A few steps into the cave stands a stone monument with the warning "death to trespassers". The light passed over the stone monument, and the cracks and passages between the rock walls were twisted and curved, and it was impossible to see what was going on inside.

Ning Tao's heart was a little worried, "Could there be any traps, or magic circles or something?"

Xuantianzi's Taoism is profound, and old demons like Yin Molan are very jealous, and even say that he has ascended to immortality, and if his cave is equipped with traps and magic circles or something, then the danger index is not ordinarily high.

But it's all here, it's impossible to turn around and flash just because you see the sentence "The trespasser is dead", right?

Ning Tao took his mobile phone and walked cautiously towards the depths of the cave. The lights flickered, the footsteps echoed through the silent caves, and some rocks were like ghosts and beasts lurking in the darkness, ready to pounce on him at any moment to strike a fatal blow to the trespasser.

At first, he walked horribly, but after no accidents happened, his tense nerves relaxed a little. Through the zigzag crevices, a cavern inside the mountain appeared in front of him.

It's not big, about the size of a screening room that can seat hundreds of people to watch a movie, with a wide space at the bottom and a small space above, shaped like a hat on the top. The height of the bottom of the cave and the top of the cave is about 30 meters, and the stalactites hang down, like a piece of bamboo shoots growing upside down, some are big and long, and some are squeezed against each other to form a strange shape. There are many small holes carved in the stone wall upward, round and round, like honeycombs, but I don't know what they are for.

"It doesn't seem dangerous. Ning Tao thought to himself, and stepped into the cave floor from the end of the passage.

But it was this kick that suddenly sank a little bit of ground under his feet. He subconsciously raised his head, and at that moment, the sound of something rolling suddenly came from the artificially dug round holes on the top of the cave, and then the large and small stones fell like raindrops!

He had been wondering what those round holes were for, but now he knew that they were falling stones.

In a panic, Ning Tao jumped back with his feet a little.

Bang!

A boulder suddenly rolled out of the side of the passage behind him, blocking the way back.

Ning Tao's back hit the boulder, and it was bounced back under the reaction force. His sense of crisis climbed steeply to a critical point, spiritual power rushed out from the Mud Pill Palace, and the spiritual power qibag was instantly completed. At that moment, a stone several times larger than his head fell on his head.

Boom!

With a muffled sound, he was smashed to the ground, and his skull seemed to be about to crack. In desperation, he threw his waist back, and as the stone fell from the top of his head, his back pressed against the boulder that sealed the passage.

Bang!

Another stone was on the instep of his foot, and his mouth was open, but nothing came out.

Boom, boom, boom......

Cobblestones fell from the top of the cavern, smashing the ground and trembling. That density, that area, not to mention people, even a bird can't escape this stone rain!

If Ning Tao hadn't practiced this true cultivation skill, his life would probably have been explained here.

The stone rain stopped, but Ning Tao was still clinging to the boulder, and there was a cold sweat on his forehead. The terrifying experience just now also made him make up his mind that if he ventured into a similar place in the future, he must be fully prepared before entering. Just now, if it wasn't a stone that fell, but a spear or something, he would have died, who would he seek revenge?

After a few minutes of stupefiing, Ning Tao moved away the stone that was still pressing on the instep of his foot and continued to move forward.

The ink in the inkstone spilled out when he dodged the stones, but he didn't need it anymore. Entering the inner space of the cave, Ning Tao didn't go far when he found a small field paved with spiritual soil, with an area of at least a dozen square meters!

This situation is indeed normal, Xuan Jizi is the owner of the earth-seeking inkstone, if he lives for one or two thousand years, it is not surprising that he uses the earth-seeking inkstone to find so much spiritual soil.

There are also several spiritual materials planted in the small spiritual field. He carefully distinguished, and there was a ginseng plant with colorful leaves, and the light was full of colors, which was very magical. A wolfberry has dozens of black wolfberries on it, each of which is crystal clear, like black jade beads. A radish, the leaves are white, and a little radish exposed outside the spiritual soil is green all over, like jade. There is also a green onion, which is blood-red all over, and the color and texture are like the best blood coral.

However, this is only Ning Tao's judgment based on the shape characteristics, as for whether these four spiritual materials are ginseng, wolfberry, radish and green onion, it is unknown. His cultivation knowledge was too lacking and needed to be recharged.

"The clinic space is small, and there is no place to put the spiritual soil back, so it is better to stay here and let the spiritual materials grow here. The spiritual soil in the clinic can also be obtained here, and the planting area can be expanded. Ning Tao thought so in his heart.

After stepping through the "Lingtian" and walking forward for a while, a stone gate opened on the cliff wall entered Ning Tao's sight.

The stone door was closed, and he tried to reach out and push it. I thought I couldn't push it, but this push stone door opened. As the stone door slid inside, he shrewdly jumped to the side, dodging the hidden weapon that might shoot out from inside.

No hidden weapon shot out of the stone door.

Ning Tao returned to the door and took a flashlight on his mobile phone, and he was stunned on the spot.

Behind the stone door is a room with a stone table and bookshelves filled with books and bamboo slips. There was also a stone bed, on which sat a dried corpse sitting cross-legged.

The corpse's face was left with only a layer of skin, its eye sockets were sunken, and there seemed to be nothing behind its eyelids. His clothes had long since weathered, and there was a dimple in his bare chest, which looked like he had been slapped in the ribs. He held a fan in his right hand, and the fan was still intact, except that a few of the fan bones were broken, and the paper that stuck to the fan bones was also broken.

Ning Tao was stunned for a long time before coming back to his senses, he cautiously walked into the stone house, and he was also pondering a question in his heart, "He can't be a mysterious machine, right?"

Yin Molan said that Xuan Tianzi had ascended to immortality, if this dry corpse sitting cross-legged on the stone bed was Xuan Tianzi, then he was not ascending to immortal, but ascending to heaven.

Ning Tao's conjecture soon became true, and there was a jade pendant hanging from the waist of the dry corpse, and the jade pendant was engraved with the words "Xuantianzi". That is, in the process of taking a closer look, he also determined that Xuan Tianzi's chest had indeed been hit hard, and his ribs were broken three times, one of which was pierced into the place where his heart was.

Xuan Tianzi's death was clearly related to the injuries he suffered in the chest.

Ning Tao took off the fan in Xuan Tianzi's hand, and started with a heavy one, the fan bones were all made of spiritual metal, and it was cold and piercing. Fan paper is also not ordinary paper, but is woven from plant fibers. After opening it, the word "unbreakable" was written on the fan.

Ning Tao smiled bitterly, "What can't be broken, it's all rotten like this, what else can you say that can't be broken?" But this fan is cold, take it back and use it to make up for it with the rotten ding, and it can also be used as an air conditioning fan, and it will be a cool breeze if you fan it." ”

I don't know how Xuan Tianzi felt when he heard Ning Tao say this.

Ning Tao stuck the unbreakable fan on the waistband of his trousers, and just as he was about to go to the bookshelf to see if there were any books that could be used for cultivation knowledge, he suddenly found that there seemed to be something sitting under Xuan Tianzi's buttocks, and only one horn was exposed.

"Xuantianzi senior, offended. Ning Tao reached out and grabbed the horn and twitched it.

Crash!

Xuan Tianzi's bones suddenly collapsed, his arm fell off, his ribs collapsed, and his head rolled off his neck, rolled twice on the stone bed, and then fell to the ground.

Ning Tao opened his mouth wide and closed it after a full ten seconds, and then said again, "I'm sorry." ”

Xuan Tianzi's butt was pressed with a piece of spiritual paper used by cultivators to draw talismans, which was made of bamboo pulp from spiritual bamboo and would not be weathered for thousands of years. This paper is extremely precious, much more advanced than the special prescription slip used by the Extraterrestrial Clinic to write prescription contracts.

Ning Tao opened the spirit paper and looked up.

It is written on the spirit paper: This Dao Xuan Tianzi has a long life, and he is only one step away from crossing the tribulation and ascending, but he can only regret it for life. In the ancient era of Linggu, heaven and earth were full of spiritual energy and rich spiritual materials, and as long as a person who cultivated the truth had understanding and worked hard enough, he would have the opportunity to cross the last barrier and enter the immortal world. But now that the spiritual energy of this world is thin, and the cultivation resources are extremely scarce, even if the cultivators have the resources to cross the barrier and enter the immortal realm.

What is even more hateful is the lack of aura, the desire for demons to grow wildly, creating countless new demons, and harming the world. In the long run, the world is in danger. Ben Dao has slashed countless demons and demons in his life, defending the right path in the world, but in the end he still missed. A group of new demons from the West set a trap and used the new demons as bait to harm Bendao in an ambush, and Bendao fought out of the encirclement but knew his fate soon.

This testament is left by this Dao, and the person who sees this suicide note is the successor of this Dao Cave Mansion. There is only one last wish of this way, and the leader of the new group of demons is called Adolf Sid. If you remove it, the spirit of the Tao in heaven will be at peace.

The mountainside stone forest is the magic circle left by this way, but unfortunately the lack of spiritual energy has become invalid. There is a secret passage under the square stele, and a secret passage under the stone bed is connected. The entrance to the cave is closed, and the secret passage under the bed can be used to enter and exit the cave.

The suicide note was signed by Xuan Tianzi.

"Adolf Sid?" Ning Tao stared at the name of the new demon leader on the suicide note, not knowing why he thought of a terrifying character, Adolf Hitler.

Although Xuan Tianzi did not specify when he died, in terms of the degree of weathering of his corpse, it was hundreds of years old, how could the new demon leader who set up an ambush and booby trap be Adolf Hitler?

Ning Tao picked up Xuan Tianzi's head and put it on the stone bed, and then bowed deeply to Xuan Tianzi's bones, "I am the master of the Tianwai Clinic, and it is my business to do the Tao for the sky, if the Adolf Sid that my predecessor said is still in this world, I will definitely avenge you and kill him." After a pause, he added, "I want to put my predecessors in the ground, but my seniors have no opinion, right?"

Xuan Tianzi obviously didn't have any opinions.

"Okay, I'll bury my predecessors another day. Ning Tao bowed to Xuan Tianzi's bones again, and then went to the bookshelf.

The books and bamboo slips on the shelves are all related to Xiuzhen, and they are all handwritten.

Ning Tao took down a copy of the "Compendium of Spiritual Materials", and then sat at the stone table and flipped through it. In the book, he found a description of the four spiritual materials planted in the "spiritual field" outside, and the colorful ginseng is called colorful ginseng, and only the canyon with frequent rainbows and abundant spiritual energy can give birth to colorful ginseng. The white-leafed radish is called the jade radish, and only the jade mine with aura can be bred. The blood-red green onion is called the corpse onion, and it can only be conceived on the ancient battlefield where the bones are piled up. The wolfberry is called the Devil's Kidney, and it can only be conceived on the graves of the most vicious.

These four spiritual materials are extremely precious, and they are all the best spiritual materials for refining pills. Especially the demon's kidney, people with kidney deficiency only need to eat one to get rid of the deficiency and regain their virility.

Seeing this, Ning Tao immersed himself in the knowledge of the "Compendium of Spiritual Materials", and did not draw a blood lock to leave Xuan Tianzi's cave until the mobile phone ran out of power.

Now, the cave mansion of Sword Pavilion Mountain is also his cave mansion, and he doesn't go through any secret passages under the bed at all.
