As Yun Aotian gradually stepped into the depths below the main hall through one secret passage after another, Feng Ren had a feeling that the secrecy here and the degree of going deep into the ground could not be compared to the Cangyu Sect, not to mention the Annihilation Pavilion.

And in the process of going deeper and deeper into the ground step by step, a strange feeling invisibly poured into his body, and in the faint coldness, there seemed to be a special fluctuation, and there was a vague sense of déjà vu.

The journey along the way was too silent and boring, and Feng Ren finally couldn't help but ask: "Sect Master Yun, I don't know something, since the Heavenly Scar Sect has such a secret passage, why don't all the people retreat here to fortify, but instead have to lay a defense line outside?"

"The terrain is narrow, and it's really good for arming. But if we fail, we will be able to seal our own retreat, and there is nowhere to escape. And, most importantly, I don't dare bet and try to fight the undead in a place like this...... In all likelihood, they will look forward to this being a battlefield even more. ”

When the words fell, Yun Aotian also stopped, and at this moment what appeared in front of him was a closed door, and the simple door frame was engraved with lines similar to some ancient characters, but due to the age, it was already blurred.

Looking up at the lines on the door, Feng Ren felt inexplicable in his heart, although he couldn't recognize what the vague words on it were, but there was an instinctive judgment that he didn't know where it came from.

These texts...... It should be the text of the elves.

Catching a glimpse of Feng Ren's surprised expression, Yun Aotian naturally didn't know the reason for the real surprise in his heart, he only thought that he was amazed by the last gate itself, and couldn't help but explain: "Actually, the real reason why my Heavenly Scar Sect was able to change from a small force to a giant in the Southern Continent is here. In fact, the ancestors who established the Heavenly Scar Sect didn't know that there was such a secret buried under the location they chose to build the Sect, to be precise, they didn't know where the special aura floating in this area came from, they just felt that this place was more intense, so they chose this place to establish the Heavenly Scar Sect. ”

"I heard that the real rise of the Heavenly Scar Sect was because of you, Sect Master Yun, that is, because you discovered this secret, right?" Feng Ren smiled and looked at Yun Aotian with a little deep meaning.

"No, that's not what I found here. It was discovered here several generations ago. It's just that the ancestors couldn't open the door, but after more than two hundred years of continuous attempts, in the fifth year after I became the sect master, I was lucky enough to break the last seal and open the door. At that moment, everyone present was shocked. ”

When the words fell, Yun Aotian also waved his hand, and the invisible fluctuations instantly merged into the gate.

At that moment, the lines on the door gradually flickered and lit up, and a little pale silver light spread to every moment on the entire door, and with a dull sound, the crack in the door cracked, and the quaint door slowly opened by itself.

At that moment, a biting cold seeped out from the crack in the door, and although the oncoming cold wind was slight, even the corners of his clothes were not raised, but the amazing cold contained in it made him frown, and he instinctively used the fire attribute energy in his body to block it. If he had been slow at all, he had no doubt that his bloodlines might have been frozen into ice slag in that deep cold.

"What kind of fluctuation is this, so cold?"

He was shocked in his heart, and turned his head to look at Yun Aotian beside him, however, what he saw was the other party's puzzled expression.

"Ah, is it that cold? Maybe it's a little cold, but your reaction is too big, right?" Yun Aotian was obviously a little puzzled, looking at him as if he was very casual, and he was not affected by the terrifying deep cold before.

Seeing this, Feng Ren was even more surprised in his heart, Yun Aotian's cultivation was far inferior to him, even if he had prepared in advance, he definitely shouldn't behave so freely. Based on his previous feelings, that Sen Leng was not something below the Dao level that could be contended. What's more, the current Yun Aotian is injured.

Could it be ...... The deep cold breeze just now, just towards him alone?

At this point, there is no point in leaving where you are and guessing blindly, since the door is open, it is the most straightforward thing to go in and see what is going on.

The thought in his heart was determined, and Feng Ren did not wait for Yun Aotian to lead the way, and took the lead in stepping into the door. However, there was no trace of cold wind continuing to blow out, but there was a little chill in the air itself.

Inside, the light wasn't bright, but it wasn't dim either, and with the help of a pale blue ripple halo that he didn't know where it came from, he looked up and saw the only thing standing in the crypt.

At that moment, the shock in my heart was indescribable.

I saw that the crystal ice crystals blocked the other end of the cave that I don't know how deep it was, and a trace of cold overflowed from the surface of its whole body. However, these words alone were not enough to shock him like that, and the real source of surprise was not the large ice crystal that could be called an iceberg, but what was frozen inside.

It was a huge skeleton, nearly 100 meters high, the whole body was shiny and smooth, the quality was like high-grade white jade, from the structural point of view, it seemed to be a rare dragon family, with two feet and four claws, and eight wings on its back. Although only bones remained, they were just frozen and stood there, and a faint power of oppression had quietly permeated invisibly, directly forcing the pale golden light in Feng Ren's eyes to flash, and the slender dragon shadow couldn't help but appear directly.

"What kind of dragon is this?"

The surprise in his heart continued to magnify, thinking that it would be good if he had brought Feng Wudao with him, maybe he would be able to know the true identity of the skeleton in front of him.

Yun Aotian in the back shook his head and said, "I don't know, presumably it must have been a peerless beast when it was alive, but for some reason there are only bones left, and it is still frozen here." Judging by the fragmented writing on the door, it must be that some civilized race could do that...... I've also looked up some information over the years, but none of the known dragon beasts I've learned have been able to match this skeleton, not even anything more similar. There is one feature of it that is too peculiar. ”

With that, he raised his hand and pointed in the direction of the head of the keel.

As soon as his heart moved, the wind tenaciously floated into the air, and the distance of 100 meters was only a blink of an eye for him. When his body was on par with the dragon bone, he also immediately understood what Yun Aotian was referring to, and his heart was shocked again.

Indeed, such dragons are unheard of and unseen. And just looking at it from below, you can't find it at all.

In the middle of the huge keel, there is a circular cavity that almost occupies half of its face, and if you think about it, it is not difficult to conclude that it is its eyes. There is only one eye, and it is surprisingly large.

Standing in front of that hollow, Feng Ren trance had a kind of self standing on the entrance of an endless abyss, and if he was not careful, he was likely to be swallowed by the ghostly darkness.

With a secret sigh in his heart, he turned around and was about to fall, but at that moment, all of a sudden, the chill that had been felt when the door was opened before came back to his body, and the cold stinging pain almost froze all over his body.

However, that strange feeling only lasted for a blink of an eye, and Feng Ren looked back again in shock, looking back at the keel imprisoned in the ice again, and his gaze once again met the empty eye socket that was enough to devour himself at will.

In an instant, he had an illusion, as if the keel had moved, and a slight light flashed in the hollow eye sockets. However, as he concentrated on looking again, everything stood still, and all movements froze in time with the cold ice crystals.

What was the feeling just now?

Feng Ren had one thing in his heart to confirm, it was definitely not his illusion just now, from the moment the door opened, he felt a trace of discomfort all over his body, not only the piercing chill in the air, it was a sense of isolation from the depths of his soul, as if he had been secretly watching his every move by someone.

And now it seems that the only possibility is the dragon bone in front of him, a strange dragon clan with a height of more than 100 meters and an unknown origin, and only one eye.

Other words...... It's not completely dead yet?

Looking up at Feng Ren above, although he couldn't see the puzzled expression of the other party's face turned sideways, Yun Aotian obviously guessed a little, and said in a loud voice: "I guess you have also found it, right? This skeleton is not dead, it seems that there is some kind of special aura, which is transmitting something to the outside world, maybe this is the reason why it is still frozen and imprisoned here in this state." ”

With a secret sigh, Feng Ren fell to his side and asked, "You seem to have said just now that the rise of the Heavenly Scar Sect is because of it?"

"Not bad. Yun Aotian nodded and explained, "Cultivating under the cold qi that permeates it, the tempering of muscles and bones and the condensation of strength in the body have been strengthened. As a result, the entire Heavenly Scar Sect was shrouded in the aura it exuded, and all the disciples were able to gain gains. But more importantly...... Hmph, presumably, you should know what the most secret martial arts of my Heavenly Scar Sect is, right?"

Feng Ren didn't think about it, and replied directly: "Anticipate the enemy's first opportunity, Zero Eye." ”

Yun Aotian replied: "Yes, it's the Eye of Zero. However, there is actually something wrong with the rumors on Nanda Road. It wasn't the previous sect masters who really held the Eye of Zero, but only me and Qingkong. In fact, the previous Sect Master was only able to occasionally provoke a quicker reaction in battle, which was far from the real Eye Zero. I don't know, can you guess, and why?"

Feng Ren was startled, and looked back at the frozen keel behind him, and there was a faint tremor in his voice: "The highest mystery of the Heavenly Scar Sect, the Eye of Zero." The attributes are unknown, the grade is unknown, and the cultivation method is unknown...... That's because Zero Eye doesn't have a substantive inheritance practice at all, but you ...... What did you learn from it?"

With a snap of his fingers, Yun Aotian exclaimed, "Exactly right. It had not been discovered here before, and the sect masters of the past dynasties relied on their own cultivation to be far from the rest of the disciples and elders, and they barely touched the prototype of the Zero Eye under the faint fluctuations. And when I found it, the moment I saw the only eye to be exact, I already knew what the weird feeling I had felt before. It is the source of the Zero Eye. However, we don't have a specific cultivation method, we just sit here and feel the cultivation, and it seems that we can invisibly get more dark fluctuations coming out of its body. I'm afraid that's why Zero Eye's activation depends not on me, but on its own at a critical moment. ”

Hearing this, Feng Ren glanced at the keel again, and smiled a little meaningfully: "Really, then, I'm a little interested in trying." ”
