In the Death Swamp, Long Ao used the invisibility technique and then flew forward close to the swamp, and soon entered the core area of the Death Swamp.
Along the way, the immortals in the Death Swamp became more and more powerful. Long Ao encountered several immortals and passed through their areas with hidden traces. He knew that if he continued to move forward, he would definitely encounter emperor-level masters.
If he could pass through the Death Swamp safely, Long Ao didn't want to cause trouble along the way, because it would not be a wise move to expose his whereabouts here too much.
There was absolutely no reason why Immortal Emperor Yuanzong could track down the Immortal Desert. Long Ao even had some doubts about whether Demon Emperor Tianxing and others had betrayed him. After all, everything was possible.
"Hey, why haven't I met an emperor-level master yet?"
Long Ao has been moving forward at high speed, and has not encountered any danger for half a month, nor has he encountered an emperor-level master in the death swamp.
Of course, along the way, Long Ao also encountered many restrictions, all of which were passed directly by Feitian's powerful penetrating power, leaving almost no clues.
After flying for another three days, Long Ao found that he was almost out of the core area of the Death Swamp. Because of the immortals he encountered along the way, their cultivation levels almost dropped in a straight line.
While Long Ao was cautiously on guard, he suddenly discovered that he had reached the outskirts of the Death Swamp, because the cultivation base of the lords here had not reached the Immortal Stage at all, and the strongest ones were only at the late stage of Daluo Jinxian.
"The so-called dangerous place turns out to be just a legend. There are not even masters of emperor-level cultivation here. Compared with the Immortal Desert, it is not even the slightest bit worse."
Long Ao secretly thought in his heart that if he were in the Immortal Desert, even Long Ao would not be able to guarantee that he could pass safely, but in this Death Swamp, it felt very easy and he was about to pass.
After crossing the Death Swamp, we arrived at the Northern Immortal Realm, which is a wider area of the Immortal Realm. Because there are many dangerous places on the border, the Northern Immortal Realm is also the most mysterious place in the Immortal Realm.
Just when Long Ao was about to leave the border area of the Death Swamp, he suddenly found that the fog in front of him was so thick and terrifying that even his own eyesight could not see more than ten feet away, and if he used his immortal sense to detect it, he could not detect more than ten feet away.
A hundred feet range.
This shocked Long Ao, because with his cultivation in the middle stage of the Immortal Emperor, he could only detect a distance of a hundred feet, which was really unique.
The range of a hundred feet is not an absolute safe range for any immortal. Once you encounter a sneak attack by an immortal of the same level or a more powerful immortal, the consequences will be disastrous.
In the thick fog, Long Ao couldn't fly at full speed at all, because in this unknown area, there were dangers everywhere. If he was not careful, he could easily fall into the space restriction, and even encounter a surprise attack by an emperor-level master.
The further he went, Long Ao found that the scope of his immortal consciousness exploration was getting smaller and smaller, and in the end, it was not as big as what he could see.
Within a radius of ten feet, Long Ao can sense, but other than that, Long Ao can no longer detect. Under such circumstances, it is extremely difficult and challenging to move forward thousands of feet.
In the low altitude before, there was not even fog, and Long Ao's detection range was more than a thousand times larger than it is now. Therefore, when it was unable to detect farther places, it also meant that a crisis would ensue.
Long Ao was suspended in the air, hiding his figure as much as possible, and then slowly walked forward step by step. Every time he advanced a certain distance, the surrounding fog would become thicker.
"What on earth are these mists? Could they be an energy body?"
Thinking of this, Long Ao stopped and decided to try to see if he could swallow the energy in the mist.
When Long Ao appeared, a black flame ignited in his hand.
Long Ao secretly controlled the black flame and began to cover the controlled mist, and then controlled the mist in the flame. After that, Long Ao began to try to swallow the mist in the black flame.
However, when Long Ao used the Devouring Technique, he suddenly found that the mist in the flames jumped rapidly. After a while, the mist actually escaped from the black flames.
In addition, something happened that left Long Ao speechless. The black flame actually went out in the mist.
For an immortal with fire magic, the flames extinguished, which meant that a very terrible thing had happened. Long Ao found that his black flames could not swallow the energy of the mist in the air. In addition, the mist seemed to have spirituality.
It is not as simple as a pure energy body.
After the black flames extinguished, Long Ao found that part of the black flames disappeared into the mist. After being shrouded in the mist, the energy of these black flames also disappeared without a trace.
"These mist can actually swallow my black flames!"
Long Ao was shocked. This black flame was part of the dark secret book. It was a gift from a powerful person in the God Realm. Part of it was lost here.
As the black flames extinguished, the energy of the black flames merged into the mist, traveling farther and farther away. In the end, Long Ao was unable to detect it. He couldn't help but secretly rejoice that he did not use all the black flames, otherwise, he would have died.
It would be extremely tragic.
"Could this mist be energy controlled by humans? If so, the controller's cultivation is too powerful and must be very terrifying."
Long Ao began to understand why this place is also called a dangerous place. Perhaps the place close to the Immortal Desert is the safest area, and the closer to the Northern Immortal Realm, the truly dangerous place.
At this moment, Long Ao dares to continue to test the devouring effect. He wants to leave here immediately, but it is not in line with Long Ao's idea to turn back. After all, a good horse never turns back. Now that he has arrived here, the Northern Immortal Realm must be gone.
It's far away, so it's better to rush through this evil area in one go.
Long Ao once again wanted to use the invisibility technique, but suddenly found that the mist around his body suddenly changed, forming a circle of shining light that kept jumping.
"If I reach the late stage of Immortal Emperor cultivation, maybe I can be completely hidden here!"
Long Ao secretly complained in his heart. When the exploration range was less than ten feet, he was already in a very dangerous situation. If he was exposed in this terrifying area, he would undoubtedly be a living target and he might be attacked at any time.
Immortals attack in the mist.
"I hope the legends about this place are wrong, and I hope there are no emperor-level masters here!"
Long Ao comforted himself, and then started to move forward step by step. What made Long Ao even more helpless was that in the mist here, he could not absorb the energy in the mist. The situation here was even worse than that in the Juexian Desert.
The situation is even more difficult.
"No matter what, I must pass here!"
Long Ao had a determined look on his face, determined to continue moving forward and must penetrate this foggy and confusing land.
Whoosh!
Long Ao wanted to escape into the sky, but suddenly found that the effect was lost. He could not escape into the sky in this foggy land.
"No!"
Long Ao was shocked. He never expected that such a strange phenomenon would happen again, because in the past, he could escape into the sky even when the enemy was restrained, but his inability to do so this time was definitely not an accident.
When Long Ao tested it for the second time, he suddenly found a cold gust of wind blowing from behind. This gust of wind came so fast and fierce that it actually rotated and surrounded his body.
This whirlwind is similar to the tornado in the Immortal Desert, but it is more dangerous in this place where the vision is less than ten feet away.
Whoosh!
Long Ao wanted to teleport to avoid the black whirlwind behind him, but when he tried to teleport, he found that a powerful attraction firmly imprisoned his body.
"Can't teleport?"
Long Ao felt a little depressed. Such a place was simply too terrifying. No immortal would be willing to stay in such a place.
"Just pretend that you are not a 'good horse' and just take care of yourself!"
Long Ao thought mockingly in his heart, even if he wanted to exit this place, he would encounter a more powerful whirlwind. Once this whirlwind dances, it will be astonishingly powerful.
When Long Ao tried to spin against the wind, he found that the amount of energy consumed was far more than ten times what he expected. As a result, Long Ao was naturally unwilling to force a breakout.
"After so many years, someone finally broke into the fog of death. What a pity! What a pity! Immortal friends have powerful talents and cultivation, but they are helpless in this fog of death!"
A very magnetic voice came from all directions. This voice made Long Ao understand that he was not fighting against nature, but against an emperor-level powerhouse.
Long Ao was silent, and found that the black mist around him formed a whirlwind and was taking him away from the place. Soon he was in a thicker mist, which made Long Ao extremely helpless.
About a moment later, Long Ao found that the surrounding tornadoes had disappeared without a trace, and he was shrouded in a denser black mist. In this case, the range that Long Ao could detect and see was less than three feet.
.
Three feet is almost the perfect distance for close attacks. After exploring the blind spot of infinite proximity, Long Ao used the dragon scale armor. This time, the spell did not fail.
"No! I can no longer sense the direction."
Long Ao was shocked. After spinning just now, he had lost his original sense of direction. This meant that even if he tried his best to break out of this place, he might not be able to leave the Death Swamp.
"Third brother, don't underestimate the newcomers. If you can break into this place through the Immortal Desert, you are not an ordinary immortal after all!"
A woman's voice reminded, this voice was so cold that it made people feel extremely bloodthirsty.
"Second sister, please don't worry. In the fog of death, he can't see where we are at all, let alone detect us. Therefore, he is equivalent to a blind man, and we are in the dark. We can give him a shot at any time.
A fatal blow."
The man explained confidently that he was not worried about Long Ao escaping from the ground at all.
