There was no danger along the way, but this did not make Xiao Yu feel a little relaxed in his heart, on the way they didn't even encounter a decent demon beast, and naturally they didn't get any elixir ores, he didn't regret that he didn't get the treasure, but the road was too quiet.

It is said that the deeper you go to the secret realm, the more dense the demon beasts should be, and the grade of the elixir ore should also be higher, but they came here so easily, which can only show that there are already people walking in front of them, and there are still many people, and the strength should not be underestimated, otherwise the demon beasts along the way will not be cleaned up so cleanly.

Noticing Xiao Yu's unusually cautious expression, Xiao Jiumei also found an unusual atmosphere, although she is usually naïve, but she is not stupid, but Xiao Yu usually has to worry about things in her brain, and gradually she is used to being lazy, and now she also finds that this road is too smooth, such a quiet atmosphere is really abnormal, so she also pulled the Feihong Sword out of the sheath and held it tightly in her hand.

At this time, they had already arrived at a place marked on the map, and they were all puzzled by the fact that there was nothing special here except for a tree hole that could only accommodate one person, and out of caution, they did not rush into the tree hole.

Xiao Yu once again left the two girls in place, and then came to the entrance of the tree hole, and turned the divine thought into an extremely slender soul silk and probed into the tree hole, as he expected, this tree hole is not as narrow as the surface, and there is a hole inside.

The tree hole is very wide, and even with his current Yuan Shen realm, there is no way to detect the edge of this tree hole, Xiao Yu's divine sense covers a radius of ten miles without any effort, but he can't completely explore the situation of this tree hole, and he doesn't even know how much he can stand in this tree hole in the area he explored, which shows how big this tree hole is.

Although they can't fully understand the situation in the tree cave, there must be something unusual in such a weird tree hole, immortal cultivators are born with a hobby of seeking secrets, it is because they have touched things that mortals can't touch in their lives, so they will be more curious about the secrets of the world, Xiao Yu is no exception, he also has a curiosity about unknown things.

After preliminary exploration, there didn't seem to be any danger in the tree hole at present, so he beckoned to the two girls behind him, and then he stepped into the tree hole first, when Xiao Jiu Mei and Ling Caiyan entered the tree hole, their eyes flashed with incredible looks, and they were all sighing at the magic of creation, in the tree hole that looked so inconspicuous on the outside, but it was so incredible inside.

Xiao Yu had already observed the situation in the tree hole through his divine sense, so he was not too surprised, but the two girls opened their mouths in surprise and couldn't close for a long time.

Originally, they thought that it must be pitch black inside, but when they really went inside, they found that the tree hole was not darker than the outside, although there could be no sun inside, but there were some colorful points of light floating in the high places, which looked like stars.

They really couldn't imagine how this strange tree hole space could be as high as the sky, what were the colorful stars, how could it be so bright but unreachable, and there was no stale atmosphere in the tree hole, and even what they saw in front of them was like a vast shijie.

Just when the two girls were in a daze, Xiao Yu had almost guessed in his heart that the Cangling Secret Realm was originally a different space parallel to the human world, and this tree hole was just a trick, maybe it could be said that it was a relatively clever phantom array, and this space was not a tree hole, but a different space that existed in the Cangling Secret Realm, and the tree hole was the entrance to this space.

There are still some benefits to liking to read books in ordinary times, such as the different space, which is not a secret that a monk in the Qi cultivation period can access at all, but there are many ancient books left by powerful immortal cultivators in ancient times who have mentioned different spaces.

There are even many monks who guess that the spiritual realm and the immortal realm are in a different space from the human realm, and as long as the monk can cultivate a strong enough space secret magic power, he can even reach the immortal world without cultivating to reach the realm of immortals, but if he wants to cultivate such a strong space secret magic power, it is even more difficult than cultivating to reach the realm of immortals, so this has become a kind of fantasy in the immortal world.

Xiao Yu had been in contact with the different space, so he had this guess about the weird tree hole in front of him, the more he thought about it, the more he felt that his idea was very reasonable, everything in front of him confirmed his guess, when he was outside, the ancient tree was not much tall or strong, so how could there be such a large space in the tree hole.

Now that he has an understanding of this tree hole space, he is no longer afraid, and pulls the little ninth sister who has not yet come back to his senses and walks to the depths of the tree hole, of course he didn't go to pull Ling Caiyan, but he knows that she will follow his footsteps.

The tree cave is also clean and abnormal, not even a single figure has been seen, there is not a single demon beast, occasionally you can see some traces of the soil left by the elixir after it was picked, it seems that the people who entered the tree cave first are far away from them, because Xiao Yu has been letting go of his divine sense to investigate, but there is no trace of those people.

It wasn't until they walked for a long time that they found some people, but these people were all dead, and these people looked like they were all disciples of the Demon Gate, and the first person who started them was also a disciple of the Demon Gate.

Because the deaths of these people are very tragic, but the corpses are still here and have not been swallowed, this can't be the monster beast's cause, the monster beast does not have the habit of not eating after killing someone, they generally do not pick and choose fat and thin.

Judging from the clothes of these Demon Sect disciples, they are not disciples of the same sect, almost all the disciples of the four Demon Dao Sects under the Heavenly Demon Sect can find out among them, what is going on, although he has long guessed that the four sects of the Demon Sect have sent disciples into the secret realm, but they do not search for elixirs and concentrates, but gather a large number of disciples to fight here, it seems that there must be some treasures here, which is why they are so crazy.

The four factions of the Demon Sect are all subordinate to the Heavenly Demon Sect, although they also have a lot of fights in private, and the Heavenly Demon Sect will not ask, after all, survival of the fittest is the way for the Demon Sect to cultivate disciples, but it is rare for a large number of disciples to get together and fight like now.

There are more than thirty corpses under their feet, and the fact that so many disciples can be gathered in such a short period of time shows that they have already arranged this matter in advance, and when they think of the map scroll they got from the ghost master, things are not so simple!

Disciples like Ghost Gongzi must be treasures in the sect, and they will not be sent to such a dangerous place as the secret realm to experience at all, if it is not driven by enough interests, how can those high-ranking bigwigs be willing to take such good seedlings to take risks.

The more he thought about it, the more he felt that things were not as simple as Dragon Phoenix Pavilion said, the disciples of the Demon Sect entered the secret realm not only for those elixirs, they must have a more important secret purpose.

After thinking about this, Xiao Yu didn't dare to slack off, it seemed that it was time to use the Hidden Spirit Pill.

It turned out that before entering the secret realm, Xiao Yu not only refined many spirit wines and pills to restore mana, but also refined a magical elixir - Hidden Spirit Pill.

He didn't know how to use the two bottles of Shadow Wolf King's blood in Xiao Yu's hand, and later when he was learning alchemy, he asked the master to know that the Shadow Wolf King's blood was the main medicine for refining the Hidden Spirit Pill, and other dispensing drugs were easy to get, and the biggest effect of this Shadow Wolf Pill was to be able to hide his body.

For immortal cultivators, the spell of stealth is not difficult to learn, and even some talismans such as invisibility talismans can achieve the effect of stealth, but these stealth methods cannot act when they are invisible, and the effect of stealth will be broken when they move, but the hidden spirit pill does not have such drawbacks, and the hidden spirit pill can also hide the breath to the greatest extent, so it is difficult for monks with a higher level of divine consciousness to find it.

In fact, Xiao Jiumei also had the Hidden Spirit Pill in her hand before, so she could be unharmed in the secret realm, and it was not until she met the ghost boy that she was able to break the feather for the first time.

Xiao Yu handed a few Hidden Spirit Pills to Ling Caiyan, she didn't even ask what this pill was, she swallowed it in her stomach, and immediately saw her body disappear little by little, but she could still touch herself when she reached out, and she knew that this pill was used for stealth.

Xiao Yu and Xiao Jiu Mei also took the Hidden Spirit Pill one after another, and then the three of them continued to walk forward, Xiao Yu took Xiao Jiu Mei's hand and walked in front, and Xiao Jiu Mei took Ling Caiyan's hand, Ling Caiyan walked in front of Zuihou, Xiao Yu and Xiao Jiu Mei were engrossed in observing the surrounding environment, only Ling Caiyan thought in his heart, "It would be great if Xiao Yu could also hold his hand!"

The more the three of them walked inside, the more corpses they came across the Demon Gate disciples, and there were almost hundreds of Demon Gate disciple corpses encountered along the way, and there were corpses constantly appearing in front of them, "What kind of treasure is it! What a large-scale melee it must be to make these Demon Gate disciples so crazy and so many disciples die!"

They stopped in front of the corpse of a demon disciple. He didn't move on, because the corpse of this Demon Sect disciple was still fresh, and the blood stains hadn't dried yet, indicating that he had just been killed not long ago, so they were not far from the real battlefield.

Xiao Yu still unfolded the meta-mystic technique of divine consciousness and silk to explore forward, and this time it didn't take long for him to see a chaotic scene, a group of demon sect monks were fighting together, the number of people was not to say that there were dozens of people, these people were completely crazy, and they couldn't see the enemy or the enemy at all, Xiao Yu saw with his own eyes that a disciple of the Heavenly Corpse Gate controlled the zombie and bit off the head of the same sect.

And there are not a few things that kill each other, Xiao Yu naturally won't disturb the melee of these demon disciples, he just hides to the side and watches the show, he knows that there will always be a time for him to make a move.
