Wei Ruyu followed and looked closely, where were the traces of the heavy rain outside? Not to mention the puddles, except for the occasional little trace of water on the leaves of the sparsely fallen feathered plants, there was no moisture on the ground at all.

After a while, the breeze returns, and the sand gently jumps with the wind.

This......

What about water?

Where did the water go for such a big rain?

Wei Ruyu doesn't believe in evil, and wants to get out of the small courtyard and go outside to feel the water aura.

Before and after heavy rain, it should be the time when the water aura is most active. No matter how abnormal the environment of the desert is, as long as the rain just now is not an illusion, the activity of the water aura in the air cannot be faked.

Ye Junze did not stop him, closed the protective shield as kindly, and let Wei Ruyu walk out of the small courtyard, closed her eyes, and carefully felt the surrounding environment with her delicate divine sense.

The water aura in the air was indeed more active than when they first entered the desert. However, it is far from the level of activity that should be there after normal rains.

Even, this little bit of activity is passing in a certain direction at a rapid pace......

Wei Ruyu's divine sense followed, and it was not difficult to find that the sandy soil on the ground, which was still wet, was rapidly losing water, and the water was rapidly infiltrating downwards and infiltrating along the excessively loose gaps between the sand......

"That's the nature of the desert. Ye Junze smiled, obviously knowing more than Wei Ruyu, a temporary crammer. "A lot of people think that deserts are formed because of drought and lack of rainfall. In fact, drought is real, but lack of rain is not. ”

Especially in the summer and autumn like these, the Death Desert is in the rainy season.

Although it cannot be said that it rains every day, the amount of rain is actually more abundant than 100,000 mountains.

Pointing to the bottom, Ye Junze motioned to Wei Ruyu. "Do you remember the remnants of the [long-along] underground river that we met earlier in the 100,000 Great Mountains?"

Wei Ruyu nodded.

"Here, there is also a dark river underground, and the water system is not more developed than the underground water system of the 100,000 mountains, and the water source is abundant," Ye Junze checked a lot ......of information in the bookstore yesterday.

Although many of the materials are incomplete, or because the ancient fonts are not the same as those commonly used in the Xiuzhen world today, even the owners of the bookstore may not recognize what is written on those books. But Ye Junze has a lot of experience, but he has found a lot of useful secrets.

If it was millions of years ago, before the sudden and unclear change that no one could tell what happened, the turn of summer and autumn was the season when the water and grass on this plain were the most fat, and it was also the season when all kinds of demon beasts and spirit beasts were active, and the spirit grass and spirit plants were piled up and ripe.

It is precisely because of the fertility and richness of this plain that there is even an underground spirit stone vein buried here back then, that the monks of the year would gather here and establish a city-state.

Even, even if there is no sect, it can still tightly unite a group of monks from all over the cultivation realm.

However, it was the vast plains of a million years ago, a normal, ordinary, yet thriving land, not the expanding and depleting deserts of death that we have today.

Nowadays, the soil of this land has been completely destroyed, and the land in the Dead Desert has been completely desertified, and the loose land cannot retain a little water at all.

No amount of water can survive the gaps between the sand that are too loose. Naturally, no matter how much rain falls, it will seep into the ground along the cracks for the first time, quickly flow into the underground river along the cracks, and then rush away with the thriving water system underground, without the slightest nostalgia for the sand and environment on the ground.

The moisture in the air will also evaporate at a very rapid rate due to the rapid loss of moisture from the ground and the rapid increase in temperature in the desert after rain.

Even the Gobi Desert, which has not yet been completely desertified, now looks much better than the desert, but it is only a matter of time before it becomes like this. On the Gobi, compared to the vast desert, the rate of rain loss may be a little slower, and there will be more animals and plants to survive, but the essence is the same.

Therefore, there is little greenery in the desert, except for a very small number of lakes that are able to form a seasonal season because the ground is not completely desertified, or where there are occasional puddles of water where dark rivers are outcropping, and large and small oases that depend on these large or small, stable or seasonally changing water systems, and smaller than the oases, which are dotted with desert plants.

On the contrary, those monster beasts in the desert are more flexible, more adaptable to the environment, and can also compensate for water by eating desert plants when necessary, so their vitality and range of activities are more popular.

Of course, drought in the desert is not absolute. In the season when it is not the rainy season, the flora and fauna in the desert also have their own way of survival. During the day, the entire desert is arid and presents a state of extreme water shortage.

However, because of the existence of the underground water system, the water vapor steaming under the scorching sun, when night falls, the special condensation method of desert plants will gather the condensed water vapor in the environment.

The environment here may seem harsh, but it has its own wonderfully weak balance.

Therefore, it is not so simple to change the environment of this desert.

Otherwise, the Badaomen and the Death Desert have been neighbors for 10,000 years, and they would not have been able to just stare at the Death Desert as they expand their territory day by day, but they would not have the slightest solution.

Wei Ruyu nodded, with a thoughtful expression, and he didn't know how much he listened.

Ye Junze finally succeeded in winning a game, and he didn't care what Wei Ruyu was thinking, he patted the top of the little girl's head gently, and let the little girl ponder by herself, he turned around triumphantly to find the two brothers who were visiting and sighing in the house without heart or lungs.

The little girl is a lost age, and she is still a person who has never been out of the house, and she wants to compare her understanding of the peculiar geological environment with him, Jin Dan, who has been practicing outside all the year round?

It's just that he, as an older brother, let her!

Although the rain has stopped, it looks like it's getting nice outside, and people are very impulsive to go out and enjoy the scenery, but in fact it's already evening, and it's only a blink of an eye before night falls.

Ye Junze was not so mad that he asked everyone to rush overnight, but just called the two brothers up, and the three of them discussed the arrangements for the night, and each ate something, and Ye Junze, who was arranged to be on duty in the second half of the night, went back to the room and fell asleep.

Well, he, Young Master Ye, is a big man, he used to be too lazy to bother to engage in this kind of portable cave mansion when he was traveling abroad, and it was the first time he used this thing, of course, he had to give priority to feeling it. However, there is no need to tell this little secret in front of the little girl.

Let the little girl feel that he Young Master Ye is rich and lazy about pleasure, anyway, he is such a person.

Wei Ruyu's children's family, of course, has no night arrangement. even gave her and the little monkey a separate room, Ye Junze was next door to Wei Ruyu, and the Hu brothers were squeezed into one room.
