Looking at the human figure on the ground, Liu, the big hand frowned and thought for a while, then pointed out the positions of each Duan Zhenwen on the human body one by one. Squatting beside the human figure, Old Liu and Zhang Guozhong stared at each other with big eyes and thought for a long time, but they didn't know why. "By the way, Yicheng, where is the small cave you mentioned?" Zhang Guozhong asked.

"If I knew where I was, it wouldn't be lost..." Zhang Yicheng was timid.

"I know, I'll take you there!" Big Hand Liu tightened the hemp rope around his waist and was about to set off.

"Brother Liu... Let's talk about it again in the sky... Let's talk about it again in the sky..." Old Liu hurriedly grabbed Dashou Liu. At this time, Cui Liyan came in from outside. When he saw Cui Liyan, Dashou Liu immediately forgot about taking people to the small cave. He jumped forward and grabbed Cui Liyan's wrist. The speed was even more exaggerated than the real "Thousand Souls Owl". "That ghost looks like him!" Before Cui Liyan could react, Dashou Liu had already "better to mouth first", "But a bigger mouth...the eyebrows are thicker than him..." The words just now were not bad again. Cui Liyan also admitted his head. In order to avoid this matter, he ran outside the cave and blew the mountain wind for half an hour, but he still couldn't escape the disaster...

The next morning, just dawn, Liu led everyone to the small cave in Zhang Yicheng that was in danger. Zhang Yicheng almost died of anger. It turned out that this small cave was only a few hundred meters away from the camping cave. It took him ten minutes to walk from the hillside. He only made a few bends around the hill. Although he walked for more than forty minutes last night when he was looking for a kite himself, most of his kung fu was circled around the valley.

"This hole... was blown out..." In the small cave, Comrade Elxun, a blasting expert, carefully observed the broken rock walls in the cave, and pulled out a few cubes of broken soil from the cracks and smelled it with his nose. "The explosion is very professional, and it is not ordinary exploration detonators, but professional military explosives!"

"How long has this hole been here?" After hearing Alxun say this, Zhang Guozhong turned to ask Liu.

"I don't know, I didn't have it before, but it happened later!" Liu Dao, the big-handed.

"Do you still remember when?"

"I don't come here very much! I found that the two dead people seemed to have already... I hadn't been here for a year before."

"It's weird..." When he heard the two dead people from Dashou Liu talk about, Zhang Guozhong subconsciously linked the cave to the death of the Liao couple, "Why do you want to blow up a cave? Do you want to hide the body? It's unreasonable..."

"That's it! That thing came out of here, and I wanted to drag me into it too!" Zhang Yicheng shouted at a cave in the corner of the small cave.

After approaching, a few people surrounded the hole and observed it. It was a hole with a special shape, which was probably a trapezoidal shape. It was wide at the top and narrow at the bottom. It was diagonally penetrated from the corner of the cave. The diameter of the hole was about 60 or 70 centimeters. I shone it into the hole with a flashlight and found that although the angle of the hole was steep, it was not very deep. The angle at the end of the hole seemed to have changed from a steep slope to a horizontal, so dark that I didn't know where it reached.

"Just live here?" Cui Liyan's tone seemed to have some jokes. In his impression, ghosts were all invisible, so why did they dig holes like rabbits at this time?

"This... seems like a thief..." Sun Ting touched the hole wall with his hand, then glanced at the hole entrance and observed the angle, "It's so professional!"

"Risk the hole?" Zhang Guozhong and Lao Liu frowned at the same time. The hole must have been dug by the tomb robbers. There are no ancient tombs in the wilderness. Who is so full that he runs here to dig the hole?

"It is difficult to dig holes on the mountain, or it is much larger in plain areas, so this hole is quadrilateral..." Sun Ting continued to analyze, "Compared with circular holes, four-sided caves are more labor-saving, and the area to be dug is smaller, and the angle of inclination should be the maximum extent that people can climb without using external forces. I don't understand why they dig holes after exploding a small cave here, but one thing is certain, these people do not seem to be traditional tomb robbers..." Sun Ting reached out and touched the smooth and flat wall of the ground hole. "Not only did they use military explosives to blow up the cave, I suspect that this hole also comes from some more modern equipment, and it can even be said to be scientific research-level equipment!"

"Do you know archaeology?" Hearing this, Cui Liyan seemed to be very curious, "Do you see there are ancient tombs in this mountain?"

"It's hard to say..." Sun Ting shook his head, "In Chinese history, the only dynasty that prevailed in the Tang Dynasty. The tomb construction projects in the mountains were huge, so only high-ranking officials could build them. The tomb sites they chose were often famous mountains and rivers, so it is unlikely that they would choose to build tombs like this kind of low mountain..."

"It makes sense!" Old Liu said, "Even if you build a tomb in the mountains, you have to look at Feng Shui. Feng Shui here is bullshit. If you have yang but no yang, there will be yin and no yin. No matter how rich you have, you can't do such a thankless thing!"

"Since there is no tomb, what will they do when they go down?" Cui Liyan asked.

"I don't know..." Sun Ting compared the diameter of the hole and his waist with his hand. "But one thing is certain that what they want must not be a big piece... With the diameter of this hole, it is difficult to get a slightly larger thing..."

Zhang Guozhong kept illuminating the hole with a flashlight. After hearing what Sun Ting said, he suddenly remembered that he had gone to Bashan to find the imperial seal. At this time, he heard that there were small items hidden inside. In addition, he always felt that the cave was related to the death of the Liao couple, and his curiosity also came up, "Is there a rope? I'll go down and take a look..."

"I have a rope!" When Dashou Liu heard Zhang Guozhong ask if there was a rope, he immediately untied the hemp rope at his waist. The rope was not thick, similar to his fingers, but it was still okay to bear the impact of a person. Although Dashou Liu had wrapped around his waist, it seemed like he had not been able to pull it for a few times, but it was untied as much as seven or eight meters long.

In order to save the rope, Zhang Guozhong simply tied the rope head to his belt, pulled out the "Tianlu" with his trouser legs, and drilled into the hole with his waist. "Dad, there is something inside, please be careful!" Zhang Yicheng seemed a little worried.

"It should be nothing to do in broad daylight..." Old Liu was not worried. Although Liu was very strong, he was a human being after all. He could not beat people's grievances in the middle of the night. How capable could he have during the day?

After drilling into the hole, Zhang Guozhong really regretted eating wildly at Sun Ting's house a few days ago. His waist was thicker. It was a bit difficult to drill this hole. Fortunately, the slope of the hole was really as Sun Ting said, with a bit ergonomic meaning. He slid his head down and pressed the wall of the hole hard, and he felt that he could still eat hard.

It was more than one meter away from the bottom of the hole. The rope was over. Zhang Guozhong felt itchy. Unlock the rope and continue moving forward. The hole was too narrow and couldn't turn around. It was too difficult to rub it backwards. Now let someone pull himself back, and then want to see what it was underneath. "Damn it, if you don't enter the tiger's den, how can you get a tiger! Maybe the answer to the Liao family's murder case is below..." After comforting himself, Zhang Guozhong untied the rope tied to the belt, "The rope is over! I'll go down and take a look, the rope head will stay here, don't pull it up!" After a few throats in the back of the crotch, Zhang Guozhong began to continue crawling down.

When it reached the smooth part of the bottom of the cave, Zhang Guozhong was stunned. The horizontal hole was dug at most two meters long, and then it opened to a natural small stone cave that was one and a half meters square and nearly 80 cm high. It was not only enough for normal people to turn around, but it was even a problem of lying here with their legs curled up and lying here for a sleep. From the walls of the cave around the space, it seemed to be completely natural. Go forward in the direction down. In front of the small stone cave, a black hole was passed vertically and shone down with a flashlight. It was definitely bottomless. "It seems that this is a transit station..." Zhang Guozhong picked up a stone and threw it down the hole, but he didn't hear any movement. "It's so damn deep..."

Seeing Zhang Guozhong head down, and now head up, everyone present was very surprised, "Dad, have you practiced acrobatics?" Zhang Yicheng couldn't help but ask, "How did you twist your body?"

"There is an empty hall below!" After drilling out of the thief hole, Zhang Guozhong patted the soil on his body, "I know why they had to explode a cave here and dig it, just for the empty hall below!"

"What an empty hall?" Sun Ting was stunned.

"The natural stone cave in the mountain is probably so wide and square, so high..." Zhang Guozhong gestured with his hand, "Also, there is a vertical thief hole on the edge of the stone cave, which is bottomless! I wondered how they knew that there was an empty hall in the mountain! The digging was too accurate! If you dig a vertical thief hole, that empty hall could be a transfer station!"

"Can Feng Shui see that there are stone caves in the mountains?" Sun Ting asked.

"Yes!" Old Liu headed firmly, "but the hole as small as Guozhong's gesture could not be seen!"

"That's it..." Sun Ting thought about it again, "They not only have advanced drilling equipment, but also advanced exploration equipment! These are definitely not ordinary tomb robbers! Their purpose must be not ordinary!"

"I think so!" Zhang Guozhong said, "There are all whole pieces of rocks or gravel in the mountains. Generally, people who rob tombs must dig to death with a Luoyang shovel. It is not a job that humans can do at all! Especially the vertical thief hole below!"

"Several people, we have to hurry up! The driver can't wait long!" Although he was quite curious at first, Cui Liyan was no longer interested when he heard this. After all, he was a forensic doctor. "It will take less than a day or two to go back...!"

Lintan County, in the hotel.

After returning home, Zhang Guozhong's first thing was to change his pants, and Lao Liu took out his cell phone and dialed Liao Ruoyuan's phone. After learning that Lao Liu and his party did not find any key clues, Liao Ruoyuan's tone was somewhat disappointed. When he learned that Lao Liu wanted to know his parents' motivation to come to the mainland, Liao Ruoyuan seemed extremely embarrassed. "Mr. Liu, I asked my aunt about this a long time ago, but she refused to say it! She is a very stubborn person, and I know her!"

"She knows so!" Old Liu asked.

"It seems, but I'm not sure. Every time I ask about this, she's very upset! Without saying a word, I don't know if she really knows it!"

"In this way, Master Liao, please find a way to ask her! Let's think of a way here, how is your wife doing?"

"She hasn't found the forensic doctor yet. I will notify you as soon as possible if she finds it!"

When he hung up the phone, Old Liu was overwhelmed and thought to himself, what kind of sister is this? His sister died inexplicably, why didn’t he tell the truth? "Guozhong, do you think that thief has anything to do with the death of the couple?"

"It's hard to say!" Zhang Guozhong said, "I think it may be a bit related. At least the things that came out of the hole were the same as the corpse of the couple, with words on them!"

"Or..., let's go down and take a look?" Old Liu was also a little curious. If it was really like Sun Ting said that the person digging the hole was a group of scientists who knew how to use advanced equipment, what would be hidden in the hole? And who were those scientists?

"I'm afraid it won't work now..." Old Liu said as soon as he thought about going down, Sun Ting entered the house with a glass of water. "We only have flashlights on our bodies and don't have any equipment. It's very dangerous to go down..."

"Equipment?" After hearing Sun Ting's words, Old Liu smiled and pulled out the Seven-Star Sword with a cry, "This is the Equipment..."
