Long Yu quickly began to rely on the Nine Nether Seal to condense the special spatial force contained in the spiritual energy of the surrounding heaven and earth. This spatial force is purely the initial force that makes up the space of the Shenwu world. This kind of power must not exist in the world outside the sky.
Only by relying on the Nine Nether Seal can one feel this power. Even other powerful practitioners who have set foot on the secret realm of domination may not be able to feel the unique spatial power in the Shenwu world.
Through the Nine Nether Seal, Long Yu felt that the location of the Shenwu World Continent was very far "below" them, trillions of miles away. If it were not for space teleportation, it would take an unknown amount of time to go back. A few decades would not be a long time.
In fact, Long Yu did not determine the location of the Shenwu World by sensing the continent, but by sensing the Sea of Death. The Sea of Death surrounding the Shenwu World is one of the seven forbidden areas of the Shenwu World.
With only one percent of the Nine Nether Seal that Long Yu currently possesses, he can only vaguely sense the locations of the seven forbidden areas in this entire small world, but cannot sense the location of the Shenwu World Continent.
About half an hour later, Long Yu used the aura of the Nine Nether Mark to condense a small space channel in front of him. This space channel of course led to the direction of the Shenwu world.
However, Long Yu discovered that the special spatial force near where he was was not very strong, so the small spatial channel condensed could not be transmitted too far.
"I'm afraid it will take dozens of consecutive teleportations before we can return to the Shenwu World. On the way, we have to cross the sea of death that surrounds the Shenwu World."
Long Yu told his calculations to others, and of course Thunder Emperor, Flame Emperor and Sunset Dancer had no objection to it.
Now Long Yu has taken them out of the closed, desolate and silent space of Jiuyou Xuan Palace, so that they would not be trapped to death after a year. This has shown that Long Yu really knows something.
No matter how Long Yu knew it, Thunder Emperor and Flame Emperor didn't want to ask any more questions. They just wanted to go back. Besides, the experience of following Long Yu back would probably be very exciting!
After all, even for the Five Emperors, the only places they could reach before were the Shenwu World Continent, plus the two forbidden areas of the Jiuyou Xuan Palace and the Shenwu Realm Core.
But now, they have left these three places and found themselves in the endless void space of the Nine Nether Dragon Emperor's small world!
The small world of the Nine Nether Dragon Emperor can perhaps be simply referred to as the "Nine Nether Realm", so that it can be distinguished from the Shenwu World - the Nine Nether Realm is the entire small world, and the Shenwu World is the continent that breeds life and is surrounded by the sea of death. The Shenwu World is only a very small part of the Nine Nether Realm.
"gone!"
Long Yu laughed and took the lead to pass through the space channel he condensed. He only felt himself disappear from his original place in an instant, and the next moment he arrived at the destination of the transmission channel.
Originally, Long Yu thought that he would appear in a void of space, but when he raised his head and looked to the side, he was startled.
The entire Nine Netherworld is like a void universe!
In this cosmic void, it is not completely empty. Just like where Long Yu is now, he actually saw an air vortex emitting a dark light.
This air vortex looks similar to the Death Star vortex, one of the seven forbidden areas, but the color is different. If it weren't for the Nine Nether Mark, Long Yu wouldn't even be able to detect this dark air vortex.
Before Long Yu could make any plans, Thunder Emperor, Flame Emperor and Sunset Dancer had already passed through the space channel and caught up with Long Yu.
This time, the transmission through the space channel directly spanned a distance of billions of miles. If it were just relying on flying, it might take decades to reach the destination.
This is the benefit of comprehending the Nine Nether Seal.
"I'll go check ahead. Wait a moment."
After Long Yu finished talking to the three people, he flew directly towards the dark and dim air vortex. He felt that the air vortex seemed to contain a lot of power, and it was not the kind of violent and aggressive power, but a very gentle power, but with a slightly weird and gloomy aura.
The eerie and spooky atmosphere did not scare Long Yu away. After all, the Nine Nether Divine Texts that he had mastered were originally eerie and spooky, and he had long been accustomed to this kind of aura...
Thunder Emperor, Flame Emperor and Sunset Dancer, of course, did not dare to move rashly, for fear of accidentally touching some kind of restriction. They could only watch Long Yu fly forward, and his figure became smaller and smaller, and he almost disappeared from their sight.
When Long Yu was only the size of an ant in their eyes, he seemed to have finally stopped. The three of them felt that Long Yu seemed to have done something over there...
And now, Long Yu was of course absorbing the power from the vortex of air flow that emitted a dark glow. What surprised him was that the power contained in it was actually the aura of the Nine Nether Dragon Emperor!
If he didn't have the Nine Nether Mark on his body, he would probably be repelled by the air vortex once he approached it, let alone absorbing the aura of the Nine Nether Dragon Emperor.
But for Long Yu now, such an air vortex is definitely the best tonic!
"One percent..."
"Two percent..."
“Three percent!”
After more than an hour, Long Yu was overjoyed. He found that he had mastered more than 3% of the Nine Nether Seal from this air vortex!
Combined with the nearly 2% comprehension he had gained previously, Long Yu directly mastered 5% of the Nine Nether Seal. Now, his control over the entire Shenwu world has undoubtedly become more profound!
This also led to his continued improvement in combat effectiveness within the Nine Netherworld. Originally, he had mastered 1% of the Nine Netherworld Mark, which could increase his strength within the Nine Netherworld by 10%; now that he had mastered 5% of the Nine Netherworld Mark, he would be able to double his strength, and the effect was extremely terrifying!
Not only that, Long Yu found that he was now more sensitive to the aura detection in the entire Jiuyou Realm, but unfortunately, he still could not sense the existence of anything other than the seven forbidden areas.
"This air vortex emitting a dark glow contains the aura of the Nine Nether Dragon Emperor. It should be distributed throughout the void of the Nine Nether Realm. However, the air vortex is too small. It can only be felt if you are within a hundred miles of it... Trying to find this air vortex in the entire Nine Nether Realm is like looking for a needle in a haystack!"
After Long Yu absorbed the air vortex, he still felt a little unsatisfied. However, he knew that this kind of thing was hard to come by for him now. He also didn't know how much of the Nine Nether Seal he needed to master before he could sense the location of the air vortex in the void of the Nine Nether Realm
In other words, there is only one air vortex like this in the entire Nine Netherworld
No matter what, Long Yu couldn't stay to look for the air vortex now, because it was too difficult, even harder than finding a needle in a haystack. You have to know that the space of the entire Jiuyou Realm is billions of times vaster than the ocean, and it is not on the same level at all.
Long Yu absorbed the air vortex and started to walk back. He found that the speed of condensing the special spatial force around him was now faster than before. It only took a stick of incense time to condense a spatial channel like before, allowing them to continue moving towards the Shenwu World Continent.
Thunder Emperor and Flame Emperor were not angry or anything for having waited for Long Yu for such a long time. The Five Emperors had been practicing for hundreds of years, and even if they had nothing else, they did have patience.
After Long Yu returned, the four continued to move forward and stepped into the space channel that Long Yu had spent an incense stick of time to condense.
After Long Yu's second teleportation, he subconsciously looked for the existence of any air vortex in the surrounding space, but the result disappointed him.
As he had expected, that kind of air vortex was definitely not something that could be found just by looking for it. With Long Yu's current mastery of the Nine Nether Seal, he was unable to sense an air vortex that was too far away.
In the entire Nine Netherworld, the most clear thing to Long Yu is probably the seven forbidden areas.
Jiuyou Xuan Palace, Long Yu and the other four had just come out of that place, and were now moving away from that place. It was the nearest forbidden area to them, and they could reach it by teleporting twice.
The Sea of Death surrounds the entire Shenwu World Continent. It is not too far away from them now. It can be reached by about fifteen space channel transmissions.
The next relatively close forbidden area is the Shenwu Realm Core. In Long Yu's perception, the Shenwu Realm Core is a sphere condensed by the Nine Nether Divine Scriptures. Inside the sphere, there is almost endless power of the heart realm. This was a powerful magical power that the Nine Nether Dragon Emperor used to fight during his lifetime, using the power of the heart realm to explode and kill opponents. But now it has become a place where young geniuses organized by extraterrestrial forces go on adventures.
The location of the Shenwu Realm's nuclear forbidden area is at the lower left of where Long Yu and the others are now. The distance is about equivalent to fifty space channel transmissions. Compared with the Jiuyou Xuan Palace, the distance between the Shenwu Realm's core and the Shenwu World is almost three times farther.
The fourth relatively famous forbidden area is the Death Star Vortex, which is located "above" the heads of Long Yu and others, about 50,000 times the distance of space channel transmission.
The Death Star Swirl is definitely the most powerful of the Nine Nether Dragon Emperor's seven magical powers!
Even though the distance was so far, Long Yu could still feel the vortex of terrifying divine power contained in the vortex of the Death Star. Even a cultivator at the level of a Seven-Star Emperor would be instantly crushed to pieces if he broke into it.
With the Nine Nether Seal that Long Yu now possesses, he can condense two space transmission channels in one hour. Even if he wants to reach the location of the Death Star vortex, it will take seven or eight years!
It can be seen how vast the entire Nine Netherworld is.
The Death Star Vortex is the most powerful forbidden area, but it is also the farthest one. There are three other forbidden areas, which are the other three magical powers of the Nine Nether Dragon Emperor. He was not clear about it before, but after getting the Nine Nether Seal, he felt the existence of those three forbidden areas.
