Asking Immortals: From the Republic of China to Marvel

"Judging from the dry rivers we passed through when we came here, the situation here is still deteriorating, and judging from the several layers of lake beds in the small lakes that have dried up, we can conclude that the salt marsh has gone through several times of water gain and loss. .”

"What does this mean?"

Li Andai, who was drooled by Naan, asked again. He didn't understand what Daniel was talking about. Others also expressed doubts.

Because the turbulent flow dries up, and the rainy season or sudden high water fills the lake, this situation is quite normal. At most, it is just that the interval between salt marshes is a bit longer.

Upon hearing Li Andai's inquiry and the puzzled looks from the people around him, Daniel smiled slightly and waved his hand, indicating that he should be patient and allow me to speak slowly.

"It is indeed common for water bodies to wax and wane, but the obvious faults in the lake bed here indicate the long interval between two dry spells, which is very unusual."

As Daniel spoke, he paused and looked at the staring expressions of the people around him. After enjoying the satisfaction of being in the spotlight, Daniel continued:

“So I have a bold guess: Could it be the result of periodic sedimentation and uplift of the lake bottom, coupled with reduced wind erosion?

Of course, this is just a guess before seeing the main lake, but you can really imagine this, unless you have a better explanation. "

After hearing Daniel's words, everyone fell into deep thought and couldn't help but start to consider the authenticity of the speculation. Only Ye Zixuan gasped at this.

Because when I came from Luobu Nur, all the Gobi, deserts, wastelands, etc. I encountered along the way, I had used my spiritual sense to feedback the vibrations of everyone's footsteps.

The land here is so solid that even in that part of the desert floor, a few meters below are saline-alkali strata. Such stability makes it impossible for the terrain to change for a while.

What periodic deposition and uplift? I gave you a shovel and asked you to dig in place, but you couldn't dig it... so the reduction in wind erosion is a reasonable reason.

If Ye Wentian had been present, he would probably have slapped Daniel in the face and told him that the salt lake is the lowest point and catchment area of ​​the Tarim Basin, and it is impossible for the lake water to flow back.

Even if there really is any periodic sedimentation and uplift, can it be deposited and uplifted one or two kilometers high? Even if the continental plates drift, they will only drift about a hundred meters in two thousand years.

Historical records of the Han Dynasty record that Yanze is "three hundred miles wide, with water pavilions that do not increase or decrease in winter or summer." At that time, there were still more than 20,000 square kilometers. How could so much water flow back? Over mountains and ridges? You are shouting "Come on" from behind, Ollie is here?

"Professor Daniel, I think it's better to be more rigorous."

Seeing that everyone was deep in thought and some were fooled by Daniel's words, Ye Zixuan couldn't help but give a reminder.

"Science does require rigor, so I said it was just a bold guess~"

"..."

Hearing Daniel's reply, Ye Zixuan felt a little speechless. If no one refutes it, you will probably have to lead the rhythm of the backflow theory.

Everyone around him came to his senses after hearing the words, secretly guessing that they were just guesses and could not be counted, but the theory of the lake's reverse flow also took root in their hearts.

……

An hour later, everyone who had eaten and drank enough had entered the tent early, leaving only the chirping of insects and the howling night wind outside.

Ye Zixuan, who was squeezed together with two girls, was not convenient for practicing, so she had to go to bed early. Ye Zixuan, who was not sleepy, was closing her eyes when she suddenly heard several consecutive sounds in her ears:

"Ouch~owoo..."

"Professor Ye, there are actually wolves here?! Will we be used as food?"

"So scared~"

Of course, other people could hear such noises. The two girls next to them had solemn expressions on their faces, a little worried that something might happen at night. There were also commotions and whispers in other tents.

"Professor Ye? Professor Ye!"

"Who?"

Ye Zixuan was about to speak to comfort her, but before she could speak, she heard a call coming from outside the tent, and couldn't help but subconsciously ask a question.

"It's me, Zhang Yuping."

"What's wrong? Professor Zhang?"

After unzipping the tent, Ye Zixuan stuck her head out and asked in confusion, because she saw Zhang Yuping wearing cotton clothes and holding two long daggers in his left and right hands.

"Did Professor Ye hear the wolf howl just now? It's not peaceful here at night. I'm here to bring you self-defense weapons."

Zhang Yuping said with a smile while handing over the long daggers in his left and right hands.

"Thank you very much. There are no local wolves in Yanze. They must have come from the Altyn Mountains. Maybe they are hungry.

But looking at the night tonight, it is estimated that there will be a big sandstorm, and these wolves will not come through the sandstorm. "

"It's best as Professor Ye said, then I'll go back first."

After hearing Ye Zixuan's analysis, Zhang Yuping was still a little worried, and with a lingering solemnity on his face, he returned to the tent where he slept.

Seeing this, Ye Zixuan felt a little funny. There were no soldiers accompanying him to protect him. Isn't it because he and Xianyun were in the finale? !Let alone a wolf, even a tiger must lie down for me.

"Here you go." Ye Zixuan took the long dagger, zipped up the tent, and handed the dagger to the two female students.

"Thank you, Professor Ye." "Thank you, Professor Ye."

"Okay, sleep peacefully."

"..."

The two female students nodded when they heard this and put the daggers under their clothes that were used as temporary pillows. The worry on their immature faces also eased a lot.

Accompanied by the increasingly fierce cold wind and the "pop-pop" sound of gradually increasing sand grains hitting the tent, everyone fell asleep, even Ye Zixuan was no exception.

"Hey, wake up~"

"Huh? What's wrong?"

"I want to go to the convenience store, but I don't dare to go out alone..."

"Oh~ It's true, then I'll accompany you~"

"Hehe~ I knew you were the best~"

"Poor mouth~"

"..."

Ye Zixuan, who was asleep, still retained a trace of alertness. She vaguely heard the voices of two girls talking, and then the two of them left the tent. Ye Zixuan did not notice anything unusual and continued to sleep.

"I just came out to relieve myself, and I seemed to see two green eyes."

"What?! Wake everyone up! A wolf is coming!"

"..."

I don't know how much time passed, but Ye Zixuan was woken up by the noise outside the tent. Hearing such a conversation, Ye Zixuan opened her eyes in an instant because she felt that there was no one around, and the two girls had not returned yet.

Many people had gathered outside the tent, all of them guarding the surroundings with their weapons and flashlights constantly shining in all directions.

However, due to the level 6 or 7 sandstorm and the night, the visibility was extremely low, and the light beam was blurry when it was less than ten meters away.

"Senior Aunt!" "Professor Ye!"

"..."

"Chen Zhizhi and Wu Yuzhen haven't come back yet. I have to go find them. Xianyun, you stay to protect everyone!"
