The cliff was about two hundred meters high, and the cave was about fifty or sixty meters above the ground a third of the way off the ground. With such a height and steep rock walls, it's not something that anyone can climb up if they want to.

Ning Tao stood under the cliff, looked at the vertical and steep cliff, and asked: "Lady, this cliff is so steep, that cave is so high, you were so small back then, what are you doing when you climb up, aren't you afraid of falling?"

"I climbed up to play, because I was young, I wasn't afraid, but when I grew up, I didn't dare to climb up. Kunlun Yu said.

People are like this, young and fearless, and the older they get, the more afraid they are of death.

"I'll go up and have a look. Ning Tao left this sentence, jumped up, his body swooped up more than ten meters high, and when his body was about to fall, he leaned on the cliff a little, his body jumped up again, and after a few steps, he reached the mouth of the cave on the cliff in a blink of an eye.

"Brother-in-law!" came Hei Yuchong's voice from under the cliff, "You must teach me this light skill!"

"Okay!" Ning Tao replied and walked into the cave, his eyes and nose also entering a state of looking and smelling.

With the location and height of this cave, the people who can carve patterns and symbols here cannot be ordinary people, not to mention the existence of aura here.

The entrance of the cave is a crack in a rock in the cliff, in the shape of a "human". Entering the cave, the space inside suddenly opens up, but it is still a crack between the rock plates, and the rocks hanging overhead, giving the feeling that they may fall at any moment.

The cave stretched forward, and the further you went, the darker the light became, but this had no effect on Ning Tao. He didn't go far before he saw the patterns and symbols that Hei Yuchong and Kunlun Yu were talking about.

When Kunlun Yu talked about the patterns and symbols in this cave, he had a natural conjecture in his mind, that is, it might also be the runes and patterns of the Heavenly Family, or it could be the information related to the Book of Heaven left by the ancient god who guarded the Zhaoye Clan. However, what appeared in front of him was something plausible, some like square words, some like animals, and some were simply meaningless lines.

After seeing more patterns and symbols, Ning Tao feels more and more like the "Hongyan Heavenly Book" in Anshun, Guizhou. It's just that the patterns and symbols here are not red, they are black, as if they were etched into the rock wall with thick ink.

These patterns and symbols are definitely not naturally formed, because it is these patterns and symbols that are the source of the aura that permeates this cave.

"Could it be that the ancient minority cultivators carved it here? Using a spiritual material pigment similar to the incense of the Buddha?" a guess popped up in Ning Tao's heart, and he reached out to touch a rune-like existence, moving his fingers along its half-finger-deep lines.

Suddenly, something flashed through his mind.

At that moment, it felt like there was some information transmitted to his mind through this touch, such as a voice, an image, but when he wanted to see the effect clearly, hear the sound clearly, there was nothing in his mind.

Until he walked his fingertips over all the rune-like lines, the strange feeling just now did not appear again.

He then moved on to another pattern that looked like a seahorse, and ran his fingers over the lines. Soon, the feeling of a voice or an image flashing through his head came back again, fleeting, too fast for him to capture.

"This ......" Ning Tao was surprised and confused in his heart, this was the first time he had encountered such a strange thing, obviously there were sounds or images flashing through his mind, but he couldn't capture anything.

In fact, with the current speed of his brain's response, even if one of the insects chirped differently, he could instantly recognize it. Even if a bullet flew in front of his eyes, he could see it and remember the image. However, a voice and image that had entered his brain, but he couldn't remember anything.

He touched a third rune-like symbol, the same result.

He frowned, do you want to invite Worm Er out?

"Husband. Kunlun Yu's voice came from the entrance of the cave.

Ning Tao put away his thoughts and looked at Kunlun Yu and Hei Yu Chong walking towards this side from the entrance of the cave. Hei Yuchong was still holding a fire fold in his hand, illuminating his vision with a small dark fire.

The siblings are also good, but they can't compare with him.

"Brother-in-law, this place is good, it's just right for you to teach me peerless martial arts. Black Jade Chongle said.

Ning Tao said: "It's good, but this place can't come again." ”

"Why?" Hei Yuchong had a strange expression on his face, "Could it be that those old men are really saying that this is an ominous place?"

Ning Tao said: "I don't let you come, not because this place is an ominous place, but these symbols and patterns are carved by people, a bit of an evil sect, your ability is limited, in case you touch something, or get contaminated with something, it is not a good thing for you." ”

Hei Yuchong nodded, looking teachable.

"Husband, what do these symbols and patterns say?" Kunlun Yu asked, his eyes full of expectation.

Ning Tao shook his head: "I don't know for the time being, I have to think about it." ”

Kunlun Yu said in surprise: "Even you don't know?"

Ning Tao smiled: "I'm not an omnipotent god, of course there will be things I don't know." Also, the universe is so vast that even a god can't know everything. ”

Kunlun Yu was stunned, as if pondering Ning Tao's words.

Ning Tao continued to walk forward, touching symbols and patterns that he had not touched, and this time his fingers had a little spiritual power on them. But it didn't work, the feeling of the sound and the image suddenly appearing in his mind was the same, fleeting, and he couldn't recall anything.

"Could it be that there is any magic circle seal?" another guess popped up in his mind.

"Husband, what are you doing?" Kunlun Yu said curiously.

Ning Tao didn't stop walking, touching as he walked, and spoke: "Lady, how many years has this cave existed? Who first discovered it?"

Kunlun Yu said: "My father said that this stone mountain is always there, and it has a longer history than our Zhaoye clan, as for who discovered it, there is no way to know, but I think it must be the ancestor of our Zhaoye clan." ”

Ning Tao walked to the other side of the cave and continued to touch the patterns and symbols on it. Even if it was fleeting and unkept, he had to touch it all. Although he can't figure out what is going on now, it doesn't mean that he won't have a chance in the future. He had a vague feeling that the patterns and symbols in this cave might be related to the Book of Illuminating the Night. Is it a coincidence or something else that a small minority in the Western Regions has two extraordinary things at the same time? This is also what he wants to figure out.

The last rune-like symbol was touched, and Ning Tao counted it in his heart, a total of forty-nine symbols and patterns. Eventually, he saw a fossilized shell next to the symbol, embedded in the rock, very clearly.

This place used to be the sea.

It is true that the history of this cave is much older than that of the Teriya, and it is impossible for the Teriya to evolve directly from the sea.

Ning Tao returned to Kunlun Yu and Hei Yu Chong's side and asked, "Have you ever touched these symbols and patterns?"

"Of course I did. Kunlun Yu said.

Hei Yuchong simply touched a beast-like pattern beside him, and said with a smile: "Brother-in-law, don't I touch this, I also touched it when I was a child, but I didn't receive any curse." ”

He clearly didn't believe there was some ominous place here.

Ning Tao asked again: "Then do you have ...... When you touch these patterns and symbols, do you hear any sounds or images that flash through your mind?"

Black Jade Chong shook his head.

Kunlun Yu had a strange expression on her face: "Husband, it's so strange what you asked, did you hear any sound when you touched these symbols and patterns?"

Ning Tao said: "Yes. ”

"What did you hear?" Kunlun Yu suddenly became excited.

Ning Tao said: "I heard the mountains shouting, who is the most beautiful woman of the Zhaoye Clan? I heard the desert responding, it is Kunlun jade, it is Kunlun jade. ”

Kunlun Jade: "......"

Hei Yuchong had a bewildered expression: "Brother-in-law, this is amazing, is that really what the mountains and deserts say?"

Ning Tao: "......"

Kunlun Yu slapped the back of Hei Yuchong's head: "You believe this, your head is really filled with sand!"

Heiyu glared at Kunlun Yu: "You beat me again!Brother-in-law, you don't care?"

Ning Tao smiled and said, "Let's go, we should go back." ”

Back to the Zhaoye tribe, Ning Tao taught Hei Yu Chong two tricks of cat's claw boxing, and Hei Yu Chong ran to the jujube forest behind the house to practice boxing. Kunlun Yu went to cook, and Ning Tao stayed in her room, drawing all the symbols and patterns on the cave walls with memory.

I've painted, seen, and pondered, but I still don't have a clue.

Ning Tao also took the Book of Heaven in the Night, and compared the Heavenly Runes in it with the symbols and patterns drawn by him. His wish was to find a clue to the crack, but he couldn't even find a thread after working for a while. The symbols and patterns on the cave walls were not Heavenly Runes at all, if he could have seen it at the time.

Even if he had no clue, he didn't finally invite Worm Er out to help him solve the problem. He even endured the book of the night sky, and didn't invite the second worm to come out, so there was no need to invite the goods out of these symbols and patterns.

Then, he put away the symbols and patterns drawn by the book and left the house: "Lady, I'll go for a walk on the edge of the black pool." ”

"Don't go far, it won't be long before I'll be able to cook here. Kunlunyu's voice came from the kitchen.

"Okay, I'll just walk around. Ning Tao walked to the black pool alone.
