When he said this, I remembered that there were blood butterflies chasing after our butts, and this place could not stay for long, so I pulled up the forest and hurriedly walked into the river, and the little master followed us and chased after us quickly.

The river is very wide, and it is not a problem to pass two large trucks side by side, and the cracks at the bottom of the river are intertwined with each other, extending all the way forward in a lattice-like shape, and I can see that some of the cracks under my feet are more than ten centimeters wide, and it is more than enough to put my feet in, and from here I can imagine how precious the water source of Tengger was at that time.

If the place where we stand is placed in the past, it is definitely turbulent, the undercurrent is dense, guarding such a huge river, the golden city dominates Tengger is also forgivable, seeing the cracked river now, my heart is full of emotion, at that time I don't know how many people and how many countries have died in chaos, living in the desert, no river is exhausted, almost can cut off a country, I can't figure it out, people go to high places, water flows to low places, even the ghost head flower roots know to the place where there is water, Can't those who are short of water look for other sources of water? Do you have to die of thirst?

Lin Zi told me that he also thought about the same problem at that time, but in the end he knew how difficult it was to find a suitable river or oasis for his survival in the vast desert, not to mention the relocation of his family, running all the way with his wife and children, and he might have died on the way before he found the lake oasis, these people have lived in the desert all their lives, and they are still unknown to the outside world, besides, as long as there is water here, they are strictly guarded by the occupiers, and outsiders are not allowed to set foot at all, besides, The lake or oasis here will change at any time due to the changes in the water flow of the underground river, it may be a lake today, and it will dry up tomorrow, in the face of a complex and changeable environment, it is not yet true that a river has been guarded, so the Golden City will develop so much at that time.

The little master squatted down and pointed to the ravine beside the river that was washed out by the undercurrent and said to us: "Do you look at these two marks, do they look like wheel prints?" ”

Hearing him say this, I also squatted down, and found that there were indeed several special water flow gullies next to the river, the bottom of these two ravines was boxy, and there were irregular depths and shallow parts in it, and the sand next to the ravines was also uneven, which was not the same as the real water erosion, I also carefully observed several ravines around, and found that their depth and length were very natural, and even the arc could see the traces of time.

"According to my thoughts, they must have looked for water when the Ba River dried up, but in the end they didn't find it extinct." Lin Zi said.

"Not necessarily, you come and take a look at these rivers, I guess they must not have looked for new water sources at that time, as a ruler, he should know that even the Ba River can be dried up, which means that there must not be many oases left in the desert, although the country is very small, but to relocate the whole country, it will still face great difficulties and obstacles, according to what I think, the Golden City at that time must have been relocated to the underground Ba River."

In my opinion, the little master's idea is more reliable, but Lin Zi still has questions, he asked: "Moved into the Ba River channel, then how did they get in?" ”

"You don't know, Tengger's geology is relatively hard, although the sand dunes on the surface of the desert often move, but its underground is very solid, the dark river keeps flowing underneath, it will gradually rush out of a river channel, when the Ba River is exhausted, it will be washed out of the river channel will become empty, at this time, the remaining water will be sucked dry by the desert, the sand after the sucking up, like a wall, plays a role in supporting and protecting the river, and because the river is too deep from the ground, so its appearance has been preserved to this day."

"You mean, there is a hollow river underground in Tengger now?" Lin Zi asked with a look of disbelief.

"Yes, that's just my guess, and there was a group of people living here before the river was completely depleted......"

"So are these people from the Golden City?" Lin Zi didn't wait for the little master to finish speaking, and asked again.

"It's very likely that they must have found this place through a special method at that time, so they moved the whole country."

"Then according to what you said, the aisle just now ......" Lin Zi looked at the darkness ahead and asked a question.

"Yes, not the entrance." The little master took out the water bag, took a sip of water and continued: "I also just thought that the aisle behind us must have been directly transformed by the new city lord using the river, we can imagine the aisle as a dividing line, it divides this place into two sides, one side is the warehouse, the other is the residence, if my guess is correct, there must be another underground ancient city in front of us." ”

"If it's another ancient city, then we have to go through the ancient city until we reach the end of the river before we can get out?" Lin Zi asked with a worried face.

"Not necessarily, the river is so long, when do we have to go? You think, so many people live here, isn't there an exit closer to the ground? Don't be discouraged, there will be other ways. The little master replied slowly.

"Let's go, let's take a look." Lin Zi took the water bag and took a sip as well.

"Since I'm going to take a look, I have to see it clearly." I pulled out a small searchlight from my backpack, and to be honest, I really wanted to see such a huge underground ancient city.

But what I didn't expect was that we walked along this river, and walked for more than three hours, and the one who told me how long I walked was the headlamp on my head, which was assembled by Lin Zi and I before entering the Golden City, as far as I know, after dismantling, its power can support up to four hours, but now, it is out of power.

The watch and compass have long since failed, so we don't know where we are going now, only that we have heard that the Ba River runs through Tengger from east to west, but along the way I found several forks, from which we analyzed that the Ba River has changed direction.

It was pitch black in the river, the front and back were the same, and we drew a mark on the right hand side every time we walked a section, for fear of taking the wrong road, but even so we still didn't dare to turn around easily, because we were afraid that as soon as we turned around, we couldn't tell whether we were going or going.

After walking for more than ten minutes, I couldn't hold my breath, even I wondered if we had made a mistake, and at this time I only heard Lin Zi scolding: "Damn, will we meet a ghost hitting the wall, don't go, stop first to discuss countermeasures." ”
