"Spirit Cave, Fu Lao, what Spirit Cave? Is it that big earth pit?" Xia Leilin asked suspiciously, he had never seen Fu Lao lose his temper like this, and he couldn't help but be curious about the Spirit Cave in Fu Lao's mouth.

"Yes, this big dirt pit is the spirit cave!" After being surprised for a while, Fu Lao's mood had calmed down, and he said affirmatively:

"The spiritual cave is still the place where the spiritual energy of heaven and earth gathers, and the spiritual energy of heaven and earth within a domain is gathered in a cave. ”

The big pit in front of him was just a three-meter-diameter, two-meter-deep dirt pit, nothing unusual, the only thing that made Xia Leilin feel interesting was that above this dirt pit, there was a whirlwind that kept spinning endlessly, straight into the sky.

"Cave Heaven Blessed Land? There is no Cave Heaven Blessed Land here" Xia Leilin looked at everything around him, the top of this mountain was bare, there was not even a single grass, how could there be a cave heaven blessed land.

"Spirit Cave, where the spiritual energy of heaven and earth gathers?Fu Lao, could it be that the situation of this mountain is related to this Spirit Cave?" Xia Leilin asked thoughtfully.

"You're right, this mountain lacks spiritual energy, the vegetation is not abundant, and there is no grass on the top of the mountain, precisely because there is a spiritual cave on this mountain," Fu Lao said:

"In fact, this spiritual acupoint is not mature, it is still in the nascent state, and it is still gathering the spiritual energy of heaven and earth, therefore, all the spiritual energy around this mountain peak is empty by the spiritual acupoint, and you see that the spiritual energy vortex above the spiritual cave is composed of the spiritual energy of heaven and earth. ”

"It's really a huge aura whirlpool! if you absorb all the aura in this aura whirlpool, I don't know if you can cultivate to the middle level of qi cultivation?" Xia Leilin couldn't help but sigh as he looked at the huge cyclone in the spirit cave.

"Not to mention the middle level of qi refining, even if you achieve the top-level Great Perfection realm, there is no problem," Fu Lao said: "However, this is impossible to achieve. ”

"The aura in the aura vortex is extremely violent, if there is no strong body that is strong enough to withstand the strangulation of the aura vortex, no one can absorb and refine it, if it is forcibly absorbed, it will only be torn to pieces by the aura vortex, or the violent heaven and earth aura will explode and die. ”

"And the result of a high-level Qi Refining Martial Artist entering the cyclone is only to be torn to pieces by the cyclone!"

"If that's the case, then this spirit cave doesn't have any effect on us at all?" asked Charelin.

"That's good!" Fu Lao said affirmatively: "Unless this spiritual acupoint can complete the transformation and change from internal to external feeding, this place will become a real cave heaven blessed land, and become a holy place for cultivation, before it can be used for you to practice." ”

"However, I don't know how many years it will take, maybe it won't be completed until tens of thousands of years later!"

"So, Lei Lin, you better go into that hall and see what you can get, after all, this hall is where the treasure really is!"

"That's right, it seems that I don't have a chance to use this spirit cave!" Xia Leilin glanced at the spirit cave and said secretly, but turned around and walked to the closed door of the main hall.

Although this hall is a big hall, it is not very big, but it is five meters long and wide, three meters high, and the whole body is built with lapis lazuli, and the lapis lazuli is carved with cloud patterns, which is simple and mysterious.

"Squeak... When!····"

Xia Leilin gently pushed, and the huge hall door that seemed to be very tightly closed opened automatically, and a huge hall with tens of thousands of square meters and tens of meters high was displayed in front of Xia Leilin.

For a moment, Xia Leilin was stunned, and the thousand-year-old ghost Fu Lao was stunned.

"This—this is definitely not an ordinary treasure!" Fu Lao muttered to himself.

"I know!" said Xia Leilin in a distraction, the various abnormal things he encountered today had already shocked him a little numb.

"Secret Law Space! This is the Secret Law Space!" Fu Lao shouted in Xia Leilin's mind, "I have seen many treasures in my life, and I have explored countless ruins, but I have never seen such an exquisite secret law space in any treasure ruins!"

"Secret Space?" another unfamiliar word appeared in Xia Leilin's mind.

"That's right, the secret space, a space that only the true powerhouses of the ancients can create, can open up an independent large space in a tiny space, just like this hall," Fu Lao explained.

"Isn't this similar to space equipment?" said Charelin disapprehantly, "Is it so mysterious?"

"Different!" Fu Lao Zhengse said: "The space in the space equipment comes from its constituent materials, just like the Sumeru spar on the soul bracelet, the space inside it is fixed. ”

"And the size, shape, etc., of the secret law space, are completely determined by the maker himself, and are created by the creator with the space secret magic power, which is the real great magic power!"

"This kind of hall with a secret space has been built by very few people thousands of years ago, this should be built by an ancient powerhouse, and it is specially used for inheritance purposes. ”

However, Fu Lao's answer didn't play a big role, without the corresponding knowledge, Xia Leilin couldn't understand the meaning, he only knew the way, according to Fu Lao, this hall seemed to be built by a very powerful person.

Fu Lao then also understood this, and sighed: "Alas, Lei Lin, you may not understand what you say now, you better go directly into the main hall, I believe that the things inside can make you understand the meaning of what I said!"

"Well, it's good!" Although he didn't understand what Fu Lao said, Xia Leilin knew that this time he seemed to have taken great luck and would get something very good.

"Legacy?····" Xia Lerin thought as he walked into the vast hall.

When Xia Leilin walked into the main hall, Xia Fan, who was watching all this from a distance on another mountain, let out a sigh of relief, the Fu Lao behind Xia Leilin was too powerful for Xia Fan, this was from the strength of the soul.

When that Fu Lao appeared from behind Xia Leilin, Xia Fan was really startled and almost screamed, but the aura emanating from Fu Lao's body scared Xia Fan's voice back.

With Xia Fan's perception ability that was dozens of times beyond ordinary people, he could clearly feel the powerful oppressive force, permeating a radius of thousands of kilometers, revealing a spiritual coercion, and even permeating around the mountain peak where Xia Fan was.

Xia Fan knew that it was this coercion that made the fierce beasts dare not approach the surroundings of Xia Leilin, and Xia Leilin dared to enter the Yandang Mountain Range, which was dominated by fierce beasts.

Before, this Fu Lao was obviously hidden, and he had gathered his strength and aura, and even Xia Fan, who had a keen perception, was not aware of his existence.

But now, in the midst of these barren mountains and mountains, it is obvious that this Fu Lao did not hide his meaning anymore, and showed his true body, exuding his true strength.

In the face of this powerful force, Xia Fan could only use all his strength at this time, constricting the qi and blood aura of his body, and did not dare to move in the slightest, he now only hoped that the breath gathering technique he had learned from mortal martial arts could play a role.

It wasn't until Xia Leilin entered the main hall that the powerful power of oppressing the soul blocked the main hall that Xia Fan let out a sigh.

"It's really lucky, the protagonist looks like a lucky protagonist! and he also has the old ghost grandfather as a plug-in," Xia Fan looked at the hall on the mountain peak in the distance and sighed:

"Fortunately, my breath collection technique is an exercise specially created by ordinary martial artists to avoid low-level fierce beasts, and it can restrain the strength and breath of a body, otherwise it would be really difficult to surpass them. ”

Just when Xia Fan was full of emotion, Xia Leilin, who had already entered the main hall, was in big trouble, yes, big trouble.
