Lin Song used his shoelaces to wrap the two pads around his shoes, and then rushed to the front and began to sprint over.

When Lin Song climbed over the sand dunes again, Wu Meng only had his head on the sand left, he smiled at Lin Song, and said loudly: "Team leader! Don't waste your efforts, walk out safely with your brothers! Brothers are all counting on you! ”

Lin Song scolded: "I'm bah! You also know that I will take you out safely, if you die, will Lao Tzu not break his word! ”

After speaking, Lin Song actually ran directly to the front.

Zhang Feiyu and Zhao Hu next to them were startled, and the two of them just wanted to stop Lin Song, but Lin Song's speed was too fast, so they ran out directly.

Then, a miracle happened!

Lin Song's feet were on the sand, it could be seen that he was very hard, but he barely sag, Lin Song continued to run forward, seeing that when Lin Song approached Wu Meng, Wu Meng only had one hand left outside.

Wu Meng's hand gave a thumbs up, and at this scene, Zhang Feiyu and Zhao Hu who watched it had tears in their eyes, but Lin Song snorted and stood directly beside Wu Meng.

When I was running fast just now, although my body was sinking, the magnitude of the sag was not large. But when Lin Song stood still beside Wu Meng, his body suddenly sank in! In a few tenths of a second, Lin Song was like a sharp iron drill, and he suddenly plunged into the sand.

Lin Song had two hands in the depths, one hand snapped and dragged Wu Meng's hand, and the other hand was fiercely rounded, and he directly threw the rope to Zhang Feiyu and them.

Zhang Feiyu and Zhao Hu grabbed the rope as soon as possible, and pulled back with all their might, while Lin Song was frantically dragging Wu Meng. The harder Lin Song worked, the faster his body sank.

In the end, when Lin Song only had his chest left on the sand, he finally pulled Wu Meng's head out. Wu snorted, spit out a mouthful of sand, and then gasped deeply.

Snow wolf! Go up and help! Lin Song shouted.

The snow wolf didn't say a word, rushed up directly, grabbed the rope in his mouth, and pulled up with Zhang Feiyu and Zhao Hu.

In the end, Lin Song and the others were finally dragged out of the sand. Lin Song and Wu Meng were lying on the ground, not saying anything, not saying a word, just taking a deep breath.

After the two of them had evened out their breath, Lin Song asked angrily, "What are you doing!" Good to keep a vigil for you, why are you running behind the dunes? Peeing? Just stand on the edge of the camp to pee, you can't be shy! ”

Wu Meng shook his head: "Team leader, you misunderstood, I didn't mean that, I just wanted to find a water source, I heard the sound of water just now." ”

"You're crazy to take you!" Zhao Hu said angrily: "What kind of water flow, do you say you are stupid, where does the water flow come from in this place!" ”

Wu Meng said very firmly: "I really heard the sound of running water!" I heard it very clearly. You believe in me, since I was ...... After being transformed, my sense of hearing became very sharp, and I was sure I heard it right. ”

Zhao Hu still wanted to argue with Wu Meng, but he heard Lin Song raise his hand and say, "Don't speak!" ”

Lin Song immediately used the Qiankun Tuna method, which can greatly improve the function of a certain organ in the human body in a short period of time.

This time, Lin Song is using the Qiankun Tuna method to improve his hearing ability. When Lin Song's hearing gradually improved, Lin Song's face suddenly changed: "I heard it too!" ””

'What a joke! Zhao Hu said with a look of surprise.

Soon, the surprise on Lin Song's face turned into confusion: "No...... I can't hear it again! Yes, the sound was very faint, but we couldn't get it wrong. There should indeed be the sound of flowing water. ”

"Boss, you're not kidding us, are you?" Zhao Hu said.

Even Zhang Feiyu frowned and said, "Are you sure?" We're running out of drinking water these days, so you're having auditory hallucinations? ”

Lin Song didn't explain anymore, he turned his head to look at Wu Meng: "You listen to the direction of the water, from what direction did it start to flow?" ”

Wu Meng pointed ahead: "Those who came from that direction flowed straight in the opposite direction." ”

Lin Song nodded happily: "Let's go!" Sleep first, I probably know how to determine the direction. ”

"Boss, how do you judge?" Zhao Hu asked.

Lin Song pointed ahead: "Before leaving, you should have heard from the captain that the ancient city of the Yue Clan used to be a rather majestic city, and the number of residents in it once reached hundreds of thousands. In these small cities in the Western Regions, it is a very large ancient city.

Since ancient times, the castle has been built on the edge of the water source, which means that there was originally a river around the ancient city of Yueshi. ”

"There is a river? So what? Even if there were rivers, they would have dried up by now. Zhao Hu asked with some puzzlement.

Lin Song shook his head: "You are wrong, rivers never disappear out of thin air. The river on the ground is broken, it's not that the river is gone. However, after the soil is desertified, the ability to lock in water is reduced, and the original river water falls into the ground and becomes an underground dark river! For thousands of years, rivers on the ground may be diverted, but underground rivers are almost never diverted!

That's why the Gobi is so big, but there are quicksand traps here! If we follow the direction of the water and walk all the way forward, we will definitely find the ancient city of Yueshi. ”

"Wait! If there is an underground river, wouldn't it be easy for us to dig up the ground and dig out the water? Zhao Hu said in surprise; In this way, we will never run out of water again. ”

Lin Song shook his head helplessly: "From what we heard just now, it seems that this underground dark river is at least more than twenty meters below the sand. If a complete engineering team can be airdropped over now, within ten days, maybe the water of the dark river will be dug up. ”

The comrades-in-arms understood what Lin Song meant, and Lin Song said directly: "But now, it is very good to have a clue in such a direction compared to before, everyone work hard, hurry up." ”

Everyone hurried back, forced themselves to lie on the ground, squinted for a while, and waited until seven o'clock in the morning, when the sun had not yet risen, Lin Song woke everyone up, and the snow wolf group set off again.

In the next few days, Wu Meng and Lin Song's hearing played a very high role. Every once in a while, Wu Meng could hear the sound of underground water flowing. The crowd went in the opposite direction of the water, tracing the source.

The people continued on their way for two days.
