Everyone discussed it for a while, and they were going to go down to see the situation of the shaft under the pond to see if they could find anything. After agreeing, Xiao Qingfeng asked the mute and the four of them to find three fixed points on it, and then put down the three climbing ropes at the same time.

After the four of them were dumb, Xiao Qingfeng and Jingxin took the lead in descending the rope, stepping on the smooth rock wall of the deep pool, and easily reached the wellhead at the bottom of the pool below. After reaching the bottom of the pool, the two found that the wellhead of the dark green square well below was still very slippery.

But it is obvious that there are several clear adult footprints on the edge of the wellhead of this square well, which proves that the rumors of the people a few days ago are indeed true. It seems that there were people here who had been here in advance, and they had also gone down to the bottom of the pool below to explore. I just didn't know what the results of their exploration were, so I put up the warning sign on the edge of it and left.

After the two made sure that the situation below was safe, they asked the doll to fasten the safety rope and slowly descend to their position with the SLR camera. After the doll arrived, the three of them began to use a strong flashlight to irradiate the shaft to observe, and took continuous rapid shots of the inside from multiple angles. Even a special tunnel probe was hung inside, and a series of key factors such as temperature and air quality in the depth of the shaft were carefully inspected and recorded.

After more than ten minutes of careful inspection, Xiao Qingfeng and the others had a general understanding of some of the conditions under the shaft. This seemingly bottomless shaft is almost completely vertically downward, with little change in inner diameter, and is roughly 278 meters deep. At the beginning of the six or seven meters, the shaft is all square and regular, and at the bottom of six or seven meters, it gradually becomes an irregular circular shape.

The entire shaft wall is an unusually slippery dark green rock wall, which is supposed to be made of roughly the same material as the rock wall of the deep pool above, except that the surface of the shaft is covered with some unknown mosses due to the perennial immersion in the past. The temperature inside the shaft is relatively high but constant, and the air quality is normal, so it seems that the air circulation below is relatively stable.

In addition, there is still a lot of water vapor in the depths of this shaft, if nothing else, there should still be water in the depths of the shaft, but the actual situation below can only be clarified when you actually go down inside.

After the three of them made relevant records, they returned to it for safety.

After coming up, the seven of them briefly discussed, and Xiao Qingfeng first said: "This deep pool is indeed very strange, the shaft below is not only unfathomable, but the wall of the shaft is full of unusually smooth rocks, even smoother than ordinary machine shafts. In addition, the whole shaft is relatively neat and straight, and at first glance it looks like it was dug by modern people with modern machinery. But after careful inspection, there is not the slightest trace of excavation, and the name of this 'Phoenix Ass Gate' has long appeared in some ancient notes, so it is more like a masterpiece of nature. Personally, I believe that the existence of this special deep pool casing well should be a peculiar geological phenomenon naturally formed during a certain crustal movement in ancient times. ”

"I can see from the probe shooting deep into it that there seems to be a mist surging underneath, as if something is stirring inside. However, upon closer inspection, no living creature was found. To be honest, my instincts tell me that there seems to be a flowing stream of water at the bottom of the shaft, and I seem to faintly hear the sound of running water, but it is extremely uncatchable. So, this is just a bold guess on my part, and there is no real basis for it, and I haven't mentioned it casually below. ”

"Underground Dark River", the doll suddenly shouted: "Don't you say I really forgot, just a few days ago, I listened to a man who accompanied me in the hospital and talked about it." It is said that a few years ago, the provincial geological department discovered a rich reserve of groundwater near us, and also speculated that there may be a number of active underground rivers in our area. He also said that we may have the largest underground water-rich area in the province, and we are preparing to conduct formal underground drilling here. I heard others say that this man seems to be a deputy section-level cadre of the Water Conservancy Bureau, and what he said should not be groundless. I'm going to have to go, we won't find some legendary underground river today, hehehehe......"

Mengshan Turtle said: "If you want to say so, maybe the depths of this shaft are really connected to the East China Sea through the underground dark river as the legend says." Didn't someone say many years ago that the Dulong Pond in Mount Tai is connected to the Dragon Palace of the East China Sea, but it has never dried up, so no one has really cracked all kinds of weird legends there. Now that I think about it, what kind of Dulong Pond is similar to our mysterious phoenix ass door today. It's all the same weird, and it's all the same deep pool and dark well, so maybe they really have something in common. It's just that our current place suddenly and unexpectedly dried up, which gave our buddies the honor to see its true face. If you want me to say, let's go down and find out, and if we get it, our buddies can sneak to the East China Sea Dragon Palace from here to have fun, hehehe......"

The dumb man said: "When the doll said this, I remembered some strange things that some craftsmen who quarried here in the early years said. Many of them have said that when they bathed in this deep pool in the early years, they did not dare to dive deep and pierce the fierce son. It is said that when you dive to a depth of seven or eight meters in the pool, you will sometimes feel a strange downward whirling force, as if you want to suck the diver down suddenly. However, on the surface of the pool, it has been as calm as ever for many years, and there are no major fluctuations in the slightest. Now that I think about it, it is possible that there is really a flowing underground river under the shaft at the bottom of this pool, which is why there is this strange siphon phenomenon that they say. ”

The little Taoist priest said: "I agree with Ah Turtle's statement, or let's go down today to find out what the doll said about the underground river." ”

Laughing Maitreya said: "Forget it, according to me, forget it." Even if the shaft under the deep pool is really connected to some underground river, with our current equipment and experience, I feel that we really don't have the ability to do this. I think let's follow the original plan and study the weird and mysterious 'Lost Soul Valley' in this place. As for the mysteries and oddities of the shaft below the bottom of this pool, let's just wait and see the news. Now that the geological department above has intervened, it will definitely come up with a result. Just now, when Hou Ye was down there, I looked around again, in addition to the warning signs on the side of the pool, the same warning signs were also found in the east and north directions, and it seems that this place has been paid attention to by the relevant departments. ”

Mengshan Turtle muttered in a low voice: "Forget it, I think it's better to call Brother Wolf back, as soon as Brother Wolf is not at home, we will become timid." What's the big deal, isn't it just a small underground river? In our hometown, the famous underground canyon was discovered and caused by a group of outdoor adventure buddies in the early years, and it is said that those buddies have really made a lot of money because of it. I don't dare to say anything else, as far as the ability of their group of people is concerned, they are definitely not as good as our Nine Immortals. Even if we only have the Seven Immortals now, then we can easily throw them off ten or eight streets, baby girl, right?"

Before the doll could answer, she was glared at by Xiao Qingfeng and suffocated back. I saw Xiao Qingfeng kick a solid kick on the ass of Mengshan Turtle, and scolded with a smile: "You stinky turtle who stirs trouble all day long, before I can speak, you will put a 'fearful' hat on me first, believe it or not, I will kick you down now, and let you go to the Dragon Palace of the East China Sea to be your turtle prime minister, hahaha......"

After everyone burst into laughter, Xiao Qingfeng continued to smile and said, "But don't worry, when we find out the 'Lost Soul Valley' near here first, I will definitely contact Brother Wolf and ask him to come back to coordinate the arrangements." After he gets it done, let's really go down and see what the mystery is down here. Okay, now let's clean up briefly, let's spread out and figure out the first thing first. ”

Around the deep pool, there are three distinct main valleys: one to the west, about two kilometers, and the final end leads directly to a north-south country road, one to the east, about 800 meters, and the last end is a low extension of the Yellow Mountain, and one to the north, about 1,500 meters, and the last end is a mountain orchard that has been cleared by the villagers.

Of the three valleys, the one to the west is not only the most varied in length, but also the most complicated, almost overgrown with thorny bushes and some nasty wild weeds. The other two seem to be much better, but they really have nothing to do with the legendary and unpredictable "Valley of Lost Souls".

After analyzing the general situation of the surrounding area, the seven of them still had a serious discussion, and then carried out a field survey of the surrounding valley in a planned manner.

Xiao Qingfeng and Xiao Daoist used their academic knowledge to conduct a series of reasoning calculations within a range of dozens of meters around the deep pool. Jing Xin and the doll still use binoculars and SLR cameras to carefully examine and photograph the three main valleys that extend outward from all sides of the deep pool, and correspond to the data and photos on the top of the mountain.

The remaining three people, the mute and the laughing Maitreya and the Mengshan turtle, each traveled along the three main valleys, searching, and made a conspicuous mark every ten meters as required.

The search of the three of them into the valley during the day, especially the marking operation, was completely prepared for the real operation at night.

Considering the actual situation of the three valleys, the dumb man chose the most difficult one to the west, and the laughing Maitreya chose the one to the north, and the two left the one to the east that he was very happy to do. According to the agreement, the three of them had to complete the marking and get out of the valley within an hour, and then quickly return to the original place according to the original route.

The mute trio simply cleaned up, and each confidently began to search and mark their own routes. At the same time, Xiao Qingfeng and the others also started their respective work, and they were busy in a tense and orderly manner.

An hour passed quickly, but none of the mute trio had returned as planned. For safety reasons, Xiao Qingfeng began to ask Jing Xin to order them to return to the team as soon as possible. After receiving their answers, more than twenty minutes passed, and the three of them returned to the edge of the deep pool one after another. At this time, I saw that all three of them lost the elation they had when they set off, and they were all depressed and spiritless.

Mengshan Turtle took the lead in scolding and muttering: "Damn, what is the matter, this short eight or nine hundred meters ordinary broken valley, I have taken so long to come and go." It's fucking surprising that four or five times in the middle of the day, I lost the mark I had just marked and spun around in it. Fortunately, my concentration was okay, and finally I closed my eyes and groped my way forward, and then walked out. Otherwise, it's really a fucking adult today, I'll go!"

Xiao Maitreya also said angrily: "My situation is not much better, I feel that I have played back and forth in at least a dozen times inside, just like the kind of ghost hitting the wall as rumored." It looked like it was the right path, but as I walked, I turned back and turned my head bigger. I still haven't figured out why this is happening, but in the end, I relied on my excellent hearing and followed the sound of your chat, and I broke out. ”
