When I was a child, Su Xie read the book "Ancient Chronicles" that had records about similar blood beads, like this blood-red bead, most of them were fierce beasts or demon beasts' inner dan, but one difference was that there were no lines on the inner dan of fierce beasts, but demon beasts did.

The inner dan with lines proves that this is a creature whose blood is much higher than that of the fierce beast, that is, the demon beast, and the inner dan of the demon beast and the fierce beast is very different from the inner dan of the human being, the inner dan of the human is made of essence, and the inner dan of the demon beast and the fierce beast is made of the essence blood, which is why this bead is blood red.

However, not all demon beasts' inner pills can cultivate the lines, ordinary demon beasts can't do it, even if they cultivate for thousands of years, it is impossible to form patterns, and the demon beasts that can form lines are very few.

But there is not much difference between the two in essence, it is just a sign used by God to distinguish between humans and beasts, people refine qi, beasts refine blood, and cultivation can still be continuously improved through hard work.

As for the lines on the inner dan, there is also a certain amount of exquisiteness, the demon beast with the cloud pattern blood beads has its own unique inheritance bloodline, such a demon beast has its own family, just like the royal bloodline of the Tianluo Temple, their ancestors have formed their own huge family, this kind of demon beast is very powerful, even the human forces dare not easily provoke.

In addition, there are also thunder patterns, cloud thunder patterns, and the demon beasts that form the thunder pattern inner pill have at least two thousand years of cultivation, and they are the overlords of one side, and they can be called the princes of the demon beasts. And the Cloud Thunder Pattern is completely different from the previous two, a demon beast can cultivate the Cloud Thunder Pattern at the same time, and it is an existence that is about to enter the transformation realm.

If the demon beast with the thunder pattern is the prince, then the demon beast with the cloud and thunder pattern is the emperor, the so-called transformation realm, which means that it is about to be feathered into an immortal, but the demon beast cultivates to a certain height, not to become an immortal, the immortal is only the superficial meaning, and the real incarnation is a dragon.

A demon beast with a cloud and thunder pattern can evolve into a pure-blooded dragon.

Su Xie was amazed that he could have this good luck, and he actually let him pick up the demon beast Neidan with cloud patterns, this cloud pattern blood bead was even more powerful than the Heaven and Earth Yuan Power contained in the Phoenix Fruit, if he absorbed it and promoted to the fifth order of the Heavenly Master, it would not be a problem at all.

"The cloud pattern blood bead, the head of the sect once almost turned over the entire Shu Mountain for this bead, but he still didn't find it, I never thought it was hidden in this place, it's really strange?" sighed the eldest disciple.

Su Xie was puzzled, "Who would hide such an important thing here?"

The eldest disciple paused, and then said: "This has to start from a long time ago, it is said that when the Kendo League first moved to Shushan, it was found that there was a giant dragon hiding under the ground thousands of meters deep, the dragon did not like the arrival of outsiders, they disturbed it, the dragon was very angry, killed nearly half of the children of the Kendo League, at that time there were only two thousand people in the Kendo League, and a thousand people were all killed by the dragon. The alliance leader and the remaining more than a thousand people fought desperately to reluctantly seal it in the underground demon cave, where there was originally an ancient sealing formation, I don't know who left it, they re-applied mana on that formation to trap the dragon. At that time, the dragon was pierced through the dantian by a sword, and the inner dan fell out, but unfortunately, people did not find it, until many years in the past, the head of Shushan had heard of such a thing, so he personally sent someone to the underground demon cave to find, but still did not find it, no one had ever seen what the inner dan looked like, only the person who pierced the dragon through the dantian with that sword had seen it with his own eyes, he said that the bead had a cloud pattern, which was easy to identify, but even now, no one has found the blood bead with a cloud pattern. ”

But he didn't expect that such a treasure that the head of Shushan had to find with great effort was easily obtained by Su Xie, or it was discovered by accident, so Su Xie was born with this bead.

"Dragon's Inner Dan, isn't that the case?" Su Xie glanced at the blood bead in his hand again, isn't this clearly the Inner Dan of the demon beast?

"That's right, we just call that demon beast like that, it's all because he looks like a dragon, it's actually a demon beast with a high bloodline, but for some reason, he was imprisoned in an underground demon cave. The eldest disciple said.

"What kind of place is that?" Su Xie thought to himself, as if when he first arrived in Shu Mountain, the shadow guard felt a dangerous aura, it said that it was the breath of a demon beast, and it was hidden underground.

Judging from this, the story told by the eldest disciple is true, there is indeed a demon beast trapped under the ground several thousand meters deep.

"It's a very dangerous place, it's usually a place for disciples to conduct brutal training, there is not only a demon beast, but there are many fierce beasts, but there are two separate places in the underground demon cave, one side is where the fierce beasts live, and the other side is the space where we move, as long as we don't trespass into the territory of the fierce beasts, there will be no problem, in fact, to be precise, those fierce beasts are locked inside, and they can't get out. As soon as the eldest disciple thought of the underground demon cave, his eyes revealed fear.

But no matter how dangerous it was, Su Xie planned to take a look, he wanted to see with his own eyes what kind of legendary creature that demon beast was.

"What I can't figure out the most now is, who hid Neidan here? It seems that in the Kendo Alliance back then, there was an inner ghost, that person betrayed the Kendo Alliance, and secretly hid Neidan by himself. The eldest disciple said to himself again.

This is also Su Xie's most puzzled question, but if it is a betrayal, it is not counted, this person did not swallow Neidan alone, but has been hiding in this place, but after so many years, that person has not come back to get it.

Is it already gone, or is it already dead?

"How long has this temple been built?" Su Xie looked up at the roof.

The eldest disciple thought for a while and said, "It's been a long time, since the establishment of the Shushan faction, and the construction of this temple must also be a kind of awe of the sword alliance leader for the dragon, right? Maybe it was because the dragon slaughtered too many people, and there was already a lingering shadow in the heart of the alliance leader." ”

It's not too early, after talking about this, Su Xie felt that he should continue to move, he temporarily put the cloud pattern blood beads into the Qiankun bag, and suddenly had an idea, such an important thing, someone has been hiding it for decades, there must be a reason.

Su Xie wanted to go to the underground demon cave and ask the demon beast in person, anyway, without Neidan, he wouldn't be able to do any evil, and besides, he was still sealed and couldn't run out at all.

"Hey, let me ask you, where is the underground demon cave?" Su Xie asked, he helped the eldest disciple up and put one of the eldest disciple's hands on his shoulder.

"You want to go to the Devil's Cave? No, it's dangerous. The eldest disciple looked at him in astonishment.

Su Xie smiled faintly and said, "Just take me there later, I feel that I need to go in once." ”

"You're really weird, you have to go to that kind of place, you don't want to meet that demon beast, right?" the eldest disciple looked at him with strange eyes.

"You guessed it. ”

"My God, if he knew that Nedan was on you, he wouldn't be angry, but I still promised you, who let you save my life. The eldest disciple shrugged helplessly.

Su Xie carefully helped him out of the temple, jumped up, and the two of them flew in the direction of the underground demon cave.

Now that the Liuli Palace is full of people, he doesn't want to fall into a death battle with so many people, presumably Li Wangjing has already killed the red eye just now, who knows what crazy moves he will make later.

I don't know where Zuo Yifeng is now, I hope he is safe, Su Xie thought in his heart.
