On the cliff, a large group of Shennongjia savages stood in a row and looked at Ning Tao in the dark cave. In that picture, a group of onlookers with stones and wooden sticks who did not know the truth were alive.

"Roar, roar, nest ......" The Shennongjia savage who kicked Ning Tao away waved his arms, and the voice that came out of its mouth seemed to be a sentence, but except for themselves, the whole world may not find anyone who can understand.

"Hahaha!"

"Ho ho ho!"

"Yo he...... Yo yo!"

There was a burst of laughter, and a shout of a mountain song, which seemed to be amused by the words of the heroic compatriot. And Ning Tao, he has disappeared into the darkness where he can't see his fingers.

People probably have a dream of flying, but if they really fly, it will definitely not feel good.

The wind whistled in his ears, and the gravity of the center of the earth was like a huge rock tied to his feet, carrying Ning Tao down into the dark abyss. In the first few seconds, Ning Tao's heart was full of fear, his brain was blank, and he didn't know what to do.

But just when the fear climbed to the limit and was about to collapse, the huge pill in Ning Tao's Mud Pill Palace suddenly trembled, and the spiritual energy field instantly spread out in his body, and he calmed down in that instant.

Ordinary people must be dead when they encounter such a situation, but he is a natural intermediary between good and evil, the master of the Extraterrestrial Clinic, how could he die like this! Ordinary cultivators' survival ability is much stronger than that of ordinary cultivators, not to mention a special cultivator like him who only comes out once in 2,000 years!

Spiritual power poured into his feet, Ning Tao's legs bent at the same time, and then kicked violently in the void, and his body suddenly had an upward movement. Although it was not able to escape gravity, the speed of its fall slowed down a little. Then he kicked again, slowed down, and kicked again......

There was a ladder under his feet, and when he reached the seventh step, Ning Tao's body was in the void for a while. It was only a little over a second, but it was enough time for him to open his little medicine box.

After that, his body fell violently again.

Ning Tao reached into the small medicine box, took the medicine collection rope that lived inside, poured spiritual power into it, and waved his hand to the right side of his body.

The medicine collection rope is the magic weapon of the Tianwai Clinic, it is just a rope in the hands of others, but in Ning Tao's hands, it is a magical magic weapon.

Call!

The spiritual power was activated, and one end of the medicine collection rope flew out like a spear, constantly extending. Ning Tao's arm quickly twisted twice, wrapping the rope around his arm. He had just finished doing this when there was a vibration at the other end of the rope. He couldn't see it, but he knew that it was the hardened rope that had dug into the rock!

A second later, his body was suddenly pulled off the trajectory of the straight fall, and slammed into a cliff. The right arm wrapped around the rope was almost dislocated under the pull, the fabric of the clothes was instantly shredded, and the skin on the arm was also worn off. A hot tingling sensation spread from his arm to his body, and he bent his legs in excruciating pain. At that moment, his legs slammed into a mountain, and his body slammed into it.

The rope of the herb had fallen off, and his spiritual power could not maintain its hard end for long. However, there is no need for it. Just as the rope fell off and his body fell again, his left hand had already grabbed the edge of a rock and fixed it on the mountain.

A rock fell from under his feet and fell, and after a few seconds he heard a dull thud.

It's almost the end.

Ning Tao breathed a long sigh of relief, he was not in a hurry to go down on the mountain, but took a rest, and ran special spiritual power to treat the injury on his right arm. The pain in his right arm quickly disappeared and he regained some mobility. After that, he used his right hand and mouth to tie a noose around the rope and put it on the edge of the rock that his left hand was clasping. Then, he grabbed the rope and slid down.

With his feet touching the ground, Ning Tao's whole body relaxed, his body and soul seemed to be emptied in an instant, he sat on the ground with his butt, and then lay down.

"If those wild people attack me again, I won't show mercy anymore!" Ning Tao looked up at the oval sky above his head, thinking back to the experience just now, his heart palpitated. On flat ground, he can also open the blood lock to escape, but in the process of falling rapidly, even if he opens the blood lock, he can't get in, because he opened the blood lock a second ago, and a second later he has already fallen. This time, if he hadn't made sufficient preparations in advance and brought the medicine rope, he would really be buried in this dark cave.

After resting for a few minutes, Ning Tao got up from the ground, he grabbed the end of the medicine collection rope, poured spiritual power into it, and shook it, and the medicine collection rope quickly recovered and returned to his hands. He put the rope into the small medicine box and closed the lid.

Looking down from the forest with a little light just now, I couldn't see my fingers here, but this place was not as dark as I imagined, there was no thick fog overhead, and there was a faint light shining down, and I could vaguely see the blurred scenery around me. The few minutes of rest had allowed his eyes to adjust to the darkness of the place, and he could see farther, vaguely seeing stones three meters away.

Ning Tao saw a lot of stones, oval-shaped, like eggs stretching out into the darkness. He listened intently, and could faintly hear the sound of running water, but it was far from the waterfall he had imagined.

"Could it be that this cave is in the shape of an urn, with a large bottom under the mouth, and that small waterfall that I saw above is flowing against the rocks, far away from me?" Ning Tao guessed in his heart, and he walked towards the oval stone closest to him.

One-third of the oval-shaped stone is buried in the earth, and two-thirds of the exposed stone is about one meter high. Ning Tao took out his mobile phone, woke up the screen, and took advantage of the low light of the screen. He soon discovered that the oval-shaped stone was not natural, had been polished, and had some unreadable words, or runes, on it.

Ning Tao took a picture of the stone, and then walked towards another oval stone. When he went to the second stone and looked at it, he was surprised to find that the second stone was exactly the same as the first stone in terms of height, diameter, and even polish, but the words or runes carved on it were different.

After taking pictures, Ning Tao continued to walk forward.

The oval stones were left behind him, and his heart became more and more surprised and confused. Every oval stone he had seen was the same size, material, and even polished. Ma Tongtong said that the civilization of the Yinyue people disappeared during the Warring States Period, and the tools used by people at that time were still fragile bronzes, and there were no tools to carve and polish such stone eggs, let alone create so many stone eggs of the same size.

"Is it industrial production? If so, then hell is it. During the Warring States Period, if the Yinyue people had such productivity, it would not be difficult for them to conquer this world at all, right?" Ning Tao couldn't help but guess in his heart.

As he walked on, there was no sound around him, only the sound of his footsteps in the distance, but no echo came back. Stone after stone appeared in his sight, and he was left behind him, but he had lost interest in taking pictures. For a while, he suddenly remembered something, he stopped, opened the small medicine box, took out the earth-seeking inkstone, and poured thirty milliliters of ink into the earth-seeking inkstone. The ink pointed in one direction to the side, and he changed direction and continued on his way.

He hadn't gone far before a vague silhouette appeared in front of him, boxy.

"Town, is it a city with a cloudy moon?" Ning Tao became excited in his heart, and walked over with faster steps. As he walked, he awakened his eyes and nose to see and smell, and activated his phone's flashlight function.

It was indeed a town, and although the beam of the mobile phone flashlight could only reach a part of it, it could be judged by the outline of its appearance, and its scale was not large, about the same as that of a township. It was surrounded by walls, but it was not very high, only five or six meters. The buildings behind the walls can be vaguely judged to be rectangular buildings, a bit like miniature modern buildings.

The ripples of ink in the inkstone continue to point to the town.

Ning Tao walked over quickly and came to a city gate. The city gates have collapsed, and the buildings behind the gates have collapsed quite a bit. There were a few plants on the streets and buildings that didn't need light to grow, and they looked like bryophytes, but they weren't the kind he picked in the forest above.

Ning Tao stepped through the collapsed city gate and walked forward in the direction guided by the earth-seeking inkstone.

The streets are paved with stone slabs, and in some places there are even dents that people have stepped on, as well as the huge footprints of the Shennongjia savages. Some of the cuboids had their doors open, but there were no furniture, no pottery, nothing in the room. It feels like all the people and their belongings in this place have suddenly disappeared and gone to another plane, so that only the stone city remains.

Suddenly, the beam of the phone's flashlight hit a strange crack. It is about a meter wide and a meter deep, extending tens of meters forward. Its edges were full of jagged openings, some of the stone cracked, some shattered, and some had obvious burn marks.

Ning Tao walked forward along the crack for dozens of meters, and when he reached the corner of the street, his feet could no longer move.

At the corner of the street stood a three-storey stone building, made of large sturdy stones, but it was such a stone tower comparable to a European castle, and the crack actually split it alive, leaving a one-meter-wide crack in the middle of it!

Ning Tao was stunned for a long time before he came back to his senses, and said to himself: "It is impossible for lightning to fall in this place, but if it is not lightning, who is the split?"

He couldn't help but look back at the crack in the street for dozens of meters, and was shocked in his heart, if it was really split by someone, how strong that person must be!

Could it be an immortal?
