Chapter 1524 Mysterious Voice

The space between the split branches of the blood tree was just big enough to accommodate Master Shura, Xiao Yun and others, and after they were stuffed in, the branches of the blood tree returned to their original state.

On the surface, the blood tree is still the same as before, not much has changed, but Xiao Yun and others can see the outside world.

The sky changed in the ancient battlefield, and black mist poured out from the depths. This black mist contained the power to cover the sky and the sun. All seven levels of space were completely crushed by the black mist.

Xiao Yun and others were shocked. The black fog in the sky felt much stronger than the blood tree.

Moreover, the black fog in the sky rolled in as if it had intelligence, but when it approached the blood tree, the black fog in the sky stopped.

The black fog in the sky seemed to be looking for something.

Xiao Yun and others couldn't help but hold their breath. Could they be looking for themselves and others?

"It is indeed looking for you, but you don't have to worry. You are in my body, and it doesn't dare to do anything." The blood tree said slowly.

"Senior, what kind of creature is it?" Xiao Yun couldn't help but ask.

"You have so many problems, kid."

The blood tree's tone was displeased, but it still said: "It is one of the alien creatures produced in this ancient battlefield. As for what kind of creature it is, I don't know. Anyway, over the past million years, it has often searched for other creatures to devour. . If you had encountered it just now, you would have been swallowed by it by now."

"Thank you, senior, for saving me." Xiao Yun quickly thanked him.

"If you are grateful, help me find some dark soil. This is much more affordable than saying thank you with your mouth." The blood tree said casually.

"Then when I go to the outside world, I will definitely pay attention to whether there is dark soil." Xiao Yun quickly replied, this is a good opportunity to make friends with the blood tree.

If you find the dark soil in the future, you can bring it into it. Not only can you make friends with the blood tree, but you can also exchange it for the blood god fruit.

"You are quite clever, kid."

The blood tree has lived for millions of years, and its spiritual intelligence is so strong that it can naturally see Xiao Yun's thoughts at a glance, but it does not reject it because it is beneficial to both parties.

The black mist in the sky seemed to realize that the blood tree was protecting Xiao Yun and others. After staying for a while, it had no choice but to turn around and leave.

Rolling black mist breaks through the sky, and it is time to return along the road.

Suddenly, a shrill scream came from the depths of the ancient battlefield. This scream directly caused the seventh layer of space to explode, and terrifying sound waves were transmitted.

The black mist that was about to return suddenly rushed towards the blood tree.

At this time, the blood tree began to tremble violently.

Xiao Yun and others were shocked to find that streaks of blood emerged from the dense roots of the blood tree. These blood glows were the power accumulated by the blood tree through hard work and were its savings over many years.

Blood light surged out wildly, covering the whole body of the blood tree, turning into an extremely powerful defense.

The black mist rushed over, and it wanted to rush behind the blood tree, but the many blood lights released by the blood tree formed a giant net, blocking it in front.

The black fog in the sky seemed to be furious, because the blood tree used it as a shield to resist it, and it quickly crashed into the blood light.

However, the blood glow is the power accumulated by the blood tree for many years, and the black fog in the sky cannot destroy these blood glows in a short time.

The sound waves advance layer by layer, seemingly slowly, but actually they are incredibly fast.

In the blink of an eye, he had arrived in front of the blood tree.

The moment the black fog in the sky touched the sound wave, it quickly melted, and in just a split second, it completely disappeared.

Xiao Yun and others were shocked when they saw this scene.

Only the Master of Shura Academy had a deep expression, because she had seen such signs before, and that voice came from the depths a hundred years ago. If the blood tree hadn't saved her, she would have been killed long ago.

The remaining sound wave power fell on the blood tree, and the blood light of the blood tree was extinguished one after another, and more than 90% of the branches and leaves that were hundreds of miles wide were directly shattered.

The fallen branches and leaves sank into the ground, and the blood tree absorbed these branches and leaves into its body again and accumulated strength again, but now its appearance is not very good-looking, with only the trunk remaining.

"What kind of creature is making this sound..." Xie Dao trembled.

Although the blood tree withstood the power of all the sound waves, they inside the blood tree could still feel the terror of the sound waves.

If the blood tree hadn't resisted, I'm afraid they would all have been killed.

"I don't know, it has existed since millions of years ago." Blood Tree shook his head and said.

Many alien creatures were born in this ancient battlefield, and each alien creature will follow the underlying rules, that is, wherever it is born, it will stay there.

Especially the alien creatures born in the periphery cannot step into the depths of the ancient battlefield at will, otherwise even the strongest alien creatures may not be able to walk out of the depths of the ancient battlefield alive.

Since ancient times, many alien creatures have entered the depths. Blood Tree knows six of them, but they have never come out.

Although curious about the depths of the ancient battlefield, the blood tree never thought of stepping into it because it knew the consequences of stepping into the depths of the ancient battlefield.

Even the Blood Tree couldn't tell what kind of creature was emitting the terrifying sound waves, and the Master of the Shura Academy was even less clear.

"Senior, has this sound been heard before?" Xiao Yun asked curiously.

"It used to happen once every hundreds of years, but in recent years the frequency has become higher and higher, and it will happen once every hundred years or so." Blood Tree said.

"Once in a hundred years...why does it do this?" Xiao Yun looked puzzled.

"I don't know, but it has been around to this day anyway. Little guy, there are some things that you don't need to explore so much, especially dangerous things. That mysterious creature is very scary. The sound waves emitted from the depths of the ancient battlefield can kill us. "

The blood tree said slowly: "If you go to investigate, you will definitely die. Anyway, its name is its business and has nothing to do with us."

"I'm just curious."

Xiao Yun replied, then looked at the blood tree, "Senior, this ancient battlefield is so dangerous, why don't you come out with us?"

Hearing these words, Master Shura couldn't help but take a second look at Xiao Yun. As the Master of Shura, she was naturally extremely smart, so how could she not understand the meaning of Xiao Yun's words.

Xiao Yun obviously planned to let Xue Shu go out to guard Shura Battle Academy.

With such a powerful blood tree guarding the Shura Battle Academy, who would dare to provoke it?

"This little girl wanted to lure me out a hundred years ago. I didn't expect that a hundred years later, the person she brought in would try to lure me out again." The blood tree snorted, not knowing whether it was angry. Still not angry.

"Senior is different from other alien creatures. Its roots are in the ancient battlefield. Once it leaves the ancient battlefield, it will die." Master Shura explained to Xiao Yun.

After hearing the words of Master Shura, Xiao Yun couldn't help but look regretful.

But think about it, the environment of this ancient battlefield is special, and the alien creatures bred will naturally be special. If you can leave the ancient battlefield at will, I'm afraid things will change outside.

After all, the alien creatures here are as powerful as gods.

"I can't get out, but you can try to take it out." The top of the blood tree suddenly cracked, and a black mist the size of a fist emerged.

It's not dead...

Xiao Yun and others looked at the fist-sized black fog in surprise. They thought that the black fog in the sky was dead, but they didn't expect that the blood tree saved it in the end.

However, the black mist now is only the size of a fist.

Xiao Yun guessed that the blood tree should have deliberately weakened Heiwu's power, otherwise Heiwu might take the opportunity to take action against it.

"Over the years, there have been fewer and fewer martial arts cultivators and magical beasts entering this place, and there is not much it can devour. If it cannot be devoured, it will not be able to regain its strength. In another hundred years, the mysterious voice from deep will come out again, It will definitely die," the blood tree said.
