The night is already deep.

Whether it is the villagers of Fangjia Village or Luojia Village, they have basically fallen asleep, although the city walls around the station have been established, but in essence, the Fang family's station is no different from ordinary villages, there is still no aura at all, and there is no property worth coveting, so naturally there is no need for anyone to guard anything.

In the deepest part of Fangjia Village, near the Yanbai Mountain Range, an inconspicuous house stands there, from the outside, it is no different from the other newly built houses, they are all boxy rooms, but if you look carefully, you will find that this house is completely black, it is built with a very precious material to isolate the aura, black stone.

There is nothing special about this material, but there is a point, it can isolate the aura, and many monks have found very high-grade medicinal materials in the mountains and forests, but when they have not yet been able to mature the medicinal materials, they often use black stone to cover the medicinal materials, and then hide them so as not to be detected.

The house built with such materials was built by Fang Rui himself, and now, Fang Rui was sitting in this empty room with nothing in mind, closing his eyes and contemplating.

What he was thinking about was how to channel the aura from the Void Cave Heaven into this room.

Although the Clear Void Cave Heaven was in Fang Rui's body, Fang Rui's understanding of the Clear Void Cave Heaven was no more than Fang Chang's, he was able to open the Clear Void Cave Heaven, but he couldn't let the aura inside leak out, and even every time the Clear Void Cave Heaven replenished the Heaven and Earth Yuan Qi in his body, it was not he who took the initiative to absorb it, but the Clear Void Cave Heaven automatically replenished it for him......

When the people of Fangjia Village entered the Clear Void Cave Heaven, he could directly let the entrance of the Clear Void Cave Heaven be displayed in front of them, but the aura in the Clear Void Cave Heaven would not leak out at all.

Although it seems to be unhindered, they are two worlds.

Fang Rui himself had also tried to enter the Clear Void Cave Heaven, but the interesting thing was that everyone else could enter, but his own body could not enter, only his divine sense could enter, he could use his divine sense to enter with the storage bag, but he himself could not enter......

Qingxu Cave Heaven is also a very special one among the ten major cave heavens, except for the most ethereal Jizhen Cave Heaven has never been found, the other cave heavens have been occupied by a certain atmospheric transporter in the history of the Flying Immortal Continent, and then with the help of the endless aura in the cave sky, the chicken dog ascends to heaven, and the entire family or the entire sect enters the fairy world and establishes a great reputation.

As for the Qingxu Cave Heaven, it has only been owned by a few people, and the previous owner is the one who is known as the Almighty Immortal Monarch, and the one who left Fang Rui with a legacy.

According to his current understanding, Fang Rui probably knew that the reason why the Qingxu Cave Heaven was mysterious should be that it was in another world that was different from the Flying Immortal Continent, and although other people could enter and leave freely, it was still not the same world as the Flying Immortal Continent.

And as the owner of the Clear Void Cave Heaven, Fang Rui couldn't enter the Clear Void Cave Heaven, after all, the Clear Void Cave Heaven was in his body, and it was impossible for him to enter the Clear Void Cave Heaven with the Clear Void Cave Heaven - this was a bit tongue-twisting, but Fang Rui knew that he could carry the Clear Void Cave Heaven with him and enjoy the benefits that the Clear Void Cave Heaven brought to him to make up for his true qi at any time, so he couldn't use the Clear Void Cave Heaven to cultivate.

Now in front of Fang Rui, it was the entrance to the Clear Void Cave Heaven.

The room was pitch black, and the Clear Void Cave in front of Fang Rui was extremely bright, Fang Rui could even see the aura surging inside through the entrance, but he was far from being able to draw out the aura inside.

The aura in the Clear Void Cave can indeed be used by him, but after the aura enters the monk's body, it is released as mana, just like the food that has been absorbed by the human body, can it still become food?

Therefore, if you want to draw out the aura in the Clear Void Cave Heaven, you have to find a way to pass through the barrier at the entrance of the Clear Void Cave Heaven and completely draw out the aura inside!

Fang Rui had been sitting for two full hours, and he had been studying the entrance of the Clear Void Cave Heaven with his divine sense, wanting to know what this barrier was.

What Fang Rui didn't know was how much benefit this kind of research would bring to his cultivation.

He had tried to touch the barrier with his hand, but when his hand reached the barrier, it came out of the void and the void.

So he began to concentrate and use all his energy to observe the barrier, trying to find the key to this barrier.

Although the initial investigation was fruitless, Fang Rui was not discouraged, what he wanted to break was the barrier left by the strongest immortal monarch in the history of the immortal realm, with his cultivation of only five grades, of course, it was extremely difficult, but Fang Rui had to crack it, otherwise, the Fang family's residence did not have too abundant aura, and how could the children of the family be cultivated in a better environment.

He sacrificed the Unity Seal, and then continuously input the Yuan Qi in his body into the Unity Seal, how much Yuan Qi in his body consumed, how much Yuan Qi would be replenished for him in the Clear Void Cave in the Sky, Fang Rui just wanted to use guò to find the law of Yuan Qi delivery and find the gap in that barrier.

Fang Rui firmly believed that since the vitality could be transported into his body, then it would definitely be able to be transported into the space of the Flying Immortal Continent!

Since the vitality can enter one's own body, then the aura in the Qingxu Cave Heaven must be able to overflow, but his own strength is poor, and he can't detect what the barrier at the entrance looks like.

Almighty Immortal Monarch Tianzong Genius, listening to Shang Yang, at his peak, he also had a status in the immortal world, such a peerless talent, of course, he can't compare with it now, but now he doesn't need to understand what the principle of the aura barrier is, just to know where the aura comes from, you can explore it there, and get out the aura in the Qingxu Cave.

Just like a well-structured machine, he doesn't need to know how the machine is made, he just needs to know how to use the machine to achieve his goals, and all he wants to explore now is a manual.

The vitality in Fang Rui's body continued to pour into the Unified Seal, and when the vitality in his body was consumed, a trace of vitality also began to replenish it, and Fang Rui's entire mind was focused on exploring the source of the vitality, and soon, another four hours passed.

Six hours passed, and the sky outside had already dawned, and the people of the Fang family had performed their duties and began to build better infrastructure, but no one came to disturb Fang Rui, because Fang Rui had already said that he was going to retreat, and no one should disturb him before he came out.

Qingxu Cave Heaven, the inheritance of the Almighty Immortal Monarch, now Fang Rui can not use much of this inheritance, he didn't have much ability to use it before, now, it's time to use it.

Fang Rui's divine consciousness was all placed at the entrance of the Clear Void Cave Heaven, feeling the slightest trace of undetectable flow of vitality.

It wasn't until the next day that Fang Rui opened his eyes, and his eyes were full of light.

He finally found the spot, the faint but incomparably large passage!

It is at this point that the aura comes out, and when it breaks through this point, the vitality in one's body will be filled with a part.

Fang Rui's divine sense was deeply invested in this point.

When Fang Rui's divine consciousness enters the Qingxu Cave Heaven, it can see the changes of the entire Qingxu Cave Heaven in full view, and it can also conceal the form and enter the most subtle place in the Clear Void Cave Heaven.

Now, Fang Rui's divine consciousness had deeply entered that incomparably small, but incomparably vast point.

At the same time, the vitality in Fang Rui's body was still continuously input into the Unified Seal, Fang Rui did not want to waste these vital energy, such a vital energy input was also constantly refining the Unified Seal itself, now he was a five-grade cultivator, and the Unified Seal was only a third-grade magic weapon, and it was the time to temper it well.

When Fang Rui's divine consciousness was invested at that point, the barrier that seemed to be as thin as a cicada's wings was invested, but when his divine consciousness was invested, he realized how vast the space was!

Fang Rui's divine consciousness flew in this passage, and on both sides of the passage, there were all dense magic arrays, and in just a palm-sized place, there were 100,000 and 8,000 small formations, forming an incomparably fine and incomparably huge array!

And in the entire passage, such a large array, there are more than tens of millions!

Fang Rui began to immerse himself in such a magic circle, the operation of each magic circle could give him a deeper understanding of cultivation, a deeper understanding of the use of spells, he could see that countless spiritual qi entered this channel, and then gradually changed into a vitality suitable for the use of the monk's body in the operation of the magic circle, and then continued to move forward, where he went, it was naturally Fang Rui's body.

This is how the entire magic circle operates, the aura in the Clear Void Cave Heaven has become the vitality that the monk can use immediately in the operation of countless magic arrays, and then according to the amount of vitality consumed in Fang Rui's body, fill it in, and fill it as much as it consumes, never stopping.

Fang Rui's Divine Sense shook his head and continued to fly forward.

This is the place where the energy changes, not the place where the aura enters.

I don't know how long I flew forward, I don't know how many complicated and subtle magic circles I have passed, in front of Fang Rui, a transparent barrier began to appear—this barrier is the Clear Void Cave Heaven.

Fang Rui's divine sense stopped and began to ponder deeply.

Things are much more troublesome than he thought, this channel, the aura that enters will become vitality, which is already the power of the monk himself, and the biggest role of the aura is to allow the monk to gradually transform into the vitality in the body when absorbing, and at the same time constantly enhance the strength of his body and soul, and gradually achieve his goal.

Fang Rui could instill his own vitality into a certain monk, but this kind of vitality was not owned by that monk, he could use this vitality to send out some kind of spell, but after sending it out, the vitality would naturally disappear.

Only the vitality that you have cultivated yourself can master and use.

Since this passage is not feasible, then it is necessary to make another passage, a passage for the aura to leave directly.

This passage is a passage that the Almighty Immortal Monarch doesn't know how much effort it took to hook it up, with his current ability, it is naturally impossible to create such a passage, but his current purpose is not to make the aura of the Clear Void Cave Heaven become the vitality for his own use, but just to let the aura escape......

To put it bluntly, he just needs to punch a hole.

However, this barrier seems to be as thin as a cicada's wings, but in fact it is extremely thick, and it is extremely difficult to make a hole......
