Ling Yun rushed out of the stone gate first, he stood at the door of the stone room like a god, using two minds, wielding the dragon scale knife and dragon pattern sword in his hand impenetrable, and the vampire bats that rushed over were cut to the ground by him like chopping melons and vegetables, and soon piled up a black mountain of meat in front of him.

Not to mention vampire bats, with Lingyun's sword in hand, not even a single mosquito can fly in!

The night pearl in Ling Yun's chest pocket bloomed with a faint brilliance, which allowed him to easily see the surrounding situation clearly, in the distance, five or six corpses were lying on the cold rocks, but their bodies were crawling with black vampire bats, and in just a while, only the skeleton was left after being eaten.

Ling Yun shook his head, secretly screaming that it was a pity, and after Xiao Bai came out, he raised his foot and kicked back, and his left foot kicked the stone button as if he had an eye, closing the stone door again.

The cave next to the stone chamber was only twenty meters away from Ling Yun, and he brandished his sword and walked towards the cave in a leisurely manner, killing vampire bats all the way to the cave.

The vampire bats were in hot pursuit, and Ling Yun was not relentless, still killing as he walked, while carefully examining the situation in this cave.

The entrance to the cave was very large, but Ling Yun found that it was getting narrower and narrower, and the yin aura here had reached a very heavy level, and after walking a hundred steps inside, the vampire bats never followed, and all retreated.

Ling Yun stopped, glanced back, and knew that this place was infinitely close to the eye of the Yin Array, and even those bats living in the darkness did not dare to come over.

He raised the dragon scale knife and the dragon pattern sword in front of him at the same time, and found that the blade was still pitch black, the sword body was still snowy, and there was not even a trace of blood, and his heart was even more satisfied.

"Killing people doesn't get bloody!" Ling Yun smiled, put away the dragon pattern sword, and continued to march towards the formation eye with the dragon scale knife in one hand.

There were no more forks in the road on either side of the cave, and Ling Yun did not encounter any danger except for the increasingly thick yin aura that could not be dissolved.

This cave was inclined downward, and it was getting steeper and steeper, and Ling Yun walked for more than ten minutes, feeling that he had descended another fifty or sixty meters.

Fortunately, he now has a night pearl to illuminate, and his eyes can see far away, which does not affect his judgment and actions.

"That's not right, if my calculation is correct, the place directly above here should be the place where the Earth Yin Grass grows, but why isn't this the Eye of the Yin Array?"

Ling Yun stood in the cave, secretly frowning and pondering, although the yin and evil qi here was enough and it was already relatively refined, Ling Yun still didn't want to cultivate here, because this place was not a real formation yet.

"Let's go down and take a look!" Ling Yun put away the dragon scale knife and took out the human emperor pen again, because the cave in front of him was already too narrow to wield the knife.

Ling Yun continued to walk down with Xiao Bai, and soon he heard a deafening rumbling sound that shook the entire cave slightly.

"It's the underground river! it turns out it's flowing here!" Ling Yun immediately quickened his pace, and as the sound of the water became louder and louder, the yin aura began to become scarce again.

The temperature in the cave began to rise again, and fifty meters down, the cave began to become damp again, and the water began to drip again.

"It's really weird, do you really want to go back and cultivate there?" I'm not reconciled......" Ling Yun was slightly angry, but since he had walked down, he decided to go over and take a look.

Continuing down, after about half an hour, the cave was no longer steep, but the entire cave had become extremely narrow, and Ling Yun could not move forward when he bent over, so he could only crawl forward on the wet rock.

Ling Yun is the kind of person who doesn't give up until he reaches his goal, he doesn't believe that he will make a mistake in judgment, if the Yin Yang Lock Dragon Great Array doesn't have a real formation eye, it is absolutely impossible, but as long as there is, he must find it!

A man and a fox crawled with difficulty in the narrow cave, and the majestic sound of the water became more and more earth-shattering, Ling Yun's heart moved slightly, and he accelerated the speed of crawling again.

Fortunately, the further forward the cave was, it began to become more spacious again, and in the end, Ling Yun could already stand up and walk forward again, he no longer kept, his body was more than ten meters in a flash, and it didn't take a minute to reach the end of the cave!

This section of the road was the longest section, and it took Ling Yun at least more than an hour to get here when he came out of the stone chamber!

"Hey! That's right!" Ling Yun came to the end of the cave to take a look, only to see that outside the cave was a bottomless mountain stream, and the underground river poured down a hundred meters above the cave, forming a huge waterfall a hundred meters wide, and the sound of rushing water was several times stronger than when he was at the bottom of the sinkhole!

"We've come down at least another hundred meters!" Ling Yun looked up and knew that this was the real belly of Nancui Peak, but he didn't expect that there was a bigger sinkhole here!

Ling Yun raised his hand to pick up a palm-sized stone, then wrapped a fire talisman around the stone, shouted pro, and then threw it down.

"It turned out to be only more than thirty meters deep, so I said, if it is really bottomless, how can those water monsters come up!"

Ling Yun smiled slightly, he held the human emperor pen in his right hand, picked up Xiaobai with his left hand, and jumped lightly to a protruding rock ten meters below, and so three times, he came to the bottom.

This is a huge lake, or a huge deep pool, and I don't know how deep it is after the impact of the 100-meter-wide waterfall for many years.

"I see!" Ling Yun took a look at the environment of this mountain stream, and immediately found that behind the huge waterfall, there was actually a natural cave.

If it is not bad as expected, the Yin Array Eye of the Yin Yang Locking Dragon Great Array should be in that cave!

Ling Yun smiled slightly, picked up Xiaobai again, he didn't dare to be careless, holding the human emperor pen in his hand, he flew up the slippery cliff, inserted the human emperor pen into the rock of the cliff and borrowed his strength repeatedly, and soon came to the cave behind the waterfall.

"It's so cold!"

There is a cave inside the cave, and the outside is still unusually hot, as soon as this cave enters, Ling Yun actually feels cold and biting.

There was no doubt that this was caused by the yin aura emanating from the eyes of the Yin Array, and Ling Yun couldn't help but admire the peerless figure who created the Yin Yang Locking Dragon Array.

This cave is twenty meters high in a huge pool, and after Ling Yun came in, he no longer cherished his fire talisman, and he directly used the fire talisman as a flare.

The cave is large enough to accommodate two wagons running side by side, and it is inclined upwards.

Ling Yunxin said that he didn't know if there would be a yin spirit here, he took out the dragon scale knife again, but he still held the human emperor pen in his right hand, which was used to deal with emergencies.

He took out a few more Night Pearls and stuffed them into his pocket, and with the light of the Night Pearls, he galloped towards the depths of the cave.

The Yin Array's Array Eye was vertically upward, and Ling Yun had to go back to the place where the Yin Evil Qi was the strongest just now, and he knew that it was the Array Eye.

Seeing that he was about to be able to cultivate the Yin and Yang Technique, and then he could break through the fourth layer of refining his body in an instant, Ling Yun's heart began to be really excited, the light in his eyes flickered, and his feet became faster and faster, and in the end, it was simply a lightning speed.

In about ten minutes, the yin and evil qi in front of him has been so strong that it can't be dissolved, and the temperature here is also unusually low, at least more than ten degrees below zero, Ling Yun doesn't think so, but Xiaobai can't bear it anymore.

Ling Yun stopped, smiled at Xiao Bai and pointed, "This place is beneficial to our cultivation, you can take the opportunity to practice your exercises to fight against the cold here." ”

Xiao Bai nodded, and began to operate his own cultivation method, and sure enough, he felt less cold.

Ling Yun still hadn't absorbed the yin qi here, he knew that fifty meters in front of him was the eye of the formation, so he wasn't in a hurry at all.

Ling Yun slowed down, tightly held the Dragon Scale Knife and the Human Emperor Pen, and walked towards the front step by step, and after more than ten meters, his eyes suddenly opened up, and he walked into a huge pot-shaped cave again!

The temperature dropped a lot in an instant, and at the same time, the yin and evil qi skyrocketed, extremely pure, Ling Yun completely let go of the pores of his whole body, and finally began to run with all his strength to start a yin and yang technique, and frantically absorbed this incomparably pure yin and evil qi!

It's a pity that he didn't find the Yin Spirit, but at this time, it doesn't matter whether there is a Yin Spirit or not, this is the Yin Yang Lock Dragon Great Array Yin Array, which is even better than the Yin Qi of the Yin Spirit.

Ling Yun unfolded the Phantom Fish Dragon Step, and instantly came to the center of the vast cave, where there was a dark deep pool the size of a wellhead, and all the yin and evil qi came out of this deep pool.

Lingyun told Xiao Bai not to approach, only let him wait for him in the distance, and then sat down cross-legged next to the deep pool.

Ling Yun silently used the Yin and Yang Technique, absorbing the pure Yin and Yang Qi around his body with all his might, and began to cultivate the Yin and Yang Technique.

The violent and pure yin qi frantically poured into Ling Yun's body, and then through Ling Yun's twelve canons, it began to converge towards his dantian.

One hour, two hours, three hours......

After a full nine hours, Ling Yun felt that the Yin Qi had almost been absorbed, and after it was already on par with the Yang Qi accumulated in his body, Ling Yun began to operate the aura in the dantian.

The yang and yin qi within the Lingyun dantian were distinct at first, but soon, under the effect of the yin and yang technique, they penetrated and entwined with each other, and finally turned into chaos.

The opportunity was not to be missed, Ling Yun urged a yin and yang technique with all his strength to make the yin and yang qi in the dantian rotate rapidly, and the two diametrically opposed breaths gradually turned into a cyclone, and they rotated faster and faster!

"It's about to be done!" When Ling Yun was overjoyed, he was about to complete the last step, but at this moment, Ling Yun felt the immortal aura in his dantian again, and began to riot!

Black and white immortal qi poured out from Ling Yun's dantian and began to frantically devour the yin and yang qi in his body!

"I'm rubbing, it's a big trouble now!" Ling Yun was horrified!
