"Teacher, didn't you ask me to promise her?"

Xiao Yan scratched his head and said with some embarrassment.

"I'm asking you to promise her, but you can't say yes so easily, at least you have to bargain.

Those medicinal herbs are refining the four-pinned pill, do you think the four-pinned pill is jelly bean..."

After educating Xiao Yan again, Yao Lao's voice finally fell silent, and Xiao Yan was also embarrassed and did not speak.

After a while, Yao Lao sighed softly and said lightly: "Since you have promised others, now let's go to refine the medicine first." ”

"Okay, teacher."

After answering, Xiao Yan walked towards the back mountain.

......

In a cave in the mountain behind Xiao's house, Xiao Yan sat cross-legged on the ground, and Yao Lao's almost transparent body floated in the air.

"I don't know who Concubine Ya is helping to ask for medicine, and she can actually take out three precious soul medicinal materials at once."

Looking at the three medicinal materials in front of him, there was no lack of surprise in Yao Lao's tone.

"Teacher, according to you, what kind of pill can be refined from these medicinal materials."

Xiao Yan blinked, looked at Yao Lao and asked.

"Most of the soul medicinal materials can be made into pills alone."

Yao Lao slowly landed on the ground, picked up the three medicinal materials placed on the ground and said, "And these three medicinal materials are indeed rare fusion pills, and I don't know if Na Yafei did it on purpose." ”

Nodding as if he didn't understand, Xiao Yan turned his head to look at the medicinal herbs on the ground and said, "It's rare to have this opportunity, and I also ask the old book to make alchemy, and I can also observe and observe." ”

"It's okay, it's also a good opportunity for you to observe the refining of high-grade pills up close."

Yao Lao nodded slowly: "Take out the medicine ding." ”

"Good teacher."

Xiao Yan excitedly took out the ring from his arms, and after his mind sank into it, a red medicine pod of about half a meter appeared in front of him out of thin air.

The whole body of Yaoding is dark red, and there are two hideous snake heads carved on it, and the open snake mouth forms two interconnected fire holes, the hollows are curved and continuous, and the deeper they go inside, the smaller the diameter.

On the lid of the top section of the medicine pod, there is a hole the thickness of a baby's arm, which is a special place to put medicinal materials.

"Look!"

Yao Lao floated in front of the medicine ding, and with a flip of his palm, a cluster of beating white flames appeared in his hand, which was the cold fire of the bone spirit.

With the appearance of the cold fire of the bone spirit, the temperature in the huge cave suddenly dropped, and it instantly felt as if it was in an ice cellar.

Immediately afterwards, I saw that the old medicine man's palm shook, and the cold fire of the bone spirit in his hand quickly rushed into the medicine tripod.

"Bang!"

With a soft sound, the cold fire of the bone spirit flipped back and forth in the medicine tripod, and then it rose and burned.

"The most important thing in refining medicine is to control fire, which is also the first step in refining medicine."

Yao Lao's faint voice sounded, and he continued to wave out the Dao palm wind in his hand, rushing into the medicine ding.

After a while, under Yao Lao's control, the beating flames gradually fell silent.

"Each medicinal herb must first refine the essence of the medicinal power in it, this time, we will first put in the White Jade Earth Spirit Fruit."

As soon as the words fell, Yao Lao grabbed a crystal clear fruit on the ground, and with a flick of his fingers, he flicked it into the medicine pod.

The moment the white jade spirit fruit entered the medicine tripod, the originally silent forest white flame jumped again, and then, under the control of Yao Lao, the white jade spirit fruit was tightly wrapped.

After a while, the White Jade Earth Spirit Fruit quickly began to shrink, and on its surface, drops of transparent liquid like water droplets began to seep out.

After the last drop of transparent liquid of the White Jade Earth Spirit Fruit was refined, the entire fruit body turned into a cloud of ashes and sank to the bottom of the medicine pod.

Smiling slightly, the medicine elder made a move with his palm, and the transparent liquid wrapped in the cold fire of the bone spirit was sucked into the medicine pod, and then carefully packed into a jade bottle by him.

Next, Yao Lao repeated the previous action again.

The Soul Rejuvenation Grass was refined into drops of green liquid, while the Spirit Rhino Flower was baked into a milky white powder by the Yao Lao.

"The next thing is integration, which is also the key to Cheng Dan."

Yao Lao skillfully grabbed the three extracted materials, and then threw them into the medicine tripod one by one.

Immediately afterwards, the white flame of the medicine pod Nathan beat rapidly, tightly wrapped the three materials, and began the most violent calcination.

With the calcination of the flame, the three materials began to slowly and gradually fuse, and as time moved, the prototype of a potted elixir gradually appeared faintly in the medicine pod.

"The last step, Ning Dan!"

While drinking softly, Yao Lao's face also became cautious.

In the medicine pod, the white flame seemed to be suppressed by an invisible force, and it turned docile.

A full quarter of an hour later, under the suppression of the cold fire of the bone spirit, the two white round pills finally took shape.

With a move of the palm, two pills flew out of the medicine tripod with a 'bang', and were grabbed by the medicine elder in his hand, and immediately put them into two jade bottles.

"Teacher, how do you refine two pills, isn't the medicine strong enough?"

Xiao Yan looked at the two jade bottles on the ground and asked questions.

Originally, the medicinal materials that could only refine one pill were forcibly divided into two, and the medicinal power was naturally divided into two.

In other words, the pill that Yao Lao refined was originally four grades, but now after being divided into two, it can only be regarded as a pseudo-four grade.

"Stupid, if I spend my soul power refining the elixir, you will receive an Ice Spirit Flame Grass as a reward."

Yao Lao glared at Xiao Yan, pointed to the two jade bottles on the ground and said: "These two white jade soul pills are both soul-type pills, take one for Na Yafei to pay for it, and the rest, put it away for the time being, I may use it in the future." ”

"But, Concubine Ya, she..."

"It's nothing, just do as I say!"

Yao Lao flicked his sleeves and turned around directly.

"Okay!"

Xiao Yan nodded helplessly.

Putting away the two jade bottles on the ground, just as Xiao Yan was about to put the medicine tripod into the ring, Yao Lao suddenly turned around, "Wait!" ”

"Teacher, is there anything else?" Xiao Yan asked suspiciously.

Yao Lao stretched out his hand, pointed to the medicine tripod that Xiao Yan was about to take back, and said lightly: "You have been watching it for so long, now try to refine it yourself while the iron is hot, and you can see your own shortcomings." ”

Nodding, Xiao Yan glanced at the medicine tripod in front of him, and then sat cross-legged on the ground, his eyes slightly closed.

Immediately after, the pale yellow fighting qi seeped out from Xiao Yan's body, and finally converged on the palm of his hand.

After a moment of silence, the fighting qi burst out of the palm and burrowed into the medicine pod.

At the same time, with a turn of Xiao Yan's fingertips, an extremely meager green air flow was also poured into the medicine pod.

The moment the green air flow and the yellow fighting qi touched together, they turned into a yellow flame with a 'poof' sound, and it burned violently.

"It's been a lot of progress, at least a lot better than the last time."

Looking at the churning flames in the medicine pod, Yao Lao nodded approvingly, and said in a deep voice: "Refining Huishensan, I hope you don't waste too many medicinal materials this time." ”

"Yes, always."

There was no doubt that there was him, Xiao Yan opened his eyes, took out the medicinal materials for refining Huishensan from the ring, and then began refining the medicine under the command of Yao Lao.
