As Ling Qian's voice fell, the upper part also became quiet, but their hearts were not at peace.

In the boundless sea of demonic qi, a light and shadow mixed with black thunder passed quickly, and everywhere it passed, the surrounding demonic qi frantically eroded away.

The two ancient runes flowed slowly, directly evaporating all those demonic qi.

In the light mask, Lu Yan closed his eyes slightly, and his spiritual power spread, trying to sense the existence of the legendary Infernal Lord in the sea of demonic qi as much as possible.

However, his induction obviously did not, and he quickly got the result, this demon sea is quite vast.

Moreover, the demonic aura that permeated it also caused considerable obstacles to Lu Yan.

It is obviously not easy to quickly find the Infernal Lord, hidden somewhere in it.

"Now you haven't arrived at the Demon Sealing Prison at all, this sea of demonic energy is just leaking out of the Demon Sealing Prison, you have to pass through this Demon Sea to reach the Demon Sealing Prison. ”

After Lu Yan did some useless work, Xuan Lao slowly reminded him.

Lu Yan 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 Lu Yan 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.

A cold feeling wrapped around his body, which made De Lu Yan a little frightened, but fortunately he had two major rune seals.

Otherwise, I'm afraid that at this time, I would have been eroded by demonic qi and lost my sanity.

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

This shuttle lasted for half an hour again, Lu Yan's eyes froze violently, and he could perceive the demon sea below.

There were some interruptions at first, but the intensity of the demonic aura that permeated there became more and more terrifying.

"Well, be careful, the Hellseal is not unusual. Xuan Lao this time, he immediately reminded him.

His voice became a little more solemn at this time, which made De Lu Yan's heart tense a little, and he was also extremely afraid of the legendary Demon Sealing Prison.

Lu Yan'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 through 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 Lu Yan at this time did not pay attention to these.

His gaze looked downward, and then a touch of shock slowly climbed up his face.

What appeared in front of Lu Yan was a dark light mask with no end in sight, and above the light mask, dark runes were filled.

Looking closely, it is actually somewhat similar to the Xuanji Dark Realm Talisman, and this light mask seems to be a huge magic circle.

It's just that now, on this light mask, there are some dim cracks, and streams of demonic qi seep out of the cracks and merge into the demon sea above.

When you look through the dark black light shield, you can see that in it, there is a dense tower of darkness suspended.

On top of each black tower, there are huge black chains entwined, and then the chains extend out, connecting the black towers together.

Above those black chains, covered with ancient runes, an extremely powerful wave emanated.

Countless evil demonic auras were mad, permeating the Tower of Darkness, but every time they were bursting out.

It will be absorbed by the black chains, and then the ancient runes will flicker, purifying all the demonic energy.

"Is this the Demon Seal..."

Lu Yan looked at the dark light mask and the dark tower group with no end in sight within the light mask.

Each of the black towers was thousands of feet high, and he looked extremely small when he stood here.

And what's even more terrifying is that the number of these dark towers is also immeasurable.

Obviously, among these dark towers, the demons are sealed, and such a number of black towers, the demons sealed in them, should have reached a terrifying number.

"Now can you imagine how amazing the ancient war between heaven and earth was?" Xuan Lao said lightly.

Lu Yan nodded slightly, no wonder all the creatures in this plane were united at that time.

In the face of this horrific invasion, no race is immune.

"As long as there is a second emperor, it's fine. Xuan Lao seemed to know what Lu Yan was thinking, and said softly.

Lu Yan smiled bitterly, the second emperor, this is not a simple matter.

"Let's find the Infernal Lord first. ”

Lu Yan 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?" Lu Yan didn't dare to trespass at this time, in case it caused the magic circle to rebound, I was afraid that he would die quite unjustly.

"You have the power of the sigil, you can directly penetrate it, and if others say it, even the spirit will be difficult to enter. Xuan Lao replied.

When Lu Yan 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, Lu Yan breathed a sigh of relief, and as soon as his body moved, he got into the dark light shield.

Entering the light mask, Lu Yan found that this demon prison was not quiet, and from time to time there were all kinds of screaming sounds, coming from the black towers.

This kind of scream also has the ability to corrode people's minds, but fortunately, Lu Yan has two major runes and a Xuanling jade pendant, so he is not too afraid.

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

Lu Yan swept out, cautiously shuttling through the Demon Sealing Prison, and then saw some signs of corrosion in some huge chains wrapped around the Black Tower.

The ancient runes covered with it are also dim, and some demonic qi will burst out from this direction, and then drill out from the crack of the dark light mask above.

"The existence of the Demon Prison has been too long, and the previous spiritual impact on the life and death tribulation has destroyed the balance of energy here, so it has caused the demonic energy to overflow. "Xuan Lao said.

Lu Yan nodded slightly, and his figure sped up, and in this demon prison, he only realized the enormity of this place.

After half an hour of flying, I still couldn't see the end of the Black Towers.

Lu Yan frowned and searched hard, and suddenly, his expression moved, and some strange voices came into his ears.

Immediately tilted his head, and even his pupils shrank, and he saw that he was on top of an extraordinarily large black tower.

There was a coiled black chain, which broke at this moment, and a clattering sound sounded here......
