With the injection of spiritual power, a mysterious ancient array floated underground, and the ancient array was filled with the atmosphere of desolation, which was Ling Shuang's borrowing of breath and general trend with the help of the Jiuli formation.

The golden-colored runes floating on the ancient array are not the general runes of today's formations, even those array masters can't tell the origin of the runes, the ancient and obscure characters, as if they originated from the wilderness, are natural.

The dense golden mist swam in the array, like flowing clouds under the glow, hovering between the boundless sky, and confined to the vast firmament.

The golden mist turned into a slender chain, binding the entire alchemy furnace, and looking at the furnace body carefully, it corresponded to the original formation pattern of the alchemy furnace, as well as the patterns of wear and dissipation.

After the chain spread completely, the illusion dissipated, and was replaced by the formation pattern re-imprinted on the alchemy furnace, if you let the maker of the Dan furnace look at it, you will find that the change of the formation pattern is not only a superficial structure, but also a few additions, so that the overall strength has increased by several levels.

The essence of spiritual materials is carefully roasted in the fire, slowly blending with impurities, and when the impurities are blended, there seems to be an unusual substance derived, so that the essence that is not completely blended is more completely integrated.

In Zhu Xiu's view, impurity residue is Ling Shuang's failure, but he doesn't know the true meaning.

Is it really impossible to remove impurities? It's just for other purposes.

Just like the same game, ordinary players will only see moves, and in most cases will only be led by the nose, at most one or two steps ahead, and the advantage is only on the surface.

And what Ling Shuang did was a real game, and the impurities were just failures in the eyes of others, but was it really the case?

There is no shortage of people in the world who take things out of context, and how can the analysis of the situation be different?

In the game of the strong, the finishing touch that can reverse the situation is often those inconspicuous falls, or even failures, and only at the right time will the true face of Lushan be revealed.

The impurities left by Ling Shuang are exactly like this, people who think they are impurities, they don't understand the intention, if they are just refined with essence, the pill they get is just ordinary, even with the attainment of the Dan Demon, they can only be promoted to the Divine Pill.

Impurities are the true essence of spiritual materials, a single kind of nature can not see the clues, when several different impurities are mixed, there will be great changes, and in the subsequent essence blending, guide the reaction changes of raw materials.

To a certain extent, it can be said that the impurity mixture product is a catalyst, which not only strengthens the binding of raw materials, but also greatly shortens the cultivation time.

The duel between the masters often lies in the slightest gap, and the combination of Ling Shuang's enhancement and the shortened cultivation time are more than one step better than the Peach Blossom Pill that the Dan Demon has never cultivated.

Of course, the above argument is based on the refining of the same kind of pill, and Ling Shuang would not use ordinary pills to compare, in the Jiuli classics, the Peach Blossom Pill is just an ordinary pill, and today's respect is still due to the discontinuation of the prescription.

The elixir refined by Ling Shuang is also a divine pill that does not exist in the world, and in front of that kind of divine pill, the Peach Blossom Pill is completely inadequate, and it can even be said to be commonplace.

As a divine pill, the refining steps are naturally very complicated, and after Ling Shuang deduced it, he discovered a shortcut, a shortcut to catalyze the reaction with impurity mixtures.

It can be said that impurities are resources that are used in the wrong place.

It is integrated with the essence, and has some of its characteristics, that is, it is the best adjuvant to mix, which can greatly speed up the mixing, and as for the impurity of the elixir, it is also recorded in an alchemist's notebook, but in the treatment of impurities, no attempt has been made.

Until now, impurities have been developed by Ling Shuang for new uses, which increases the utilization rate of impurities, not only speeding up the entire alchemy and cultivation process, but also pushing the medicinal power to the limit, while other refining methods often lose the essence in the long refining process, and the medicinal power is reduced.

The blending was carried out, and it didn't take long for the Dan embryo to be formed, and in the perception of the cultivators, the medicinal power was clearly comparable to the pill refined by the Dan Demon, and there were faint signs of transcendence.

Slowly stretched out his right hand, a blended thunder fire appeared in Ling Shuang's palm, and the powerful aura made Fan Kun's purple gold Shenyan surrender, and Dan Demon Fan Kun stared at the thunder fire, revealing an unbelievable look.

"How many years has this not happened, what is the origin of that thunder fire? Can you actually crush the purple gold Shenyan?! ”

A trace of flame appeared in the thunder fire, no longer as brilliant as before, even more dim than ordinary fire, but it still made the purple gold Shenyan surrender, and the flame slowly roasted around the dan, without the slightest danxiang overflowing.

Why is this flame so dim? Why doesn't this pill have a danxiang?

These two questions appeared in Zhu Xiu's mind, but he still didn't dare to despise Ling Shuang, especially the alchemist who was slapped in the face on the issue of impurities, including the alchemist surnamed Wu.

Dan Mo seemed to think of something, sat up in shock, and said, "Isn't that cluster of flames to the point of returning to the basics?!" ”

When Fan Kun stepped out of his mind, the cultivators also came to their senses, and no longer continued to judge the flames by color, and the clusters of flames were no longer within the scope of the law.

Since the flame is not in the scope of cognition, the pill is also a truth, it is indeed correct to judge the strength and weakness by momentum within a certain range, but the category also has a limit, and it just so happens that neither is in the category.

No matter how brilliant the flame is, it will eventually be extinguished, and if the temperature is hidden, it will not be easily extinguished, and only such a flame can remain eternal.

The diffuse degree of Danxiang is indeed the standard of medicinal power, if the medicinal power is fully imprisoned in the elixir, how can it be regarded as such an ordinary standard, even the slightest Danxiang containing medicinal power is not leaked, this is the real peerless elixir.

The Divine Pill has no fragrance, but it is brewing powerful medicinal power, and even derives an imperceptible coercion, which makes the cultivators feel a pang in their hearts, and under this coercion, even the sky feels it, and there are a few muffled thunders.

Ling Shuang collected the flames, and turned into a trace of thunder, which surrounded the elixir, and the cultivation had already been completed under the roasting of the flames, and the impurities that were used as a catalyst for blending evaporated out of thin air in the thunder.

In the refining process, it is necessary to mix additives, even if it is a pill, it cannot be removed, and in order to maintain the balance of medicinal power, it is not easy to remove, as for the elixir of Lingshuang, the additives are impurities, and the medicinal power is also fully blended to balance, there is no need for existence at all, at most a trace of residue can be.

In order to sublimate the medicinal power, Ling Shuang decided to remove part of it, and it was this action that made the Divine Pill completely reveal its essence, and the impurities evaporated in the thunder, leaving only the glaze-colored elixir, and the heavenly thunder also fell at this moment.

This is the Dan Tribulation, the baptism of the birth of the true Divine Pill.
