The corpse of the Great Demon of the Seven Realms fell into the sea, attracting countless monsters to eat up, and the water demon that was still behind Chen Changsheng was also reduced by half, after all, no one wanted to end up like that Great Demon of the Seven Realms.

That flash of sword light crossed the barren sea, all the way forward.

Chen Changsheng didn't take the Seven Realms Great Demon to heart, he just had some doubts in his heart, whether there was a boundary between this heaven and earth.

When asked about the Black Tower, he heard the Black Tower say this.

"Yes, but if you say no, you may say no."

"It's just that this boundary is not original, and I don't know how to explain it......"

He thought for a moment and gave an ambiguous answer: "It may be artificially made, or it may be ......"

"It's made by heaven!"

"What do you mean?"

Heita just said, "You'll know when you see it." ”

Seeing this, Chen Changsheng didn't ask any more questions, he urged his mana to continue moving forward.

For several days, a few days and nights, most of the journey had passed, Chen Changsheng never stopped, but Heita never saw him tired, and he also had some bottom in his heart.

However, what surprised him even more was Chen Changsheng's mana.

It's as if it's inexhaustible, and it's really outrageous.

……

According to the Black Tower, there should be half a day's journey to that area.

But when Chen Changsheng raised his head, he saw that the distance seemed to be blocked by a high wall.

Chen Changsheng was a little shocked in his heart, "That's... What? ”

He hung above the barren sea, and in his gaze, hundreds of miles away, a towering wall occupied his view.

The high wall stretched to the left and right, with no end in sight.

Even though he had entered the Immortal Dao and seen many unknown things, when he saw the high wall, he couldn't help but sigh.

"It's shocking."

"When I first saw the wall, I thought it was incredible. ”

Chen Changsheng's eyes stared at the high wall, and he was a little speechless for a while.

He was going to go over and take a look.

Just as he was about to urge the fairy sword to step forward, he heard the black tower say: "Look and see, but don't go over." ”

"Behind the wall, you say?" Chen Changsheng asked.

Heita nodded, "There were many people who wanted to see what was hidden behind that wall, but without exception, none of them could come back, and no one knew whether they were dead or alive. ”

Chen Changsheng paused for a moment and muttered, "I know......"

After another half a day, the city wall gradually rose in front of Chen Changsheng's eyes, and everywhere he looked, it was covered by the high wall, like a barrier in the world, difficult to climb.

Chen Changsheng stood under the high wall, but when he raised his head, he couldn't see the highest end of the wall.

"How high is this wall?"

Chen Changsheng was curious, so he flew up.

As he gradually flew towards the heights, Chen Changsheng's gaze gradually saw the peak of the high wall.

He looked down again, but found that the barren sea was no longer visible in his eyes, and it was all obscured by stratus clouds.

"More than a thousand zhang ......"

If you really talk about it, it's not that high.

Chen Changsheng took a step and stood at the top of the city wall.

But when he looked behind the wall, he saw that there was a deep space in front of him, without light and sound, as if it were another world.

Now the barrier is in front of his eyes.

Chen Changsheng was silent for a long time, and said: "It's like a cage......

"Who knows." "But this wall must have a meaning for his existence, and as for what is behind the wall, it is not something we can care about." ”

Chen Changsheng thought about it for a while, he was a little curious about the world behind the wall, but the depth in front of him gave him a feeling of unease, and after thinking about it, he didn't rush in.

"Let's go."

Chen Changsheng said a word, and then turned around.

Heita was a little surprised when he heard this, and said, "You are a person who is not afraid of heaven and earth, and you actually leave so decisively?" ”

Chen Changsheng just said: "It's important to get down to business." ”

Seeing this, Heita didn't think much about it, so he said: "Thirty zhang below the barren sea is Yuxuan's tomb. ”

After hearing this, Chen Changsheng moved away from the high wall.

"Plop." With a bang, the waves splashed, and Chen Changsheng sank into the sea.

What he saw was a dark color.

The surrounding sounds were all cut off, and on the side, Chen Changsheng also saw the high wall standing under the sea, isolating the heavenly water.

He didn't care, but continued on.

When I was about ten zhang down, there was an invisible ravine in front of me.

"It's down there," said the Black Tower. ”

"How did you choose this kind of place?" Chen Changsheng frowned.

"It's supposed to be hidden," said Herita. ”

At first, Chen Changsheng still had some doubts in his heart, after all, the badger demon said that the location of this tomb was difficult to find, but when Chen Changsheng entered the deep ravine, he understood why the badger demon would say this.

There seemed to be a mist in the ravine, obscuring the view, and at the bottom was a layer of accumulated sand, I don't know how deep.

Heita said, "The gate of the dungeon is buried under this pile of mud and sand. ”

"Where exactly?"

"I don't know."

"I've only been here once, and I can't remember it now. ”

Chen Changsheng paused, he roughly estimated that the layer of sediment was tens of meters thick, if it was to be found, I don't know how long it would take.

Chen Changsheng stretched out his fingers and wiped them from the sight of his eyes.

A flash of golden light looked down, but there was no fluctuation.

"I can't see ......"

Chen Changsheng was a little surprised.

Heita said, "You have to look for it slowly." ”

Chen Changsheng pondered for a moment and grasped the sword.

"What are you doing?" Blacktower paused.

"Just cut it with a sword."

"This sediment is tens of meters thick, and you can see it when you cut it, but the fluctuations caused by this will definitely touch the rock walls on both sides, and if it collapses, you and I won't be able to get out at all!"

Heita became a little anxious, but then saw Chen Changsheng raise his sword.

"Boom! The sea and mountains are stable, and the sword qi sweeps away the dust! ”

Chen Changsheng swung his sword over, and at the same time, accompanied by an edict, the rock walls on both sides suddenly became stable.

The sword qi slashed across the mud and sand under his eyes, and with just a sword, he swept away the mud and sand in front of him.

At the same time, at the bottom, a stone gate also appeared in front of Chen Changsheng.

"Boom ......"

The rock wall in the ravine reacted suddenly to the fluctuations of the sword qi.

Chen Changsheng glanced at it and said, "Definitely!" ”

As soon as the edict was issued, the shaking seamount suddenly calmed down.

Seeing this scene, the Black Tower was a little sluggish.

"I've seen the art of edicts......

"But I've never seen anything like you."

With such a high gully and broken wall, it is decided?

This once again refreshed Heita's perception of Chen Changsheng.

How deep is this human practice?
