Lin Li was shocked by this strange karst cave, and Lin Li had been to some places of interest for many years, but most of them were man-made landscapes that had been transformed or created by people, and the wonders and wonders carved out by nature in front of him could not be compared.

Lin Li walked past the transparent milky stones and found that most of this underground karst cave was original, only a few places were transformed by the Lin family's generation in the way of cultivators, and the smooth boulders behind him emitted incandescent light from the strange and transparent milky stones and finally illuminated in the center of the underground karst cave, Lin Li came to the center of the underground cave under the guidance of the incandescent light, and the incandescent light just shone in a round pool in the center.

When Lin Li walked in, he saw clearly that there was a gray-white liquid in the round pool with a diameter of about one meter, accounting for two-thirds of the round pool, emitting a dull gray-white halo under the illumination of incandescent light, and there were all kinds of strange stones around the round pool, Lin Li knew that the round pool in front of him was the destination of this trip.

In the parchment map, it is recorded that the location of the second inheritance place is an underground karst cave, which originally accumulated and changed over a long period of time to produce a kind of leyline spiritual milk, and this earthly leyline spiritual milk is of great help to the monks of the body refining realm.

Therefore, after being discovered by the Lin family's generation, they took this leyline spiritual milk as the center, pulled the surrounding leylines here, and set up a gathering lock spirit array, so that this leyline spiritual milk will continue to be produced, even if the earth enters the end of the law era, but this leyline spiritual milk will still be slowly produced, but the output has declined seriously.

This sheepskin map was passed down from generation to generation by the cultivators of the descendants of the Lin family, and the ancestors of the descendants did not fill in a lot of notes on the sheepskin map, so Lin Li learned from it that since the end of the Dharma era, the production of this leyline spiritual milk has dropped to a hundred years before it reaches one-third of Yuantan.

Looking at the extra one-third of the leyline spiritual milk in front of him, it is not difficult to guess that this should be the "credit" of the old man Lin Zhenying, after all, Lin Zhenying is the first cultivator of the Lin family to practice to the Great Perfection of Qi cultivation in thousands of years, seeing this, Lin Li is not pretentious, took off his clothes and jumped directly into the pool.

In the round pool, Lin Li just touched the leyline spiritual milk, he felt that these milky white leyline spiritual milk seemed to have life, and began to actively wrap himself, the sheepskin map recorded that this milky white leyline spiritual milk is the essence of the earth's leyline condensation, it can not only wash the meridians and refine the marrow, but also moisturize the meridians to repair the damage, it can be said to be one of the most suitable heavenly treasures for cultivating the fusion realm, seeing the earthly vein spiritual milk actively wrapping itself, Lin Li hurriedly transported the Aoki Transformation Determination Exercise, and began to absorb the leyline spiritual milk in the body.

Before, Lin Li's practice was to use the aura in the spirit stone to wash away the siltation in the meridians, so there was some residual siltation, and the meridians were also partially damaged, especially the three meridians of the Shaoyang gallbladder meridian, the Shaoyin kidney meridian, and the sun bladder meridian, because the vein congestion was more serious, so the time to be washed by the spiritual qi was also the longest, and the damage caused was more serious than that of other meridians.

Lin Li used the Aoki Transformation Determination Technique to absorb a palm-sized piece of leyline spiritual milk into his body, and this leyline spiritual milk instantly turned into wisps of gray-white halo after being inhaled into his body by Lin Li, and then under the leadership of Lin Li's spiritual sense, he came to the damaged meridians, and then the milky white halo attached to the damaged parts of the meridians as if it was alive and began to repair.

After a while, the halo of milky gray white light disappeared, and Lin Li's damaged meridians actually recovered as before, seeing that the effect was so significant and remarkable, Lin Li ran the absorption speed of the Aoki Transformation Determination Exercise to the maximum, and began to absorb a large amount of earth vein spiritual milk.

A large amount of earth vein spiritual milk entered the forest stereo and internalized into streams of gray-white halo, under the leadership of Lin Li's spiritual sense, it spread out in the meridians and flew towards the damaged meridians, and the original faint remnants of the sporadic accumulation in the Lin Li meridians were also washed away by the gray-white halo in an instant, and the injured meridians also recovered under the action of this gray-white halo, and made the meridians more tenacious.

The spiritual sense looked inside, and found that all the meridians had been repaired, and only the faint remnants of the sporadic accumulation had been washed away, and then it was time to start the second step of refining the meridians in the Enlightened Light Realm.

At this time, Lin Li opened his eyes and checked the content of this leyline spirit milk, even if he used it to repair the meridians and consumed a lot of earth vein spirit milk, but there was still a large amount of earth vein spirit milk in the round pool, and when he saw this, Lin Li put his mind at ease, and then began to practice the second step of the Kaiguang Realm.

Lin Li began to melt the gray-white halo into the meridians, which was used to strengthen the toughness of the meridians, so as to achieve the purpose of refining, originally according to the normal cultivation, Lin Li needed to spend nine to ten spirit stones to quench the meridians, which was not only time-consuming and labor-intensive, but also Lin Li did not have so many spirit stones in his hands, and Lin Zhenying left only one spirit stone left for Lin Li to practice, fortunately, there was this leyline spiritual milk that Lin Zhenying had prepared for Lin Li in advance.

This leyline spiritual milk can not only repair the damage of the meridians, but also quickly refine the meridians, saving effort and time, not only that, but even the next stage of cultivation in the body refining realm, this earth vein spiritual milk can also be used, Lin Li had to sigh that this earth vein spiritual milk is not only amazing, but also has a wide range of uses, it is really worthy of the dream of the monks in the body refining period.

The speed at which the earth vein spirit milk was refining the meridians was several times faster than the speed at which Lin Li used the spirit stone to wash away the meridian siltation, not only that, but there were no sequelae left behind such a fast speed to refine the meridians, and Lin Li enjoyed the pleasure brought by refining the meridians.

I don't know how long it took for Lin Li to wake up from his meditation, the twelve meridians in his body have been refined, the spiritual sense has swept through it, there is not a trace of silt and dirt from it, and the twelve meridians have shown a trace of crystal clear feeling, Lin Li knows that the second step of this opening light realm has also been completed, and the next step is to sprint to the fusion realm.

After taking a look at the content of the leyline spirit milk, after the tempering of the meridians just now, Lin Li had already used up one-third of the content of the entire Yuantan, and seeing that there were still a lot of earth vein spirit milk, Lin Li was ready to start sprinting to the fusion realm.

In the Aoki Transformation Determination Method, it is recorded that the practice of refining the three realms of the body is basically based on the development of the dantian as the core, and then through the developed dantian to strengthen itself, in the realm of enlightenment, it is necessary to open the upper dantian at the center of the eyebrows, so as to condense the sea of consciousness, condense the spiritual sense, and then use the spiritual sense to control the spiritual energy to wash the meridians, so if you want to enter the cultivation of the fusion realm, you must develop the middle dantian in the heart socket, so as to refine the blood and qi to impact the acupoints and develop the potential.

Lin Li had already known through the Aoki Transformation Determination Exercise that the first step to enter the fusion realm was to open the middle dantian in the heart socket, and after getting ready, Lin Li first manipulated the spiritual consciousness to find out the specific location of the middle dantian in the heart socket, and then manipulated the spiritual consciousness to introduce the leyline spiritual milk into the middle dantian in the heart socket.

It is recorded in the Aoki Transformation Determination Exercise that in order to break through the realm, it is necessary to absorb a large amount of spiritual energy and the middle dantian to promote the middle dantian, so that it can give birth to the "descending palace", so that the next step of cultivation can be carried out, because there is no spiritual stone, so the earth vein spiritual milk is used instead of the spiritual energy to promote the middle dantian.

The middle dantian of Lin Li was nourished by a large amount of leyline spiritual milk, gradually changed, and began to absorb the leyline spiritual milk independently, just like Lin Li's dantian opened up the sea of knowledge, the current middle dantian began to slowly expand while absorbing the earth's vein spiritual milk, this leyline spiritual milk is really worthy of being a heavenly material and earth treasure, which greatly shortens the time to promote the middle dantian, and also increases the connotation of Lin Li, so that Lin Li's cultivation in the next fusion realm can be much easier.

The middle dantian is enlarged little by little, and each time it is a little bigger, it takes a lot of gray-white halo produced by the leyline spirit milk, and finally in the middle dantian, it stops when it is stretched to the size of a palm, indicating that the limit of Lin Li is here, and the size of the middle dantian is closely related to everyone's qualifications, talents, bloodlines, and so on.

The bigger the expansion of the middle dantian, the better the palace descending background will be spawned, which will be of great help to the next practice, ordinary people only rely on their own efforts, usually only two or three thumb-sized degrees, and Lin Li is more special, there is a Gu poison in front of the "change" bloodline, and after the Qinglian seed "increases" the qualifications, the two add up to the extent of the size of a fist, but with the help of the earth's vein spiritual milk, this kind of natural material and earth treasure, it is forced to the size of a palm.

Lin Li didn't know how great an achievement he had with a palm-sized dantian, he only felt that it was almost time, so he retrograde a mouthful of essence blood from the twelve meridians and poured it into the palm-sized middle dantian, and after being irrigated by Lin Li's essence blood, the middle dantian began to burst out, emitting blood-colored red light, wrapping the entire palm-sized middle dantian, Lin Li saw this, and then put the gray-white halo generated by the leyline spirit milk into the middle dantian wrapped in blood-colored red light, which was used to speed up its catalysis.

Time passed little by little, Lin Li had invested a large amount of the gray-white halo produced by the leyline spirit milk, but the middle dantian wrapped in blood-colored red light still did not react, Lin Li began to be a little anxious, because last time there was Lin Zhenying on the side to guide, it was easy to open the light successfully, and this time everything could only rely on himself, so Lin Li couldn't help but be a little anxious.

After a while, seeing that the middle dantian wrapped in blood-colored red light had not yet reacted, Lin Li manipulated his spiritual sense to approach the middle dantian wrapped in blood-colored red light, ready to investigate, but it was a coincidence that as soon as Lin Li's spiritual sense approached the middle dantian wrapped in blood-colored red light, a large amount of blood-colored red light burst out, and then an explosion occurred, and Lin Li's spiritual consciousness was too close to dodge, and was directly blown into pieces.

Suddenly, Lin Li's mind was blank, buzzing, this was the first time since the birth of Lin Li's spiritual consciousness that he was forcibly dispersed, and it took a long time for Lin Li to get rid of this kind of broken spiritual consciousness, and sure enough, there were dangers everywhere along the way, and if he was not careful, he could kill himself, it seemed that he must pay attention in the future, Lin Li secretly sighed.

Waiting until the shock at the middle dantian had ended, Lin Li dared to manipulate his spiritual sense to check it, and the middle dantian in his heart had disappeared, and in its place was a circular space with a barrier, Lin Li knew that this was the descending palace, which meant that Lin Li had entered the cultivation of the second realm fusion realm of the refining body.

And the large amount of blood-colored red light in the space all dissipated, leaving only a blood-qi vortex with a faint red light, the blood qi required for the fusion cultivation of the second realm of this refining body was obtained from this blood-qi vortex, Lin Li manipulated the spiritual sense to catalyze this blood-qi vortex and began to try to cultivate the fusion realm.

The cultivation of the fusion realm is much more difficult than the cultivation of the enlightened realm, because in the fusion realm, it is necessary to open up all the acupuncture points of the human body, and there are about 52 single acupoints, 309 double acupoints, and 48 extra-meridian acupoints around the human body, and a total of 409 acupuncture points, all of which need to be opened.

In addition, there is a "Ren Pulse" in the center of the front of the body, and there is a "Du Pulse" in the center of the back of the body, each with a special meridian that runs through the whole body, and these two meridians are free between the Enlightenment Realm and the Fusion Realm, and these two meridians must be opened before entering the Fetal Breath Realm, otherwise it will be a great obstacle to the next cultivation.

It is recorded in the Aoki Transformation Determination Method, there is no order that must be followed to open up the acupuncture points in the fusion realm, and it is only divided into four major systems according to the acupuncture points in the human body, which are the head acupoints, chest and abdomen acupoints, upper limb acupoints and lower limb acupoints, and each time the acupuncture points of a system are opened, the practitioner will get the comprehensive increase of the acupuncture points of the system and strengthen himself.

For example, opening up all the acupuncture points in the upper limbs will greatly increase the strength of the cultivator, and it is even rumored that talented cultivators will generate special natural supernatural powers after all the acupuncture points in the large system are opened, so the cultivator can open up the acupuncture points he currently needs on his own, so as to obtain the corresponding power.

And the power of qi and blood generated by the palace that has just been catalyzed is the most prosperous, and it can easily open up an acupuncture point, Lin Li has already known it from the Aoki Transformation Determination Method, so he immediately manipulated the spiritual sense to extract all the blood and qi in the blood and qi vortex from the descending palace, and followed the meridians to the Baihui acupoint on the top of the head, which is the most critical acupuncture point in the acupuncture point system of the head, so Lin Li was the first to open it.

The surging blood qi directly crashed into the clogged and closed Baihui acupoint, and the blocked silt was vulnerable under the turbulent blood baptism, and instantly turned into nothing, and the Baihui acupoint on the top of the head was instantly washed away by the blood qi.

After opening up all the acupuncture points of one branch in the acupuncture point system of this head, Lin Li suddenly felt a feeling of refreshment.
