When the elevator reached the top of the stone pillar again, Professor Chen took a flashlight and carefully took a photo from the edge of the stone pillar and found that the artificial chisel marks mentioned by Zhang Gong were indeed very obvious, and although the stone pillar had experienced so many years of slow growth, the chisel marks of the year were still clearly visible on it. The middle part of the pillar is sunken and covered with black-green moss.

Ma Kai asked while taking pictures: "Professor, doesn't moss need light to grow, and it is dark after being closed here, how does it exist?" ”

"Isn't there a hole in the east that is still open, and the scattered light is enough for them to multiply."

"And what's under the moss?"

"Anything is possible, now I'll go and see, don't move."

With that, Professor Chen prepared to step over the guardrail on the elevator and into the stone pillars. The firefighters around him quickly stopped Professor Chen's dangerous move, and said solemnly after helping Professor Chen: "This is too dangerous!" You can't step out of here, tell me if you have any ideas, and I'll do it for you! ”

Professor Chen felt the obviously shaky guardrail, looked down again, and felt that it was indeed a bit dangerous, so he said to the firefighter: "Then you can help me to shovel out a small piece of moss in the middle, and then see what is under the moss." ”

The firefighter carefully stepped onto the stone pillar, took the shovel handed by Professor Chen, walked gently to the middle and shoveled a piece of moss, and knocked it with the shovel in Professor Chen's continued signal. Subsequently, with the help of the fire fighters, Professor Chen went to the top of the stone pillar on the place where Zhang Gong said, and saw that the middle was all uneven moss, Professor Chen guessed the result without going over, and it was estimated that the things under the moss were the same gold and silver burial goods as Zhang Gong said.

After sending off the firefighters, they held a small meeting, and the results of the study agreed that the gold and silver treasures in the middle of the stone pillars on the south side should be brought out first, so as not to have too many dreams at night.

After reporting the findings here, Professor Chen arranged for Chen Zhijun to pull a steady stream of steel pipes and fasteners from their construction site, and while piling up the materials in the open space below the cave entrance, he also began to build scaffolding around the stone pillars in the south of the cave.

During the slow construction of the scaffolding, Professor Chen and the others studied the map in the copper box in the general's tomb, and Zhang Gong believed that the holes on it were not bitten or damaged by insects, but were artificially trying to reveal some information through these, and that information should also be related to gossip, and the hexagram may also hint at some direction. Although there is a direction for analysis, there is too little information that can be provided above, and all speculations are untenable before the mystery on it is truly solved, and several people have returned to the initial confusion after discussing it for a long time.

In the afternoon of the next day, I saw that the scaffolding was almost on the top of the stone pillar, and it would definitely be completed in more than an hour, but the sky was not beautiful, accompanied by lightning and thunder, and suddenly it began to pour down. In order to ensure safety, Professor Chen instructed the old horses to stop what they were doing and stop carrying steel pipes into the cave.

The rain in the mountains lasted for several hours at a time, and by the time the rain stopped, it was already past 8 o'clock in the evening. After discussing the work plan for tomorrow for a while, everyone fell asleep.

In a daze, Zhang Gong was awakened by a muffled sound of "bang". When I opened my eyes and saw that there was no rain or thunder outside, I chuckled in my heart, and quickly got out of bed to wake up Professor Chen in a daze and shouted outside: "Be careful, someone blew up the tomb!" ”

At the same time as Zhang Gong shouted, the armed police and public security in the opposite tent had all rushed into the cave. In the brightly lit cavern, a rope hung from the hole above the east side, and a hole the size of a man was blown open with explosives at the foot of the stone pillar where the coffin might have been hidden, and nothing was found except for a piece of brown paper, which might have been used to wrap a detonator.

When Zhang Gong saw the hole that was blown out, he scolded angrily: "Damn, this is a robbery!" ”

Seeing this, Officer Wu, who led the team, hurriedly walked up to Professor Chen and asked, "Professor, what's down there, this person has a very clear purpose, he is here there." ”

"What could be a bronze artifact below, we don't know what it is."

Zhu Gong lay at the entrance of the cave and put the flashlight into the water, and then leaned into the water and said: "This is very wide below, and the water level difference between this and the lake below is more than 20 meters, which means that it is not directly connected to the outside, if this water has an outlet, then the thief just now will definitely not go down from here, as soon as there is an explosion, we will come, it is not a minute in between, it is impossible to get out of the hole, and it is even more impossible to go out from the top, the only explanation is that the person is hiding in this water, There might be a hole in the water for him to hide! ”

Listening to Zhu Gong's analysis, Professor Chen hurriedly instructed Zhang Gong: "Lao Zhang, quickly take a three-dimensional imager to see where this underground river leads; Take the metal detector and see if what's down there is still there, and if not, if it's gone, see if it's moved somewhere else. ”

After the panicked arrangement, Zhang Gong and Ma Kai ran to the tent to get instruments and tools, and soon used instruments to detect the perimeter of the explosion point, but after detection, it was found that the original metal reflection signal below disappeared, that is, the things below were lost.

After scanning with a 3D imager, it was found that the underwater water was intricate, with multiple dark holes underwater, and all of them were open, all the way to the boundary of the cave.

At the same time, the comrades of the armed police also took off their uniforms and carried waterproof flashlights to dive underwater to conduct a general search, but they found nothing.

When Zhang Gong and two police officers ran to the hole on the east side of the cave, they found that in addition to a series of obvious footprints, an empty backpack containing something was thrown on the side. Later, after inspecting several detectors outside the cave, it was found that the connecting wires of these detectors were all scrapped in the afternoon wind, and they became decorations one by one. However, the camera installed in the cave clearly recorded the scene just now: a middle-aged man wearing an exaggerated mask in the game and wearing a diving suit descended from the top of the cave to the bottom, and went directly to the east under the stone pillar to detect the bottom with a portable metal detector, and after finding the right place, he installed a detonator, placed explosives, and dived directly into the hole after the explosion, all the actions were done in one go, and the total time was only 1 minute and 37 seconds.

After watching the monitoring replay, Officer Wu said: "Professor, it seems that this is a premeditated professional thief, this person's goal is very clear, his actions are very neat and professional, it is estimated that he has detected this a few days earlier, and also predicted the direction of the underground river, it should be out of this cave, now we will report to the bureau, apply for the police to search the mountain, there is no other way." ”

After speaking, Officer Wu gave a report to the city bureau, and then arranged for the existing police force to work in groups of three to start searching in two directions along the road below.
