The bait has been dropped, and as for when the fish will take the bait, it has nothing to do with Lu Xuan.

He returned to the cave and patted the fat bird's round belly, the flesh was surging, soft and comfortable, and it felt very good.

When he came to the spiritual field, he inspected all the spiritual plants, and if he found any spiritual plants with the slightest need, he would try his best to meet them.

In the end, half of the spiritual power in his body was consumed, and he returned to the small courtyard.

After a short period of recuperation, enter a nearby Dan room.

Due to the fact that a lot of Danfang experience packs were opened from the light group, Lu Xuan Dandao made rapid progress, and he had a small success and even a grandmaster realm level in certain pills.

He took out the Tibetan Yuan Grass that had been stored before, and his spiritual power carefully divided and peeled off the leaves, and in the end, only a rich and pure spiritual qi mass was left.

Immediately afterwards, the processed Tibetan Yuan Grass was added with other materials, and according to the records on the Danfang, they were fused with great skill.

Under the Dan furnace, a light blue flame suddenly lit up, extending rapidly, burning quietly.

The light blue flame is the four-grade azure pill fire, which is said to come from the alchemy sect Tushi Sect, which is a kind of fire that is extremely suitable for refining pills, which can slightly improve the rate of becoming a pill and the quality of the pill.

According to the order, Lu Xuan put the processed various materials and solvents into the Dan furnace.

He didn't have a lot of experience in refining Zhuji Dan, but because he had absorbed a large number of Dan experience packs, Zhuji Dan's refining level was in the period from small to large completion, which was much stronger than most of the Dan masters in the Heavenly Sword Sect's Dan Palace.

Half an hour later, his spiritual sense was keenly aware of the changes in the Dan Furnace, and with a movement of his mind, the top lid of the Dan Furnace was lifted, and four pills the size of a dragon's eye shot out like lightning.

Lu Xuan's spiritual power stopped the four pills, stretched out his palm, and the four Zhuji pills lay quietly in the palm of his hand.

There are many spirit patterns swimming on the surface of the pill, and the faint light shines out, which makes people feel refreshed when they smell it.

"Four Tsukidans in one furnace, not bad."

Lu Xuan said secretly in his heart.

"In the future, the main source of spirit stones will depend on alchemy."

Although there are many treasures on his body, the five-grade treasures are not easy to sell with his current foundation realm.

Only by finding a reputable force and disguising your identity can you have a chance to exchange for something else.

As for the third-grade and fourth-grade treasures, he has successively produced a lot of them, which are used to obtain high-level spirit seeds, or demon beast flesh and blood, and so on.

The largest number in his hand is the four-grade sword talisman, which is extremely useful for him at present, so he plans to keep it on his body.

He now has a success rate of about six or seven percent in refining Zhuji Dan, and the alchemist has a success rate of about thirty percent in a certain pill, so he can basically break even, and if he is six or seven percent, it will be a sure profit.

"With this probability, every time you refine a furnace of Zhuji Dan, you can earn thousands of spirit stones."

"If it is raised to the realm of Dacheng or even the Grandmaster, that furnace can earn more than 10,000 or even 20,000 lower grade spirit stones."

Lu Xuan sighed, feeling at the ability of the grandmaster-level Dan Master to absorb gold.

Thinking of this, he was full of motivation and continued to open the furnace for alchemy.

He refined ten furnaces in a row, and only stopped when he felt a little tired.

Ten furnaces of pills, of which seven were successful, ranging from three or four Tsukidan to each furnace, a total of twenty-six Tsukidans were obtained.

"Barely a Dan Dao master."

Lu Xuan showed a hint of a smile and put Tsukidan into the storage bag.

Suddenly, there was a slight strange sensation on the back of his hand, as if there was a continuous flow of water.

Under his spiritual sense, he noticed that the medicine pig that had been living in the Dan room came over at some point.

"Have you eaten a full dose of erysipelas today?"

Lu Xuan's mind condensed on the translucent, unfixed form medicine pig, feeling the joy it transmitted, and laughed softly.

This medicine likes to eat the erysipelas contained in the pill furnace and pill, and if it fails to build the foundation of the three furnaces, it will definitely let it have a big meal.

"Huh? Is this about to break through? ”

Suddenly, the aura on the body of the medicine pig lying on the back of his hand gradually became stronger, and his body was slowly revealed.

There was a faint medicinal fragrance from the Dan room, and the aroma flowed, slowly gathering around the medicine pig, forming a wisp of strange smoke and integrating into the medicine pig's body.

The smoke accumulates more and more, and finally envelops the medicine pig.

After a while, an inaudible sound sounded, a slight crack appeared on the strange smoke hood, and in Lu Xuan's spiritual sense, a medicine pig that was more than twice as large as the size flew out of it and landed on his shoulder as if nothing was there.

His mind was condensed on the body of the medicine pig, and suddenly, a thought appeared in his mind.

[Medicine pig, four kinds of insects, almost invisible and colorless, afraid of contact with living beings, like to eat the pillas left in the Dan furnace and pills, parasitic in the Dan furnace, can automatically clean and maintain the Dan furnace, ensure the quality of the Dan furnace, and slightly improve the quality of the Dan medicine. 】

"I have finally grown to the fourth grade, and it is in vain that I usually use so many fourth-grade or even fifth-grade pills to raise you."

Lu Xuan was full of emotion, the pills he prescribed from the light cluster had to pass through the hands of the medicine pig, providing it with nutrients and letting it clean up the possible residual erysipelas by the way.

The Four-Rank Xuanyin Pill, the Lust Pill, the Cleansing Pill, and the recent Tuyuan Pill, and even the Five-Rank Holy Infant Pill that he got earlier, in addition, he usually has the habit of alchemy, and under various factors, the growth rate of the medicine is extremely fast.

"I don't know what kind of light group reward this rare four-grade insect can offer."

Lu Xuan calmed the medicine pig who had successfully broken through, and his attention was attracted by the white light cluster that was quietly floating in the air.

With anticipation, reach out and gently touch the surface of the light cluster.

The light cluster exploded silently, turning into countless tiny points of light, condensing into a phantom of an ancient book, and submerged into Lu Xuan's body.

A thought crossed my mind.

[Yaozhi was promoted to the fourth grade and harvested the "Seven Chapters of the Pharmacist" (I). 】

An ancient mottled book appeared in front of Lu Xuan.

He opened it cautiously, and the page of the book recorded the detailed information of a four-grade spiritual plant, the corresponding handling tips, specific medicinal properties, and which elixirs were compatible or conflicting.

Flipping back, you can still see the introduction of many pills, but unfortunately there are no specific pills.

["Seven Chapters of the Pharmacist", a treasure without grade, according to legend, it is a Dan Dao classic written by an elder of the Tushi Sect who is good at alchemy based on his life experience, recording the medicinal properties of many spiritual plants in the world, which is invaluable to alchemists. 】

[In the later chapters, there are also several records of the five and six Dan prescriptions deduced by it, which need to be verified.] 】

"The writings of the Yuan Ying Elder-level Dan Master? If you get the so-called Tushi Sect, I don't know what you can get. ”

When he learned that the treasure was of no grade, Lu Xuan first felt a chill in his heart, and only after understanding the information of the ancient books in detail did he feel a lot more relieved.

"The next few chapters also record the Danfang deduced by Yuanying Zhenjun?"

He couldn't wait to turn to the end.

"Huh? Where did the next few chapters go? ”

"What a broken dog!"

He couldn't help but curse.

(End of chapter)
