"What are you talking about...... I don't understand. ”

Keli didn't know the story of Yin Yang Yu Pei in advance, and at first glance, it was even more foggy, and his face was full of suspicion.

Song Siyuan saw that Keli didn't know anything about this matter, so he first introduced him to the origin of the Yin Yang Yu Pei, and told them all about their experience of finding the Xuanshu Iron Coupon and the Yang Yu Pei, these things are related to the Yin Yu Pei, but they are independent, Ke Li didn't mention anything else for the time being, only knew that the Yang Yu Pei and the Yin Yu Pei were originally a pair, the emperor from the Zhou Dynasty, before they came, they had already obtained the Yang Yu Pei, and the Yin Yu Pei was left in the hands of Queen Shanshan, which brought the trip to the Western Regions.

In the process, Song Siyuan omitted and selected several times, and would not introduce it in such detail, Keli had already heard them discuss Yu Pei one after another earlier, and combined with what they just said, they finally got a clear context.

Keli nodded and said: "If you say so, we will understand the general process, do you think that this Yin Fish Pendant, like the Yang Fish Pendant, can create some non-existent enchantments out of thin air, as if the oasis and the royal city were covered up, and the desert they saw was razed to the ground, but in fact, only the oasis was completely covered, not disappeared in place." ”

Nicky couldn't understand the concept of mirror space, but luckily there were myths about shielding things, and the word enchantment was the most similar to what they said.

Song Siyuan nodded at him: "It's really similar to what you understand, but it's slightly different, of course, we won't discuss the difference anymore, we can only guess that the underground royal city is hidden in other places, and if you understand it in this way, it corresponds to the divine power of Yin Yu Pei." ”

The mountain forest space of Shennongjia like a labyrinth, even if it is still the appearance of a mountain forest, has actually been opened up by the mirror space created by Yang Yupei, as if a transparent labyrinth was forced in the mountain forest, as long as you can't find a way into it, you will definitely not be able to enter and exit, and you will be trapped in it.

As for the many illusions created in the mountains and wilderness, they are also the specific manifestations of different hexagrams in different directions, and together with the labyrinth, they render the depths of Shennongjia like a ghostly space, completely unpredictable.

They stood on the highest terrain of Shennong Peak, and they couldn't find Tiantong Peak at all, it was precisely because of the mirror world created by Yang Yupei that the ghost world, including Tiantong Peak, had completely hidden in the mirror space.

In the same way, Yin Yu Pei may also have such a function, which can directly open the passage of the real world and the mirror space, and hide the entire Desert King City, this drastic process has attracted the sandstorm around the King City and the shaking of the ground, in the eyes of ordinary people, it is like Queen Shanshan urging divine power, making the Sand Sea King City completely submerged by the desert.

Speaking of this, Song Siyuan's eyes lit up: "Then, the desert becomes an oasis and the Ganzesheng River water, can it also be understood that Yin Yupei folded a part of the desert space, and directly let the oases and rivers in the desert appear in the area that was originally a wasteland, thus forming the magic of the desert becoming an oasis and the Ganzesheng River." ”

She paused and continued to explain: "I remember that Bai Hua mentioned in the booklet that even if there is such a thing as a fish pendant, it only helped the Shanshan Dynasty extend the life of the oasis, and did not change the fate of the oasis, these oases will still disappear, I was still curious before, why even if there is a fish pendant to maintain the oasis, the Shanshan Dynasty still perished, now look, the crux is on the fish pendant." ”

Song Siyuan mentioned this and picked up the teapot that Nayi put on the table: "If the teapot is compared to the total area of the oasis, then this cup is an oasis folded by Yupei, every time we pour water, the water in the teapot will decrease, and at the same time, the water in these teacups will be drunk by us, and every time we drink a cup, the water in the kettle will decrease a little, until the last drop of water in the kettle is poured into the cup, and the water is completely drunk by us." ”

The oasis disappears, and the situation is similar to pouring water from a kettle!

The oasis is produced by water sources and rivers, in the case of desert drought, the total area of the oasis must be relatively constant and decreasing compared to the desert, in this case, the kettle is the oasis in the desert, the cup is the ancient Shanshanguo, these water that is constantly poured into the cup, is the oasis created by the fish in advance.

No matter what Yu Pei does, he is folding the space, folding the oases that were originally located in various parts of the desert into the vicinity of the city-state, it seems that there are more oases near the city-state, but in fact, the oases in other parts of the desert are used by them in advance.

With the total number of oases relatively constant, once the oases are used by them, they will cease to exist with the invasion of wind and sand in the context of climate upheaval.

In this way, the many city-states of the ancient Shanshan Kingdom are like cups that are constantly consuming the oasis, and those oases created by them out of thin air are overdrawing the oases everywhere in the desert in advance.

As long as they have the perspective of God and see the whole desert as a whole, they can find that the oasis in the desert is converging towards the Shanshan Dynasty, just like pouring a teapot to get water.

This stock will disappear one day, just as a teapot will run out of tea one day.

This node is in the late period of the Northern and Southern Dynasties.

The number of oases recorded in the white birch booklet is becoming less and less, which is a sign that the total number of oases has been depleted, and after that, no matter how much Yu Pei urges his strength, he can no longer maintain the oasis, and how can a teapot without water be poured out of water.

The ancient Shanshan Dynasty was equivalent to a farmer who fished in the dry water, directly consumed the oasis, and finally, finally could no longer maintain the oasis, so the whole country could only move to the vicinity of Hongbai Mountain, and build another Sand Sea King City here.

"No, if the area of the oasis has been exhausted, how can Yu Pei create an oasis out of thin air in Hongbai Mountain?"

Yue Guanchao understood that Song Siyuan's guess was very reasonable, but the part about the Sand Sea King City was really not easy to explain.

She was already aware of the problem of the Sand Sea King City, and continued to explain: "As I said earlier, the oasis is nourished by the river, and you can understand that the existence of all oases consumes water resources, and the ancient Shanshan King City consumes water resources from other places. ”

Looking at it this way, the reduction of the Mirandze and the diversion of the Peacock River are basically because the ancient Shanshan Dynasty used the water resources in the desert, which made them divert and dry up, and the water sources that were supposed to nourish the desert were consumed by them within two hundred years.

From this point of view, it is logical that the drying up of Mirandze and the diversion of the Peacock River are logical, and the drying up of this thousand years is because most of the water was used in advance as early as the Northern and Southern Dynasties.

She paused and continued: "The oases in the desert mostly come from the Kunlun Mountains and Tianshan Mountains in the north and south, and because of this, even if the oases in the desert are exhausted, there can still be oases on the north and south banks of the desert, and it makes sense that these small coastal countries are not affected. ”

"And what the Shahai King City borrowed is the water veins that extend from the Tianshan Mountains and the Kunlun Mountains."

Song Siyuan's eyes flashed with brilliance, pointing to the map hanging on the wall, signaling them to look at the vicinity of Hongbai Mountain, which is close to the Hotan River, this Hotan River runs north-south, and the north stretches out from the Tarim River in the Tianshan Mountains, passing through the desert, connecting the Hotan Oasis under the Kunlun Mountains, which is a river nourished by the Kunlun Mountain and the Tianshan River.

She explained solemnly: "When the Milanze dried up, the Peacock River was diverted, and the area of the oasis continued to shrink, and the fish and pendant prompted the oasis, which in turn exacerbated the drying up of the river Daze, and after the oasis near the desert was consumed by them, they crossed the desert to the Red and White Mountains. ”

"If it weren't for the Sui and Tang dynasties, Queen Shanshan made the royal city disappear, then the oasis of the Hotan River is very likely to be consumed by the ancient Shanshan Kingdom, and at that time, even the oasis along the desert will not exist."

Song Siyuan said this, her guess basically deduced the disappearance of the oasis of Shanshan Ancient Kingdom, and everyone looked at the Red and White Mountain, and they also understood the reason for the disappearance of the Sand Sea King City - it was connected to the mirror world by the fish, or folded, or directly sent into the mirror world.

Yue Guanchao nodded: "Then, when are we going to Hongbai Mountain?" ”

Since they understand that the Sand Sea King City is still in the Red and White Mountain, then they must go there, and it depends on how to get to the Red and White Divine Mountain.

"When we go, the key is how we go, we can't cross the devil's desert like them, right?"

Xu Xiake looked at Dunhuang where they were, they had experienced so much suffering in the past few days, and they only came from Dunhuang to Mirandze, and from Dunhuang to the desert of Mirlan City, the straight-line distance was only three hundred kilometers, and it was only about six hundred miles at most.

If you cross the Devil's Desert from Dunhuang, there are at least 1,100 kilometers from the map, and the straight-line distance alone is more than 2,200 miles, which is still the crooked road they actually have to walk halfway.

"Kelly, how long did it take you to cross the desert?" Yue Guanchao asked.

Keli recalled the past and said: "I used five camels, prepared enough water and food for two or three months, and it took a month and a half just to walk through the camels, which was only me and Abba two people, very economical consumption can be done, so many of us, if we really have to walk for a month, just carrying water and food will have to more than 30 camels, this is still not any dangerous situation, if there is any danger, it will be prolonged." ”

"With so many people, it's hard to be safe."

Speaking of this, Keli shook his head: "This time we went to Mirran City, we lost a camel, my friends are very angry, even if you lose money, they are also very angry, it is estimated that they will not lend us camels to cross the desert again." ”
