This vast prison could never have been built by the Heavenly Sacrifice Old Man, but it could have existed for an extremely long time.

As they went deeper, Liu Qinghuan and Gui Bugui also found that this prison was not even more than one floor, but was built in layers from top to bottom, and there were no less than a thousand cells in the cells they passed through. Compared with the Yi Immortal Ren's repentance abyss back then, it was like a small witch, and it was not worth mentioning at all.

However, probably because they have not been used for too long, most of the cells have been abandoned, leaving only a few creepy or unrecognizable prison equipment, like evil spirits dormant in the shadows, ready to burst out and bite at any moment.

In the dark underground, only the Returning Tomorrow Eye Bead exuded a faint clear light, shining the shadows of a group of three.

Yuzun suddenly grabbed Liu Qinghuan's sleeve tightly, and his eyes widened: "What sound?"

Liu Qinghuan was pulled to a stop by her, and as soon as the footsteps of their walking disappeared, the entire underground corridor immediately fell into a dead silence.

The dead silence was like weight, filling every corner heavily, making people unconsciously even breathe a little lighter.

It's a pity that the two people who are breathing regard this dead silence as nothing, and they can't return to carry his thick-backed and heavy-edged treasure knife, and they are swaggering all the way, and Liu Qinghuan listens for a moment and pats Yuzun's hand comfortingly.

"Maybe it's something in the cell that's doing the trick again, it's fine, don't worry about it. ”

Yuzun still pulled his sleeves and joked: "Liu boy, don't you take pity on the jade, don't you see that the girl is afraid of the dark." ”

"She has been in the dark for an unknown number of 10,000 years, and she is afraid of anything, and she cannot be afraid of the dark. Liu Qinghuan said indifferently, glancing at Yuzun who was hiding behind her, but saw that she lowered her head, her expression was obviously nervous, and she was indeed very afraid.

This is strange, Yuzun can be regarded as an ignorant and fearless, even daring to break through the Great Destiny Technique, and he is also very bold along the way, why is he suddenly like this?

He asked, "What's wrong with you, do you feel something?"

"Hmm, hmm......" Yuzun shrunk his shoulders and looked around in a panic for a while, but his expression gradually became confused, and he said in a daze: "No, I heard something suddenly yell just now, but this moment...... Ah, are there any ghosts in this place?"

"Yo, you still know ghosts!" Gui Guigui laughed: "Sister, I'm afraid you didn't hear it wrong, why didn't we hear it? Moreover, a large prison like this is generally built to prevent the breeding of injustices and evil spirits, and it is cleaner than ordinary fairy cities, and it is impossible for ghosts to appear." ”

"And this?" Liu Qinghuan also heard this statement for the first time, and said: "No wonder, I didn't feel resentment along the way, and I thought it was because this place had been abandoned for too long." ”

"These are all necessary measures. "Just think about it, you don't know how many people or demons die in such places every day, if you don't melt away the deep resentment when they were imprisoned or when they died, I'm afraid it won't be long before the prison will become a ghost prison." ”

Yuzun was a little frightened, but in a blink of an eye, he forgot about it heartlessly, threw away the corner of Liu Qinghuan's clothes, and ran to the side of no return.

"Old man, how do you know so much, have you been imprisoned?"

"Eh, what are you talking about, who is the old man? Don't think that you are more tender, just pretend to be a little girl, you are older than me, hey, I have naturally been imprisoned, do you know the Stygian Mountain War Domain, think back then, the big prison in the Sin Qi Palace, that big, even bigger than here......"

Liu Qinghuan was a little speechless, and his tone of non-return was like being locked up as a matter of pride, and the more he talked about it, the more he was boundless. Moreover, he and Yuzun did not have the consciousness of being in some weird and terrifying ancient prison at all, and they were very comfortable along the way.

Liu Qinghuan followed behind the two, bragged for a while, and asked, "Senior, what do you think of this prison?"

He glanced back at him, his face was a little more cautious, and he muttered: "It's not simple, this place, I suspect that it's not just here, the bottomless abyss we entered, the entire abyss is very likely to be part of this huge prison." ”

Liu Qinghuan said: "The younger generation also has this guess, but there is a question that I can't figure out, why this prison was built here, or rather, whether it was originally built in the Immortal Mansion, or which overhaul built it later." ”

Gui Wugui shook his head and said: "It can't be built by one person, you must know that a prison of this scale is impossible to build with the strength of a single person." Just like the Stygian Mountain Battle Domain, there are only two of the same level so far, one is in the Nine Shades Sins Qi Palace, and the other is in the Qingying Heaven City, which consumes a large amount of spiritual materials and spirit stones every year to maintain its operation. ”

Liu Qinghuan's heart moved, and said, "You mean ......"

He smiled incomprehensibly: "This Immortal Mansion is probably different from what all of us expected at the beginning, and the identity of the owner of the Immortal Mansion is also very debatable!"

However, how it is debatable, they can't guess for a while based on what they have seen after entering the mansion, which is a later story.

The three of them chatted as they walked through the gloomy underground dungeon, they had already descended to the fifth floor, and the cells on this level were significantly more spacious than the upper floors, and the number of cells had decreased dramatically, and it took a long walk to meet one.

"Wow, come and see, what's in there!"

Yuzun first grabbed the wall and shouted and waved his hand, there was a small hole there, and the position was just at the height of the human eye.

"Don't get too close. Liu Qinghuan reminded in the back: "You are careful and dragged in again." ”

"It's okay, I've seen it, the cell confinement on this floor is basically still working, and it's not dangerous outside. "No return, followed by a shock!

Liu Qinghuan couldn't help but be curious, leaned up to take a look, and saw a hazy golden light in the dark cave, gathering together like a steaming cloud.

After a closer look, I found that it was a half-human-high spiritual grass shrouded in golden light, only to see its slender branches and leaves stretched out like an orchid, each leaf has two or three slender golden stripes, and in the middle is a long stem, and the golden fruits the size of an apricot eye are stacked one after another, and they grow on this long stem, hanging heavily like rice.

Liu Qinghuan narrowed his eyes slightly, thinking back to the classics he had read, he was suddenly shocked, and said in a lost voice: "Golden Vein Holy Fruit!"

Legend has it that as long as you swallow this fruit, there is a chance to give birth to a golden spirit vein in your body out of thin air, which will not interfere with your own meridians, but in the future, any magic magic power will not only bring your own sharp gold killing qi, but the power will also be increased by at least two or three percent!"

He rubbed his hands excitedly and laughed: "You can be regarded as having met a good thing! This ghost place can actually give birth to such a strange thing as the Golden Vein Holy Fruit? Look at this fruit, there are probably thousands of years, and it is already ripe to no longer ripen, and it can be picked!"

As he spoke, he immediately rolled up his sleeves and prepared to break the ban.

They entered this prison from the cave of the Heavenly Sacrifice Old Man, passing through countless cells, but they never touched the contents inside.

One is that most of those things are fierce and bloody torture tools, no matter how the two of them say it, they are also orthodox Taoist cultivators, and these magic weapons are not easy to operate, and the second is that because the two of them have extremely high vision, ordinary things can no longer enter their eyes.

Therefore, they are too lazy to make efforts not to provoke the bizarre killing moves and mechanisms in the prison cell.

However, when he encountered the Golden Vein Holy Fruit, there was a mountain of swords and a sea of fire in the prison cell, and it was impossible to let it go!

Liu Qinghuan fortunately didn't get carried away by the excitement, and hurriedly stopped: "Senior, wait, look at the ground, there seems to be something there!"

He stopped his hand, and saw a few dark golden bones scattered around the root of the Golden Vein Holy Fruit, and couldn't help but wonder: "It is said that the Golden Vein Holy Fruit was born in a place where the golden qi is extremely strong, if it weren't for the fact that there was a golden spirit beast imprisoned in this room, the spirit beast died, and this fruit was born with its power?"

"It's not impossible. Liu Qinghuan persuaded: "Do you think, how can anyone who can be imprisoned in this five-story cell be an ordinary spirit beast? If it is not an ordinary spirit beast, they all die in this cell, we should be more careful, and find out what killing moves are in it before it is too late." ”

Gui Wugui thought about it for a while, and pushed his hand away: "I know, you kid don't be verbose!

Liu Qinghuan also hoped that he would be more cautious, and when he saw this, he would no longer stop and retreat to the side.

Gui Gui unceremoniously picked up his big knife, crackled and slashed, and after a few violent sounds, the forbidden prohibition on the stone gate that had been in disrepair for a long time could not withstand his violence, and exploded a big hole!

In an instant, the golden energy danced wildly, and an intoxicating fragrance wafted in.

Liu Qinghuan couldn't help but be overjoyed, and as soon as he took a step forward, he saw Yuzun on his side suddenly grab the hem of his clothes and fall to the ground with a bang!

"Really?" he turned his head in surprise to see her trembling like chaff, so frightened that she was about to turn back into her original jade body.

"How are you?"

In the next moment, his pupils shrank sharply, and there seemed to be a roar in his ears that exploded suddenly, and his heart was shocked, and every bone in his body seemed to be trembling!

He raised his head with difficulty, and stood in place with a shocked face when he saw that he was not returning, and knew that he was not alone in feeling the terrible deterrent.

"Underground, there's something! It's coming out!"
