In the world of martial arts, there were only two types of people who could communicate with the Nether Realm. The first type was Earth-type martial artists.
This type of person possessed an extremely powerful Earth Elemental Perception. They would not enter the Nether Realm, but they could rely on the extremely strong intelligence of the Nether Metal to sense the existence of the Nether Realm from afar.
With this, Earth Elemental martial artists could use the Spirit Channeling Nether Metal from a long distance away, allowing their bodies to gradually possess the attributes of that metal.
Therefore, Earth Element martial artists did not directly obtain Nether Metal, but rather used their perception to obtain the same attributes.
The other kind of person was someone who directly entered the Nether Realm. This kind of person had to be at an extremely high realm. According to rumors, he had to be at least a Heavenly Tribulation Realm expert in order to survive in the Nether Realm.
For example, the five Nether Iron that Xiang Nan had obtained from the Bai Clan should be treasures that Heavenly Tribulation experts had brought back directly from the Nether Realm.
However, even so, the Nether Realm was still a dangerous place for Heavenly Tribulation Realm martial artists. It was said that a Heavenly Tribulation First Layer martial artist would almost die when entering the Nether Realm. After entering the Heavenly Tribulation Second Layer, there was a similar probability of death.
Only a ninth stage Heavenly Tribulation martial artist would have a 50-50 chance of entering. In other words, even if the Demon Emperor personally entered, his life and death would be mixed.
This was the reason why there was almost no Nether Metal in circulation on the market. It was countless times more expensive than magic crystals.
The reason why the Demon Emperor dared to throw Xiang Nan in was because he knew that Xiang Nan possessed the ability to jump through space. Bai He had already announced this point.
Although everyone didn't know that Xiang Nan's spatial jump was obtained from the Void Divine Lightning, this ability could at least allow Xiang Nan to survive in the void without dying in the endless void before he could reach the Nether Realm entrance.
At the same time, the Demon Emperor also gave Xiang Nan a second choice. That was, if Xiang Nan refused the Demon Emperor's request, he could return.
Xiang Nan turned around and saw a long black line behind him. One end of the long line was connected to him, and the other end was connected to the distant Black Sharp Demon Cave.
If Xiang Nan went back on his word, he would be able to grab the black line and fly back. However, once he decided to enter the Nether Realm, the black line would break.
The most terrifying consequence was that the Demon Emperor could not directly release another black line to pull Xiang Nan back from the Nether Realm.
In other words, after Xiang Nan entered the Nether Realm, he would face two near-death dilemmas. The first dilemma came from the Nether Realm itself, and the second dilemma was how he could return to the human world.
"Kid Xiang Nan, what do you think?" The eight-eyed snake said, "The choice the Demon Emperor gave you is very simple and crude."
Xiang Nan said, "Now all the martial artists in the world know what I'm capable of. If I don't go to the Nether Realm to strengthen my strength, even if I return to the human world now, I'm afraid I'll die. I can only go to the Nether Realm to fight."
"Worst of all, I also have the ability to revive by bathing in fire. It shouldn't be that easy to die."
During the long voyage, Xiang Nan felt boundless loneliness.
He felt as if he was in the boundless universe, but what was even more tragic was that this universe did not even exist with stars.
Black! A completely black world!
Without any reference, Xiang Nan even doubted for a few times whether he was motionless or not.
There was no concept of time here. Xiang Nan could only keep talking to the snake. He could only use the number of words he spoke as a language hourglass to roughly calculate how much time he had spent.
Xiang Nan maintained a constant drifting speed in this silent and intangible void.
According to his own estimation of time, he had almost gone through a day or two compared to the human world.
Right in front of him, a huge void vortex appeared.
There was no concept of upper, lower, left, and right here. The front was relative to Xiang Nan's current face.
The void vortex appeared very strange. Xiang Nan discovered that he could only see the vortex from this particular angle.
If his gaze was slightly tilted, the void vortex would suddenly disappear!
So much so that Xiang Nan almost couldn't discover the existence of the vortex.
"What a peculiar thing." At this moment, Xiang Nan's curiosity was more than fear. He kept looking at the approaching vortex of nothingness and felt that there was actually such a wondrous thing under the heavens.
The vortex was too large, and could be measured to be a hundred meters in diameter. However, after Xiang Nan flew out for a while, he discovered that it had turned into a thousand meters in diameter.
If he flew further, he would reach a diameter of ten thousand meters. If he continued to fly, he would be able to cover his entire field of vision, and he would no longer be able to see the boundary of the vortex.
You can imagine that when you look at it, it is an existence that occupies the limit of your vision. When you tilt your head slightly, it disappears! This situation was so bizarre that it could not be explained by common sense.
"This is the Nether Realm, right?" Big Snake said in a low voice, "Kid Xiang Nan, if you go back on your word now, you still have a chance to go back. Otherwise, you might not be able to return."
Xiang Nan gritted his teeth and said, "You still don't know my temper? You must do what I've decided!"
Slowly, Xiang Nan was about to come into contact with the void vortex, but he still didn't feel the slightest bit of attraction.
Until he passed through the vortex, he only felt that everything in front of him had turned pitch black again, and nothing could be seen anymore.
It's getting dark again.
However, strangely enough, Xiang Nan felt that he was no longer advancing, because he felt as if his feet were stepping on the ground.
However, when he looked around, it was still pitch black, black without a bottom.
"Am I … in the Nether Realm?" Xiang Nan curiously reached out and touched the ground. The feeling was very strange. It was very similar to the land of the human world.
However, his eyes still couldn't see anything, and there was no air that could let him breathe.
He could still feel a feeling, as if he was experiencing something in the void. He couldn't breathe, and his chest was filled with a very strong feeling. It was as if he was about to fill his body to the point of being torn apart by the endless void.
"There's no light …"
The eight-eyed serpent suddenly said, "Could it be that the Nether Realm was directly exposed to the void?"
Xiang Nan suddenly realized, "In that case, I have entered the Nether Realm now. However, there is no air or atmosphere here. It is exposed to the void, so it cannot see the starry sky, nor can it receive any light."
As he spoke, Xiang Nan raised his right hand and drew out a gentle ray of sunlight.
Because this place had never been illuminated by sunlight, and there was no sun energy in the void, Xiang Nan could only convert his Dipper Qi into sun energy to illuminate his field of vision.
As expected, under the light, the surroundings suddenly lit up.
"I saw it!"
Xiang Nan lowered his head in surprise. Sure enough, there was a strange land beneath his feet. It was a bit like sand, but it was different from sand.
He twisted a small dot in his hand and discovered that it was made up of countless tiny crystals that looked like sand.
"Kid Xiang Nan, raise your head! Quick!!"
Suddenly, the words of the Eight-eyed Snake exploded in Xiang Nan's heart.
The moment Xiang Nan raised his head, he was frightened by what he saw, causing a chill to soar above his head.
