The sea of clouds is endless.

At this moment, eighteen dragons appeared in the sea of clouds, staring blankly at the dark mountain wall on the horizon. The walls of the mountain are thick and impregnable, exuding a strong aura that gives people a sense of impregnability......

"This is the legendary Boundary Mountain?"

At this time, some followers asked curiously, although they had heard of the boundary mountain wall, they had never seen it.

The boundary mountain wall, some people also call it the boundary wall mountain.

Because it is like a mountain, and like a wall, there is nothing wrong with calling it a mountain wall, and there is no wrong thing with calling it a wall mountain.

"Haha, Lao Tzu has finally come to Jieshan. ”

There was a little dragon king who roared, it had taken them nearly half a year to fly here from the Qingxu Temple in the Heavenly Realm. If it was an ordinary immortal god, he would not be able to fly here from the Qingxu Temple for a hundred years.

Because the flight speed of the little dragon king is too fast.

"Brothers, go. ”

The little dragon king roared, and then flew towards the boundary mountain.

However, although they could see the boundary mountain wall from a distance, they were extremely far away from the boundary mountain wall, and they couldn't fly to it for a while.

At this moment, Yan Qing was slightly surprised, he had seen Jiebi Mountain under the Demon Abyss of 100,000 Lian Mountains. But the Boundary Wall Mountain in front of him seemed to be stronger and more terrifying than the Boundary Wall Mountain under the Demon Abyss, and the aura it exuded was extremely oppressive, even trembling.

The boundary wall mountain in front of me is from heaven to earth, and I don't know how high it is.

At this time, even the eighteen dragons who were not afraid of the heavens and the earth felt extremely depressed in front of this huge boundary wall mountain that connected the heavens and the earth.

They are incomparably small in front of this boundary wall.

"Hey, Yan Qing, where is the boundary mountain pass?"

At this time, Megatron asked with some doubts, the boundary wall mountain that can be seen in front of him is so dense that even a fly can't fly in, where is there any boundary mountain pass.

Jieshan Pass, also known as Jiedaokou.

In fact, it all means the same thing, that is, in this impermeable boundary wall, there is a gap. And this opening is the opening of the Kyushu world, which can allow you to enter and exit the Kyushu world, and it is a channel to connect with the outside.

Of course, in the huge world of Kyushu, there must be more than one opening. However, this opening in Tiannan is the largest, and it is also the one that is truly connected to the outside world. Moreover, in every great world, there is a boundary mountain pass......

In this realm mountain pass, there is a heavy guard of the heavenly realm.

It is rumored that there are even countless powerful families who have guarded this mountain pass for generations, generation after generation......

At this time, Yan Qing frowned, as if their path had deviated. Then, he opened the skin scroll again, pondered it carefully, pointed to the right, and said, "Go to the right, and if you go all the way, you will be able to see the boundary mountain pass." ”

"It can't be wrong, right?" asked the little dragon king.

"Can't be wrong. Yan Qing said lightly, and then said to Lianshan Yi Zi behind him, "Tiannan is not here......"

"This isn't Tiannan?"

When Lianshan Yizi heard it, he was slightly surprised.

"Tiannan, there should be Tiannan in the broad sense and Tiannan in the narrow sense, in a broad sense, Tiannan is the south of the world in Kyushu, and here is Tiannan. However, in a narrow sense, Tiannan refers to the Tiannan where the Holy Emperor is buried......" Yan Qing thought for a while and said, although this can be regarded as Tiannan, it is not the Tiannan that is usually said.

The Tiannan that is usually referred to generally refers to the Tiannan where the Holy Emperor is buried......

"Since it's not here, where is Tiannan?"

At this time, Lianshan Yizi became a little curious, and even couldn't help but deduce, but the result of her deduction was that this was Tiannan. But she knew that this was not the Tiannan she usually talked about......

She couldn't even deduce it.

"Where?"

Yan Qing thought about it and couldn't help but look up at the sky.

But what was in the sky? He could only see, and he couldn't see the black pitch of the mountain wall at the top. Could it be that Tiannan is still on top of the boundary mountain?

"Childe, in that Tiannanzhong, will there be a way for you to repair your body?" At this time, Lianshan Yizi said suddenly.

Yan Qing's eyes lit up, then she frowned, shook her head and said, "I don't know." However, if I have the chance, I would love to go and see Tiannan and see the Holy Emperor who has incarnated as the Pillar of Heaven. After all, I've already been to the North......"

Little by little, time passed.

"Why haven't you seen it yet?Yan Qing, have you read it wrong?" Not long after, a little dragon king said again, very suspicious that Yan Qing was pointing the wrong way.

The other little dragon kings also grunted one by one, all saying that Yan Qing was pointing the wrong way.

"It's not here yet, what's the hurry?" Yan Qing was very calm, and didn't think that she was pointing the wrong way.

time, another two days passed.

"Fly up. ”

At this time, Yan Qing pointed to the boundary mountain wall and said.

Soon after, they felt a strong and incomparably dead air, and it seemed that in this rolling dead air, there were countless Kyushu human races fighting, which seemed very tragic.

"It's almost there. ”

A little dragon king said, feeling the terrifying murderous aura, and also a little frightened.

At this time, they were getting closer and closer to the billowing dead air, but the dead air was so thick that they couldn't see through it at all, and it turned into a huge sea of clouds in front of the boundary mountain wall. How many people do you have to die before that dead air can turn into a huge sea of clouds?

And, the closer they get, the more frightened they become.

The dozen or so followers felt the terrifying death, their bodies trembled slightly, and their heartbeats continued to accelerate. Jieshan Pass is the most tragic place in the entire Kyushu world, and I don't know how many people died here.

Soon after, eighteen dragons swept into the billowing air of death.

Whew—

Feeling this terrifying death, the eighteen-headed little dragon king couldn't help but roar. And the powerful aura emanating from their bodies forced this billowing dead qi away alive, and cut a way out of the sea of dead qi clouds.

At this time, they saw that there was a huge opening in the boundary wall mountain behind the sea of clouds. This opening is like a huge continent, incomparably huge......

That is the boundary mountain pass, the incomparably tragic boundary mountain pass.

"Kill, kill, kill, kill ......"

One by one, roars came from the mountain passes.

At this time, the sound of fighting rang out, and it seemed that the whole world was the sound of battle.

"Is this the Boundary Mountain Pass?" Yan Qing stood up from the dragon's back and quietly stared at the dark continent where the dead air was billowing. Moreover, on this dark continent, in that billowing dead air, he saw countless immortal wills.

They're roaring, they're screaming, they're roaring......

"Kill, kill, kill, kill......"

The sound of fighting was endless, like thunder ringing out.

At this time, the eighteen giants had already swept into that gap, which was the legendary Boundary Mountain Pass. It's just that this opening, which is huge, looks like a vast continent......

......
