For cultivators in the realm of refining qi, after deriving innate true qi, they are deriving meridians.

There are a total of eight meridians, like vines, that derive and grow from the dantian.

The cultivator's hands and feet have four meridians.

The dantian leads directly to the heart, which is called the heart vein.

From the dantian upwards, through the chest, throat, mouth and nose, to the top of the head, it is called the anterior vein.

From the back of the spine upwards, it leads to the back of the head and the top of the head, which is called the posterior vein.

The last and most important one, which leads from the dantian to the top of the head, is called the central channel.

After a cultivator is promoted to the Qi Refining True True Realm, he consolidates the realm and derives the meridians. Taking advantage of the opportunity to fuse the innate true qi to advance, these eight meridians were derived.

If all eight meridians can be derived, that is the best result. If you can't, then you can evolve as much as you want, and the meridians that can't be derived and generated will be slowly evolved and generated in future cultivation.

Wei Wuji waved his hand and captured more than 300 spirit stones in the air, devoured and inhaled the spirit stones, gathered them in the dantian, and derived the meridians.

The aura and the innate true qi merge to form a majestic force that seeks an outlet for catharsis. First of all, the feet, the innate true qi goes along with the trend, connecting the meridians of the two feet. Then there are the hands, and the true qi runs along the arms, opening up the meridians of the hands.

These four meridians are the easiest to get through, and the vast majority of cultivators evolve the meridians after they are promoted, and that's why they do it. The remaining four meridians will slowly evolve and open in the future cultivation, and the cultivation will take shape. But Wei Wuji was not satisfied, he wanted to continue to evolve and open up the remaining four meridians.

At this time, the aura in the body has been exhausted. Wei Wuji didn't care about the consumption of spirit stones, and transferred the aura of three hundred spirit stones into his body together.

According to the stage of practice, the next meridian to be opened is the heart vein. Wei Wuji's innate true qi was running, gathering spiritual energy, and rushing towards the heart position together.

Bang! A sound came, deafening, and Wei Wuji felt his ears buzz. It was as if there was an invisible stake, striking him the heart, and his eyes were black, and he almost fainted.

"It's amazing, no! I've used so many spirit stones, I have to connect the meridians today!"

Wei Wuji ingested the aura of hundreds of spirit stones into his body, adjusting his innate true qi and rushing towards his heart.

There was a loud bang, and Wei Wuji's body, like a bronze bell, was violently struck.

He shuddered and spurted out a mouthful of blood. The heart is penetrated by the powerful innate true qi, and the dirt that blocks the heart is spurted out of the body with this mouthful of dirty blood. What followed was a refreshing sensation, and the circulation of qi and blood in the whole body suddenly accelerated, whining in the ears.

"Okay, I can hear the sound of my own qi and blood circulation! Wei Wuji felt a burst of excitement in his heart, and continued to evolve and cultivate, opening the next meridian.

Derivation opens up the meridians, which has a great relationship with aura. Ordinary cultivators are reluctant to consume spirit stones like this, they will absorb the spiritual energy between heaven and earth, accumulate dantian, and after it is abundant, it will be derived and opened up to the meridians. The spirit stone is left by his side and used at critical moments.

But Wei Wuji didn't care, the spirit stones that he was usually reluctant to use were prepared for this critical moment, and he didn't hesitate to waste them! He consumed the spirit stones at any cost and inhaled the spiritual energy into his body.

The stage of cultivation should be derived this time to open up the front vein. The innate true qi of the dantian was entangled with the spiritual qi and rushed upward. Wei Wuji suddenly felt that his face was pale, and where his true qi passed, his internal organs seemed to be cut by a knife, and the pain was unbearable.

"My heart has been determined, a little pain is nothing. ”

Wei Wuji operated the Great Wuxiang Refining Mind Technique, cleared his mind and mind, and the pain seemed to be alleviated a lot, and he continued to run the True Qi and impact the front veins.

Finally, the anterior vein is connected, followed by the posterior vein.

Wei Wuji spent hundreds of spirit stones, and the spiritual energy gathered in the dantian, and together with the innate true qi, it drilled towards the spine of his back. He felt like a slender wire snaking upward, strung together through each spine.

Every joint of the spine made a loud noise. Suddenly, Wei Wuji felt that he couldn't shake, and the entire spine of his back, as if it no longer belonged to him, was completely uncontrollable. He ignored the changes in his body and continued to control the innate true qi to extend upwards to the top of his head, completing the penetration of the back veins.

"If you can derive the middle channel and smoothly penetrate it, it can be regarded as the real success of the promotion! ”

Wei Wuji ingested the aura of the spirit stone and began to evolve and impact the midrib.

The central channel is the most difficult meridian to derive and cultivate, and many cultivators have been stuck at this level, and it took several years to finally break through. This is because among the eight veins, the other seven veins are all fixed in position, and the slightest difference varies depending on the height of the cultivator.

The position of the central channel of each practitioner is different, and there is a lot of difference between them. It is recorded in the classics that there are no two central channels in the same position for cultivators in the Qi Refining Realm in the world.

Since the central channel is not the same, the methods of deriving cultivation and opening up penetration, as well as their respective experiences, are also very different. The experience of others can only be used as a reference, not as a standard to be understood and mastered.

Wei Wuji had expected the greatest pain, but when the pain came during the cultivation of derivation, it was not as intense as he expected. Not even as painful as the pulse of his heart, just when Wei Wuji was strange, a vision came, and some hallucinations appeared in front of his eyes.

"According to the accounts of those who have come to open the central channel, some people are in pain and wailing, some people seem to be in a different world, as if they have just woken up from a big dream, some people see their past and future, and some people also see the collapse of this martial arts world. But I saw these humble visions......"

Wei Wuji thought in his heart, ignored the illusion in front of him, and let it change, keeping his mood peaceful, as if watching a play. Finally, the central channel leads straight to the top of the head, breaking the skull upwards and communicating with the outside world.

In an instant, Wei Wuji felt a cool breath falling vertically from the top of his head, as if he had been empowered.

"The central channel has finally been opened!Strange, it's not as troublesome as recorded in the classics?" Wei Wuji completed the passage of the eight meridians and stood up from the bluestone.

Now he was covered in dirt, black and yellow sticky, emitting a foul smell. Ninety percent of the spirit stones were consumed by promotion, and only the last more than a thousand remained. Using more than 9,000 spirit stones to complete the promotion, such a lavish squander, I am afraid there is no precedent in the sect.

Washing away the dirt, Wei Wuji began to test his strength, which was at least ten times higher than that of the Nine Heavens.

In terms of strength, because of his cultivation of the Nine Turns Canglong Gong, his strength in the Nine Heavens was nearly a thousand catties higher than that of ordinary cultivators of the same level. After being promoted to the Qi Refining Realm, his strength was also nearly a thousand catties higher than that of ordinary cultivators!

Moreover, in the cultivation of the Nine Heavens, the body can only inhale the breath and then extract the aura in it. When you reach the Qi Refining Realm, between cultivating and breathing, you can directly absorb spiritual energy from the outside world.

There are ants under the refining of qi, this statement is really true!

Wei Wuji drew his sword in his hand, the tip of the sword pointed obliquely at the earth, and a wisp of headwind rose from the tip of the sword, rolling up the dust on the ground and swaying upward. A strong wind stirred the void air and disturbed the flow, and a long wind suddenly rose and blew in all directions.
