"These abrasion marks seem to be their own. and as if they were connected to one another, and ...... And there are always abrasion marks on one side and none on the other, always alternating, but there is no place where there are abrasion marks on both sides at the same time. ”

Yang Huiling's eyes were sharp-eyed and careful, and she was the first to summarize the characteristics of the ground abrasion marks, and after listening to her, Yang Jianqiang and the others nodded in agreement.

"Little Nizi has good eyesight!" Meng Lao also smiled approvingly at Yang Huiling.

"But what does that mean?"

Yang Jianqiang took a deep breath and squatted down. He touched the side of the ground with serious friction marks and said.

After Meng Lao stood up, he shone his flashlight at his feet again and asked us: "If you see the road in front of you like this, will you subconsciously choose to take that leg?" ”

Looking at the light of his flashlight, perhaps because of the reflection on the ground, I saw that one side with abrasion marks was obviously pitted, and the other side was very light. Slippery.

"Step on your left leg! That...... That's this way, of course! ”

Han Jianjian pointed to the bright side and replied casually.

Meng Lao nodded slightly, took another step forward, shone his flashlight on the ground again, and asked us, "What about this time!" ”

Han Jianjian pointed without hesitation: "Of course it's here!" ”

Meng Lao looked around at us with a smile of victory, and said lightly: "Understood at this moment?" ”

I thought to myself, what do you understand! What the hell is this time, and he still talks in a crepe-like manner.

"I see!" First, Xue Chuanqiang exclaimed.

"I see!" After that, Liu Liwei shouted loudly.

Han Jianjian scratched his scalp and looked at them, then looked down at the ground, still confused.

"It turns out that we have unknowingly fallen into the trap of the Dongyi clan!" Yang Jianqiang also clapped his hands and shouted excitedly.

"What's wrong here!" Han Jianli still didn't understand.

At this time, it was like a lightning bolt in my mind, and it suddenly dawned on me, so it was like this!

Since going down to the bottom of the pit, there are similar abrasion marks on the ground where we have passed, I have seen it before, but I didn't care, I only understood when I was so touched by Meng Lao. The underground space is in the dark all year round, so the people who come in must need lighting equipment, ancient people must have used torches, and now people use flashlights. When the light hits the ground, depending on the pattern, it will show different reflective effects, and the side with abrasion marks looks uneven, and we subconsciously do not want to step on it, but step towards the other side.

I thought the road I walked in this way was a straight line, but it was not a straight line, but I was "led by the nose" by the abrasion marks on the ground.

Just imagine, if we can't find out this secret, we are likely to be trapped in this big pit.

Now that you know this secret, it's easy to get out there.

Everyone returned to the question just now: Professor Song!

"Old Song must have something to hide from us! Instead of waiting for him here, we should wait at the altar first. ”

Ma Huadong said.

"That's fine! Don't look at the pattern under your feet again this time! ”

This time it took less than five minutes, the "gold" shaped "stone mound" and piles of white bones appeared in front of us, what I didn't expect was that Wu Jinghan and Yang Huiling didn't feel scared at all, I thought about it, the two of them are graduate students majoring in archaeology, and those who study archaeology are afraid of bones, so wouldn't it be in vain?

"Old Ma, the Dongyi Clan's Rebirth Festival sacrifice activities, need to kill so many people?" Teacher Wu asked Ma Huadong.

Ma Huadong shook his head: "I don't know about this, this Dongyi clan's sect. Teaching is almost unknown to us! However, the sacrifice of the Shang Dynasty was very bloody, and when the average small slave owner worshiped his ancestors, he would also kill more than a dozen slaves at a time. ”

Teacher Wu smiled slightly: "I also know this!" ”

Yang Jianqiang and Liu Liwei only glanced at the white bones, and their eyes were fixed on the "stone mound", and Han Jianli and I also swept away with their gaze, while Teacher Wu and his two students seemed to be more interested in the white bones around them.

"This should be a Dongyi altar!"

Meng Lao pointed to the stone mound and said.

After what happened just now, I looked at the scrawny old man in front of me differently, and I believed what he said from the bottom of my heart.

The altar is made of basalt, about three meters high, conical in shape, but the top is also four or five square meters in size, and I followed them around the altar in a half circle, and found that there was a stone step on the other side that led to the top of the altar.

Teacher Wu on one side was whispering to the two beauties.

"The bones are fossilized and are estimated to have died for at least 3,000 years."

"Most of the skeleton's hands are behind their backs, and they should have been tied behind their backs before they died, but the ropes had rotted away after too long."

"Almost all bones have obvious chop marks on the neck, which should be beheaded......"

Teacher Wu said that Wu Jinghan and Yang Huiling were still holding notebooks and writing them down carefully.

"Brother Dong, look! There's a picture carved into this stone! ”

I was looking at Wu Jinghan stunned, when I heard Han Jianjian behind me exclaim.

"What's the portrayal! What's all the fuss. ”

As he spoke, the man walked up behind him.

The side of the altar is carved with a number of paintings, most of which are still quite clear.

Perhaps hearing Han Jianjian's shout, Teacher Wu and the others also came over.

"Oh my God! This is...... It's a narrative mural! Teacher Wu behind him stared at the portrayal for a few seconds, and then suddenly shouted loudly with a trembling voice.

"What? What's the matter, Mom? Han Jianli didn't hear clearly, and asked rhetorically.

Yang Huiling gave him a blank look and explained: "It's a narrative mural. This is the period of primitive society, in the absence of words, in order to remember some particularly important things, human beings at that time carved these things in the form of paintings on the stone, which is the narrative mural. ”

I don't know if Han Jianjian really understands or fakes, so after nodding, he looked at Shibi again.

Yang Huiling took out his camera and quickly took pictures of the mural.

"Teacher, it seems that the painting on it is a scene of hunting by the ancients?" Wu Jinghan pointed to one place and said.

Teacher Wu nodded, but in less than three seconds, he shook his head again: "It doesn't seem to be so simple, look here!" ”

Following his fingers, he saw several small figures painted on the mural, one of whom was only half a body, and the others surrounded him, bending slightly.

"What is this doing?" After Yang Huiling put down her mobile phone, she leaned over to Mr. Wu's side and asked in surprise.

"It looks like these people have found something!" After taking a deep breath, Mr. Wu continued, "This person is only half of his body, but he is a living person, is it ...... Is the other half in the dirt? ”

After finishing speaking, perhaps he also felt that such an assumption was a bit ridiculous, and shook his head with a wry smile.

"Teacher, could the lower half of his body be in a hole, and the people around him are not looking at this person, but at him. What about the lower holes? ”

Teacher Wu nodded: "Makes sense!" ”

With that, he moved to the next rock.

The mural on this stone was so badly damaged that it was only vaguely discernible that seven or eight people were bent over and walking!

"Why do you have to walk with a bent over?" Teacher Wu muttered!

Han Jianli replied casually: "Then you must not be able to straighten your waist!" ”

These words provoked the three masters and apprentices to look at him with six pairs of eyes.

"What? I...... I said it casually, too! Han Jianli was suddenly stared at by the three of them, and he was a little helpless.

"I know! These people must have been walking in a cave – or rather a tunnel – that was shorter than them. ”

Mr. Wu's words were almost shouted, he excitedly stepped to the next stone, glanced at it, and pointed to a place in the mural: "Look here, these people are holding one hand, and there is a vertical line in their hands - it should be a wooden stick, no!" It's a torch! It's a torch! ”

Teacher Wu actually clapped his hands and jumped, like a five or six-year-old child.

"Teacher Wu, are you alright?"

Han Jianjian grabbed Mr. Wu's arm and asked in surprise.

"Boy? You...... Do you know what this mural says? Teacher Wu grinned and asked Han Jianli.

"Your professor doesn't know, how can I know!"

"Nonsense! Who says I don't know? These murals are about the process of the ancestors of the Dongyi tribe discovering this underground space, and sure enough! They entered the underground space through a crack in the ground! ”

As soon as Han Jianli opened his mouth, before he could speak, he heard Yang Jianqiang on the other side shouting, "Come and see!" Over here...... There's a dead man here!"

This is actually a very strange phenomenon, the same animal, people eat the meat of most other animals very calmly, and see the pig or dog that has been split in half, most people do not feel too much discomfort in their hearts, but if you suddenly see a dead person on the road, it is estimated that most of them will be scared enough, and they don't even need to look, just hearing that there is a corpse in front of them, their hearts will tremble.

A thought quickly flashed through my mind, he said that it was a dead man, and he probably didn't mean a skeleton, because there were thousands of skeletons around here, and there was no need for Kenben to make a fuss.

A few people turned around, only to find that Yang Jianqiang, Liu Liwei and the three special police officers had arrived at the altar.

"What dead man?" We hurriedly went up the stairs to the altar, and before Mr. Wu arrived, he asked excitedly.

I thought it was an ancient corpse, but it was far away through Liu Liweishuang. In the gap between my legs, I saw the person lying on the ground wearing a dark camouflage uniform, and it was similar to the one on our body, and my heart fluttered at a glance.

"This ...... Who is this? ”

Teacher Wu asked again.

The corpse was face down, looking at the clothes on its body, it had decomposed in a large area, and it was also a pity that in such a space, there was no wind and no rain, and the corpse gradually became a dry corpse.

"I don't know! I guess the person who entered the underground space before! ”

Professor Gu coughed, and the two SWAT officers reacted quickly, and hurriedly made way for him.

After Professor Gu put on his white gloves, he squatted lightly in front of the corpse, and I remembered this moment, yes! Professor Gu is Liu Xili's mentor, and he should be a more powerful forensic doctor, and with him, he should be able to see some clues from the corpse.

"He had been dead for at least ten years, if not longer, and was a middle-aged man whose flesh had dried up...... It's been too long, and I'm afraid I won't be able to get more information without the help of professional equipment. ”

"Could it be that apart from Lao Song and their group, there are still people who have been to this underground space?" Teacher Wu wondered.

Yang Jianqiang nodded: "As far as we know, the team that has entered here plus us is at least three batches, so I'm not surprised by this." ”

"Oh? So what's so weird? Professor Gu asked.

"His clothes!" Yang Jianqiang replied categorically.

"That's right! The clothes he wears are similar to ours! ”

Han Jianjian muttered.

Before setting off from the water conservancy station, Yang Jianqiang asked us to change all into uniform camouflage uniforms, saying that this kind of clothing is somewhat special, very solid, and very tight, and the general dagger capital is impenetrable, and it is fireproof and waterproof, and it is the latest outdoor camouflage suit for special police.

"We can't buy this dress outside for any amount of money, because there is nowhere to sell it." Yang Jianqiang pointed to the clothes on the dried corpse on the ground again, "This set of clothes is the old model of our clothes, if I am not mistaken, it has been replaced fifteen years ago, and it has been used for a total of seven or eight years!" ”

Yang Huiling reacted quickly and immediately replied: "Does Team Leader Yang mean that this dry corpse should have entered the underground in the seven or eight years between fifteen and twenty-three years ago?" ”

Yang Jianqiang nodded.

"Could it be one of Lao Song's group of people?" Teacher Wu exclaimed.

"I guess so! There were so many of them at that time, although only Professor Song and Li Guozhi got out alive, but this does not mean that the others died at that time, perhaps...... Maybe one of them fled at the time, and then the ghost sent a god to die here! ”

As soon as Yang Jianqiang finished speaking, we all nodded in agreement.

"I want to know what this handsome guy looks like, why did he die on the altar? Do you want to ascend to heaven? Han Jianjian muttered quietly.

These words seemed to remind Yang Jianqiang, he glanced at Han Jianjian, and then turned around and asked the two special police officers to turn over the body of the dried corpse on the ground.

"I don't see what it looks like! It's all a dry corpse!! Wu Jinghan muttered.

The corpse was turned over, and I saw a hideous face. I remember watching the archaeological documentary of the ancient kingdom of Loulan, and the corpse found in the desert was like this, but there was another familiarity, as if I had seen this person there.

I can't have seen it! He's been dead for almost twenty years, and I'm only how old I am then! It should be an illusion.

"Team Leader Yang, Liu Suo, maybe he has a document in his pocket that can prove his identity!" The tall SWAT reminded.

"That's right! Hurry up and flip through it! ”

Two SWAT officers cautiously stretched out their hands. Entering the pocket of the dried corpse's clothes, he found two small black notebooks from the inner pocket of his jacket, slightly larger than his ID card, the leather had changed color, and the surface was covered with small brown particles, but he could vaguely see the dark lines of the Great Wall on it.

"This is a work permit!"

As soon as the small notebook was taken out, Teacher Wu on the side immediately exclaimed.

"What work permit? You...... You say it's a work permit? Yang Jianqiang looked puzzled.
