Yi Yun faintly heard a dull sound, like the sound of wind coming from a cave.

As Yi Yun continued to walk inward, the voice became clearer and clearer, and Yi Yun immediately realized that this didn't seem to be the sound of the wind.

Plop! Plop!

It was the sound of a heartbeat.

Yi Yun looked at the cave and suddenly felt that this mountain was like a living thing.

This discovery made Yi Yun a little creepy, and he hurriedly came to the side of the mountain wall and observed it carefully.

Accompanied by the heartbeat of the mountain, Yi Yun found that under the cover of those stalactites, there were white veins.

And these white veins are huge bones.

The more Yi Yun looked at it, the more frightened he felt, this entire cave was actually supported by a skeleton. This skeleton turned into this mountain after death, and its body became such a vast cave.

The bones of the giant beasts scattered here were nothing compared to the size of the skeleton.

They may all have been prey that were once devoured by the skeleton's predecessor, and in this case, perhaps the skeleton's stomach.

This skeleton has turned into a mountain after death, but walking in it, you can still hear the terrifying heartbeat.

If there is really a demon god buried here, then I am afraid it is this skeleton.

Yi Yun stood in front of the mountain wall and looked up at the snow-white bones, which shook slightly together with the sound of a heartbeat. A skeleton after death still carries the breath of life, which is simply incredible.

At this moment, a black shadow suddenly rushed out of the blood demon bone and pounced on the skeleton.

The shadow was extremely fast, almost like lightning.

And if Yi Yun found out about its attempt now, it would be too late to stop it.

But as soon as the black shadow rushed out of the distance of ten zhang, it suddenly let out a miserable scream, as if it had hit an invisible barrier, and suddenly bounced back heavily, and its figure suddenly became more illusory.

At the same time, there were also laws blocked around the black shadow, and the black shadow scurried left and right, but it kept colliding with these laws, continuously screaming, and the figure became more and more depressed.

"Yi Yun, what did you do to me?" the black shadow screamed.

Yi Yun looked at the black shadow and showed a hint of mockery: "This is indeed your true purpose. You can't get into the cave, so you want me to take you here. You were worried that if you talked about the cave directly, you would be suspicious of me at first, so you deliberately didn't mention it, but took me to the neighborhood and let me find out for myself. ”

"Yes, I can't get into the cave. I've done what I can do, and you're still not going to let me go?" asked the Dark Shadow angrily.

"You are not a blood demon bone at all, this mountain is transformed by a blood demon bone, if you are a blood demon bone, you can't even enter your own corpse?" Yi Yun asked with a sneer.

"You have long suspected me?" The black shadow's tone was gloomy, it was not strange that Yi Yun could guess that the white bones in this mountain wall were blood demon bones, but Yi Yun had obviously guarded against it a long time ago, and the hidden clues of this prohibition had not even been detected by itself, it had clearly been repeatedly probed.

"But you said that I am not a blood demon bone, where did this come from? The blood demon bone is in your hand, you can compare it with this skeleton. The shadow then said.

"No need for comparison, I'm not saying that this bone isn't part of the Blood Demon Bone. But you are not a god born from a blood demon bone, but a soul attached to this bone. You can attach it to the Blood Demon Bone, even if it's just a small part of the Blood Demon Bone, which means that your strength is not bad. Who are you?" Yi Yun asked.

The black shadow was silent for a moment, and Yi Yun had already guessed its roots.

Soon, facial features gradually appeared on the faceless face of the black shadow, a middle-aged man who looked very gloomy and had extremely long eyebrows.

"You're right, I was originally a martial artist, and I used to be a Seal Divine Monarch. Planted in the hands of a junior like you, count me unlucky. The middle-aged man's face showed a look of hatred.

After his accidental fall in the Demon God Tomb, only the Genshin escaped, and then found this small piece of bone, which may have fallen off the huge skeleton and washed out of the river of blood.

Upon discovering this small chunk, he immediately decided to attach himself to it. But if it weren't for the fact that he happened to be proficient in a devouring law, he would probably be devoured as soon as he attached, even if the primordial god was still there, but Lingzhi was afraid that it would have been chaotic a long time ago.

After successfully attaching this small bone, the middle-aged man sensed the location of the real blood demon bone through this bone.

This small piece of blood demon bone gave him great strength, allowing his remnant soul to have another way to cultivate, if he could get the real blood demon bone, his future strength would definitely surpass that of the former Seal Divine Monarch.

This is too tempting for him, in addition to absorbing essence blood to strengthen himself in the Demon God Tomb, his mind is full of real blood demon bones.

But with his abilities, he couldn't enter the cave at all.

Originally, he planned to use the sword Nameless to leave the Demon God Tomb temporarily, and then return to the Demon God Tomb to obtain the Blood Demon Bone after his strength grew.

But at this time, he fell into the hands of Yi Yun, and he knew that it would be impossible for Yi Yun to let him go after taking him away from the Demon God Tomb, so he could only lure Yi Yun here. Originally, he didn't expect Yi Yun to really be able to enter the cave, if Yi Yun couldn't get in, he would find a chance to escape into the river of blood, but Yi Yun actually came in.

The moment he entered the cave, the middle-aged man was so excited that he was almost exposed. He actually came to the blood demon bones like this, and it really didn't take any effort to get there.

But his excitement didn't last long, and he was slapped hard by Yi Yun and slapped back to the cruel reality.

"You used to be the Seal Divine Monarch? Yi Yun shook his head, this person fell in the Demon God Tomb, and no one even collected the corpse, it is estimated that he would have turned into white bones somewhere.

However, this person is also considered to be disabled, and there is only one Yuan Shen left, and he still wants to survive in the form of a skeleton.

"Miserable, if you can get the blood demon bone, what's the matter if you give up your physical body. The middle-aged man let out a miserable laugh, and his good future was shattered by Yi Yun.

"This blood demon bone is really good, thank you for leading the way, I will smile unceremoniously. As for you...... You should return your soul to your soul, and return to your earth. Yi Yun said with a smile.

When death came, the middle-aged man's face changed, and he hurriedly said: "Wait! I was originally from Daqian Shenzhou, if you can let me go, I can let Daqian Shenzhou come up with treasures that satisfy you, I still have exercises, and I can also tell you the place where I am buried......"

He tried to say as many benefits as possible, hoping to impress Yi Yun.

Although the loss of the blood demon bone made his heart feel like ashes, it was better than really turning into ashes.

"Daqian Shenzhou?" Listening to the middle-aged man's words, Yi Yun's face showed a strange look.

"Yes! I'm from Daqian Shenzhou. Seeing that there was finally something that interested Yi Yun, the middle-aged man nodded hurriedly.

"Oh, then do you know Lihuo?" Yi Yun asked.

"I naturally know him, he is my junior brother. Since you also know about the Fire God King, you should know that what I said is not a lie, as long as you take me to him, he will definitely pay you satisfied. The middle-aged man saw the dawn of hope, and Yi Yun's expression changed a little when he talked about leaving the fire, and he seemed to be very familiar with the fire god.

Yi Yun is not from Daqian Shenzhou, he can know the Fire God Monarch, which means that the Fire God Monarch has also come to the ancient battlefield this time. Maybe Yi Yun will have some scruples because of this, or maybe he has some ideas.

If he could get the help of a Seal Divine Monarch, Yi Yun would have a better chance of leaving his name on the ancient battlefield.

"Take you to him? Okay. Yi Yun's expression became more and more strange, and the fire of the evil god suddenly ignited in his hand.

The middle-aged man was shocked, from this small flame, he felt a terrible power, he looked at Yi Yun, and had a bad premonition: "Yi Yun, what do you mean by this?"

"What do you mean? Didn't you ask me to take you to Lihuo? Yi Yundao.

"Lihuo is dead?" The middle-aged man was stunned for a moment, and then looked at Yi Yun incredulously, "Could it be that you killed Lihuo......?" Ahh

Before the middle-aged man could finish speaking, he suddenly let out a terrible scream.

His soul was enveloped in the fire of the evil gods, and in the terrifying flames, his soul was burned little by little, and the pain was even more intense than when he sucked those warriors alive.

Gradually, the middle-aged man's soul body was completely burned in the fire of the evil god, and he relied on his soul body for I don't know how many years it remained, but in the end, it was burned out by a small flame in front of the blood demon bone that he most longed for.

After destroying the middle-aged man, the small blood demon bone in Yi Yun's hand suddenly lost its evil spirit, and gradually became decaying. But when Yi Yun lifted this blood demon bone in front of the mountain wall, this blood demon bone gradually resonated with this huge blood demon skeleton.

The aura of the blood demon bone began to change, and later there was a trace of raw breath.

Yi Yun held this blood demon bone, and was amazed in his heart, he had never seen such a powerful qi and blood power before.

Yi Yun didn't find any evil spirits in this cave, he speculated that it was because of the natural formation that no evil spirit could enter, so in this cave, the source of the blood river, there was no danger.

Yi Yun continued to walk inward along the veins of this bone, and the more he walked inside, the clearer the sound of his heartbeat became, and then he almost felt like he was standing in the heart of this bone.

And at this moment, Yi Yun suddenly saw a milky white pool appear in front of him.

The sound of a loud heartbeat came from the pool.

"It's ...... Divine milk chalcedony?" Yi Yun raised his head suddenly, and saw that above the cave, there were white stalactites, and a drop of chalcedony essence dripped into the pond along the stalactite......
