Looking up at the three-story staircase, the extended wooden ladder is only more than ten zhang long, and the end can be said to be close at hand.

But when Chu Mu stepped on the wooden ladder, this seemingly ordinary wooden ladder seemed to be infinitely extended, and he crossed hundreds of zhang in an instant, but there was still no end in sight.

Even, the further up you go, the darker the wooden ladder becomes visible to the naked eye.

Even the lamps embedded in the walls on both sides of the wooden ladder were obviously a little cold and cold as Chu Mu moved forward.

In the past, even the light color emitted by the lamp was a little more enchanting light blue cold light, like a cold flame in the ice, piercing cold.

Chu Mu looked at this abnormality, and a little surprise was clearly visible between his eyebrows.

Such an anomaly, as far as the immortal path system is concerned, there are not many possibilities, and it can even be said that there are very few.

Either he quietly fell into an illusion and evolved into an illusory realm, no matter how abnormal it was, it was not impossible.

But the question is, whether he has fallen into a hallucination, he himself is naturally very clear.

A touch of spiritual blessing, a touch of knife sharpness, want to let him quietly fall into the illusion, even if it is a Yuanying Great Monk, I am afraid it will be difficult to do.

Or, it is the unknown above the third floor of this Langya Pavilion, but it is a space that does not belong to this secret world at all.

An existence similar to a realm within a realm.

And this kind of realm within the realm, in the realm of cultivating immortals, also has a unique name.

Namely...... Xianfu.

In short, it is the most common cave mansion in the immortal cultivation world today.

It's just that at the time of the Ancient Heavenly Palace, some great supernatural powers often liked to open up a realm in the middle of a realm as a cave for their own cultivation.

And with the collapse of the Heavenly Palace, the passage from the upper realm was cut off, and many inheritances, and even many rare spiritual objects in the upper realm were also cut off, and the existence of the immortal mansion gradually withered in the world.

As far as he knew, today's Immortal Sect Sect Hall is actually an immortal mansion handed down from ancient times, at the beginning of the establishment of the Immortal Sect, it was moved to the top of the Immortal Mountain by the first sect master of the Immortal Sect with great power, and since then it has solidified into the Immortal Sect Palace, which has been passed down to this day.

Chu Mu glanced down at the Qiankun bag hanging from his waist, his Qiankun space, if the bag of the entity exposed in this realm was turned away, and turned into a permanent space fixed in the immortal cultivation realm, it could also be said to be a realm within a realm, and an immortal mansion.

Of course, his Qiankun space is only a prototype after all.

And the so-called Immortal Mansion, the so-called realm within the realm, and even the so-called secret realm world, there is obviously no difference in their essence.

The difference is only in whether the world is complete or not.

A secret world can even be regarded as a small world, in which the heaven and earth are stable and the rules are perfect.

His Qiankun space, up to now, is still only a prototype, and can only be called space, not heaven and earth.

And the Immortal Mansion is between the two, which is more complete than his Qiankun space, and a little inferior to the small world of the secret realm.

His thoughts flashed away, and Chu Mu not only did not stop, but instead sped up a few points.

Although I don't know what happened in the battle of Langya that year, this secret world was left behind for many years, but the facts are undoubtedly very clear, the secret realm has been lost for many years, and in the inner part of the secret realm, except for Wang Xun, there are no other royal monks.

This side in front of him may be the realm within the realm of the Immortal Mansion, and in the absence of an owner, it is impossible to pose much of a threat.

As Chu Mu sped up, the increasingly dark and cold staircase passage also swept by his side, and in the end, the dark and cold that was originally only slightly revealed was almost condensed into a substantial coldness.

The stairs were dyed with frost, and the walls on both sides had become dark blue ice walls, and even the scorching lights exuded a biting chill.

At the end, a frozen dark red metal gate towers.

The portal was heavy, and even if it was stained with frost, it couldn't hide the hideous forms of the various demon beasts carved on the metal portal.

At a glance, the monstrous demon beast seemed to be alive, with a deafening roar exploding, and bloodthirsty eyes stared at Chu Mu, an alien intruder, as if they were about to be killed at any time......

"Broken!"

Chu Mu let out a low shout, the knife came out like a dragon, and between the darkness and coldness, a touch of the knife flew by, and the visions that sprung up were all broken in an instant.

At this time, this heavy metal gate stained with frost returned to silence and simplicity, and it was difficult to see the slightest vision.

Chu Mu stopped in front of the door, and a touch of divine consciousness flowed, and it was difficult to get a glimpse of it through this portal.

He hesitated for a moment, and between the rolls of his robes, a puppet stood in front of him, and as soon as he gave an order, the puppet immediately stretched out two metal arms and touched the frost portal.

At this moment, Chu Mu also retreated a few feet, and several armor puppets were protected in front of him, watching the contact between this armor puppet and this portal.

When the armor puppet came into contact with the frost portal, there was no vision he expected, just like an ordinary push door, this heavy frost portal, under the impetus of the armor puppet, was slowly pushed, a gap, also from small to large.

Eventually, the door opened, and the biting cold air flowed through the portal, reaching the deep staircase, and the coldness of this staircase passage was obviously a little thicker in just a few breaths.

And inside the portal, the cold and cold air surged, and it was difficult to see the slightest hint of it, only the puppet of the armor, under the order of Chu Mu, stepped into the rolling frost without hesitation, and submerged into the portal that was pushed open.

In just a moment, a message was sent back from the portal.

After only a few breaths, Chu Mu's figure flickered, and he stepped into this portal under the protection of several armor puppets who were ranked at the top of the third order and were not weaker than the monks of the late stage of Jindan.

Compared to the darkness of the staircase, when Chu Mu stepped into the portal, he only felt that his vision suddenly brightened a little.

As far as the eye can see, it is like a world of frost.

The ground is like a cloud of frost and cold air, a statue hidden in the cold, looming ice sculptures are either majestic or short, with different postures and lifelike.

Above the head, it was like ten thousand sharp blades hanging high, and the ice spikes that condensed into substance were undulating.

In the midst of this cold surge, the divine sense was also obviously limited, and it was limited to a range of only a few feet around the body, and it was difficult to advance the slightest.

There is no restriction on direct vision with the naked eye, and everywhere you can see can be included in the field of vision, but it is limited to the cold surging, and the distance from the naked eye is only about a few zhang.

Several armor puppets surrounded the guards, and Chu Mu looked around, and finally stopped in front of an ice sculpture not far from his side.

The ice sculpture is about ten zhang high, about ten zhang long, and the overall form, like a giant crocodile crawling forward, is staring at its prey, and even the tyrannical and bloodthirsty meaning in its eyes is extremely clear.

At this moment, Chu Mu's calm expression finally showed a little waves.

He hesitated, hesitated for a moment, and finally raised his hand to caress the giant crocodile ice sculpture.

The touch was cold, the biting chill eroded almost instantly, and the fingertips were also visibly stained with frost, Chu Mu turned a blind eye, and a touch of divine sense permeated this giant crocodile ice sculpture along his fingertips.

Normally, inside an ice sculpture, it must be a biting cold, a pure dead thing, but when Chu Mu's divine sense penetrates into it, what is perceived is the frozen dead silence, but it seems to be ......

"Lava Crocodile ......"

Chu Mu became more and more suspicious, in his divine perception, this so-called ice sculpture did not seem to be a pure ice sculpture, but a genuine third-order lava giant crocodile.

And when the consciousness penetrates again, through the outside of the dead silence, into the inside, between the frozen dead silence, a looming vitality is actually incorporated into the divine consciousness......

Chu Mu was stunned, he subconsciously spread his divine sense to peep, and with the flow of his divine consciousness, this frozen lava giant crocodile was incorporated into the perception in more detail, and a fact that seemed even more unbelievable was also presented.

This frozen lava beast .........

Still alive?

Chu Mu couldn't hide his surprise, there were genuine demon beasts among the ice sculptures, which was not surprising.

But such a dead and frozen state can still retain its vitality, and from his peep view, this preservation of vitality can even be said to be extremely perfect.

Perfect to ......

He even felt that as long as he unraveled this frozen state, the third-order lava giant crocodile that was frozen in it would wake up in an instant!

After a short period of surprise, Chu Mu subconsciously looked around, and just as far as his naked eye could see, he could see many ice sculptures towering.

This lava giant crocodile is a real demon beast, and it also retains traces of life in this ice, and the other ice sculptures ......

This world of frost ......
