Teacher Yu, the class teacher, asked the students, "Students, what do you want to do when you grow up?"

"I want to be an astronaut and travel in space. "This is the squad leader.

"I want to be a scientist and study the most advanced robots" This is the study of ***.

"I want to be a PLA and defend our country. This was the answer of the representative of the physical education class.

"I want to be a writer and change the world with civilization. "It's, uh... I don't remember...

At this time, Teacher Yu saw that Xin Yifan, who was sitting on the edge of the last row, did not raise his hand, and his face was flushed, and Teacher Yu immediately called him: "Classmate Xin Yifan, what do you want to do?"

Xin Yifan stood up awkwardly, and it took a long time to hold back a sentence: "Teacher, I think... I want to go to the toilet. ”

"Hahaha," the students laughed.

Xin Yifan sat in a wheelchair and fell into memories, today I remembered an embarrassing incident when I was in elementary school, two days ago I remembered that I was beaten for bedwetting when I was a child, and I was found kneeling on the washboard by my parents when I changed my final grades.

Xin Yifan, a 28-year-old doctor of archaeology, was turned into a vegetative state in a car accident a year ago and woke up a month ago, waking up with most of his memory and speech skills. Now I can occasionally think of a little thing, the doctor told Xin Yifan's mother that it may be caused by damage to the language center of the brain, and there is no particularly good treatment now.

Xin Jianguo and Chen Xia worked in the border city, Xin Yifan was their only son, in order to take care of Xin Yifan, who had become a vegetative person, Chen Xia retired early and came to the capital. The hard work paid off, Chen Xia's careful care, her son finally woke up, and now he can still recognize her, and he can also signal her own thoughts, such as being hungry, wanting to go to the toilet, and wanting to watch TV.

Chen Xia looked at her son, the sorrow in her heart lingered, the smart and funny son in the past has now become like this, in addition to taking care of him, he can only pray to God to let him recover as soon as possible.

Speaking of the car accident a year ago, Chen Xia still can't let go, and Xin Yifan's fiancée Shu Jingyan was in a car accident, but this well-behaved, smart and considerate daughter-in-law died in that car accident, every time she thinks of Shu Jingyan, Chen Xia can't help but cry.

Shu Jingyan was Xin Yifan's college classmate, and later Xin Yifan chose the archaeology major he was interested in for his master's and doctorate, and Shu Jingyan chose linguistics, they graduated together and worked together, Xin Yifan entered the Beijing Institute of Archaeology, and Shu Jingyan stayed at the university to teach. Originally, they planned to get married at the end of that year, but who knew that the two of them were separated forever, and Xin Yifan, who survived, became like this again, and the parents of the two families could only accept this fact silently in addition to being sad.

What makes Chen Xia even more angry is that a year has passed, and the driver who caused the accident has not been caught. As sad and even guilty as they are Yu Chengdong, who is Xin Yifan's mentor and leader, the president of the Beijing Institute of Archaeology.

It all started three years ago. In the summer of 2019, Yu Chengdong led a team to discover the Xihuang site in Xiwen County, Sichuan Province, and Xin Yifan participated in this archaeological activity as Yu Chengdong's assistant. The remains of bamboo products and silk linen, the most striking is a broken crystal skull, the entire crystal skull is densely covered with runes, through the carbon 14 test, the unearthed artifacts are about 11,000 years ago, and the test results of the crystal skull are more than 45 million years ago, in order not to cause unnecessary trouble, the Beijing Ancient Research Institute did not announce the test results of the crystal skull, after all, this is too unreasonable, just sent the test results and the crystal skull directly to the higher departments, and finally this crystal skull was secretly kept and collected by the Beijing Museum, and there has been no news about any crystal skull since then。

The excavation of the Xihuang site has been carried out for more than two years, and the important cultural relics have been transported back to the Beijing Archaeological Research Institute, because most of these unearthed cultural relics need to be restored because they are too old.

It didn't take long for Yu Chengdong to receive instructions from his superiors to organize people to secretly study the runes on the crystal bones, so Yu Chengdong found Xie Ming'an, a professor of paleography at Yenching University, and asked his student Xin Yifan to also participate in this work.

Xie Ming'an is a doctor who studied in Europe and the United States in the early nineties of the last century, returned to China after completing his studies, and taught at Yenching University, she is an authority on paleography, object glyphs, cuneiform, Mayan script, seal script, linear script, etc., and is also proficient in ancient Hebrew and ancient Latin, after returning to China, she has played a great role in promoting the study of ancient Chinese characters, and she is also the teacher of Xin Yifan's fiancée Shu Jingyan.

Xie Ming'an's lover passed away many years ago, and her only son was admitted to Columbia University abroad for a master's degree in biology a few years ago, and she now has time to study with peace of mind.

Since this research work was carried out in secret, Xin Yifan got high-definition pictures of runes, Xie Ming'an quickly set up a research team to carry out research on these runes, but more than a year has passed, and they have not found the law, so Xie Ming'an proposed to let more industry experts join the research team's opinions, brainstorming, so she deliberately screened more than a dozen paleographers across the country, and applied to their superiors to let them join the research team.

After receiving the reply of agreement, Xie Ming'an decided to secretly hold a seminar in the Beijing Institute of Archaeology, and Yu Chengdong and Xin Yifan would also participate, so Yu Chengdong specially applied to bring the crystal skull to the meeting site, and the security department also strengthened security measures, Xin Yifan and Shu Jingyan were arranged to go to the Beijing Museum to get the crystal skulls.

The Beijing Research Institute is only five kilometers away from the Beijing Museum, the two of them took the explosion-proof car arranged by the special police, and there were five special police officers in the same car, bizarrely, they had a major traffic accident on the road, when the explosion-proof car passed through an intersection, a logistics truck full of goods crashed into the explosion-proof car they were riding, resulting in six deaths and one serious injury on the explosion-proof car, among the dead were Shu Jingyan and five special police. Xin Yifan was rescued, but he became a vegetative person, the driver who caused the accident escaped, and the crystal skull was missing at the same time.

The accident even alarmed the high-level, the police immediately launched a rigorous investigation, a series of investigation results made the police feel a trace of unusual meaning, the truck was originally from Jinbei Province to transport express into the capital, but the police found the driver's body in the toilet in the highway rest area, from the driver's time of death, earlier than the time of the accident; due to vehicle control, the truck could not have entered the accident site at two o'clock in the afternoon, the strange thing is that the highway crossing toll station let it swagger through, and galloped all the way, until it crashed into the explosion-proof car in which Xin Yifan and his party were riding。

From the surveillance video obtained by the police, it can be seen that the truck tried to avoid the camera-dense section of the road after getting off the highway, and there were almost no traffic police on the road, everything seemed to have been carefully planned and carefully calculated.

When the car accident happened, the driver who caused the accident was still able to get out of the truck unscathed, and quickly ran to the explosion-proof car that Xin Yifan and they were riding in, turned out the box containing the crystal skull from the car, and then quickly left, got into a car not far away and drove away, the whole process did not take more than two minutes.

The police immediately launched a follow-up investigation of the toll collector at the highway intersection and the car on which the driver caused the accident, and found that the toll collector left his post at about 3 o'clock in the afternoon of the same day under the pretext of taking leave of absence due to family affairs. Through the access to the surveillance video, it was found that the sedan actually fled in the opposite direction of the big truck when it came, and fled to Jinbei Province, the police tracked it overnight, and found the abandoned sedan on the side of a highway, and there was a deceased inside, that is, the toll collector at the highway intersection, and the abandoned sedan was a fake car modified from a scrapped car, and the parts on the car came from at least ten or more scrapped cars.

The police continued to trace the source of the scrapped vehicles, and the result was that some of these scrapped cars were scrapped ten years ago, some were scrapped five years ago, and the earliest was scrapped two years ago.

The police conducted a carpet search along both sides of the highway, but also found nothing. Later, the police investigated all the participants that day, including their nearest contacts, who did not know that the crystal skull would be transported to the site of the seminar, and Yu Chengdong did not inform the participants in advance that the crystal skull would be brought to the venue.

The entire plan for the robbery of the crystal skull was carried out seamlessly, as if it had been planned many times in advance, who did it? This question has always haunted the mind of Du Gang, deputy captain of the Beijing Criminal Police Brigade, who is responsible for the case. Du Gang has been investigating this case for a year, and he is also handling this case with Qiao Minshan, a high-achieving student who graduated from the Criminal Investigation Department of Yenching Public Security University.

A year has passed, and the task force in charge of the two has made no progress on the robbery case that caused six deaths and one injury, and they feel not only sorry for the responsibility on their shoulders, but also sorry for the deceased, including their five colleagues, which makes Du Gang and Qiao Minshan feel pressure all the time, especially when Xin Yifan's mother comes over to inquire about the progress of the case, they always feel a little guilty.

Today, Chen Xia came over again, still the same as before, sitting in Du Gang's office, Qiao Minshan poured her a cup of hot water, Chen Xia was not in a hurry but said lightly: "Captain Du, I'm really sorry, I'm here to disturb you again, I just want to ask Xin Yifan how far the traffic accident case has progressed now, it's been more than a year, when will your police solve the case?"

"Aunt Chen, you know, our bureau attaches great importance to this case, and we have also invested a lot of manpower to collect evidence, but now there is really no progress in the case, we all know the situation at your family, and we understand you very well, if there is progress in the case, we will definitely notify you as soon as possible, you really don't have to run over so troublesomely every time, you can just call me and Qiao Minshan directly if you have something." Du Gang said very kindly.

"Okay, if you don't bother me, then I won't disturb your work. After Chen Xia finished speaking, she stood up and walked directly out of Du Gang's office.

Du Gang and Qiao Minshan looked at Chen Xia's departing back, and they couldn't say anything in their hearts.
