That is, there should be no roaring in this place at all!

"There's a secret passage on the flat ground?" Song Shaofeng frowned, pointed to the platform, and speculated.

Lin Ling shook his head and denied, "No." ”

"Let's see." Song Shaofeng didn't dare to make up his mind.

Several people continued to be vigilant as they climbed to the top of the mountain.

The bones on the top of the mountain are relatively large, and it can be determined that they are not human bones, which makes everyone a little relieved.

Zhao Xuan cautiously bypassed the bones on the ground and glanced around.

"It's beef bones, fresh." Zhang Yuan stirred the bones on the ground with the sword in his hand.

"Can you tell what animal is eating?" Song Shaofeng turned his head and looked at Zhang Yuan.

"Fortunately, the young master is wise, and he thought of it from the moment he heard about the cow." Zhang Yuan waved the sword in his hand, and the long sword shook slightly, easily inserting it into the dirt.

"See? What is a profession? As he spoke, he took out a pair of rubber gloves from his pocket, and waved them proudly at a few people, and then put them on.

"From the tooth marks, it doesn't look like a large carnivore." Zhang Yuan picked up a piece of cow bone, flipped it up and down, and analyzed: "There are no traces of scavengers, which means that the gnawing is very clean." ”

"You still know this?" Zhao Xuan listened to Zhang Yuan's analysis on the side and couldn't help but ask.

Zhang Yuan said proudly: "That's!" The master is from the Department of Archaeology. ”

"The Department of Archaeology still studies this?"

"Don't learn."

"Then you talk."

"Don't interrupt and get down to business." Zhang Yuan found that he was pretending to be crooked, so he immediately stopped the topic and complained to Zhao Xuanlai: "I forgot to analyze it." ”

This kind of tense moment means that Zhang Yuan and Zhao Xuan can chat.

Zhang Yuan continued to turn over the bones in his hand in a serious manner, and Lin Ling, who was not far away, interrupted: "This way! ”

Zhao Xuan gave up observing Zhang Yuan's movements and leaned towards Lin Ling.

When he got closer, he saw Lin Ling cleaning up the grass and trees on the ground, and among the grass, there was a complete corpse.

To put it all right, it is relative to the bones of cattle scattered all over the place.

The corpse was lying on its head on the ground, dressed in camouflage uniform, but it had almost become strips of cloth.

The body was full of wounds, large and small, and an arm was twisted behind him at an exaggerated angle.

"I'm pretty sure it was a human thing." Zhang Yuan walked over while saying the conclusion, saw several people standing there, and asked, "What's wrong?" ”

"Wow!" Zhang Yuan finally saw the corpse on the ground, and said with an exaggerated expression: "The spoils are unevenly divided." ”

No one paid attention to Zhang Yuan's cold jokes.

"It can be determined that what Chen Degui said is true." Song Shaofeng pointed to the corpse on the ground: "Zhang Yuan, go and check it." ”

"Why me?"

"Because you were prescient and brought gloves." Zhao Xuan pushed Zhang Yuan behind him.

Zhang Yuan glared back at Zhao Xuan, stepped forward, bent down, and carefully turned the body over.

Sure enough, as Chen Degui said, the corpse's face was old, his hair had all fallen out, his skin was hanging loosely on his body, and his face was as thin as a skeleton.

Song Shaofeng clasped his hands, looked at it for a while, and said loudly: "Look at the teeth." ”

Zhang Yuan nodded, reaching out and lifting the corpse's lips. A full set of teeth is exposed.

"This ...... What's going on? No matter how proficient Zhao Xuan is, he also knows that this tooth and face definitely don't match.

"I don't know." Song Shaofeng shook his head and continued: "Look at the pockets of your clothes. ”

"What about calling the silly boy?" Zhang Yuan muttered unhappily, but his hands didn't stop, rummaging through the corpse's tattered clothes.

Zhang Yuan finally found a ziplock bag in his jacket pocket. Inside the bag was something dark brown like a clod of dirt.

"That's all there is to it." Zhang Yuan stood up and raised the bag in his hand.

Zhao Xuan stared at the bag in Zhang Yuan's hand, looking at the soil inside, and there was always a sense of familiarity.

But Zhao Xuan really didn't know where this familiarity came from, and he didn't know how to describe it, so he had to press his heart and didn't tell anyone else.

Song Shaofeng took the bag from Zhang Yuan's hand and didn't open it, just put it in the pocket of his body armor.

"Let's look around." Song Shaofeng also squatted down and took a closer look at the body, but he really didn't find any other clues, so he had to stand up and arrange.

"I lost it, don't let me see anything I find." After hearing this, Zhang Yuan quickly took the opportunity to take off his gloves and threw them aside.

Zhao Xuan rummaged through the grass around the corpse and found a box of bullets. The box was broken, and bullets were scattered around.

Lin Ling picked up the box, observed it, and found that the label was still there, pointing to the label and saying: "10 years of production in country R, 762 caliber." ”

"At least this savage is a product of the new century." Song Shaofeng laughed at himself.

When Zhao Xuan heard the caliber of the bullet and the geographical location, he first thought of the last attack, and subconsciously asked, "Could it be the person who attacked last time?" ”

When Song Shaofeng heard this hypothesis, his eyes lit up, and he praised: "Good idea, I think it's possible." ”

"Mean, the last time we were beaten up in the street by a group of lonely old people?" Zhang Yuan pointed to the corpse on the ground.

"Maybe it's something else that has made them old?" Zhao Xuan followed this train of thought and continued to stroke: "Judging from your teeth, isn't it quite young?" ”

"It's all speculation, and we'll have to find something to confirm it." Song Shaofeng looked around, turned his head and asked Lin Ling, "Which direction do the previous traces point to?" ”

"Guns." Lin Ling answered the question.

"What gun?"

"If you can find a firearm, you can prove that the previous speculation is not correct." After Lin Ling finished explaining, he continued to point to the northwest and said, "The earlier traces are facing that side. ”

"Let's go, search for a while and rest." Song Shaofeng picked up a small handful of bullets, stuffed them in his pocket, and commanded.

There's no rest in this place.

Further on, there are many traces that can be seen intermittently along the way, but it is not certain whether it is caused by humans or other large animals.

After resting for more than an hour halfway and having lunch, although the previous scene was not so good, Zhao Xuan still forced himself to eat more.

After all, they're searching, not hiking, and it's important to keep your energy up. In order to track down the source of the roar, they didn't stop for a moment.

After walking for more than an hour, Zhao Xuan and the others followed the traces and walked in front of a huge cave.

"Zhao Xuan, give me the phone." Lin Ling stood in front of the cave, frowned and thought about it, and suddenly spoke up.

Zhao Xuan hurriedly unlocked the phone and handed it to Lin Ling.

Lin Ling opened the map on Zhao Xuan's mobile phone and put it on the stone next to him, then took out his mobile phone, also called up a map from it, and put the two mobile phones side by side for careful comparison.

"This is it." Lin Ling handed the phone back to Zhao Xuan, pointed to the cave in front of him and said, "The location given by Ferdinand." ”

"In other words, what Ferdinand is trying to tell us is these 'wild men'?" Zhao Xuan was a little surprised, he was a foreigner, why was he so familiar with the territory.

Originally, today's plan was to check the news of Chen Degui, and he didn't plan to find the location given by Ferdinand, but who knows, two unrelated clues eventually point to the same place.

In any case, the cave needs to be explored.

Song Shaofeng looked at the time, it was almost three o'clock in the afternoon, and it would take at least two or three hours to walk back, and if they didn't want to get dark, they would have to turn back for another hour at most.

Song Shaofeng took off his backpack, took out a few small infrared cameras from his bag, and prepared to set up some monitoring devices around the cave, while saying, "Come back tomorrow......"

But before Song Shaofeng finished speaking, Zhao Xuan heard bursts of roars from the cave.

"There is another voice...... Zhao Xuan thought that it was the same as before, only he could hear it, and just opened his mouth, but he paused, because he found that everyone was frowning and looking into the cave.

The roar was still heard in bursts, and after the sound was amplified by the cave, it gathered at the mouth of the cave, and it sounded exceptionally clear.

"That's what you heard before?" Zhang Yuan turned his head and asked Zhao Xuan.

Zhao Xuan didn't speak, just nodded.

Song Shaofeng pondered for a while, leaned over again to put away the equipment on the ground again, gritted his teeth and said, "Come in!" ”

Having such a guide is much more efficient than searching for it without a clue. No one is sure if they will be able to hear it tomorrow, so Song Shaofeng naturally refuses to let it go.

"Use my and Zhao Xuan's flashlights first. The weapon is loaded, I will go in front, and Lin Ling will be behind. Song Shaofeng arranged the formation, and when he saw that several people were ready, he nodded and took the lead into the cave.

The entrance of the cave is only more than one person high, two or three meters wide, but the hole is a gourd-shaped, just a few steps forward, and then suddenly expanded. However, due to the small size of the hole, the light inside immediately dimmed.

Zhao Xuan walked beside Zhang Yuan, holding the gun in his right hand and holding a flashlight in his left backhand, and began to shoot in all directions.

The cave is deep, but at the moment it appears to be only one path, and the surrounding stone walls gradually narrow, stretching into the distance.

"There are traces." Song Shaofeng walked forward for dozens of meters and found a pile of charcoal fire on a small piece of flat ground on the edge of the stone wall.

Everyone is not familiar with determining the time of the campfire, but depending on the temperature, it will certainly not be a day or two.

"Let's go." Song Shaofeng got up and continued to walk forward.

I couldn't find any extra clues, so I had to keep moving forward, and before the roaring stopped, I could see if I could find the right route.

Moving on, there are more and more traces of human activity, including discarded empty cans, cigarette butts, and even specially cleaned up pits for excretion.

"This is the way of life of normal people, huh?" Zhang Yuan observed in the direction of Zhao Xuan's flashlight, and couldn't help but wonder: "It's not like a wild man." ”

But further inside, things became more and more cluttered, and durable items such as lunch boxes and water bottles, as well as first-aid supplies such as bandages and needles, began to be discarded around.

Continuing to walk inside, in the corner, Song Shaofeng found an artificially piled stone mill.

Several people walked closer and looked carefully, but found that the stone was picked up again.

A corpse, with the upper half of its body exposed, lying in a stone mound.

"Zhao Xuan, you go with Zhang Yuan to have a look." Song Shaofeng made a sound, then turned his head, scanned the surroundings with a flashlight, and guarded with Lin Ling.
