In the depths of this trial ground, there is a special scene in front of Yun Tian, where the top of the original high-ceilinged trial ground suddenly narrows downward, and the stone walls on both sides are also tightening inward, and at the same time, the ground under his feet is also rising upward, and the entire trial ground is like forming a bell mouth here.

Yun Tian scanned it with his spiritual sense, there is no special threat around here, but the situation on this side is different from the safe zone, before in the safe zone, Yun Tian's spiritual sense can easily scan the outside of the stone wall, and can detect the scene on the periphery, and at this time at the end of this trial ground, although Yun Tian's spiritual sense can probe the past, but he can't see what is outside, his spiritual sense is like falling into a layer of gray mist, everything that can be detected by the spiritual sense is hazy.

However, the scene in the depths of this bell mouth, Yun Tian instead explored some, from here after the narrowed bell mouth, after extending inward for a distance, there is a slightly more open and spacious space, and this slightly open and spacious space is the same as the previous narrow passage, it seems that the previous open space is like a transition in the middle.

At this time, Yun Tian was not stunned at all, and continued to explore inward, and after he entered the narrow passage, Yun Tian immediately felt the difference between this place and the outside world. I only feel that the aura here is abundant, and the concentration is several times stronger than that outside. You must know that the spiritual energy in this super trial ground is already strong, and the spiritual power can be further strengthened here, which makes Yun Tian very surprised.

In fact, speaking of which, this kind of high-concentration aura is still much worse than the sea of consciousness space in the clouds, but if it is compared to some blessed land caves on the Xuanjie Continent, it is the gap between heaven and earth, if the general martial arts cultivators come here, I am afraid they will be crazy with excitement, and some people may not want to go out for the rest of their lives.

However, for Yun Tian, with the existence of the sea space, the situation in this horn mouth is pediatric for him, although he is also a little surprised, but it is far from the point of being shocked by it, and at this time, Yun Tian's state of mind is also becoming more and more peaceful.

Walking inward from the bell mouth, passing through the open transition area of the reeds, you will come to a passage, this passage is slightly wider than the previous bell mouth, but it has not changed much, continue to walk along this passage, and before you know it, you will reach the deepest part of the horn mouth.

Yun Tian tried to scan it with his spiritual sense, but what made him feel strange was that in the location that his spiritual sense could detect, there was a gray patch everywhere, and he couldn't see the specific situation inside at all.

However, when Yuntian walked all the way inward, after walking into a distance, he found that there was still an open space in front of him.

This is strange, Yun Tian had to cheer up twelve points of spirit, carefully probing the surrounding situation, at this time Yun Tian was also wondering in his heart, what is in the depths of this passage? Someone has said before that this passage is connected to the upper realm and the Xuan realm, but from the current view, he has walked to the deepest part of the trial ground, but except for a closed passage, there is nothing to be seen here, and the so-called upper realm is also nowhere to be seen.

Where is the legendary Upper Realm? Could it be the deepest part of this passage?

But Yun Tian couldn't believe that this was true, the upper realm was a world larger than the Xuan realm, how could it be connected through such a small passage? You must know that the upper realm is a high-level world, once it is connected to the lower world, then the areas connected to each other will immediately become unstable, and at the same time, if this instability is not controlled, it is likely to have even more terrible consequences, and may even make the upper realm face terrible destruction.

As soon as he thought of this, Yun Tian was also cold and upside down, thinking that it would not really be as he thought, the mysterious upper realm was not far ahead, and this is the passage to the upper realm, right?

Just when Yun Tian was thinking wildly, he only heard a crisp bird call, followed by the sound of flapping wings.

Yun Tian was stunned, this is obviously just a cave, where does the sound of birds come from?

Driven by curiosity, Yun Tian followed the birdsong, unconsciously passing through the previous area, and then directly reached the edge of the passage.

At this time, the sound of birds in front of them was clearer, the sound of flapping wings seemed to pass overhead, and there seemed to be a faint light in front of the cave.

Yun Tian groaned slightly, and did not stop under his feet, but walked straight forward, and the light in front of him became brighter and brighter, until a warm and warm light completely enveloped Yun Tian.

Finally came out of the passage, Yun Tian squinted his eyes to adjust to the light, and then raised his head and looked forward, but under this look, he was stunned.

Originally, Yun Tian thought that this was the exit, and since it was warm and warm outside, he should have walked out of the trial ground and came to the outside space, but when his eyes adapted to the light inside, when he saw the scene in front of him, Yun Tian couldn't help but be stunned.

Obviously, his judgment was completely wrong, because the scene presented in front of his eyes at this time completely subverted his imagination.

What Yun Tian saw in front of him now was a huge palace, the whole body of the palace was white, and it emitted a milky white light from the inside out, the area of the palace was very large, just from the front of Yun Tian's eyes, I am afraid it was several kilometers wide, and the depth could not be seen.

The sudden appearance of such a magnificent and magnificent palace in front of me is indeed shocking enough, especially since the width of this palace alone is several kilometers larger, and the visual and psychological shock is simply indescribable.

Yun Tian struggled to calm his emotions and probe his surroundings with his spiritual sense. Through the scans of his spiritual sense, Yun Tian roughly figured out the state of the surrounding environment.

This is actually a confined space, but the volume of the space is much larger than the previous transitional space, but that's it, that palace has also occupied the entire space, but the space on top of it is still relatively spacious.

In addition to this palace, there is an empty square all around, and the smooth white stone slabs are under your feet, and the clouds stand on it, and you feel the incomparable holiness and warmth around you, and the feeling of warmth makes people feel a little angry.

But Yun Tian was not confused by this superficial phenomenon, he continued to cheer up, carefully observing the surrounding situation, but whether it was looking with his eyes or scanning with his spiritual sense, there was nothing alive in the square outside the palace, but inside the palace, if there seemed to be spiritual power fluctuating, this may indicate that the real secret exists in the mysterious palace.
