Lin Yu feet treading on flames, continued his relentless descent.
The flame was formed from his pure lightning power, and its power was not comparable to the ancient phoenix primordial fire of Fengchang Pavilion.
If those dark green insects on the rock wall tried to crawl onto Lin Yu and parasitize him, they would be burned by the flames first and turned into pitiful ashes.
Lin Yu knew that the creatures underground were afraid of fire and light, which was why they chose this method to enter the underground world.
This so-called underground world is like a bottomless pit.
After Lin Yu jumped in, he didn't land, maintaining the feeling of falling downwards.
Lin Yu could sense that there was no solid ground beneath his feet, nor any sharp rocks.
The surrounding mountain walls were not uneven; instead, they were perfectly smooth, like a flat surface.
Lin Yu didn't know how those dark green insects survived in this place, but it was obvious that even those dark green insects could only stay on such a smooth stone wall for a short while.
"It seems this isn't a gathering place for those dark green insects, but just a temporary stop," Lin Yu thought to himself as he continued walking.
The further you go down, the smoother the rock walls on both sides become.
The smooth rock face made it difficult for even the small, dark green insects to stay, so in the end, there weren't many of them left on the rock face.
"In other words, the closer you get to the Earth's core, the fewer of those dark green insects you see."
"Based on what we just saw, those dark green worms only live in the middle section of the crack."
Lin Yu came to a conclusion.
During this time, Lin Yu didn't think too much about it and just let his body continue to fall.
A raging fire burned on its body, deterring the dark green insects from even approaching.
Lin Yu believed that there must be a place to land within such a crack.
So he probed downwards, observing the rock walls on both sides, and also checking his feet for a suitable landing spot.
Unfortunately, the ground beneath Lin Yu's feet remained completely dark, much like the bottomless pit of this place.
After some time, the situation around Lin Yu remained unchanged.
"Does this place really have no boundaries?" Lin Yu was somewhat surprised.
In fact, before jumping into this underground world, Lin Yu had already used his mental power to explore the situation inside, and he had also observed the situation inside when he was above the crack.
However, Lin Yu guessed at the time that this place was not deep, and even if he jumped down from above, he would be able to fall back to the ground very quickly.
The depths of the underground world were the first place where Lin Yu felt acidic.
The second miscalculation was Lin Yu's estimation of those dark green insects.
Lin Yu originally thought that once he arrived in the underground world, it would be like arriving at the stronghold of dark green insects. However, to his surprise, there were no longer any dark green insects on the mountain walls around him.
As for those hound-like demonic beasts, they were nothing more than demonic beasts parasitized by tiny dark green insects.
The dark green insects are gone from this place, and naturally, the monstrous hound is no longer there.
The further Lin Yu went down, the stranger it felt. Why did this place seem like another vast space?
"I'm still falling. Something's wrong. This place looks like it's separate from the outside world."
"But if the underground and the surface are two different worlds, they should be completely different. Why do I feel a magnetic field when I'm up there?"
Lin Yu was even more puzzled.
According to He Buxian's previous description, after falling deep underground, the power in his body was completely wiped out by an inexplicable force, leaving nothing behind.
Lin Yu was initially surprised, thinking that this strange creature must be located in the underground world, which was why Lin Yu jumped down to investigate.
However, to his surprise, once he arrived in this underground world, everything around him was quite dull, just a repetitive cycle of the same dark scenes.
Moreover, Lin Yu's experience was completely different from He Buxian's; his power was not diminished at all, and his source technique power was not affected.
This has resulted in Lin Yu still not knowing what happened.
This world looks similar to the last time I came, but in reality, it seems that Ah Sheng has changed a lot over the years.
He Buxian might still be affected to some extent, but Lin Yu didn't feel anything unusual at all, not even the suppression of spiritual power.
The world deep underground remained pitch black, with only the faint light from the flames Lin Yu had lit.
From a distance, it looks like a solitary lamp, illuminating the world ahead.
Meanwhile, in a world far underground, He Buxian, the Fallen Black Phoenix, and Feng Changge were anxiously guarding the place where Lin Yu had left.
They watched helplessly as Lin Yu leaped down, his body ablaze with flames. Logically, those bright flames should have been very conspicuous in the darkness, at least enough for someone to see him at a glance.
However, unexpectedly, after Lin Yu jumped down, the flames descended at an extremely fast speed, and the speed of descent increased rapidly until they finally disappeared completely.
This only proves that the underground world is extremely deep, and even with the eyesight of several cultivators, it is still impossible to see the flames at once.
"I wonder how that guy is doing. Since he jumped, there hasn't been a sound." Feng Changge thought to himself.
"That's strange. I remember when I fell last time, I could still see the ground below, but this time I can't see it at all."
"Could it be that there are some differences between these cracks? Perhaps the crack that the Palace Master just jumped into is not the same one that I accidentally fell into last time?"
He Buxian spoke with a strange tone, as the current situation seemed quite different from what he had experienced last time.
"We don't know exactly what happened, but since you fell down there before, you should know more about the situation down there than we do."
Upon hearing this, the Fallen Black Phoenix frowned and said...
Even the fallen Dark Phoenix is completely baffled by the underground world.
