City B, a courtyard with a door sign of "Institute of Special Geological Exchange".

It's outside of the boom zone, so there aren't many people on weekdays, and the yard is quiet, with little people walking around. Even if someone occasionally comes in and out, they are in a hurry, with different expressions, as if they are in a hurry to go somewhere. If it weren't for the main communication room, where there was still a gatekeeper, everyone would think that it was an abandoned institutional courtyard.

In a building in the courtyard, in a well-guarded room.

There are rows of wooden bookshelves filled with files, and the air is dry and dim, and the lights have to be turned on even in broad daylight.

On the desk under the lamp, an old man with thick spectacles is scribbling. After a long time, he put down the pen and breathed a sigh of relief, and slowly closed the file in his hand, only to see that on the cover of the yellow kraft paper file, the title of "Changing Skin Evil Art" was written in eye-catching red letters, and the file number was written in slightly smaller text below: 19920204, unsealing period: never unsealed......

……

1990, S City, China.

Cai Fan, male, born in 1956, is currently a freelance electrician in S City.

Cai Fan was raised by the master, and when the master went to the town to run errands, he picked him up when he passed by the station in the middle of the night. Because the master lived alone, and he didn't find Cai Fan's parents, he adopted him and gave him the name "Cai Fan".

Master's name is Cai Laishun, and he is a local Mr. Yin and Yang, who is the person who specializes in helping people deal with things like ghosts and evil spirits in those years. In fact, Cai Fan himself has always been not interested in these Shinto things, after the founding of New China advocated literacy, he wanted to respond to the call to study when he was a child, but the old man of the master did not agree, and asked Cai Fan to learn from him to be Mr. Yin and Yang. The old man gave Cai Fan a fate, saying that he was destined to commit a bad star, plus he was born with yin and yang eyes, even the crickets around him would be killed by him, and he was destined to be alone in this life, so he didn't have to worry about the saying that "three generations of yin and yang are extinguished, and three generations of Taoist masters are absolute" in this industry, so it is most suitable to be Mr. Yin and Yang.

Cai Fan felt wrong when he thought about it at the time, why was the old man who lived together fine, did the old man play some tricks to deceive himself?

The old man also saw Cai Fan's thoughts at that time, so he said that he himself was also a lonely man, and his life was very hard, and it was not certain who would be the two of them, so Cai Fan was so choked that he couldn't speak.

When I was a child, I practiced and walked Gang Bu (a kind of footwork when the Taoist priest practiced to exorcise evil spirits, which is said to have been created by Dayu in ancient times, also called Yu Bu), drawing talismans, and practicing mantras were forced, and because of this, Cai Fan did not care when he learned these, in his own words, if the old man has ten skills, he can learn three points by himself.

Cai Fan also asked the old man what kind of faction they were, but he didn't say it, Cai Fan thought that they were idle people with no sect and no faction, etc., and the old man felt embarrassed so he didn't tell it. It wasn't until much later that Cai Fan realized that things were not what he thought.

Although Cai Fan was raised by the master, the relationship between the two was not good, and not letting Cai Fan go to study was one of them, and the other reason was that the name Cai Fan read similar to "Caifan", and the children in the village called him "Fancai", so Cai Fan had to change his name with the old man more than once. However, under the old man's "cigarette stick regime", all rebellion will inevitably be suppressed by the cigarette stick in his hand.

When Cai Fan reached the age when he could take care of himself, the old man began to become mysterious and secretive, and he would disappear for a period of time from time to time, as short as one or two months, as long as half a year, where he went and what he did Cai Fan didn't know. It is said that Cai Fan is his apprentice, and he should be taken with him if there is anything, and this matter has seriously affected Cai Fan's quality of life, so he has put forward a "strong condemnation" and "solemn protest" to the old man about this matter, but he has not received any attention, because he is afraid of the "cigarette stick regime" in the hands of the old man, and over time, Cai Fan has become accustomed to this.

In 1980, the old man of the master suddenly said that he was going to Xinjiang, and explained some things to Cai Fan before leaving, Cai Fan didn't take it seriously at the time, anyway, the old man was going to "disappear" from time to time, but he didn't expect the old man to really disappear this time.

At the beginning, Cai Fan also looked for him, but he didn't even find a hair. It happened that there were several major events in Lop Nur that year (if you are interested, check it out yourself), and it involved the legend of the Great Northwest Ruins, and many people who went there at that time failed to come back. These things were spread all over the place, Cai Fan thought, this old man said that he would go to Xinjiang, it wouldn't be Lop Nur, it was not strange to be mixed in with his past and ability, so he broke off the idea of continuing to find the master, and Cai Fan didn't dare to go to that kind of place.

Cai Fan simply sold all his belongings and came to S City with all his savings, which was also one of the things that the old man confessed before he went to Xinjiang, but Cai Fan didn't take it seriously at that time. And the master also said at the time that he would look for him when he came back, Cai Fan didn't expect that the old man was arranging a way back for him.

A few years before the Master left, there was a major earthquake disaster in S City, with heavy casualties, and anyone who talked about it would shed tears. There are some sayings among the people, some say that the earth dragon turned over, some say that the Yin soldiers borrowed the way, and there are all kinds of things. The old man told Cai Fan that no matter what the reason was, S City would definitely not be very peaceful for a period of time in the future, and asked Cai Fan to go over and look at the dot after he left, Cai Fan thought that this old man must know something, but with his temperament, he couldn't get a fart sound, so he simply didn't ask.

Although he can live anywhere alone, Cai Fan has no other skills to make a living, and his skills naturally can't be publicized, he doesn't want to be caught as a propagator of feudal superstition, so he almost didn't starve to death when he first came to S City.

Fortunately, Cai Fan himself usually has nothing to do, and likes to think about electrical appliances, wires and other things, so he became a freelance electrician in S City, and the days after this slowly stabilized, and his income was barely passable, but Cai Fan didn't care, he belonged to the kind where one person fed the whole family and was not hungry.

Of course, a big man also wants to deal with his partner when he is old, but when he thinks of the life that the old man gave him, Cai Fan doesn't dare to think about it, for fear of killing people, others are not bad, and he can be regarded as having a craft, and after staying for a long time, occasionally a matchmaker wants to talk about matchmaking, so Cai Fan pushes it. Because of this, Cai Fan was not less pointed at behind his back.

The lonely and boring days made Cai Fan feel that he was no different from a salted fish, and he was also a monk salted fish. Fortunately, Cai Fan later adopted a local dog, and it was after the dog was added to the family that Cai Fan's life became a little more colorful.

Cai Fan still remembers that it was a rainy day, and the little white earth dog came to scratch the door in front of the house, although he felt a sense of sympathy when he looked at it, but naturally he couldn't take it in. But no matter how Cai Fan rushed, he couldn't get rid of this puppy, so he thought that this was your own choice, no wonder me, so he raised it, who knew that this breeding was 5 years, and there was nothing at all.

Cai Fan felt weird, and it wasn't until later that Cai Fan found out that this dog was very smart and spiritual, and the general evil was afraid of it, so he understood something.

Cai Fan himself didn't expect that he would stay in S City for 9 years.
