How to refine the Heavenly Demon Confusion Pill made Chen Feng very worried, after all, the Heavenly Demon Confusion Pill was not an ordinary pill, it was related to Chen Feng's great cause of cultivating immortals, once it was refined by Chen Feng himself, Chen Feng himself did not dare to imagine the consequences. With apprehension, Chen Feng breathed a long sigh of relief after reading the jade jian, his worries were redundant! Even the questions he could think of, could Nie Hailong, who was the Elder Ancestor of the Jiedan, not think of it? Otherwise, with his ability as the Ancestor of the Immortal, even in that kind of situation where the mountains and rivers were exhausted, it would not be very difficult to get a few Zhuji Dan.

"The Law of Life and Refining!"

Chen Feng was in a trance, he had a deep understanding of Fu Li, but he didn't know anything about alchemy, and he was surprised by the laws of birth refining adopted by the Heavenly Demon Confusing Heart Pill, more precisely, it was unheard of. The alchemy he knew was only a traditional Dan furnace refining, and he didn't know anything about this strange method of refining and refining.

The jade slip left by Nie Hailong recorded that the attributes of the Heavenly Demon Confusion Heart Pill were too domineering, if the power of the entire Inner Dan and Spirit Grass was concentrated in the Dan Pill, not to mention a monk who refined qi and attained great perfection, even a monk who built the peak of the foundation would also be supported by the abundant spiritual energy! The method of life refining is to solve this problem and research, the whole process of refining it is also the process of the monk taking the pill, while extracting the spiritual essence of the inner pill and the spirit grass through specific means while integrating it into the body of the monk of the pill, the cycle is gradual, so that the possibility of taking such a high-level pill for the monk of the Great Perfection of Qi Refining will be given, but this practice has extremely serious drawbacks. During the refining process, the whole process of the monk receiving the medicinal power is like being cramped and stripped of the marrow by someone, and he needs to endure inhuman torture, and at the same time, the whole process cannot be stopped, otherwise the previous efforts will be wasted, and it is better to say that the loss of control of the Inner Dan is the end of the destruction of the Dan and the death of the person. In addition, this kind of refining will cause the energy of the entire inner pill to escape to the outside world to reach as many as nine layers, and the power that really enters the monk's body is less than one layer, and the utilization rate is extremely low.

"Less than one layer of power ......!"

Even Chen Feng himself couldn't help but twitch the corners of his eyes when he saw such a record! There was too much spiritual energy wasted! No wonder the Heavenly Demon Confusion Pill was gradually eliminated after the ancient times. However, Chen Feng can't control so much now, as long as he can successfully build a foundation, not to mention one Neidan, even ten Chen Feng thinks it is valuable!

After flying for half a month, Chen Feng completely moved away from the area under the jurisdiction of the Ancient Spirit Sect and came to a barren mountain range. This place is a place that he is more satisfied with after many investigations, and there are no monsters and monks, the geographical location is very remote, it is a rare "Feng Shui treasure land", but it is a pity that the aura here is extremely thin, so thin that it is almost impossible to perceive. Everything is not perfect, Chen Feng's demand for aura is not too high, so he endures it.

There has always been a saying in the immortal cultivation world that building a foundation realm is the first step in transforming into an ordinary person, and the qi refining realm is just a reserve. Building the foundation, knotting the Dan, Yuan Ying, and the god who doesn't know whether it exists, the four realms of the human world, step by step, only by cultivating to the realm of foundation building, can you really have a trace of hope for longevity.

Because he needed to prepare a good Danding temporarily, Chen Feng didn't have many spirit stones on his body, so he had to make talismans again to earn spirit stones, but fortunately, there were still a lot of blank rune papers on his body, but he didn't worry about raw materials. For this reason, Chen Feng spent half a year making talismans, and got a large number of low-level talismans and a part of the middle-level talismans, not only that, but Chen Feng's divine thoughts were also able to grow again, at night Chen Feng used the demon beast Neidan to temper, and the talisman was stable during the day, so it was normal for the high-intensity compression of divine thoughts to grow, but in this way, Chen Feng was tired, and almost fell asleep in this cave for ten days before his spirit gradually recovered.

With a large number of talismans obtained, Chen Feng concealed his identity and went to Lianyunfang City to trade the treasure of a large refining shop, Shuixin Ding! Shuixin Ding is of excellent quality, the internal force is mild during alchemy, and it has a considerable alchemy rate bonus, Chen Feng is happy for ten minutes. Of course, such a large number of middle-level talismans inevitably caused an uproar in Lianyunfang City, coaxing a talisman master to settle in the city, and the major shops were fighting openly and secretly and threw olive branches to him, but Chen Feng himself had already returned to the Wild Cave Mansion and began to impact his foundation building bottleneck.

Chen Feng sat calmly in the Juhua Water Heart Ding, all over his body, there were a large number of rare precious spirit grasses, Yin Zhi, shrugging blue flowers, Jingyuan grass, Tibetan flowers, etc., but the most eye-catching thing was a fist-sized inner pill floating in front of Chen Feng's eyebrows, at this time it had been completely unsealed, and the extremely rich demonic qi filled the inside of the Water Heart Ding, submerging Chen Feng and the spirit grass, and even the cave shrouded in the formation faintly appeared a faint demonic aura.

When the time was ripe, Chen Feng closed his eyes and pinched the demon fire technique with both hands, and a wisp of blue transparent flame jumped into the air out of thin air, the demon qi was the guide, and the human fire was the source to quickly ignite all the demon qi, and the blue demon fire became more and more blazing, and everything in the ding could not escape the demon fire, and Chen Feng was not spared.

The blue demon fire is transformed by the essence of the inner pill, and the internal temperature is extremely high, not under the general earth fire quality, this fire is not extinguished, and the alchemy is not stopped.

Whenever Chen Feng's body cracked under the scorching demon fire, a part of the surrounding spirit grass essence would turn into clear qi and pour into Chen Feng's body to maintain balance and ensure that Chen Feng's body would not be destroyed. The physical body is unhindered, but the divine mind has endured inhuman suffering, the poisonous fire attacks the heart, the body is torn and repaired, and all these kinds of trials add up to Chen Feng's tenacious will almost collapse, if it weren't for the fact that there is a trace of clarity in the depths of his heart, Chen Feng would have failed from the beginning!

The calcination lasted for two whole days, and Chen Feng's body ushered in a great change, even if the demon fire burned all over his body, he could barely bear it, and at the same time, the spiritual power in the demon beast inner pill was further released and fused with Chen Feng's body, making Chen Feng's body more tough and strong, as hard as silver iron, out of the realm of mortal bodies.

The biggest change is the mana in Chen Feng's body, every trace of Inner Dan essence is integrated into Chen Feng's body, Chen Feng's mana will be forcibly condensed once, Chen Feng has taken a large amount of heavenly materials and earth treasures before, and even got a wisp of the mana cultivated by the ancestor of the Jie Dan, his own mana is extremely pure, this time the inner Dan essence has been forcibly condensed to an amazing semi-liquid state again through a special method, and the mana strength has also exceeded the scope of the Qi refining period, when Chen Feng's mana is completely liquefied, Chen Feng has a strong mana that is truly comparable to the foundation building period!

Five days have passed, more than nine layers of mana in the whole body have been liquefied, only a little mana is not perfect, under the continuous catalysis of the blue demon fire, that bit of mana seems extremely stubborn, and it can never be condensed and liquefied, not only that, but Chen Feng actually felt a bottleneck in his body to prevent his mana from liquefiing, and let Chen Feng impact in every way, this bottleneck did not move.

Since he couldn't break through on his own, Chen Feng bit his teeth, and his spasmodic palm struggled to pinch out a magic seal, and the demon qi sprayed at the demon pill instantly increased greatly, the blue demon fire burned even more vigorously, and the effect of the demon pill spirit grass poured into Chen Feng's body in large quantities, and at the same time, a large amount of demon qi condensed and formed the demon tiger law phase slammed into Chen Feng's body from the ding!

"Poof!"

The moment the Demon Tiger Law collided into Chen Feng's body, the solid bottleneck shattered, and the mana of less than one layer immediately began to liquefy, and all the mana in Chen Feng's body was liquefied in just one hour! An unprecedentedly powerful feeling arose, and at this moment, Chen Feng's mana level had reached the foundation level!

Chen Feng clenched his fists, carefully feeling the surging mana in his body, even if he was now suffering the pain of demonic fire attacking his heart, he couldn't help but smile, he had waited too long for this moment! Whether it was the path of cultivation in the future, or the deep feud of the sea of blood, it needed strong strength support, what Chen Feng had been worrying about didn't happen after all!

However, Chen Feng soon noticed the mutation! The mana in Chen Feng's body had been completely stabilized and condensed, but the spiritual power of the demon pill had not yet been exhausted, and it was still pouring into Chen Feng's body through the demon fire! No matter how Chen Feng urged the magic trick in his hand, he couldn't stop at all, he could only let the spiritual power pour into his body, and his mana would be impacted in all directions, what made Chen Feng even more frightened was that the mana in the demon pill was too huge, and his current state couldn't bear it at all! Chen Feng's skin had already begun to crack, revealing terrifying blood marks! Before Chen Feng could find an effective way to slow down the expansion of mana, he suddenly fell into a coma!!

There are three steps to break through the foundation building, which are law, demons, and life, also known as the three forms of enlightenment. Previously, Chen Feng had crossed the stage of mana liquefaction and condensation with the help of the power of the demon pill, and the mana had reached the level of foundation building, but the spiritual power contained in the demon pill was too huge, Chen Feng could not fully use it at all, but was forcibly infused into the body by the demon pill and could not control it, and what was even more desperate was that at this time, Chen Feng was completely unconscious because of the catastrophe of the heart demon!

Although Chen Feng's divine thoughts have fallen silent, the demon pill spiritual power has not stopped and is still infused into Chen Feng's body, Chen Feng's body is further expanded under the impact of huge mana, and the previous blood marks have also expanded to several feet, Chen Feng is now like a porcelain doll that is about to be broken in the next moment

It may explode, but the spirit grass of the Heavenly Demon Confusing Heart Pill is extremely extraordinary, there are as many as several plants at the foundation level, even after so many days of Chen Feng's consumption, they are still not exhausted, at this time they have become Chen Feng's life-saving straw! These spirit grasses dispersed into Chen Feng's body through the blue demon fire, repairing Chen Feng's shattered body and hanging Chen Feng's life.

This state did not last long, and changes occurred. The hideous blood marks on Chen Feng's body slowly all transferred to Chen Feng's back, forming a strange pattern! Then the spiritual power in the demon pill poured into Chen Feng's back as if it had found an outlet, this strange pattern became clearer after getting these mana, Chen Feng's body lost these excess mana and gradually calmed down, lying naked in the ding, those demon fires burned on Chen Feng's body without leaving the slightest trace, but was gradually absorbed by Chen Feng!
