In the dark space underground, piles of bones have been placed for a long time, and the dust on the ground has accumulated very thickly, and it looks like no one has been here for many years. The dead people in this place are probably specially brought by someone to bring food to someone or something.

As the accumulation of corpses became more and more blocked, Nie Yun walked into a larger space, and at this time, he felt a very strong force emanating from the surroundings, and the corpses suddenly disappeared, and this powerful force seemed to indicate that something huge was nearby.

Nie Yun stretched out his left hand, and above the flame lines, majestic flames emitted out, quickly illuminating most of the places in this space, and it was precisely because of this that Nie Yun saw the true face of this thing......

Countless chains were tied to it, and a black dragon, under the restraint of chains, could not move much. Nie Yun finally saw its true face, and only then did he understand why there were so many corpses.

"Tianlong, what is this?" Nie Yun's body trembled, even such a mentally powerful person still had an extremely strong sense of fear for this unknown thing.

"The Demon Abyss Black Dragon, an ancient divine beast, used to belong to our Divine Dragon Clan, but later it was excluded by our Divine Dragon Clan thousands of years ago due to its heavy anger. Tianlong sent a message in Nie Yun's brain, and when he mentioned the words Ancient Divine Beast, Nie Yun suddenly felt a creepy aura on his body.

"Oh my God, Ancient Divine Beast, this strength, can I beat it?" Nie Yun couldn't help but say in surprise to himself.

Roar!

Seeing that the moment Nie Yun had just erupted from the flames, this Demon Abyss Black Dragon had already awakened, and he thought it was a food delivery, and suddenly roared.

The sound of the dragon's roar resounded in this space, and Nie Yun, uncontrollably, took a few steps back, touching the tall pile of bones behind, which only increased the sense of fear. Of course, the biggest one must be this huge monster in front of you.

"Tianlong, is there any way I can defeat it?" Nie Yun hurriedly asked for help from Tianlong Dao.

"Find the Sword Spirit, if she can do it, then there may be a way to take you out, but you have to find a place where she can get out. Tianlong said, "The sword spirit can't beat him, even if I was in my heyday, I was only able to beat him just now." ”

Nie Yun understood what Tianlong meant, even if he didn't have a sword spirit, he could teleport out with his own corner of the reincarnation mirror, but the premise was that he had to find a place that could be separated from the outside world, and he couldn't teleport out if he didn't know how thick the surrounding walls were, because the enclosed space in the middle would definitely let him get stuck in it and not move.

After all, the black dragon is still restrained, his range of activities is limited, and it seems that he has been banned by someone, this guy's strength is not as terrifying as he imagined and Tianlong's back then, and now this guy only has the peak strength of the Emperor Realm, although this is enough to kill Nie Yun in seconds, but Nie Yun did not stop his escape because of this.

The black dragon was bound by countless face-to-face constraints, he could only rely on his dragon mouth to absorb the things around him and let them enter his mouth, and every time he absorbed Nie Yun, Nie Yun escaped from the place with an extremely fast body technique, and at the same time hurriedly explored the thickness of the surrounding walls through telekinesis.

However, no matter how powerful Nie Yun is, in a situation where he is single-minded and dual-minded, it is still quite difficult to face a dragon at the peak of the Emperor Realm who cannot act. This black dragon is obviously a stubborn guy, he saw Nie Yun dodging his absorption again and again, he became even more angry, and because of this, the frequency of his absorption increased a few points faster, and it was faster and faster, so that Nie Yun couldn't help but speed up his pace to dodge.

It's not a way to go on like this, after Nie Yun's frequency accelerated, the thoughts in his brain couldn't keep up with his own movements, so he simply stopped probing the surrounding walls and focused on dodging.

"Tianlong, is there any way to calm this guy down!" Nie Yun didn't care about communicating with his heart, and shouted out directly, in this space, there are only Tianlong, Demon Abyss Black Dragon, and the existence of three things, so there is no need to be afraid of being discovered.

"No, unless you can knock him unconscious~ But I advise you not to think about it, this is more difficult than ascending to the sky. "Tianlong is not belittling Nie Yun, this is indeed the truth, if you want to stun this black dragon at the peak of the Emperor Realm, with Nie Yun's strength, I am afraid that before he touches his head, he has already explained in front of him.

When the black dragon heard Nie Yun's words, it suddenly stopped.

"Celestial Dragon, which Celestial Dragon are you talking about?" the Demon Abyss Black Dragon suddenly asked. Nie Yun's eyes widened and looked at him, this was the first time Nie Yun had seen a real dragon head speak, this was very different from the kind of dragon imagined in the third dimension, the kind of long dragon in the legend, the dragon's feet were very small, and the body was extremely long, although it did not look like that in this space.

But this dragon has its own unique characteristics, this black dragon has a huge body, a pair of dragon wings, and above his dragon head, there is even the existence of a dragon crown, which is a symbol of the king, and this demon abyss black dragon should also be a very status existence before.

"Ancient Heavenly Dragon, what's wrong?" Nie Yun felt that there was a drama in this, it seemed that the Ancient Heavenly Dragon and him knew each other, these two dragons, could it be that there was any intersection between them?

"How could he be on you, is he dead too?" asked the Demon Abyss Black Dragon.

"Dead, the soul is in me. Nie Yun replied truthfully, if he didn't go along with it at this time, Nie Yun felt that he might die faster.

"It's really dead, but how are you here? No one in this place will come in by themselves, and whoever comes in is a death row prisoner who was thrown in by the people of the Five Elements Gate, and I am considered an executioner." The Demon Abyss Black Dragon no longer continued to suck Nie Yun, it seemed that he had already made some decisions, and during the conversation with Nie Yun, his voice became very vicissitudes, as if he remembered a lot of past events.

"I? I saw a demon flower in the Five Elements Gate, and secretly moved it, but I didn't expect it to fall here. Nie Yun was really speechless, inside this Five Elements Gate, not only is the design complicated, but also the mechanism is heavy, is this for their own people?

"Do you have a way to get the Celestial Dragon out now? I have something to say to him. The Demon Abyss Black Dragon said.

He was afraid of being noticed by the Divine Dragon Clan, so he hid and never appeared. Nie Yun explained.

"This is another space, which is separate from the Soul Heaven Realm, don't be afraid~"
