Mortal blood!

Lin Fan was shocked.

This matter was related to the secrets of the ancient true immortal world, so Lin Fan didn't dare to think too much.

He didn't dare to guess.

Soon, he suppressed the shock deep in his heart and quickly calmed down.

"Fairy, are you here to give me the elixir for refining immortal pills?"

Lin Fan looked at Cui'er curiously.

"That's right! Fellow Daoist Lin, these are some basic books on refining immortal pills that the young lady asked me to bring you, and some elixir."

"These things don't seem to be worth much to the young lady. But in other places, the value of just a silver thread grass would cost hundreds of low-grade immortal stones. Fellow Daoist Lin, the young lady values ​​you so much, don't let her down."

Cui'er chuckled and handed a storage ring to Lin Fan.

Lin Fan thanked him, took the storage ring and scanned it quickly.

He found that the alchemy books in the storage ring were piled up like a mountain.

Among them, there were also many natural treasures for refining immortal pills.

They were all things that Lin Fan had never seen before.

Moreover, each of the natural treasures exudes a strong power of rules. It seems quite powerful.

"It is exactly the same as what Fairy Xueling said. To refine immortal pills in the True Immortal Realm, you need to fight against the power of rules."

Lin Fan smiled bitterly.

At this moment, Cui'er flipped her palm and took out another small tripod and handed it to Lin Fan.

"This is the Black Flame Divine Cauldron that the young lady used when she learned to refine pills in her early years. It is a pill furnace commonly used by apprentice alchemists."

"Don't look at it as just a primary alchemy furnace, but it has 18,000 prohibitions. There are also various extremely rare water-attributed formations and power of rules. The total value is no less than 30,000 immortal stones."

"The young lady said that if you want to try to refine immortal pills, you can use the Black Flame Divine Cauldron."

Lin Fan's eyes lit up when he heard this.

When he saw the natural treasures for refining immortal pills just now, he realized that the alchemy furnace he used in the spiritual world could not refine immortal pills at all.

After all, the power of rules in the natural treasures needed to refine immortal pills is very strong.

Lin Fan wanted to reorganize the power of rules in these natural treasures, and ordinary alchemy furnaces could not withstand the impact of the power of rules.

What surprised Lin Fan was that Fairy Xueling was very thoughtful.

Not only did Cui'er bring the classics and natural treasures for refining immortal pills, but she also brought a black flame cauldron that could be used to refine immortal pills.

"Thank you, fairy, thank you, fairy Xueling."

Lin Fan smiled gratefully and took the black flame cauldron.

Seeing this, Cui'er did not stay for too long.

Soon, she said goodbye and left.

Seeing this, Lin Fan put away everything.

After opening the protective formation in the courtyard, he arranged several sets of formations that he carried with him, and then walked into the secret room for cultivation.

Using his clear and bright eyes, Lin Fan checked the secret room for cultivation inside and out. After confirming that there was nothing abnormal, Lin Fan took out the Lingmiao Immortal Map and entered it directly.

Wow!

The extremely pure spiritual energy of heaven and earth rushed towards him at a rapid speed.

If it were before, Lin Fan would definitely feel very comfortable.

But at this time, Lin Fan, who had already ascended to the True Immortal Realm and experienced the infinite benefits brought to him by the pure immortal energy, naturally looked down on these extremely rich spiritual energy of heaven and earth.

With a quick glance, Lin Fan was surprised to find that during the time when he had not entered the Lingmiao Immortal Picture, the iron-eating ants had actually reproduced several generations on their own.

Now, the number of iron-eating ants living in the Lingmiao Immortal Picture is as high as one million.

Such a large group of iron-eating ants, in order to compete for cultivation resources, began to split into several factions and began to fight.

In the Lingmiao Immortal Picture, the blood flowed like a river and the sky was dark.

Soon, the bodies of the defeated became the blood food of the victors.

As the number of iron-eating ants continued to decrease, the aura of the surviving iron-eating ants became stronger and stronger.

Especially the iron-eating ant king, there was a faint sign of advancing to the late stage of the tribulation.

In addition to the Iron-Eating Ant King, there were more than a dozen Iron-Eating Ants in the early stage of the Tribulation.

This made Lin Fan overjoyed.

"Although the Iron-Eating Ants are very powerful and eat everything, in the True Immortal Realm, the Iron-Eating Ants of lower realms, no matter how many there are, cannot play a role in the battle."

"Only these Iron-Eating Ants in the Tribulation Stage can help me in the battle."

"It seems that after the battle of the Iron-Eating Ants, there should be many Iron-Eating Ants that can be promoted to the Tribulation Stage, right?"

Thinking of this, Lin Fan was inexplicably happy.

With a wave of his hand, the Sweet Spring Dew that he had accumulated in the past few days was directly fed to the victorious Iron-Eating Ants.

Soon, the Iron-Eating Ants rushed forward frantically and devoured the Sweet Spring Dew in a moment.

Lin Fan smiled slightly and ignored the Iron-Eating Ants.

He looked at the Soldier Beans planted near the Sky Eagle Divine Tree.

I saw that there were an acre of Soldier Beans, and many of them had begun to wither.

The pale golden beans were hiding in the pods, waiting for Lin Fan to pick them.

"I haven't been to Lingmiao Xiantu these days, but the beans are growing well. Almost all the beans on this acre are ripe. If we harvest them all, there will be at least 20,000 or 30,000 beans, right?"

Lin Fan was overjoyed when he thought of this.

With a wave of his hand, a breeze blew across the pods.

He collected the ripe beans one by one.

Soon, a small group of them piled up in front of Lin Fan.

"Twenty-three thousand and one hundred soldier beans! Although my magic of scattering beans into soldiers can only turn these soldier beans into golden armored warriors of the Mahayana period. But with the advantage of numbers, they do have a certain attack power."

Lin Fan smiled with satisfaction and put away all the soldier beans.

After activating the Five Elements Destiny Sword and opening up a large piece of wasteland, and planting a large number of soldier beans again, Lin Fan took out all the books on refining immortal pills that Fairy Xueling gave him.

Wow!

A pile of books on refining immortal pills were piled up in front of Lin Fan.

There were hundreds of thousands of books.

Moreover, each book was written in the extremely rare golden seal script in the True Immortal Realm.

It was obscure and difficult to read.

If it were another cultivator, I'm afraid they would give up directly after seeing these golden seal scripts.

Fortunately, Lin Fan had learned golden seal script from the Book Soul, so now he had no problem reading these books on refining immortal pills.

Even so, it was still very difficult for Lin Fan to comprehend all the classics on refining immortal pills thoroughly, or even to the point of being able to recite them by heart.

"It would probably take hundreds or even thousands of years to digest all these alchemy classics."

"Even if the lifespan of a true immortal is infinite, how many true immortals are willing to spend so much time studying these things?"

Lin Fan smiled faintly.

The next moment, he moved his mind and came to the Taixu Spiritual Realm.

After filling a large amount of immortal stones in the formation slot of Area C, he began to meditate and comprehend.

As the classics on refining immortal pills were moved from the left to the right by Lin Fan, Lin Fan's understanding of refining immortal pills also became deeper.

But he was still not busy refining immortal pills.

Instead, he carefully integrated the alchemy classics he had read.

In a flash, Lin Fan stayed in the Taixu Spiritual Realm for more than 500 years, and Lin Fan finally finished reading all the classics.

Moreover, he had reached a preliminary level of mastery.

At this moment, many doubts about refining the elixir that had troubled Lin Fan were completely understood by Lin Fan himself.

In addition to Lin Fan's foundation in refining elixirs in the lower plane, Lin Fan felt that refining the elixir was not as difficult as Fairy Xueling said.

Thinking of this, Lin Fan couldn't wait to put away all the alchemy books.

With a flash of his figure, he went directly into the alchemy secret room, intending to try to refine the elixir for the first time.
