When you enter it, you will be submerged in a blue fog below your knees, and this stone cave will cover an area of hundreds of square meters, and people will feel like stepping into a sea of blue clouds inside.

The two of them walked towards a broken stone door in front of them, which was mostly collapsed, and it was clear what they had stepped on under their feet, and the sound of "click" shattering kept sounding.

Xu Ning's curiosity rose, he bent down and touched it with his hand, grabbed a round hard object in his hand, picked it up and looked at it, and almost called out Yan Bing beside him, and hurriedly covered his mouth with his hand.

It turned out that Xu Ning was holding a human skull in his hand, and the white bones were mutilated.

Xu Ning hurriedly threw it away and continued to walk forward, stepping on the bones without listening to his feet, presumably there had been an extremely tragic battle here, and the corpses were piled up on the ground.

When I arrived at this fallen stone gate, it turned out that there was a corridor behind the stone gate, and the fog gradually thinned, so that you could see the situation under your feet, and it was also the bones of a place. I don't know how many years these people have been dead, they will be shattered at the slightest touch, and there are all kinds of weapons on the ground, these weapons are extremely well preserved, Xu Ning picked up a handful and held it in his hand, it was quite sharp.

"Be careful, don't disturb the dead." Yan Bing reminded in a whisper behind him, "These corpses must be the ancestors of our ancient clan, and I don't know if they are the generation that the patriarch grandfather said about cannibalism." ”

Finally walked out of the Yongdao, the situation in front of it was slightly better, after all, there were fewer bones under the feet, this distance was connected to the stone cave and the Yongdao, and there was no other scene, until the two entered a stone cave with an altar in the middle.

This altar was no different from the one in front, Yan Bing recited the mysterious incantation as he drew a gourd, and sure enough, the white light of those runes shone out, gathering around the two of them, forming a pillar of light to lift the two of them up.

Xu Ning looked up, it was still dark, until a bright spot appeared, and in an instant, the bright light in front of him was dazzling, like day.

The two of them were sent from one altar to another, and the place where they were standing now turned out to be an empty square!

The square is paved with smooth cyan stone slabs, quite smooth and neatly arranged, and even decorated with another red stone around the square.

There are several tall carved stone pillars standing inside, and the pattern is clearly the pattern of colorful fairy orchid flowers. The two looked up, and there was no trace of sunlight in the sky, and then they remembered that it was night at this moment, but the sky was white, and there was no shadow of the moon.

Xu Ning looked at Yan Bing and found that she was also at a loss. Just as he was about to step down from the altar standing in the middle of the square, suddenly the light around him disappeared, and it was dark again.

"It turned out to be the bright light emitted by this pillar of light." Xu Ning said to himself, and shook his head again, "It may also be an illusion." ”

"When you step out of this altar, you will enter the center of the underground ancient city." Yan Bing reminded Xu Ning, took out the blue bottle again, dipped some in a handkerchief, and wiped it on Xu Ning's nose.

Xu Ning understood, inhaled hard, and suddenly felt refreshed and breathing smoothly.

Yan Bing himself sucked it for a while, and then walked off the altar and walked outside.

The images in the distance were not clear, and the black things looked like valleys and forests, or they could be nothing but a cloud of mist. The place where they stood was clearly the center of a bustling town, and there were collapsed houses on both sides, forming piles of rubble, like huge tombs, silent in the darkness.

Yan Bing led the way in front, groping forward with the memory of the drawings, Xu Ning was secretly on guard, and any sound around him could not escape his ears. Yan Bing took Xu Ning to walk around this ruined town, going around and around, and couldn't find a target for half a day.

Xu Ning didn't dare to disturb her mind, just followed behind, and finally stopped on a cobblestone road, Yan Bing, and said, "This cobblestone road leads to the palace, we just need to go forward." ”

Xu Ning didn't understand anything, thinking that the palace was the most important place, and the soul searching furnace must be in the palace.

The cobblestone path stretched forward, hidden in the darkness. The surrounding buildings are taller, the remnants of the rock walls are chaotic and intertwined, and the silence is terrifying, the silence is suffocating, and even the subtle footsteps of the two people have become clearly audible.

Xu Ning looked forward and looked carefully, and suddenly his face froze, and he grabbed Yan Bing.

As soon as Yan Bing was about to speak, Xu Ning gently covered his mouth, and his two big eyes flashed, and his eyes were full of doubts.

There was a faint roar in the darkness in the distance, what seemed to be a low muffled thunder. The two of them just listened quietly and waited, not daring to move a step.

The thunderous sound grew clearer and clearer, and gradually became noisy, making a crackling sound. Suddenly, I found a huge black cloud faintly floating in the middle of the air in the distance, and after a while, the whistling rumbling sound was close to my ears, and a fishy smell wafted over, which made people sick.

When the dark clouds drifted closer, the two of them realized that this was not a cloud at all!

It was too late to hide, and the dark clouds suddenly dispersed, turning into countless monsters with cats and bird bodies, each with sharp teeth and big mouths, hideous and terrifying, and swooped towards the two of them.

Xu Ning did not retreat but advanced, and slammed out a palm into the air, and the qi rushed out of him, and the birds in the air were suddenly scattered, and there were constantly terrible chirps, and some were directly shocked to death and fell to the ground.

But in just a moment, the flock of birds continued to gather here and rushed towards it with their terrifying mouths open.

Xu Ning kept clapping his high-fives into the air, but these black strange birds with cats were obviously afraid and guarded against his attack, and they all scattered together to dodge before the palm wind approached, and the speed was as fast as the wind.

Yan Bing was anxious and frightened behind him, holding a bow and arrow in his hand but unable to shoot it, there were too many strange birds in the air, densely packed and countless, her bow and arrow could not be used at all, she could only watch and be anxious.

Xu Ning's face also sank, and in the long run, even if he consumed his entire body, he couldn't kill it all. The true qi in his body was agitated, but he couldn't release the Eighteen Demon Slayer Locks for a long time, or because these strange birds couldn't kill, and the attack range of the Demon Slaying Lock was also limited, and it required the most internal force to consume, and in the face of this kind of cat-headed monster bird with a dodge speed like black lightning, it was really beyond the reach of the chain length.

The flock of strange birds attacked the two on the ground again, making a loud noise and a stronger fishy smell.

Xu Ning still used a powerful palm wind to form a wall of qi in front of him, and when the evil bird blocked back, several more were hit by the qi and fell down, struggling on the ground for a moment and stiffening to death.

"Ahh

Yan Bing behind him let out a panicked scream, Xu Ning hurriedly looked back, only to see that the two strange birds were killed by her blow with a horned bow, and a few drops of black dirty blood were also splashed on her face and clothes, making her disgusted.

Sure enough, the flock of birds in the sky no longer attacked Xu Ning from one direction, and spread out in the air, enveloping them from all directions. The number is also getting more and more, densely packed like a huge black curtain.

Xu Ning looked around left and right, but here are all ruins and broken walls that have been dumped into stone piles, and there is no place to hide, it is really urgent, if he is attacked by evil birds, look at the sharp teeth in the bloody mouth, I am afraid that even the bones will be gone.

Yan Bing, who is usually Zhong Lingyuxiu, was also frightened by the bloodthirsty bird flock on her head at this moment, and her hands tightly grasped the horn bow, using it as a bow and arrow, and the sneak attack with the two cat-headed evil birds just now had made her very wolfish and confused, and a few strands of hair fell out of the hairband, messily sticking to her sweaty cheeks. She only bent down and raised her head to be on guard, but her body kept retreating, hitting Xu Ning from time to time.

"Why don't you try the talisman seal that Grandpa Patriarch gave you?" Xu Ning didn't take an inch away from her, looking up at the flock of birds gathered in the sky above, while reminding her.

Yan Bing came to his senses and hurriedly took out two stacks of talismans from his arms, and at this moment, there was a sharp hissing in the air, and the birds attacked again.

Her little hand shook, and the talisman seal in her hand fell to the ground, instinctively grabbing the horn bow to protect her body.

The qi in Xu Ning's body was running violently, his feet were a little, his body jumped straight up, and the eighteen demon slaying chains burst out from his palm.

The Black Snake Chain Technique swirled into a black vortex in the air, forming an impermeable and indestructible shield above the two of their heads, and the black mist was shrouded. The cat-headed monster birds flying in front of them were swept into it one by one, making a terrible strange cry, and they disappeared in an instant, and many of them were shocked and flew out, hitting the stone pile, and they struggled desperately, constantly wailing.

The flock of birds was scattered and flew back into the air, still unable to leave, only to continue to gather overhead, like a shadow.

Xu Ning retracted the chain, his heart was a little calm, and he saw Yan Bing rushing to the gravel pile next to the road, raising the horn bow in his hand, and constantly hitting the injured and struggling cat-headed monster birds, and scolded while hitting his mouth: "I'll let you fly, I'll let you fly again......"

"Bing'er, what are you doing? Hurry up and try the power of the sigil! Xu Ning stopped.

Although the continuous attacks of the Black Chain Technique were used to knock down a lot of evil birds just now, looking at the black wings in the sky, I am afraid that even if I exhaust my internal strength, I can't kill a tenth of it, but I just suspend the form.

Yan Bing was asked by his shout, and the horned bow held in mid-air was finally retracted, and he hurriedly picked up the talisman seal from the ground again, groaned slightly, took out a purple talisman seal, and said: "This is the 'Purple Light Night Talisman', I'm going to try it now." ”

Xu Ning watched her staring at the mysterious words on the soul talisman, and between her lips, a spell came out of her mouth.

These are all mysterious ancient languages, Xu Ning can't understand a word at all, and after listening to Yan Bing read it for a long time, he didn't seem to have any reaction.

Before he was wondering, there was a thunderous explosion in the air, Xu Ning suddenly raised his head, and countless pitch-black wings shot in his eyes, Xu Ning shouted at Yan Bing: "You may have recited the wrong spell." Hold your mind and read it again! ”

As soon as the words fell, the person had already jumped up, and once again sacrificed the eighteen demon destroying chains, and the vitality in the dantian guò meridians erupted, and the black chains and black birds were entangled together, and the strange cries came and went, and they were extremely tragic.

This time, the flock of birds began to sprint from all directions like raindrops, and the wind and rain were about to break through the blockade of the chains, and the demon slaying locks continued to devour black monsters, black smoke steamed, and the fire flickered.

The flock of birds attacked one after another, and without flinching, scattered black feathers falling from mid-air, as if a black snow was falling on this ancient street.

This black snow was blowing one after another, and at this moment, a chill suddenly rose in Xu Ning's heart
