After receiving the bizarre case, the Thirteen Institute immediately went to the new university town of Wudu to investigate, and then found that the time when the nine girls disappeared happened to be in the time period when the university town was preparing for the school celebration. In other words, the new type of university town in Wudu is about to usher in its sixtieth year, that is, the year of Jiazi in Wudu University Town. There is an old saying among Chinese folk that it is called sixty-one jiazi, nine turns and one reincarnation.

The Jiazi year mentioned in this sentence is a method of calculating the age according to the ancient dating method of our country, using a specific chronological method of the heavenly stem and the earthly branch. The specific method is that the heavenly stem is divided into ten parts, namely, A, B, C, D, E, G, G, XIN, NON, and DEC. The earthly branch is divided into twelve parts, namely Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai, and then combine the heavenly stem and the earthly branch together to carry out the chronology, similar combinations are: Jiazi year, Yichou year, Ding Yin year and so on.

Because, by extrapolating these chronological methods, that is, the ten numbers of the heavenly stem and the twelve numbers of the earthly branch, the least common multiple of the two is 60. The first Jiazi of the Tiangan and the first son of the earthly branch have to form the first year of the epoch, counting from the first Jiazi year, that is, it takes another 60 years, so the old saying says sixty-one Jiazi.

As for the latter sentence, nine turns and one reincarnation involve one percent of numerology in nine, that is, some people say that alchemy needs to pass three levels, and after seven turns, nine reincarnations can return to the pill. This is the supreme cultivation part of metaphysics, that is, the yang god is received into his own body, cultivated repeatedly, and then the body is refined into the yang god, and then the yang god is forgotten and integrated into the Sanqing Void Dao realm, that is, the Dharma realm called by Buddhism.

Then refine the physical body into the Yang God Void Dao, and the form manifested in the world is that there is no shadow under the sun, and if you gather, you will form and disperse, and you will become qi. What kind of state such as soaring in the daytime and becoming an immortal is the same realm level as the deadless body of Tantra. Of course, these mysterious and mysterious things are not something that can be explained by normal scientific knowledge and can be understood by ordinary people.

These are mentioned in order to illustrate these two sentences, which confirm the statement of some superstitious old people that something big will happen in the year of Jiazi. For Wudu University Town, this year coincides with the 60th anniversary of the school, and it is also the year of Jiazi in the university town. As the country's first model university town, the national level attaches great importance to this matter, so the entire foggy city from top to bottom, from the leaders of the city to the management team of various colleges and universities in the university town, have been preparing for the school celebration one year in advance.

At this time, female college students in the university town of Wudu began to disappear frequently, and this news made the leaders feel like pins and needles. Everyone felt that their backs were cold and sweaty on their heads, lest the news spread and cause panic and unnecessary trouble among everyone, and then the leaders above would blame themselves. Therefore, from the leaders who directly manage the university town to the leaders in charge of the universities, everyone has invariably adopted a low-key approach to the disappearance case.

The first girl who went missing was before the winter vacation last year, that is, at the beginning of this year, at the end of January. This girl is a junior at the University of Posts and Telecommunications, named A, the only daughter of an urban working family, and a local student in Wudu. On the day she disappeared, it was the third day after the final exam, and she was supposed to go home for winter vacation like everyone else in the dormitory, but because her boyfriend's home was out of town and the train ticket she booked was the day after tomorrow, A didn't go home and wanted to spend more time with her boyfriend at school.

The thing happened that night, A and her boyfriend ate hot pot at the small restaurant at the school gate, she was just about to take her boyfriend to go shopping, and she was coquettish and pretended to be angry, but her boyfriend was still very persistent, he said that night was the finals of the game league, and he made an appointment with his teammates to play the level, and he must not miss the appointment. In the end, I had no choice, so A had to compromise very unhappily and accompany my boyfriend to the Internet café.

I didn't expect my boyfriend to leave after the finals, but the more I played, the more excited I became, and I didn't have any intention of leaving at ten o'clock in the evening, I was very angry about this matter, and I felt that my boyfriend didn't understand and love herself at all, and she saw that the girls' dormitory was about to turn off the lights and close the door, so she left the Internet café alone in a fit of anger.

At that time, A's boyfriend didn't know whether he was really playing a game, he was so forgetful that he didn't care about it, or he didn't want to do anything, he didn't pay attention, or he didn't care about A at all, anyway, it was so late, after girl A left alone, he still insisted on playing games in the Internet café, and he didn't chase out to find A at all.

The next morning, after A's boyfriend came out of the Internet café after staying up all night, he didn't care about whether his girlfriend went back to the dormitory, but went directly to the dormitory to sleep with his head covered, and slept until the night before getting up. After getting up, A's boyfriend remembered to look for her, but as a result, he called A's mobile phone to turn off and went to the dormitory building where A lived to find someone, only to find that A had not returned to the dormitory the night before. Her boyfriend called A's home again, and A's parents told him that A's was not home.

Because girl A and her boyfriend always quarrel, usually when the two quarrel, A will hide so that her boyfriend can't find it. So she couldn't find A this time, and her boyfriend thought she was deliberately hiding again and had an awkward fight with him. The boy is used to this routine, and he is tired of girl A always threatening herself with disappearance, so her boyfriend did not look for A anymore, but chose to take the train home by himself.

At this time, A's family always thought that she and her boyfriend were at school, plus the children who were in college, and it was normal to make a phone call to the family in two or three days.

The police found that A had indeed returned to the school from the southeast gate of the school on the night of the quarrel. Follow-up monitoring also showed that after A entered the school, she never left, that is, girl A has always been in the school. It's just that the cameras in the school are not popular enough, and some of the surveillance has been broken for a long time, and the pretense is the same, so where A went after entering the school has become a mystery.

It stands to reason that the personnel of the school are strictly checked in and out, and the security in the school has always been very good, and there has never been a bad incident. What's more, at that time, the school had already closed for winter vacation, and there were not many people left in the school, many classrooms and venues had been closed, and there were not many places for A to enter.

But in order to give an explanation to the parents, the school organized personnel to cooperate with the police to conduct a careful inspection of every corner of the school, which was a very detailed carpet search, but in the end no trace of A was found. From then on, the girl A did not see anyone alive or dead, and disappeared in the school out of thin air.
