The Bone Demon didn't even have a chance to react, and was devoured.

Seeing that the Abyss Demon Empress and Zi Ruyu were dumbfounded, this was also too powerful.

After cleaning up the White Bone Demon, Yang Hongwu put the incarnation into the Little Demon Realm and digested the power of the White Bone Demon.

"I didn't expect you to hide so deeply. "The Abyss Demon Empress is a little palpitating, if he had dealt with her like this in the first place, then would she still be able to survive?

"Okay, now that we don't have anyone to disturb, we can set it up and start alchemy. Yang Hongwu took out a formation plate.

"Nine Heavens Xuan Thunder Array, open!"

With a light snort, a huge formation rose into the sky, enveloping the three of them in it.

"You protect the Dharma for me, and I'm going to start alchemy. Yang Hongwu casually arranged a small formation, and then entered the formation and began alchemy.

The two women sat cross-legged.

Yang Hongwu began alchemy.

Take out the Heavenly Spirit Grass, and take out the elixir one by one.

Breaking the Holy Pill, it is not so easy to refine, but fortunately, Yang Hongwu got the supreme alchemy method, which is extremely mysterious.

"Open!"

A huge Dan furnace appeared in Yang Hongwu's hand, and the Dan furnace continued to rotate, and clusters of yin and yang flames poured into the bottom of the Dan furnace.

After reaching a certain level, Yang Hongwu waved his right hand, and the Heavenly God Spirit Grass entered the Dan Furnace.

If it weren't for refining the Holy Pill, Yang Hongwu wouldn't even need to use the Dan furnace to refine it, but refining the Holy Pill was foolproof, and if he wanted to refine it, he would refine it best, so Yang Hongwu would use the Dan furnace, which was not an ordinary Dan furnace.

Although this is not an imperial artifact, it is also a celestial artifact.

The Heavenly God Spirit Grass, the medicinal power is extremely domineering, and when it enters the Dan Furnace, the entire Dan Furnace begins to beat, making a buzzing sound.

Yang Hongwu knew in his heart that this was because the medicinal power of the Heavenly God Spirit Grass was too strong, and although Yang Hongwu erased his consciousness, it was also very terrifying.

The medicinal power is frantically impacting the Dan furnace, but fortunately, this Dan furnace is a heavenly weapon, if it is an ordinary Dan furnace, it is estimated that the blockade has been broken by now, and the Dan furnace is broken.

"Alchemy. ”

Yang Hongwu shouted softly, and a mysterious power erupted from Yang Hongwu's right hand and shot into the Dan furnace, and the Dan furnace, which was originally beating wildly and seemed to be about to explode, suddenly quieted down.

However, Yang Hongwu knew that this Heavenly Spirit Grass was too domineering, and there was no way to become a Dan if it was refined like this.

Therefore, Yang Hongwu needed to find other elixirs to assist in neutralizing the domineering medicinal properties.

Then Yang Hongwu raised his right hand, and one by one the elixirs flew over, the Dan furnace opened, and those elixirs quickly entered the Dan furnace one by one.

Yang Hongwu's speed is getting faster and faster, and it is getting more and more amazing.

When he was refining the pill, his technique was extremely mysterious, and it was not comparable to ordinary people at all, outside the formation arranged by Yang Hongwu, the Abyss Demon Emperor and Zi Ruyu were shocked to the extreme when they saw Yang Hongwu's alchemy methods.

This kind of alchemy technique is simply unheard of, I'm afraid even Emperor Dan can't do it, right?

Could it be that Yang Hongwu's attainments in alchemy have already surpassed the powerhouses of the Dandi realm?

shook his head, although he was unwilling, he had to admit that Yang Hongwu's attainments and talent in alchemy were probably unparalleled.

It's tough.

At this time, Yang Hongwu controlled all the elixirs in the Dan Furnace, and opened a key step in alchemy, turning the elixir into liquid, refining all the elixirs into liquid.

This is a very critical step, although it is not the most critical, but if something goes wrong, it is very troublesome.

Yang Hongwu's control of the Dan Furnace had already reached an incredibly proficient level.

The Heavenly Spirit Grass began to melt, and the fire of yin and yang was brought into full play.

This is a powerful fire control technique, although Yang Hongwu is not an innate spiritual fire battle body, but the control of flames is no worse than the innate spiritual fire battle body.

Coupled with that mysterious fire control technique, it has reached an incredible point.

With his huge spiritual power, he was able to perceive little by little, every trace of subtle changes.

"Melt!"

A word was spit out, and Yang Hongwu made a mysterious seal with both hands.

After the Celestial Spirit Grass melted, all the elixirs melted and turned into a rich medicinal liquid, which was filled with majestic spiritual power.

The great spiritual power is shocking.

Now comes the second step.

This step is to remove the impurities of the liquid medicine in the Dan furnace.

This step is related to the grade of the pill, the less impurities contained in the pill, the higher the color grade of the pill.

For ordinary alchemists, refining the Holy Pill, if they can refine a good product, it is already very good.

However, Yang Hongwu didn't just want to refine good products, for him, if he refined good products and didn't reach the treasures, it would be a failure.

Of course, his highest goal was to refine the Ultimate Pill.

The best holy pill, only the best pill, the effect is the best, the most powerful, without the slightest sequelae.

If it is a good product, or even a treasure, if you take too much of the refined pill, it will form erysipelas in the body, and once it accumulates to a certain point, it will be impossible to make any progress in the future cultivation, and erysipelas will destroy the cultivator's physique and block the meridians.

Even some terrible erysipelas will contaminate the cultivator's primordial spirit and soul with impurities, and that kind of situation is very terrifying.

Therefore, for those geniuses and demonic geniuses, their battle bodies are strong, their qualifications are extremely strong, and their talents are against the sky, when they cultivate to improve their realm, they generally do not take pills to cultivate to improve their strength.

However, if it was the best elixir, then this would not be the case.

And when Yang Hongwu takes the pill, he will pay attention to this, if it is not the best pill, Yang Hongwu will not take it.

In Yang Hongwu's eyes, the general pill is a scum, a poison, a garbage, and not worth mentioning.

"Burn!"

A word was spit out, and his hands punched out one flame seal after another, and these seals made the flame incinerate the impurities in the liquid medicine a little bit.

Little by little, these impurities were incinerated and turned into powder, which was excreted little by little along with the residue excretion channel of the Dan furnace.

These black impurities fell on the ground, which was so amazing that even the ground was corroded.

Seeing this scene, the Abyss Demon Empress and Zi Ruyu were very shocked and extremely surprised.

In this Heavenly Spirit Grass, there are such terrible impurities and toxins, and if these impurities and toxins are in the body, the damage to the body is very terrible.

Especially the Abyss Female Demon Emperor knows this best, because her cultivation realm has reached the Great Emperor Realm, and only the powerhouses of the Great Emperor Realm can have such a thorough understanding of her body.
