This is a large oceanic lake, because of the influence of orogeny, more than a dozen high mountains are surrounded by a circle, forming a high mountain flat lake.

This large lake has a beautiful name called 'Fairy Lake', and according to legend, it is a beautiful legend that it was created by the mirror of the Nine Heavens Fairy dressing.

The endless surface of the lake is like a huge mirror, embedded in the mountains. The blue sky is reflected in it, making it difficult to tell where is the water and where is the sky?

A few goshawks hung high in the sky, looking like worms frozen in amber, motionless, and if it weren't for the occasional hawk cry or two, people would have thought that they were not living creatures. On the surface of the lake, a large flock of waterfowl flapped their wings, flew up and down, swooped into the lake to hunt, and the goshawks in the sky moved and still, complementing each other.

According to the altimeter, the expedition is now more than 2,400 meters above sea level, so it presents a very different landscape from the rainforest that passed through in the morning. In the Koaoyama area, the landscape changes wonderfully along the way from the foot of the mountain because of the drastic change in altitude.

This morning, the expedition team also wandered in the jungle of the Wangtian Tree, feeling the sultry heat and vigorous vitality of the tropical rainforest. After setting off at noon, the expedition team experienced subtropical evergreen broad-leaved forests, coniferous deciduous broad-leaved mixed forests, alpine meadows and other landscapes. In just half a day's journey, but only 10 kilometers away, the expedition team crossed from the tropics to the subtropical, temperate and subarctic zones, confirming the saying 'ten miles of different days'.

The expedition is now located on the shore of the high mountain flat lake, and a large alpine meadow is like a huge green carpet, spread flat on the plateau. On the meadows, colorful flowers bloom in the sun, gently swaying in the breeze.

On the opposite side of the lake are towering peaks of snow-capped peaks that shine in the golden sun.

After crossing the mountain beams, the members of the expedition team were stunned by the boundless beauty before them, and they stood motionless on the grass, greedily breathing in the fresh air, as if they wanted to take every sight to heart.

Great lakes, snow-capped mountains, grasslands, blue skies, white clouds,......, every scenery is so pure and immaculate, there is no sign of artificial carving at all. Such a beautiful scenery is like a clear spring, flowing gently in everyone's heart, so that everyone is suddenly immersed in a kind of inextricable touch.

After a long time, Liu Rui's consciousness woke up from his trance.

In the past, Liu Rui could only see this kind of picturesque beauty in some photographic works, but he did not expect that he would one day stand in front of this beautiful picture. Liu Rui felt that the entire expedition team was like an uninvited guest who broke into the landscape painting, and his movements suddenly became cautious, for fear of disturbing everything here.

The members of the expedition team who woke up from the shock, under the leadership of Wang Hua'an, found the location of the camp, prepared to set up camp, and went to the 'Eagle Sorrowful Stream' tomorrow morning to investigate the existence of the leper turtle.

"Fourth uncle, why don't you go directly to the 'Eagle Sorrow Stream' and camp here for one night?" Liu Rui, who was following Wang Hua'an to set up a tent, was a little puzzled, and now it was only four o'clock, and he was about to set up camp.

"It takes about an hour to walk from here to the 'Eagle Sorrow Stream', but there is no suitable camping site along the way, so for the sake of safety, it is better to stay here for one night and travel lightly tomorrow morning, which will save a lot of trouble." Faced with Liu Rui's question, Wang Huaan patiently explained.

Regarding the situation of the 'Eagle Sorrowful Stream', Wang Huaan only learned about it when he followed Zhang Huaizhong here for the first time. At the beginning, he also slowly learned a lot of jungle knowledge under Zhang Huaizhong's teaching, had an in-depth understanding of the surrounding terrain and environment, and grew into a senior forest hunter. Now that 20 years have passed, the object of his teaching has become Liu Rui again.

Perhaps, life is a cycle.

Unlike last night's campsite where we had to clear the weeds, camping in the alpine meadows today is relatively simple. Wang Huaan found a flat grass at the foot of the mountain with his back, and after checking it, he asked Qiu Rong to take a few graduate students to set up a tent, while he and Zhao Laosan took out some tools and walked to the lake.

Seeing that there was nothing to do with himself in the camp, Liu Rui simply took Xiao Hei and followed behind Wang Huaan, ready to see the situation of this mountain and big lake. Xiao Hei, who had been trapped in his net pocket all day today, was suddenly liberated, and he was having fun in the grass, clumsily chasing the birds that were foraging in the grass.

All of a sudden, there was a commotion in the meadow.

"Fourth uncle, why don't you camp on the beach by the lake? Wouldn't that be great? Liu Rui pointed to the flat beach by the lake, a little puzzled.

"Xiao Rui, you don't understand this!" Zhao Liang next to him turned out to be talking, and said: "The beasts on the mountain will go to the lake to drink water in the middle of the night, if you put the camp tent by the lake, it will be very dangerous!" ”

Under the guidance of the two old hunters, Liu Rui discovered that there were a lot of large and small footprints on the seemingly flat beach, as if someone was performing performance art on the beach.

The plum blossom-shaped footprints may have been left by leopards, the deep strings of footprints were those of wild boars, the shallow and scattered footprints may have been left by alpine hares, and there are some very vague footprints, most of which are the masterpieces of foxes and other animals,......。 After Wang Hua'an's explanation, Liu Rui found that in the depths of Xiaoqingshan, there are still so many wild animals, which is really unimaginable.

"What's this?" Looking at Liu Rui's shocked look, Wang Huaan said: "At the beginning, the master hunted the South China tiger near here, hundreds of catties, and several strong men carried it all the way down the mountain, but it was a sensation!" ”

Wang Huaan's master is Liu Rui's grandfather, and when it comes to the past, Wang Huaan is also immersed in it, and his face constantly appears to remember the glory of the past. For these hunters of the older generation, it is also a reincarnation to hunt wild animals desperately in the early years, but to become animal protectors when they are old.

"Fourth uncle, then do you think there will be tigers in Xiaoqingshan now?" When it comes to tigers, Liu Rui's eyes light up.

In his grandfather's bedroom, Liu Rui can often see the formidable tiger skin, and he once described in his heart, when it is alive, what kind of majesty should it be?

"It's hard to say now, we haven't seen a tiger in twenty or thirty years, who knows if there are any more?" Speaking of this, Wang Huaan was a little sad and said: "Maybe there will be sporadic existence in the depths of the verdant mountain, no one knows!" ”

Speaking of this, Liu Rui's gaze couldn't help but turn to a series of huge snowy peaks on the opposite side of the big lake.

Under the influence of orogeny, the verdant mountains suddenly rise in the middle of a hilly area, creating a relative drop of thousands of meters from the surrounding environment. It is precisely for this reason that in the summer of the Tropic of Cancer, Liu Rui can still see the snow. Due to its rugged terrain and low population density, this mountain range has not been the focus of attention. Moreover, these snow-capped peaks are only five or six thousand meters above sea level, and compared to the famous peaks of the Qinghai-Tibet Plateau, they are not the objects of great conquest by mountaineers, so it is not surprising that they are not famous.

The sunset set quietly at the end of the big lake, and the golden sunlight shone on the snow peak from the side, allowing Liu Rui to see the steepness and majesty of the snow peak more clearly. At this time, Liu Rui thought to himself, if he can climb to the top of the snow-capped mountain in the future, how hearty will it be?

Just when Liu Rui was in a daze, Wang Huaan and Zhao Laosan sprinkled some special bait into the lake, and when a fish appeared, the small fish net was cast, and a lot of fish were caught after a while. Liu Rui saw that the crucian carp and carp still knew about it, but he didn't know the fish with five elements of plate bones and sharp spines like armor.

"Fourth uncle, what kind of fish is this?" Liu Rui squatted down and picked up the strange fish on the beach, this fish can be at least five or six catties, and it is heavy in his hand.

"This is a sturgeon, which is rarely seen in Xiaojing Lake, and only occasionally encountered in Fairy Lake!" While disemboweling the fish in his hand, Wang Huaan said with a smile: "Today is considered our luck, and we will catch one as soon as we go down the net." ”

"This is the sturgeon?" Looking at this famous fish with some curiosity, Liu Rui's eyes were full of curiosity. He had only seen pictures of sturgeon in books before, but he had never really seen this rare fish called 'living fossils in the water'.

"Fourth uncle, this fairy lake is so high, how can there be fish life?" Liu Rui really didn't understand.

"Then I don't understand, anyway, there have always been a lot of fish in this fairy lake, you should ask Teacher Yu this question." Wang Huaan replied with a smile.

"Oh yes!" I slapped the door of my head, and then I woke up.

For many things in Xiaoqingshan, Wang Huaan and they are limited by knowledge, and many things are known but do not know why, and it is a bit difficult to get him to the bottom of it. For questions like the one just now, it's better to leave it to Yu Shanwei to give an answer after observation.

A few people quickly cleaned up the fish they had caught, and then filled the lake with two soft plastic bags before returning to the camp. At this time, Qiu Rong had already led the students to set up the campsite, picked up firewood, and began to prepare dinner.

Yu Shanwei, Han Zhengbao and Xu Wenchang sat on the meadow on the side, discussing the harvest along the way. For them, it was a bit unexpected that there were so many discoveries and surprises in a casual expedition! Perhaps, after returning home, the entire scientific expedition will change from a single project to a comprehensive investigation of the entire Xiaoqingshan area, and interpret the ecology, vegetation, species and development trend of Xiaoqingshan from a more comprehensive perspective.

Perhaps, this will be a great discovery that will amaze the world!
