The so-called knot between monks refers to the further condensation of the liquefied mana in the monk's dantian to form a solidified spherical golden pill, which is the most important place for the monk in addition to the soul.

Generally speaking, the mana that can be stored in the solidified Jindan is much more than that that of the liquefied dantian of the foundation building monks, which is also the reason why the mana of the monks in the early stage of the foundation is usually more than ten times deeper than the mana of the Great Perfection in the later stage of foundation building.

However, this situation does not apply to Ren Xiaoyao, who is extremely rebellious among the foundation building monks. Now Ren Xiaoyao, even if he doesn't have a knot, his mana is deep enough to be close to a knotted monk. In other words, the density of liquefied mana in Ren Xiaoyao's dantian is now much stronger than that of ordinary foundation building monks.

Therefore, the process of Ren Yao's knotting is much easier than that of ordinary foundation building monks. Of course, counting the Jin Dan that Ren Xiaoyao wants to condense is not ordinary, and the difficulty in this has risen a lot.

After a qiē was ready, Ren Xiaoyao meditated for seven days and seven nights, carefully recalling the bits and pieces of his journey from the earth to this world of cultivating immortals, connecting the gains and losses, joys or sorrows, and finally, when Ren Xiaoyao's mind became ethereal and only had the idea of knotting, Ren Xiaoyao's gesture changed, and he quickly pinched the magic with one hand.

According to the records of the classics obtained by Ren Xiaoyao, the process of knotting the pill is divided into five stages: the return of hundreds of rivers to the sea, the stimulation of potential, the absorption of pills, the condensation of Jindan, and the easy tendon and the body.

The so-called return of all rivers to the sea is to gather all the mana of the whole body in the dantian.

With the change of the posture in Ren Xiaoyao's hands, all the meridians of Ren Xiaoyao's body, all the mana scattered outside the dantian continued to converge towards the Danzhong like a hundred rivers returning to the sea. In the dantian, the liquefied mana quickly formed a huge vortex, which kept rotating, and became smaller and smaller in the rotation, and the mana became more and more viscous.

The stage of returning to the sea of Baichuan was relatively easy to complete, and it only took Ren Xiaoyao an hour to gather all the mana of his body into the dantian.

When all the mana outside the dantian returned to the dantian, it entered the potential stimulation stage.

I saw that the posture of Ren Xiaoyao's hands changed, the pores of the whole body were dilated, and the meridians everywhere slowly expanded and became bigger, at this time, a large amount of potential poured out from all over the meridians, and was quickly squeezed back into the dantian by Ren Xiaoyao.

In this process, Ren Xiaoyao even deliberately assigned a part of his mana to operate the Eight Veins Flowing Spirit**, absorbing more mana from the environment outside the body and entering the body.

At this time, Ren Xiaoyao's location was the place where the spiritual power of the Cave Heaven Layer and the Cave Heaven Tower was the densest, and the Ninety-Nine Gathering Spirit Array of the middle grade magic weapon level was laid around it. Coupled with the aura overflowing from the overseas immortal island, it can be said that the density of spiritual power in the environment in which Ren Xiaoyao was at this time reached the Cheng dù of the top-grade spiritual vein.

In the potential stimulation stage, the body absorbs mana from the environment, which can not only increase the total amount of mana in the dantian, but also stimulate the body's potential through external aura.

When he absorbed a large amount of mana from all over his body for the first time, Ren Xiaoyao's gesture changed, and he continued to increase his efforts to squeeze the mana from all parts of his body, and continued to guide the absorbed mana into the dantian.

In the process of knotting the pill, the more mana gathered in the dantian, the easier it is to condense the golden pill, and the higher the quality of the golden pill. At the same time, in the process of mana condensation, the more the foundation building monk stimulates the hidden potential of the limbs and bones of the body, the more medicinal effects he absorbs when refining the golden pill, and the better the improvement of his physique, of course, the higher the quality of the golden pill condensed.

However, as the number of absorptions increased, there was not much hidden mana left in all parts of Ren Xiaoyao's body. When Ren Xiaoyao intensified his efforts to absorb the mana that was not already in his body, his body would feel tired and painful.

When Ren Xiaoyao increased his efforts for the seventh time to absorb mana from all parts of his body that had almost dried up, the pain that Ren Xiaoyao endured everywhere in his body was as if he was being cut by a thousand knives. However, no matter how painful it was, Ren Xiaoyao endured it when he thought of the life and death catastrophe he was about to face in a hundred years, as well as the various powerful enemies he could face in the future.

In fact, at this stage, as long as a sufficient amount of mana is gathered in the dantian, it can enter the next stage, thus condensing the golden pill. However, in that case, if the physical potential is not fully developed, it will affect the quality of the Jindan, and the advancement will affect the qualification of future cultivation.

The first is that the monk cannot bear the pain of potential stimulation and ends the potential stimulation process prematurely, so that the mana in the dantian is always insufficient, not enough to condense a lowest-quality golden pill. The second situation is that the monk himself has not reached the Great Perfection in the late stage of foundation building, or the total amount of mana in the whole body is still too small after reaching the Great Perfection in the late stage of foundation building, so that no matter how much he stimulates his potential, he cannot meet the minimum requirements for condensing the golden pill.

Of course, both of the above situations can be compensated for by the quantity or quality of the golden pill, which is one of the reasons why the golden pill is extremely important to the monk's process.

For Ren Xiaoyao, the total amount of mana in his dantian had already reached the minimum requirement for condensing the golden pill. However, Ren Xiaoyao has not entered the next stage, but is still stimulating his potential.

The quality of the Jindan of the Jiedan monks is divided into three levels, the human-level Jindan, the earth-level Jindan and the heaven-level Jindan, and each level is divided into nine grades. The golden pill between different grades and different grades will directly affect the qualifications and strength of the Jiedan monks.

Moreover, once the monk's golden pill is formed, it is difficult to improve it in the later stage, which is also the reason why the foundation building monk wants to condense a high-quality golden pill in every possible way.

In Ren Xiaoyao's heart, the Jin Dan he wanted to condense was at least at the heavenly level, or even beyond the heavenly level. It was also because of this idea that Ren Xiaoyao endured great pain to continuously stimulate the mana of his body.

When Ren Xiaoyao squeezed mana from all over his body for the eighth time, a strong feeling of exhaustion and pain had already swept through Ren Xiaoyao's whole body, Ren Xiaoyao's whole body was already sweating profusely, all muscles, organs, and tendons and veins were damaged by different processes, and the skin surface of Ren Xiaoyao's whole body was even slowly bleeding.

Ren Xiaoyao knew how to continue to forcibly stimulate the potential in his body, and he was afraid that he would collapse and die.

Of course, Ren Xiaoyao is not willing to give up just like that. At this time, Ren Xiaoyao's mind moved, took out two top-grade healing pills from the storage bag, swallowed them, and quickly refined them.

These healing pills are the best elixirs on Ren Xiaoyao's body now, and they are refined with the best elixir according to the elixir provided by the spirit of the elixir, so it can be said that most of the immortal cultivation sects can't take this kind of healing pill that Ren Xiaoyao is taking now.

As soon as the pill entered the body, the effect of the medicine quickly flowed throughout the body, repairing the damaged muscles and tissues throughout Ren Xiaoyao's body, and at the same time, Ren Xiaoyao's physical body was rejuvenated again, and Ren Xiaoyao continued to stimulate his potential for the eighth time.

It only took an hour to complete the first stage of Ren Yao's return to the sea, but the second stage of potential stimulation took three days and three nights, and most of the time was spent on the last few times of potential stimulation.

The eighth time of potential stimulation took Ren Xiaoyao four hours, and he took two healing pills before and after. However, when Ren Xiaoyao carried out the ninth potential stimulation, it took nearly sixteen hours and nearly ten healing pills.

At this time, Ren Xiaoyao, in addition to his eyes flashing with scorching light like a comet, his whole body was like skin and bones, wrinkled, and his entire body size was reduced by nearly a quarter.

All the cells in Ren Xiaoyao's body, in the healing over and over again, and the potential stimulation over and over again, are just like a person who has taken an overdose, although all of them have unlimited energy, they are also rapidly approaching the end of their lives. Through guò divine induction, Ren Xiaoyao could clearly sense that many of the cells in his body had collapsed without warning.

When Ren Xiaoyao gritted his teeth and persevered in the ninth potential stimulation, Ren Xiaoyao's body surface was already bloody, and nearly one-fifth of the muscles and tissues in Ren Xiaoyao's body had been necrotic or in shock.

"In the scriptures I have collected, in the process of cultivating the Dan, even if there are some anti-heavenly beings, there are very few that can be carried out to the ninth time of potential stimulation, at most the seventh or eighth time, and now I have carried out the ninth time of potential stimulation, which should not be bad. Ren Xiaoyao muttered to himself in his thoughts, with a slight smile on his face, revealing a satisfied expression.

Although Ren Xiaoyao really wanted to try to stimulate his potential for the tenth time, Ren Xiaoyao also knew that if he did the tenth potential stimulation, his body would collapse 100%. Moreover, even in the current state, if Ren Xiaoyao does not enter the next stage or take remedial measures in time, I am afraid that he will not survive for three hours.

As a result, as soon as Ren Xiaoyao finished the ninth potential stimulation, he immediately entered the third stage of the pill formation process, the pill absorption stage.

Ren Xiaoyao first took out three different pills that had been refined in advance to assist the knot pill and took it, and after refining, he took out the only one of the best knot pills obtained from the road of knot, and after looking at it for a few seconds, he resolutely took it.

When the potential is stimulated nine times in a row, those cells and tissues that have not collapsed are the more tenacious parts of Ren Xiaoyao's body. However, even these more tenacious cells and tissues are on the verge of collapse at this time, so these cells and tissues are in a state of extreme hunger and thirst.

At this time, when the best knot gold pill was refined in Ren Xiaoyao's body, the cells and tissues in Ren Xiaoyao's body, like a long drought and rain, frantically absorbed the effect of the best knot gold pill. Moreover, because of the effect of the auxiliary elixir, the cells and tissues in Ren Xiaoyao's body absorbed the medicinal effect of the best knot pill more and more thoroughly.

Those cells and tissues that were on the verge of collapse immediately exuded fierce vitality after absorbing the medicinal effects of the Superb Golden Pill. Ren Yao's body, which was already like skin and bones, became full in less than a pillar of incense, and his body shape quickly returned to normal.

Because of the nine consecutive potential stimulation in the second stage, Ren Xiaoyao could be sure that his physical body's absorption of the best knot golden pill would definitely greatly surpass that of other monks. Therefore, Ren Xiaoyao's physical body will be better strengthened and refined.

Of course, refining the flesh body with the best knot gold pill is only one of its functions, and its more important role is to use it to condense the gold pill.

When the best knot golden pill was refined little by little, except for a small part that was absorbed by Ren Xiaoyao's body, most of the best knot gold pill liquid turned into a torrent of rolling mana and poured into Ren Xiaoyao's dantian
