Yi Yun looked at these people, and his expression was also cold, he knew that although these people lived because of him, they were all selfish guys, always thinking about their own lives. If it weren't for their obedientness, Yi Yun would have driven them away a long time ago.

"Youru Fairy, the moon falls, I will give you this flag, and you will wait for me here for a while. There is a formation, which can hide your aura and not let the monsters find out. Yi Yundao.

"Brother Yi, do you still want to stay in this Demon God Tomb?" Nan Xuan Luoyue asked in surprise.

This demon god mound is so weird, Yi Yun has already obtained the blood demon bone, but he doesn't plan to leave?

"Yes, I still have some things to do. Yi Yun nodded.

"In that case, then Yi Gongzi can rest assured to go about his own business, and there is no need to worry about us. The fairy took the flag and said.

She had some vague guesses about what Yi Yun was going to do, and it was estimated that it was related to the blood demon bones, but this was Yi Yun's private matter, and she wouldn't ask more.

The rest of the people were a little disappointed when they heard that they couldn't leave, but they didn't dare to say much, they had already seen the power of Yi Yun's formation, if Yi Yun drove them out of the formation, they would be too late to cry.

"You maintain the formation well, and obey the orders of the fairy and the falling moon. Yi Yun glanced at them coldly and said.

"Yes, yes, Yi Gongzi don't worry. ”

"We must do our best, and we won't let the two fairies suffer. ”

The men hurriedly answered.

Seeing that everything had been arranged, Yi Yun turned around and left.

Everyone watched Yi Yun disappear into the Demon God Tomb, with different expressions and complicated hearts.

I don't know how many years no one dared to enter this demon god mound, this place must have hidden opportunities, but they don't have this strength, so they can only watch Yi Yun go to seek opportunities.

The demon god mound is full of blood, hiding all kinds of crises, and the more you go inside, the more intense the blood becomes, and you can barely see your fingers.

"Woo!" came the sound of crying and the sound of people talking from the blood.

Some voices even appeared behind Yi Yun.

"Help!

Yi Yun was unmoved and continued to walk forward.

A slender girl's figure let out a crying voice, and slowly approached from behind, opening her weak arms as if to hug Yi Yun.

"Ahh

A layer of gray mist suddenly appeared on Yi Yun's body, and as soon as the girl hit the black mist, she immediately let out a terrible scream like a night owl, revealing her face that had turned into white bones under her black hair, and flew back in fright, never daring to approach Yi Yun again.

"These are all warriors who died in the Demon God Tomb, resentful spirits who were polluted by blood and gas, and some of them were even born naturally here, they have the ability to bewitch the mind, and the warriors often encounter more than lucky. But it doesn't seem to work for you at all. Blood Demon Bone said.

The more it learned about Yi Yun's strength along the way, the more surprised it became, Sword Nameless was already extremely talented, but compared to Yi Yun, it was like a cloud and mud. Yi Yun's bone age is definitely no more than a hundred years old in its opinion, but whether it is combat power or willpower, it is extremely strong.

"Do you really want me to be hurt by these things? The next time you encounter something like this, you'd better tell me in advance what it is, rather than an afterthought. Otherwise, I'll refine you directly. Yi Yun said with a smile.

"No, you're too careful, I just don't think these things can help you. Blood Demon Bone said.

Yi Yun sneered, and the Blood Demon Bone stopped talking nonsense and continued to guide Yi Yun on the path.

Walking in the blood qi, he could hardly feel the change in distance and time, and even Yi Yun couldn't be sure how far he had gone later.

If a warrior gets lost here, I am afraid that he will eventually lose himself in endless loneliness and become a resentful spirit in the flesh.

At this moment, Yi Yun suddenly felt a strong bloody aura coming from front of him, and even made people feel like they had walked into a mountain of corpses in the Sea of Blood.

Yi Yun was horrified in his heart, he took a few steps forward, his heart jumped suddenly, and he stopped.

He looked at his feet, and as his blood qi was pushed away by the Hongmeng Destruction Domain, Yi Yun also saw where he was clearly.

It was a high cliff, Yi Yun was standing on the edge of the cliff, and below, there was a wide river.

The river flowed with extremely thick plasma, and a large number of white bones tumbled in it, both human and demonic. Standing next to the rolling river of blood, I couldn't hear a single sound, as if I was in a silent world, and an incomparably vast and lonely feeling suddenly hit.

Yi Yun stood quietly, and from this river of blood, he actually felt a sense of time.

Death is the law of time, and this river of blood flows here, which is also the law of time.

"It's amazing. Yi Yun thought that this river of blood should make people feel fear, but he felt peace here.

At this moment, waves suddenly appeared in the blood river, and an extremely dangerous and creepy feeling suddenly hit.

Yi Yun suddenly reined in the breath of his whole body, he heard a low ancient roar, and the waves in the blood river were churning, and huge waves were surging towards the distance.

As the waves surged past the edge of the cliff where Yi Yun was, Yi Yun sensed a gaze. A pair of huge eyes of indifference emerged from the river of blood and swept towards the cliff.

When swept by this gaze, Yi Yun only felt cold all over, as if he had been frozen into an ice cellar. He was ready to summon Kang Longding at any moment.

However, this gaze only swept past Yi Yun, and then disappeared in the blood river, and then the waves rolled into the distance, and soon the blood river regained its tranquility.

Yi Yun let out a long breath at this time, but as he looked at the river of blood in front of him, the previous sense of tranquility was gone. This river of blood is too dangerous.

"What was that just now?" Yi Yun asked.

"The river god of the river of blood. But what exactly, I can't say. Blood Demon Bone said.

Yi Yun snorted coldly, he felt that the blood demon bone should know, but he just didn't want to tell him.

However, for the existence of this kind of horror, Yi Yun adheres to the principle that people don't offend me, and I don't offend people, and he doesn't plan to explore it.

"Now is a good opportunity to collect blood spirit jade and cultivate in the Blood River, and the next time the river god appears again, it will be at least a dozen hours later. Blood Demon Bone reminded.

Yi Yun bypassed the cliff and walked some distance before coming to the Blood River. The blood river was also filled with blood-red mist, and the closer I got to it, the more I felt that the river was foggy and invisible.

At first glance, both sides of the Blood River are covered in white stones, but when you look closer, you can see that it is full of bones, most of which have been weathered due to the long-term erosion of the river, and look like stones.

Yi Yun slowly approached the Blood River, and soon found the Blood Spirit Jade on the bank.

The closer you get to the Blood River, the more the amount of Blood Spirit Jade will be, and the better the color.

It is conceivable that the entire riverbed of the Blood River may be covered with blood spirit jade.

Yi Yun continued to collect the spirit jade, but soon he found that the blood river had come to an end, and in front of him was a high mountain, and there was a huge hole in the mountain, and it was from this cave that the blood river gushed out.

Before Yi Yun reached the entrance of the cave, he smelled a bloody breath rushing towards his face, and the blood qi in it was dozens of times thicker than the blood river.

"This cave is the birthplace of the Blood River, I haven't even been to this place, if there is any chance for the Demon God Tomb, it must be here. Blood Demon Bone said.

Yi Yun sneered, this blood demon bone was not so kind to take the initiative to remind him of the fate, it obviously had some conspiracy, but if Yi Yun was even afraid of a bone conspiracy, or even gave up the opportunity because of this, then his martial arts would be in vain.

The entrance of this cave is full of blood, and at the same time, there are fluctuations in the law, which is a natural formation.

If you don't understand these rules, you won't be allowed to enter even if you come here, and this naturally formed formation is integrated with the surrounding environment, which is very difficult to break.

Yi Yun slowly comprehended and deduced at the door of the cave.

After a long time, Yi Yun finally understood the rules and began to play the seal, wanting to break the formation.

At this moment, he suddenly felt alarmed, immediately stopped his movements, and then carefully observed.

Seeing this, a layer of cold sweat suddenly broke out behind Yi Yun's back.

This natural formation turned out to be a formation within a formation, the first layer was transformed by the law, and the second layer was the condensation of qi and blood.

If you break the first layer alone, it will stimulate the killing array inside, and the killing array will directly crush people into plasma, merge into the blood river, and never be reborn. This natural formation, only dead things can pass through.

The blood water in the blood river, as well as the bones in the river, the blood spirit jade, these things can pass through the formation safely, but Yi Yun cannot.

Fortunately, Yi Yun saw the clue at the last moment, otherwise the consequences would be worrying.

Yi Yun carefully deduced several times, and after making sure that there were no other problems, he began to break the formation.

Two hours later, Yi Yun unlocked the law and entered the cave.

The cave is so vast that it seems to have become a world of its own. Hanging above the head are countless stalactites, and these stalactites are all made of blood plasma, and they are dripping with drops of blood.

Yi Yun walked along the river of blood towards the depths of the cave, and there was only the sound of blood dripping down the stalactites in his ears, and there was no sound other than that.

After approaching a distance, countless huge black shadows suddenly appeared in front of him.

Yi Yun was shocked, but he soon discovered that these black shadows were actually huge bones.

These bones are all demon beasts, but their size is huge, they must be terrifying monsters in their lifetime, even if they have been dead for I don't know how many years, their bones still exude a majestic aura, which is terrifying.

I don't know what happened here, but so many giant beasts died here, and they all gathered in such a cave after they died.

Yi Yun already had doubts about the legend of the place where the demon gods buried their bones.
