"Then hurry up." Xiao Meng began to look for a route down, and soon the two climbing ropes were arranged. The four men each stretched the rope to the bottom of the valley.

Mu Feng's physical strength seemed to have reached the limit at this time, as soon as he got off the climbing rope, he sat on the ground and gasped for breath, and began to cough from time to time, "No, I'm tired!" ”

Chu Tianyi walked over, "Brother Feng, can you hold up your body?" ”

"It's okay, it's okay," Mu Feng waved his hand, "I haven't been exercising lately. ”

Xiao Meng smiled, "Brother Feng, I see that you are not lacking in exercise, but overexercising, you will go to the bathing center a few times a month in the future, and this physical strength will come up." As he spoke, he gave Mu Feng a bottle of water.

"I'm also here to save a young woman who has lost her footing!" Mu Feng gulped down a few sips of water. "Xiao Meng, I see that you are quite energetic in, you go around and see if there is a flat place, suitable for lighting a fire and resting."

"Okay," Xiao Meng agreed, and walked to the side.

"I'll go with you." Chu Tianyi felt that he had just dragged his feet, and at this time he wanted to do what he could.

Chu Tianyi and Xiao Meng walked through the strange rocks, the bottom of the canyon was actually much wider than when they were seen from above, in order to improve efficiency, Xiao Meng and Chu Tianyi decided to look for it separately.

It didn't take long for Chu Tianyi to find a position near the edge, two huge stone pillars stood side by side, I don't know why one of them broke in the middle and fell on top of the other, so he inadvertently built a rock shed, and the space inside was not small, relatively dry.

Chu Tianyi beckoned the others to come over. Mu Feng looked at the situation here and nodded, "Yes, natural big tent!" So saying, he sat down on the ground against a stone, "I'll go, I'm tired!" ”

I don't know if it's because of physical strength or physical discomfort, Mu Feng's face at this time looked a little pale.

Chu Tianyi put down his backpack, "Then you can rest for a while, and I'll make a fire." ”

"No," Mu Feng pointed to the beard, "He is still here to make the fire, your bearded brother is professional in making fire!" ”

The bearded man saw that Chu Tianyi didn't quite understand, so he smiled and said, "I used to burn boilers. ”

"Brother Huzi, weren't you from the forest farm in the mountains before?" Chu Tianyi remembered that Mu Feng had told him.

"Yes, that's right," said the bearded man, as he prepared to make a fire, "When I was young, I spent five years in the forest farm, and at that time, in addition to working in the forest farm, I also went into the old forest with people to sell mountain goods, such as matsutake mushrooms, hazel mushrooms, pine nuts, and so on. Later, when the forest farm was disbanded, I went to the city to work, and at that time I worked as a boiler worker. ”

Chu Tianyi nodded, wanting to help the bearded man but couldn't intervene.

At this time, Mu Feng said to Chu Tianyi, "Tianyi, please go and call Xiao Meng back, your brother Feng's physical strength is really not good, how tired you are!" ”

"It's okay," Chu Tianyi happily agreed, and walked out.

As soon as he walked out a few steps, Chu Tianyi saw Xiao Meng walking out of the canyon, and he beckoned. Xiao Meng walked over when he saw him, "It seems that you have found a suitable place." ”

"What's going on inside?" Chu Tianyi pointed to the front and asked.

"It's nothing, it's similar to here, but," as he spoke, Xiao Meng took his hand up, and Chu Tianyi noticed that he had a square stone in his hand, "I found this inside." ”

"What is this?" Chu Tianyi asked strangely.

Xiao Meng groaned, "This thing is a little weird. As he spoke, he handed over the square stone.

Chu Tianyi took a look and saw that the stone was not naturally formed, but made of cement. On each side of the stone are carved numbers and some remnants of white lacquer. Not only that, Chu Tianyi also found that there was a crack on it, and there was a round hole in the middle of the crack, as if something had been drilled out.

Chu Tianyi looked at Xiao Meng in surprise, and Xiao Meng hesitated and opened his mouth to say something, but at this time, Mu Feng shouted beside him, "Hey, you two come over and rest for a while, and share the food!" Xiao Meng closed his mouth, didn't say anything more, turned around and walked towards the resting ground

By this time, the bearded man had already raised the fire. The four of them sat on the floor, their coats and shoes off, and baked them beside the fire. Suddenly, the air was filled with the smell of dampness and the smell of sweat in shoes, but at this moment, I didn't care about it.

Mu Feng threw some food and drink to Chu Tianyi and Xiao Meng, "We have a limited amount of food, so we have to ration it, so everyone be patient." As he spoke, he saw the stone in Chu Tianyi's hand, "Tianyi, what are you holding?" ”

Chu Tianyi handed the stone back to Xiao Meng, "This is what Xiao Meng found just now, and there are some numbers on it." ”

"Yes," Xiao Meng took the cement block, "I was just going to explore the front and accidentally found this on a flat ground, and there is a mark on it. I think it's a little weird. I'll bring it back to you. Since everyone had food in their hands, he took the cement blocks himself and showed them to everyone.

Mu Feng looked at it for a while and said, "This number should be a mark, or a landmark, I guess nine times out of ten it was left by the scientific expedition team back then." It corresponds to the data and materials on the scientific research record, so that the next time you come, you can quickly find the corresponding information. There's nothing strange about that. ”

Chu Tianyi chewed bread and said, "So there is no problem with our route, and now we are taking the route of the scientific expedition team back then." ”

The bearded man smiled, "There is only one road in this Grand Canyon, and it is difficult for you to go wrong!" ”

Chu Tianyi turned his head to Xiao Meng and said, "You are quite careful, there are stones all over the mountain, and you can actually find this landmark." ”

Xiao Meng's expression was a little strange, "Actually, the point of this stone is not the number on it, didn't you notice the small hole on it?" ”

Chu Tianyi nodded, "I found it, what's so special about that little hole?" Maybe it was accidentally chiseled back then. ”

"No, it's not," Xiao Meng shook his head and reached for his pocket.

The bearded man listened a little impatiently, "How do you kid TM talk and always spit out, if you have a fart!" ”

Xiao Meng fumbled in his pocket and said, "Actually, I'm afraid that you will say that I am making a fuss, but I think this matter is really strange. As he spoke, he took a small object from his pocket and placed it in the palm of his hand.

The thing was conical in shape, about three or four centimeters long, and had a smooth surface.

Xiao Meng continued, "Actually, I noticed that this stone was not because of the number written on it, but because of this, when I found them, this thing was nailed into the small hole in that stone. ”

As soon as Xiao Meng said this, Chu Tianyi, Mu Feng and the others suddenly showed surprised expressions.

The bearded man threw down the food in his hand, reached out and took the cone-shaped thing, and put it in front of his eyes to look at it carefully. He looked at it seriously for a long time, and suddenly there was a "tsk", and then his face changed, "This thing seems to be a tooth!" ”

Mu Feng also took it and looked at it, and then nodded, "Well, it does look like the tooth of some kind of beast, and there is a blood groove at the tip of this tooth, but it should be a broken tooth, broken in this stone." ”

"But what kind of animal tooth is this?" The bearded man shook his head and looked down in thought.

"Could it be a Siberian tiger?" Chu Tianyi opened his mouth and asked, he didn't know much about this mountain, and when it came to the beasts of Changbai Mountain, all he could think of was the Siberian tiger.

"No," the bearded man shook his head, "the average tiger tooth is much bigger than that, and even if it is broken, it won't be this size." ”

"Where's the wolf's fang?" Xiao Meng asked.

"No," the bearded man waved his hand, "I've been in the mountains and forests all these years, and I've never seen such a beast's teeth. Could it be that there are beasts in this canyon that we haven't seen before? ”

Chu Tianyi said in disbelief: "If this beast tooth is nailed to this landmark, then how much bite force does this guy need!" ”

"Siberian tigers don't have this ability!" The bearded man said with a stern expression.

"And what is this down?" Xiao Meng asked a little nervously. The bearded man, who had been in the mountains for five years, also shook his head silently.

Mu Feng took the tooth and gestured at the small hole in the stone, then looked up at Xiao Meng and said, "When you found this landmark, was it standing on the ground or had it already fallen to the side?" ”

"Fall aside," said Meng affirmatively, "this tooth is standing on it like a little mushroom, so I will notice." ”

"Let's go," Mu Feng stuffed the rest of the bread into his mouth, "take me over and have a look." ”

Xiao Meng led a few people to the location where he had just discovered the landmark of the scientific expedition, and he pointed to a place near the cliff and said, "Right here, I found it here." ”

Mu Feng looked left and right, "When you found it, that tooth was still stuck in the landmark?" ”

"Yes," Xiao Meng nodded, "I didn't know what it was, so I wanted to pull it out and take a look, you don't know, it took a lot of effort to pull this tooth out." ”

Mu Feng didn't speak, but searched around again. Chu Tianyi asked strangely, "Brother Feng, what are you looking for?" ”

"Where the landmark was supposed to be." Mu Feng replied without raising his head.

The four of them split up to look for it. Soon, Chu Tianyi found a depression more than ten meters away from the location where the landmark was found, he squatted down to check, and there were some cement fragments of the same texture as the landmark around the depression, obviously this should be the original location of the landmark.

He got up and shouted to the others, "Hey, I found it, here!" ”

Mu Feng walked over quickly, looked up left and right. The valley floor is flanked by rocky cliffs, and the top of the canyon is a dense jungle. He crouched down again, took out his short knife and dug into the hollow, and suddenly a green thing was revealed.
