Mortal blood!

"Oh?"

Xue Ling looked surprised.

Seeing Lin Fan's serious expression, she smiled and said, "I still don't know your name."

"Reporting, fairy, my name is Lin Fan!"

"So it's Fellow Daoist Lin!"

Xue Ling nodded.

Soon, she smiled and said, "Fellow Daoist Lin, if you have any questions, just ask."

"Yes. When I was in the lower plane, I also refined pills. But I still don't understand the matter of refining immortal pills in the True Immortal Realm. Why do the pills refined in the True Immortal Realm need to be tried by medicine slaves?"

Lin Fan looked puzzled.

Seeing this, Xue Ling smiled.

"Fellow Daoist Lin, although you are an alchemist from the lower plane, you must be proficient in pharmacology, right? The elixirs we need for cultivation cannot all be purified to 100%."

"Especially the spiritual medicines used to refine immortal pills, each of which is an extremely rare treasure from heaven and earth."

"For an alchemist, it takes a long time to purify them all."

"It is better to use these unpurified treasures to refine immortal pills directly."

"In this way, the medicinal power of immortal pills refined with impure treasures will also be greatly different."

"Even if each immortal pill is refined strictly according to the recipe, because each alchemist has different alchemy techniques, behavioral habits, etc., the efficacy of the refined medicines is also very different."

"So, we need a large number of medicine slaves to test the medicine."

Speaking of this, Xueling paused slightly.

Looking at Lin Fan with a serious look.

"Fellow Daoist Lin, you may not know that the medicine slaves who test medicine need extremely strong bodies. If they are not careful, the newly refined pills will break through their bodies."

"The medicine slaves who came with you have been impacted by the medicinal power of the immortal pills because of long-term drug testing. They are beginning to rot."

"It won't be long before these medicine slaves whose bodies begin to rot will die."

"So, these people don't cherish anything. They just want to live one day at a time."

Xue Ling's words shocked Lin Fan.

He didn't expect that refining immortal pills in the True Immortal Realm would be so risky.

What's more, his role here with Xue Ling is the most dangerous medicine slave.

This made Lin Fan's heart sink suddenly.

"Although I am practicing both the Dharma and the body. But I can't guarantee that my body can withstand the impact of the medicinal power of the immortal pill every time."

"It seems that I have to think of a permanent solution."

Thinking of this, Lin Fan looked at Xue Ling with curiosity again.

"Thank you for telling me the truth, Fairy. I have another question. Is there no alchemist in the True Immortal Realm who can completely purify all the natural treasures?"

"This..."

Xue Ling was slightly stunned.

She looked at Lin Fan as if he were a monster.

After a long silence, Xue Ling nodded seriously.

"Of course. That is something that only the Lord Dan Emperor can do. In fact, it does not need to be completely purified. It is only necessary to purify the medicinal power of each spiritual medicine to 70%. Even without medicine slaves, the quality of the pill can be guaranteed."

"It's a pity that the most difficult thing when refining immortal pills is to purify the medicinal power. Don't look at me now. I am already in the realm of human immortals. But I still can't even refine the third-level immortal pill. I can't become a third-level alchemist until now."

When Xue Ling said this, there was a hint of loss in her beautiful eyes.

Seeing this, Lin Fan's eyes lit up.

"Fairy, do you have any remaining spiritual medicines for refining pills? Can you give me some less expensive spiritual medicines so that I can try to purify them?" Lin Fan said.

"Haha, Fellow Daoist Lin, I advise you not to waste your efforts."

"Fellow Daoist is only in the late stage of transcending tribulation, and there is still a big realm away from the realm of human immortals."

"Fellow Daoist may not know that the natural treasures in the real immortal world also contain extremely powerful rule power."

"Purifying natural treasures is to fight against the power of rules. Only the higher the realm, the higher the level of purification."

"Fellow Daoist Lin, do you understand what I mean?"

Although Xueling's words were very simple.

But Lin Fan was still unwilling.

After a moment of silence, Lin Fan said with a stiff face: "Fairy, everything cannot be generalized. What if I succeed?"

"It's up to you. Anyway, I don't lack spiritual medicines for refining immortal pills. Wait a minute, I'll let Cui'er send you some."

Xueling nodded.

Soon, she waved her hand and a palm-sized jade token was thrown to Lin Fan by her opponent.

"This is the control token for the formation you enter and exit my mansion. Don't lose it. In addition, you will live in my mansion in the future. Be at my disposal at any time. Let's go!"

Xueling said, and immediately turned and walked forward.

Seeing this, Lin Fan did not hesitate.

He took the token in his hand and secretly scanned it with his clear and bright eyes. He saw that there were several very powerful rule powers in this token.

When he saw that it was much purer than the rules of the human immortal pattern he got in the lower plane, Lin Fan was immediately surprised.

"For others, this token seems to be just a token to open the formation. But for me, it is a good thing to comprehend the power of rules."

"It seems that there are treasures everywhere in the True Immortal Realm. It is indeed an excellent place for cultivation."

Lin Fan was secretly ecstatic.

After following Xueling to the mansion where she lived, Lin Fan was completely dumbfounded.

Just see!

On the hillside of Shenzha Immortal Mountain, there is a loft suspended in the air, shrouded by colorful lights.

It emits a holy light.

From a distance, it looks like a pearl hanging in the misty Shenzha Immortal Mountain, which is eye-catching.

Before Lin Fan entered Xueling's mansion, a pure and incomparable fairy air came to his face.

Lin Fan's realm was instantly improved a lot at this moment.

"It is indeed the immortal mansion. Practicing in such a place can definitely achieve twice the result with half the effort."

"It's a pity that I haven't entered the immortal pool yet. Some of the spiritual power in my body still can't be converted into immortal power."

"Even if I refine too much fairy energy, my realm can't reach the realm of true immortals. This is really a pity."

Lin Fan muttered secretly.

After taking out the token, he followed Xueling into the mansion.

Soon, Lin Fan saw Cui'er, whom he met last time.

At this moment, she was welcoming Xueling back with a group of beautiful maids.

"Cui'er, take your fellow Taoist and find him a small courtyard to live alone. Tell him the rules here, so that he won't be ignorant of etiquette and make mistakes."

"In addition, fellow Taoist Lin is also an alchemist. Wait, take some spiritual medicines and some books on refining immortal pills from me and give them to fellow Taoist Lin."

After Xueling gave the order, she left immediately.

Lin Fan was left alone.

Seeing this, Cui'er, who saw Xueling off, cast a look of surprise at Lin Fan.

"You are also an alchemist? Why...why didn't you say so earlier?"
