Twelve years have passed since then, and the Great Elder has lived up to expectations and reached the state of ascension.

Because of the Heavenly and Earth Treasure Protector obtained from the Great Sage Realm, the Thunder Tribulation was no longer a harm to the Great Elder, so in the end, when the aura shone on him, he said to Lu Chenyao and the fox: "You must kill the fallen immortals, and then come up, I will wait for you in the immortal realm!"

Lu Chenyao and the others naturally agreed.

After sending the Great Elder away, she said to the fox, "Where did this fallen immortal go? We just waited, and we don't know when he will appear!"

The fox said: "I guess he's in that magical world, it's really difficult to find the portal from another dimension, and it's even possible that he can't find it at all!"

Lu Chenyao: "Such a situation is not impossible, so do we have to continue to wait now?"

Fox: "The matter has come to this, what else can we do if we don't wait, it's better for us to hide it now, so as soon as the fallen immortal appears, we will catch him off guard!"

Lu Chenyao nodded in agreement.

In fact, they still have some things to do in this spiritual realm now, for example, when they first came, when they met that green-faced hideous roar, they must have killed him quickly.

After that, the fox released the detained people, and he didn't know how to settle them, so he finally paid for them and handed them over to the nearby sect forces for placement.

"Aren't you going to go to that bottomless abyss to find out why your aura is depleted every thousand years, let's go there once, solve the problem and come back!" said the fox.

Lu Chenyao naturally readily agreed, and on this day, they came to the entrance of the bottomless abyss in the northernmost part of the Upper Spirit Realm.

Due to the suppression of cultivation, the demon beasts here trembled at them, and Lu Chenyao and the others didn't hurt these demon beasts, so they jumped down directly.

In the bottomless abyss, it is a paradise for demon beasts, there are many kinds of demon beasts in it, and when they see two people cultivating in their own place, their first reaction is to attack them in groups.

But Lu Chenyao's strength is outstanding now, and even the foxes are much stronger than them, and they are defeated and scattered in only a few clicks.

The fox took Lu Chenyao and directly found a demon beast with the highest cultivation here, which was known as the king of beasts.

When the King of Beasts saw Lu Chenyao and the fox swaggering into his territory, his eyes were already sharp.

Because the fox is a fairy body, it can't see through it, and only thinks it's two humans.

When the fox defied its warnings and told him that he wanted to solve the spiritual energy depletion event that they had to face every thousand years, the King of Beasts was pleasantly surprised to hear what they meant.

He even said that as long as Lu Chenyao and the others found out the reason for the depletion of their spiritual energy, they were willing not to invade human cultivation again.

Although Lu Chenyao and the others are no longer uncommon in the promise of the king of beasts, they still agreed.

Next, the fox specifically asked the king of beasts about the reason for the depletion of spiritual energy.

It turned out that in their bottomless abyss, there was a valley, this valley was very strange, it usually only had a slight suction, which was really not surprising in the cultivation realm.

But every time it reaches the tipping point of a thousand years, it will absorb the aura of the entire world like a bottomless pit, causing the aura of this world to dry up.

The King of Beasts also tried his best, but it seemed that this was not a place where ordinary people could enter, so they were helpless.

So the fox asked, "How can you say that it is not a place where ordinary people can enter?"

The King of Beasts said: "That's because this place is like a bottomless pit, everything that falls to it will disappear without a trace, and no matter how high your cultivation is, you can't turn back."

The fox frowned when he heard this, he turned his head and exchanged a look with Lu Chenyao, and for a while everyone felt that it was extremely tricky.

So the fox said, "Then please ask the king of beasts to take us to see it, so that we can know what the situation is!"

The King of Beasts didn't have too much rejection of these two humans who didn't want to fight their demon beasts at all.

He then instructed a cronie and took Lu Chenyao and the fox to the valley.

Standing at the entrance of the valley, Lu Chenyao looked back at the fox, and the fox nodded at her.

Their actions caught the attention of the monster that led the way, and the monster asked them, "Do you know something?"

The fox shook his head and said, "I don't know, I have to look at it to find out!"

Lu Chenyao hurriedly nodded in agreement.

But they actually knew that the situation here was somewhat similar to the situation of the black hole they had captured in the void world outside the Great Sage.

The demon beast didn't bother, it didn't even dare to believe that Lu Chenyao and the two humans were so capable that they knew what the situation was like here as soon as they came, so it wasn't disappointed.

The fox said to him, "Go back, and we'll look around here." ”

But the demon beast said: "Our king said, let me serve you, so I can't leave!"

The fox understood that the King of Beasts had always been wary of him and Lu Chenyao, and it was normal to find someone to spy on them.

But what he does now, there is no need to hide it, after all, cultivation is hard power, and no one else can stop him from doing anything.

So they no longer paid attention to this demon beast, and the fox began to carefully study this thing with Lu Chenyao, which was like a black hole.

Of course, at first they had already felt it outside the valley, and they found that the black hole was actually not very large, that is, a hole with a diameter of more than four zhang.

At this time, the demon beast was already far away from them, and he looked at them from a distance and said, "Hey, you two had better stay away from that black hole, it can suck you in, then you can't come back!"

The fox nodded, and of course they could feel the strong suction.

Fortunately, their cultivation is profound, but they are not afraid.

Lu Chenyao began to transmit the voice to the fox and discuss the problem of this black hole: "Fox, do you see that this black hole is the same as the small black holes in the void?"

The fox said: "Theoretically, this performance is the same. Or that the little black holes that we capture in the void have just formed, and this black hole is a shaped. ”

After thinking for a while, he said: "The human beings in my previous world studied a little bit about black holes, saying that black holes will suck in all the matter around them, and if the matter enters it, it will slowly become a state of time regression...... What do you think is going on?"

The fox looked at the mountains and rivers around him that had not been sucked away, so he said: "I personally think that this world should be fundamentally different from your world, and we still don't want to study these overly advanced knowledge of the universe, because unless it is a Mixed Yuan Emperor who can completely penetrate the heavens and the earth, otherwise a person like us who cultivates will not be able to fully understand all kinds of celestial situations, I think the first problem we need to solve now is how to bind this black hole so that it will no longer harm the creatures of this world!" ”

Lu Chenyao: "That's right, this is the reason why each world has its own laws and all things have their own formation, and we really can't investigate the root cause of all kinds of things." But fox, can't your space-time ban bind such a big black hole?"

The fox shook his head: "I'm afraid it's a little difficult!"

Lu Chenyao naturally couldn't think of any good ideas, and her mind was spent on how to dance and make swords.

Therefore, the work of thinking about the problem is all solved by the fox.

In the days that followed, they watched the black hole day and night, and finally the fox said, "I found a problem, this black hole is fundamentally different from those black holes. Others, such as the black hole we encounter in the void, are simply with a certain suction.

And this black hole is able to release a certain amount of aura.

I don't think it's a real black hole, there should be something peculiar in it, it can absorb aura, and it is physical. ”

Lu Chenyao asked, "You mean to say that there is an entity in this?"

The fox nodded: "If it's a void, I don't think we can do anything about it, after all, there is no boundary." But if there's an entity in there, I think we can use an extradimensional portal to get in and find out why!"
