The truth of the matter is that when the mudslide erupted, a river in the Qianhui Mountains happened to be blocked, and the rising torrent just happened to float away Kang Mingsong's tent.

After the flash flood subsided, there was no trace of him being washed away.

However, their tent drifted into another stream and flowed into the most complex terrain in Qianhui Mountain, the Misty.

The stream that their tent drifted into dived into the ground in a cave outside the crater and became an underground river, and then flowed out in the northeast direction of the crater, and after crossing the labyrinth, it disappeared again under the cliff and flowed out in the form of an underground river.

This labyrinth is not the largest among the many labyrinths in Qianhui Mountain, and can only be regarded as medium-sized. However, the terrain is the most magical, as it is surrounded by completely sealed craters, isolated from the rest of the world. If it weren't for the planes flying directly overhead, it would have been impossible to find out what was going on.

Moreover, the straight-line distance from the incident site is more than six kilometers, which is beyond the radius of the military helicopter search, so even if the garrison dispatched a helicopter search and rescue, they still did not find their existence.

Of course, neither Yuan Bingya, nor Kang Mingsong, nor many military search and rescue personnel knew about these situations.

………………

After listening to what Yuan Bingyan introduced in the past two days, Kang Mingsong finally understood why others didn't come to him and Yuan Bingyan.

In this small sealed basin with no roads to the outside world and no telephone signal, there is a real isolation.

Over the next two days, Mr. Cummingsong regained some mobility and was barely able to walk. This is due to the fact that Kang Mingsong is a native of the countryside, and his deceased second uncle is also a famous barefoot doctor in the village.

In this small basin, there are many herbs, and Kang Mingsong happens to know two of them, one is called salvia, and the other is dendrobium.

Salvia miltiorrhiza is a kind of traditional Chinese medicine that is widely distributed in China, and is born in the grass, ditch, roadside or forest side of the sunny hillside. It is distributed in most parts of the country. It has the effect of invigorating blood and removing blood stasis, relieving pain through menstruation, clearing the heart and removing troubles, cooling blood and eliminating carbuncles.

Dendrobium officinale is even more famous, is China's precious national secondary protection plant, the growth environment and climatic conditions are very demanding, it grows at an altitude of 500 ~ 1000 meters, relative humidity in 60% ~ 75%, forest transmittance in about 60%, growing season temperature 20 ~ 25 °C, winter temperature 9 ~ 12 °C, in the frost-free foggy, annual rainfall of 1100 ~ 1500 mm of evergreen broad-leaved forest and limestone.

Due to the extremely harsh requirements of wild Dendrobium officinale to natural ecological conditions and the extremely low natural reproduction rate, as early as the eighties of the last century, Dendrobium officinale was listed as a rare and endangered medicinal plant under key protection by the state.

Dendrobium officinale has many effects such as enhancing immune function, promoting digestion, protecting liver and gallbladder relieving, anti-rheumatism, lowering blood sugar and blood lipids, anti-tumor, protecting eyesight, nourishing skin, anti-aging, etc., and is called "giant panda in the pharmaceutical world" by the international medicinal plant community, and is called "life-saving fairy grass" by the folk.

With these two Chinese herbal medicines, Kang Mingsong's recovery is much faster.

………………

Kang Mingsong, who had regained his mobility, re-explored this small basin with Yuan Bingyan again, and touched the environment here.

Kang Mingsong, who has a certain understanding of Qianhui Mountain, knows that this should be one of the legendary "maze pots" of Qianhui Mountain, and it is a fully enclosed maze with a very special environment.

As for why they came here, Cummingsong also had some guesses, because apart from the stream that runs through the small basin, only the sky is connected to the outside world.

Naturally, they could not have flown in from the sky, so there was only one possibility of entering them along the stream from the underground river.

Nowadays, the only way to leave this place is through the underground river, apart from the sky.

It's just that, for now, neither approach is reliable. All around are cliffs hundreds of meters high, steep and impossible to climb, and they have no wings to fly out.

As for the streams that flow out of the small basin from the ground, it seems that it is also impossible for them to get out by this method, because both Yuan Bingyan and Kang Mingsong are very average in terms of water nature. In a coma, they were lucky enough to get in, but when they were awake, they could no longer swim out of the water.

God knows how long the underground river is at both ends, and what dangerous creatures exist in the underground river?

………………

After exploring around for five days, Kang Mingsong and Yuan Bingyan were completely desperate.

Although I know that the parents of both sides are very anxious now, after all, it has been seven or eight days since the accident, and there are no dead people or corpses, and it is estimated that the sky has already turned up outside.

However, if you can't find a way out, you can't find a way out, and everything is not transferred by the will of the two.

At the moment when the sun was setting over the mountains in the southeast, Kang Mingsong and Yuan Bingyan sat in the dimmed cave, looking at each other.

With his head in his hands, Cummingson lay on the floor of the cave. Beneath him, a layer of hay called monkey fur by the locals was fluttering, soft and comfortable.

In fact, this is also a kind of Chinese medicinal material, the scientific name is called Shenjin Cao, also known as Lion Grass, Shujin Cao, and a lot of aliases, such as Lion Grass, Oxtail Grass, Dashun Teng Vine, Da Shen Jin, Baibu Tendon, Water Shake Bamboo, Dragon Whisker Grass, Oxtail Tendon, Oxtail Stretching Tendon, Oxtail Section, Oxtail Roll, Water Ball Flower, Large-leaf Tendon Tendon, Wide Tendon Grass, Oxtail Fern, Tendon Ling, etc. It is a dried whole grass of the lycopodaceae plant. It is distributed in the south of the Qinling Mountains in China, and is mostly epiphytic on cliffs or between old trees with bryophytes.

This herb is very beneficial for treating rheumatism, and the villagers in the mountain township like to use its hay to make beds, not only to keep it soft and warm, but also to treat rheumatism.

After being stunned for a while, Kang Mingsong said faintly: "Bing Aya, this is simply a copy of the bottom of the ruthless valley in Jin Daxia's novel, it seems that we are going to be Yang Guo and Xiaolongnu here." ”

Yuan Bingya was originally quite depressed, but when she heard this, she sneered and said, "Because Mao is Yang Guo and Xiaolongnu, I have the beauty of Xiaolongnu, but are you as handsome as Yang Guo? Moreover, I'm much younger than you, right?"

Kang Mingsong said with a smile: "Where is Yang Guo handsome, black and black, I am much whiter than him." As for age, whether it is Lao Gu or Xiao Huang, they are better than Goddess Li and Liu Tianxian who play Xiaolongnu. ”
