Fantasy: The opening reward is one billion years of cultivation

And the other is that this white crystal is something from the devil world.

As soon as this idea came to Ye Xiu's mind, he immediately rejected it.

If this white crystal stone is something from the Demon Realm, then the Demon Realm should have been wiped out long ago. How can there be any demon clans living in the Demon Realm?
What's more, the energy fluctuation contained in this white crystal is very powerful, and the drop of water in this white crystal also contains very powerful energy.

Therefore, according to Ye Xiu's speculation, this white crystal should be the source of the blood of the demon clan.

The Demon Realm is a gigantic monster, its strength is far stronger than that of the Heavenly Demon Realm. If there were people from the Demon Realm, they would have been wiped out long ago.

Moreover, for so long in the Heavenly Demon Realm, those forces in the Heavenly Demon Realm have never heard of the Demon Realm, so this Demon Realm does not exist at all.

Ye Xiu guessed that there might be a remnant of the Demon Realm in this Heavenly Demon Realm. Their strength is very strong, and they may even be a demon clan at the level of a Demon Lord. demon world.

"It seems that the remnants of the demon world are quite cunning!"
Ye Xiu shook his head and sighed.

The status of the remnants of the Demon Realm is very low in the Demon Realm, not even the Demon Emperor, but they can avoid the pursuit of the Demon Realm, and they can hide in the Demon Realm, which is enough to prove that their strength is very powerful. Therefore, they Not daring to act rashly, only able to hide.

However, Ye Xiu felt that this remnant of the demon world was too stupid to do such a thing.

"It seems that we still have to help them!"
Ye Xiu said to himself, and then he took out a few formation flags from the Qiankun bag and placed them in the cave, and then he went into the cave.

It was very cold and damp in the cave, but for a strong man like Ye Xiu, there was no problem at all.

Soon, he smoothly entered the depths of the cave.

Inside the cave, it was very dark, and it was impossible to see anything clearly.

However, for Ye Xiu, as long as he is not blind, he can see the surrounding environment clearly through the string of beads on his wrist, so Ye Xiu is very safe going forward.

However, what surprised him was that the depths of the cave were so dark that he couldn't even see his fingers.

But in the center of the cave, there is a shimmering white crystal, and within that white crystal, there seems to be a cloud of black mist. In this black mist, there seems to be a huge black bat.

"Huh? That thing looks familiar"
After Ye Xiu saw the shimmering white crystal, he suddenly thought of something, his eyes lit up immediately, and an excited expression appeared on his face.

The white crystal stone that shone with a faint light was exactly the white crystal stone that Ye Xiu got back then!
Before Ye Xiu left, Ye Xiu took the white crystal stone away. Moreover, the white crystal stone can exert a powerful effect in Ye Xiu's hands, so Ye Xiu kept it by his side at the beginning. But unexpectedly, I met such a baby again today.

Ye Xiu's face was full of joy, and he hurriedly walked towards the cloud of black mist.

The black mist was huge. In Ye Xiu's opinion, it must be at least as heavy as a thousand catties.

"This white crystal, who left it in the cave?"
Ye Xiu looked at the black mist and muttered to himself, his eyes were full of doubts.

If it was outside, many people would definitely choose to bypass the black mist in such a situation.Because, if there was really a fierce beast inside the black mist, and it was a demon beast at the level of a demon king, then Ye Xiu might die without a place to bury him.

But now, Ye Xiu's cultivation has reached the peak of the Eighth Level of Martial Saints. With such a tyrannical cultivation, he is not afraid of powerful people at the Demon Lord level at all.

So he wanted to try to enter the black mist, to see what the black mist was, and to see if there were any ominous beasts lurking in the black mist.

"call out!"
At this moment, the black mist suddenly moved.

The black mist suddenly rose into the sky, and then flew towards Ye Xiu's body.

"Fuck, this thing actually wants to bite me?"
Seeing the black mist suddenly pounce on him, Ye Xiu's eyes suddenly shot out. The speed of the black mist was so fast that Ye Xiu didn't even have time to dodge it.

"Boom~"
However, at the moment, Ye Xiu swung his fist vigorously, and punched the black mist fiercely. The strength of his fist burst out, and instantly bombarded the black mist, instantly killing the black mist. Completely destroyed!
"Haha, it's so cool!"
At that moment, Ye Xiu couldn't help shouting, the black mist couldn't even block his punch, it was so powerful.

However, at this moment, a scream sounded suddenly!

As the screaming sound came out, Ye Xiu saw that from the black mist, there were black sharp blades, like long swords, slashing towards Ye Xiu crazily, extremely fast, within the blink of an eye. In a short time, he was already in front of Ye Xiu.

"The attack of this thing is too fast, right?"
Seeing this scene, Ye Xiu's eyes widened, and his heart almost jumped into his throat.This thing is simply too dangerous.

"Whoosh whoosh whoosh."
Those sharp black blades struck Ye Xiu in an instant, and then Ye Xiu felt a sharp pain, which hit him instantly.

"Pfft~"
On Ye Xiu's right arm, a piece of flesh was cut off instantly.

Fortunately, Ye Xiu's reaction speed was very fast, so although his right arm was chopped off, no blood flowed out.

Ye Xiu quickly held his right arm with his left hand, and then circulated the Gang Yuan in his body again to start healing.

In any case, he must recover as soon as possible at this time, because he still has a lot of things to deal with.

Moreover, he also wanted to find the bones of the Demon Lord, so he absolutely did not allow any injuries. After all, he had promised Lin Yanan that he would find her father and make Lin Yanan's father reborn.

On Ye Xiu's right arm, blood gushed out continuously, but there was no way to stop it. The blood was all evaporated by Ye Xiu's stellar energy, forming a cloud of blood mist, which was then absorbed into the body by Ye Xiu. Make Ye Xiu's body stronger.

"call."
At this moment, Ye Xiu exhaled suddenly, because his injuries had finally fully recovered.

At this time, Ye Xiu also had a smile on his face, because he felt that in this cave, the stellar energy in his body had reached a saturated state.
