However, Wen Zheng remembered the general direction. This low-lying area was located to the west of the oasis. Although they had no hope, the three of them packed up and tried to return to the oasis on camels.

"Is there nothing? This oasis must have been submerged by the sandstorm.

"Huang Li said in a low voice. The camp they finally established disappeared like this, and they had to embark on a journey to find water sources again.

Wen Zheng stood on a tall camel and could see farther.

The camel had already walked the distance he estimated, but there was only a long stretch of yellow sand around, not even a speck of green.

“Let’s leave here and go to the plains to the north.

Wen Zheng said, and Professor Huang, Huang Li and others all agreed.

The group rode their camels silently toward the north.

Although they didn't know how long it would take to reach the plains, the drinking water they carried gave them enough confidence and less anxiety.

Wen Zheng's preparations finally came into use. Except for the kettle that was poisoned by Wang Zhiyuan, all the kettles were filled with drinking water.

Not only that, there are also cactus in the desert. The pulp inside is hollowed out and made into water storage containers. There are also skin water bags made from the skins of desert kangaroos and antelopes. They are all placed on the backs of camels and they follow them. Go far away.

The camel bells rang softly and the dust rose lightly. Six camels were walking in the desert with three people and various supplies.

Under the scorching sun, you can feel the heat entering your body with every breath you take, and even the air becomes distorted due to the high temperature.

After spending the most difficult time at noon, they wasted no time and got up from the sand and mounted their camels.

After leaving the camp, they began to move around day and night again. They felt the heat during the day and the cold at night. They just walked without knowing what they would be like in the future.

"Although the scene in the desert is quite spectacular, after watching the same scene for more than a month, no matter how beautiful the scene is, it has become boring. If this continues, I will develop yellow aversion, especially when seeing yellow. The yellow sand makes me sick to my stomach.

"Huang Li sat on the camel and complained softly.

"Close your eyes if you don't want to see it. I see that you are quite energetic and have the energy to complain.

"Wen Zheng said with a smile.

The camel was walking on the top of the long sand dune. After listening to Wen Zheng's words, Huang Li obediently closed his mouth, then closed his eyes to rest.

The temperature gradually dropped, and the comfortable evening was approaching. Professor Huang was shocked when he observed the surrounding terrain. He saw a strange scene in the distance.

Thinking of Huang Li's complaints in the afternoon, he couldn't help but smile, turned around and called Huang Li awake from behind: "Huang Li, get up and take a look, have you seen the scene over there.

"Hearing this, Wen Zheng followed Professor Huang's direction and looked over.

Wind-eroded mushrooms.

Chapter 136 In the desolate gravel area, there are many isolated columnar rocks. Different from the rocks you usually see, these columnar rocks have strange shapes, big at the top and small at the bottom, like giant mushrooms.

Therefore, this peculiar rock is called wind-eroded mushroom, also called mushroom rock. It is an extremely rare natural landscape.

The formation of wind-eroded mushrooms is of course related to wind. Layered rocks collapse during the weathering process. The softness and hardness of each layer of rock are different, and the intensity of wind blowing is also different. The columnar rocks carved out by wind and sand gradually become It has a mushroom shape with big top and small bottom.

This process takes hundreds, thousands or even tens of thousands of years to occur. It is a great miracle of nature and a rare spectacle.

"Nature itself is the best sculptor. It is truly a miraculous workmanship. What a wonderful and spectacular sight.

"These mushrooms are really big. Now I have material to tell stories to the children. It's a pity that I don't have a camera to take pictures."

"Don't you dislike the sameness of the desert landscape this time?" " Huang Li giggled, looking at the spectacle in front of him in shock, his eyes full of wonder.

Wen Zheng and others stayed here for a while, silently remembering this scenery in their minds, and did not go down to see it up close.

These wind-eroded mushrooms are not as small as real mushrooms. These mushrooms made of rocks are extremely tall, and because they have withstood long-term wind erosion, they are not particularly strong. If you are unlucky and encounter rock fragments after going down, you will be hit. Not so good.

After admiring these wind-eroded mushrooms, Wen Zheng and others left this special area and continued on their way.

In the blink of an eye, Wen Zheng and others walked for several days after leaving the oasis. After passing through the area with columnar rocks, the terrain around Wen Zheng changed from a long stretch of yellow sand to a rocky desert with a large number of exposed rocks. There were many obstacles on the road. Lots of exposed boulders.

After trying to save as much as possible, there was still about a quarter of the drinking water left, which was enough for them to travel for a few more days.

Wen Zheng silently calculated the time in his mind. During a conversation with Professor Huang, he suddenly remembered that the time chosen by the expedition team when they came to this desert was autumn, which is the earth month, and now they are about to reach the end of January. , if they follow the survival time given by the system, they still need to spend the month of February in the desert, which is winter when the nights are colder.

Although after meeting Wang Zhiyuan and Yang Liu, Wen Zheng had a thick coat that could keep him warm late at night, but it was really difficult to spend the month of February safely.

There are too few materials available in the desert. Wen Zheng now hopes to encounter some wild animals and make a fur coat. If that doesn't work, he can only kill the camel.

While Wen Zheng was thinking about this problem, he raised his eyes to look at the surrounding terrain, hoping to find edible plants or animals again.

Suddenly his eyes focused on a green, low-lying terrain.

Wen Zheng squinted his eyes and looked carefully, and regretfully found that this was not like an oasis, but more like a salt-alkali land.

"Salt-alkali land? Brother Wen, how did you tell that it might be an oasis?" Huang Li shouted, with an excited smile on his face, and he was about to ride a camel there.

Wen Zheng shook his head, pointed to the plants in the distance and said: "Those green and some red succulent plants are called salina. They are a very salt-tolerant plant that grow in saline-alkali land.

"The desert area does not mean that there has never been a water source. Maybe a long time ago, the saline-alkali land was a lake. However, due to the expansion of the desert area, the death of plants, the precipitation decreased, and the temperature increased. The lakes were not replenished with new water, and the original water was lost. Gradually evaporated, and finally the lake turned into a saline-alkali land with extremely high salt content.

Huang Li didn't know much about desert plants, but Brother Wen, a biology major, said so, so he was sure that it was not an oasis, and he suddenly became frustrated.

“The salt in the saline-alkali land is not edible, and we don’t have the relevant equipment.

Brother Wen, can this salthorn grass be eaten? Huang Lifa asked.

“The soil in the saline-alkali land is extremely salty, so it is not suitable for animal life. Only some mosquitoes live in it and like to move on plants.

We still have enough water and plants for a few days, but we still can't get through it. Those mosquitoes are hard to guard against and may carry germs.

" Wen Zheng opened his mouth to explain, dispelling Huang Li's view that he wanted to go there.

Huang Li's depressed mood lasted until night. When night fell and the temperature gradually dropped, they got off the camel's back and used the stones that had not dissipated and the camel's body temperature to keep warm.

After his feet touched the ground, Huang Li said hello to Wen Zheng and others, preparing to go to a distance to solve personal problems.

Wen Zheng and Professor Huang suffered from gum damage and some gum pain caused by internal heat.

After eating these meat queens, Wen Zheng picked up the kettle and was about to take a few sips when he heard Huang Li running back. Before he could worry about whether Huang Li had encountered something, he heard his slightly panicked shout: "Brother Wen , I found a few bones that looked like human bones.
