When I came out of the airport, it was almost noon, and I called Team Cao, who were all meeting in the temporary conference room provided by the bank, and when I heard that I had arrived, Team Cao was very excited and asked me to rush to the conference room. www.biquge.info said that on the day I left, Xiao Lei rushed back from Beijing, and with him was an expert in thermal imaging technology from the army, who yesterday used some new instruments to survey the scene and made some new discoveries.

Rushed to the conference room, everyone was there, even Lao Cai and Lao Zhao were sitting at the end of the conference room, there were a lot of enlarged photos on the big conference table, and there were some light cyan spots on the black background, and I couldn't see what it was for a while. Everyone was silent, smoking cigarettes and looking at the photo in a daze.

Seeing me enter the house, everyone came to their senses, and Cao pulled a chair from his side, beckoned me to sit down, and introduced me to a middle-aged man in his early forties wearing a military uniform and glasses. It turned out that Xiao Lei had returned to Beijing to prepare a remote-controlled car and photographic equipment to enter the ventilation tunnel, and the Cao team told him about the discovery of the Xuangang Tower on the outer wall of the vault. The speaker is unintentional, the listener is intentional, Xiao Lei feels that if this tower is cast by dark iron, it should have a certain degree of radioactivity, if the thief is using the cast tower to achieve theft, the radioactive decay is slow, it should be detectable, and maybe some traces left by the thief can be found. Xiao Lei's thoughts, the Cao team didn't pay attention to them at the time, but they didn't expect Xiao Lei to really go to the National Defense University for help.

The middle-aged man in front of me is an expert in the field of thermal imaging, Professor Li Chongbin of the National Defense University, and many of the weapons and equipment of thermal imaging in our country are related to him. He shook my hand with a smile and said, "Comrade Chang, I've been looking up for a long time, Xiao Lei told me a lot of your stories along the way, I admired and was curious, and I hated to meet late." I smiled at him and asked him if he had made any important discoveries.

As soon as this question was asked, everyone fell back into the previous state of silence, Xiao Lei scratched his head, and said with a wry smile: "Our test, instead of finding the answer to the problem, has complicated the problem. I smiled and patted him on the shoulder, "The more complicated it is, the closer we are to the truth." Professor Li, tell me about it. “

"Chang, you know the principle of thermal imaging, right? I won't say more, the instrument I brought this time can not only detect the heat source, but also detect the residual radiation. Xiao Lei's judgment is right, those towers themselves have a certain amount of radiation, but the strength is not large, it should be the natural property of the material itself. Theoretically, a person who has been in contact with the tower will also have a certain amount of radiation, and he will also bring radiation to the place he has been in contact with, but the amount of radiation is smaller. As it happens, the equipment we carry is sensitive to the small differences in radiation carried by different objects. ”

"This is a picture that we took yesterday with a remote-controlled car going inside the ventilation duct, and you see, on the metal surface of the ventilation duct, the light blue dots are the residual radiation. Professor Li pointed to the photo and said to me.

After listening to Professor Li's introduction, I probably understood the working principle of this thermal imaging equipment, and the light blue dots in the ventilation duct can only indicate that the thief entered the vault through the ventilation duct, and the thief's body almost filled the entire ventilation duct in order to leave such a uniform radiation trace on the metal wall.

After listening to my understanding, Li Chongbin smiled, and then said: "Chang, your analysis is very correct, but I also saw two things that are difficult to explain. One is that, judging from these radiation points, there is obvious overlap, and there are many different shades, and I can only understand that this thief has made at least a dozen round-trips, but how can ordinary people enter that ventilation channel?

"Another suspicion is that from the radioactive traces in the vents, the amount of radiation is higher than the towers we detected later, people exposed to this radiation, a few days will all the organs will fail, it is impossible to enter and exit the ventilation duct more than a dozen times, in addition, if the tower is a radiation source, its radioactivity is not strong, will not cause much harm to people, and how thieves can receive such a large amount of radiation, this also does not make sense. ”

Without waiting for me to think about it, Li Chongbin put a few more enlarged photos in front of me, which were obviously taken at the Xuangang Tower on the outer wall of the vault, although the light was very dim, and the photos taken by the thermal imaging camera looked like the effect of a photographic negative, but if you look closely, you can still determine the angle from which he took them. In the photo, you can clearly see the four dark iron towers densely covered with light blue light spots, the light points are relatively dim, but in the open space between the four towers, there is a relatively bright light, vaguely an octagon, and the color on it has changed to light purple.

Li Chongbin pointed to the lilac spot on the photo and said to me, "Chang, I am also very surprised when the photo comes out, the strongest radiation is not the four towers, but the open space in the middle of the tower, on which there are some white bones, not much different from the surroundings." There must be something wrong with that piece of the underground. ”

"Another point, you see, all the white bones also have light blue light spots, indicating that they have also been irradiated, but these white bones are constant in their brightness and the same color regardless of how far away they are from the purple radiation circle, which can only show that the ground radiation has no effect on the white bones, or rather, these white bones were originally hung on the four Xuaniron Towers, and the radiation was relatively uniform, and then fell down at the same time and scattered all over the ground. Of course, this is just a speculation on my part. After Li Chongbin finished speaking, he leaned back in his chair and looked at me seriously.

"The white bones were originally hung on the Xuantie Tower?" I pondered Li Chongbin's words repeatedly, and suddenly had a flash of inspiration, and turned out the notebook, last night, when I was not very awake in the second half of the night, I copied a lot of notes from the ancestor Chang Jilin in the family tree, I didn't know what it was to use at all, but after surviving the long cold night, I only remembered it now, as if there were important hints in the notes.

I flipped out my notebook, looked at it page by page, and stopped talking.

"Shu religion is mixed, witch religion is one, Maitreya has been in Shu for a long time, respect the fish for the source, take the bronze cast cash tree and the ancient iron tower as the holy object, sacrifice it at the end of the month at the beginning of the month, called the tree sacrifice and the ancient sacrifice, when the congregation is prosperous, taste the same sacrifice of 10,000 people, say the incense of all beings. The ancient sacrifices of the tree are not shown to people with holy objects, and they are replaced by wooden carvings, and they do not know their existence. When transcribing this paragraph, I also had doubts about the "ancient" sacrifice that the ancestors said, and it could not correspond to the "tree" sacrifice, but now that I think about it, the ancestors did not personally see it, whether they mistook the bone sacrifice for the ancient sacrifice.

If this is really the case, then Maitreya is inextricably linked to the ancient Shu civilization that has disappeared. I know the story of the bronze money tree, Sanxingdui, Guanghan, Sichuan Province has unearthed a tree, more than four meters high, several tons of weight, the tree is full of copper coins, very spectacular. There was also a larger one, which was unearthed in Hanzhong, but it was stolen and dug up. Tomb robbers cut the bronze tree into small pieces, smuggled them out of the country, and then re-welded them abroad, and appeared at auction a few years ago, which was a sensational event.

But Feng Wei, an antique player in Beijing, once told me that legend has it that when the tomb robbers entered the tomb, the bronze tree stood in the middle of the tomb, like a dead tree, with no copper coins or other decorations on it. Because it was too bulky to carry, the tomb robbers carried out the things that were easy to carry, and the next day they prepared some tools to dismantle the tree and transport it out, and a group of people touched it again.

When entering the cave, the tomb robber felt a slight tremor on the ground, thought it was an earthquake, and wanted to run out, but after waiting for a while, there was no movement, and then he entered the tomb again. After entering, the tomb robbers were shocked to find that the bronze tree was full of copper coins, and a thick layer was laid, and the key was to be new and new. They remember that when they came in yesterday, there were copper coins scattered on the ground, but not as many as they are now, and there was a layer of dust attached to them. Where did these new copper coins come from? Did anyone else enter after them?

What makes the tomb robbers even more incomprehensible is that the copper coins on the ground are all in the Song Dynasty, how did the copper coins of the Song Dynasty run into a tomb in the Qin and Han dynasties?

When the tomb robbers saw the new money in this place, they were already chilled, and they were unwilling to give up the windfall in their hands, so they were bold, burned incense and worshipped, sawed the bronze tree into a few sections, and smuggled it out, but none of the copper coins on the ground dared to touch it. Later, the story of this group of people gradually spread, and some seniors in the collecting industry said that according to legend, there was a bronze cash cow in ancient times, not that some copper coins were hung on the tree as decoration, but that they could really shake the money out of thin air, but no one seemed to have seen it with their own eyes, let alone know the principle.

There are still some legends about the tree sacrifice, but the ancient sacrifice or bone sacrifice is really unheard of, is it really Li Chongbin's saying that the white bones are hung on the Xuantie Tower? What is the purpose of doing this? I briefly told you the contents of the notebook, and obviously, on these issues, everyone is more confused than me.

It's useless to think about it, I still ask Team Cao to set off for Langzhong immediately, we need to thoroughly understand Chef Fang's line, as for the new mysteries that continue to appear on the scene, let Professor Li and Xiao Lei study them first.

(In the past, people said that those who knew the way of immortality would be accepted by Yan Jun, and those who were not quick would die.) Yan Jun is very angry, and his messenger will punish him. Xingchen advised: "Those who are worried about others should not be in a hurry to die, and those who are heavy to themselves should not be in a hurry to live." He lost his life, can An make the king not die?" There are Qi Zi who also want to learn his way, and the death of the one who hears it is soothed and hated. Fu Zi laughed when he heard it and said: "What the husband wants to learn will not die, but his person is dead and hates it, so he doesn't know why he learns." The beard said: "The words of the rich son are not true." Mortals have skills that cannot be done, and there are those who can do but do not have skills. There are good numbers of guards, and when they are dying, they use the trick as a metaphor for their sons. His son is determined to do what he says, but cannot do it. When others ask, tell them what their father has said. The questioner does what he says and does what he does, and he is no different from his father. If so, the deceased is ridiculed as not being able to speak for life?" -- "Liezi") (To be continued. )
