After returning at noon, they each came to the tent, all of them were in a state of disgrace, they walked in the scorching sun for several hours, most of them were red, slightly peeling, and looked very embarrassed, and it could be seen from their eyes that they did not seem to find any ruins.

"You've been walking for most of the day, but what architectural remains have you found? Or even just a few mounds. Song Siyuan looked at everyone and asked.

As soon as these words came out, everyone shook their heads, and the old herdsman Kuini said: "We walked directly to the vicinity of the Hotan River according to the direction you gave, and no traces of the ruins were found during this period, let alone what mounds were, not even the platforms of the Eight Classics, all of them were sand dunes." ”

"So do we."

The rest of the team also said in unison.

"What about you?"

Keli asked Song Siyuan.

Yue Guanchao shook his head and puffed up his teeth: "We have been looking for a long time along the way, and we really haven't found any ruins of the royal city, you have to say that we have found it in all four directions, if there are no ruins in either direction, is this Sand Sea Royal City really in another dimension?" ”

Everyone could only shake their heads helplessly, they really didn't have much information about the Sand Sea King City.

Song Siyuan sighed: "Otherwise, tomorrow we will each switch directions, maybe it's because we haven't looked too carefully, if we haven't found the ruins of the Sand Sea King City by tomorrow, it may really be as we guessed, the Sand Sea King City is likely to be in the mirror space." ”

"Okay, that's the only way to do it, it's all here, it's impossible not to make any efforts."

Song Siyuan said again: "I suddenly had an idea, is it possible that the Sand Sea King City was covered by yellow sand, could it be that their ruins are under our feet?" Rather than exposing the ground. ”

Her proposal made everyone's eyes shine, Yue Guanchao nodded: "What you said is also possible, after these yellow sand are blown by the wind, it is easy to form constantly moving sand dunes, the ruins of the Sand Sea King City have experienced thousands of years, and it is indeed possible to be buried under the yellow sand, you mean that we have to dig up the yellow sand to find things from inside?" ”

Song Siyuan nodded at everyone, she just had this intention: "Then let's try it, at least dig a few meters first, and see what is buried under this yellow sand?" ”

As soon as they said and did, Yue Guanchao took a few of Queenie's men, and soon found a slightly hardened sand nearly a hundred meters away from the camp, and they picked up the sapper shovel and dug the mud and sand downward, and after about an hour, they had dug five or six meters deep.

At this point, except for the slight wetness of the sediment, there was still no sign of soil, which showed that the accumulated sand layer in the hinterland of this desert was definitely not shallow, and they dug down several meters while the iron was hot, until they dug out a depth of more than ten meters.

Everyone stood on the edge of the sand pit, staring at the sand pit dug down, there was still no trace of any ruins, the buildings in the city should be made of rammed earth, since there is no soil, it means that it is still far from the ruins, or the ruins are not here at all.

They saw that there was still yellow sand more than ten meters underground, and they were completely dead at this moment, and they went back to rest at night.

After a night's sleep, Yue Guanchao woke up from a dry sore throat, he looked at the pocket watch in his hand, it was already seven or eight o'clock in the morning. However, the sky outside was not as clear as yesterday, as if it was a rainy morning, through the chaos and darkness, and even a low pressure that made the body extremely uncomfortable.

At the same time, it seemed to be raining on the tent, and the tent was shaking with the wind and sand.

Could it be raining?

Yue Guanchao rubbed his eyes, put on his clothes and got up and walked out of the tent, the sky was really as he guessed, there was no sunny feeling at all, the sun was long gone, and when he raised his eyes, it was like a fog-like yellow sand floating dust, in this brilliant and chaotic environment, he could also feel some whirlpool-like winds in the distance getting bigger and bigger, forming a dragon whirlwind that constantly swept away the wind and sand.

This tornado directly swept up the yellow sand and threw it everywhere, which aggravated the chaos of the environment, making people more and more unable to see the surrounding environment.

He thought that the sky would be raindropping, the moment he raised his hand, he saw countless grains of sand falling in his hand, and the direction had nothing to do with the wind and sand, it was completely falling from the sky, and then listening carefully to the movement, he could also find that the whistling wind came from the tornado produced by the sandstorm, and the wind blew through the tent, naturally causing a loud vibration, and it sounded like a storm from the tent, and the wind whimpered.

As for the dark and chaotic sky, it was the wind and sand that completely covered the original state!

After the old herdsman Queenie came out of the tent, he raised his hand, looked at the things that had fallen in his hand, and saw a handful of sand in his hand, and his face was suddenly awakened from fatigue, as if he was startled, and his face became panicked: "Sandstorms, tornadoes, dry sand and rain, not good!" We need to get out of here. ”

Yue Guanchao saw that the old herdsman's expression was abnormal, and asked curiously: "Uncle Queenie, it's just a little sand, don't be so nervous." ”

Regarding this point, it is obviously not as simple as Yue Guanchao understands, the old herdsman said in a panic: "Young man, it's not what you said, it's not terrible to rain in the desert, I'm afraid of the sand, hurry up and call everyone up, go to the top of the red and white mountain, go as high as you can, otherwise it will definitely be a big disaster, you believe me, and I'll explain the reason to you when you get to the mountainside." ”

Although Yue Guanchao doesn't know whether Queenie's words are true or false? But judging from his attitude, it was definitely not a good thing to go down to the sand, and he understood that he would take up the copper basin and knock it up, and wake up all the living people in the tent, and at the same time, they took up their bags and picked up their valuables, and before they even had time to collect the tent, they began to lead the camels towards the Red and White Mountain.

Fortunately, the camp where they were stationed was only two hundred meters away from the Red and White Mountain, and they had already walked over after a moment of leading the camel, during which they would inevitably be attacked by the surging tornado quicksand, if it wasn't for the weight of the camel, they would have been swept into the sky by the tornado, and they didn't know whether they were alive or dead.

After experiencing the current situation, they were also able to see how terrifying the desert is under the sandstorm?

In general, these dunes are usually still, like layers of intricate scales, and when the dust storm rises, the quicksand is like a hill that can move, and under the wind blowing, it is like waves in the ocean, constantly squeezing in the direction of people.

After leading the camels up the Red and White Mountain, they galloped all the way up the mountain road until they reached the highland slope halfway up the mountainside, and then they came to a complete stop.

This position is not too high, only climbing a third of the mountain, but fortunately, the terrain here is hundreds of meters higher than the desert, and it is a completely hard stone mountain, after staying away from the sand, the moving sand dunes will not threaten their existence, plus standing high and seeing far away, it is clearer, and it is more clear what is happening in the sand dunes below the mountain?

At this moment, they are hiding in the grotto on the mountain, and at a glance they can see that the sand dunes below the mountain are like boiling yellow soup, constantly rising and falling, shaking left and right, and every time they move, the sand dunes will change their order and direction, although they are still arranged in the form of fish scales, the size and height of the dunes change violently in the trembling, and every tremor of the sand dunes is constantly devouring living things, plus the tornado rolls up the sand everywhere and falls to the ground, it is not surprising that it is a violent rain.

It was so dangerous, they still escaped in the end, and the old herdsman Queenie was not a little relieved until he entered these abandoned grottoes.

"Uncle Queenie, can you tell us about the dangers of the sand rain now? I look at you like this, you seem to be afraid of these sand rains, and I don't think it's that dangerous, isn't it just a little sand from the sky? ”

Yue Guanchao's words provoked the old herdsman to wave his hand frequently, and retorted: "If it rains an ordinary rainstorm, it is not a big problem, the most feared thing in the desert is the sand rain overhead, do you know what the sand rain is?" ”

The so-called sand rain refers to the sky that falls to the ground is no longer rain but gravel, sometimes even rain mixed with gravel to form the mortar, the cause is related to sandstorms, in sandstorm weather, tornadoes violently swallow clouds and spit fog, in bad weather, directly roll the sand and send it into the clouds, and then fall to the ground by the weight of the sand, as if it rained, which is called sand rain.

The danger of sand rain is because the amount of sediment that is swept into the air is very large, and when the brain is tilted into the ground, it is easy to drown people and animals, and directly smash on the surface of the desert.

At this time, it is very difficult for the living to come out again, and the sand will continue to squeeze their bodies and facial features until they drown alive in the sea of sand.

It is equivalent to saying that although the sand rain is not rain, it is indeed more terrifying than the flood, and it deserves to be like a flood beast, which makes people frightened and avoided.

As they spoke, they looked at the place where they were stationed, and the camp, which had been located on the tidal flats, had been largely submerged in the yellow sand, and only a section of the tent on top of the tent was exposed, like a small dirt bag stuck in the sand, and if they had gone a little later, they would have been buried alive.

Under the thrill, everyone only felt that their legs and stomachs were swinging, and they escaped death again.

Halfway through the sandstorm, there was a real storm in the sky, like a downpour into the sea of sand, which was quickly sucked clean by the accumulated sand, and the sand quickly became dry, like a huge funnel, falling rainwater into an underground river they didn't know about.

The Red and White Mountain, where they are located, is not affected by the sand and soil, and the rain falls on the ground and is quickly dried by the high temperature, but it is even hotter than just now.

For them, before they saw the desert monsters, they had already seen the desert celestial phenomena abnormal, and they were almost drowned by quicksand, which was already extremely terrifying.

As the sand rain gradually disappeared, the sky gradually returned to normal, and then, Song Siyuan observed some situations and became curious about these special situations - the desert near the Red and White Sacred Mountain, some sand lands are very dry without stagnant water, and some sand pits have accumulated a lot of rainwater, forming a lot of ponds, forming a patch-like distribution of dry and wet tidal flats under the Red and White Mountains, this situation is obviously abnormal!
