"Hahaha, good!"

Emperor Dan laughed, and with a wave of his hand, a ding alchemy furnace appeared in front of him.

The whole body of this Ding Alchemy Furnace is black and purple, huge and fine, and on both sides, it is engraved with a mighty and domineering dragon pattern, showing an indelible majesty.

Emperor Dan looked at the alchemy furnace with a melancholy in his heart, and then looked at the motionless Gu Tian and asked, "Where is your alchemy furnace?"

Lone Sky chuckled.

"Alchemy Furnace?"

"Sorry, I didn't. ”

Emperor Dan: "......"

"Your sister, you don't even have an alchemy furnace, you and I are trying to refine the elixir with the old man? Do you think that the old man and I are old, so it is easy to deceive?"

"You ......"

"Wait. ”

Gu Tian interrupted him and said, "Who said that alchemy must be made with an alchemy furnace? No wonder your old man's grade has been stuck at the sixth grade, and he has been completely dragged down by your pedantic head!"

"Just watch me perform later!"

"You...... I think you are a junior, and the old man doesn't care about you in general, so let's start quickly!"

Emperor Dan snorted coldly, and with a wave of his vicissitudes and withered arms, the medicinal herbs around him rose from the ground and flew to his side.

"Three hours of competition, how's that?"

"It's too much, an hour is enough, I still have urgent business. ”

Gu Tian said lightly, for some reason, he was very concerned about Su Luoling's situation now, so he wanted to finish refining the pill quickly, and then leave in a hurry.

"An hour?"

Emperor Dan was stammered, but then he also smiled coldly, "According to your words!"

As soon as the words fell, there was a purple fire from the Danhuang side!

The fire was ferocious, circling and burning around the alchemy furnace, instantly raising the aura in the cave several times higher.

Then, he threw the several medicinal herbs next to him into the alchemy furnace in turn, closed his eyes, raised his palm, controlled the purple fire, and refined the medicinal herbs.

Seeing this, Lone Sky was not to be outdone.

He raised his left hand and threw the three medicinal herbs into the sky, on his left palm, the heat was dissipated, and a large piece of purgatory fire burned out, like a fire dragon, emitting an incomparably hot aura, much more fierce than the purple fire of the Dan Emperor!

"What a blazing flame breath......"

As if sensing some more blazing flames, Emperor Dan immediately opened his eyes.

This, the blue flame?

Emperor Dan was dumbfounded, feeling that he had made a mistake, so he freed up his hand, rubbed his eyes, and looked at it again.

Blue flames, read that right!

But, how is this possible?

Emperor Dan thought very quickly.

But no matter how I thought about it, I couldn't think of a reasonable answer, so I had to give up in the end and focus on the alchemy furnace.

......

The fire of purgatory poured out, and the blue flames wrapped the three medicinal herbs and began to burn.

In an instant, the three medicinal herbs slowly melted from the bead shape, becoming three gases of different colors, and there was an extremely strong medicinal fragrance spreading.

The gas dispersed, and when it was about to drift into the air, it was enveloped in the blue flame and began to squeeze and merge.

At this time, Gu Tian's body began to tremble slightly, and a large amount of cold sweat also flowed out on his forehead.

"One-handed alchemy is really very difficult. ”

Gu Tian thought about it, when he released the purgatory fire and mastered the temperature of the flame to refine the elixir, he only felt that his left arm was weak, and his vitality was also lost extremely quickly!

A moment later, Gu Tian was already sweating profusely.

In the blue flame of his left palm, the three gases had melted into an extremely white round qi, and under the continuous incineration of the flames, they began to gradually solidify, absorbing a large amount of the surrounding vitality.

Emperor Dan closed his eyes tightly.

In his alchemy furnace, since all the medicinal materials were thrown into the furnace, his two hands were constantly waving to control the temperature of the purple fire.

More than half an hour has passed......

Both of them came to the final step.

That is, the most important step.

Dancheng.

Dancheng has great factor requirements, otherwise, the pill will be turned into a residual pill, so that it will be scrapped, and then lose all the medicinal properties and Dan power of the medicinal materials.

And Dancheng's requirements are three.

First of all, it is necessary to ensure that when the medicinal materials are fused into the pill, the medicinal properties of the various medicinal materials in the pill are complementary to each other, rather than fighting for territory.

Secondly, it is necessary to ensure that after the fusion of the pill, the pill power will not be lost, but will last forever.

[Of course, the longest storage capacity is no more than 100 years.] 】

And in the end, it is necessary to make the elixir spiritual, otherwise, the elixir is like a dead thing, even if it is swallowed, it will not have much effect.

But this last requirement is also the simplest.

After all, among the medicinal herbs of the Lonely Heaven, the Inner Dan of the Brute Dragon Beast had an extremely violent spirituality.

And even if there is no spirituality, only the alchemist needs to drop his essence and blood.

As for the quality of the final elixir, part of it depends on the medicinal materials, and the largest part depends on the alchemy technique of the alchemist.

......

The last twenty breaths.

Danhuang opened his eyes, raised his thumb, bit the side of his teeth, and then dripped blood into the alchemy furnace.

"Dancheng!"

The Dan Emperor shouted, and then in the alchemy furnace, there was a sound of rolling thunder, and the earth-shattering gas drilled out of the alchemy furnace, instantly filling the entire cave!

After a long time, the gas dissipated, and in front of the Dan Emperor, a golden pill was floating in the air vividly, and there was an intoxicating Dan incense!

Emperor Dan looked at the pill, nodded with satisfaction, and after holding the pill in his hand, Gu Tian's side had just finished refining.

Gu Tian's left arm waved upward, and he also grabbed the pill in the blue flame, and walked in front of the Dan Emperor with a smile on his face.

Emperor Dan looked at him with a face full of surprise, "You don't need an alchemy furnace to actually refine the pill, this is simply against the principles of heaven!"

Gu Tian chuckled, "Don't talk about this matter, let's get down to business first, what grade is your elixir, old man?"

The former laughed, touched his beard, stretched out his palm, revealing the golden elixir, and then said confidently: "The elixir refined by the old man is a solid pill at the peak of the six grades!"

Gu Tian looked surprised, and then slowly opened his left palm, and then, a white pill appeared in front of the Dan Emperor.

Emperor Dan looked closer, and his happy face began to gradually become gloomy, and then gradually surprised.

The medicinal properties of the elixir complement each other, do not lose, have longevity, and have a strong spirituality.

It's a six-grade alchemist, no doubt!

In other words, the junior standing in front of him was a sixth-grade alchemist, a sixth-grade peak alchemist who was no more than twenty years old!

After Emperor Dan's eyes left the pill, he sighed: "I really didn't expect that you are actually a six-rank peak alchemist, no wonder you refuse to inherit my inheritance." ”

"Hehe, it seems that this time, we are tied. ”

"Tie?"

Gu Tian smiled slowly, clasped the pill with his index finger and middle finger, and then turned the pill to the Dan Emperor.

"Old man, you might as well take another look. ”

Puzzled, Emperor Dan put his eyes back on the pill and began to examine it carefully.

"The medicinal properties complement each other, do not lose, have a long time, have spirituality, and are undoubtedly the six pins of the elixir...... Well...... Why do you seem to have a few cracks? The old man has some presbyopia, let me take it myself, can I?"

Emperor Dan asked.

Gu Tian naturally nodded, and then handed him the pill.

The latter took the pill, and when he brought his eyes closer, he saw the fine and complex white lines on the pill.

Suddenly, his old face was excited, his whole body trembled, and even the air around him seemed to sense his excited emotions, and began to rise and fall piece by bit!

"This, this, this...... There are even Dan lines?!"

"And if there is a Dan pattern, is it possible, this is a seven-rank pill?!"

He looked at Gu Tian, and the latter also said quietly: "The difference between the sixth grade and the seventh grade is the word Danwen." ”

"On the top of the seven pins of pills, the white veins are the beginning, the purple veins are the middle, and the gold veins are the peak. And if the eyes of this old man of yours are not mistaken, there should be a white Dan pattern on my demon body transformation pill. ”

"So ......"

Emperor Dan rushed excitedly: "So this is a seven-grade demon body transformation pill!"

Lone Sky raised his eyebrows and chuckled, "Exactly." ”
