Cheng Tianle turned around and drilled in, stepping on the mud and stagnant water in the dark, the terrain here is like a gourd with another gourd, walking about 100 meters away, the space is getting wider and wider, but on the way to pass through several faults and ravines, as well as the undercurrent that is very deep underground, if you step into it will be very dangerous, ordinary people will never be able to pass.

How could there be so much tawny mud in the cave? It is possible that there are stone crevices in the mountains, and rainwater can seep down to keep the mud moist and silt up in low-lying areas. At this time, Cheng Tianle smelled a faint fragrance, which came from these mud piled up in an unknown age, and couldn't help but think of the local legend that "the ancient cave has fairy qi and mud can cure diseases".

If it weren't for Cheng Tianle's perceptual sensibilities, and he was particularly familiar with some of the ingredients in this breath 404, piercing the phantom wall, and the cave in the pot, I am afraid it would not be easy to smell, because it was already so faint that it was difficult to detect. This aroma contains the smell of cold needle emerald and refining dragon marrow, it seems that this place is definitely the cave of Yu Daoyang's predecessor, many years ago, he refined Lu Wu Shenlun Dan here, so he will leave this breath.

Cheng Tianle finally took out the jade pendant and urged it with the method of imperial weapons, and it floated in front of him, emitting a soft moon-white light. This thing is not only a spiritual inducing artifact, but also has a wonderful use, that is, it can shine with mana in the dark. Cheng Tianle smelled the breath left by the suspected refining of Lu Wu Shen Lundan, so he took out this magic weapon that could open the cave.

Standing in the cave and looking up, the top of the cave presents a stalactite shape like white clouds, and there are many stalagmites like human shapes on the four walls. Look ahead, the ground is no longer silt. The stones on the ground were scattered like flowers and trees.

Continuing to move forward for dozens of meters, Cheng Tianle had already zigzagged in the cave for nearly a mile, passing through the narrow passage between the stalagmites as thick as a large column, and the space in the cave became open again. Under the soft light of the jade pendant, the stalactite wall in front of it is like a 404, piercing phantom wall, the cave in the pot has a waterfall pouring down, and the stalagmites half integrated into the rock wall are combined into the shape of a waterfall. The cave seems to have come to an end here, but there are still forks in the rocks on both sides of the waterfall. I don't know where it leads.

Cheng Tianle didn't turn around again, but held the suspended jade pendant in his hand, and suddenly rose into the air. Performing the magic method, the foot of the stone waterfall flew up to a height of three feet. Near the top of the cave, stalagmites stretching upwards and hanging stalactites are staggered. It's like the mouth of a monster, and there is no passage in the middle of the mouth or a stone wall.

But seeing that Cheng Tianle's flying body was castrated, he actually crashed headlong into the stone wall, did he want to test how hard his head was here? Then an incredible scene happened, the stalactite wall was in a trance, rippling ripples like the surface of the water, Cheng Tianle directly penetrated the stone and disappeared, as if swallowed by the monster's huge mouth out of thin air.

The mountain wall above the stone waterfall, if you don't pay attention, you can't find any flaws, but under the light emitted by the jade pendant, you can investigate it with your divine sense, and it is actually a magic circle arranged by using the earth qi spirit center. Cleverly create a "phantom wall" formed by the refraction of light and shadow. There was originally a hole there, but it was just invisible, and the jade pendant was spontaneously sensed at this time, and the spatial scene behind the stone wall naturally appeared in the Heavenly Happiness Yuan Shen, so he jumped in through the phantom wall. It's like disappearing in this cave.

The place he came to was another cave hall with a hole connected to the hall below the stone waterfall, and the ground was higher. The air here is still at a constant temperature all year round, but it is drier and less humid than elsewhere; The ground is very flat, and it has been manually chiseled, and there is a Dan furnace in the middle of the hall. Cheng Tianle understood that this should be the place where Yu Daoyang's predecessors refined the elixir, and it was connected to the outside space. No wonder there was a faint medicinal scent in those muds.

Walking around the incense burner, passing through a stone door that opens on the wall of the cave, inside is a very neat stone room, about two zhang square, not naturally formed but artificially excavated. Wooden shelves and cabinets are placed on both sides, and there are beds and cushions in the room, which is obviously a retreat room for monks in ancient times. Some things have decayed and semi-dusted, and some things are still very well preserved, especially many bottles and cans are still intact.

But this place has come to an end, except for the portal and the stone walls on three sides when he came, there is no passage, as if the ancient Yu Daoyang's predecessor's cave is here, but he himself is long gone.

Cheng Tianle didn't rush to use any magical means, but just carefully searched the stone room without touching the animals. On the front wall, a line of writing was written, and the ink seemed to penetrate deep into the stone, and it was still clearly visible hundreds of years later.

"Those who get the Dan prescription in the West Sichuan Cave Mansion can be my disciples. Let's go to Gusu Huqiu Yunyan Temple to find Master Zhongsu, who has the method of taking the divine pill and the method of passing on the method. - Yu Daoyang"

Now the Tiger Hill Yunyan Temple has long been gone, and Yu Daoyang did become a monk in the Yunyan Temple hundreds of years ago. If another person comes here and sees the words on the stone wall, he will definitely think that Yu Daoyang has already left, and if he wants to find him, he will also go to Gusu to find clues, this is all the cave. Only those who got the last message in the stone beaver statue knew that Yu Daoyang planned to return to this place after escaping from Gusu that year.

Did he escape back then? If he hadn't come back, the handwriting would have been there. If he had returned, why had he kept it and not erased it? If the uninformed come here, they will naturally think that the person is no longer there, and they will not bother too much to find it.

Yu Daoyang also mentioned "Sichuan West Cave Mansion" and "Danfang", "Shendan", and "Zhengchuan Fa Jue", which contains a lot of information in just one line! It seems that this predecessor has the style of the three caves of the cunning rabbit, and has successively cultivated the "cave house" in western Sichuan, Liaodong, and Suzhou. Western Sichuan should be his earliest place of practice, and there is a Dan Fang of Lu Wu Shen Lun Dan in the cave, and he guides the heirs to Liaodong to find him.

After he left Liaodong to go to Gusu, he also came back and left a message in the cave here, informing him that the heirs he might find went to Suzhou to apprentice. The true recipe mentioned in the message should be the recipe that he later left in the stone beaver statue and was obtained by Cheng Tianle more than 500 years later. Looking at this line of messages, it shows that from the Ming Dynasty to the present, there should be others who may have been here.

After examining the other items carefully, Cheng Tianle found that there were still traces of someone coming, and to his surprise, the time of the visitor's visit was only a few years ago, even after the reporter's news report!

Although the cave is very clean, it still leaves a very thin layer of floating dust over the centuries. The shelves leaning against the two walls seem to be of yellow pear texture and have undergone simple mana treatment, and they are very well preserved after hundreds of years, and they will definitely sell for a lot of money if they are taken to the antique market outside. Some of the books on the shelves, the paper seems to be complete, but in fact they are rotten and brittle and cannot be turned over; There are also a lot of bottles and cans, all of which are empty.

Next to these empty cans, there are still round traces left on the floating dust, which means that there were also medicine bottles there, but they were taken away, and there are more than twenty of them! The traces are very new, and it is inferred from the comparison between Chengtian Letong guò and the floating dust next to it, and there is a unique feeling and artistic conception of the years, and it is basically determined that the time for someone to take away the medicine bottle will never exceed four years.

But Cheng Tianle didn't find any traces left by this person on the way into the cave, presumably that person also had a magical power, and he didn't touch any items or leave a trace of breath along the way, but he came to this stone room and took things, but in the end he left traces. Cheng Tianle had a flash of inspiration in his mind, and suddenly thought of a person - Liu Yanghe!

Liu Yanghe used to be an ascetic loose cultivator in the Sichuan-Tibet border plateau, and Yu Daoyang's predecessors had a cave in western Sichuan, which was probably discovered by Liu Yanghe occasionally, and obtained the Danfang of Lu Wu Shenlun Dan in the cave, and found this place according to the guidance left by Yu Daoyang. Although the topography has changed a lot today, there happened to be a reporter who wrote such a report at that time, and Liu Yanghe could search if he was careful, and he found this ancient cave.

There is the Dan furnace outside the stone room, which should be the place where Yu Daoyang's predecessors did alchemy, and the bottles and jars stored in the stone room should be the various elixirs for refining Lu Wu Shenlun Dan, all of which were taken away by Liu Yanghe. No wonder this person will refine the Lu Wu Shen Lun Dan, maybe he has already refined it and wants to continue refining, but looking at the message of Yu Daoyang's predecessors, Liu Yanghe still doesn't fully understand the mystery of taking this pill.

Cheng Tianle was smiling bitterly in his heart, feeling a little absurd inexplicably. According to the divine message left in the stone beaver statue by Daoyang's predecessors, the person who obtains the magic is his living heir; Looking at this message again, the person who got the Danfang in the West Sichuan Cave Mansion is also his descendant disciple. So from this relationship theory, wouldn't Liu Yanghe and Cheng Tianle become brothers? If this pair of brothers and sisters meet again, how should this bad debt be calculated, do you agree with the door first and then do it?

If Cheng Tianle wants to kill Liu Yanghe, he will have to pay homage to Daoyang no matter what.

Cheng Tianle once obtained a set of nine jade bottles in the Lianyun Sect, which were specially refined magic vessels for holding elixirs, and then looked at the remaining bottles and jars on the shelves, all of which were ordinary porcelain from the Ming Dynasty and were not illegal treasures. It seems that the more precious and valuable things have been taken away by Liu Yanghe, and there are too many things here, and he can't empty them all at once.

After making sure that there was nothing else missing, Cheng Tianle concentrated on breathing and calming his mind, holding the jade pendant towards the stone wall with handwriting on the front of the stone chamber, and at the same time using his mana to urge the spirit in the jade pendant. I saw that the handwriting and stone lines on the stone wall were hidden, and they became smooth as a mirror under the light, and a green bamboo relief image appeared in the center. rq！！！
