continued to crawl forward for a long time, the air gradually became humid and cold, and there was even a very slight strange sound, Qi An put his ear close to the stone on the ground, listened attentively, and heard a crack sound of "click", this small section of the acupoint where Qi An was instantly collapsed and sinked, and before he had time to react, his whole body fell straight down with a pile of rubble, which scared him out of the sky.

In mid-air, Qi An glanced down, through the unknown blue light, immediately saw that below was a huge natural grotto, narrow at the top and wide at the bottom, with a height of 100 zhang, like an inverted bowl, the bottom was pitch black, faintly reflecting the surrounding scene, it seemed to be a huge underground lake.

"Plop—"

Qi An fell into the lake, the water temperature was cold to the bone, and his limbs became stiff in an instant, but fortunately, he was not an ordinary person, but a martial artist with a successful cultivation, and his body was strong in qi and blood, so he quickly adjusted his posture and swam upward.

With a "bang", Qi An poked his head out of the water, carefully looked at the surrounding environment, and saw a small island near the center of the lake in the distance, on which something seemed to flicker strangely, but because it was too far away to see clearly, curious, he swam in that direction.

It is said to be an island, but it is not really counted, but it is a few zhang square, slightly protruding from the water, like a big stone standing on the water. When he got closer, he realized that it was not a stone at all, but a large ice floe, formed by the freezing of the lake, like an Iceland, and the strange and flickering thing happened to be in the center of Iceland.

"It's cold!"

As he climbed up to Iceland wet, he felt a biting chill coming to his face, which was far lower than the temperature under the lake, making him shiver involuntarily.

Zian looked curiously at the center of Iceland, and saw a strange object the size of a fist, dark blue, almost transparent, like a cluster of ghost fire, constantly changing and distorting, more than three feet above the ground, suspended in mid-air and slowly wriggling, and emitting a faint light.

"What is this?"

Qi An leaned over curiously, and circled around the strange object a few times, only to see that the thing seemed to be composed of a translucent dark blue mist, like a cluster of dancing flames.

Qi An circled around it a few times, and he couldn't see the slightest clue. However, after careful observation, he found that although this object resembled a flame, it did not emit the slightest heat, but revealed a trace of cold chill, making the surrounding air even more bitter and unspeakably weird.

"Is this a treasure?" Qi An muttered softly, and then shook his head in denial: "It's not like it! It's not like it at all! It's a bit like a legendary spirit soul, but the soul is illusory and formless, and the human eye can't see it at all, but I can see this thing clearly!"

Qi An couldn't think of an answer even if he wanted to break his head, but he was extremely curious, and he always felt that this strange thing had an inexplicable attraction to him, as if it came from the depths of his soul, so he got closer and closer, almost to the flames.

After all, Qi An was young, less cautious and steady, and more often acted on emotion, and under the influence of curiosity, he wanted to figure out what this thing was, so he stretched out a finger, slowly, slowly, touched this translucent mist that was constantly changing and writhing.

"Boom ——!"

The moment Qi An's fingers came into contact with the blue flames, the entire underground lake seemed to shake, and the faint flames suddenly wrapped around Qi An's fingers, turning into a blazing torrent, and swished down the fingertips into the body, scurrying along the arms in the meridians, it felt like magma flowing in the body, which made Qi An extremely painful, and couldn't help but let out a miserable wail, just in the blink of an eye, he fainted in pain.

However, as soon as he fainted, he was awakened by the pain, and Qi An's consciousness seemed to be torn apart by a pair of invisible hands, shattered into thousands of pieces, and then crumpled into a ball and fused together, repeatedly switching between lucidity and drowsiness, all because of the unspeakable severe pain. Countless hot and fiery needle-like lines of fire are scurrying around in the meridians of the body, brutal and ruthless, wreaking havoc, as if countless red-hot soldering irons are embedded in the body, and the muscles, bones, skin and flesh seem to be about to burn, from the inside out, as if they have been subjected to the most inhumane torture in the world.

Qi An curled up and fell on the ice, his skin was weirdly red and shiny, and the blood vessels were bulging one by one, as if they were about to crack at any time, giving people the feeling of being a cooked prawn, and the heat that revealed the skin quickly melted the ice, turning the ice into water, and the water was quickly evaporated into mist, Qi An's thin body was covered in the mist, and he didn't know whether he was alive or dead.

After a long time, the fog gradually dissipated, and a large crater was obviously recessed in the center of Iceland, and the bottom of the pit was significantly lower than the lake level, and Qi An's naked body lay motionless in the pit, and the rags on his body had already been burned to ashes by the high temperature emitted from his body, and evaporated with the ice water.

Qi An's eyes were closed, and even his breathing stopped, but his heart was still beating slowly, and his hands and feet would twitch once or twice from time to time.

I don't know how long later, with a "Ahh

In fact, at this time, his body was already fine, but the burning pain that penetrated deep into the bone marrow was still deeply imprinted in his brain, that is, there was no real pain in his body, but the memories of severe pain still remained in his mind and did not dissipate, creating a perceptual illusion, thinking that he was still suffering, and it was only then that he let out a meaningless wail.

However, this illusion of perception soon disappeared with the passage of time, Qi An's consciousness gradually became sober, he opened his confused eyes, looked left and right, and suddenly found that the light around him seemed to be much brighter, and he could see the mountain rock wall at the edge of the lake from a long distance, not only that, but even the originally dark lake water became clear, and he could even vaguely see the bottom of the lake, which was not as deep as he imagined, at most only about two feet.

"This ...... , my eyesight has increased?" Qi An quickly reacted, it was not that the light had become brighter, but that his ability to see had improved.

"What the hell happened?"

There was no answer, everything that happened just now could not be explained by Qi An's experience, and he didn't even know what kind of existence the translucent dark blue flame was at the bottom. He only remembered that the moment the ghost thing came into contact with it, it was like a living thing, and it burrowed into his body with his fingers, and then made his life worse than death.

Qi An spread out his hands and looked at it carefully, it seemed that there was nothing abnormal, and the burning sensation in his body disappeared completely, everything seemed to be a nightmare.

"It can't be a hallucination!" Qi An denied in his heart, and the inexplicable enhancement of his eyesight seemed to be related to what had just happened.

"Let's recover our strength first! There are likely to be other dangers in this strange place, and I must make sure I have enough combat power to deal with them!"

The quickest way to recover his physical strength is to meditate and cultivate, Qi An temporarily put the strange flame out of his mind, sat directly on the ground, and quietly operated the foundation building method of the Seven Absolute Sword Techniques. However, this time it was different, when he inhaled a deep breath of cold air from his nostrils, passed through his lungs and then dispersed into his limbs, it was unprecedentedly smooth, without the slightest sense of blockage, and then he felt it carefully, and suddenly felt that the pores of his whole body were open, cool and comfortable, and even with his breathing, there was a faint imperceptible airflow in and out of the body, and the whole body was comfortable.

Qi Anmeng's eyes widened, and he roared incredibly: "Innate perfection, all the tricks are clear?"

The simple eight words represent a realm, and this is the limit that a martial artist dreams of, a martial arts master!

Most people who practice martial arts know that there are thousands of meridians and acupuncture points in the human body, and if they can be opened up in turn, they can breathe without relying on the mouth and nose, and with the orifices, which is the innate realm.

It is said that when human beings are conceived in the mother's body, the meridians and points in the body are unblocked, so that they can absorb nutrients in the mother's amniotic fluid to grow, which is congenital breathing; when the baby is born, most of the points will contract and close, and many meridians are also blocked and blocked, so they will use the mouth and nose to breathe, which is the acquired breathing.

Heaven and earth are filled with all kinds of gases, there are clear and turbid, what is good for the human body is called clear gas, and what is harmful to the human body is turbidity. Qing Qi can enter the acupoints through innate breathing and circulate in the meridians, but acquired breathing does not have this effect, because most of the breath from the mouth and nose is turbidity and cannot enter the meridians, and most of it is only turned around in the lungs and then discharged. Therefore, if you want to absorb a large amount of pure qi that is beneficial to the human body, you can only return from acquired breathing to innate breathing, and the prerequisite for innate breathing is to open up the meridians and acupoints of the whole body.

Several cultivation steps of martial artists, the first step is easy to forge muscles and bones, the second step is to wash the marrow and change blood, and the third step is to strengthen the pulse and pass the knack, only by completing these three steps in turn, can we reach the innate consummation realm of all the knots and veins. Among them, the third step is the most difficult and time-consuming, and there are countless people who practice martial arts, and there are not many people who can do it.

Qi An Tianzhong's qualifications, at the age of ten, began to practice with the crippled heart method from his father's mouth, and in less than three years, he completed the easy tendon forging and bone washing and marrow exchange for blood, but when it came to the third step of strengthening the pulse and passing the knack, he initially estimated that it would take three or four years to achieve it at the earliest, which showed its difficulty.

However, Qi An never expected that he would suddenly reach the level of knowing everything, and inexplicably promoted to the Innate Martial Sect, which was completely like a dream, it was incredible.
