Because of what happened just now, Mu Yu missed the most convenient way to the eighty-first floor, he was currently on the sixty-seventh floor, which was a vast and boundless sea, with only a lonely island, and he would have to wait another three hours before he could leave this level.

The island is less than twenty square meters, and there is a hole in the ground, which is the exit to this level. The blue sea rippled all around, the white clouds scattered in the sky, and nothing else, not even a seabird.

"Anyway, why did Xuanjizi Zhenren set up such a strange phantom array in the Demon Suppression Tower? This layer is an endless sea, what's the point?" Xiao Shuai said boredly.

"Who knows! Do you think there will be a little mouse in the sea here, your big lover? Long Teng said with a wicked smile on his face.

"Phew,, what a big lover! I forgot what it looked like if you didn't mention it!" scolded the little handsome angrily.

Long Teng laughed: "It's okay if you forget, I know what Xiao Momo looks like, I'll help you recall." It is a gorilla on the upper body and a big octopus on the lower body, with strong muscles and dark skin, and the eyes are a little shy when it looks at you, I feel that it is very likely to jump out of the sea to find you, haha!"

"Whoa!"

There was a violent sound of breaking water, and then a behemoth suddenly came out of the water, covering the sky and the sun, and the shadow really enveloped the entire small island.

The upper body of the gorilla and the lower body of the octopus are a seventh-order ink demon ape!

Xiao Shuai staggered, sat on the ground, and opened his mouth wide: "Ah, no, won't, it's really Xiao Momo!"

Mu Yu was also surprised, the aura of the ink demon ape in front of him was the same as the little ink ink in Xiao Shuai's mouth, especially this ink demon ape was really looking at Xiao Shuai with shy eyes, with affection. Finally, he stretched out a tentacle and gently touched Xiao Shuai, and then called out "hiss".

"My God, why did Xiao Momo appear here?" Long Teng was also startled, it just said casually, how would it know that Xiao Momo really appeared.

"No, it's not real, it's an illusion. I see, this formation is called 'Chaos Beginning', and there are no creatures, but what you have in mind will appear. Mu Yu's eyes flashed with formation lines, and he saw the essence of the ink demon ape in front of him clearly.

The formation of "Chaos Beginning" is very mysterious, because it completely relies on the spiritual power of cultivators to construct a world, and whatever they want to create, they will appear in this world. This formation is very profound, at least with Mu Yu's current cultivation, he can't arrange such a powerful formation.

"Huh, doesn't that mean that if I think about the appearance of a big earthworm, a big earthworm will appear?" Xiao Shuai's eyes rolled, and his brain quickly simulated the appearance of the dragon vine, but when it imagined it, it deliberately lost one of the dragon horns of the dragon vine.

"Roar!"

The dragon vine, which was missing a dragon horn, roared out of the sea and soared freely in the air.

"Little mouse, are you looking for death?" Long Teng was furious, and then shouted, "Then I also want you without a mouth, I see how you can eat!"

Sure enough, another handsome man flew up from the sea, and this little handsome man danced with his hands, but he didn't have a mouth.

Then it was the two idle guys who began to compete with each other for their imagination.

Xiao Shuai and Long Teng began to happily imagine each other's funny appearances, and soon a large number of strange Long Teng and Xiao Shuai appeared over the sea, including Xiao Shuai with a missing arm, Xiao Shuai with a pig nose, Xiao Shuai with cross-eyed eyes, and Xiao Shuai with a watermelon hat......

A dragon vine with a beard that turns into two hemp ropes, a dragon vine with a dead knot on its body, a cute pink dragon vine, and a dragon vine with two big waves on its chest......

Mu Yu carefully looked at the funny versions of Xiao Shuai and Long Teng flying around in the air, he was not so boring as these two, but was thinking about the intention of the formation of "Chaos Beginning".

This formation is quite profound, Mu Yu once saw it in Daddy Deadwood's "Xuan Array", the things that are illusioned in this formation are related to people's spiritual power, and the more complex the thing, the greater the spiritual power required.

If you deplete too much mental energy, you will feel tired at that time.

"You guys don't think too much and you'll lose your energy. Mu Yu warned.

Sure enough, not long after, the momentum of the quarrel between Xiao Shuai and Long Teng had passed, and they stopped listlessly, and now the air was full of Xiao Shuai and Long Teng flying around, as well as some chicken legs with wings, roast suckling pigs on fire, and roast duck with attractive colors......

Although the imaginary things are not real, the breath will not be fake, just like the ink demon ape, if it weren't for Mu Yu's familiarity with the formation, he wouldn't be able to tell the difference.

When Xiaoshuai and Long Teng got tired and began to lie down to sleep, those fantasies gradually disappeared. However, Mu Yu thought of one thing, relying on the formation technique of "Chaos Beginning", as long as he mastered it reasonably, he could do a lot of things.

On the demon island, Mu Yu can only rely on Heliankong's help to compete with the ghost gate, if the entire demon tower's formation field is unlocked, Heliankong will be freed, and then Mu Yu will have to face the pursuit of all the ghost gate.

As for the ghost domain, Mu Yu didn't believe that this guy also wanted to be freed, he would definitely survive with the ghost art of the ghost gate people, and it was possible for the ghost gate people to cultivate their souls to this point. And when Chaos first opened this formation technique, Mu Yu was thinking about how to use it reasonably, so as to leave a way back for himself when the time came.

Mu Yu rested for a long time, but he didn't meet anyone else on the next journey, he took Xiao Shuai and Long Teng, who fell asleep because he was too tired from playing, and spent seven hours, four of which turned, and finally came to the eighty-first floor!

He turned to look at the passage, which was a whirlpool in the air, from which he had just come.

All around is a vast white cloud, and you can see a towering mountain peak. The green mountains and green waters, the waterfalls flowing, and the pines and cypresses are stubbornly rooted and growing in the stone crevices on the mountain. The top of the mountain is covered by white clouds, and it is peaceful and relaxing.

There is nothing else but this mountain.

This mountain is a little familiar at a glance, but Mu Yu has been wandering around in the cultivation realm, and he has even been to the Second Heaven many times, and he has seen countless mountains, and he has not remembered where he has seen this mountain for a while.

Mu Yu flew towards the mountain peak in mid-air, but as he flew, he noticed that something was wrong.

He was now in a distracted period, and he flew extremely fast, flying from the whirlpool towards the distant mountain peak, which seemed to him to be only a blink of an eye. But in the blink of an eye, he couldn't fly for a long time.

Mu Yu turned his head to look behind him, and was surprised to find that after flying for so long, the whirlpool passage that came in was still behind him, and he didn't fly over at all!

"Is this—the end of the world?" Mu Yu nodded thoughtfully.

The formation technique of "close to the end of the world" was taught to him by Mu Yu when he was in the formation sect before, and it can "shrink the ground into inches and expand the land into boundless", and really make a distance become "close in front of you, far away in the sky", which is impossible to get close at all.

Mu Yu rarely uses this formation technique, and this formation technique is somewhat effective against fellow cultivators, but it will be very thankless to deal with people whose cultivation is much higher than his own.

The formation technique of the end of the world here was set up by Xuanjizi Zhenren, and it was impossible to crack it with Mu Yu's cultivation, and he had to approach the mountain according to Xuanjizi Zhenren's law.

It's just that where is the Tianyan Reincarnation Seal on this mountain?

"No! This is not a mountain, this is - this mountain is the Tianyan Reincarnation Seal!"

Mu Yu was a little shocked in his heart, no wonder he found that this mountain was still a little familiar at first, it turned out to be because of this!

It turns out that the eighty-first floor of the Demon Town Tower is the transformation of the Tianyan Reincarnation Seal, where the Tianyan Reincarnation Seal seems to have been enlarged, and it is no longer a small thing. This kind of tricky way of arranging the formation even opened the eyes of Mu Yu, the master of the formation rune gate!

Although Mu Yu knows many formations, the formation of Xuanjizi Zhenren is still far above Mu Yu, which Mu Yu has to obey.

A formation close to the end of the world was set up near the Tianyan Reincarnation Seal, so that people would not fly directly over. He simply fell down the mountain, passed through the clouds, and saw the gossip formation at the foot of the mountain peak, which was indeed the base of the Tianyan Reincarnation Seal.

Mu Yu stood steadily at the foot of the Tianyan Reincarnation Seal, looking at the towering peaks that were bottomless, but he still made a difficulty.

He didn't know if Ghost Regret had come here in advance, and he didn't know if Ghost Regret knew how to open the Tianyan Reincarnation Seal to go back to the past, at least he didn't know how to control this Tianyan Reincarnation Seal.

"I remember there was a cave halfway up the mountain, and a platform, could that cave be a way back to the past?"

Mu Yu pondered for a moment, he glanced at Xiao Shuai and Long Teng, who were sleeping at the moment because of their greedy playfulness just now, and did not wake up the two little guys, and walked towards the mountain peak by himself.

If he walked from the foot of the mountain, the formation technique of the end of the world did not work on him, and he soon came to the foot of the mountain. He knew that he might be stopped by the end of the world again as soon as he flew up, so he walked around the foot of the mountain and finally found a way up the mountain.

The mountain road was carved out of winding stones, and the side of the road was full of small flowers and grasses, and to Mu Yu's surprise, the small flowers and grasses here were all real plants! There were also crickets chirping around, frogs flashing, and small squirrels running around on the pine trees on the side of the stone road, and birds jumping and flying among the branches.

Nothing in this mountain is made up of formations, it's like a small world, and everything really exists.

On the side of the road up the hill there is a small stone monument with a small line of poems written on it:

"The Commandment of the Mountain Walker"

Tianyan reincarnation steals for a long time,

Eternal life is free to be desired.

The past is still in ashes,

Is it changeable to come to Japan?

Be kind to the future of Pepsi,

Don't make the gold bottle empty to the moon.

Mu Yu read this poem carefully, the general meaning of this poem is very clear, it seems to be explaining that Tianyan reincarnation seal has some relationship with eternal life, but then he is exhorting people who go up the mountain not to be nostalgic for the past, and to pay attention to the present is better than anything else. However, this poem also proves that it is indeed possible to use the Tianyan Reincarnation Seal to go back to the past.

For Mu Yu, there is nothing to force, he came here more to prevent the ghost from sparing his life, of course, if he can go back to the past, know where the treasure of the ghost gate "Crossing the Soul and Returning to the Heart" was left, and then find it is the best.

It's a pity that Mu Yu still doesn't know what "Soul Crossing and Returning to the Heart" looks like, and if he wants to find the Soul Crossing and Returning to the Heart, he needs the help of the ghost.

With this in mind, he set out on the road up the mountain.
