As soon as they entered the stone gate, Han Li and the others passed through a dim passage and came to an extremely empty hall.

The hall was dimly lit, and there were dark yellow oil lamps hanging on the walls on both sides, and a milky white grease burned in them, and no smoke was produced, but a faint sweet smell permeated the air.

Han Li let out a sigh and looked at the other people, seeing that they were all relieved, he couldn't help but sigh in his heart.

It was not easy to escape from the joint efforts of two Da Luo-level monks, and if the prohibition was opened in a breath or two in the evening, they might all be wiped out.

Although it was safe for the time being, the tight strings in his heart did not relax at all.

They didn't know what kind of place this was, if it wasn't for the situation, he would never risk his life to enter this kind of place, in his opinion, the places that can be called forbidden places by a big clan mostly have some special meaning, either hiding some kind of exercise cheats or treasures, or sealing something.

Previously, the ghost wood and the Yin Ruin were so nervous about this place, it seemed that they were afraid of breaking the prohibition here, and it was speculated that it was mostly the second situation.

A few people didn't dare to stay in place for long, and immediately split up in the hall to investigate.

The floor of the entire hall is densely covered with layers of runes, criss-crossing and very complicated, and on the walls on both sides are carved two extremely long stone murals, the scenes on which are quite similar to those seen on the palace gate before, mostly bloody pictures of foreign beasts fighting.

"Something seems wrong, there's no road ahead, we're completely stuck here. Fox San walked quickly to the end of the hall, looked at it for a moment, and then turned back and said.

Han Li looked over and saw that at the end of the hall, there was no passage to the depths, and the entire wall was carved with a relief of a giant beast resembling a human shape, but it was the one on the right side of the palace.

However, at this time, the giant beast was no longer in the previous prostrate posture, but in an upright state, its legs were not human-like, but somewhat similar to red deer, with obvious bends at the knee joints, carved with huge black scales, and the appearance was wrapped around a thick circle of black evil qi.

I saw that he held his claws in one hand high, a cloud of pitch-black mist condensed in his palm, and in the other hand he held a very strange-shaped flame giant sword, making a roar in the sky, and a fierce aura with a primordial aura rushed to his face.

"We can break the ban on the space outside, and we definitely won't be able to resist them for long. Shi Chuankong looked worried, his eyes kept looking around, and he spoke.

"Don't worry, figure out what this place is. Han Li's gaze condensed slightly, and he spoke.

"It looks like a place of worship, look at the murals here. At this moment, the crying soul suddenly spoke.

Everyone hurriedly looked over, and saw that on the innermost position of the wall on the right, it was indeed carved with a scene similar to the ancient ancestors of the human world, worshipping the ancient gods.

It's just that the carved scene here is more grand and bloody, and the sacrifices used to sacrifice are thousands of gray world creatures, including all kinds of gray world demons with low spiritual awareness, as well as civilized races such as the Thorn Tuo tribe, all of which are driven into a huge pit in the shape of a "sea bowl".

Outside the pit, the giant beast carved on the wall leaned out and leaned out on the edge of the "sea bowl", grinning with a bloody mouth and a greedy and vicious face.

By comparing it with the Thorn Tuo people in the bowl, it can be seen that this beast is very large, at least a thousand feet in size.

After Han Li glanced at the huge pit in the shape of a "sea bowl", he frowned, took a few steps back, and looked towards a strange depression in the ground.

I saw that the chaotic rune lines on the ground seemed to be out of order, but in fact, they were all entangled and intertwined and gathered in this depression that was only a few zhang in size and deep under the ground.

"What's the matter, what did you find?" Bai Liyan had a lot of loss before, and after breathing for a while, he stepped forward and asked.

"Look at this depression, isn't it a bit like an open sea bowl, similar to the sacrificial pit on the mural?" Han Li said after a moment of silence.

"When you say this, it's really a little similar, it's countless times smaller, it seems that this is really a place of worship...... Is that thing on the wall?" Shi Chuankong looked at it carefully for a moment before speaking.

"I'm afraid that thing was sealed here, so this place is called a forbidden place by the Nine Ghost Clan. Han Li nodded and said.

"No wonder the Nine Phantom Clan is not allowed to fight here, what they are afraid of is breaking the seal here and releasing that thing. Fox San suddenly realized.

"Boom"

At this moment, the floor of the hall suddenly shook violently, and a roaring sound was heard from outside.

"They've already started breaking the ban...... Soul said.

"At this time, we have no way out, since their Nine Ghost Clan is afraid of this giant beast, we will find a way to release it, and maybe we can still earn a chance of life. Han Li pondered for a moment, then stared at him and said.

Hearing this, the crying soul's expression changed slightly, and a trace of hesitation obviously flashed in his eyes, and he didn't say anything after all.

"Boy, I advise you not to do this, I already remember what this thing is, once it is released, let alone dealing with the pursuers behind the ass, I am afraid that you will be the first to suffer. Seeing her expression, Han Li was about to speak, when Shi Qinghou's voice sounded in the sea of knowledge.

"Do you know what it is?" Han Li wondered.

"Kunhu, have you ever heard of it?" Shi Qinghou said.

"What is this?" Han Li was slightly stunned, a little unclear.

"Kunhu is a creature that has existed in the Gray Realm since the time of the primeval chaos, and it is said to be a monster condensed from the Yin Origin of the Gray Realm, and its strength is monstrous, and it is by no means invincible to man. Many races in the Gray Realm still retain the old custom of worshipping it. As for why it was sealed here by the Nine Shadows, I don't know. I said this as a kind reminder, and after all, you still have to make up your mind. After Shi Qinghou finished speaking, there was no more sound.

"Master......" Seeing that Han Li was a little distraught, Crying Soul hurriedly shouted.

The eyes of the others also looked at him, and it was clear that everyone had become accustomed to being guided by him and letting him make decisions.

"At the moment of life and death, I can't take care of much, no matter what is underneath, let's release it first. Han Li pondered for a moment, as if he had made up his mind.

Outside the hall, the roar became more and more intensive, and the ghost wood and the yin ruins seemed to be in a hurry, and the shots became heavier and heavier.

"This prohibition is very complicated, if it is forcibly broken, with our current combat strength, I am afraid that it will be too late, or try to see if it can be unlocked through the array?" Shi Chuankong frowned and said.

"Without further ado, go your separate ways. Han Li nodded, agreeing with his opinion.

So the people began to look for the formation and the pivot.

Purple light flashed in Han Li's eyes, and the Nine Demon Pupils moved towards the altar in front of him.

Under the Demon Pupil, all the details around the entire sacrificial pit were revealed.

After a while, he saw that on the seemingly flat altar, there were actually many earthworm-like lines, densely covered the entire countertop, the lines were messy, unorganized, and it didn't seem to be some unknown runes, but there was dirt and dirt hidden in its depression, and it was all like black silt.

And inside the sacrificial pit, there are also dense patterns, forming a strange pattern like a flame.

Han Li looked at it for a long time and realized that there was nothing unusual, then he shifted his gaze and continued to look at the surrounding murals.

The material on the stone wall is no different from the wall, and after looking at it for a long time, I still found nothing.

"What did you find?" asked Fox San as he walked back from a corner of the hall.

"There are some lines on the ground, but it looks intermittent and unorganized, it should only be used for decoration, not a magic circle prohibition. Shi Chuankong shook his head and said.

Han Li glanced up at the dome above and saw that there was a circle of circular runes larger than a circle, a total of seven layers, each layer had a string of dense runes engraved on it, and in the middle was an inverted black column.

"Look at it. Han Li's heart moved, and he reminded him.

When everyone heard this, they looked upward.

"This seems to be a spatial forbidden circle...... "Shi Chuankong's eyes lit up and said.

"Brother Shi, do you know this?" asked Hu San.

Shi Chuankong didn't speak, his brows twisted into pimples, as if he was in deep thought, and after a while, he slowly spoke:

"This prohibition is divided into two parts, heaven and earth, and from the overall layout, there are some similarities with our Demon Realm's Qiankun Forbidden Great Array. Judging from the pattern of the formation above, there is a lot of overlap with the space rune patterns recorded in the secret book of the gray realm magic circle that I checked before, and it should be a similar magic circle in the gray world. ”

"Is there anything we can learn from?" Han Li asked.

"I'm not sure, although there are some similarities, but the differences are also very obvious, there are a lot of fire-based patterns in this forbidden array, and I don't know what it is used for. Shi Chuankong hesitated.

As he spoke, there was another loud bang outside, and everyone's feet trembled.

"There's no time to guess, just try first. What if it doesn't work...... Let's wait for them to break through the formation and come in, and then fight to the death, and try to use their power to destroy the seal here. Han Li said calmly.

"Okay, then please listen to my dispatch for the time being and help set it up. Shi Chuankong nodded and said solemnly.

Everyone hurriedly responded, and began to take the pieces of Absorbing Ink Stones and the array plates from Shi Chuankong's hands, obeyed his command, and began to arrange them on the floor of the entire hall.

When the ground was covered with black stones, he directed the crowd to begin to inlay the top of the dome.

In addition to the simple instructions of the stone piercing the air and the footsteps of everyone moving quickly, there was only a roar from outside, and the atmosphere was extremely depressed.
