records on the computer, and also familiarized himself with the use of various devices at home.

Now there is electricity at home, air conditioning, you can watch movies and play games, and there is even a virtual world in the computer, where a group of AI interact, Huang Si finds it very interesting.

In terms of eating, there are artificial meat and artificial gluten, and drinks include wine, rice vinegar, and sugar water.

Huang Si sat in front of the computer with cookies and sugar water, opened a movie, and watched it with relish.

On April 27, 2021, Huang Si has regained most of the previous scientific research results after the rollback, thanks to the extremely detailed records he left before the memory rollback, which can be said to have recorded his entire research and development process, all the data, and all the ideas.

From March 9 to April 27, Huang Si completed the continuation of the results of the previous year and eight months in more than a month.

After that, Huang Si began to continue to advance research and development.

He did not slack off in the use of the creative forces and in the exercise of the soul.

Time passes.

In December 2022, Huang Si once again felt that his body was about to collapse, and Huang Si, who had already had a rollback experience, did not panic at all.

At this time, he has developed a robot that can act on its own, and many things in the house are helped by robots, which is very convenient. The main unresolved issue is energy. It's just that the solar battery is powered, and the efficiency is too poor.

Huang Si has developed a battery-powered solution, which only requires him to change the liquid in the battery regularly. But it's still a hassle.

Before this rollback, he left a much larger record of data.

Huang Si estimated that if he wanted to master all the research results after the rollback, it might take 4 months. However, he could not afford to delay, and as the research progressed, the results increased, and it may take longer and longer.

To this end, Huang Si made a plan, starting from the next retracement, his energy will focus on a certain field, and he will not pay attention to all records outside that field.

In December 2022, Huang Si pulled back for the second time.

After the rollback, he saw the record he left behind, and understood that he needed to specialize in robotics after this rollback.

So he just picked and read the numbers 19, 23, 34, 35, 52, and 57 of the notes, and then went to the computer and searched for all the relevant parts.

Accepting the results of the past, this time it only took 17 days.

Huang Si immediately invested in research and development, perhaps because of the continuous improvement of his soul strength, it was now easier for him to adjust his mental state. It didn't take much time for his state of mind and spiritual realm to quickly reach a very high level.

Therefore, his R&D efficiency has also been improved several times.

In fact, he has been here for several years now, but Huang Si doesn't care anymore, he has to go back, but he doesn't think about other worries anymore.

In March 2023, Huang Si put 10 small detection robots at the gate.

The robots are powered by jet energy, the easiest way he found to move freely in the dark.

The robot comes with its own camera and touch sensor, and Huang Si sits in front of the computer and monitors the robot's movements.

Now for convenience, Huang Si has copied an additional computer, the previous one is used for R&D and monitoring, and the new one is used to raise artificial intelligence, because now the database of artificial intelligence is getting bigger and bigger, and they have become very humane.

He also set up a disk array to store data.

Huang Si controls the robot's movements, he divides the dark area around the house into multiple sections, and lets the 10 robots spread out and slowly explore the past.

At this time, Huang Si could already try to condense objects in the dark space, but the range of his spiritual shroud could only extend out about 12 meters at most, and the dark space could not be blocked.

In other words, when the robot needs to replenish energy, as long as it is close to the room within 12 meters, Huang Si can use the creative force to replenish it, and then let it continue to explore outward.

The dark space was still dark, not only was there nothing, not even the garbage that had been thrown out before.

Huang Si was puzzled, why did the garbage disappear?

Now the robot can only continue to explore the dark space. Huang Si hopes that this exploration will reveal something.
