The difficulty of biological breakthrough brings another problem.

In October 2020, a full year and three months after Huang Si came to the world, his body began to be a little overwhelmed.

The strength of the soul can\'t replace the body. Now his pressure resistance has become stronger, which is a good thing, but the weakness of the body is really real.

Huang Si often feels uncomfortable. This trend, even if he insists on taking vitamins and exercising every day, can not be reversed.

He was not familiar with medicine and was helpless in his own situation.

"If only I were more familiar with the structure of the human body, maybe I could change the body with my mind and erase some lesions."

Huang Si slightly regretted that his previous research and development direction was all foreign objects. Now, he has no understanding of his body, even if he can see obvious lesions in his liver, kidney, spine and other places, but he completely doesn\'t know how to improve.

Moreover, many lesions of the human body are difficult to reverse once they change, which is almost permanent damage.

Huang Si doesn\'t know how long he can live. He only knows that he should start preparing for his return.

Since he found that his physical function was failing day by day, Huang Si began to write a guiding document for his future.

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

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

It was a whole year and eight months since he came to this darkness. He did not encounter the danger in the darkness, but he did not find a way to go back, and he was about to die.

The pain has made Huang Si unable to concentrate on his research. He put down his work and felt his physical condition.

"I\'ll probably live another month or two? No, there\'s no need to wait so long."

Now the body can\'t do anything. Huang Si is determined to go back to gear.

He put the guide paper on the most prominent position, and then the whole person lay comfortably on the bed.

Huang Si consciously connected to create books and experienced the rubbings he left more than a year ago.

Before returning to the file, he suddenly thought of a philosophical problem.

What is personality?

Is it the unique conscious individual composed of countless memories?

In folklore, dead people will drink Mengpo soup in the yellow spring, forget everything in the past, and then reincarnate.

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

After removing memory, people are no longer that person, but another different individual.

Now Huang Si\'s experience is not so extreme. However, in just one year and eight months here, he has experienced and learned much more than he had experienced in his previous 25 years of life.

And his mind has grown considerably.

Now, Huang Si is no longer the house man in the past. His whole mental state has changed greatly.

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 quality that a person who has achieved great things should have. However, if he is put back into gear, although the soul strength remains, all the benefits brought by experience will be lost.

There is no better way to break one\'s wrists than this. It is simply removing a part of one\'s personality.

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

He needs to continue to live and achieve his goals.

"Goodbye, I am now. If I can reach the current spiritual state once, even if I lose all my memory, I can reach it again."

Huang Si connected the creation book, read and cover.

The next moment, Huang Si jumped up from the bed with a panic expression. However, he soon saw the lines of writing pasted on the wall:

"To me after rebirth:

"This is a guiding document. Maybe you have just experienced strange things. For a moment, you are very confused. You don\'t know what happened and why it became like this. In fact, it is March 9, 2021. You need to calm down first and then accept all the things I will tell you next."

The latter part is a general overview of what happened in this year and eight months. Finally, the text guides Huang Si to the 34 notebooks placed on the reading rack in the study and the documents 001 ~ 457 starting with log in the computer.

Now Huang Si\'s memory has been restored. When he first came here for only five days, his heart was at a loss.

But the note on the wall should be true.

Not only because of his handwriting, but also because he can do these things.

More importantly

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

The pillow goes beyond the physical rules and floats quietly in the air.

Yes, before the collapse of his physical condition, Huang Si\'s soul strength had reached a level that could control objects to fly against gravity. Compared with just reaching the "observation" stage, it can only open a window, which has been greatly improved.

At this time, without so many painful and complex memories since then, Huang Si\'s state of mind is still very relaxed. He feels that his spiritual consciousness is strong. He just feels very interesting. Not long ago, he broke a small piece of wood, and then manipulated it with his mind, running around the house like a flying sword.

It took Huang si more than ten days to read the records on the bookshelf. It took another week to read the records in the computer and get familiar with the use of various devices at home.

Now there is power supply and air conditioning at home. You can watch movies and play games. Even there is a virtual world in the computer. There is a group of AI interacting there. Huang Si thinks it\'s very interesting.

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

Huang Si sat in front of the computer with cookies and sugar water in his arms, opened a movie and watched it with interest. This day can be comparable to the original otaku life!

On April 27, 2021, after returning to the file, Huang Si has regained most of the previous scientific research achievements, which is due to the extremely detailed records he left before returning to the file. It can be said that he recorded his whole R & D process, all data and all ideas.

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

After that, Huang Si began to move forward in research and development.

He did not slacken his use of creative power and soul training.

time lapse.

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

At this time, he has developed a robot that can move by itself. It is very convenient to have robots to help with many things at home. The main unsolved problem is energy. It\'s just solar cell power supply. It\'s really inefficient.

Huang Si has developed a battery powered scheme. He only needs to change the liquid in the battery regularly. But it\'s still troublesome.

Before this return, he left more and more huge data records.

Huang Si estimated that it might take four months if he wanted to master all the research results after returning to the file. However, he can\'t afford to delay, and with the progress of research and the increase of achievements, it may be longer and longer.

To this end, Huang Si made a schedule. From the next filing, his energy will focus on a certain field, and he will no longer pay attention to all records outside that field.

In December 2022, Huang Si returned to the file for the second time.

After returning to the file, he saw the records he left and understood that he needed to specialize in robot related after returning to the file this time.

So he only selected the numbers 19, 23, 34, 35, 52 and 57 of the reading notes, and then went to the computer to search and read all the relevant parts.

It took only 17 days to accept the past results.

Huang Si immediately invested in research and development, perhaps because of the continuous improvement of soul strength, he is now easier to adjust his mental state. Without much time, his state of mind and spirit can 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. He has to go back, but he doesn\'t consider other worries.

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

These robots are powered by jet energy, which is the easiest way he has found to move freely in the dark.

The robot has its own camera and touch sensor. Huang Si sits in front of the computer and monitors the robot\'s actions.

Now, for convenience, Huang Si has copied an additional computer. The old one is used for R & D and monitoring, and the new one is used for artificial intelligence. Because the database of artificial intelligence is getting larger and larger, they have become very humanized.

He also set up a disk array to store data.

Huang Si controlled the action of the robot. He divided the dark area around the house into multiple zones, dispersed 10 robots and slowly explored the past.

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

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

The dark space is still dark. There is not only nothing, but also the garbage thrown out earlier.

Huang Si wondered why the garbage disappeared?

Now we can only let robots continue to explore dark space. Huang Si expects this exploration to find something.
