I am a living immortal.

This cave world is not without its merits, just like the precise and exquisite formation. In fact, there are formations in the outside world, but few people really study them. Or rather, too few people study them, resulting in the formations being useless.

The most sophisticated formations Su Mu had ever seen were the one on the Alliance Heaven ship, which instantly blocked air currents caused by high-speed travel, and the mountain-protecting formation he had used in the Fuling Sect. However, these two formations differed somewhat from the one he had just seen. The one on the Alliance Heaven ship was powerful but limited in function, while the mountain-protecting formation relied on the support of the Immortal Sect. Rather than a formation, it was more like a feng shui formation, built upon the wonders of the mountains and rivers. The main feature was the continuous wonders of the mountains and rivers, not the formation itself; the formation merely served a supporting role.

As for other formations, they are rare.

The large formation before him was completely different. Its main body was the formation, supplemented by smaller formations, nested and combined, like a machine.

To achieve this level, it is not something that can be accomplished by one or two people, or even a dozen people. It must require thousands of people who have persevered and accumulated experience over time.

Sure enough, completely different branches will appear in different environments.

Just as in the outside world, where the ceiling is high, cultivators constantly strive to reach new heights. Within the cave world, however, the ceiling may not be as high, so within this realm, one must refine and refine their skills. It's like the system of cultivating immortals. In Su Mu's view, the members of the Demonic Cult and the cultivators of the Qiyang Sect are at the same stage, yet they are divided into two distinct realms. While the differences between these realms may not be significant, they are still subdivided.

How to say it, maybe this system is more perfect and complete.

There's nothing wrong with this. After all, not everyone is gifted. Through a set of exercises, you can progress from the beginner level to the top, and the difference lies in the strength of your talent.

The outside world is completely different, mysterious and profound, and everything depends on enlightenment. If you can understand it, it means you have a predestined relationship, a talent, and are secretly compatible with this path; if you can't understand it, it means your understanding is not enough and you are not destined to follow this path.

Comparing the two, Su Mu discovered that the systems of each world changed with the changes in the environment. He seemed to have grasped something, but just as he was about to grasp it, it disappeared.

I wasn't discouraged.

Having this insight meant that this trip to the cave was worthwhile. As for what he could comprehend and see, Su Mu wasn't sure yet. But he still had plenty of time, so he could slowly observe and experience it.

It can be said that what they seek when they come to the cave is different.

Su Mu came to observe, to explore the path ahead; Shen Qiu was there to perfect his painted cave; Shen Long was drawn to the resources and rules within; and the old goat might have wanted to taste the grass from another world. In other words, he had no purpose; wherever Su Mu was, he would be there.

As for Lin Yuan and Yun Yue, this might be an interesting adventure.

In fact, it is better to separate. Even if we are together, everyone has their own purpose and will spontaneously separate.

Back to the formation in front of him. Su Mu kept looking at it, and the principle and structure of the formation unfolded bit by bit in his eyes, completely exposed.

As she observed, Su Mu gestured with her hands. The spiritual energy in her hands constantly shifted, from points to lines, from lines to shapes. This formation was a treasure trove. As she analyzed the principles, Su Mu was more amazed by its fascinating wisdom.

Before she knew it, Su Mu was a little fascinated.

The ingenious ideas of those who studied this formation. At first glance, this formation appears to be merely a means of concealing the surroundings and identifying those entering and leaving. But a closer look reveals much more. This formation is also a defensive formation that can increase the concentration of spiritual energy.

It combines multiple functions in one, it is exquisite, really exquisite.

If these wanted members of the demon sect can build such a formation, then what about the formations of those top sects?

After Su Mu studied this formation thoroughly, he had another destination in mind.

Then he entered the palace built on the cliff. These palaces were not simple. He slowly landed on the covered bridge, and his figure changed in a few steps.

Demonic energy appeared on his body. Although it was an imitation, it was no different from the real demonic energy. It was even more like demonic energy.

His azure robes had been replaced with dark-patterned black robes, and the hood was pulled up. He had a reason for being so brazen. I'd just heard that this was a branch of the Demonic Cult. Anyone who accepted demonic energy could come here, so no one recognized anyone else. It was like they were huddled together for warmth. After all, this world was dominated by the immortal path.

Su Mu walked on the corridor bridge and looked down.

The deep, dark valley seemed to possess some kind of magical power. He was surprised to find that the demonic energy he simulated was actually attracted to the things beneath the valley. If this demonic energy was not a simulation of his own spiritual energy and was absolutely under his control, he might have jumped down.

For a moment, Su Mu was a little amused and helpless. Perhaps imitating too closely was not a good thing.

“Do you feel an attraction?”

A familiar voice rang out from beside her ears. Su Mu looked up. It was fate, how could she run into him everywhere? This person was the one she had spoken to earlier.

The man smiled and said, "That's not a bad thing. It means that the quality of your demonic energy is very high, otherwise it would not be able to resonate with that thing."

"What's underneath is..." Su Mu's hoarse voice came from under the black cloak.

"The corpse of a demon, a real demon."

The man replied with a smile.

"A real demon? Does it still exist?"

"Of course there are. The Abyss has always existed, and demons have been constantly crawling out of it. Even if the top sects built walls outside the Abyss, they couldn't stop the demons from overflowing."

“Although most of them were kept outside the city walls.”

Su Mu nodded: "Thank you for your help. Excuse me, have you always been like this?"

"Huh? What's it like?" Chen Lie was a little confused.

"Have you always been so 'charitable' and willing to answer people's questions?" Su Mu's hoarse voice was filled with confusion. He lifted his leg and left, leaving Chen Lie bewildered. What did he mean?

Soon, he stopped caring. He knew that most of those who accepted demonic energy were forced to do so. Otherwise, they could become high-ranking immortals. Why would they harbor demonic energy and become a demon everyone hates? Emotional and mental problems—irritability, apathy, and irritability—were common. His case was truly rare.
