Feng Ruo's choice is, of course, the second refining method.

If it was said that in the previous Qi refining period, and even in the foundation building period, his goal was only to be stronger and have more longevity, then after advancing to the Jindan stage, his goal was to go further, because he was no longer the ordinary and ordinary little cultivator he used to be.

In the past two hundred years, every difficulty, every calamity, and every breakthrough he has experienced will increase his self-confidence, and to this day, he can completely achieve the same position as those so-called cultivation geniuses!

Although he had no intention of comparing or showing off, he knew that he could do better!

Therefore, an excellent natal flying sword is a must for him.

Of course, this second refining method was extremely difficult and dangerous, so Feng Ruo didn't dare to be reckless.

At this moment, in the quiet room specially used for cultivation, Feng Ruozheng was meditating cross-legged, but in front of him, there were nine whole pieces floating like the size of a fist, all black, but there was another kind of dazzling light, this was the obsidian that he had refined for ten months before, originally there were fifteen pieces in total, but he left six pieces for refining the broken gold sword, and these nine pieces of obsidian were used to refine the natal flying sword, so far, the obsidian original ore he had made from the forbidden land of the ancient gods was completely exhausted!

According to Feng Ruo's plan, these nine obsidian stones were used to refine the main body of the Natal Flying Sword, and it was also the first step in refining the Natal Flying Sword.

However, at this time, these nine refined obsidian stones cannot be put into the cultivator's golden pill to be refined, and they must be used as a medium to arouse their spirituality before they can be put into the golden pill and tempered with the golden fire, and the process must be extremely careful!

Fortunately, Feng Ruo already had a lot of experience in initiating the spirituality of refining materials, and he had used this obsidian many times, so this process was not very difficult!

At this time, as Feng Ruo's magic trick continued to be played, a faint silver light appeared on the surface of the nine obsidian stones one by one.

After all the nine pieces of obsidian were wrapped in silver light, Feng Ruo bit the tip of his tongue, and a mouthful of blood turned into thousands of tiny runes, completely submerged in the nine pieces of obsidian.

Although it seemed that the nine pieces of obsidian had not changed from the outside, Feng Ruo's divine mind could feel the state of the nine pieces of obsidian, as if he had come to life, and he could even vaguely sense the small gap between the nine pieces of obsidian that looked exactly the same, as well as the quality of each piece.

This is the effect of spirituality!

Of course, this kind of spirituality is a two-way street, if Feng Ruo's realm can't be reached, even if he stimulates the spirituality of obsidian, he can't feel it, and naturally it is useless.

After maintaining a few breaths in this state, the magic in Feng Ruo's hand changed again, and this time, the nine pieces of obsidian slowly disappeared into the silver light, and in the end, all that was left was nine clouds of silver light.

At this moment, Feng Ruo suddenly opened his mouth slightly, as if he was exhaling, and then a touch of brilliant golden pill like the morning sun spit out from his mouth!

At the same time as this golden pill appeared, tiny golden thunderbolts swept through the entire meditation room, and even countless tiny clouds of smoke appeared out of thin air.

This is the effect of Jin Dan communicating heaven and earth, in a sense, it is already a magical power to call the wind and rain, and this is still in the quiet room blocked by many formations, if it is in the open field, it can even affect all the heaven and earth vitality within a radius of a hundred miles.

Of course, that is also an extremely risky approach, and if someone sneaks up or disturbs it, it will definitely be a disaster for the cultivator!

At this time, when the sealed golden pill hovered in the air, a formless and colorless, seemingly flame-like existence wrapped the silver light formed by the nine pieces of obsidian, which was the unique Dan fire in the golden pill.

This Dan Fire is not a flame in the ordinary sense of the word in the world of cultivating immortals, or even two completely different things, because this Dan Fire does not have the characteristics of an ordinary flame, in fact, the essence of this Dan Fire can be described as the purest mana, it is the source of all the mana of the cultivator, and it is also the source of all the magical powers of the cultivator.

If Jin Dan is the essence of the cultivator's whole body mana, then the Dan Huo is the core essence of the Jin Dan, it can be said that this Dan Huo can even represent the full strength of the cultivator!, which is why Feng Ruo must use the Dan Fire to quench all the materials, and use this to refine the Natal Flying Sword, because the power possessed by the Dan Huo may not be the strongest, but the materials it has quenched will definitely be the most suitable for the cultivator!

At this time, seeing that this Dan Fire was enveloping the nine clusters of silver light, Feng Ruo also relaxed a little, and while maintaining control of his Jin Dan, he also had to inspect the situation of the nine pieces of obsidian.

You must know that the power of his Danhuo is not weaker than his Xuanhuo clone at all, or even stronger, after all, it is an existence that is equivalent to condensing the mana of his whole body, and it must not be underestimated!

Don't look at these nine pieces of obsidian are all thoroughly refined, but it won't take long for them to be dissolved by that Danhuo, but that is not the effect that Feng Ruo wants, what he needs is not to let this obsidian stone open, but to refine it repeatedly until it meets his most perfect standard!

Therefore, it must be properly controlled, and there must be no mistakes!

When time passed little by little, after a full six hours, the nine pieces of obsidian that were originally as large as a fist had shrunk to the size of a dragon's eye, and the layer of silver light outside had become more agile and transparent, which was breathtaking.

And at this time, Feng Ruo's expression was already extremely tired, after all, it was extremely rare to let Jin Dan leave his body for so long, he was still only in the early stage of Jin Dan, far from being able to support it for a long time, fortunately, this first stage of tempering had been completed perfectly.

With the rotation of his mind, the nine pieces of obsidian that had shrunk many times were brought back to the golden pill by that touch of danhuo, and then, Feng Ruo opened his mouth again to swallow the golden pill back, and now he had to breathe well, and only after the danhuo in the golden pill was replenished again could he continue the next step of refining.

And this kind of pause is also very normal, because there is a Dan fire in the golden pill that is always warming the materials that have been refined, so there is no problem.

This is also the benefit of refining the Natal Flying Sword, and it doesn't have to be done in one go like refining those magic weapons. [Text provided by]
