Comparatively speaking, Dutian Shenlei and Nanming are separated from the fire, but they are much milder. The former is less than seven levels, and can be compared to the natural thunder. And Nanming is away from the fire, if it can't reach the level of the Nanming glazed true fire, it can't compete with the true fire of the sun.

And Yun'er concocted this method. Another key is the separation of body and soul.

Originally, the yin soul of the monk could not be separated from the body at all if it did not reach the realm of the primordial gods, and it was often destroyed when it saw the wind.

The various winds wandering between heaven and earth, and all kinds of evil forces that wander away, will shatter the monk's soul in an instant.

Yun'er's method is to use the power of the positive and negative instruments in the 'Positive and Negative Instruments Immeasurable Heavenly Great Array' to isolate the inside and outside.

Putting the Yin in a 'bottle' and not in contact with the outside world. The separation of body and soul makes any fluctuation within Zhuang Wudao's soul thoughts not be fed back to the physical body. It will not cause the evil power in the body to fight back because of improper thoughts.

It's just that this process is extremely dangerous. In the process of cultivation, once disturbed, it may cause the power of the positive and negative to get out of control, and the yin soul will collapse under the impact of the evil force of the wind.

Fortunately, there is also a sword spirit, which can cover 3,000 zhang and can be warned at any time. At a critical time, he can control Zhuang Wudao's body, temporarily suspend this technique, and recall Zhuang Wudao's ghost.

If it weren't for that, Zhuang Wudao would never dare to use this demon refining method in this nameless mountain.

This method sounds simple, but when Zhuang Wudao began to perform it, he found that the whole process was extremely difficult.

Every step requires careful care and full attention. Even the slightest mistake can lead to unforeseen consequences.

Especially the body of the yin soul, manipulating the yin and yang of the two instruments, is extremely difficult. In the past, his skillful Dao Seal Spirit Determination was changed to Yin Spirit, but it was a thousand times more difficult.

The amount of divine thunder introduced into the body is also to be controlled and just right. If you have one more point, you may damage the body, and if you have one more point, you will not have enough strength.

If you want to refine the demonic evil in your body, it is far from enough to rely on the "Shangxiao Yingyuan Cave True Thunder True Method", and the first-order Heavenly God Thunder born from your own body.

Only with the help of the power of the Great Array, with a thunder power far exceeding ten times that of oneself, can one expel and refine the demonic breath and evil qi.

But that's not all. Zhuang Wudao tried his best, but he was still able to do it. The most painful thing was after he started refining demons.

A trace of the heavenly god thunder kept stirring in the body, and the flames burned the body, like sitting on a stove.

At this time, Zhuang Wudao has separated his body and soul. His own thoughts cannot affect his physical body, but this extreme pain can be faithfully conveyed into his consciousness and thoughts.

The whole person is like being in a legendary hell, and the pain is endless.

Only then did Zhuang Wudao realize that Yun'er said that this method of refining demons was analogous to the pain when he cultivated the first decision of Heaven and Earth Yin and Yang Great Compassion, and it was really not an exaggeration. Far from exaggerating, it is slightly conservative.

And Zhuang Wudao not only suffered this severe pain, but also needed to be distracted to control the power of the positive and negative instruments, suppressing the strength of the Dutian God Thunder and Nanming Lihuo.

At this moment, Zhuang Wudao's mind was almost shattered. It was like countless great axes, cutting his ghost into countless pieces.

That feeling of confusion and confusion, it took Zhuang Wudao a long time to barely sort it out.

"Sword Master, if you really feel unbearable, in fact, I can take you to control the positive and negative. I don't have the power to control the formation, but if it's only a part of it, I can barely do it. ”

Zhuang Wudao didn't want to think about it, so he directly refused: "You come to help me control the formation, so who will warn me for emergency and take precautions?"

In the past few years, Zhuang Wudao has almost understood the limit of Yun'er's ability.

After all, it is a sword spirit, and Yun'er's spiritual thoughts, although they can reach a wide range of three thousand zhang, are more like Zhuang Xiaohu's situation.

Although the sensing is widespread, the effect is extremely limited. For example, this 'Positive and Negative Infinite Heaven Great Array', Zhuang Wudao can control it freely with a range of three hundred zhang of divine thoughts. Changing to a sword spirit, I tried my best, but I couldn't do it.

Cultivating the Demon Dao method is a taboo. At this moment, his ghost also dies when he sees the wind. Yun'er is a fire line for him, and Zhuang Wudao can't allow him to share his efforts no matter what.

However, the sharp pain still came in waves, making his mind drowsy, and almost lost.

But at that time, Yun'er suddenly said again: "Why don't you follow me to learn another method?"

"Huh?"

Zhuang Wudao sighed softly in his thoughts, and reluctantly lifted his spirits. In his heart, he was puzzled, in his current state, where is there still time, distracted?

This Yun'er, could it be that he is crazy?

"To thoroughly cleanse the demons, it is not enough to just have the physical body, and there are also demons in the sword master's divine thoughts. ”

Yun'er explained: "My method is not so much a secret technique as a trick. It's just the right time. ”

Zhuang Wudao endured the pain of being Ling Chi, and said lightly: "Let's hear it." ”

"This technique is called 'Heavenly Mirror Soul Illumination Technique', which is also a technique of attracting the true fire of the sun and cultivating the primordial gods. However, it is slightly different from the 'Origin Hunting Demon Sutra'. It's gentler and doesn't leave any hidden dangers. ”

"Heavenly Mirror Soul Illumination Technique?Draw the Sun True Fire to Cultivate the Yuan Shen?I don't know how to go into details?"

Zhuang Wudao frowned, this method sounded like it was related to the 'mirror'. However, no matter what kind of exercises, once they are related to the true fire of the sun, none of them are simple.

Either the real supreme exercises, or self-defeating.

"This technique is to use the method of mirror reflection to gather the power of the moon and draw out a trace of the true fire of the sun and illuminate the original god. You can start with one side and gradually increase to dozens or more than 100 sides. When cultivated to the extreme, the sword master primordial god can be transformed into the soul of pure yang several realms in advance. This method was transmitted from the Alien Realm to the Celestial Immortal Realm, and I also obtained it by accident, and it is said that it was created by an earth-shattering peerless person. However, this method is only suitable for Qi realm cultivators, and none of my previous sword masters have practiced this technique. ”

"The power of Yuehua, gathering the true fire of the sun? Isn't Yuehua too yin? How can it be related to the true fire of the sun?"

Zhuang Wudao asked strangely, as for the Xenodimensional Realm that Yun'er said, he didn't care much. Outside of Tianyi, there are hundreds of millions of large and small shijies. This 'Heavenly Mirror Soul Illumination Technique' is mostly from one of them.

"The sword master's statement is also fallacious, you must know that there are no absolutes in everything in this world. There is yang in yin, and there is yin in yang. ”

Yun'er shook her head and said, "Although the moon star is among the stars of Taiyin, the real power of Taiyin does not come from the bright moon and stars, but from the endless void. On the contrary, these stars are the purest true fire of the sun. The purest power of the cold void of Taiyin is also like the true fire of the sun, from yin to cold, dangerous, and difficult to be absorbed. It is precisely after mixing the true fire of the sun that it can be absorbed by the monk demon cultivator. And the reason why the moon star is the first of the Taiyin stars is not because the power of the Taiyin contained in the moon is the most prosperous, but only because of the true fire of the moon star and the sun, and the power of the Taiyin after neutralization, it is only suitable for monks and demons to practice. ”

"Is that so?"

Zhuang Wudao only knew the power of Yuehua, which was one of the power of Taiyin, but it was more gentle. The vast majority of Yin demon cultivators started by absorbing Yuehua.

But they didn't know that the moonlight and the star power of the heavens contained the true fire of the sun.

"It's just that now is the right time? I can't even bear these Heavenly God Thunder and Nanming Separation Fire in my body now. ”

It's really impatient, he won't hide it, this is beyond the limit of his perseverance. Refining the soul with the true fire of the sun is tantamount to seeking death.

"No, this 'Heavenly Mirror Soul Illumination Technique', the fourth sword master has made some improvements. After all, it is a method of the alien realm, and it may not be suitable for the heavenly immortal realm. It's just that this method has not yet been verified. However, the fourth sword master, who has cultivated to the sky, has far surpassed the level of the immortal king, and after her improvement, there will definitely be no mistakes or omissions. ”

Just as he spoke, a mantra had suddenly appeared in Zhuang Wudao's mind. However, it was Yun'er who spent his spiritual energy and directly imprinted the cultivation method of this 'Heavenly Mirror Soul Illumination Technique' into his divine thoughts.

At the same time, Zhuang Wudao's body manipulated by Yun'er also moved. The three 'Sancai Xuanyang Sword' flew out of the sword box at the same time, and a special rune flashed on the sword body. Then they each escaped to the window lattice, replaced the mirror with a sword, gathered and reflected the moonlight sprinkled outside, and turned to shine on Zhuang Wudao's ghost.

Zhuang Wudao raised his eyebrows, and sure enough, he could feel the trace of the true fire of the sun contained in this moon.

It's just that at this moment, instead of feeling scorching, he felt a wave of cold and cool feeling, spreading to all corners of the Yuan Soul.

"Huh!"

Zhuang Wudao was extremely surprised in his heart, with the three 'Three Talents Xuanyang Sword' shining the sun true fire one after another, he actually felt a lot more relaxed. The burning flame and thunder power in the body is no longer so painful.

Especially after he began to urge the cultivation method of the 'Heavenly Mirror Soul Illumination Technique' in the Yuan Shen.

The slightest distraction was completely eliminated. The whole person is like soaking in a cold pool, with detached thoughts and not stuck in things. The pain in the body is still there, as if it is separated by a membrane, and it feels like a dream, not real.

And gradually, Zhuang Wudao no longer paid attention to it, meditated on it, and completely forgot about it and me.
