"In order to successfully obtain this "Bone Spirit Cold Fire", I stayed in that dark ghost place for eight years, and at the moment of final absorption, I was well prepared, and I was almost burned to ashes by this ghost thing..."

"Hehe, although the danger is extremely high, as long as you can get the fire, everything is worth it. As long as he has a different fire, not only will the medicinal power of the elixir refined be stronger, but when he is against someone, a strong person of the same level will not dare to collide with it at all. Yao Lao sighed: "This Danzun can also refine the cold fire of the bone spirit, and I am also destined for him! It's just that I have never heard of his reputation before, it should be that when I walked the continent, he happened to be looking for a strange fire in the extreme north!"

"Coincidentally, he also has a strange fire, and you will practice the burning technique in the future...... Hehe!" After saying that, Yao Lao's voice became a lot colder.

To cultivate the Burning Technique, it is necessary to refine the alien fire, but how can the alien fire between heaven and earth be so easy to find. But now, there is a cold fire in front of him, and he really encounters a sleepy person who sends a pillow, how can Yao Lao not be happy?

Nalan Yanran couldn't hear Yao Lao's words, and Nalan Yanran didn't know about Yao Lao's calculations.

At this time, Nalan Yanran was concentrating on refining medicine.

"Healing medicine, a blood-clotting herb, a living qi fruit, two poppies......"

In the narrow cave, the flames in the medicine tripod were reflected on the mountain wall, and the teeth and claws were constantly beating.

Nalan Yanran stared intently at the churning flames in the medicine pod.

Refining medicine for a long time is an extremely consuming job, and with Nalan Yanran's current cultivation, it is also difficult to continue. But fortunately, there is a system, and this bone spirit cold fire is also the flame of the rental system, which only needs to consume points, and does not need to consume her physical strength and fighting spirit, so the aura on Nalan Yanran's body has not changed much, otherwise it is difficult to hide from Yao Lao.

I don't know how long it took, Nalan Yanran slowly put away the cold fire of the bone spirit.

In front of her, there were more than a dozen jade boxes placed in front of the medicine pod, and the jade boxes were filled with white powder. These are all purified from the medicinal herbs just now.

"These medicinal powders are the essence of the medicinal materials, if you want to refine the medicine, this step is essential, only by purifying the purest medicinal powder, the success rate will be greatly improved when refining the medicine. Identifying the medicinal power of the medicinal powder is the key to distinguishing whether the medicinal powder is pure or not. ”

After a pause, Nalan Yanran looked at Xiao Yan and said lightly: "You should be familiar with the pills and the medicinal properties of each medicinal material!"

Xiao Yan was a little confused, and nodded subconsciously.

Call......

Nalan Yanran ran for a while, a strong wind blew out, and suddenly, more than a dozen medicine boxes fell down one after another, and all kinds of medicine powders were disrupted!

"Use what you've learned about medicinal properties to reclassify the messed up powder!"

Yes?

Xiao Yan is stupid! There are so many medicinal powders, they all look similar, how can they be different?

Identification of medicinal properties from color, smell, taste, properties......

Xiao Yan recalled the methods recorded in the ancient books, and began to distinguish them with a bitter face.

However, these medicinal powders are almost the same, and they are mixed together, and the smell is mixed, and you can't smell it at all, so you can only taste it!

Xiao Yan dipped his fingers in a little white powder and stuffed it into his mouth.

Phew......

It's so bitter!

Xiao Yan's face turned into a bitter melon.

"It's ...... "Fortunately, it's not hard to discern.

Immediately, it is a faint red powder.

"I know, this must be the fruit of vitality!"

The Vitality Fruit is red, and this powder must be the Vitality Fruit.

It's a good thing, it can speed up the fighting spirit.

Among these medicinal materials, the Vitality Qi Fruit is the most expensive.

Xiao Yan grabbed a handful and stuffed it into his mouth, good things, don't eat them for nothing!

However, the next moment, his expression stiffened slightly, and in an instant, a strange red color started from his neck and went straight to the Heavenly Spirit Gai, and even his hair launched a red light, as if it was about to burn!

"It's so spicy—" Xiao Yan stuck out his tongue, and his lips swollen into sausages. Tears and snot remained.

This is not a living qi fruit, it is simply a fire qi fruit! Xiao Yan felt that his whole body was about to burn.

Xiao Yan wanted to cry without tears, feeling that he had been pitted miserably.

What kind of rejuvenating fruit is this? This is clearly chili noodles! Moreover, it is chili powder that has been purified to the extreme.

After drinking a large tank of water, his stomach was a little round, and Xiao Yan barely settled down a lot. However, the lips are still two sausages. Moreover, Xiao Yan knew that this was only the surface, swallowing so much chili powder essence, going to the toilet tomorrow was the biggest test.

Nalan Yanran watched this scene indifferently from the side, but she was laughing wildly in her heart, and urged: "Hurry up!"

Xiao Yan learned to be obedient this time, but simply made a little bit, and then licked it with the tip of his tongue.

Why doesn't it smell?

Lick it again...... It's a little salty!

Keep licking, it seems to be saltier!

Xiao Yan was a little puzzled, and he kept eating up all the powder in his hands, but he couldn't distinguish it.

"Yao Lao, what kind of medicine powder is this? I haven't seen any record of this kind of medicine powder!" Xiao Yan refused to lose face, and secretly asked Yao Chen in his heart.

Yaochen rolled his eyes and was speechless: "If I'm not mistaken, it should be salt!"

Sure enough, Nalan Yanran picked up a box from the ground in surprise, and said in surprise: "Why did my spice box overturn?"

Both paprika and salt fell out of this box.

However, Xiao Yan knew that this must have been deliberate by this Danzun master, otherwise, who would eat chili peppers and refine them into the most essential powder? The spicy taste has increased more than a hundred times.

After testing the medicine, Xiao Yan was already frightened, he had tasted all kinds of sweet and sour tastes, and finally distinguished all the medicinal powders needed for healing medicine.

"Next, you can try to purify the medicinal powder yourself, purifying the medicinal powder is the foundation and the most powerful step in refining medicine. ”

Call......

Xiao Yan let out a long breath, and he could finally start refining medicine.

Nodding, Xiao Yan touched the fire mouth, his eyes were slightly closed, the light cyclone in his body fluctuated slightly, and a stream of light fighting qi gushed out, and finally illuminated his palm slightly yellow.

The pale yellow fighting qi, after reaching the palm of the hand, was slightly silent, and then as if it was subjected to a violent suction, it actually burst out of the palm, and then through the fire mouth, it drilled into the medicine pod.

"Poof..."

With a muffled sound, the light yellow air flow was abruptly transformed into a light yellow essence flame after passing through the fire mouth, and it was constantly churning and burning in the medicine pod.

The palm of his hand suddenly erupted into flames, which shocked Xiao Yan's heart, and he almost reflexively withdrew his hand, but fortunately, after sensing that the palm of his hand was still cold, he suppressed the panic.

"Well, it's not bad, you can transform into flames the first time. ”

After recalling Nalan Yanran's actions just now, Xiao Yan's soul perception gradually invaded the medicine tripod, trying to control the relatively gentle flame.

His fingers flicked on the ring, and a somewhat dark red blood coagulation grass appeared in his palm, and after a little hesitation, Xiao Yan threw it from the entrenched snake head on the top of the medicine tripod.

As soon as the blood condensation grass entered the medicine tripod, Xiao Yan didn't have time to control it, the flames fluttered up, and in an instant, a blood condensation grass turned into pitch-black ashes, and was finally expelled from the ding by the special settings in the medicine tripod.

Looking at his first mistake, Xiao Yan smiled awkwardly.

"Go on. Nalan said lightly.

Swallowing a mouthful of saliva, Xiao Yan threw a blood condensation grass again, this time the blood condensation grass persisted in the flames for a while, but it still turned into pitch black ashes.

"It's hot. ”

Wiping a handful of cold sweat, it was his turn to refine the pill by himself, Xiao Yan finally knew that this work was really not something that anyone could easily handle.

After persistently burning more than twenty blood-coagulation grasses, Xiao Yan finally reluctantly touched the adaptation point of blood-clotting grass to temperature.

Throwing in a blood condensation grass again, Xiao Yan's face was solemn, his soul perception firmly compressed the temperature of the flame, and his eyes stared at the blood condensation grass suspended on the flame through the cold ice mirror.

After churning in the flames for a while, the blood condensation grass finally began to gradually shed its turf, and the juice contained in the grass blades was also smoked into a little bit of pale white powder, and the essence medicinal power in the blood condensation grass was finally successfully refined by Xiao Yan, a rookie.

"It's a success!" Xiao Yan was overjoyed, "I can start learning alchemy!"

"It's still far from it!"

Nalan Yanran took a while and blew away all the medicinal powder in front of Xiao Yan.

Xiao Yan was anxious, this was something he had worked hard to refine and purify for most of the day.

"The purity of these medicinal powders is too poor, even if they are used to refine medicines, they will not succeed, but they will waste other medicinal materials. When will the medicinal materials you refine and purify reach 100% purity, I will teach you to refine the medicine again! If you can't even do this, you don't want to learn to refine the medicine!" Nalan Yanran said mercilessly, and after speaking, she turned around and left without hesitation.

Looking at the back of the departing black robe, Xiao Yan's face was a little unwilling: "Yao Lao, did he deliberately target me? I think he is deliberately targeting me!"

Yao Lao was silent for a while, and said lightly: "I think that although he is a little stricter, what he says is very reasonable. Refining medicine is originally the most precise operation, and the more advanced the elixir, the more rigorous the steps required, and the more rigorous it needs to be. Purifying medicinal materials is a basic skill, if this is not done well, even if some low-grade medicinal materials do not have great requirements for purity, however, high-grade medicinal materials cannot be successful. Thousands of tall buildings rise from the ground, I think he is for your good!"

"Even you can help him speak!" Although Xiao Yan understood, he was still a little indignant: "How can there be 100% purity in the world? How can there be impurities, and they are not molecules!" he took out the little knowledge he had learned in his previous life to refute.

How does the medicine elder know what the molecule is? said lightly: "100 percent not necessarily, but a senior alchemist can achieve at least 99 percent purification, and what you just did can only be said to be simply refined into medicinal powder, and you can't even reach the passing grade!"

Xiao Yan pursed his lips, no longer contradicted, and honestly began to refine the medicine.

Half a year has passed in a flash.

During this period, Xiao Yan studied refining medicine during the day every day, refining various medicinal materials, purifying medicinal powder, and cultivating at night.

Although he has been in contact with refining medicine for half a year, he has not really practiced a complete pill, and he is constantly repeating the action of refining the medicinal powder every day.

Nalan Yanran did what she said, Xiao Yan didn't purify the medicinal materials 100%, so she didn't teach Xiao Yan to refine the medicine.

And Yao Lao seems to have become harsh on Xiao Yan under Nalan Yanran's way of striving for perfection. Otherwise, this Danzun is so strict with his apprentice, if he is too lax, wouldn't it mean that he is inferior to the other party? This is something that Yao Lao can't accept no matter what.

Therefore, Xiao Yan also worked hard to the extreme, and purified the medicinal powder for half a year.

He sat in front of the medicine pod every day, and his face was blackened, but the medicine powder became whiter and whiter.

On the dozen or so jade boxes in front of him, the jade boxes were filled with pale white powder extracted from the blood condensation grass, which were the results of Xiao Yan's previous efforts.

Looking at the jade box from left to right, the pale white color is getting more and more intense, and when it comes to the last jade box, the white powder in it has almost reached the texture of pure white.

Looking at this extremely obvious progress, Yao Lao nodded in amazement, the last medicinal powder, not to mention the purity of 100%, at least more than 95%, which is already extremely good.

"Your current technique of refining medicinal materials is no worse than some fourth-level or even fifth-level alchemists!"

Yao Lao also sighed, it is not easy to do one thing day after day for half a year, he sighed: "It is impossible to make great progress if you continue to purify, because, if you want to truly achieve 100% purification, only different fire can." Now, it's time to start teaching you the true art of alchemy!"

"Really?" Xiao Yan rolled over and got up from the ground, his face full of excitement.

"But...... I have to ask your Danzun master's opinion first, after all, if you learn alchemy, you can't hide it from him!"

"The devil knows what he's doing, it's mysterious. I've seen her less than ten times in the past six months!" Xiao Yan complained.

In the past half a year, Nalan Yanran threw Xiao Yan this torture task, but she was not idle, she went back to the Yunlan Sect, got the sect master token and entered the Tibetan Scripture Pavilion, and scanned all the classics of the entire Yunlan Sect and exchanged them for points, and her own cultivation has also improved too much.

The most important point is that in the past half a year, Nalan Yanran found an opportunity to go to the Tagar Desert.

According to the system, there is a strange fire in the Great Desert of Tagger.

Strange fire, that is the existence that can be exchanged for sky-high points. Moreover, Nalan Yanran is now an alchemist, and she is also indispensable to strange fire. Every time I rent a different fire from the system, it is really not cost-effective, so Nalan Yanran hopes that she can get the different fire in the Tagger Desert, if you can refine it, it is naturally the best, if not, exchange the different fire to the system, exchange for points, and then buy a wisp of different fire seed refining, it is also excellent.
