"You go to the southwest side, there's a stone path that leads underground." After a fierce psychological battle with Cheng Yifan, the ancestor said.

The southwest side is the end of the river, and Cheng Yifan flashlights and looks around at the end.

"What are you looking for?" Zhao Yawen looked at Cheng Yifan puzzled.

"Oh, I think there might be an exit here." Cheng Yifan continued to look down.

"The hole in the river is too small for people to pass, and I have already investigated it just now." Zhao Yawen said while patting the stone wall.

"Yifan, come and see, there seems to be a pattern here." Zhao Yawen stroked the stone wall and shouted at Cheng Yifan.

Cheng Yifan hurriedly got up and came to Zhao Yawen's side.

"Taijitu!" Cheng Yifan used a flashlight to illuminate a pattern on the rock wall and exclaimed.

"Press the yin and yang fisheye at the same time to open the channel." Old Ancestor's voice sounded in Cheng Yifan's ears again.

Cheng Yifan approached, pressed the yin and yang fish eyes at the same time, and waited in a panic. After a few seconds passed, everything was business as usual, nothing changed.

"Could it be that it is in disrepair, the mechanism is out of order?" Old Ancestor nagged.

As soon as the words fell, his feet shook a little. Then, a thick layer of dust floated up, and a "rumbling" sound came from the floor.

The slab cracked, and a bluestone staircase appeared on the ground, which extended into the ground, leading into the unknown.

Zhao Yawen asked in surprise, "How can you open the method of the tunnel?" ”

"I'm just going to try it, who knows if it can really open." Cheng Yifan smirked and covered up.

In order to avoid Zhao Yawen's suspicion, Cheng Yifan added: "I don't know where it leads, will it be an exit?" ”

"I don't know, according to the direction, it should be right, the entrance of the Luoxian Cave is at the foot of the mountain, it may be right to go down, let's go first, maybe it's really an exit." Zhao Yawen replied uncertainly.

Cheng Yifan nodded, stepped on the bluestone steps, flashlighted, and walked down cautiously; Zhao Yawen took Cheng Yifan's arm and followed closely behind.

No sooner had the two of them entered the passage than the slate moved again, and the cracked entrance closed again. At the same time, the torches on both sides of the passage were lit.

"It's actually phosphorus powder as a fire!" Zhao Yawen exclaimed.

The ancients covered the surface of the torch with phosphorus, sealed it for many years, and the methane gas was dense, and it was suddenly opened, and it was easy to spontaneously combust.

The fire flickered, and the bluestone steps were covered with a thick layer of dust, and the dust was loose, one step at a time, and it was obvious that this was a passage that no one had walked on for a long time; From the thickness of the dust, it can be inferred that this passage has not been walked for at least three or four hundred years.

Soon after entering the steps, Cheng Yifan and the others saw a spectacle: "A natural Tai Chi Yin and Yang Pool, suspended above the U-shaped groove of the cave. ”

And this U-shaped groove is the cave itself, and the highest point of the groove begins at the foot of Cheng Yifan, on a cliff at the entrance; The cliff is about 20 meters high from the bottom of the groove cave and is connected by 108 bluestone steps.

On the opposite side of the cliff is also a cliff, the shape and size are exactly the same as the cliff under the feet of Cheng Yifan; It is also made up of 108 bluestone steps, which start at the bottom of the groove and lead to another opening.

At the bottom of both cliffs is a half-meter-wide river, one end of which is directly below the mouth of the cave and the other end is connected to a large circular pool in the middle of the cliff.

There is an S-shaped retaining dam in the middle of the circular pool, which divides the pool into two yin and yang fish on the left and right, the color of the pool water on both sides is different, and the color of the pool water near Cheng Yifan is more turbid; And the side opposite Cheng Yifan is very clear. The natural Taiji diagram is really a miracle.

"I see, this is the true face of the fallen immortals, the wisdom of the ancients is really great!" Zhao Yawen sighed.

Hearing Zhao Yawen's exclamation, Cheng Yifan realized that Zhao Yawen must have seen something, so he asked, "Are you talking about the cause of the Falling Immortal Cave?" ”

Cheng Yifan was curious about the name of this cave when he entered the mountain, and asked Zhao Yawen about the origin of the name of the cave.

sold a smile and asked: "Teacher Zhao, let's talk about it, hehe"

Zhao Yawen made a begging gesture to Cheng Yifan and began to narrate:

According to legend, this Luoxian Cave existed long before the completion of Wuyun City. There is a clear pool in the cave, the pool water is sweet and delicious, can detoxify a hundred poisons, it is a good place for the mountain people to settle down in the past, because the mountain road is difficult to walk, and the villages are very remote, so the mountain people who pass through this place will choose to spend the night in the Luoxian Cave.

One night hundreds of years ago, a procession passed by the cave and stayed overnight. In the middle of the night, the bride felt thirsty and ran to the pool to fetch a bowl of water, who knew that after drinking the water, the bride would become insane.

She claimed to have seen a beautiful man with a good demeanor, who had been standing stupidly by the waterhole, with blank eyes and a strange smile. The people of the welcoming team were frightened, it was a clear pool that could cure all diseases, why did this bride become like this after drinking it?

They searched around, but they did not find the man in the bride's mouth; However, when they approached Qingtan, they heard a message from underground, "The pit... Pit... The sound of the pit" turned the originally clear pool water into turbid and dirty water.

They were so frightened that they didn't dare to stay, and they fled from the cave with their brides overnight.

After the bride returned home, she kept smirking like crazy, refused to have sex with Xinlang, and secretly ran back to the Luoxian Cave several times.

The family was very anxious, and invited several Langzhong, but they couldn't see what the illness was; I ate a lot of herbs and didn't get better.

People in the village said that she had come across something unclean in the cave and had her soul taken away.

So his family, climbing mountains and wading through rivers, invited a witch doctor from the mountains.

The witch doctor said that the bride was snatched away because she disturbed a fallen immortal in the cave, Qing Xiu; This immortal had been framed, lost part of his immortal arts, and fled to this cave to practice.

The witch doctor asked the bride's family to make offerings of food and clothing and throw them into the murky water; And tell them that if the immortals forgive the bride, they will accept the offerings, and the water of the pool will become clear again.

The enshrined items floated in the pool for a day without response, and the bride's family knelt by the pool to atone for their sins. It may be that the immortals were really moved, and that night, the water in the pond actually flowed upstream, and the items offered to them also flowed into the depths of the great cave with the water flowing backwards. What's even more strange is that not long after the offerings flowed away, the water in the pool was clear again.

The witch doctor asked the bride's family to fetch a bowl of water from the pool, and the bride came to her senses after drinking the water.

According to the bride's own account, she really saw a fairy in white by the waterhole that night. The fairy smiled at her as he flew past the waterhole, and then vanished.

The witch doctor told them that the waterhole was the embodiment of the mortal mind of the immortals, and that the turbid water was his grievance, and that those who accidentally ate the water would be swept away from their souls, vomiting and venting, or going crazy and stupid. And the clear pool water is transformed by his immortal energy, which can cure all kinds of poisons, smelt all kinds of diseases, and strengthen the body and bones. The resentment was originally sealed, but it was only because the bride disturbed the immortals that the resentment leaked out, and the immortals became moody from then on.

The news spread quickly, and at first there were many people who did not believe it. Later, more and more bizarre things like this happened, and people had to believe it.

Later, in order to suppress the resentment, people made a stone statue by the waterhole to worship. The stone statue was named "Luoxian", and the Luoxian Cave was also named after it.

Strange to say, since then, the waterhole has often become cloudy in autumn and winter, and each time the offerings have flowed away, they have been cleared again.

"It's amazing!" After listening to the narration in a daze, Cheng Yifan sighed in surprise.

"Hehe, there's nothing magical, everything has roots, it's just that people don't know it." Zhao Yawen smiled lightly.

"You must have found something? Let's talk about it again. "Cheng Yifan sells cuteness.

"Is there any reward, hehe," Zhao Yawen said with a smile.

"I'll roast a roast chicken for you to eat." Cheng Yifan brought out the ridicule of the ancestor.

Zhao Yawen smiled, then looked at the Taiji pond in front of him and said: All the magic originates from this Taiji big round pool.

"The cathode is anti-yang, the anode is yin, and the yin and yang follow each other."

This Tai Chi pond is the confluence of two rivers.

The turbid side is fed in by the previous cold pool, or even further underground rivers, and is regarded as the cathode. Due to the dark area where the underground river flows, the water quality is very poor and even poisonous.

On the clear side on the opposite side, the river water comes from outside the Luoxian Cave and is regarded as an anode, and the water quality is better and suitable for drinking.

Zhao Yawen pointed to the S dam in the middle of the Taiji Round Pond and said to Cheng Yifan: "Do you see the holes at both ends of the S curve?" ”

Cheng Yifan looked at it and nodded.

That is the inlet of the pond water on both sides, and the water level of the two rivers is different due to the difference in the amount of water injected.

In autumn and winter, there is little rain, there is more water in the underground river, the water level of the cathode pond is higher than the anode, and the turbid water flows into the anode through the hole, and then flows into the clear pool of the Luoxian Cave, so the clear pool becomes a turbid dirty pool.

At this time, what Cheng Yifan saw was the turbid dirty water flowing out of the Luoxian Cave.

Immediately afterwards, Zhao Yawen said: "Now that it is raining outside, it should soon be more water than the underground river outside the mountain." ”

Sure enough, Zhao Yawen's voice just fell. The river suddenly flows backwards, and clear water flows out of the opposite hole, through the anode pool, into the cathode pool, and finally into the underground river.

"This is the cathode anti-yang, and the yang moves and the yin follows." Zhao Yawen pointed to this appearance and sighed.

"This girl is more than ten times smarter than you, and she knows a lot. Stinky boy, take her, you will have no worries for the rest of your life, haha. "The ancestor admired.

After Cheng Yifan secretly scolded him in his heart, he continued to ask Zhao Yawen: "What's the matter with the white-clothed immortal?" ”

"You can try it clearly." Zhao Yawen said with a smile.

"I can't figure it out." Cheng Yifan shook his head with a helpless smile.

Zhao Yawen knocked on Cheng Yifan's head, and after scolding a stupid person with a smile, he asked rhetorically: "Don't you think what happened to that white-clothed immortal is very similar to the ancestor?" ”

"Oh!" Cheng Yifan suddenly realized, and after reasoning about the whole thing, he said with a smile: "Mo Fei, the white-clothed immortal that the bride saw back then was the ancestor. ”

"Boy, what nonsense are you talking about, I haven't gone out since I came here, and it's impossible to see any brides." The ancestor cursed in his stomach, and then bit down on Cheng Yifan fiercely.

"Only half right, hehe." Zhao Yawen smiled and shook his head.

Then she continued: The woman saw the family surnamed He who built this round pool, and the "pit... The sound of the pit is the sound made by the He family when they built this cave.

"Isn't this waterhole natural?" Cheng Yifan asked a puzzled question.

"Half natural, half artificial. The S-shaped dam and the water outlet were added later, because the water in the cave was not turbid before the bride discovered the white-clothed immortal. ”

"That is to say, when the bride was drinking water in the middle of the night, she happened to meet the engineering jun, and the man in white probably went out to check the situation of the pond." Zhao Yawen explained.

"According to this, the witch doctor is also from the He family; The so-called fallen immortals are just a cover thrown by the He family to divert people's attention; And the original body of the fallen immortal is the ancestor. "Cheng Yifan's brain is open, and he is perfectly connected.

"Hehehehe, isn't it good, the son can be taught, hehe." Zhao Yawen covered his mouth and laughed and praised Cheng Yifan.

Cheng Yifan scratched his head and smiled embarrassedly: "Those who are close to Zhu are red, and those who are close to Zhu are red." ”

"Hehehehe." Zhao Yawen is still smiling and welcoming.

"I think that the purpose of the He family's cultivation of this yin-yang pool at that time was to transport things to the cold pool; Unexpectedly, he was bumped into by someone, so he made up a lie of the immortals, so that the delivery of materials could be carried out in the name of sacrifice and worship. Zhao Yawen summarized the story to the end.

Gently pushing Cheng Yifan forward, Zhao Yawen pointed to the opposite hole and said, "Let's go, the exit is ahead, and you can finally see Gao Yunliang and them." ”
