There was a secluded room in the depths of the attic, which was Lin Nan's carefully arranged alchemy room.

Refining pills is quite similar to cultivation, if it is disturbed by the outside world, the pill will be destroyed at the least, and even the person who refines the pill will be counterattacked.

At this moment, Chu Ruirui was taking out a bottle of medicine tripod from the Qiankun bag, only to see that the medicine tripod was completely black, and four hideous little snakes were inlaid with the ring, which was lifelike.

"In addition to alchemy's own Taoism, the medicine tripod is also very important, and it has an auxiliary effect on the alchemy. The Snake Ding is ranked ninety-three in the Hundred Ding List. Chu Ruirui pointed to the smug words of the medicine tripod in front of her.

Lin Nan looked at the medicine tripod, his eyes flashed with envy, this tripod knew that it was extraordinary at a glance.

"Stunned, hurry up and bring the medicinal herbs. Chu Ruirui reprimanded unhappily.

Lin Nan let out an "oh" and hurriedly spread the medicinal materials collected during this period in front of the other party.

Chu Ruirui's eyes swept over, and her red lips squirmed slightly, "Lotus heart grass, lily ginseng, black grapes, licorice..."

"What elixir do you want to refine?" Chu Ruirui asked with a slight frown.

"Cleansing the myelin. ”

Lin Nan opened the "Dan Dao", and at the end of the book, there were several prescriptions, one of which recorded the 'Washing Pill'. The pill has the effect of activating the meridians, and it is a rare elixir for monks who are in the period of qi training.

Chu Ruirui shook her head and said, "No, no." The Purifying Pill is a first-class elixir, and your medicinal material still lacks the demon core of a first-order demon beast. ”

She turned to look at Gu Yu and said, "Otherwise, if you slaughter this stupid eagle, it would be more than enough to refine the marrow cleansing pill with its demon core." ”

"Quack, quack. Gu Yu roared in dissatisfaction.

Chu Ruirui covered her mouth and smiled, and said, "How, how are you thinking about it?"

Lin Nan pursed his lips and flipped through the ancient books, only the prescriptions recorded in this book are the first-grade pills, and the rest are all prescriptions for healing injuries and qi training, and it is not much of a problem for him to refine these, not to mention Chu Ruirui.

With an idea, Lin Nan waved his hand and said, "That's it, that's it, I guess you know that the refining of the marrow cleansing pill is difficult, there are still a few prescriptions here, you can pick up an easy one to refine!"

After speaking, Lin Nan handed the ancient book to Chu Ruirui, and he walked to the side and sat down with his cheeks.

Chu Ruirui is angry and brainy, what kind of attitude does this guy have. She scolded viciously: "Miss Yin thief Ben has no problem refining the second-grade pill, can it be rare for me to wash the marrow pill?"

"I didn't say that you can't refine the Purifying Pill, it's just that the materials are insufficient now, so you can just refine one casually. Lin Nan narrowed his eyes, looking lazy.

Chu Ruirui snorted: "The agitation method has no effect on Miss Ben. ”

Lin Nan pouted and spread his hands.

Looking at his appearance, Chu Ruirui gritted her teeth with hatred, and said angrily: "Okay, good." Miss Ben will let you see what alchemy is. In the future, don't take out your carving insect skills to be embarrassed. She decided to refine the Purifying Pill and hit this thief hard.

Lin Nan smiled evilly in his heart, and shrugged his shoulders meaninglessly.

Chu Ruirui gritted her silver teeth, then turned around and slowly closed her eyes. When she opened it, the jade hand then pinched out a complex knot.

"From. She snorted softly, and a light cyan flame suddenly flashed out, and under her control, all of them burrowed into the Stygian Serpent.

"The first step in alchemy is to heat the furnace, and the temperature of the medicine pod needs to be calcined and balanced. Chu Ruirui seemed to have the intention to remind Lin Nan and said to herself.

In a quarter of an hour, when the Dark Snake Ding was slightly steaming, Chu Ruirui grabbed the lotus heart grass and threw it into the medicine tripod. Then she summoned her true qi, and the pale cyan flames burned like raging dragons.

After a while, when Chu Ruirui unveiled the medicine tripod, the lotus heart grass had already refined a bunch of powder. Next, she did the same, refining the medicinal herbs on the table one by one.

Some of these more than ten kinds of medicinal materials are calcined into powder, some are condensed into solids, and some are refined into liquids.

At this time, Chu Ruirui wiped the beads of sweat on her forehead and took a breath of air, "To refine medicinal materials, you must carefully control the heat, each medicinal material has a different surname, and the corresponding temperature is also completely different." ”

"What would happen if the heat was not well controlled?" Lin Nan asked.

Chu Ruirui glanced at Lin Nan and said, "If the heat is too high, the medicinal materials will be easily burned to ashes, and if the heat is too low, the medicinal materials will not be able to volatilize, and the rarer the medicinal materials, the more obvious the performance." Therefore, when alchemy monks refine high-grade pills, they will prepare a few medicinal materials in advance to prevent the failure of refining or the failure of condensing pills. ”

Lin Nan nodded suddenly.

Chu Ruirui then turned her head to look at the more than ten vials on the table, and said, "Next, the Ning Dan is the most important part of alchemy, and once it fails, all the medicinal materials refined will be in vain. ”

She took a fist-sized thing from the Qiankun bag, with some dark red colors similar to spars, and said, "This demon wolf's demon core is the most suitable for condensing medicinal herbs." First of all, it is necessary to refine the evil qi in the demon core, and then add medicinal materials one by one. ”

Chu Ruirui explained the rest of the steps roughly, and then concentrated on integrating into the alchemy.

The room was silent again, and from time to time there would be a slight sound of flames popping out of the medicine pod.

Since Chu Ruirui's alchemy, Lin Nan's eyes have never left the medicine ding. The former's skillful skills amazed him, and this little witch usually said that he didn't see her cultivating, and he couldn't imagine that his skills were not small.

As time passed, Chu Ruirui's expression became more and more solemn, and a trace of sweat seeped down her temples, and then the high temperature evaporated into nothingness, and her pure and beautiful face was reflected in the pale cyan flames. Lin Nan's heart suddenly appeared: she also has such a quiet and beautiful side. With a slightly pointed chin, a chic melon seed face and a faint flush under the flame, there is a faint elegance under the beautiful eyes.

Lin Nan was stunned.

After wisps of blood-red qi rose from the medicine tripod, Chu Ruirui added the medicinal materials that had been refined before to the medicine tripod one by one. Her face was solemn, her jade hand was handed over, and the invisible true qi was passed into the Ding Furnace and transformed into a pale cyan flame under her urging.

Time in the room seemed to pass unusually slowly, and I don't know how long later, a wisp of medicinal fragrance finally wafted out of the medicine ding.

As time passed, the fragrance of the medicine became more and more intense, and even Gu Yu, who had dozed off because of boredom before, stood up, his eyes rolling and staring at the medicine ding.

Suddenly, Chu Ruirui's eyes flashed, and she snorted: "Condensation." At the same time, the pale cyan flame of the Ding Furnace was also withdrawn by her.

As the sound fell, the lid flew out, and a cyan elixir shot out, caught in the middle of Chu Ruirui's onion-like jade fingers. She turned around, a smile flashed on her slightly flushed face, but it suddenly froze, and she turned her head to look in the direction of Yuntai Peak.
