Satellite images from the computer are far less shocking than those from the scene.

This is a section of the canyon of a tributary of the Heilongjiang River along the Sino-Russian border. The river vividly split the mountain at the foot of Yu Qianhua into two sections, and the vertical cliffs like knives stood on both sides of the river. Looking down from the mountain, the whistling wind and snow blew the white expanse below, and it was impossible to see the frozen river below. Yu Qianhua looked at the sky, wiped the snowflakes off the solar panel with her hands, turned around and returned to the cave, and then zipped the cold blanket at the entrance of the cave.

Two days ago, Yu Qianhua found a leeward recess on the cliff on the south bank of the river, and used her internal force short sword and strong palm power to dig a small cave sheltered from the wind. Now she was sitting in the cave listening to the sound of the wind and snow, eating a cold nutritious meal.

This kind of package was purchased by her Zhang Fei from within the Martial Arts Guild for this retreat. It is said that this is a special product developed according to the physical needs of the martial arts, and it is currently only available to the five major masters and more than 10 members who are about to enter the micro. When she left Beijing, Zhang Feituo sent two boxes, enough to eat for a month.

Today is her first day of retreat, and she specially opened a package of this nutritious package to taste it, and the taste is acceptable, it has a lot of calories, and it is indeed more powerful than ordinary food. She is a typical person who grew up in the south, she has never seen such a big snowstorm, and she has never felt such cold weather. As a master of subtlety, she originally thought that with her ability, the weather would no longer be a reference factor for her travel. But after seeing the white-haired wind in the Northeast, she knew that she was a little overbearing.

When she came, she only wore a special white sportswear for martial artists. The white color was to match the snow here, and she didn't think about the temperature at all. Because the warriors can adjust the structure of the skin through internal forces, so that the skin forms a temperature-resistant layer, so that the warriors are not afraid of daily high temperature or cold.

The clothes, shoes and socks of the warriors are actually very particular. The reason is also very simple, it is to have high-intensity battles at any time. Imagine if two warriors fight, fists and feet, because ordinary clothes can't resist the strength of both sides, and after the fight, there is only a rag and two naked men left in the field. The battle at the pinnacle of martial arts masters turned into a naked brawl full of emotion, what is this like! Therefore, the warriors wore special clothes with strong toughness, wear-resistant and tear-resistant.

Yu Qianhua's sportswear actually has a certain thermal insulation effect, but in this extremely cold environment in the Northeast, it is a bit of a drop in the bucket. She had already used internal force to strengthen the temperature tolerance layer of her skin, but she still couldn't keep the cold out. But when she took a tube of nutritious package, she felt the heat from her stomach spread out with the blood, which immediately made her feel much more comfortable.

This morning, she had activated the reversal mechanism in her body, which was the beginning of her retreat. Her retreat is scheduled for ten days, during which she will reverse the flow of internal forces in her body and bring her brain back to the memories of her two-and-a-half-year-old years, with the aim of retrieving the messages that her skull master had taught her when she was young. This process takes about five days, and then she takes another five days to reabsorb her internal strength and restore her current mind and strength. The time should be just November 12, the day she and Zhang Fei agreed to keep the customs.

Although Yu Qianhua never went to school, she never stopped studying. The reason why she laughed at Zhang Fei for spending all the guild's money on scientific research was actually to pretend to be stupid and cover up her exploration in this area. Since she was a child, she has followed her older children to learn cultural knowledge, and when she is older, she has asked them to go to the bigger cities to borrow a large number of popular science books for her to read. Later, she learned English, and directly searched and read foreign cutting-edge literature on internal forces through the Internet.

In terms of her understanding of the human body structure and human body mechanics of the martial arts, she dares to claim to be world-class. She combines her own practice and the knowledge she has learned, and has formed a system from basic theory to practical practice.

Her theory is this: people use their five senses to perceive the world, but the world that people feel is definitely more than what you feel, that is, the complexity of the world is definitely beyond the scope of human perception. There must be a large amount of imperceptible information and reality that exists behind the surface world, which she collectively calls the dark world.

She believes that the particle of internal force is a substance in the dark world. It is like an iceberg and the sea, with only a sharp horn on the surface of the water, and its huge volume is hidden under the iceberg. This is similar to the fact that only a few martial artists can sense internal forces in their bodies, while humans cannot detect the huge internal force particle clusters of the dark world.

The idea that there are a large number of internal force particles in the dark world is Yu Qianhua's conjecture. Her other conjecture is that there must be a secluded realm above the subtle realm, and when it reaches this realm, the martial artist will be able to see through this blindfold that covers the eyes of the world and get a glimpse of the mysteries of the dark world.

The reversal mechanism she practiced was to send the internal force in her body back to the dark world little by little, dismantling and reorganizing her mind from the internal force structure little by little, and finally reaching the point of returning her mind to the age of two and a half, and then she would use the "can't find" that had been installed in the center of her eyebrows, and use this new audio and video recording equipment to try her best to record her feelings, behaviors, and thoughts at that time at the age of two and a half years old. When she can no longer resist the invasion of her body by the internal forces of the dark world, she will give up resisting, so that she will quickly recover her current level of internal force and let the internal force re-complete the structure of her mind. After returning to normal, she used the information recorded by "Can't Find It" to interpret the cultural heritage left to her by her master at that time with the thinking of an adult.

The reason why she used "can't be found" was because she had briefly experimented with this reversal mechanism, and although it was only a few milliseconds, she was keenly aware that she had a time difference in these few milliseconds. In hindsight, it felt like going back in time, so she imagined that if her mind went back to two and a half years old, she might only remember what happened when she was two and a half years old, and not about herself now at twenty-one. That's why she thought of recording her reversal. So that when she recovers to her adult mind, she will look back at the process. Her purpose is threefold, one is to recall the teachings of the Master. The second is to explore the changes of internal force on the mind of martial artists. The third is to take this opportunity to break through to the subtle realm in one fell swoop, and it is best to have a glimpse of such a high-level realm as the secluded realm.

Before starting the retreat, she made a lot of preparations, the small cave was full of food, water, a small solid-fuel stove, enough fuel, a special thickened sleeping bag, a large collapsible plastic mirror (to record her words and actions), a solar-charged device, and a regular pistol for self-defense in case of internal weakness. She even used a rope lance to shoot a spare thin steel cable at the opposite bank, more than a hundred meters away, which was fixed about a meter below her hole. This was in case of an accident when she was only two and a half years old and she was at her weakest, and she had to have a way out.

She placed her mobile phone in a conspicuous place, and the mobile phone would play a self-recorded profile at regular intervals four times a day, telling her mind that she was in retreat and the content of her cultivation, urging herself to practice according to the content, not to go out of the cave, to eat on time, to drink water, and so on. Of course, it will also automatically replay every time the phone is used.

She was supposed to be in the state of mind to go back four to five years in a day. It was the first day, and so far so good, she managed to return to her eighteen or nineteen years old self in about ten hours.

But unfortunately, she is no longer the self she was when she was twenty-one, so she has not noticed any change in her appearance. In the mirror, she is a little more immature, the fluff on her forehead is also finer, and her eyes are no longer as wise and sharp as before, but have become a little simple and clear.
