Spirit Fire Refiner? Fire Evil Container!

Yunxiao had already made arrangements for this. He first absorbed the true demonic energy to practice and strive to improve his cultivation level.

After reaching the stage of transformation, the worst that could happen is to change the cultivation method.

Even if he could not change the cultivation method, as long as he sneaked into the spirit world, there would always be a way to get rid of the demonic energy and return to spiritual cultivation.

Ruyin still didn't like it, fearing that she would become a real demon cultivator in the end and could never turn back.

In order to reassure her, Yunxiao directly absorbed the true demonic energy and practiced the Qingyang True Demonic Art and the Guishui True Demonic Art.

As expected, with the blessing of extremely pure true demonic energy, Yunxiao's cultivation speed has greatly improved.

According to preliminary calculations, Yunxiao's cultivation speed has increased by more than seven or eight times by refining the true demonic energy and the demonic essence.

The reason why the cultivation speed is so fast is of course that Yunxiao refines the pure true demonic energy and the demonic essence, which is extremely suitable for the cultivation of the original ancient demonic art.

The second is that the biggest danger of absorbing true demonic energy is to impact the soul and cause mental disorder.

Yunxiao, who had practiced the Nine-Transformation Soul Technique, had a strong soul and was protected by the Soul Shield and the Soul-Solidifying Shield.

After resolving his mental disorder, the advantage of the ancient magic technique in terms of cultivation speed was fully demonstrated.

Of course, the cultivation level of the Transformation Soul accumulated by absorbing spiritual energy in the previous sixty or seventy years was reset to zero overnight.

Yunxiao's cultivation level also completely returned to the time when he just advanced to the Transformation Soul.

Ruyin saw Yunxiao's demonic energy and knew that Yunxiao had also turned into a demon cultivator in order to accompany her.

After howling loudly, she begged Yunxiao to stop absorbing the true demonic energy immediately and return to the spiritual energy cultivator. After everything was ready, she entered the space node and smuggled into the spirit world.

Yunxiao hugged Ruyin and said:

"Silly girl, everything I have done in my life is for you. If you are afraid of becoming a demon cultivator alone, then let me accompany you."

"Only by practicing can you achieve immortality and have more time to accompany you."

"Practice hard, you won't have the heart to leave me alone, go first."

Yunxiao comforted Ruyin softly, but it made Ruyin cry even more sadly and distressed.

After crying for a long time, Ruyin stopped sobbing and raised her head to Yunxiao and said:

"I will work hard to cultivate, but you must also promise that you will never gamble with your future in the future, I will feel bad."

"If we can live forever and be together until our hearts are broken, of course it would be great. If something unexpected happens, you must live strong and take my wish to see the end of the world of cultivation."

"There will be, as long as we work hard, we will definitely see it."

"Well, I can cultivate alone, you should also cultivate well."

Yunxiao saw that Ruyin really started to cultivate, and it was not a waste of his hard work, so he calmly refined the root of the demonic energy and began to cultivate.

Ruyin also began to cultivate the Nine-Turn Soul Skill, and was also refining the hundred-year-old Fushen wine and Tuguhua wine from the sect storehouse to strengthen the soul.

Ruyin was in the middle stage of the Nascent Soul and was reclaiming the body to cultivate again. In the early stage, she was in a state of restoring cultivation.

With multiple conditions superimposed, the cultivation speed is faster than that of a single-attribute heavenly spiritual root.

In order to supervise Ruyin's practice, Yunxiao would bring Ruyin to the border of the Demon Abyss every day to practice, to prevent Ruyin from having any strange ideas.

The amount of true demonic energy absorbed every day is limited. After switching to the ancient demonic technique, the demonic energy became the basis of Yunxiao's practice.

Coupled with Yunxiao's cultivation in the realm of transformation, it can be said that Yunxiao is like a fish in water in the Demon Abyss.

What demonic energy pressure, what demonic energy erosion, it doesn't exist.

Yunxiao also went deep into the depths of the Demon Abyss to check the seal formation.

He also found more than a dozen demonic marrow diamonds at the center of the formation.

Well, Yunxiao came here to find the demonic marrow diamonds to refine magic weapons.

Practicing the ancient demonic technique, but not having the ancient demon's magic weapon, isn't it a bit out of place?

However, when Yunxiao really found the demonic marrow diamond, he gave up this idea.

Is the most important thing for Yunxiao now the magic weapon?

No, it's the cultivation, and it's the cultivation of both himself and Ruyin.

The magic marrow diamond contains a large amount of pure true demonic energy. Yunxiao took out one and tried it. He found that he could absorb the true demonic energy in it for cultivation.

Moreover, the consumed true demonic energy can be restored after the magic marrow diamond is put back into the eye of the big array.

This solved the problem of Yunxiao and Ruyin not being able to go out.

According to Ruyin's current cultivation, one magic marrow diamond is enough to absorb to the foundation-building stage.

So Ruyin avoided Yunxiao's daily wake-up service at a fixed time.

She took a magic marrow diamond from Yunxiao and went to practice in seclusion.

Ruyin's seclusion was just to give Yunxiao free time to deal with other things and to make Yunxiao feel at ease about her safety.

Yunxiao was not going to go out, nor was he going to care about the affairs of the Demon Flame Sect.

He focused on cultivation and concentrated his strength on understanding the inheritance.

Seventy years later, Yunxiao successfully broke through the middle stage of the transformation of the spirit with the help of the Thunder Guishui, the Demon Yuan Root, and the Two-Yin-Yang Transformation Sutra.

The Demon Yuan Root has the same attributes and status as the Heaven and Earth Yuan Qi Root.

The vitality of heaven and earth has declined, and the cultivators who absorb spiritual energy to cultivate can no longer break through the realm of transformation.

However, Yunxiao, who directly refined the essence of the devil, successfully broke through the middle stage of transformation.

However, Yunxiao clearly felt that the rejection of heaven and earth towards him was further aggravated.

Yunxiao now dared not use any means of the realm of transformation, otherwise the consumption of life span would be more than ten times higher than that of the early stage of transformation.

If he made a move casually, a hundred years of life span would disappear.

However, after breaking through the realm of transformation, the strength of the primordial spirit provided Yunxiao with a strong boost.

With the supplement of the magic marrow diamond, Yunxiao can definitely do it when using the peak means of the Nascent Soul. The continuous attack is like a surging river, endless.

After advancing to the middle stage of the transformation of the spirit, a magic marrow diamond can only maintain the consumption of true demonic energy for two years.

If a battle occurs, the consumption will increase tenfold and twentyfold.

Yunxiao has always been practicing in the underground demon abyss, and the magic marrow diamond is only used as an "air bag" and "power bank" when going out.

After seventy years of seclusion, Yunxiao successfully comprehended the small Xumi Vajra formation and the Xumi Vajra formation.

After comprehending thoroughly, Yunxiao found that to arrange the Xumi Vajra formation, not only a high monk is needed to be the core of the formation.

Even refining ancient treasures and activating the formation requires corresponding Buddhist enlightenment.

Yunxiao was speechless. Now he is practicing the real ancient demon skills, and he is also comprehending Buddhism. It is good enough that he does not comprehend himself into a fool.

Yunxiao can only wait to find a monk who understands Buddhism to help.

For example, the Leiyin Temple where Master Yuanzhi, who had dealt with him in the past, is very good.

The Warming Meridian Sutra has also been cultivated to the great success stage, and the meridians in the body have become four times stronger and four times more flexible.

The Nine-Turn Soul Technique has been cultivated to the fifth stage, that is, Yunxiao broke through the middle stage of the transformation of the spirit by taking advantage of the success of the fifth stage of the Nine-Turn Soul Technique and the leap in the strength of the soul.

If you practice the magic skills without a strong soul, you will either become a madman or an idiot.

Ruyin comes out of retreat once every ten years or so, and Yunxiao will replace the magic marrow diamond in her hand with a new one to avoid affecting the efficiency of absorbing the true magic energy.

Now, Bingling Ruyin has cultivated to the late stage of foundation building, and Yunxiao is very satisfied with the speed of cultivation.
