While Yun Yifei was standing, while the three of them were checking his physical condition, Yun Bohai used his spiritual power, his palm opened, and a water ball rotated and condensed in his palm, and after a while, a trace of heat came out.

Although Yun Bohai has a mutated wind spirit root, all spells and magical powers are naturally related to wind attributes, but the spiritual power in his body can also simulate spells with other attributes after operation and transformation, but it consumes a large amount of spiritual power, but like this kind of primary small spell that simply condenses the water ball, for Yun Bohai in the Dan period, the spiritual power consumed is naturally not worth mentioning.

With a slight wave of his arm, the water balloon came out and landed directly on Yun Yifei's palm, and while turning, it went up along his arm, burrowed into his clothes, and then traveled all over his body.

Yun Yifei only felt that the water balloon was unusually warm, and it was very comfortable to walk around him, and after a while, the water balloon drilled out of his other cuff, and he could see it clearly, the transparent water balloon had become pitch black, naturally because it had cleaned up the dirt on his body.

Seeing that Yun Yifei's physical condition was good, his meridians naturally improved, and there was no period of weakness that should occur after taking the pill, the three of them decided to continue to let him take the Huoluo Pill.

Due to the nourishment of the Activating Pill and the effect of absorbing the aura, it was already able to be consumed by the body, so without a drop of water for two days, Yun Yifei did not feel hungry, and he did not even feel that it had been so long.

Sitting cross-legged, Yun Yifei opened his mouth to swallow the pill again, and the familiar feeling appeared again, fortunately, he had the first experience, and he could be regarded as having a psychological preparation, and that uncomfortable feeling hit again, after all, he realized the benefits of the pill to the body, so now he gritted his teeth and persevered, waiting for the transformation of the body by the medicinal power.

While Yun Yifei insisted, Yun Bohai and the three of them paid attention to the changes inside his body, the meridians were pliable and strong under the nourishment of the medicinal power, and slowly expanded from the inside to the outside, although it was a slight, but it proved that this method was effective, and the three of them saw hope in it.

And when the medicinal power reaches the meridians blocked by the purple mist, the purple mist absorbs it frantically again, but fortunately, the medicinal power is sufficient, and the excess medicinal power still acts on the meridians, and the meridians blocked by the purple mist are also absorbed to the maximum extent like a hungry man at this time.

After a long period of observation, after the wisps of purple mist absorbed enough spiritual power, it would flow up with the spiritual power in its body, until it ran into the dantian, except for a small part of the purple mist and the assimilation of spiritual power, most of the purple mist was separated from the spiritual power, as if it was alive, rushed to the purple beads floating in the dantian, and slowly integrated into it.

The three of them also shook their heads secretly in their eyes, helpless, when Yun Bohai wanted to use his own spiritual power to enter Yun Yifei's meridians, the purple mist frantically resisted the external spiritual power like repulsion, and at this time, a small part of the purple mist was integrated into the purple bead, obviously there was consciousness in the purple bead.

After two days and two nights of suffering, the reaction of the medicinal power completely subsided, Yun Yifei stood up and moved, there were still slimy impurities sticking to his body, the color was slightly lighter than yesterday, and it was a little less, but it still smelled bad.

Yun Yifei cleaned up the impurities on his body, changed his clothes, and after eating, he played in the Dan Dao Sect for half a day before returning to the cave mansion in Guanli Mountain.

Normally, after taking Huoluo Dan, the body will have a weak stage, due to the effect of the medicinal power, the meridians, blood vessels, and muscles will be sore, this soreness will slowly recover after the medicinal power disappears, and it will take at least a day or two to recover completely if the physical condition is good, but Yun Yifei does not have this situation, and the body is also nourished by spiritual power, which is better than before.

At this time, Yun Yifei sat on the futon in the stone room again, his eyes were closed, his brows were furrowed, his face was extremely resolute due to his teeth clenched, although it was the third time he took the pill, but the pain from inside the body was still extremely clear, there was no other way but to persevere, and then persevere.

After the night, there is dawn.

In this way, after taking six Huoluo pills in a row, the impurities that came out of the body became less and less, and the time to absorb the medicinal power became shorter and shorter, from the first two days and two nights to the time when taking the sixth pill, it took one day and one night, and the absorption speed of the body and the purple mist became faster and faster.

Yun Yifei's body changed, the three of them saw it clearly, the expansion of its meridians, coupled with the purple mist in the meridians was either assimilated with spiritual power, or integrated into the purple beads with the flow of spiritual power, now the meridians are much cleaner, but they are not completely unblocked, there is still purple mist in several meridians that were completely blocked before, but the color is darker than before, and the purple mist at the meridians that is not completely blocked also seems a little thinner, it can be seen that the darker the purple fog, the richer and more tenacious.

Due to the expansion of the meridians a little, there are already gaps in every meridian that was completely blocked before, and the spiritual power can be regarded as being able to pass through, according to the reason, it can be cultivated in this way, but the meridians are narrow in some places, but they can be regarded as passable.

After the three of them discussed, they decided to let Yun Yifei run his spiritual power to try, Yun Bohai put a jade slip on the stone table, which was naturally an exercise that had been prepared for a long time, Guan Lishan was curious, and his divine sense probed and looked at it.

"This exercise is simply perfect for Fei'er, where did you get it from? After a while, Guan Lishan's divine sense retreated, and Zhengse said.

Zhao Wenqi picked up the jade slip out of curiosity, and his divine sense probed in, only to see that the beginning was marked with the words "Pure Heart Formula", and he knew that Yun Bohai's Qi Refining Period Exercise was this Pure Heart Formula, but when he looked down at the content, he was also slightly surprised in his heart.

Pure Heart Formula, is a superior Qi refining period cultivation exercises, but also Yun Bohai's introductory exercises, and when he came to the Dan Dao Sect, there was a small episode in the Fang City of Yunlan Villa, a monk in the early stage of the Dan Dynasty bought the formation, due to the lack of more than 100 spirit stones, with two exercises, one of the jade slips recorded in the exercise name called "meridian theory".

The flow of spiritual power is naturally inseparable from the bearing of the meridians, and its exercises are mainly through the special operation of spiritual power to achieve the exercise of the meridians, so that the meridians can withstand more spiritual power circulation.

Yun Bohai with his experience in cultivating to the Dan period, the two exercises into one, take their essence, remove their dross, most of the cultivation exercises in the Qi refining period are able to check the spirit and guide the qi to improve the cultivation, and in the foundation building period can be regarded as really stepping into the ranks of cultivation, at that time to find a set of practical exercises, but the pure heart recipe in the improvement of cultivation at the same time, but also can have the effect of pure heart and calm, clear and calm, for the future cultivation is also good, it can be regarded as laying a good foundation in advance.

Summoned Yun Yifei and explained the exercises in detail, starting from the simplest how to control spiritual power, how to go along the meridians, and then returning to the dantian after a week of operation, the effect of each meridian on the corresponding viscera, the speed at which the spiritual power should be controlled, how to control the speed if it is too fast, how to deal with it if it is too slow, and some matters that should be paid attention to, the explanation is comprehensive, and finally the first layer of the exercises of the pure heart recipe are explained in detail.

Yun Yifei sat down cross-legged, his arms drooped freely, placed on his knees, and slowly exhaled, his mind was calm and calm, and after feeling the weak spiritual power of the dantian, according to his father's explanation, he urged the spiritual power to run along the meridians.

Yun Yifei felt that the spiritual power seemed to be alive, and when he felt it, the spiritual power also seemed to give feedback, and when the spiritual power was running through the meridians, he felt that the spiritual power was himself more than once.

The spiritual power is fused with the spiritual energy absorbed through the body through the collection of meridians, but the spiritual energy has been transformed into a little bit of spiritual power.

Once the spiritual power is activated, the body is also like having a suction force, and the surrounding rich spiritual energy is absorbed by it.

Spiritual power nourishes the meridians that flow through it, and nourishes flesh and blood through the meridians.

Yun Yifei was not in a hurry, controlling the speed of spiritual power, but suddenly felt that something was blocking the way, and instantly felt depressed, and even felt that it was a little difficult to breathe, and his mood gradually became irritable, so he controlled the spiritual power to impact forward vigorously.

"Don't be in a hurry, be calm, calm down, control your spiritual power, stretch and stretch it, and look for gaps to pass through. At this moment, the voice of his father Yun Bohai came into his mind.

Yun Yifei then stabilized his mind, took a deep breath, and slowly exhaled it, and suddenly felt a lot more relaxed in his heart, controlling the spiritual power to slowly lengthen, and flowing forward again, trying several directions in a row, but to no avail.

"Stretch the spiritual power a little longer. His father, Yun Bohai's voice, came again.

Yun Yifei manipulated the spiritual power to stretch again, like a long thin line, and just when he felt the limit, his father's voice came at the right time: "It's okay, find a breakthrough, now it's up to you." ”
