After entering the car, Ling Feng's eyes lit up, from the outside, the carriage could only accommodate a few people, but he didn't expect that there was indeed a hole inside, the size of several rooms, and continued to walk to the depths of the carriage, bypassing the layers of goods, but saw several people leaning on the corner of the carriage, it seemed that they had also spent money to take this ride.

Found a clean place, Ling Fengpan sat down, this will be a person in a foreign land, but his heart is not as lonely as he imagined, after all, he lives alone on weekdays, and now he is just a different place for himself.

After sitting down for a while, the noise around him gradually subsided with a stir, presumably the carriage had left the west gate.

Sitting in the car, bored, Ling Feng suddenly remembered that when they were separated, Kun Peng had said that there was an introductory scroll as a gift, so he opened the burden with anticipation.

With a slightly musty quaint smell rushing towards him, a roll of slightly yellowed parchment paper appeared in front of him, Ling Feng couldn't wait to untie the ribbon and spread it out, only to see a few large characters at the front of the volume "The Art of Inner Vision", followed by two lines of small characters "The road of cultivation, difficult steps, take the world, circulate in the body, changeable, endless, want to achieve something, the beginning of internal view".

Ling Feng stared at these words, muttering repeatedly in his mouth, the beginning of his inner vision... Does it mean that you have to look inside your own body? It sounds a little strange, but I really can't think of any other meaning.

Ling Feng continued to look behind with questions, and he didn't know how long it took, with a few coughs, he pulled back from these words, he was too fascinated by it just now, and he accidentally fell silent in this scroll.

Ling Feng looked around for the sound, only to find that there were two women and a man leaning weakly against the wall in the car, their faces were pale, obviously suffering from minor injuries.

He didn't care, just continued to stare at the book, recalling what was unique just now, it turned out that the previous few sentences were just a general outline, and the back was the outline of the cultivation method of the art of inner vision and some basic common sense, from the sheepskin scroll, the art of inner vision is actually the most basic practice of cultivating magic and refining the body, and it is also the most important part, only by learning the art of inner vision, can you detect the situation in the body, whether it is flesh and blood, muscles and bones, meridians, or energy flow, so that it can be effectively exercised and controlled.

The art of inner vision is divided into three layers, the first level is the first vision, the so-called first vision, is to separate the whole mind, abandon all external interference, and sink into the body.

The second level is endoscopic, as the name suggests, and when you reach this level, it is like having a pair of eyes in your body, and you can see the state of flesh, blood, meridians, and energy flow in your body.

The third layer is the release, after understanding one's own situation, it is to feel the flow and change of all the energy in the outside world, because there is always a time when one's own energy is exhausted, and it will be a slow process when it is generated, therefore, when fighting, it will often absorb the energy of heaven and earth for its own use, so that it can delay time, and can increase its power, so it is an indispensable part to feel the energy of heaven and earth when feeling the divine consciousness is released.

Ling Feng put down the book, his eyes were cold, this parchment was obviously not directly teaching magic cultivation methods, but it was very important, if he couldn't deeply understand his own situation and feel the energy of heaven and earth, how could he use and improve, I am afraid that he would not be able to release it, even if he could barely use it, it would be like borrowing the power of strange stones before, unable to control the intensity, bringing a huge load to the body, causing irreparable damage.

From this point of view, this first step seems simple, but it is not easy.

After reading through the scroll, Lin Feng also knew the cultivation method in his chest, but he didn't know if he could succeed, thinking of this, he closed his eyes, calmed down, and tried to make his state of mind slowly calm down, and felt the situation in his body according to the recorded method, and I don't know how long it took, all the external sounds gradually disappeared, and the distracting thoughts in his heart were also eliminated, as if the soul had separated from the body and turned into nothingness.

Time passed minute by minute, but the darkness in front of him suddenly became clear, Ling Feng looked at himself, but the scene in front of him shocked him, he turned into a ball of light suspended in a huge space, and this space was clearly composed of his own flesh and blood, and he could even feel the contraction and trembling of his flesh and blood, "Hum" Ling Feng only felt that his head was trembling, everything in front of him was so unreal, it had completely subverted his worldview, but despite this, Ling Feng was still moving slowly.

Suddenly, he found that not far from him, there was a gray pipe several times thicker at the intersection of the intricate bright red pipes, and a little fluorescence was escaping everywhere with the pipe, Ling Feng's eyes lit up, if he guessed correctly, this should be the divine vein recorded in the scroll, so he followed all the way up, and made up his mind to see what the end of this divine vein was.

According to what I have seen in the records, there are generally 12 major meridians in the body, one divine vein, and the meridians, together with the major organs and limbs of the body, meet in the chest cavity, and then merge into the divine domain of the brain from the divine veins.

The meridians will slowly evolve and change with the continuous improvement of levels and abilities, and the most basic change is to continue to thicken and toughen, so that more energy can circulate, and at the same time, it can withstand the pressure of purer energy.

And for a cultivator to reach a higher level, in addition to diligence, bloodline and other reasons, it is often talent that plays a decisive role, and the divine vein is the best proof of talent.

The divine vein is also called the spiritual root, the talent is divided into high and low, and the spiritual root is naturally divided into good and bad, from low to high, it can be divided into waste spiritual root, miscellaneous spiritual root, five-color spiritual root, alien spiritual root and heaven and earth spiritual root, all of them have the heavenly spiritual root is the anti-heaven demon who seized the heaven and the earth, and the earth spiritual root is second; Ice, this kind of spiritual root is also the existence of one in ten thousand; the five-color spiritual root represents the basic attribute of the five elements, and if you have one of the five colors, the attribute magic will be easier to master, and the power is several times more than that of other attribute magic; the miscellaneous spiritual root refers to the inferior spiritual root with impure spiritual root attributes, mottled and impurities, and the magic power used by this spiritual root will be greatly reduced, and the level of self-cultivation will not be too high; as for the waste spiritual root, you can only feel the energy of heaven and earth and use simple magic.

......

"Bang!" A muffled sound came, and when he thought like this, the light cluster he had turned into seemed to be blocked by an invisible force, and Ling Feng came back to his senses, and there was actually a light curtain in front of him, the light curtain was flickering and dazzling, so he had no way of knowing what was on the other side of the light curtain, and from under the light curtain extended a pillar of light that was also shining with bright light, and the other end of the light pillar was connected to the gray divine vein.

It's just that... It's just that what makes Ling Feng strange is that the pillar of light seems... It seemed to be devouring the divine vein, gradually the gray color disappeared little by little, and the pillar of light increased little by little, although the speed could no longer be described as slow, in Ling Feng's opinion, the entire divine vein seemed to be thousands of zhang long, and the speed at which the light spot spread was only half an inch after a long wait, but what was certain was that the divine vein was really being devoured.

Seeing this, Ling Feng became more and more puzzled in his heart, he clearly remembered that the gray spirit root should be a waste spirit root, and the miscellaneous spirit root was as dull and mottled as silt, while the five-color spirit root gold, wood, water, fire, and earth corresponded to golden, turquoise, light blue, red, and ochre brown respectively, and the thunder and ice of the alien spirit root were indigo and white, and the spirit roots of heaven and earth tended to be transparent.

But what the hell is going on in front of him, is there a mistake in what the scroll says?The spirit root can actually be preliminarily determined by the technique of inner vision, because of the principle of closeness, the color of the spirit root will be biased towards the attribute energy of magic, then Ling Feng must be a waste spirit root, although this is frustrating, but the fact is that it is so, and manpower is naturally impossible to change.

The spiritual root is irreversible like a talent, but now his gray spiritual root is covered by an unknown pillar of light... This situation was not recorded in the scroll, and he naturally couldn't figure it out, since he couldn't figure it out, then don't think about it, let it be, he decided in his heart, Ling Feng's mood was suddenly relieved.
