The ghost brewed for a while, and poured a soak of urine on the ground, if the ghost hit the wall, it would immediately break the wall and return to the real environment. Regardless of whether it exists or not, try it.

After peeing, Oniku looked around, nothing had changed, and the trees on both sides were still there. Isn't it a ghost hitting the wall, and the number of trees here is circle by circle?

Oni Jiu looked at the tall trees in front of him and was a little stunned. This layer, I don't know how much, if there is nothing in it, it is not the place where my uncle goes, I have climbed too many layers, and the physical exertion is too great, will I not be able to get out.

Just as the ghost hesitated for a long time, he faintly heard the sound of a stone knocking, much like the sound of his uncle hitting the rock with a hammer before. Even if Onijiu was alert, his mind began to feel a little drowsy when he listened. Realizing that he was about to be hypnotized by the sound, Oniku immediately began to move his arms and kick his legs at the same time, but the sound penetrated his ears at a greater frequency. Oniku tried to cover his ears with his hands, but to no avail, and his voice became a vibration entirely, and his entire body was catering to this vibration.

Seeing that it was about to be completely controlled, Onijiu suddenly remembered the breathing method taught by the Mushi Taoist. So with a weak consciousness barely controlled the body to sit down, sink into the dantian in one breath, rotate 7 times clockwise in the lower abdomen, and then 7 times counterclockwise, and then go down along the lower abdomen, through the perineum, Guan Yuan, Fengfu, Baihui, down to Tianmu, into the upper jaw gingival intercourse, stay for a few seconds, and then go down to the Chengzhi acupoint, Tiantu, Jizhong, Guan Yuan. Rotate again clockwise in the lower abdomen, then go up again, exhaling through the nose.

After this cycle, Onijiu's consciousness gradually recovered. That's when I have the energy to find the source of the sound.

The sound of "click" came from the back of the inner tree, and Onijiu used a flashlight to shine inward at the crack in the trunk of the tree less than a foot, and the strong light of the LED illuminated the inside very brightly, and Ogiyasu pasted his face on it, there was no imaginary tree wall, it turned out to be a hillside, and the hillside was covered with stones, large and small, chaotic.

The ghost was excited for a while, it turned out that there were only a few layers of this tree wall! What else did you know about?

Climbing up the trunk of the tree smoothly, Onehisa found that the last layer of branches grew particularly luxuriantly, and they all stretched diagonally inward, as if attracted by the energy of the sun inside.

Descending to the ground, Onijiu shines a flashlight on the hill, which is not high, that is, a hillock more than 10 meters high, except for stones, there is nothing special.

Onijiu suddenly realized, why is there no knocking sound just now? There was a dead silence inside, no wind at all, and no sound of animals, birds, or insects. Although it is as quiet as when it first comes into contact with the outer layer, the silence inside gives people a more and more blank feeling, making people not even want to think.

There must be something wrong with this, Onijiu vigilantly raised his mind, guiding the breath to flow in his body non-stop, and at the same time walked towards the hill. At the foot of the hill, Onihisa took a flashlight and shone it on the stone at close range, and found that the stone under the flashlight was a little strange, and it turned out to be an ellipsoid. Shine a flashlight on other places, and every stone is shaped like this.

Oniku walked around the hill and found nothing suspicious except for the oval stone. The largest stone in it is only 50 centimeters, there are no weeds and plants, and the whole hill is clear under the flashlight, and there is no place to hide people.

Ghost Jiu is a little lost, it seems that his uncle didn't come here at all, and he was busy in vain. But after thinking about it, how to explain the knocking sound that just appeared? The sound is too similar to my uncle's beating, and the effect is similar, didn't I notice it?

There is nothing else on this mountain, only stones, is there something strange about stones. Onijiu shone the stones with a flashlight again, carefully and carefully, but found nothing to show for it. Onijiu suddenly remembered what his uncle said: What are we doing? Yes, we look at Feng Shui. Thinking of this, Onijiu suddenly realized a problem, and hurriedly picked up the flashlight and went to shine on those stones again, it was really like this!

It turns out that the stone where the ghost has been illuminated for a long time is different, the light is projected, and the yin and yang character pattern is just formed when the head is turned sideways, and the hexagram in the gossip is hung with a long and two short and a long, which is called the void in the middle. Onijiu is almost going to clap his hands, if this is in the daytime, anyone wants to see the pattern of gossip, because the stone is a hexagram reflected by the projection generated by the oblique light from the bottom of the slope, and the most amazing thing is that you can't see it at all, and you can't see it at all when you look at it, and you can only see it when you tilt your head just now.

Onijiu saw the mystery and began to go around the hill to observe other stones, thinking that he would see the other seven hexagram statues of Qiandui Zhenxun Kang Genkun, but what he saw were all hexagram statues, and there were more than 20 of them.

What do so many hexagram images imply? Where did that banging sound come from? The ghost pondered for a while, but he couldn't figure it out.

Simply, the ghost found a flat place to sit down, and his hand inadvertently touched the soil underground, hey! No, my location is right under the big pine tree, so I don't feel that there are too many pine needles, it's really strange.

Pine trees, especially this tall larch, drop many pine needles every year, and a thick layer of pine needles accumulates under the tree. The fact that this pine tree is not so deciduous is absolutely unreasonable. Did the leaves fall or were they taken away?

Thinking of this, Oni Jiu got up and kicked the trunk twice hard, and sporadic pine needles fell down. It can be determined that the pine needles fell normally, and the only possibility is that someone took them. But who in this mountain would turn over a few layers of tree rows and come here just to get some pine needles. Although pine needles have medicinal properties and can also be made into pine tea, there are pine forests in the Mongolian mountains, and no one will go to such great lengths to get them here. There's only one possibility, and the person who got the pine needles is here.

For his own analysis, Ghost Jiu thinks it's reasonable, so you have to look for it here, you must have not looked carefully.

Just as Oni was thinking alone, the rhythmic tapping sound of "click" sounded again. The voice is very subtle, but because of the method of listening to sound and observing the appearance taught by his uncle, Onihisa's hearing is more sensitive than that of ordinary people.

Carrying his breath, Onihisa followed the sound to the halfway point of the hill and put his ear to the ground, and the sound turned out to be from under here. But look at the feet are all stones, there is no entrance at all. Onijiu looked around with the light of a flashlight, and looked around the neighborhood, but still found nothing.

Just when the ghost was depressed for a long time, he suddenly remembered the experience of discovering the 'Soul Locking Worm Bowl' when he was a child, could this entrance also be on which tree? Looking at the big pine trees around, there are really dozens of quite stout ones, and the scene is at least a few hundred years old.

However, even if the entrance to the cave is in these trees, Onehisa's current physical strength cannot support it to climb each one to find it. After thinking about it, I still think that it is not realistic to find this way.

The ghost sat down on a stone in frustration for a long time, looked up at the sky, and the moon finally came out of the clouds and sprinkled coldly on the trees and stones. By the moonlight, Oni Jiu looked around the surroundings again, and the scattered stones, like people squatting there, looked at themselves in a daze. Separation of the hexagram, what does it mean, leaving the void, the hexagram of the separation appeared in front of the ghost for a long time, and the broken line in the middle is just like a mouth, by the way, can the entrance be in the middle part of the stone that makes up the separation hexagram! Thinking of this, Onijiu was a little excited.

Looking for these dozens of hexagrams is more realistic than climbing a tree, it doesn't take much physical strength, just do it, and the ghost began to look for it in the middle part of the stone of the hexagram statue.

Just when Onijiu found the eighth hexagram stone, Ogyu found a piece of lower stone in the middle of the two stones, with a particularly smooth surface, like a stone chair in a park that has been worn by people for a long time. The ghost squatted down for a long time and began to ponder, but he didn't see the reason when he looked left and right. So tentatively reached out to push, although the stone was not big, but it looked more than 100 pounds, and pushed, but there was no reaction.

Onijiu had enough strength and began to move upwards, when he heard a rumbling sound next to him, and a hole appeared at his feet. Onihisa shines a flashlight downward, and a staircase leads to the bottom of the cave, and the flashlight shines on a wall below.

Onihisa tentatively walked down, and when he reached the ninth step, the hole above shook again, and it closed automatically. Ghost Jiu was shocked, but don't trap yourself inside, hurriedly turned around and returned to the entrance of the cave, and after looking for a long time, he couldn't find the secret door to open and close. The heart is horizontal, whatever, since he has been trapped, why not spread it out, there may be other ways out.

After going down for more than 10 meters, I came to the wall where the flashlight was shining just now, and it turned out that it was not the end, but the passage made a 90-degree turn, and then turned to the left. Continuing downhill, about 200 meters downhill, a stone gate appeared in front of it. Onihisa pressed the knocker and pushed it in, and the door opened smoothly.

The scene in front of him shocked Onihisa a little: it was about 30 tsubo inside, with a stone mill in the middle and some yellowed pine needles piled up on the side. It turns out that someone is really transporting pine needles! When Onijiu came to the mill, he found that there was still ground pine powder on the grinding plate, and the stone roller around the central axis weighed more than 400 catties. This stone roller does not have the pushing handle and rope sleeve equipment that normal stone rollers have, and only one mandrel is inserted into the column in the middle of the grinding disc. Oni Jiu stepped forward, the flashlight shone on the column, and the flashlight light was reflected back a little, and then looked closely, and the middle column turned out to be copper.

Oni Jiu jumped on the grinding disc to study the copper pillar, and suddenly the stone roller on the grinding disc moved slightly, and Oni Jiu thought that his eyes were wrong, but then, the stone roller really rolled towards him slowly. Oni Jiu jumped down from it, and looked back at the stone roll, which was rolling smoothly with the center of the copper pillar as the center, pressing against the pine powder, exuding the fragrance of pine resin.

At the same time, the cave gradually lit up, and Onijiu looked at the light source and found a large incandescent lamp hanging on the top of the cave. There is still an electric light in the cave, where does the electricity come from?

Seeing the electric light, the ghost was calmer for a long time, and there was an electric light to prove that there were no ghosts, which proved the existence of people. People are not unknown to Onijiu, and they don't bring much fear.

It is a common state of mind that people are only more afraid of the unknown.

As the clock ticked by, there was no movement in the cave except for the rolling sound of the stone mill.

Onijiu moved to the edge of the stone mill again, turned around, and didn't find anything like a motor, so what did the power come from? What is pine needle powder on stone mill used for? Ghost Jiu is sure that this is definitely not a simple pine powder processing point, to process pine powder, you can build a workshop outside the mountain, the price of buying pine needles in the mountainous area will be very low, there is no need to go here to get a processing point, the transportation is inconvenient, and the output is limited. There must be some other use, but what can pine powder be used for, come here for seclusion and cultivation, and you won't need so much to make tea!

The ghost couldn't figure it out for a long time, so he simply looked around. When I went around to the innermost part of the cave, I found a small wooden door in the corner, and when I opened the wooden door carefully, I faintly heard the sound of water flowing, and a stone path appeared in front of me, with a great downward slope, an angle of nearly 70 degrees, and the cave was pitch black. Oni Jiu turned on his flashlight and cautiously descended.

The process is quite slow due to the steep slope. After about 20 minutes of traveling, the sound of water below became louder as the downward progression progressed. Could it be that there is an underground river down there? No, the underground river can't be so shallow above the surface. After traveling for more than 20 minutes, Onijiu finally went down to the bottom.

The space below is very large, the size of a football field, and there are also incandescent lights hanging on the roof of the cave. A river more than 5 meters wide is flowing forward with waves, and there is really an underground river!

Onijiu walked up along the river, walked a distance of nearly 20 meters, a big wheel appeared on the river, with the flow of the river, the big wheel was also rotating, on the side of the big copper wheel there was a smaller copper wheel, the small wheel had a conveyor belt, the other end of the conveyor belt was set on a standing copper pillar, the copper pillar was driven by the power of the conveyor belt, turning in one direction.

Ghost Jiu suddenly realized, isn't this a power system, the stone mill above must be started by this power, and there must be a generator in the cave that also uses the rotating energy of this copper pillar to generate electricity. Did you rescue it? q
