"Hey, what is this?" Chu Tianyi asked in surprise.

Mu Feng picked out the thing with a short knife and spread it on the ground to look at it, "This is a food packaging bag." The packaging bag has been torn to pieces and incomplete, but the word "meat" on the food name can still be identified.

"How could this happen?" Xiao Meng asked, "Someone arrived before us? Will the family members be there?"

"No," the bearded man shook his head, "You see what the packaging bags are like, so you have been buried for more than seven or eight years."

"I'm afraid it's twenty years," Mu Feng said, "This packaging bag was originally buried under the landmark. It should have been when the scientific expedition team dug a hole to bury the landmark, some team members threw the leftover food inadvertently or intentionally."

When Chu Tianyi heard Mu Feng say this, he looked at the landmark and the beast tooth in Xiao Meng's hand, and suddenly moved his heart, "Brother Feng, do you mean that the beast is for this?"

"Yes," Mu Feng looked at Chu Tianyi and smiled, "Tianyi is the same as I thought. The reason why that beast wanted to pull out the landmark was attracted by the smell of food buried beneath it."

"Then this guy is fierce enough," the bearded man touched the hole in the landmark. "In my experience, this thing has one or two pairs of prominent fangs, so it must be a beast in this way!"

Mu Feng stood up and looked around vigilantly, "Everyone be alert, this canyon may not be as simple as we thought."

As soon as he said this, the others' hearts changed. The scenery here is so beautiful, Chu Tianyi's originally relaxed mood has become a little heavy at this time, and even the strange rocks seem a little hideous.

Seeing that no one was talking, Mu Feng looked up at the other three, "What? Are you scared?"

"How is that possible!" The bearded man smiled indifferently, "There is no reason to be scared away by an unknown animal tooth. Besides, the Qi family and I have a account that has not been settled!" Xiao Meng also nodded archly from the side.

Chu Tianyi looked at the green packaging bag, "Even if an unknown beast was attracted to this place at that time, so many years have passed. Maybe it has been no longer here, or it has died."

"I hope so," Mu Feng smiled, "Let's go, let's continue to set off."

As we move forward, the cliffs on both sides of the valley become steeper. Those walking in the middle will feel an inexplicable sense of oppression, as if the stone walls on both sides will suddenly squeeze down.

The Changbai Mountain Grand Canyon is the largest volcanic rock landform in China, and the terrain in the valley is extremely diverse. It is very difficult for Chu Tianyi and the other four to walk. Sometimes they have to cross stone pillars that soar into the sky, and sometimes they have to cross gullies several meters deep.

With the exhaustion of physical strength, everyone no longer had the interest of coming in. Everyone was not talking, but just bowed their heads to rush. Chu Tianyi felt that his underwear was soaked with sweat. Although he was very tired, no one said he would rest. Especially Mu Feng, he was so tired that he was out of breath, but he still gritted his teeth and persevered. Therefore, Chu Tianyi was not good at speaking first.

After walking like this for more than two hours, they discovered two more landmarks during this period. The numbers should be the continuation of the landmark that Xiao Meng discovered before. Chu Tianyi looked at the number above and said, "It seems that our speed is much faster than the scientific expedition team that year."

"That's natural," Mu Feng took a few breaths before he took off and said the following words, "The scientific expedition team was a large group of people and various equipment, and their purpose was to investigate and study from time to time. Therefore, we are not only faster than them, but several times faster."

Chu Tianyi looked at Mu Feng's face and turned pale, "Brother Feng, don't take a break, you can slow down and let's go."

Mu Feng was energetic and waved his hand, "Don't, I don't want to be the one who drags my back, I can still hold on! Let's go!" After saying that, in order to prove that he is okay, he tried hard to smile, but he looked miserable.

After walking for about half an hour, the sound of running water was faintly heard in front of him, and a faint water vapor floated in the air.

Several people walked around a stone pillar, and a river appeared in front of them. The river surface was not wide, about two or three meters, but the water flowed very quickly. What's strange is that the river did not flow along the canyon, but turned a corner and flowed into the mountain.

When everyone walked up to him, they found that there was a cave more than two meters wide at the bottom of the cliff on one side, and the river flowed into the cave. The upper part of the cave entrance was relatively flat, like a naturally formed "stone bridge".

The bearded man raised his flashlight and shone it into the cave from one side. The cave was dark and deep, and I don’t know where it leads. The turbulent river water poured into the cave and made a strange sound, like someone was crying, or like some animal roaring in a low voice. In short, this sound made people feel a little chilled on their backs.

Due to the heavy humidity here, the surface of the "stone bridge" above the cave has thick moss, which is like a layer of turf. The stone surface is not very wide, so the four people can only pass through it in turn.

"It's wet and slippery, please be careful!" Mu Feng said, and then walked up first.

Xiao Meng walked behind Chu Tianyi and looked at the river water below, "You have to step on it firmly. If you make a mistake, you will go directly into the cave." After saying that, he suddenly laughed, "You said, if you fall in, the body will float out of which river."

Chu Tianyi was about to turn his head and tell him not to be a crow's mouth, but before he could speak, Xiao Meng said "Oh" and fell into the river as soon as his feet slipped. Chu Tianyi quickly looked at Xiao Meng's arm and pulled him up hard.

But unexpectedly, Xiao Meng, who was not fat, made Chu Tianyi very difficult to pull it up. He felt that there was a kind of force pulling Xiao Meng down.

Chu Tianyi tried his best, but he still couldn't hold on. At this time, the bearded man walking behind also rushed up, and the two of them grabbed Xiao Meng together. Chu Tianyi grabbed Xiao Meng with one hand and grabbed the rock next to him with the other hand. However, there was a layer of water vapor on the stone, which was very slippery and could not borrow any force.

"Ah! Ah!!" Xiao Meng suddenly screamed in fear, "I have something on my feet!! There is something!"

At this time, Mu Feng rushed back. He lay on the ground and leaned over to grab Xiao Meng's pants, then shouted at Chu Tianyi and the bearded man, "I'll count one, two, three, and the three of them will pull hard together! One, two, three!!"

As soon as Mu Feng's word "three" was released, Chu Tianyi suddenly used all his strength to lift it up, and the bearded man gritted his teeth and his face turned red. The three of them worked together, and Xiao Meng was pulled up a lot. Mu Feng held Xiao Meng's legs. Chu Tianyi suddenly saw a strange thing wrapped around Xiao Meng's ankle, which seemed to be an octopus' tentacle, and the other end of the tentacle extended into the cave.

Chu Tianyi understood that Xiao Meng just shouted that the thing on his feet should be referring to.

"Hold it!!" Mu Feng shouted. At the same time, he grabbed the short knife at his waist and held it in his hand. A silver light flashed, and the blade slashed hard on the "tenta" wrapped around the little maiden ankle.

What they didn't expect was that this tentacle was very tough, and the sharp blade did not cut it off, but only left a shallow wound.

But despite this, the knife still worked. The "tenta" shivered for a moment, immediately let go of Xiao Meng's ankle, and indented it "swishly" into the hole.

Chu Tianyi felt his hand relaxed, and Xiao Meng was pulled up by the three of them.

Xiao Meng's face was pale at this time and his lips were trembling.

"Go away!" Mu Feng whispered, "Get out of here!"

Chu Tianyi and the bearded man pulled Xiao Meng up, and the four of them quickly jumped over the cave and arrived on the opposite river beach.

Xiao Meng was scared this time. As soon as Chu Tianyi and the bearded man let go, he collapsed on the ground, gasping for breath without saying a word.

Chu Tianyi patted his shoulder and handed him the water. Xiao Meng took it and took a few mouthfuls into his mouth. Then he calmed down a little, "It's so scary that I'm so scared. I thought I was about to finish playing!"

Chu Tianyi looked at the cave with lingering fear, "What was that thing just now?"

"I don't know," the bearded man shook his head, "I haven't encountered this before."

Mu Feng's face was not very good either. He had already consumed most of his physical strength, and he tried his best to save Xiao Meng. At this time, Mu Feng was a little overdrawn and sat down against a huge rock and took a few deep breaths.

The bearded man walked to Mu Feng, "Brother Feng, this place is a bit weird. There are strange things one after another. Will there be anything unclean?"

Mu Feng looked at him squintedly, "Don't talk nonsense here, what unclean things? I tell you, there are no monsters and ghosts in this world, only things we don't understand."

The bearded man still had some difficulty accepting, "But, that..."

Before he finished speaking, Mu Feng waved his hand to interrupt him, and then looked at Chu Tianyi and Xiao Meng, "Think about it, think about it, Changbai Mountain has existed for at least millions of years, it has to be many times longer than the history of human beings. In addition, the hundreds of years of closure in the Qing Dynasty. Changbai Mountain can be said to have retained an extremely complete ecosystem, including various rare plants and animals. The Grand Canyon has only been discovered for more than 20 years. So, in this paradise of animals and plants, because there is no external disturbance, it is very likely that it has retained a wealth of species, among which there are species that we do not know yet."

After hearing Mu Feng's words, Chu Tianyi couldn't help but nodded, "Well, it makes sense."

"So," Mu Feng continued, "If you don't understand and don't have enough knowledge, just use your brain more often. Don't pull on unclean things at any time and scare yourself!"
