Mortal blood!

Buzz!

Lin Fan's mind moved, and the immortal medicine that Fairy Xueling gave him appeared in front of him.

His mind quickly swept over it, and Lin Fan picked up the necessary parts in an orderly manner.

The unnecessary parts were put away again.

"I have never refined an immortal pill until now. Next, I plan to refine a first-level tempering immortal pill." Lin Fan said secretly.

First-level tempering immortal pill!

This is the most common pill used for meditation and cultivation in the True Immortal Realm.

It can replenish the immortal power in the body of the True Immortal and improve the realm of cultivation.

It is precisely because of this that refining the first-level tempering immortal pill is much simpler than other immortal pills.

Even so, it is only relatively speaking.

Lin Fan dare not be careless at this moment.

Silently recalling the steps of refining the first-level tempering immortal pill, after arranging the required immortal medicines in order, he carefully checked the quality of the immortal medicine again.

After confirming that the quality of each immortal medicine was exactly the same as that of the first-turn Tempering Immortal Pill, Lin Fan activated the Black Flame Cauldron.

Whoosh!

As a stream of extremely pure spiritual power was injected into the Black Flame Cauldron.

A light golden flame instantly emerged from the bottom of the Black Flame Cauldron.

At the same time, the palm-sized Black Flame Cauldron, under Lin Fan's control, was suspended in the void and slowly rotated.

The jumping golden flame licked the surroundings of the Black Flame Cauldron, allowing the Black Flame Cauldron to be evenly heated.

At the same time, Lin Fan's divine thoughts also focused on the Black Flame Cauldron, carefully feeling the temperature changes in the Black Flame Cauldron.

Only when the temperature in the Black Flame Cauldron was almost exactly the same as the temperature for refining the first-turn Tempering Immortal Pill, Lin Fan quickly threw a silver thread grass into it.

Whoosh!

The temperature in the Black Flame Cauldron suddenly rose the moment the silver thread grass fell into it.

In an instant, the silver thread grass was burned black.

Soon, it turned into a pile of ashes.

Lin Fan, who was controlling the Black Flame Cauldron, frowned slightly.

"No, when I was controlling the Black Flame Cauldron just now, I clearly felt that the temperature in the Black Flame Cauldron should be fine. Why did the silver thread grass burn into ashes instantly after I threw it into it?"

Lin Fan thought carefully for a long time, analyzing his failure tirelessly like peeling silk from a cocoon.

Then after finding the corresponding solution, he heated the Black Flame Cauldron to the required temperature again, and then threw a silver thread grass into it.

Buzz!

This time, the Black Flame Cauldron shook slightly, and the silver thread grass inside was steadily suspended inside the Black Flame Cauldron.

Then, the temperature around it baked the silver thread grass dry and turned it into powder bit by bit.

"Almost done!"

Seeing this, Lin Fan was overjoyed.

With a thought, several control spells were cast in succession.

The Black Flame Cauldron, which was slowly floating in the void, instantly spun.

On it, the terrifying power of rules kept spreading.

The silver thread grass powder in the Black Flame God Cauldron was refined into a drop of emerald green liquid by the high temperature, which kept rotating at the bottom of the Black Flame God Cauldron and making a hissing sound.

Seeing this, Lin Fan was inexplicably happy.

He released his divine thoughts and carefully checked the situation in the droplet.

He found that the power of rules in this drop of silver thread grass had been completely dispersed by the power of rules in the Black Flame Cauldron.

The scattered power of rules of the five elements filled the Black Flame God Cauldron.

It was completed in a messy state.

Seeing this, Lin Fan frowned.

"The so-called purification is to remove the unnecessary power of rules in the spirit liquid. This process is quite complicated and requires great patience."

"This is also my first attempt to remove the unnecessary power of rules. I just don't know if it will succeed this time."

Lin Fan muttered secretly.

At this moment, he didn't dare to be careless at all.

With a thought, the power of the five elements rules was fully activated and slowly fell into the Black Flame Cauldron.

Then, the pure wood attribute rule power was completely left.

The gold attribute, fire attribute, earth attribute, and water attribute rule power mixed in it were extracted little by little.

This process seems simple, but it tests the patience of the alchemist.

Many alchemists who tried to make pills for the first time were defeated by the purification step.

Although Lin Fan had made a lot of pills when he was in the lower plane.

But this was the first time he did this.

Fortunately, the power of the five elements rules he cultivated had reached a great success.

Although the control of the five elements rule power could not be said to be arbitrary, it could be controlled skillfully.

As time passed, the wood attribute rule power in the Black Flame Cauldron became more and more concentrated.

The rule power of other attributes became thinner and thinner.

After only half an hour, the purification of the silver thread grass was completely completed by Lin Fan.

At this moment!

The silver thread grass spirit liquid that fell on the bottom of the Black Flame Divine Cauldron was gorgeous and extremely green.

It was like a small emerald, touching.

"It's done!"

Seeing this, Lin Fan was overjoyed.

Carefully controlling the Black Flame Divine Cauldron, he put the purified silver thread grass spirit liquid into a small white jade bottle.

Next, Lin Fan used this method to purify dozens of spiritual medicines such as Fire Nether Flower, Sunflower Water Linglong Grass, Black Snow Magnolia Flower, etc., which was considered to have completed the first step of purification in refining the first-level Quenching Immortal Pill.

Even so, Lin Fan was very excited.

"Purification is the most critical step in refining the first-level Quenching Immortal Pill. Purification is to gather all the required rule forces together. The next step of refining the pill is to reasonably integrate these purified rule forces together."

"And it is necessary to ensure that these rule forces are perfectly matched with each other. Otherwise, if a certain rule force is too strong, the cultivator will be backfired by the medicine when refining the pill."

"This is also the reason why many alchemists need a large number of medicine slaves to test the medicine."

When Lin Fan thought of this, his mind suddenly became clear.

But at this moment, he did not get carried away because he purified all the immortal medicines.

Calming down and concentrating his mind, Lin Fan started to refine the first-level Quenching Immortal Pill again after his mind was completely restored.

Huh!

Under the Black Flame Divine Cauldron, the light golden flame continued to emit heat.

In the Black Flame Divine Cauldron, all the purified immortal medicines poured by Lin Fan slowly merged under the action of high temperature.

At this time, Lin Fan was concentrating on urging his mental power and feeling the changes in the Black Flame Cauldron.

He found that the process of various rule forces fusing with each other in the Black Flame Cauldron was very difficult.

The collision of the rule forces in the purified immortal medicine and the rule forces of the Black Flame Cauldron, the collision of the rule forces of the immortal medicine and the rule forces of the immortal medicine...

For a while, the entire Black Flame Cauldron was constantly making crackling noises.

If it weren't for Lin Fan, who had read all the alchemy books that Xue Ling gave him.

He knew that this phenomenon was just a normal phenomenon in refining immortal pills, otherwise he would have doubted whether he had failed at this moment.

There was no words for a while, just waiting for Lin Fan to patiently control the temperature of the flame, just waiting for these rule forces to merge with each other.

The terrifying explosion in the Black Flame Cauldron gradually calmed down, and Lin Fan was completely relieved.

At this moment, a strange fragrance quickly emanated from the Black Flame Cauldron.

The rich aroma of medicine also came with it.

Seeing this, Lin Fan was immediately overjoyed.

With a flick of his finger, the lid of the Black Flame Cauldron opened instantly.

It was the size of ten thumbs, with a thin line like white jade running through the entire elixir.

It was exactly the first-level quenching elixir that Lin Fan wanted to refine!

Seeing that a whole furnace of elixir was successfully refined by himself so easily, Lin Fan was inexplicably surprised.

"It's done? It seems that refining elixir is not as difficult as imagined!"
