Gao Fei had seen a lot of immortals before, and there were sayings such as cave heaven in them, which meant a cultivation treasure land with abundant spiritual energy.

He searched with a search engine and found that Jiuzhou has had ten major caves since ancient times.

In the Wangwu Mountain in Zhongzhou, there is a Wangwu Cave, known as "the sky of small and void existence".

In the west-leaning mountains of Dezhou, there is another Xicheng Cave, known as "the heaven of Taiyuan Zongzhen".

There are also two caves near Fandu, one is the Weiyu Cave of Weiyu Mountain, known as "the sky of great emptiness", and the other is the Chicheng Cave in the Chicheng Mountain, known as the "Heaven of Purple Jade Qingping". These two caves are within 300 kilometers of all the cities, and they can be reached in a day's journey.

The other caves are distributed in many places in Jiuzhou, and the more Gao Fei looks at it, the more strange it becomes, and when he opens the information of the Special Administration Bureau, he can't help but widen his eyes.

In the Special Administration's aura vulnerability data, there are ten S-type vulnerabilities that are very consistent with these ten caves.

If there are only one or two coincidences, it can be said to be a coincidence, and all ten can correspond one by one, then it is definitely not a coincidence.

It can be seen that the cave is the aura loophole, a special space created by the aura accumulation of the S-level aura loophole!

It turns out that there were aura loopholes in ancient times, and the ancients had long used them to cultivate.

Determining that the small aura cave was where the detected aura loophole was, Gao Fei no longer hesitated.

With no one around, Goofy spent 30,000 energy to exchange for a set of black technology diving suits.

Well, the payment over there is successful, and Gao Fei's body here is covered with a thin film, which can not only absorb the oxygen in the water and breathe like a fish, but also have a strong protective effect.

Goofy moved his muscles and plunged headlong into the water.

Gao Fei's swimming level used to be at the bathroom level, that is, he could float in the water, and the dog planing was considered a difficult maneuver for him.

After genetic strengthening, his physical fitness in all aspects has improved a lot, and he can be regarded as half a superman, and his swimming skills have also been greatly improved. I dare not say that I will participate in the Olympic swimming competition, at least the dog planing technology is unbeatable!

With the black technology bonus of the wetsuit, Gao Fei dived like a fish as soon as he entered the water.

In Fandu in early winter, the lake water is cold to the bone, but Gao Fei has a breath of internal qi in his body, swimming between his limbs and hundreds of remains, and his body is naturally warm to resist the cold of the outside world.

The sunlight was hazy through the water, and Goofy swam towards the center of the lake according to the guidance of the aura detector.

Xiaojing Lake is very wide, fortunately, Gao Fei's physical strength is strong and his speed is also fast, and he came to the center of the lake after ten minutes.

4045！

The further you go to the center of the lake, the higher the value of the detector will be, and you will reach the center point. The Reiki detector gave a new high value, which made Gao Fei speechless.

The depths below the lake are still attracting the constant swing of the detector pointer, and there seems to be a stronger concentration of aura there.

Goofy didn't hesitate too much, swung his body, and went downstream.

Xiaojing Lake is not deep, even the deepest part of the center of the lake is only about 20 meters deep.

In the center of the lake, there was a hole in the gravel, and a layer of spiritual light flickered at the mouth of the hole.

4188！

The value of the detector has skyrocketed again.

Gao Fei leaned over in surprise and joy, and found that the aura was like a protective shield, protecting the hole, and the lake water could not be poured in.

But what is this hole?

Could it be the cave?

Goofy tried to approach the hole, and the moment his fingers touched the shield, his entire body was suddenly wrapped in a wonderful force, and he was involuntarily sucked in.

It was dark, then bright, and Goofy found himself in an underground cavern.

It is a natural cave, about thirty or fifty square meters in area, with several stalactites on the top of the head, surrounded by jagged rocks, and a small empty space in the middle.

When I looked up, I saw that the entrance to the cave was blocked by spiritual light, preventing the lake from entering.

"It's amazing!" Goofy was surprised.

This space is like a small world, no wonder it is called a cave, and there is indeed a sense of transcendence and isolation from the world.

And as soon as Goofy entered this place, he faintly felt a breath of qi stirring in his body.

This qi is the internal qi generated in the body after the Xingyi Fist reaches the strength of the body, and it swims freely among the limbs and hundreds of bones on weekdays, like a lively little snake.

Perhaps stimulated by the aura here, the little snake seems to ride the wind, its head is higher and higher, and its body is almost upright, like it has evolved into a king cobra with its tail on the ground and its whole body standing straight, almost soaring.

Goofy's mind moved slightly, and he quickly contacted the Star Destroyer to ask what was going on.

"Drop, the Star Destroyer has detected that you are in an extremely suitable environment for cultivation, do you want to exchange for a higher-level ability (note: redeem here, there is a seven-percent discount)? Recommendation 1: Intermediate Martial Dao; Recommendation 2: Elementary Cultivation; Please choose?"

Before Goofy's eyes, two different evolutionary routes appeared.

One is martial arts.

Intermediate martial arts, concave abdomen and chest sucking, empty chest and tight back, dragon and tiger sitting, hand holding Mount Tai, head like a hanging rock, air through the dantian, this is the succession. Practicing qi is yin for the congenital, and the use of the limbs and six yang is the acquired, and the unity of heaven is for the middle martial arts.

The first is to cultivate the truth.

Refining qi out of the ordinary, get the qi of heaven and earth, absorb the essence of the sun and the moon, people are small days, the sky is big days, heaven and man are one, the human body and the celestial bodies are combined, reunion is like a pearl, and it can be a sword immortal.

To open an intermediate martial art, it would have required 200,000 emotional energy, but in the cave sky, it only needed 140,000.

To open the primary cultivation, it would have required 300,000 emotional energy, and 210,000 in the cave heaven.

There are still a lot of discounts, and Gao Fei can afford it.

He simply asked, "Can I choose both?"

"Yes. The Star Destroyer replied in the affirmative, "As long as you can afford the energy required for the evolutionary route, you can choose as many routes as you want at the same time." ”

"Both are on!" Anyway, he has energy at hand, and he is about to deal with Ma Rulong, Gao Fei is not stingy.

There was a throbbing inside his body, and Gao Fei only felt that there had been a slight change in the entire life level.

Then he let out a comfortable moan, it felt like kissing Ma Xiaoling for the first time, it was so cool!

It was only at this moment that Goofy finally understood what the aura concentration of 4188 meant.

When an intermediate martial artist and a junior cultivator entered a cave with an aura concentration of more than 4,000, it felt like ......

Xing Ye starred in a comedy movie again!

The rich thief has restarted the hunter!

The future king of heaven three changes a day!

The eunuch has a younger brother again!

The single dog soaked in the goddess of dreams!

Anyway, go dream.
