Yu Lie returned to his room, and he arranged the girl outside the door, on the one hand, to prevent the other party from peeping into his secrets, and on the other hand, putting a person outside the door can also play a role in letting the wind out.

In the room, a huge Dan furnace has been placed steadily.

Yu Lie wandered around the corner of the room, putting up warning charms one after another. He arranged it extremely carefully, even the roof and floor, which was more important than when he was alchemizing before.

After all, if the alchemy fails, at most it will be a furnace and destroy the Dan furnace, and if something goes wrong in the transformation, it will make people regret it for the rest of their lives.

After the arrangement was done, Yu Lie took out another charm, carefully drew a figure on the floor of the room with spirit stone scraps, and then pasted the charm in the center.

Buzzing!

As soon as the rune paper fell, a flash of spiritual light flashed in the room, and immediately a trace of spiritual energy was released from the ground, which filled the room, making the rest of the spirit lifted.

He was overjoyed, but his face was also painful and muttered: "This spirit gathering talisman is a little expensive, but the effect is not bad, it seems that it can really be worth half of the concentration of spiritual energy in the cage house meditation room." ”

This spell is the spirit gathering charm that Yu Lie specially purchased for his own transformation in the wild, although it is a one-time and only half of the effect of the spirit gathering circle, but it can be used improvised, which is definitely better than nothing.

Next, Yu Lie sat cross-legged in the room, quietly waiting for the aura concentration in the room to reach its peak, and silently reconciled the true qi in his body.

At the same time, he also felt the fire yuan qi remaining in his body.

Thanks to the mad dragon flame and the action of the ghost and god surnamed Nadu, the qi of the fire yuan has been filled in the spirit platform of the remaining columns, and after a day has passed, there is no sign of decay.

In this way, when Yu Lie broke through, he would directly avoid the process of carefully ingesting the Fire Yuan Qi, and he only needed to guide the remaining Fire Yuan Qi into the physical body and mix it into the True Qi.

And this point is not easy for the rest of the current fire law master, but it is not a difficult thing, at most it is a little troublesome.

Thinking about it, Yu Lie suddenly had a kind of realization in his heart.

He said secretly: "No wonder in the Golden Stone Poisonous Fire Breathing Method, the Poisonous Flame Spell is specially marked as the first choice!"

The key to the change of water and fire lies in mastering the nature of water and fire, and cultivating a fire method is undoubtedly able to comprehend the mystery of fire in advance through the cultivation of spells, and when it breaks through, it can improve the success rate.

Yu Lie judged again: "If my guess is correct, if a Taoist disciple can master both the fire method and the water method before the change of water and fire, and both spells are mastered, then when he completes the change of water and fire, the difficulty of him should drop sharply. ”

Indeed, as Yu Lie guessed, if there are Taoists who can do this, then when they break through the barrier of fire and water, the success rate should be more than eighty percent, and even the need to take medicine is very rare.

With a little bit of snack, it's easy for such characters to get through the changes of fire and water.

It's just that if you want both methods to be masterful, and they are fire and water methods that conflict with each other, they require extremely high talent from Taoists, and basically no Taoists can achieve them in advance.

As for those who rely on the number of years and want to use decades of hard work to refine the two spells to the fullest, as they get older, their physical vitality will also decline.

At that time, even if it has the effect of spell blessing, it is still unknown whether the success rate will be high or low when breaking through.

A reverie appeared in Yu Lie's mind, making him faintly realize: "Today's Immortal Dao, the cultivation technique has become an important factor in the growth of Dao practice. One fire spell can help me transform, and maybe other spells can do the same...... It seems that when choosing a spell in the future, you should not only consider the power, but also consider the impact on the bottleneck of the realm. ”

After thinking about it for a while, he suppressed the distractions in his heart.

At this time, the aura in the room had already climbed to a good level of intensity, and no matter how high it was, it was not something that the Spirit Gathering Charm could do.

Yu Lie's gaze suddenly became hot, he got up, slapped the Dan furnace with his hand, shook the lid open, and jumped into the Dan furnace by himself.

A piece of Earth Fire Essence Crystal had been placed by him in the lower layer of the Dan Furnace in advance, and the Earth Fire Flame could be born at any time.

Buzzing!

The Dan furnace vibrates, and the aura gathers.

I saw Yu Lie sitting naked in the Dan furnace, and drank in a low voice: "Ignite the fire!" ”

Burst! As soon as his words fell, a flame rose from the bottom of the Dan furnace, and burned to the upper part of the Dan furnace in one breath, only a few inches away from the rest of the body.

Such a fierce and close-range earth fire, if it is replaced by an ordinary Taoist, even if the other party is also a master of fire and knows how to resist fire, it does not mean that their physical body can withstand it.

And Yu Lie had experienced the Earth Fire Refining Body beforehand, and such close contact with the Earth Fire only made him feel the scorching heat.

And it was this scorching heat that triggered the fire element qi in Yu Lie's body.

Wisps of originally calm vitality descended violently from the spiritual platform above his head, and rushed into his dantian limbs, making Yu Lie's mouth can't help but make a creaking sound.

This is the fire on the outside, the fire on the inside, and the addition of the inside and outside, so that the internal organs of the rest of the column seem to be placed in the oven. For a while, the pain struck, and he couldn't help but clench his teeth, and his teeth creaked.

This situation reminded Yu Lie of the scene when he completed the transformation of copper and iron bones in the past.

When he was still just needing to peel off the skin, but now with the blessing of Huo Yuan's qi, it was as if he had broken open his abdomen and stuffed it into the coals of fire, and the pain was even worse.

In fact, it doesn't have to be like this to use the fire element qi to transform the body, and the rest of the column can also use the time to polish it vigorously, and slowly guide the fire element qi to all positions of the body.

It can be as little as seven days, as much as a month, and it will naturally be successful.

But it's a pity that Yu Lie is not in Dao City now, but in the foreign world, and he doesn't have so much time to proceed slowly. Otherwise, once there is a change in the assessment outside the house, and he is still breaking through, it will be bad.

Especially in addition to refining the Qi of the Fire Yuan, he also had to refine the water-avoiding pill and carry out some water-type transformation. The latter is not very familiar to him, and it is estimated that it will take more time than the former.

In the Dan furnace, Yu Lie's face was red, and the green tendons on his forehead burst out, which was quite hideous.

Fortunately, after surviving the initial pain, the fire yuan qi in his body flowed evenly in the five internal organs along the meridians, which not only brought pain, but also brought great vitality and vitality.

The fragile viscera, in this kind of vitality, is constantly reborn and tenacious, evolving in an extraordinary direction.

For a day and a night, Yu Lie didn't drink a mouthful of spiritual liquid, nor did he swallow a single pill, he relied on his own accumulation, meticulously controlled the qi of the fire element, tried his best to forge his body, and cooked himself as an elixir.

His preparation and mental effort were not in vain, and as a day and a night passed, Yu Lie's body glowed red, and his complexion became serene, completely adapting to the transformation.

At the same time, his internal organs and six internal organs have gradually reached the point where he can drink copper juice magma in the process of passing through, far exceeding the level of swallowing gold and serving jade.

After patiently polishing for a long time, after confirming that there was nothing abnormal in his body, Yu Lie opened his eyes and pondered that it was time to take out the spirit of the spirit crocodile and cook it.

But before he got up, he looked down and pondered, and a thought popped into his mind:

"Why do you need to completely separate fire and water?

Now that the transformation of fire qi has reached the end, and there is still fire yuan qi in my body that has not been consumed, why not directly put the medicinal herbs into my body, and use my physical body as a pill furnace to cook in my body? ”

The thought jumped out of his mind, and Yu Lie's eyes jumped to try.

He sat cross-legged in the Dan furnace, stretched out his hand, and the delicate wooden box placed next to him flew in and fell into his hand.

Gently opened, a ball of spiritual light, and a box of jasper-colored essence blood appeared in Yu Lie's eyes, he sniffed lightly, his mouth and nose were filled with not a fishy smell, but a refreshing fragrance, which lifted his spirits.

Yu Lie sighed lightly: "It's really a good medicinal herb!" ”

There was a look of hesitation in his eyes, and after thinking about it, he still didn't put the spirit crocodile essence blood and soul directly into his mouth, but took the bronze wine glass.

Yu Lie put this essence blood and soul into the wine glass, rinsed it, checked it a few times, and found that there was nothing unusual, and whether it was essence blood or soul, it was all concentrated and purified.

At this time, he took a few drops of the spirit crocodile's essence blood, and also ingested a few traces of his soul, took it into his mouth, and used the liquid on the tip of his tongue as a mixture, and the fire yuan qi in his body was mixed with true qi as firepower, and began to refine.

Whew!

The fire outside the Dan furnace was still burning, and the two spirits in the remaining rows were like bellows, whirring and agitating, and there was a faint roar like wind and thunder.

】

After ten breaths and one percussion, after a full ninety-nine and eighty-one percussions, Yu Lie swallowed the spirit crocodile medicinal herb in his mouth and incorporated it into his abdomen for further refining.

It's been another quarter of an hour.

Yu Lie in the Dan furnace opened his eyes, and his eyes showed joy:

"Feasible! I take the body as the furnace, the true qi as the flame, and the will as the wind, so I take the essence and blood soul of the spirit crocodile, and the internal alchemy of the elixir, which can be described as twice the result with half the effort! ”

The experiment was successful, Yu Lie no longer hesitated, he took the medicinal materials in the wooden box again, and poured them into his mouth.

According to the ghost surnamed Du, if this box of spirit crocodile essence is refined properly, in addition to being able to obtain the qi of the water element from it, it is also possible to obtain the "power of a crocodile".

Yu Lie wants to do this, so he has to refine it in one breath as much as possible!

A whole medicinal herb entrance, his mouth was full, and the breath of the medicinal herbs rushed straight to his heavenly spirit cover, in addition to the fragrance, the kind of fishy smell that existed in the essence and blood, no matter how subtle, it was inevitable to enter his perception.

Fortunately, it is so difficult, compared to the burning feeling of the five organs just now, it can be regarded as pediatrics.

Yu Lie endured, reconciled them one by one, slid his throat, and incorporated the essence and blood essence of the spirit crocodile into his body, and used his true qi and fire yuan qi to start refining.

At this time, an accident occurred.

The huge water attribute medicinal power came into contact with the fire element qi in Yu Lie's body, and the water and fire were excited, causing a tremble.

Roar!

A faint vibration like thunder appeared in Yu Lie's body, causing the Dan furnace to tremble slightly.

Yu Lie sensed this, his heart tensed, and he was about to spit out the medicinal herbs in his body at any time.

But he calmly looked at it, and found that with this trembling, his flesh was trembling, and the fire yuan qi and the water yuan qi were intertwined, which was more mysterious than when he collected the qi alone just now, making his muscles, bones, skin and flesh all over his body become stronger.

Continuing to endure it, a tingling sensation spread to the rest of the body.

A feeling of great joy appeared in Yu Lie's heart:

"The blend of fire and water, this is the transformation has reached the final stage, and it is about to be completed!"

He could clearly perceive that in addition to his physical body, his true qi was also in the process of transformation, from the previous burst to a combination of rigidity and softness, and the texture was continuously improving.

But what also puzzled Yu Lie was that according to the Taoist book and the cultivation notes of his sister-in-law, such a stage of water and fire blending and mutual aid often did not last too long.

And now his situation is that the medicinal herbs in his abdomen are just on the right track, and they are gradually being sucked by him, and the duration of this stage will definitely not be short, to say the least, it will be three days and three nights.

So Yu Lie was taking the medicinal herbs while paying attention to it.

Soon, he confirmed that the longer the "blend of fire and water" lasted, the more beneficial it would bring him, and the more beneficial it would be.

At this moment, Yu Lie was completely relieved, and he was immersed in the process of transformation.

One, two, three.

Sure enough, as Yu Lie expected, his "Water and Fire Fusion" stage lasted for three days and three nights, and even if the Fire Yuan Qi in his body was more sufficient, or at the beginning of the transformation, he would have carried out the fire transformation and water transformation at the same time, and the maintenance time would be even longer!

But three days and three nights are already enough.

When Yu Lie in the Dan furnace opened his eyes again, his gaze was simple, his expression was restrained, and his complexion had returned to a state as white as jade, neither too pale, nor red-hot and glowing, and there was nothing unusual.

But at this moment, the earth fire outside the Dan furnace was still burning fiercely.

Even if it was separated by the Dan furnace, the rest of the column fell in it as if nothing happened, and not even a single hair was scorched, which was still very wrong.

A burst of laughter rang out in the room.

I saw Yu Lie with a smile on his face, got up from the Danlu Huo Ran, and said with a long chant:

"My water and fire have been transformed, and they have been successful!"

Delighted, his eyes showed a breath-taking essence, and a pure spiritual light also rose from the top of his head.

The height of the spiritual light is not one zhang high, but it has reached more than one zhang and one foot, which is converted into a Taoist line, which is as much as eleven years!

With this breakthrough, Yu Lie not only successfully transformed his physical body and condensed his true qi, but he also relied on drugs to increase his cultivation after the breakthrough, saving a whole year of hard work!

Yu Lie was overjoyed, with emotion on his face, he stretched out his hand and slapped it fiercely on the Dan furnace:

"It's not in vain that I've prepared so much!"

Bang buzz.

The Dan furnace in the room sounded loudly, echoing in bursts, which should be in someone's excited mood.
