There are several common types of red sandstone, one of which is no different from ordinary sandstone, and is mostly used for paving and building materials.

Completely weathered red sandstone, very old.

But where does the red sandstone come from in the mountains above two thousand meters above sea level?

Professor Zhao became excited, dug out the red sandstone, and carefully wrapped it. The red sandstone of the ancient road pavement is more than 20 centimeters thick, and the road is more than two meters wide, and it is not known how long, but in any case, this is an unimaginably huge project with great archaeological value.

"How long is the Demon Eye Lake?" Zhao Jiyang asked when he was really tired from walking.

"More than an hour. Ye Chen said.

"I just said more than an hour, and now it's still more than an hour, I'm tired of walking, carry me. Zhao Jiyang puffed out his cheeks, took Ye Chen's backpack, and was not afraid of other people's laughter, and leaned on Ye Chen's back: "Do you still carry it?"

"I can carry it. Ye Chen said with a smile.

Zhao Jiyang shyly leaned on Ye Chen's back.

The next journey is easy to walk, Ye Chen doesn't want to delay time, and takes a big step to lead the way in front.

Zhao Jiyang yawned: "This road is older than climbing Mount Emei." ”

"Have you walked the hiking trail of Mount Emei?"

"Walk through, set off in the morning, climb to the passenger station below the golden dome in the evening. It feels like the road here is more tiring. ”

Ye Chen smiled.

There is no road on this side of Mengshan, and I feel more tired when I keep wading here. Moreover, the peak of Mengshan Mountain is much higher than that of Mount Emei, of course, it is still far to the peak, and it is necessary to cross the Demon Eye Lake.

On the way here, a large group of people walked very slowly, and they had been delayed too much, Ye Chen was still in a hurry to go back in the evening to sell tea, unconsciously speeding up the pace, leaving a group of people far behind.

"Walk slowly, aren't you tired?" Zhao Jiyang patted Ye Chen on the shoulder and asked.

"Not tired. ”

At this point, Uncle Mu already knew where to go to Demon Eye Lake.

Ye Chen walked in front without waiting for everyone, telling the story of his childhood and his master in the mountains all the way.

At the end of the ancient road of about 2,000 meters, I climbed over a small hill and walked through a large valley, and my vision suddenly widened, and all I saw were independent mountains, as if I had traveled to another world.

This is a very iconic karst landform, one by one big mountains, the terrain between the mountains is flat, and the Demon Eye Lake is here.

The red sandstone of the ancient road should have been mined here, a long time ago, the ancient road may have been connected to the side of the Demon Eye Lake, but it was very old, and the ancient road sank or was covered with vegetation.

Ye Chen let go of Zhao Jiyang and took him to climb halfway up a hill by the lake. Looking down from above, a round lake, like the bloody eyes of a monster, is particularly infiltrating. The lake is not big, almost the same as two Qingshuigou reservoirs.

The location of the Demon Eye Lake is like a cave in the mountains, surrounded by very high mountains, except for the place where it comes, it is particularly steep. It is about twice the size of Qingshui Village, with twenty or thirty independent hills, like chess pieces on a chessboard. The five surnames of Qingshan Town live far away to the west of Ranshi Mountain and south of Demon Eye Lake, and they have guarded this place for at least one hundred and fifty years.

"It's really like the eyes of a monster, if you go to the lake weeds, it looks even more infiltrating and creepy. Zhao Jiyang shuddered.

Ye Chen also felt that this was special, in addition to infiltrating people, the air temperature was dry and cold, and now Ye Chen had other feelings. Some of them are similar to being in a cave space, giving people a strange unreality.

Ye Chen rubbed the stubble on his chin, hugged Zhao Jiyang in his arms, and suddenly felt that he was being stared at by something......

Ye Chen believed in his self-consciousness and looked around. This sudden appearance of a sixth sense alerted him.

After looking around for a long time and finding nothing, there was a human voice from the bottom of the mountain, and on the tree not far from Ye Chen, a big bird suddenly fluttered its wings and flew out.

Ye Chen was startled, could it be that the feeling just now was that he was being hit by this big bird?

The blackbird was larger than a crow and slightly smaller than a domestic chicken.

As the voices approached, Ye Chen took a few photos of the Demon Eye Lake and went down the mountain: "The front is the Demon Eye Lake." This is the red sandstone geology, forming an eye-like lake. I took a picture and took a look. Ye Chen took out his mobile phone and showed it to a few people.

"How can red sandstone be here?"

"It's weird. ”

"Could it be that there was a period of violent geological movement......

The scholars discussed, but couldn't say why.

Then the evaluator of the scenic spot has to take pictures everywhere, and the others come to the lake: "It's really a red lake." ”

"It's the red sandstone at the bottom of the lake. The water is very clear. "This lake also has ditches that eventually flow into the ground, and the water is crystal clear. There are fish in the lake, a fish that resembles the shape of a fish, with a smaller body, finer scales, blue-black, and a reddish belly. Ye Chen doesn't come to this place often, he has only seen about ten centimeters, he grabbed it and boiled it directly, without putting other ingredients, and it was very fresh and tender in his memory.

The memory of the age of ten is not very clear.

Ye Chen looked at the time, it was almost three o'clock in the afternoon, urging everyone to hurry up and finish the matter and go out of the mountain.

"Uncle, urge. According to the calculation of the time into the mountain, everyone walked for almost six hours, and now it is almost dark when I go out, and I am still in a hurry to go out to sell tea. ”

"What's the hurry? Can't stay overnight in the mountains......"

Ye Chen didn't say anything, Uncle Mu and the others quit, and said, "It's dangerous to spend the night in the mountains." Better go out ......."

"Don't alarm the mountain god. ”

Where the Demon Eye Lake is located, it is still relatively sacred in the minds of the five major clansmen.

I don't know if there are any ghosts and ghosts on Mount Kamiyama, but no one wants to spend the night here.

Urging to hurry up and take pictures, hurry down the mountain. With the strength of these people's feet, it will not take too little time to descend the mountain, at least more than four hours.

Actually, everyone walked fast enough on the way here. I'm tired now......

"Just come here and leave now, is there any mistake. Yang Huan was feeling the magic of wonderful nature, listening to Ye Chen's urging, he muttered very unhappily.

The two male classmates next to him looked at Ye Chen and then at Zhao Jiyang, and looked at each other.

"It's dark and it's hard to walk in the mountains. Ye Chen said speechlessly.

"Uncle Mu didn't say that there was a shortcut, and he walked into the road when he went back. Yang Huan and Ye Chen raised the bar, and Professor Zhao looked at Mu Fusheng, as if asking what he meant. If he could stay for two more hours, he would still like to look around, maybe there would be a big discovery.

Ye Chen didn't give face at all, and pointed to the opposite slope that was almost as steep as a cliff: "Take a shortcut, and ask if you can climb up." Uncle, I really have something to do later, and the time is almost gone. ”

These people really haven't walked the mountain road or whatever, and they are not afraid of death.

"Waiting. I went over and asked Professor Kang. Li Zhi looked at the time and knew that he had to go down the mountain.

Li Zhi walked away, and Professor Zhao came over and asked, "Xiao Ye, it's dangerous to spend the night in the mountains?"

"There are wild boars in the mountains. I don't know if it's dangerous or not, I don't have the experience of spending the night in the mountains. Ye Chen shook his head: "The night in the mountains is very cold. The altitude here should be around 2600 meters......"

"2561 meters. Professor Zhao took the instrument: "Before we knew it, we had climbed more than 1,000 meters. ”

"We've been going up all the way, and we're going pretty fast. "Ye Chen took him to the Demon Eye Lake a few times after he was a child, usually picking tea leaves in the Troubled Stone Mountain for two hours, and then going to the Demon Eye Lake to fetch water to boil tea, and then followed down the mountain. It was almost dark when we started at dawn and went down the mountain.

"Are you familiar with this area?"

"It's still familiar over there. Here in Demon Eye Lake, I haven't been here for more than ten years. ”

Uncle Mu came over and said, "I basically come once or twice a year. The professor needs a guide?"

"After preliminary judgment, this area has high archaeological value, and I am ready to apply for a large-scale archaeology. After about a month or two, you need a guide who is familiar with the conditions in the mountains. ”

Ye Chen's cheeks twitched slightly: "In winter, there is snow in the mountains. ”

Professor Zhao was stunned for a moment and laughed: "Then next year." However, the preliminary investigation and research work also needs a guide, and when I apply for approval from above, it should be like a week. ”
