In the crypt, Cao Ying's hand gently left the medicine pod, she took a deep breath, her palms spread out, and two white flames with a touch of purple heart slowly rose up.

Inside the blood-red Dading, a raging flame suddenly burned.

"What is this?"

Julie said: "This is the Earth's Heart Yang Fire in the Transformation Fire, which is refined from the cherished medicinal herb Earth's Heart Bead, although the grade is not very high, it has a special function that can increase the success rate of alchemy." ”

As the temperature inside the medicine tripod gradually climbed, Cao Ying's jade hand fluttered slightly, and more than a thousand small jade bottles flew over the medicine tripod in a neat and orderly manner, the jade bottles tilted slightly, and slowly injected a drop of fire attribute demonic beast's blood into the medicine tripod.

Ziyi frowned, and a strong smell of blood spread from the medicine pod.

As the last vial of blood was poured in, Cao Ying's slender jade fingers suddenly flicked a few times. And with the flick of her fingertips, a cluster of flames in the medicine pod poured out of the pod, and it quickly dissipated. A thousand purple and red rays suddenly poured out from within the blood ding.

Cao Ying's soul perception was completely immersed in the medicine tripod at the moment, she kept controlling the temperature of the earth's core yang fire in the medicine tripod, and the earth's heart yang fire also kept dancing enchantingly under her control.

The flames continued to refine the plasma in the pod, and at this time, her eyes glowed with a light of extreme concentration and enjoyment.

Ziyi sighed with emotion, even though she was imprisoned in a small square tower and forced to refine medicine for sixteen years, it was undeniable that she did have a fanaticism and obsession with refining medicine in her heart. If it weren't for that, she wouldn't be where she is today.

The white-purple flames in Cao Ying's palm kept surging, and clusters of flames burst out from time to time, and then dissipated. However, the strong bloody aura became more and more intense.

"Up!"

With Cao Ying's soft drink, a soft inky black liquid slowly floated up from inside the medicine pod, which should be the plasma of more than a thousand fire-attribute demonic beasts mixed together.

Suddenly, Cao Ying's two slender and white middle fingers like ivory stretched out to her ruddy cherry lips, Cao Ying bit her teeth, and two drops of red blood gushed out from her fingertips, Cao Ying flicked her fingers and flicked the two drops of blood and flew towards the medicine ding.

The two drops of crimson blood had just been stained with the inky black liquid, and with a snort, the calcined into a mass of inky black plasma, suddenly became agitated, and a faint luster slowly spit out from the plasma.

Cao Ying's hands kept dancing, and the earthly yang fire that rushed out of the medicine tripod became more and more violent, but the purple wings on the side were shocked to find that every time Cao Yingyu's hand danced, there were two drops of blood flying towards the inky black plasma at the fingertips.

Cao Ying was engrossed in controlling the temperature of the flames in the medicine pod, and at this moment, as long as the temperature was slightly higher, this inky black plasma would be calcined into a cloud of empty air.

The sky had gradually turned white, and wisps of morning light could already be faintly seen at the entrance of the cave, and at this time, the inky black liquid, after the continuous burning of the flames, began to slowly dilute a little yellow impurity outward.

Looking at the yellow impurities that appeared on the surface of the plasma, Ziyi seemed to hear Cao Ying's deep exhalation.

Cao Ying took a deep breath again, and with a flick of her jade fingers, the small cloud of yellow impurities wrapped in the inky black plasma was separated from the plasma by her.

Purple Wing was stunned for a moment, was it his delusion? The inky black plasma seemed to have become less black after the yellow impurity had been diluted out.

After expelling this mass of yellow impurities, countless impurities of different colors appeared one after another, and these impurities were all cleaned up by Cao Ying without exception.

Plasma the size of a fist is now the size of a thumb. And the deep inky black plasma had completely transformed into a dazzling red drop of blood at this time.

It seems to be similar to him refining blood essence.

It was already the most critical time, Cao Ying couldn't help but take a deep breath again, and waved her palms violently, the white-purple flame in the medicine pod surged up a foot, and the surrounding temperature also rose sharply, and the flames that came out of the medicine pod completely condensed into a sharp tongue of fire, and the tongue of fire kept scorching the bright red blood droplets suspended above.

At this time, there was an ape cry from outside the cave, and suddenly the bright red blood droplets seemed to be unable to withstand the scorching flames anymore, and exploded like a brilliant firework in front of the three of them.

Purple Wing's heart thumped, was this a failure?And Julie's hand was also tightly twisting Purple Wing's arm at this time.

After the brilliant fireworks dissipated, a flame so red that it would sting the eyes slowly bloomed on top of the medicine pod.

Cao Ying took a deep breath, spread out her right hand, and the extremely bright red flame flew towards Cao Ying's palm.

This flame was extremely bright red, and the bloody qi and fresh blood that emanated from it were even inferior to it, and in the midst of the flames, a small purple figure could be faintly seen in it, like a fire spirit, constantly churning and flying in it......

"Is this done?"

Purple Wing looked at Julie wordlessly, and Julie was also looking at him at this time.

"It should be done,"

The two communicated silently.

......

"How is it possible! There was a purple aura in the flame heart!"

Cao Ying screamed in surprise, and then her eyes couldn't help but glow with a touch of moisture.

"Blood Demon Fireworks, it's actually the top-level Blood Demon Purple Heart Flame!"

Cao Ying excitedly held the Blood Demon Purple Heart Flame in her hand and rushed towards Julie.

"Sister Julie, I succeeded! I am still the top Blood Demon Purple Heart Flame among the Blood Demon Fireworks!"

"Congratulations, Miss!"

Julie smiled, her eyes couldn't help but glance at Purple Wing.

"Sister Cao, congratulations. ”

"......" Ziyi looked at Cao Ying resentfully.

At this time, Cao Ying ignored him completely, and the whole person was immersed in that incomparable joy.

It took a quarter of an hour for Cao Ying to come out of the magic barrier of incomparable joy.

She took a deep breath and said, "With this blood demon firework, I will be a little more sure of refining that seventh-order Yin Yang Xuanlong Pill." ”

"What, Sister Cao, what are you talking about, what you want to refine is the Yin Yang Xuanlong Pill?" Zi Yi was stunned for a moment, he heard it right.

Cao Ying looked at Ziyi: "You protect the Dharma for me, and I want to practice the Yin Yang Xuanlong Pill." ”

He heard it right!

This pill is so impressive to him, he has taken the anti-inflammatory medicine, and it is even more at the end of his life, helping him break through and stand up, and successfully break through Douzun.

Of course, he knew that Cao Ying practiced this elixir and would not give it to him. But he was still very excited, he hadn't seen anyone practice pills, and it was still such a high-grade pill as the Yin Yang Xuanlong Pill.
