Yellow River Craftsman

Chapter 72
On the gravel fault not far from us, dense black spots suddenly appeared, and those black spots were moving towards us at an extremely fast speed.After they entered the range illuminated by the fire, we suddenly discovered that those black spots were actually a group of lizards with patterns on their backs!

There were hundreds of lizards, the smallest one was only an inch long, and the largest one was one meter long. They crawled quickly in the sand, constantly ejecting their scarlet snake-like tongues, making a hissing sound.

My heart sank unsteadily into the black abyss, this is really a wave of ups and downs!

However, Lao Luo exclaimed in surprise: "God, open your eyes! We are saved! We are saved!"

I looked at Lao Luo blankly, and Lao Luo pointed to the group of lizards that were crawling fast, his voice trembling with excitement: "This is sand lizard, they are the natural enemies of fire ants, this time we are saved!"

I was startled suddenly, what?Are sand lizards natural enemies of fire ants?So, these sand lizards are not coming for us, but for these fire ants?
"Everything in the world generates and restrains each other. Where there are fire ants, there are sand lizards! Although these fire ants are fierce, they are the most delicious food in the eyes of sand lizards!"

Lao Luo didn't lie to us. These sand lizards are indeed the natural enemies of fire ants. With sand lizards joining the battle group, the situation on the field suddenly turned around. Under the siege and interception, they were quickly wiped out by large groups of people.

Those sand lizards are very good at catching fire ants. They crawl very fast and move very sensitively. After determining the target, their long tongues shoot out like lightning, wrapping a fire ant in a swish.Before the fire ant could react, its powerful tongue had already sent the fire ant into its mouth.

All things in the world are indeed mutual generation and mutual restraint. Although the fire ant is very fierce and even its blood is very harmful, the sand lizard is not afraid of it and can swallow it in its stomach.These fire ants are scary things to us, but to the sand lizards, they are a delicious feast. They eat with relish, and quickly wiped out the fire ant army, leaving no one left.

After having a delicious meal, these sand lizards quickly disappeared into the vast desert, just as swiftly and stealthily as they appeared.

The sky in the distance has already turned pale, and the sky is getting a bit bright. Unexpectedly, we fought fiercely with the fire ant army in the middle of the night.

The flames gradually extinguished, and countless charred fire ant corpses appeared, and there were toe prints left by sand lizards crawling on the sand. Recalling what happened just now is like a nightmare.

When the crisis was lifted, our tense heartstrings also relaxed, and we couldn't help but let out a long breath.If it weren't for the timely appearance of these sand lizards, there might be more than a dozen white human skeletons left on the sandy ground at this moment.

Facing the western sky, Lao Luo bowed reverently: "Thank you for God's blessing!"

We also imitated the appearance of Lao Luo, and bowed to the western sky: "Thank you for your blessing! Thank you for your blessing!"

Looking at the ray of dawn that pierced through the sea of ​​clouds, my heart was full of hope again. As the saying goes, "If you survive a catastrophe, you must have a future blessing." I believe that we will be able to overcome the difficulties this time and remove the poison in our bodies.

The hot gravel is under our feet, and the hot sun is above our heads. We are like withered leaves, lying listlessly on the back of the camel. With the bumps and bumps of the camel, it seems that the moisture in the body has been dried. After walking for half a day, we have to dry out the barbecue.

Just when we were drowsy, Gan Hongxin suddenly shouted excitedly: "Look ahead! What a big oasis!"

About a kilometer ahead of us, there is a beautiful desert oasis.Over the past two days, all that caught our eyes was the overwhelming yellow. Suddenly seeing such a verdant green, we felt refreshed physically and mentally, and even our eyes did not feel the burning pain just now.

Encountering an oasis in the desert is like finding gold in a mine, it is a very exciting thing.We can't wait to pat the camel and trot all the way towards the oasis.Covered in dust, I just want to jump into the lake and take a good bath.

As the distance continues to shorten, the appearance of the oasis gradually appears in front of our eyes.The water and grass are overgrown, the trees are shady, and there is a clear and transparent lake in the middle. The sun is shining on the lake, as if a pearl from the sky fell in the desert and melted into this oasis.

Lao Luo told us that the ice and snow on the mountains will melt in summer and flow down the slopes to form rivers.When the river flows through the desert, it seeps into the sand and becomes groundwater.After this groundwater flows along the impermeable rock formations to the low-lying areas of the desert, it gushes out of the ground.

In addition, rainwater from far away seeps into the ground and can also flow into the low-lying areas of the desert together with groundwater.Or due to the change of the earth's crust, the impermeable rock layer is broken, so that the groundwater flows along the crack to the low-lying desert area and rushes out of the ground.With water in this low-lying area, various organisms came into being, developed, and multiplied, so that an oasis in the desert was formed.

The further we walked, the more we felt that something was wrong. The oasis seemed to be swallowed up by the sea of ​​sand bit by bit.When we got close, the oasis had completely disappeared, only the hot sand waves were left, as if everything we saw just now was just an illusory picture.

I rubbed my eyes in disbelief, and turned my head to look around, but there was no sign of an oasis?
What about the oasis?
Where did Oasis go?
But in such a short period of time, is such a large oasis covered by the sea of ​​sand?

"Strange! Strange! Where did this oasis go? Why did it disappear?" Everyone also shouted.

Wang Dongyu jumped off his hunchback, took out the shark blade and dug in the sand for a long time, but nothing but gravel was found, and he didn't even see a drop of water.

"Don't look for it, there is no oasis here!" Lao Luo said.

"Impossible!" Wang Dongyu raised his head: "Obviously we all saw the oasis just now, did we all have hallucinations?"

Lao Luo sighed: "We have all been played by nature. What we saw just now is not a real oasis, but a mirage in the desert. People in the desert are usually called Sand Sea Ghost Land!"

We suddenly realized that this is the legendary mirage!

Gu Meidi sniffed: "In places such as calm seas, rivers, lakes, snow fields, deserts or Gobi, occasionally there will be tall buildings, city outlines, trees and other illusions in the air or underground, which are called mirages. Mirages are actually An optical illusion, which is a virtual image formed by the refraction of light reflected by objects on the earth through the atmosphere. The air itself is not a uniform medium. In general, its density decreases with the increase of altitude. The higher the altitude , the smaller the density. When light passes through air layers of different heights, it will cause some refraction.

The mirages that occur in the desert, the so-called sand sea ghostland, are actually the refraction of sunlight when it encounters air of different densities.In the desert, the sand is baked by the sun during the day, and the temperature on the surface of the sand layer rises rapidly.Due to the poor heat transfer performance of the air, when there is no wind, the vertical air temperature difference over the desert is very significant, the bottom is hot and the top is cold, the upper air density is high, and the lower air density is low.When the sunlight enters the low-density air layer from the high-density air layer, the speed of light changes, and through the refraction of light, the oasis in the distance is presented in front of people's eyes!

So, in fact, there is such an oasis in the desert, but this oasis is not here!It may be tens of kilometers away, or it may be hundreds of kilometers away! "

Gu Meidi is worthy of being an encyclopedia. This detailed explanation made everyone look at her with admiration, and some even applauded her.

Wang Dongyu jokingly said: "Little beauty, can't you tell, she's so knowledgeable!"

We didn't find the oasis, and the excitement just now was gone. We lay down on the hunchback again, squinting our eyes and taking a nap.

Sleeping in a daze until sunset, the fiery red sun seemed to release all the energy accumulated throughout the day at this moment, and the sky and the ground were filled with crimson colors.The breeze blew past, and the sand sea was churning layer by layer, like tumbling blood-colored waves, stretching all the way to the horizon.

"Oasis! There is an oasis ahead!" Gan Hongxin shouted excitedly again.

On the vast sandy land hundreds of meters away, there was indeed a lush oasis.

Wang Dongyu gave Gan Hongxin a blank look: "You idiot, didn't the little beauty explain to us before that it is a mirage, an illusion formed by the refraction of light!"

Gan Hongxin muttered, "Fart! Why do I look like a real oasis?"

Wang Dongyu said disdainfully: "If it's really an oasis, I'll take my head off and use it as a chamber pot for you!"

Gan Hongxin rolled his nostrils and said not to be outdone, "Hmph! Just wait and drink my night urine!"

A few minutes later, we came to a place less than 30 meters away from the oasis. Surprisingly, this time, the oasis did not disappear like a picture scroll, it still stood intact in the desert.

Lao Luo jumped off his hunchback first, and said happily: "This is not a sand sea ghost land, this is a real oasis! This is a real oasis!"

A real oasis? !

great!
That's great!
The crowd raised their arms and cheered, jumping off their hunchbacks excitedly. Even if they picked up a gold bar in the desert, they probably wouldn't be so excited.

Gan Hongxin looked at Wang Dongyu quite complacently, and with a strange tone, smiled sullenly: "Tonight, your head is mine!"

Gan Hongxin's words sounded like lines from a horror movie, coupled with his wretched and ferocious face, it made people feel chills.Those who didn't know thought he had the habit of collecting human heads.

Wang Dongyu's face turned green with anger, and after holding it in for a long time, he actually choked out a sentence: "Anyway, I belong to you..."

Wow!
We all vomited. Wang Dongyu's words were not aversion to cold, but nausea, which made us vomit all the acid in our stomachs.

Song Mingqiu muttered: "You two can't be good gay friends, can you?"
