The land of Muxi Ridge, the herd here refers to a mountain peak, there is a record in the Book of Mountains and Seas, the shepherd stands for three days, enters with the sun and the moon, the tail king, but says three hundred zhang, stands in the mountain wall, can observe the world's things.

Mushan is a giant god in ancient times, belonging to Pangu's first-class subordinates, it regards itself as extraordinary, and gradually no longer wants to succumb to the knees of others, so he began to go west, but his original mission has not been completed, so when he fled to the land of Xiling, he was cast by the great god and turned into a mountain, and Mu was still standing when he was punished, so what humans saw was a columnar mountain high in the sky.

However, as the years changed, this mountain began to sink into the ground at a visible speed until it sank to the position of the back, and then the mountain that people saw became a smooth wall again, so some people called this mountain Bishan.

In the meantime, I don't know whether hundreds of years or thousands of years passed, and the original Makiyama completely sank into the ground, but after the top of the original Makiyama collapsed, another spectacle appeared.

It is rumored that after someone saw Mushan enter the ground, a huge cave appeared on the ground, and tens of thousands of sand gushed out of the cave, and these sand went straight up to the sky as soon as it came out of the ground, covering the heaven and earth, the sun and the moon, so there will be a sentence that the sun cannot be seen above, and the yellow spring cannot be seen below.

Slowly dozens of days later, the sand pillar fell, covering the entire Xiling land, and then the Xiling land was no longer polished. Because the people nearby saw that there was no danger, they had the courage to tie a rope around their waists and jump directly into a huge cave full of sand, but the rope went down hundreds of thousands of zhang, and the person was still going down, and some of them were a little panicked and began to pull the rope in reverse, but after the rope was completely pulled out, there was no person at the end of the rope, and the rope was not broken, but the person untied it by himself.

For a while, no one dared to go down, until a stranger came, who carved a small boat out of a thick white wood abundant in Xiling, and fell into the sand cave in the eyes of the others.

It was nearly eighty days before he entered a space that was unbelievable, and for eighty days, he had been surrounded by sand, and in addition to sand, it was still sand. He had been diving for about six hundred miles, but when he saw the light again, he found that he was back on the ground, but strangely enough, he came out like an upside-down hat, and what he saw was the same as the earth. And under this scene, all of them are people similar to the Dayu clan.

But we don't know what exactly is meant by the earth and the sun reaching the sky. The rest of the content was interrupted by the fat man, so it seems that he doesn't want to say anything about looking at Manan's appearance.

Based on these things, it seems that this is a geological subsidence and a volcanic eruption caused by geological subsidence, and the sand may be either volcanic ash or yellow sand that fell into the crater after geological subsidence.

But Manan disagreed: "Later in the text there is also a white river that runs into the ground, and the river is overflowing, and there are thousands of evil spirits in it, and the man who made the boat down the white river followed the white river until he returned to the land, and when he returned to the ground, he was silent, as if he had become dumb." Do you know that river is that one? ”

I pointed to the sand river beside us like a rushing river, Manan nodded, and then the fat man said: "What Dayu people, in my opinion, that is the road to hell, people have said that they can't see the Yellow Spring." And the white river, with thousands of evil spirits in it, what do you think it is? That's the Lethe River. ”

I grinned at him, this guy's imagination was a little too outrageous, so he scolded: "Come on, if you want to say that this is the Lechuan River, then we have to drink a bowl of soup and cross a bridge if we go down again." ”

I ignored the fat man, called Manan, and continued to ask, "You don't say this to relieve us. ”

Manan turned his head back to me, the corners of his mouth turned up slightly, this movement caused the muscles of his face to twitch a little, he looked around, and then continued: "The direction of this river is to the west, but there is a very special place, these sands do not actively flow towards the west, but are attracted by something, they have the power, and their destination is the legendary abyss of six hundred miles of the boatmaker. And the place I'm going to is the entrance to the quicksand abyss. ”

"I would venture to ask, where are you going, what are you doing? Isn't there anything more valuable than gold? "Because my understanding of Manan is still in the stage of seeking wealth, I didn't think about it and asked directly.

Manan just turned around and smiled mysteriously at me, and then didn't say anything, and walked straight ahead of his pace.

I was a little confused, and the speed was a little slower, and the fat man glanced at me and whispered, "Eat it, you, I said don't deal with crazy people, you still don't believe it." ”

We had no choice but to continue marching, not only for the sake of the deal reached between the two sides, but also to find the exit as quickly as possible, otherwise we would have no supplies, no water and no food, and even the flashlight would have less than half of the power left, and I am afraid that in another four or five hours, we would have to move forward in the dark.

There is a paragraph in Tao Yuanming's Peach Blossom Spring, which is extremely narrow at the beginning, and only then can he understand people. After dozens of steps, it suddenly became clear. The land is flat, and the houses are like houses. Linked to the story that Manan said was recorded in the clay pot, it is indeed a bit similar, will the place he went to is not the ground, but another place, an outdoor peach orchard, it stands to reason that the age of the herd is later than the three emperors and five emperors, and he was turned into a huge peak, the mountain peak sinking This is a process that started at least a hundred years and a thousand years, and when the mountain sinks into the ground, it may have been the Shang and Zhou dynasties, according to the year of the clay pot, it is indeed the era of the end of the Shang and early Zhou dynasties, and at that time, such as the cave met the clansmen of Dayu, This story is indeed similar to the story of the Peach Blossom Spring in which the fishermen of the Eastern Jin Dynasty passed through the cave and met the people of the pre-Qin period, but both are similar to mythological stories.

And the biggest doubt is whether the master found by the Italians that Manan said is really a master, not some kind of treacherous person, because a large number of written records in the Shang Dynasty are oracle bone inscriptions, and the oracle bone inscriptions used in the early Western Zhou Dynasty are also very ordinary, but it is not impossible, because the ownership of the clay pot is actually only a small vassal state, and the exact point is just many uncivilized tribes in the Yellow River Valley.

We walked downstream along the river shoreline, and the topography on the bank proved that this strange sand river seemed to have a period of rising sand, and the rocks on the bank of the sand river were full of peaks and peaks, all as thin as sharp blade stones, which were indeed similar to those washed by the perennial current, but we knew that it was caused by sand.

It was very difficult for us to walk on its side, and for a long part of the way, we had to pass by sideways in a row, on the one hand, to avoid falling into the unknown depths of the sand river, and on the other hand, to be careful of cutting our ankles or cutting our wrists with blade stones.

I have been spending two hours in this high tension, but in fact I have only gone seven or eight kilometers forward, and the Shahe River does not go in a straight line, and the corners are simply more than the eighteen bends of the Yellow River.

We didn't know how long it would take to go down, and if we went up, it would definitely not be possible to return, so we were going to take a break here for the time being.

We carefully inspected the place, and finally found that there were no more blade stones like that, and we were not injured, but our clothes were not lightly scratched, and if we had added a few more knives, then we would probably be able to squat on the flyover.

I thought I wanted to sit down and rest, but I saw the fat man walking towards the other side with a flashlight, not only him, but even Manan seemed to have discovered something, and he followed soon after. I was a little uncomfortable leaving the light source, so I walked over with the old generation with a huge package, and then I found out by the glimmer that the old generation's clothes wrapped around Maitreya were not torn at all, but the clothes he was wearing were very badly torn, especially behind him, presumably in order to keep Maitreya from being damaged, so he walked on the riverbank path with his back against the rock wall.

After a few steps, I immediately noticed what caught the attention of the fat man and Manan, which was a pile of wooden shelves, and on the wooden shelves were several wooden boats the size of lifeboats.

I was shocked, and I said in my heart, is it true that I built a boat into the abyss? Before I could get there, I immediately asked, "Aren't these boats the ...... you say?"

Before I could finish speaking, Manan immediately responded with a denial: "No. ”

I wanted to get to the bottom of it, but he didn't stop to explain it to me, and walked straight up. There is no other way, I can't hold a gun to his head and let him recruit him, although he has done this to me, but after all, the two sides cooperate, each takes what he needs, and I have to take care of the overall situation.

When I got to the boats, I found that they were not old, but even very new, and the planks were a little whitish, and I could tell at a glance that they were made of poplar wood.

The poplars that we can see now basically appear either in the desert or on the Gobi, because they are dry and lack of water all year round, their trunks will slowly shrink, try to save water, so they cannot be used as wood. But at the beginning of the last century, Lop Nur began to slowly dry up, and the once oasis was completely a sea of death in less than 50 years, but before that, thousands of acres of poplar forests and large wetland oases formed an ecological zone on the edge of the desert. Moreover, there are fishermen in Lop Nur, and the poplar wood shipbuilding is not apocryphal, the few small boats in front of us are made of poplar wood, and their use makes me turn my head to look at the sand river on the other side.
