Mu Xuan was speechless, and his teeth were really tight on this guy's slackness, but at this time, he could only grit his teeth and rush towards the demon sea with his head down.

And as Mu Xuan quickly shuttled through the demon sea, he also found that as he went deeper and deeper, the demonic qi that came out of the ground below became more and more intense, and a kind of cold feeling was wrapped around his body, which made Mu Xuan a little frightened, fortunately, he had two heavenly will protectors, otherwise, I am afraid that he would have been eroded by the demonic qi at this time and lost his sanity...

"It seems to be about to penetrate this sea of demons..."

This shuttle lasted for half an hour again, Mu Xuan's eyes froze violently, and he could sense that the demon sea below began to have some interruptions, but the intensity of the demonic qi that permeated there was becoming more and more terrifying.

"Well, be careful, the Demon Forbidden Land is not an ordinary place." Xiao Gollum immediately reminded him this time, and his voice became a little more solemn at this time, which made Mu Xuan's heart tense a little, and he was also extremely jealous of the legendary Demon Sealing Forbidden Land.

"It's out."

Mu Xuan's eyes stared closely at the churning demon sea in front of him, and then he let out a soft drink, and his body wrapped in the light mask finally pierced out the sea of demonic qi that was so thick that it was almost viscous.

The body passed through, and the originally blurred vision was also suddenly clear, and the surrounding demon sea also dissipated at this time, but Mu Xuan at this time did not pay attention to these, his gaze looked down, and then a touch of shock slowly climbed up his face.

What appeared in front of Mu Xuan was a dark light mask with no end in sight, above the light mask, there were dark ancient patterns, if you looked closely, it was somewhat similar to the Heavenly Dao Ancient Patterns, this light mask seemed to be a huge formation, but now, on this light mask, there were some dim cracks, and streams of demonic qi seeped out from the cracks and merged into the demon sea above.

Eyes through the dark black light shield, you can see that in it, there is actually a dense tower of darkness suspended, on each black tower, there are huge black chains entangled, and then the chains extend out, connecting the black towers together, on top of those black chains, covered with ancient runes, an extremely powerful wave emanated.

Countless evil demonic qi frantically diffused from the dark tower, but whenever they burst out, they were absorbed by the black chains, and then the ancient runes flickered, purifying all the demonic qi.

"Is this the Demon Seal..."

Mu Xuan looked at the dark light shield in front of him in a daze and the endless dark towers in the light mask, each of which was thousands of zhang high, he looked extremely small standing here, and what was even more terrifying was that the number of these dark towers was also immeasurable...

Obviously, these dark towers are sealed with demons, and with such a number of dark towers, what kind of terrifying number of demons should be sealed in them?

"Can you imagine how amazing that ancient battle was?" Little Grunt said lightly.

Mu Xuan nodded slightly, no wonder all the creatures in this plane were united at that time, and in the face of this terrifying invasion, no race was spared at all.

Except for war, it is death.

And if a war like the one back then starts again, what will the world look like? Now, will they be able to resist the invasion of the terrible demon clan again?

"As long as there is a second Dao Heaven, it's fine." Xiao Gulu seemed to know what Mu Xuan was thinking, and said softly.

Mu Xuan smiled bitterly, the second Dao Tian... It's not an easy thing to do.

"Let's find the Immortal of the Eternal Night first."

Mu Xuan sighed lightly, and then his body moved, cautiously approaching the dark light mask, on which he sensed a rather terrifying energy fluctuation.

"How do you get in?" Mu Xuan didn't dare to break in at this time, in case it caused the formation to rebound, I am afraid that he would die quite unjustly.

"You have the power of the will of the Heavenly Dao, you can directly penetrate it, and if others say it, even Ao Guang will find it difficult to enter." Little Grunt replied.

When Mu Xuan heard this, he nodded, but he still cautiously stretched out his palm and gently touched the dark light mask, the light mask rippled, but his palm penetrated unscathed.

Seeing this scene, Mu Xuan breathed a sigh of relief, and as soon as his body moved, he got into the dark light mask, and entered the light mask, Mu Xuan found that in this demon prison, it was not quiet, and from time to time there were all kinds of screams coming from the black towers, this kind of screaming also has the ability to corrode people's sanity, but fortunately, Mu Xuan has the will of the two heavenly daos, so he is not too afraid.

"Some of the chains seem to have been eroded..."

Mu Xuan swept out, carefully shuttling through the Demon Sealing Prison, and then saw some signs of corrosion in some of the huge chains wrapped around the Black Tower, and the ancient runes covered with them were also biased towards dimness, while some demonic qi would come out from this direction, and then drill out from the cracks in the dark light mask above.

"The existence of the Demon Forbidden Land is too long, and the previous Ao Guang Impact Martial Immortal Realm destroyed the balance of energy here, so it caused the demonic qi to overflow." Little Grunt.

Mu Xuan nodded slightly, and his figure sped up, and in this sealed demon forbidden land, he only realized the huge size of this place, and after flying for half an hour, he still couldn't see the end of the Black Tower Group.

"Huh?"

Mu Xuan frowned and searched hard, suddenly, his expression moved, and some strange sounds came into his ears, and he immediately turned his head, and even his pupils shrank, and he saw that on top of an extraordinarily large black tower, a coiled black chain suddenly broke at this time, and the sound of the chain falling sounded piercingly in this demon prison.

"The chains of the seal are broken?"

Mu Xuan looked at the broken chain, his scalp instantly became numb, and his figure hurriedly swept out.

Roar!

And at the moment when he swept out, in the dark tower, a fierce beast-like roar came out, and a monstrous black mist swept out, turning into a huge demonic qi giant M, and pounced on Mu Xuan with teeth and claws.

Mu Xuan felt the evil fluctuations behind him, and his face changed greatly. He could sense that there was a large amount of chaotic and murderous consciousness in that demonic qi giant M, obviously it was not a single thing, but a gathering of many powerful demons, they had broken through the dark seal now, and their consciousness was not too clear, but this did not prevent them from feeling the fluctuation from Mu Xuan that made them quite disgusted.
