Lin Dong didn't stay in the ruins of the Qianyun Sect for too long, and after seeing Mo Ling and the three of them smoothly enter the main hall to accept the inheritance, he also set off again and left this ancient Guanglu field directly.

The light curtain that shrouded the ruins was obviously difficult to get in and out, so Lin Dong didn't bother to leave smoothly, and when he came out of the light curtain, at this time, almost all the people around the Hanging Island had dispersed, and after a little look, he took Xiao Yan and rushed directly to the depths of the ancient vault.

Of course, entering this ruin, Lin Dong was not without gain, the stone tablet recorded a lot of information about this ancient treasure, and the information was obviously much more complete than what Lin Dong got from the skeleton, and even some routes to the depths were known to him.

With the ultimate goal, Lin Dong didn't have the mind to go around, although there may be a lot of sect inheritance in this ancient secret treasure, what he wanted was not an ordinary inheritance.

If you don't do it, once you do it, it must be the best, and obviously, in this ancient secret treasure, the most powerful inheritance should belong to the four Xuanzong, they are the controllers of this Tiangang Alliance, and that kind of inheritance must not be an ordinary thing.

Of course, Lin Dong also knew that he would not be the only one who took a fancy to the inheritance of the Four Xuanzongs, and even Liu Bai and the characters all had thoughts about the Four Xuanzongs, so it was not a simple matter to come out on top from the competition.

After all, the dynasties and powerhouses that are qualified and ambitious to fight above the Four Xuanzong will inevitably surpass the Demon Rock Dynasty and Shi Kun, and these people are extremely tricky......

"Four Xuanzong, no matter what, there must be a sect inheritance in my hands, so it's worth the trip." Lin Dong raised his head, looked at the distance of the gray space, and muttered to himself.

In the following hurry, Lin Dong did not stop because of anything, and even if there were rumors of sect relics in some places, he was not the slightest bit moved, the direction remained unchanged, and he went straight to the depths of the secret Jane.

And under his rapid hurry, he could also feel that the Yuan Force between the surrounding heaven and earth seemed to have become faintly thicker, and the already broken space showed signs of being broken.

However, Lin Dong also understood that this and the changes in the environment also showed that he was gradually approaching the depths of the ancient vaults, and these places were not dared to enter by ordinary dynasties and strong people.

And as he went deeper into the ancient vault, the lively scene that Lin Dong had seen before him became rare here, only occasionally, he could see some figures with a strong aura rushing by, and that and the breath had actually reached the point of one-yuan nirvana.

Xing Ran, the dynasty and the strong people who can come here are all the leaders in the northwest region.

In this and hurry, about an hour or so later, Lin Dong suddenly noticed that the temperature of the air around him seemed to be rising, and his eyes immediately narrowed, as if he thought of something, but there was a flash of joy in his eyes.

Joy flashed in his eyes, Lin Dong raised his head, looking into the distance, the space there suddenly became red, faintly, like a fire cloud, permeating the sky, blocking all the way.

As it gradually approached, the fiery cloud-like thing was finally clearly seen by Lin Dong, and his brows couldn't help but pick up.

It was a sea of red fire that I didn't know where it spread, and the sea of fire was rising, as if it was burning this space, and around that sea of fire, the already broken space was even more incinerated and showed signs of distortion, and the space was extremely unstable.

"Nirvana Burning Heaven Array ......".

Lin Dong stared at this spectacular scene, but his mouth was muttering to himself, on the stone tablet, he already knew that in the deepest part of the ancient secret, there was a formation guard, and obviously, this sea of fire in front of him was the so-called formation, and its name was called the Nirvana Burning Heaven Array.

If you want to enter the deepest part of the vault, you must pass through the Sea of Fire through the Piece Formation.

In this formation, the burning flame is not an ordinary fire, but a flame condensed by the qi of Nirvana, which is the same as the fire of Nirvana, even if the strong people of the Nirvana realm stay in it for a long time, they will burn the qi of Nirvana in their bodies, and thus fall, which can not be said to be fierce.

Lin Dong looked at this endless sea of fire, and praised it with a sigh of praise in his mouth, this thing is probably the real roadblock, I don't know how many strong people will be discouraged here.

"Hey, this formation isn't easy, you have to be careful. The little mink flashed out, glanced at the sea of fire that filled the space in front of him, and reminded him with a little surprise.

"Hmm. Lin Dong nodded, he is not a fool, this and the formation are the main treasures used by the huge sect alliance to protect them, even after the passage of time, its power is still terrifying, and it is really a fool to underestimate it.

Lin Dong looked around, and could vaguely see some figures coming from a distance, and finally they were all suspended outside this sea of fire, they hesitated slightly, and finally gritted their teeth and rushed in one after another, it seems that the inheritance of the Four Xuanzong is really extremely attractive

"Let's go. ”

Lin Dong waved his hand, and without hesitation, his body moved, and he rushed directly into the sea of fire, and behind him, Xiao Yan was also holding an iron rod and quickly followed.

As soon as he rushed into this sea of fire, a terrifying heat wave was coming, and immediately Lin Dong felt that his skin became red, and as soon as his heart moved, invisible spiritual power poured out, forming an invisible barrier around his body, isolating the terrifying heat wave.

In this Nirvana Burning Heaven Array, as long as there is the existence of Nirvana Qi, it will be automatically ignited, so no one dares to urge Nirvana Qi here, and even some people even urge Yuan Li, they have to be careful, after stepping into the Nirvana realm, Yuan Li has experienced the tempering of Nirvana Qi, and no one will be able to be burned here......

Obviously, Lin Dong has no such concerns, his spiritual power has nothing to do with the qi of nirvana, and it is perfect to resist the erosion of the fire of nirvana.

The invisible spiritual barrier encompassed Lin Dong and Xiao Yan a lot, and then the two of them also turned into rainbows, tearing through the sea of fire like lightning, and advancing towards the depths.

And when he swept through the sea of fire, Lin Dong's spiritual power spread, always vigilant of the movements around him, from the stone tablet he knew that this Nirvana Burning Heaven Array was terrifying, if it could really be so easy for people to break through, then the prestige was a little too funny, and obviously, with the ability of that sect alliance, it was impossible to do this and things.

"Huh?"

Obviously, it turned out that Lin Dong's prediction was unreasonable, and not long after they broke into this Nirvana Burning Heaven Array, there was a sudden slight movement in the Nirvana Fire surging around.

Woohoo!

The abnormal movement was noticed by the vigilant Lin Dong at the first time, his eyes were fixed, and then he saw that in the pervasive sea of fire, there was suddenly a stream of firelight swept by, and in the firelight package, there were fist-sized small red balls, and the violent fluctuations emitted from the balls made Delin's eyes shrink slightly.

"Nirvana Fire Thunder!"

For these strange balls, Lin Dong obviously recognized their details, and immediately his face became a little dignified, this and Nirvana Fire Thunder, is condensed by pure Nirvana Qi, but it is extremely violent, it explodes when touched, and the power is extremely powerful, just one, it can blow up an ordinary Nirvana powerhouse into serious injuries, if the number is large, even Lin Dong's strength to survive a Nirvana Tribulation will become an extremely headache.

Obviously, these Nirvana Sharp Thunder Ten Flying Sutras that appeared in front of him reached the point where Lin Dongcheng was in danger.

Xiao, Yan clenched the iron rod in his hand, and looked vigilantly at the Nirvana fire thunder that swept from all directions, it seemed that he also felt some danger.

"Boy, don't touch these things, there are countless Nirvana fire thunders in this Nirvana Fire Array, if it causes an explosion, I'm afraid it will cause a chain reaction, and when the time comes, thousands of tens of thousands of pieces will come, don't say that your strength in this Yuan Nirvana, even if you survive another Nirvana Tribulation, you will have to be blown to pieces. The mink sprang out at this moment and admonished.

Hearing this, Lin Dong frowned, feeling that it was very tricky, if he didn't solve these nirvana fire thunders, he would obviously not be able to take a step forward.

"Stupid, what are you doing with your Devouring Ancestral Talisman? No matter how violent these Nirvana Fire Thunders are, they are also condensed by Nirvana Qi, as long as it is energy, Devouring Ancestral Talisman can swallow them!" Seeing Lin Dong's embarrassment, Xiao Mink couldn't help but scold.

A word to wake up the person in the dream, Lin Dong suddenly realized, he had forgotten that no matter how violent this Nirvana Fire Thunder was, after all, it was still Nirvana's qi ......".

Laugh at!

With a solution, Lin Dong did not procrastinate, his mind moved, and a circle of black holes spread out from behind him, and then the devouring power surged out, and the Nirvana fire and thunder that swept from the surrounding sea of fire roared directly, and finally shot into the black hole.

Bang bang bang!

Inside the black hole, there was a faint muffled sound, and the qi and blood in Lin Dong's body were also churning slightly, but immediately after, there were waves of childish and powerful nirvana qi pouring into his body from the black hole.

With such a surging Nirvana Qi pouring in, a flash of surprise flashed on Lin Dong's face, which was faster than cultivating in the Dan River.

The figures of Lin Dong and the others quickly swept through the sea of fire, and the Nirvana fire thunder that kept shooting was all sucked into the black hole, and finally turned into the rolling Nirvana Qi, flowing in Lin Dong's limbs and bones, refining his ** from the inside out.

This twilight, slightly a little spectacular and terrifying, if it is seen by others, I am afraid that it is indispensable to be dumbfounded, this and place, even if it is similar to Liu Bai and their level, they only dare to carefully slow down and walk, who dares to exert speed to the extreme like Lin Dong, and under the bombardment of so many Nirvana fire and thunder, the more and more he runs, the happier he is?

Lin Dong's harmony swept for more than ten minutes, but the sea of fire still did not see the end, this way, he absorbed a large amount of Nirvana fire thunder, at this time, the inside of the body, there was a faint feeling of puffiness, that huge Nirvana Qi, even with his ** strength, it was not completely absorbed for a while and a half.

However, his rushing did not last until he reached the end of the sea of fire, perhaps because of his wanton absorption, he finally attracted some more powerful things that existed in this Nirvana Burning Heaven Array......".

Laugh at!

Lin Dong's rushing figure suddenly froze, and the abrupt change between extreme movement and extreme stillness made people's vision slightly uncomfortable, but at this moment, Lin Dong didn't pay attention to these, his eyes were already staring at him in front of him, where, the fire of Nirvana was burning, and in the fire of Nirvana, a pale black flame was quietly suspended, the flame was constantly wriggling, as if it had spiritual intelligence, and sometimes changed into the shape of a beast or even a human face, which was extremely weird.

Lin Dong looked at this pale black flame substance in a daze, but his scalp suddenly became a little numb, his mouth moved dryly, and after a while, a low voice came from his throat.

"This is the ...... of Nirvana's Demon Flame"
