Mortal blood!

Lin Fan did not hesitate, and with a thought, he came directly to the Taixu Spirit Realm.

After filling the Wu area with a large amount of low-grade immortal stones, Lin Fan took out the recipe of the Soul Feeding Immortal Pill again and studied it carefully.

In order to ensure that he could refine a higher quality Soul Feeding Immortal Pill, Lin Fan was very careful and did not dare to be careless.

Only after he thoroughly studied a recipe, Lin Fan took out the Black Flame Divine Cauldron and began to refine the pill.

Huh!

Pure flames emanated from the Black Flame Divine Cauldron.

At this moment, a pure and incomparable force of fire attribute rules slowly lingered at the bottom of the Black Flame Divine Cauldron.

The temperature in the Black Flame Divine Cauldron also gradually increased at this moment.

Lin Fan's divine thoughts and clear eyes were activated at the same time, closely observing the changes in the Black Flame Divine Cauldron.

After a while, only when the temperature in the Black Flame Divine Cauldron reached the standard for refining the Soul Feeding Immortal Pill, Lin Fan carefully threw the spiritual medicine needed to refine the Soul Feeding Immortal Pill into the Black Flame Divine Cauldron.

Soon, under Lin Fan's control, the immortal medicine was completely purified.

...

An hour later, a strong medicinal fragrance emanated from the Black Flame Divine Cauldron.

Lin Fan was safe and sound, but Lin Fan clearly felt that the Iron-Eating Ant King in the Lingmiao Immortal Picture seemed to have sensed the breath of the Soul-Feeding Immortal Pill.

He suddenly became extremely impatient.

He even kept asking Lin Fan to leave the Lingmiao Immortal Picture.

"Hehe, the immortal pill that even the Iron-Eating Ant King wanted so badly must be extraordinary. I just don't know how many turns of immortal pills I refined this time."

Lin Fan smiled slightly.

He pointed his finger in the air, and the lid of the Black Flame Divine Cauldron popped open.

The strong medicinal fragrance inside, accompanied by ten streams of light, shot out rapidly.

Seeing this, Lin Fan waved his hand skillfully and took the ten streams of light into his hand.

Soon, the light faded away and turned into ten longan-sized, round and smooth Soul-Feeding Pills that exuded a strong medicinal fragrance.

On it, three shallow lines appeared on the surface.

"Third-turn Soul-Feeding Pill? Judging from the quality, it is at least medium-grade. If I use the mysterious copper bottle to purify it, the quality of the third-turn Soul-Feeding Pill will be improved to a higher level."

"This is really an unexpected gain."

Lin Fan was extremely ecstatic.

As he spoke, he took out the mysterious copper bottle, threw the refined Soul-Feeding Pill into it, and then it was rapidly strengthened.

In just a moment, when all the strange phenomena disappeared completely, the Soul-Feeding Pill really changed from medium-grade to high-grade.

"High-grade Soul-Feeding Pill? This quality is not bad. Now, I will bring the Iron-Eating Ant King over and let it practice in the Taixu Spirit Realm."

As Lin Fan spoke, his mind moved.

Soon, the Iron-Eating Ant King appeared in front of Lin Fan.

Feeling the strong medicinal fragrance emanating from the Soul-Feeding Pill, the Iron-Eating Ant King suddenly looked ecstatic.

He kept baring his teeth at Lin Fan.

"Okay, don't act so fierce in front of me. These Soul-Feeding Pills are for you."

As Lin Fan spoke, he threw the Soul-Feeding Pill to the Iron-Eating Ant King.

The impatient Iron-Eating Ant King immediately pounced over with joy.

Soon, he swallowed a Soul-Feeding Pill into his stomach.

In just a moment, Lin Fan clearly felt that the Iron-Eating Ant King's realm had improved a lot.

"The effect of the Soul-Feeding Pill is really good. In this case, I will continue to refine the Soul-Feeding Pill here and let the Iron-Eating Ant King practice here."

Lin Fan muttered softly.

After giving the Iron-Eating Ant King a few more Soul-Feeding Pills, he asked the Iron-Eating Ant King to refine the medicinal power of the pills on the side.

And he himself began to refine the Soul-Feeding Pill again.

Although it is easy for Lin Fan to refine the third-level immortal pill now, Lin Fan knows very well that even if he refines more soul-feeding immortal pills, it will not be enough.

After all, the current iron-eating ant colony has reached a full one million.

However, what makes Lin Fan happy is that after reaching a million, the iron-eating ant colony began to split into several factions and kept fighting.

The corpses of companions were devoured by the victors.

It is precisely because of this that the overall realm of the iron-eating ant colony is also steadily improving.

But Lin Fan always feels that if the iron-eating ant colony is allowed to improve its realm on its own, it still cannot help him much in the battle.

Therefore, Lin Fan decided to refine the soul-feeding immortal pill and feed a batch of iron-eating ants accurately.

In a flash, more than half a year has passed.

The iron-eating ant king is still refining the soul-feeding immortal pill.

But Lin Fan has completely refined all the soul-feeding immortal pills.

Taking this opportunity, Lin Fan went to the Lingmiao Immortal Map.

He selected 10,000 iron-eating ants in the late stage of the tribulation and fed them with the Soul-Feeding Immortal Pill.

As a result, many of these iron-eating ants in the late stage of the tribulation could not withstand the power of the third-turn immortal pill and exploded and died on the spot.

Only more than 2,000 survived by chance.

But Lin Fan clearly felt that the realm of these surviving iron-eating ants had obviously improved a lot compared to before.

"The effect of the Soul-Feeding Immortal Pill is really good. But now, the number of Soul-Feeding Immortal Pills in my hand is limited. It is impossible to feed all of them to these iron-eating ants."

"Why not, I will continue to select some of these iron-eating ants to feed them."

Lin Fan thought for a while and patiently observed the iron-eating ant colony.

He selected 500 more ferocious iron-eating ants and fed them the Soul-Feeding Immortal Pill again.

This time, many iron-eating ants still exploded and died directly.

However, what surprised Lin Fan was that the 300 surviving iron-eating ants actually successfully advanced to the late stage of the Great Perfection of the Tribulation Crossing Realm. It seemed that it would not take long for them to advance to the realm of the True Immortal.

"My method was indeed correct. Although the efficacy of the Soul-Feeding Immortal Pill is good, the iron-eating ant colony is too large, and one Soul-Feeding Immortal Pill is not enough. Only precise feeding can do it."

After Lin Fan muttered to himself, he was about to continue to feed accurately when a powerful breath suddenly erupted from not far away from him.

I saw that the Iron-Eating Ant King, who had been in seclusion for more than half a year, had successfully broken through to the realm of the True Immortal.

The terrifying pressure emanating from it made Lin Fan's expression change slightly.

"Huh? In just half a year, you have advanced to the realm of the True Immortal? It seems that the Soul-Feeding Immortal Pill has a very good effect on you."

Lin Fan looked overjoyed.

Taking this opportunity, he made a master-servant agreement in the body of the Iron-Eating Ant King, and then tried to control the Iron-Eating Ant King.

Buzz!

The Iron-Eating Ant King flapped its wings and rushed forward like an arrow.

However, before the Iron-Eating Ant King rushed far, Lin Fan's expression immediately became extremely ugly.

"What's going on? My spiritual power is being consumed so quickly?"
