said that Li Xuanyu listened to the ins and outs of Zhang Xian's provocation of Qin Ziyun, and smiled rarely, no one knew what Li Xuanyu was thinking, and actually agreed to accept Zhang Xian as an apprentice.

"What...... Fairy Sister, did you agree?"

These words made Zhang Xian stunned, his mind was full of question marks, Li Xuanyu actually accepted him as an apprentice? Did he hear it right, this inexplicable coincidence, there was actually an extra master?

But he didn't want to really apprentice, and he didn't want to go to the Shangqing Dao, what kind of thing is this Nima? Could it be that the immortals act like this, is it so inexplicable?

It seems that he also wrote this in the book, and the actions of the world's masters are often ordinary people who can't understand it, and they don't play cards according to common sense, which is really an evil belief.

However, listening to Zhang Xian's words, she was still called Sister Fairy, Li Xuanyu frowned slightly, not used to this kind of men's intimate tone, her eyes were a little more serious, and she said: "It's called Shizun, and respecting the teacher is the basic." ”

Raising his hand and pointing, the void drew a talisman, and an arc of lightning slashed across Zhang Xian's body.

"Ah......h

Zhang Xian immediately screamed, trembling and convulsing with electricity, and almost didn't scold, this Nima didn't accept apprentices before, and now he is going to be forcibly accepted, the bitterness in his heart, he is too difficult.

But in the face of Li Xuanyu, he really couldn't beat him, the hero didn't eat the loss in front of him, he thought, first agreed, and then found an opportunity to slip away, and hurriedly looked honest and serious: "Yes, yes, it's Shizun." ”

Li Xuanyu nodded slightly, didn't say much about his cold temperament, and continued to walk forward.

Zhang Xian hurriedly followed, honestly, really like an apprentice.

The two of them kept walking like this, through the mountains and forests, and went to the east, and they didn't stop resting on the way, nor did they eat or drink, and they walked for dozens of miles, and it was already afternoon, and they entered a county next door to Baiyan County, called Fan County.

However, he did not go to the county seat of Fan County, but went on the official road, walked in the other direction, and walked until the evening, not in front of the village, not in the back of the store, Li Xuanyu was also very casual, just settled on the side of the road, sat on the ground, closed his eyes and recuperated, and asked Zhang Xian to pick up some firewood.

Zhang Xian was depressed, so he had to go to collect firewood, burn a bonfire, and look at Li Xuanyu's appearance, he was going to meditate all the time tonight.

He wanted to find a chance to talk, this immortal master was too cold, he didn't speak, he didn't eat or drink, he walked for a day, and this sitting had to be a night, and he was really not a mortal.

He didn't eat for lunch, and he didn't eat at this time, so he took out a sip of water and drank it, and said with a smile: "Master, please drink water." ”

"I breathe and don't have to drink. ”

Li Xuanyu opened his eyes, and in a clean and cold tone, he immediately slapped the sword box behind him, opened it, took out a bottle, handed it to Zhang Xian, and said, "This is a bottle of Bigu Dan, you are hungry, eat this for the time being." ”

"Bigu Dan, Mo is not an elixir!"

When Zhang Xian heard this, he was immediately overjoyed, quickly took the bottle, carefully opened the cork and poured out one, not in a hurry to eat, but carefully watched the elixir.

Seeing this, Li Xuanyu shook his head slightly, and said lightly: "Secular people admire Fang Xian, superstitious ghosts and gods, and believe in the elixir of magic, but in fact, there are no ghosts and gods at all, and there is no so-called elixir. ”

"Oh, it's made of nuts. ”

Zhang Xian reacted, he thought it was the legendary elixir, so he quickly tasted one, it was really nutty, as well as ginseng, Ganoderma lucidum, cordyceps, deer antler velvet and so on.

He used to be in the Guogong Mansion, and he often went to the pharmacy to get medicine, so he was very familiar with these tastes, plus his current five senses are sensitive and his sense of taste is also very sensitive, and he knows what it is when he eats it in his mouth.

However, these precious medicinal materials into the pill, for ordinary people, can also be called an elixir, eating one is a great tonic.

Li Xuanyu said again: "This Bigu Dan is rich in medicinal properties and contains a lot of substances, you take one a day as a health condition, you can consolidate the foundation and cultivate the yuan, but the stomach is hungry, and you also need a balanced diet." ”

"yes, I see. Zhang Xian nodded, put away the Bigu Dan, his mind moved, and he began to talk, and asked, "Master, where are we going, are we going back to Shangqingdao?"

"I want to continue to track down the Tianmen behind Qin Ziyun. Li Xuanyu said, "This journey is on the way, I will take you to Hanguan City in Yunan County, I will live in the city for a few days, after a few days, we will go out of Hanguan and branch ways, you go to Geshan alone, I will have someone pick you up." ”

"Oh, I'll go to the Pavilion Mountain by myself. ”

Hearing this, he was stunned, but he was overjoyed in his heart, isn't this the time for him to slip away, but Li Xuanyu's level of existence, the Tao is powerful, and it is mysterious, and he can cast a spell at a glance, and he is worried that he will not be able to run away.

His mind moved, and he pretended to be afraid and said, "Master, Fairy Qin has remembered my soul, if you are not there, what if she finds me?"

Li Xuanyu raised his hand and pointed at it, drawing talismans in the void, and the illusion flashed in front of Zhang Xian's eyes, only to see a bird-shaped seal inscription printed into his eyebrows.

"This talisman can cover yin and yang, when you encounter danger, you can also concentrate your thoughts, visualize this rune, and think of me in your heart, I will receive your thoughts, and save you with the yin god, but you must not be careful, don't read me until it is critical, I may be busy with other things." ”

"Uh-huh, I see. ”

Zhang Xian nodded hurriedly, pretending to be curious, this spell is really mysterious, but his mind turned quickly, Li Xuanyu left a rune, which also means that he can't escape, unless he breaks this rune, maybe ...... Maybe he can try the art of the living dead, and bury the living to avoid calamity.

Out of Hanguan and parting ways with Li Xuanyu, he has time to try, and now, since he worships an immortal master, he can just ask for advice.

He put on an appearance of humbly seeking the Tao and asked, "Master, can you tell me about the realm of cultivation, I have always read books by myself, practiced indiscriminately, and I don't know how to go step by step. ”

"Well, if you have any doubts about the Dao, you can ask me. ”

Li Xuanyu nodded, this apprentice's talent is extraordinary, if he can practice so modestly, over time, he will become a great weapon, and said: "Cultivation is divided into two realms: innate and acquired, and it is divided into three layers: upper, middle and lower. ”

"Let's talk about the acquired realm first, which means that after a person is born, from the moment of birth, the root bone of a person has been fixed, such as the power of Jiujun described in the "Martial Classics", which is the limit of the acquired mortal, everything has a limit, the root bone of a person is a person, and the root bone determines the limit. ”

"Martial arts practice physique, qi and blood, and Fang Immortal cultivates essence and soul. ”

"The lower layer of acquired martial arts is the muscles and bones of the outer family, the middle layer is the internal organs of the inner family, and the upper layer is the strength of the inner family, the integration of the inside and the outside, and the combination of rigidity and softness.

"The lower level of the acquired immortal is to practice refinement, and energy is the foundation of people, to strengthen the body, and to consolidate the foundation and cultivate the yuan. ”

"The middle-level practice of refining and refining qi can be regarded as a first glimpse of the doorway, and you can practice the mantra and chant the scriptures. ”

"The upper level practices Qi Huashen, this can be regarded as a small success of Taoism, and you can draw talismans and cast spells. ”

"However, the human body is a whole, martial arts and immortal law are all connected, the lower level of the outer family, is also to strengthen the body, consolidate the foundation of the Yuan, recuperate, the middle level of the inner family, but also from the surface of the body deep inside, practice a state of mind, the upper level of the strength, out of the spirit, is also refining the gas and the gods, and said to the gods, I watch your daily actions, there is already a bit of rhythm, you should have some understanding. ”

Zhang Xian immediately understood, and immediately understood, it turned out to be the case.

No wonder when he practiced boxing, he unconsciously realized the transformation of strength, and when he practiced internal strength, he visualized Ruilong, and as soon as he practiced, it turned out that the realm truth was the same, and Li Xuanyu saw his realm cultivation by watching his body movements.

Li Xuanyu continued: "When you reach the upper level of the day after tomorrow and break through the shackles, you can step into the innate realm. ”

"The congenital, as the name suggests, before a person is born, is a mass of flesh and blood in the womb, this is the congenital, the innate contains the true meaning of life, full of infinite changes, return to the congenital, reshape their own flesh and blood with practice, take off the mortal fetus, modify the root bones, and break the limit of the acquired mortal, so it is called an immortal. ”

"However, the path of cultivation is to follow the laws of the human body, and before the innate realm, there is also a transition, called Bao Dan. ”

"There are two conditions for holding Dan, one is the body qi and blood, and the other is the spiritual soul, the two are fused, the Taoist book says: Yin and Yang are mixed, and the day after tomorrow is perfect, which is called Dan ripe. ”

"Let's talk about the body's qi and blood first. ”

"The human body qi and blood are derived from the bone marrow, the infant period after birth, the closest to the congenital, the bone marrow is bright red, because the baby's life vitality is the most active, as the baby grows up, the body bone is shaped, the older the age, the poorer the life vitality, the bone marrow will become the color of old yellow. ”

"Through practice, the body functions are active to the peak, through the combination of strength, rigidity and softness, the kung fu is practiced into the bone marrow, so that the bone marrow is active, as if returning to infancy, deriving the baby-like qi and blood, replacing the body's poor qi and blood, this step is called marrow training and blood exchange. ”

"Could it be that it is commonly known as opening up the two veins of Rendu? the acquired cultivation of the twelve canons, and the innate cultivation of the eight veins of the strange scriptures!"

Zhang Xian spoke, he was proficient in medical skills, listening to this realm, he immediately drew inferences, bone marrow hematopoiesis is the backbone, and the middle line of the back spine is the Ren pulse and the Du pulse of the eight veins of the Qi Jing, and the function of these two veins is to manage qi and blood.

"......" Li Xuanyu couldn't help but be silently surprised when he heard this, this apprentice's talent is really extraordinary, and he already understands the truth:

"Yes, the marrow exchange is commonly known in the rivers and lakes to open up the second pulse of Ren Du, the blood is refreshed, not only the enhancement of physical strength, but more importantly, the activity of physical functions, you can eat a sheep, you can not eat for ten days, you can not sleep for a few days, you can also sleep like an animal hibernation, you can not be afraid of ice and snow, you can also endure the heat without sweating, you can heal from serious injuries overnight, you can have clear facial features and six senses, you can turn white hair to black hair, you can have delicate skin like a baby, you can be over sixty years old and your physical strength is not declining, etc. ”

"When you reach this realm, your physical functions are at your peak, and the acquired physical body is already complete, and you are still short of the perfection of your spiritual soul, that is, you can practice your spirit and return to emptiness. ”

"The virtual realm is the time when the true meaning is turned into nothingness, emptying everything, seeing the true self, returning to the womb with a mass of flesh and blood, giving birth to the soul and spirit, to be quiet, to the void, the flesh and blood are chaotic, and the thoughts are endless, in this state, the spiritual thoughts reach the most perfect operation, as if returning to the womb to conceive, grow and grow. ”

"Practicing the marrow and the virtual realm, the two are combined, returning to the ancestral blood, returning to the innate thoughts, the flesh and blood thoughts are mixed together, so it is said that yin and yang are mixed, and it is like a round pill, this is the Baodan, you can understand?"

This is the trick of holding Dan to enter the Tao, but these mysterious truths imply the laws of physiological life, which are not understandable to ordinary people, and Li Xuanyu also tested Zhang Xian to see if Zhang Xian could understand.
