"How? Brother Li, is this place beautiful? "

Walking into the underground space, the ghost eye was obviously very proud. He opened his arms and said with a smile, as if he was going to reach out to embrace the brilliance of the "sun".

"Tut Tut, it's spectacular."

After smacking his mouth, Lu Li is not stingy in his praise.

Looking around, Lu Li finds that everything here is full of vitality. This space is surrounded by a not so luxuriant tree. In the middle of this space, there is a clear lake. The streams that shuttle through the underground space flow out of the lake and finally circle back, forming many perfect cycles, And this circular river course is obviously for irrigation of some things.

After Lu Li carefully felt the things in the underground space, he was very surprised. There were a lot of spiritual plants in this space, including many precious medicinal materials. Obviously, the ghost eye used this place as a greenhouse for spiritual plants and medicine.

Among them, the most surprising thing for Lu Li is the high hanging "sun". Lu Li can clearly feel that the "sun" is the output place of aura in this space, from which "sun" all the aura in this space diffuses. Here, it is also a very strange environment that transcends the aura vacuum in the sea of empty dust, The aura in the air is extremely abundant, and that aura is light Aura!

Compared with Aurora aura, aura is much more gentle. Ordinary sunlight, moonlight and stars will carry a certain amount of aura, and aura is also the most abundant aura attribute between heaven and earth. However, in such a place, it is not easy to let aura fill the whole space. Think about it, the high hanging "sun", It's the most important part to realize this environment.

"Isn't it amazing? Brother Li, I think it's the first time you've seen something like "Linglong"

It seems that Lu Li has a strong interest in the high hanging "sun", and the ghost eye immediately says with a smile.

"Spirit cage?"

Lu Li slightly raised his eyebrows, which is a very new word.

Through soul perception, Lu Li can roughly find that the structure of the "sun", which is called the spirit cage, is very similar to the artificial air sea. Although it is not as perfect as the artificial air sea, and even the power of space can be stored in it, the so-called spirit cage can store a lot of spirit, and the amount stored is much more abundant than today's artificial air sea, According to Lu Li's estimation, the aura filled with such a spirit cage is enough to fill the artificial air sea more than 30 times!

It's an extremely large number. You know, the artificial air sea can store the sum of the three spirit sea top level strongmen. That is to say, such a spirit cage can store the total amount of the spirit of nearly 100 spirit sea top level strongmen!

That number is already an astronomical number. A strong man of spirit level does not have so much aura in his body, and there are four such spirit cages on this ghost lamp island alone!

This is quite a terrible thing. The ghost lamp Pirate Group is not the number one force in this coastal area. The five emperors' forces must be even more terrible. I'm afraid that any one of these things will cause a huge sensation if they are put in the territory of cloud country!

Lu Li's heart was full of interest in this thing. If he could understand its principle and find the right material, man-made Qi sea could greatly improve the Tao. Even if he could not upgrade it to the so-called infinite aura in theory, it would be terrible to have such a huge amount of aura.

After all, it's not like the floating world pearl. It can form a world of its own. The laws of space and time are perfectly included in it. Lu Li can feel that it's only the level of Qi pin Lingqi, but its strange degree is still beyond Lu Li's understanding of forging together!

"Tell me about this so-called spiritual cage. What is it?"

Lu Li toward the ghost eye Nu chin, hands ring in front of the chest, with interest waiting for the ghost eye explanation.

The ghost eye didn't mean to hide anything. He found a stone and sat down. Then he opened his mouth.

"The spirit cage is really a very magical thing for people who have never seen it before, but it is only useful in the sea of empty dust, and it has little effect on the outside world. I think I can feel it by virtue of your spiritual cultivation of seven elixirs. The purpose of this thing is to store a large amount of aura, and then feed it back. In this aura vacuum environment, open up an area covered by aura. "

"Isn't that a great thing? Why is it useless to put it outside? "

Lu Li shriveled and asked.

"Ha ha, this thing itself has great limitations. The first thing is the coverage. The scope that this thing can cover is the size of the underground space. It's about 100 meters long and 100 meters wide. If it goes beyond this scope, it can't be covered. Moreover, you should also feel that the thinner the aura is, the more it can compete with the outside world, It's about 30 meters after that. "

"What's more, this thing itself is equivalent to a heavy bomb. If this thing is destroyed, the aura will gush out, and the power storm can easily kill the strong one in the spirit sea. Therefore, this thing can only be used in some absolutely safe places."

Ghost eye shrugged to explain a way, and hear ghost eye this words, Lu Li just in the heart understand a few minutes.

It seems that the way he wanted to carry these spiritual cages on the ship, if directly implanted into the human body and other means, still does not exist, which also makes Luli feel relieved.

After experiencing the guy Xie Guyuan, Lu Li is also very defensive about the means of reconstructing the body structure of the spiritual master. After all, most of the people who can be connected with these things are like Zhou Yunhai and others. They are supernatural aliens.

"Speaking of it, this spirit cage should be your equipment for collecting aura value?"

Holding his chin, Lu Li continued to ask after thinking for a moment.

"Yes, the source of this thing's aura is actually its value."

The ghost eye nodded and said, "normally, people on the island should take four different spiritual cages with them. The markets, stores and all spiritual values in the western district are provided for this spiritual cage. This is equivalent to all the savings of the store manager. If there is no way to support it, I can't get such a space to see from the bottom, Cultivate these plants. "

After listening to this, Lu Li completely understood the meaning of the existence of aura value.

In this sea of empty dust, only the area covered by these spiritual cages can really have aura. The value of aura is not only used for consumption, but also the aura fed back to consumers. In this way, it forms a very good cycle, and it is also a very reasonable way. I'm afraid that in other larger forces, the existence of such things as spiritual cages is very important, It's going to take a lot more.

"But as an outsider, why do you introduce these to me so warmly? You can't tell me just because I'm handsome, can you? Come on, what do you want from me? "

After a little surprise in his heart, Lu Li also converged his mind. In the future, he will certainly explore the sea of empty dust, but not now. What's more important now is to find out what the ghost eye wants.

Lu Li would not believe that these pirates would do anything purposelessly.

"Ha ha, brother Li, you are very pleasant. Now that you ask me, I'll be frank."

As he said this, the ghost eye pulled up the sleeve of his arm. Lu Li immediately saw that there was a black line like a centipede on his arm. Obviously, it was a poison!

"I know that you are a seven grade elixir, so I want you to detoxify me."
