Mortal blood!

When Lin Fan appeared again, he was already in the cave.

At this moment, Lan Lan is already waiting in the living room.

Seeing Lin Fan coming out, she frowned slightly and said, "Husband, waiting outside the cave right now is Hua Yinglong from the Dark Immortal Royal Clan. Is he here to see the Dark Immortal Insect Mother Fairy?"

Lin Fan looked at Lan Lan and shook his head.

"Lan'er, you really think of him too simply."

Seeing Lan Lan's puzzled expression, Lin Fan smiled and explained: "Lan'er, he is the fourth prince of the Dark Immortal Royal Family. Isn't it easy for him to find out our identities?"

"This...he is here to find us?"

"Isn't it?"

Lin Fan smiled and nodded.

Soon, Lin Fan waved his hand, and the protective formation outside the cave was quickly closed.

Not long after, Lin Fan and Lan Lan arrived outside the cave.

Hua Yinglong, who was waiting outside, laughed when he saw this.

"Master Lin, you and your wife do indeed live here. I only found out after asking a lot of questions that you and the Dark Fairy Insect Mother are old friends." Hua Yinglong said with a smile.

"We are just the attendants of the Dark Fairy Insect Mother." Lin Fan said with a smile.

While talking, he invited Hua Yinglong into the cave.

After everyone sat down, Lin Fan flipped through it and took out a pot of fairy brew. After pouring a cup for Hua Yinglong, Hua Yinglong couldn't help but look overjoyed.

"Master Lin, the aroma of your fairy wine is very mellow. It is not ordinary at first glance. If I guessed correctly, this seems to be the extremely rare Zuixia fairy wine, right?"

"Fellow Taoist, you really have a good eye. This is a fine wine that I have treasured for a long time. It is the Zuixia Immortal Brew." Lin Fan said with a smile.

"Haha, if that's the case, I'll have to ask for an extra drink!"

Hua Yinglong looked overjoyed.

Just waiting for him and Lin Fan to have a happy chat.

Lin Fanming knew that Hua Yinglong came here this time to ask him to refine the Great Qianyuan Pill.

But at this time, Hua Yinglong didn't mention anything, and Lin Fan wasn't in a hurry.

After the pot of Zui Xia Xian Brew was drunk, Hua Yinglong finally got down to business.

"Master Lin, I came to you this time with the materials for refining the Great Qian Yuan Dan."

Having said this, Hua Yinglong immediately turned his palm, and a storage ring and a jade slip quickly appeared in his palm.

Then, these two things were delivered to Lin Fan.

"Fellow Daoist Lin, please take a look."

"Um!"

Lin Fan nodded.

He first picked up the jade slip and examined it carefully for a while, and after confirming that it was the recipe for the Great Qianyuan Pill, he immediately smiled with satisfaction.

"There is nothing wrong with this elixir. It is indeed the Great Qianyuan elixir."

Afterwards, Lin Fan put the storage ring away without even looking at it.

This made Hua Yulong smile with satisfaction.

"Haha, if that's the case, I'll leave it to Master Lin to refine the Great Qian Yuan Pill. I wonder how long it will take Master Lin to refine the Great Qian Yuan Pill?"

When Hua Yinglong said this, he couldn't help but look expectant.

Lin Fan did not reply immediately.

After pondering for a long time, he said: "Refining the Great Qian Yuan Pill is not an easy task. Even if I am now an eighth-level alchemist, it will take several months to successfully refine the Great Qian Yuan Pill. Time. How about friendship?"

"How many months? Master Lin, are you sure?"

"Haha. I am an alchemist, and my time has been carefully calculated. Naturally, there will be no mistakes."

Lin Fan smiled lightly.

As long as he is willing, he can refine the Great Qianyuan Pill in minutes.

However, the reason why Lin Fan said this was to let Hua Yinglong understand how difficult it is to refine the Great Qianyuan Pill.

It is convenient for Hua Yinglong to owe him a favor.

To Lin Fan's surprise, Hua Yinglong's answer surprised Lin Fan.

"Master Lin, you are worthy of being an eighth-grade alchemist. To be honest, you are the most cheerful person among the alchemists I have ever come into contact with. Okay, as long as you refine the Great Qianyuan Pill, you can notify me at any time. "

"I won't bother you, Master Lin. If you encounter any trouble in the Dark Immortal King City in the future, you can always come to me. Farewell!"

Hua Yinglong looked overjoyed.

After thanking him, he left immediately.

After sending Hua Yinglong away, Lin Fan did not directly enter the alchemist in the alchemy chamber.

Instead, he took out Hua Yinglong's storage ring and inspected it carefully.

After confirming that no manipulation had been done to Hua Yinglong's storage ring, he secretly breathed a sigh of relief.

"Husband, don't you believe Hua Yinglong?"

Lan Lan asked curiously.

Lin Fan smiled and nodded.

"Lan'er, you and I have already experienced how dangerous the real immortal world is. No matter who it is, we shouldn't completely trust him."

"Don't look at Hua Yinglong asking for help from me now. It seems that he should go all out to cooperate with me in refining the Great Qianyuan Pill. But no one can guarantee that he has no other thoughts."

"There's no harm in us being more thoughtful."

Seeing Lin Fan's solemn expression, Lin Fan smiled again and said, "But don't worry, Lan'er. Before I refined the Great Qianyuan Pill, even if Hua Yinglong had other thoughts, he would not treat us badly." Hands-on."

"Good husband."

Lan Lan agreed with a smile, and when he was about to return to his secret room to practice, he was grabbed by Lin Fan.

"Husband, you..."

Looking at Lin Fan's smiling expression, Lan Lan blushed instantly.

As someone who had been there, she didn't know what Lin Fan meant.

Soon, with Lan Lan half pushing and half giving, the two of them were engaged in a passionate fight.

…

A few days later, Lin Fan and Lan Lan entered the state of seclusion and practice again.

However, Lin Fan, who returned to the secret room, was not idle at this moment.

After entering the Taixu Spirit Realm directly, he began to take out the recipe of Daqian Yuandan and seriously comprehend it.

The whole process took more than 20 years.

When Lin Fan completely understood every detail of refining Daqian Yuandan, he did not start to refine the pill.

Instead, he took this opportunity to sort out the details of refining Daqian Yuandan in detail.

To ensure that there is no mistake.

In this way, after several years, when Lin Fan felt that he had 70% confidence and could refine Daqian Yuandan in one go, he finally started.

Huh!

Taixuan Medicine Cauldron was quickly activated by Lin Fan.

Not long after, a ball of hot flames emerged under Taixuan Medicine Cauldron.

The extremely pure power of fire attribute rules continued to heat the bottom of Taixuan Medicine Cauldron.

In just a moment, the temperature in Taixuan Medicine Cauldron increased a lot.

Seeing this, Lin Fan was not anxious.

His mind was completely focused on the Taixuan Medicine Cauldron.

After confirming that the temperature in the Taixuan Medicine Cauldron had reached the optimal temperature for refining the Daqian Yuandan, he threw a prepared immortal medicine directly into the Taixuan Medicine Cauldron.

Boom!

The scorching high temperature in the Taixuan Medicine Cauldron instantly burned the immortal medicine into ashes.

Only a drop of crystal clear medicinal essence fell rapidly to the bottom of the Taixuan Medicine Cauldron.

And it kept spinning in the boiling cauldron.

The rule power in the medicinal essence was also completely decomposed at this moment.

Lin Fan took this opportunity to keep the required rule power and completely melt the unnecessary rule power.

After waiting for these things to be done to the extreme, Lin Fan threw another immortal medicine into the Taixuan Medicine Cauldron.

...

Lin Fan's alchemy steps were orderly.

Each step was very refined.

Even so, the process of refining the Daqian Yuandan was not very smooth.

Especially when various rules began to blend and form the immortal pill, several extremely powerful rules in the Taixuan Medicine Cauldron collided with each other.

All of a sudden, the Taixuan Medicine Cauldron trembled violently.

If Lin Fan hadn't reacted quickly and tried his best to stabilize the Taixuan Medicine Cauldron, I'm afraid the Taixuan Medicine Cauldron would have been in danger of exploding.

Fortunately, the final result made Lin Fan very satisfied.

After this series of careful preparations, the Daqian Yuandan was finally successfully refined by Lin Fan.

Buzz!

The lid of the cauldron was opened, and round and smooth immortal pills shot out of the cauldron.

Looking at the immortal pill with eight dan patterns on the surface, Lin Fan was overjoyed.

"Eight-turn immortal pill, Daqian Yuandan. I really refined it."

"However, since this thing is useful for Hua Yingwu to impact the immortal saint realm, it should also be useful for the ancestor and Elder Qin Wushuang to impact the immortal saint realm?"

Thinking of this, Lin Fan was overjoyed.

Anyway, there are still a lot of immortal medicines in the storage ring that Hua Yinglong gave him.

Lin Fan roughly calculated that the immortal medicines that Hua Yinglong prepared for him were enough for him to refine five furnaces of Daqian Yuandan.

Even though he was so rich, Hua Yinglong did not dare to ask ordinary alchemists for help.

This is enough to show the preciousness of these immortal medicines, and the success rate of other alchemists in refining pills is definitely not as high as Lin Fan.

However, these things have nothing to do with Lin Fan.

Anyway, he has successfully refined a furnace of Daqian Yuandan, although the quality is only inferior.

But there is no problem in using it to hand over to Hua Yinglong.

However, Lin Fan does not intend to hand over the Daqian Yuandan so easily.

With a thought, he made some other moves in the Daqian Yuandan, and then smiled slightly.

"Haha, in this way, others can only see that the residual fire attribute rule power in these pills is more concentrated. But there will be no other objections, right?"

Lin Fan smiled faintly.

Satisfied, he put away the Daqian Yuandan along the way.

Next, Lin Fan began to refine two more furnaces of Daqian Yuandan.

One furnace was given to Lin Xiandi, and the other furnace was given to Qin Wushuang.

As for Daoxuanzi, his realm was temporarily equal to Lin Fan, and Daoxuanzi did not need things like Daqian Yuandan. Lin Fan could only put away the remaining medicinal materials and leave them for himself.

Nothing was said for a while, and he waited for Lin Fan to finish the things at hand, and then began to practice again.

However, now he did not continue to refine the body-building medicinal stones.

Instead, he seriously comprehended the Tianque Gold Page and Tianque Silver Page.

With those Tianque Gold Page and Tianque Silver Page connected together, Lin Fan did not dare to be careless about the comprehension of this relatively complete content.

But he also knew very well that it was very difficult to comprehend the Tianque Gold Page and Tianque Silver Page.

It was impossible for him to fully understand it.

Taking advantage of this time, comprehending 70% or 80% would be a great gain.

...

In a flash, Lin Fan, who was in the Taixu Spiritual Realm, had spent tens of thousands of years.

Thinking about the outside world, after a long time, Lin Fan had no intention of continuing to practice.

With a thought, he took out the jade talisman that Hua Yinglong left for him, and activated it on the spot after saying a few words.

After just a meal, Hua Yinglong appeared outside Lin Fan's cave.

Seeing this, Lin Fan left the Taixu Spiritual Realm and invited Hua Yinglong in.

This time, Lin Fan didn't need to speak at all.

Hua Yinglong happily took out the Huanxian Grass promised to Lin Fan.

"Master Lin, this is the Huanxian Grass you need, please take a look."
