"Jijijijijiji!"

The strange sound rang again. Li Feng turned his head and looked at the source of the sound. The empty white bones in front of him were already in a mess, full of cracks.

"The sound came from the front." Li Feng looked ahead. There was a passage on the bone wall in front. The sound that seemed to be a fierce and violent whistling was constantly coming from it.

Li Feng followed the sound and immediately walked towards it.

Suddenly, Li Feng raised his head suddenly and saw a huge head looking through the cracked mountain wall.

"Haha, it turns out you guy is hiding here!" Li Feng couldn't help laughing.

Xuan Mingshi ignored Li Feng at all, but looked at Li Feng secretly through the crack.

"Behind the crack, it should be the source of the underworld bones it guards!" He smiled, ignored the Xuanming Rat, holding the Earth Sword, and walked directly towards the passage where the sound came out.

When he entered the passage, Li Feng frowned. He felt that the power of the blood martial soul in his body was suppressed by a force of rules, but the white bone martial soul and the crazy god war energy could both activate.

The White Bone Martial Soul is originally the same as the environment here, and it is reasonable to be able to operate. And because during this period, Li Feng had already merged into his Mad God's Battle Aura through the dual cultivation of Yan Ruobing, which made his Mad God's Battle Aura also possess the same characteristics as the White Bone Martial Soul.

However, Li Feng clearly felt that the speed of the Crazy God's war energy was still not as fast as that of the outside world.

"Well, this should be the special aura formed by the source of the Nether Bone!" Li Feng said in his heart.

"Chichi!"

Flashes of strange energy fluctuations came, and Li Feng felt uncomfortable in his body.

"I want to see what the hell is there." Li Feng walked into the passage ahead with big strides.

The passage is not very long, but walking through the passage is also very empty.

At this moment, the mountain belly was like a gourd. The place where Li Feng and Xuan Mingshi fought before was the small end, and now the big end is the big end.

Connected through the central channel. There was a mysterious rat in the empty abdomen of the empty mountain before, but the slightly smaller empty abdomen in front of Li Feng was empty.

No treasure worth Li Feng is paying attention to

"Chichi!" For some reason, the sounds produced kept echoing.

"Huh?" Li Feng frowned, and he felt a burst of burning pain deep in his soul. This was simply an incredible thing.

"How could the undead attribute energy here be so rich?" Li Feng looked shocked. "I have never discovered that the undead attribute energy is so strong. The undead attribute energy here is at least hundreds of times more intense than the outside world sea.

"Such rich undead attribute energy should be as physical as it is. Why is it invisible and colorless?" Li Feng was shocked.

The undead energy here cannot be detected by the naked eye.

"I feel so strong that I feel breathless, how can I be invisible and colorless?" Li Feng endured his headache.

"Also, the undead attribute energy here is very violent and chaotic. It is precisely because of the undead attribute energy of the invisible heaven that the strange sound is produced. Moreover, the undead attribute energy of the wild heaven also makes my soul feel burning."

"If my soul was not protected by tower soul, I'm afraid I'll die in an instant when I came in here?" Li Feng looked at the surrounding space and saw a thick layer of powder at the entrance.

Seeing these powders, Li Feng felt his heart twitching violently. He had already thought of the source of these powders. I guess these powders were left behind by the remains of some peerless powerful men. In such an environment, even if people die, their bones cannot be kept for too long. The invisible force field will turn all the remains into powder.

When he came here, Li Feng felt that his internal energy had almost stopped operating completely. Even the white bone martial soul was the same.

Although the undead attribute energy here is extremely strong, Li Feng cannot absorb it at all.

"Isn't it true that Xuanming Rat lives in another cave."

Li Feng looked at the area where the Xuanming Rat was. The guy was hiding outside the cave entrance and looking at Li Feng with his two small eyes. It seemed very surprised. He didn't expect that Li Feng would not die in this situation.

Xuanming Rat has survived in this cave for more than 10,000 years. In this more than 10,000 years, many people can defeat it, because before, Xuanming Rat was still very weak. As time goes by, its strength is also growing continuously. However, Li Feng is the strongest among so many people who defeated it, because the Xuanming Rat is no longer the same as before.

Originally, Xuanmingshi thought that Li Feng would be killed immediately after entering the core space like the strong men in the past.

However, this time, Li Feng's performance disappointed the Xuanming Rat, and the human race had nothing to do.

How could he not die? Xuan Mingshi looked at Li Feng's figure, and his eyes showed doubts.

Here, there is a powerful rule power restriction. This rule power suppresses the undead attribute energy, and combined with the special rule power of the Qiankun Death Realm, all the energy is suppressed!

"roar!"

The Xuanming Rat was lying in the distance, staring at Li Feng with his eyes tightly, as if surprised that Li Feng could last for so long here. Xuanming Rat knew the benefits of this cave very well, so it was unwilling to leave the nest.

However, Xuanming Rat himself dared not come in the nest where Li Feng is now. After entering, his energy will be suppressed and his soul will be eroded. Over time, it will cause great harm to his strength.

In the past, the Emperor of the Shadow wanted to conquer the Xuanming Rat himself, but after the Emperor of the Shadow, the Emperor of the Shadow, immediately fled here.

Before the shadow emperor came in, his soul began to be eroded, which seemed very painful. Then the Xuanming Rat also plucked up the courage to attack the shadow emperor, and later the shadow emperor was beaten away by it.

This time, Xuanming Rat was originally planning to do this, but it found that there seemed to be no problem with this human race.

Li Feng continued to walk towards the depths of the cave. As he continued to deepen, he found that the power of the rules around him was getting stronger and stronger.

After Li Feng advanced dozens of miles, he finally discovered that there was a passage leading to the sky in the deepest part of this underground space.

At this time, Li Feng felt as if he was standing under a large chimney and looking upwards.

Li Feng saw the blue sky.

"This is the center of the Qiankun Realm Sea, right?" From here, it seems that the height of the Qiankun Realm Sea exceeds 100,000 meters.

On the surrounding mountain walls, Li Feng discovered many ancient secret patterns.

"This space was actually made by a human!" Li Feng discovered that these secret patterns were all sealed secret patterns. However, it should be that the years and months have passed, and the secret patterns of the seal gradually became invalid. This led to the dark fire inside the space being continuously emitted.

In the middle of the cave, Li Feng saw the space twisting. From the twisted space, Li Feng saw a white ball of light. Nine huge chains connected to the white ball of light, as if the white ball of light was locked here by these nine chains.

Seeing this scene, Li Feng's mind instantly saw the scene when he got the tower soul.

Back then, the tower soul was locked in chains.

"What is this?" Li Feng was very confused. He felt the terrifying rule power emitted from it. Although Li Feng could see this light ball, he knew that he was still a long way from this light ball.

Li Feng was sure that this white light ball should be one of the energy sources of the Qiankun Realm Sea, which seemed to be the source of the underworld bones he was looking for during this trip.

All the life bones and spiritual energy in the Qiankun Realm Sea escaping from the source of this ball of dark bones.

After a moment.

"Why is the undead energy of the sky around me rich?" Li Feng was a little surprised. "It seems that in this cave, the undead energy of the violent sky is centered on me."

"Hmm?" Li Feng found out from the corner of his eyes that the undead attribute energy around him actually crawled into his body.

After these undead energy drilled into Li Feng's dantian, they quickly rushed towards the black beads in Li Feng's dantian.

"Chichi!"

The black bead was crazily absorbing these undead attribute energy.

"How could this happen?" Li Feng was shocked. "How could the undead attribute energy cause the black beads to shine?" Li Feng felt very confused. He looked up at the source of the underworld bones in the center of the space and fell into deep thought.

Judging from the seals around, this seal has existed for at least tens of thousands of years, because the imperial battlefield was because of the failure of this seal, these sources of the underworld bones scattered to the outside world.

There are many peerless pattern arrays carved in the inner wall of the Qiankun Realm Sea. These pattern arrays form a powerful force of rules, suppressing the energy of other attributes. In this space, because of the source of the underworld bones, even the original energy of the undead attribute is suppressed.

"Who built this place?" Li Feng kept asking himself in his mind.

Venerable? It is impossible. Although Venerable is powerful, he does not have the ability to build such a huge building.

This should be a monument left over from ancient times.

Thinking of this, Li Feng felt relieved.

It is said that in ancient times, there were countless strong people in this world. It is reasonable to build such a powerful place in that era.

Li Feng began to think.
