The two huge iron doors are a little thick and are pitch black all over, as if they are integrated into the entire mountain. An eternal lamp is lit on both sides, and the green fire has not been extinguished for thousands of years.

There are many demon reliefs on the iron gate, with green faces, fangs, horns on the head and scarlet eyes, like the Yaksha ghost in hell, extremely realistic and particularly creepy.

As soon as they arrived here, all three of them were powerful monks. When they saw these two dark gates, they felt so furious, as if they were the gates of hell that led to the Nine Netherworlds.

"A mere door, let me split it open!"

Luo Feng was holding a crescent sword the size of a palm in his hand, eager to try.

This crescent war knife is both a warrior and a magic weapon. Once it is infused with magic power, it can suddenly become larger and extremely sharp, cutting gold and iron, like cutting melons and vegetables.

"It's useless. A restriction was imposed on the black iron gate, which was connected with the entire mountain. Unless you can destroy the entire mountain, don't think about breaking the black iron gate." said the old man Jiujue.

"Yes, it's very difficult to break the door with brute force." Ye Tian nodded and said yes.

His divine thoughts, combined with the talent of earth, have searched the entire world all over. There are countless runes drawn on the black iron gate, not only connected with this mountain, but also connected with the twelve mountains, and even touched the floating mountain above the head. The restriction is so strong that at least the golden elixir has a glimmer of hope of breaking it. Often, even if it is nuclear weapons, it cannot be broken.

Especially the floating mountain above his head, it invisibly put a lot of pressure on Ye Tian, ​​like a mountain seal floating in the air, able to suppress it at any time, which is extremely terrifying.

"What should I do? Can it be cracked? How long will it take?" Luo Feng asked, very anxious.

At this time, Ye Tian suddenly walked over to a bright light next to the door. After looking at it for a while, he grabbed the light with both hands and turned it over and over again.

Suddenly, a surprising scene happened. The green fire was flowing like mercury, flowing over the two black iron gates, lit up runes, like spider webs, densely packed, spreading from all directions.

In the end, all the runes on the entire large iron door were lit up, and the green fire was like a ghost fire burning.

Click!

I heard a crisp sound, and the black iron gate cracked from the middle and opened to both sides.

In a moment, a large dark hole appeared in front of the three of them. Not only did the human eyes not see much deeper, but the spiritual thoughts would be suppressed.

Buzzing!

The murderous intent overflowed, making people creepy, as if a cave was connected to hell.

Ye Tian supported a light curtain, and hanged the Flip Seal above his head, and walked in step by step.

"I hope Elder Li is fine. Senior Jiujue, I'll go in and you can stay outside." Luo Feng said kindly to Elder Jiujue.

"Hmph!" Elder Jiujue snorted coldly, as if he felt that Luo Feng looked down on him. He was very dissatisfied. He quickly supported a blue protective energy and followed Ye Tian into the cave. He walked and said, "I want to see how the legendary Black Prison Heaven Prison is."

Luo Feng smiled bitterly and went in the third.

The cave is very deep, pitch black, winding down, not knowing where to lead.

The walls of the cave are also black rocks, and the murderous intent is filled with bursts of murderous intent. The deeper they go to the cave, the more murderous intent is.

Old Man Jiujue is an earth immortal, but it is not hindered. Ye Tian has the seal of protecting the body and turning the sky, but it is not hindered.

However, Luo Feng gradually couldn't bear it anymore and his body was trembling, so Ye Tian also enveloped him under the Fentian Seal.

clang!

A sword light suddenly pierced, illuminating the void, like a long rainbow.

"Be careful, there are mechanisms in the cave." Ye Tian reminded.

Bang!

While speaking, he pointed to a knife and slashed it out directly, cutting a small sword as big as a palm into several pieces.

Then he bounced his fingers and shot out a sharp finger, shattering a sword hole on the hole wall...

This little mechanism cannot do anything to the three of them, and they are in danger all the way.

After experiencing several miles deep in the narrow and closed cave, we finally arrived at a underground palace. Although it was much spacious, there was still only endless darkness, coldness, loneliness, no vitality, and no light.

If it is as legendary, this is an extinct place. Over time, it can dissolve the Taoist practices on people and reduce their magic power.

The underground palace is huge, silence like death, mottled rocks, dry and hard soil, as if no one has been here for a long time.

Soon a head was discovered by three people, like a human skull, but had a pair of horns.

The deeper I walked into the underground palace, the more corpses there were, there were thousands of human corpses, and there were skulls of many alien creatures. They were strangely shaped and huge in size. They all died for many years. The flesh and blood turned into ashes, leaving only white bones, and some even rotted.

It is not difficult to see that some of them are the corpses of the earth immortals, which are actually rotten.

You should know that the earth immortal treasure body can be immortal for thousands of years, and the precious bones can be used to make magic tools.

"This place is very strange. It can devour people's flesh and blood essence and resolve people's Taoism. I don't know how Elder Li is doing, so we have to find him quickly and leave here." Luo Feng was both shocked and anxious.

It is because the flesh and blood essence is squeezed that the earthly fairy treasure body will rot so easily, and even the bones cannot be preserved for a long time.

"If it is legendary, this is a cave of demon suppression, which was once used to suppress demons." Old man Jiujue said, and a deep shock could be seen in his pupils.

In Kunxu, there were once demons who devoured human blood essence and took the path of evil cultivation, and were able to compete with famous and upright sects for a time.

A battle between the main gate and the evil sect lasted for thousands of years.

Five hundred years ago, the last demon king of the demon clan was captured, indicating the complete defeat of the demon clan and henceforth withdrew from the stage of human history.

Those demon children who were captured were detained in a place called Demon Suppression Cave, which is here.

Not only the demons, but all the creatures imprisoned here, flesh and blood essence and Taoist practices are squeezed back to this world, of course, mainly the world of the Jiuli Divine Sect and the underground spiritual veins.

"The so-called famous and upright sects are just superficial, and their secret methods are even more dirty than evil sects." Old Man Jiujue said despised.

Rumble!

After walking for a while, suddenly a sound of thunder and thunder came from the front. The sound waves almost turned into substance, and the strong blood was spreading.

The underground cage, which was originally dead, suddenly had a trace of vitality because of the appearance of this sound, and a faint light also appeared.

Finally, the three of them came to the depths of the underground palace and saw an underground flame, which was burning from the ground lung fire, forming a magma molten pool. There were many metal cages around, and many were imprisoned in it.
