As night fell, a Buick business car stopped at the entrance of a small village more than 40 kilometers southwest of the city, and eight people walked down from it, led by Li Er's grandmother. Pen "Fun" Pavilion www.biquge.info

This is the most remote corner of Fangshan District, about 10 kilometers away from Fangshan, surrounded by mountains, inhabited by a small village of more than 300 people.

Although the mountains are also tall and rugged, rich in vegetation and unique scenery, for some reason it has not been developed by the Municipal Tourism Bureau. Not to mention at night, even on weekdays during the day, it is quiet, and there are few tourists, but it has become a holy place for adventure travelers. However, the winter snow has not yet melted, and it is not common for travelers. If it weren't for the second grandmother's guidance, I really wouldn't dare to imagine that the real entrance to the locked dragon well was here.

Since this time it is a path, the place is remote, and there are not many expensive people, except for the second uncle and the second sister Sun, the rest of the six people are all elite apprentices under the second grandmother, and the magic cultivation is not under the second uncle.

Speaking from the bottom of my heart, I am grateful to the second grandmother. After all, at such an age, no matter how high my cultivation is, my physical strength is far inferior to that of young adults, I really don't know what to say if I can run around so much for me.

With a nearly twenty-kilometre river flowing in front of us, and the village was in its downstream stage, we rented a rubber boat and sailed upstream.

Speechless all the way, Second Grandma Li watched the scenery on both sides of the strait closely, which made us nervous.

As the rubber boat drove in, the sky became darker and darker, and there were black holes all around, and I couldn't see anything clearly, but I only knew that the terrain was gradually rising, and it seemed to be at the foot of Fangshan Mountain Peak somewhere upstream.

The river is getting wider and wider, and the terrain is getting more and more flat, as if you have come to a vast lake.

After a while, Second Grandma Li shouted: "Slow down, Xiao Yangzi, shine the headlight in the direction of two o'clock."

The second uncle at the helm heard the order, and the lamppost shot in that direction, revealing a black hole.

The entrance to the cave is about six meters high, in the shape of an equilateral triangle, and although the wind and rain have been very eroded, some traces of artificial excavation can be seen.

Second Grandma Li took a closer look at it, nodded and said, "This is it, drive the boat in." ”

Looking in from the entrance of the cave, there was nothing to see inside, and the second uncle was worried: "Won't you hit anything when you drive in?" ”

Second Grandma Li said: "You stupid Yangzi, if you don't drive the boat in, will you swim in all the way?" Don't worry, the second aunt has been there once in decades. This hole was originally an outlet, and I know the path inside very well, so you just have to go in. Be slower, though, as some of the rivers are narrow, so don't bump into them. ”

Hearing this, the second uncle no longer hesitated, and slowly sailed the boat into the cave.

Everyone turned on the overhead light on their helmets, but they saw that the holes around them were slightly narrow, and they might hit them if they were not careful.

After moving forward for more than 20 meters, I turned a corner, and suddenly a light stood out in front of me.

The moon was round tonight, and the bright moonlight poured down on the mouth of the cave, reflecting the shape of a small lake.

I didn't expect this hole to be so short, and I came to the exit less than forty meters, and I was about to ask a question, but I saw Grandma Li Er excitedly said: "It's here!" Lo and behold, that's the sunroof. ”

"Second aunt, what is a skylight?"

Grandma Li said: "The skylight is a space where the underground river is exposed to the surface. ”

The opening is much smaller than the previous entrance, and when the boat reaches there, we reach out and touch the stalactites on the top.

The huge skylight in front of you is surrounded by cliffs, and the lake under the skylight covers an area of thousands of square meters. I couldn't help but wonder if the imaginary skylight was supposed to be a window on the cliff face, and then the moonlight came through that window, how could it be like this?

Afterwards, I consulted the relevant information, only to know that this Fangshan area belongs to karst landform features, and the skylight was originally the same as I described, a small top window, but after many collapses in tens of thousands of years, it gradually formed the appearance in front of me. The formation process of skylights and sinkholes is generally similar, but academically it is determined that those with a window diameter of less than 100 meters are called skylights, and those with a diameter of more than 100 meters are called sinkholes. The lake in front of me has gone beyond the skylight and has become a sinkhole.

On the other side of the lake is a cliff, and there is an equilateral triangular hole below, and the second grandmother Li ordered the second uncle to drive the boat into it.

It was a cold winter, the cold wind outside the cave was cold, as soon as you entered the cave, a warm current suddenly rose, the temperature in the cave seemed to rise several degrees, and the surrounding area was covered with upside-down stalactites.

I thought this was the destination, but after more than 50 meters, a sinkhole lake with a diameter of 100 meters appeared in front of me.

There is no hole resembling an equilateral triangle under the cliff on the opposite side of the lake, but a semi-circular opening. Second Grandma Li pointed to the entrance of the cave and said, "It's here." ”

This cave is not like the previous two caves, there is a river running through it, there is no trace of water in it, the ground is cracked, the boat cannot approach, everyone has to abandon the boat and walk. However, when I stepped on the ground, I found that the ground was very muddy, and it was clear that the water content in the cave was high, but why didn't it show it in the form of a river?

Everyone walked on the ground with one foot deep and one foot shallow, and after a short time, there was the sound of gurgling water in front of them, and under the illumination of the overhead light, a trickle appeared in front of them. The creek is narrow, but the current is rapid, and apparently there is an outlet deep in the cave.

As he walked, the second uncle suddenly said, "Second aunt, is this the rumored Lock Dragon Cave?" ”

Second Grandma Li said, "Have you been here?" ”

The second uncle shook his head and said, "It's the first time I've come back here, but I've heard a long time ago that there is a sinkhole group in Fangshan District, and the other sinkhole leads to the underground dark river, from where it leads to the Bohai Sea." However, there have been many people who died in the pit of heaven, and it is said that there are giant beasts infested, could it be the dragon under the dragon well? ”

I shook my head and said, "What you said are all folk rumors spread by falsehood, and the truth may not be so.

Li Er's grandmother said: "The so-called flowing water does not rot and does not beetle, even if there are no aquatic creatures such as small fish and shrimp in the river here, there must be some aquatic plants, you look at this underground undercurrent, you can neither see fish and shrimp nor aquatic plants, it is such a calm lake, but the air is filled with the smell of corruption, but the water quality is so clear, don't you feel different?" ”

Everyone nodded when they heard this, and these words of Second Grandma Li pointed out the abnormalities of the sinkhole lake here.

At this moment, a disciple of the Hu Sect named Zhou Wang went to the side to relieve himself, and after a while, he suddenly let out a low cry.

Everyone hurriedly ran over, only to see that the zipper of his trouser door was not properly opened, revealing that piece of thing. In addition to Grandma Li's second grandmother, everyone present said that Second Sister Sun was a woman. The second grandmother is old, but it's nothing, but the second sister Sun turned her head red, hurriedly turned her head, and scolded: "Die Wangzi, play hooligan!" ”

"Dead ...... Dead person...... Bones ......" Zhou Wang knew that he was out of shape, and hurriedly pulled the zipper, pointing to the side of the cave wall with a panicked face.

Everyone looked at it and couldn't help but gasp. (To be continued.) )
