"This is called the Four Elephant Tile, and the one engraved on it is not a turtle, this tile is broken, and it was originally carved with Xuanwu. Some of them are carved with green dragons, white tigers, and vermilion birds, so they are called four elephant tiles. Xuanwu, have you heard of it? Read? Bei Qin pointed to the tiles and said.

"I know," Gu Xiaoqian was a little impatient, "Xuanwu is also in the north." The turtle and the snake are the two insects of Xuanwu, so the snake is the residence of Xuanwu, and the star of danger is also. ”

This time it was Bei Qin's turn to be at a loss, and he looked at Gu Xiaoqian with question marks in his eyes.

Gu Xiaoqian looked at him proudly, "This is what "Zuo Chuan" said, have you heard of "Zuo Chuan"?" Read? Got it? ”

Bei Qin didn't expect to be slapped in the face so soon, turned his head speechlessly, and instructed the guy, "Where did you find it?" Take me over and see it. ”

The man took Pei Qin and Gu Xiaoqian through a small wooded area to the bottom of the hillside, where a meandering river flowed rapidly.

The man pointed there, "This is what I found at the bottom of the river." ”

Bei Qin walked to the river, squatted down and looked at it for a while, then suddenly smiled, and casually took out a stone from it, which had a semicircular dentation. He took it back to Gu Xiaoqian and showed it, "The indentation on this has a regular arc, it is obvious that it is chiseled by a tool similar to a gun, and there must be a large-scale project in the upper reaches of this river." ”

"Oh," Gu Xiaoqian stretched out her hand to take it, "So the ruins of Gu Xu Kingdom are in the upper reaches of this river?" You should be able to find the people of the Qi family and the Chu family there, right? ”

"If they are here for the ancient Xu Kingdom, then they will definitely be able to find them." Pei Qin casually threw the stone into the river again.

Gu Xiaoqian nodded, and couldn't help frowning slightly.

Bei Qin saw that her expression was wrong, so he asked, "What's wrong?" What to ponder? ”

"It's nothing," Gu Xiaoqian shook her head, "I just think I'm afraid things won't go so well." I have met Chu Tianyi of the Chu family, and he seems to have no idea about the secret box, and I don't know if it is pretended. And the Qi family also seems to be eyeing the secret box. If the secret box is really in their hands, it will be difficult to get it back. ”

"It's okay," Bei Qin waved his hand nonchalantly, "We are not afraid of coming to the martial arts, you come to the text, use the martial arts." ”

Gu Xiaoqian looked at Bei Qin and smiled, nodded slowly, and said softly, "Bei Qin, thank you." ”

Bei Qin was stunned for a moment, smiled and turned around, and suddenly shivered, "Oops, meaty!" ”

Gu Xiaoqian immediately flew up behind......

Bei Qin and a few of his fellows walked in front, swimming up the river, with a clear shoe print on their buttocks. Gu Xiaoqian followed behind angrily.

What they didn't expect was that the course of this tributary actually entered a cave. The water of the whole river actually flowed out of the mountains.

Bei Qin and a few right-hand men took out their flashlights and walked to the entrance of the cave to look inside, this black hole was very large, more than ten meters long and high.

A guy pointed to the inner wall of the cave and said, "Little Beiye, you see where the green moss grows here, it is almost fifty or sixty centimeters higher than the current water level. With so much drop in the water level, there must be a river channel exposed and should be accessible. Even if there are individual sections of the road that don't work, we still have a few or two inflatable rafts, and I guess they can handle it. ”

Bei Qin nodded when he heard this, and Gu Xiaoqian also came up and asked, "Should we enter from here?" ”

Bei Qin looked inside with a flashlight, and said: "The water system of the Changbai Mountains is developed, and the underground water system is also intricate, so it is a relatively safe way to enter from here. ”

"Isn't it dangerous to be dark here?" Gu Xiaoqian had never entered such a place, and she was very uneasy.

Bei Qin turned his head and glanced at her, "There are definitely no tigers and black bears in this, but poisonous snakes, rats, scorpions, and centipedes are definitely indispensable, so you'd better be mentally prepared." ”

"Huh?" Gu Xiaoqian's mouth grew when she heard it. She is not a timid person, and the tiger black bear may not really be much scary to her, but as a girl, the poisonous snake, mouse, scorpion, centipede, still makes her numb.

Bei Qin looked at her and reached out and took out a small bottle from her bag, opened the cap of the bottle and poured out the medicinal powder from it, and slapped it on Gu Xiaoqian's body, and suddenly a somewhat pungent smell wafted away, Gu Xiaoqian jumped away with a scream, "Dead Xiaobei, what did you throw on me?" ”

Pei Qin shook the vial in his hand, "This is the prescription that the fourth uncle taught me at the beginning, it is specially designed to prevent poisonous insects, snakes and ants, and it is effective in my own test, don't worry." As he spoke, he shoved the vial into her hand.

Gu Xiaoqian closed her mouth a little reluctantly, gently twitched her nose and sniffed her body, and immediately frowned, but at the same time she put the vial into her pocket helplessly.

Bei Qin tightened the backpack strap on his body, took out his flashlight, and waved his hand at the others, "Go, go into the hole!" ”

At this time, on the stone steps of the underground canyon, Chu Tianyi, Mu Feng and the others were still moving forward cautiously.

After the incident of finding the dried corpse before, everyone has some thoughts. No one spoke for a while, except for the shaking of a few flashlights in the darkness, only breathing and footsteps remained.

The bearded man still seemed to be a little mindful of being teased by Xiao Meng just now that he was afraid of the corpse, and he jumped past Chu Tianyi and walked behind Mu Feng. Chu Tianyi looked back at Xiao Meng, he didn't seem to care, and held up his flashlight to shine east and west.

Chu Tianyi turned his head, and his mind was still the dried corpse he had just found. He couldn't help but continue to wonder, who are these people? Why did you find this place too? Will the expedition team led by my father also find this place? If this is the case, will there be a conflict between the two sides? If something happened to my father's scientific expedition team, could it be related to these people?

These questions were repeated in his mind, but he could not come up with a definite answer.

Suddenly, Xiao Meng slapped him in the back. Chu Tianyi turned his head and asked, "What's wrong?" ”

Xiao Meng's face was a little nervous, "Brother Yi, why do I think there is something behind us?" ”

"Really?" Chu Tianyi raised the flashlight and shone it behind Xiao Meng, and there was nothing on the dark steps except the shaking of the flashlight. He looked at Xiao Meng and smiled, "Are you too nervous, there's nothing over there." ”

Xiao Meng scratched his head, "But I really heard it, and more than once." ”

"Maybe it's the wind or something," Chu Tianyi patted Xiao Meng, "Otherwise, you should go ahead of me." He pushed Xiao Meng to the front, and suddenly felt that this scene was so familiar, as if it had happened before. He recalls the first time he was hallucinated by a lyreworm, and he just hoped that nothing would happen this time.

Chu Tianyi walked at the end of the line, I don't know if he was affected by Xiao Meng, he also began to pay attention to the movement behind him from time to time. At first, the road was normal, but at a small bend, Chu Tianyi suddenly heard a rustling sound behind him, he couldn't help but be stunned, and realized in his heart that maybe what Xiao Meng said just now was true, and he didn't hear it wrong.

Chu Tianyi clenched the flashlight and turned his head suddenly, only to find that there was nothing behind him. He shook his head strangely, he and Xiao Meng both heard it, but they couldn't find anything that made a sound, could it be some special natural phenomenon?

He looked behind him for a moment, but still found nothing. He had no choice but to turn around and continue walking.

After walking for a while, Mu Feng at the front suddenly turned his head and said, "Everyone, this stone staircase is to the end." Sure enough, as Mu Feng said, soon they reached the end of the stone steps, and beyond that, there was a dark passage.

Mu Feng raised his flashlight and looked around, "How far are we from the ground now?" ”

The bearded man pondered for a moment, "I think it's about one hundred and fifty meters." ”

"So deep?" Xiao Meng shrunk his neck in some surprise, "Is this place sturdy?" It's not going to collapse after all these years, right? ”

"Shut up!" The bearded man glared at him, "Can you say something auspicious!" ”

Mu Feng smiled, "It's okay, don't worry, this place was built by opening the mountain, unless the mountain collapses, it is very strong here." ”

Xiao Meng didn't seem to be listening to Mu Feng, but held a flashlight to shine it a little farther away. Chu Tianyi asked him curiously, "Hey, what's wrong with you?" ”

Xiao Meng lowered his head slightly, squinted his eyes, pointed to the front and said, "Hey, look, is there something that moves?" ”
