Yin trace

From Ye Ya's intentional or unintentional words, Chen Ziyun got a great hint, that is, taking the scroll in Ye Ya's hand, he could learn many problems that Chen Ziyun was very interested in, or had great doubts about, and needed to solve.

Chen Ziyun believes that Ye Ya's actions are all to make him unable to bear the temptation, so that he can take out his notes and exchange them with her, so as to achieve her ulterior motives.

Although there is no way to prove what Ye Ya said, Chen Ziyun believes that the legendary Huanbu is made of ice silkworm silk.He is clear about the chill emanating from the ice silkworms, maybe the ice silkworms really have this miraculous effect of not being afraid of fire.

After resting for a while, everyone regained some vitality.Only lost three teammates, the atmosphere of the team was a bit gloomy.No one spoke loudly.

Shensha removed the metal arm and replaced the drive power supply.Seeing that it was getting dark at this time, he discussed with Ye Ya whether to camp here today.

Ye Ya directly denies Shensha's idea.She thinks this place is too open, and there is snow everywhere, making it difficult to camp, so she walks along the front for a while to find a better camp.

After pondering for a moment, Shen Sha also agreed with Ye Ya's statement.He is also very familiar with the plateau and knows that this is not a good place to camp.

Because Ye Ya was the first to run away when she encountered danger, the team members saw her expression was not very good.But she doesn't care about that either.Anyway, she brought three loyal subordinates with her, and she couldn't trouble the members of the 042 organization if anything happened.

Under Shen Sha's order, the team soon set off again.

The more he walked in, the more surprised Chen Ziyun felt.At least fifty kilometers have been traveled in the valley, but the end of the valley is far from being reached.Looking up towards the front of the valley, you can also see the mountains on both sides, as if there is no end.Chen Ziyun didn't even know what was waiting at the end of the road.

……

Less than an hour after the team advanced, a team member suddenly shouted: "What is that!" The voice was quite excited.Hearing the sound, it was from Liu Canghai, a geological expert in the team.

The team stopped suddenly and looked at Liu Canghai's position.At this time, Liu Canghai was holding a telescope in his hand and looking forward, apparently he had discovered something.

"What's wrong?" Xie Feng said in a bad tone.

Chen Ziyun frowned slightly, picked up the binoculars and looked, and his calm face instantly turned into an unbelievable look. "What's the matter?" Wang Xiaowu next to him asked puzzled.Judging from Chen Ziyun's expression, what he saw shouldn't be anything scary.

"On the mountain wall ahead...you can see for yourself..." Chen Ziyun's voice became very strange, and he handed the telescope to Wang Xiaowu.

Ye Ya squinted her eyes.She didn't need a telescope, she just raised her head slightly and looked at a mountain wall about two miles away, blocking the way, and she already knew what it was.

"Is that where we are going?" Shen Sha asked Ye Ya in a low voice.There was some confusion in Shen Sha's voice.Because the record left by Xu Xiake is obviously different from the discovery in front of him.

Ye Ya shook her head calmly and said, "No, not here."

"Then what is this?" Shen Sha asked his own question.

"I want to know too." Ye Ya replied calmly, "Go and see first."

The mountain wall in front of everyone is actually one side of a mountain, which divides the valley into two.The valley continued meandering in two directions, still without end.And no one cares about the direction of the valley.Everyone looked at the mountain wall in front of them in horror, shocked and speechless.

The main body of the mountain wall is granite, nearly a thousand meters high, and the mountain is so steep that it is almost vertical and extremely smooth.Standing in front of the mountain, everyone felt a small feeling in their hearts.However, this small feeling of self is far less shocking than the present.Because on this vertical and smooth mountain wall, many caves were dug out by someone.

The caves are densely packed, all over the mountain wall, probably no less than a thousand.The entrance of the cave is about two meters long. Looking up from the bottom, it is impossible to tell how deep it is inside.Looking from the bottom up, I found that the cave closest to the ground is also about [-] meters high!

"Hey, who dug these caves?" Liu Canghai swallowed, and looked at Chen Ziyun with begging eyes.He is a geologist, and he knows how difficult it is to dig a cave out of granite. These more than 1000 caves are even more unimaginable!That's on top of a cliff!Moreover, this is a snow mountain plateau, with the current level of technology, it is difficult to complete such a huge project!

Chen Ziyun also had a dazed look on his face.From the moment these caves were discovered, the question had been on his mind long enough!

Countless ethnic groups that once existed on the plateau flashed in Chen Ziyun's mind.But Chen Ziyun knew that no matter which ethnic group it was, it would not be able to complete such a difficult project!

"Us, let's go up and have a look?" Chen Ziyun didn't answer Liu Canghai's words, looking at Chen Sha, his voice trembled slightly.As an archaeologist, the cave in the mountain wall in front of him is the deadliest temptation for him.

Not only Chen Ziyun, but also Wang Xiaowu, who saw this scene, also recovered from his sickness, and took many photos of this mountain wall from far to near.There was also a trace of blush on her pale little face, and her eyes were as red as a rabbit. If anyone refused to let her go up to see what secrets were hidden in these caves, she might find someone desperate at any time.

Chen Sha glanced at Ye Ya.

Ye Ya thought for a while, then nodded solemnly: "Okay, but be careful. We don't know who opened these caves and what dangers will be inside, so we must be careful." Ye Ya twitched suddenly when he said this Nose, said: "There is no smell of Jade Rakshasa here, and a danger can be eliminated."

There are no roads carved out of the mountain wall for people to walk on.But this is not a problem for the players who have long been used to climbing mountains and mountains.Under the command of Shen Sha, several team members took out their equipment, dug nails on the mountain wall, and installed climbing ropes.

The rest of the people were not idle either.It was getting late at this time, and the team spent the night below the mountain wall.

The dusk was getting thicker, and when I looked up at the dark cave on the stone wall from below, I suddenly felt palpitations.For some reason, he suddenly felt that these holes, like countless monsters, were opening their mouths wide open, waiting for their prey to come.

"Ziyun, which civilization do you think left these caves behind?" Liu Canghai asked again as he wolfed down a can of heated meat.Although the main directions of the two are different, they are both scholars in the team, so they naturally have more topics to talk about.
