The process of refining the Earth Spirit Pill and Wind Spirit Pill was not too difficult for Lu Yuan.

The difficulty in refining these two elixirs lies not in the techniques, but in the collection of raw materials.

Taking the Wind Spirit Pill as an example, Lu Yuan wanted to refine a Wind Spirit Pill that could assist in the cultivation of the special magical power, Wuxiang Gangfeng.

It is necessary to use the essence and blood of the wind type bird demon king as the medicine.

It goes without saying how difficult the Demon King is to kill.

After all, it was comparable to the existence of the Dan Formation Stage.

The last drop of the wind demon king's essence and blood in Lu Yuan's hand.

It was dug out from between his teeth.

When Feng Linggen was building the Heavenly Dao foundation, Lu Yuan discovered that he could increase the success rate of his Heavenly Dao foundation building to 98% by using only two-thirds of the wind demon king's essence blood.

He kept the remaining one-third of the wind demon king's blood essence.

It is precisely because of this "frugal and frugal" style.

This gave Lu Yuan the capital to refine the Wind Spirit Pill and practice the 'Wuxiangangfeng'.

As for the Earth Spirit Pill, the material used by Lu Yuan as a medicine guide was the remaining black tortoise shell.

Although that piece of black tortoise shell was used a lot during Lu Yuan's foundation building process.

But a black tortoise shell that is five thousand years old is almost equivalent to a monk at the fifth level of the elixir formation stage.

Although the black tortoise shell obtained by Lu Yuan was only a small part of it.

But Lu Yuan broke through the foundation building period, and still couldn't use it up.

And it is precisely because of these two treasures.

That's why Lu Yuan coveted the herbs in this medicine garden so much.

Now with the departure of Master, he will also go down the mountain soon.

The time is right, the place is right, and everyone is in place. It's time to backstab... No, it's time to ask Master in advance for some cultivation resources!

As a decisive person, Lu Yuan quickly removed all the herbs he needed from the medicine garden.

Then he quietly returned to his empty cave under the cover of night.

The entire process was performed professionally and the escape route was reasonable.

At first glance, it seemed that it had been planned long ago.

After returning to his cave, Lu Yuan felt relieved.

In fact, he had planned what happened today for a long time.

Seeing that the time was right, I took action decisively!

His master, Han Yuanshan, has now gone to attend the wedding banquet of a Taoist friend.

The monk's wedding banquet was unusual, not to mention that the monk who could be regarded as a friend by Han Yuanshan must also be in the alchemy stage.

When such a monk holds a wedding banquet, he will most likely discuss Taoism with other people.

Therefore, it will take almost a year for Han Yuanshan to come back after leaving home this time.

And as long as he goes down the mountain before the master comes back, he can avoid it perfectly.

If you don’t take action now, when will you take action!

Knowing that he only has one year to 'eliminate the stolen goods'.

Lu Yuan decisively started refining the Wind Spirit Pill and the Earth Spirit Pill.

Because he still has a lot of luck left.

So the process of refining the Earth Spirit Pill and Wind Spirit Pill this time was very smooth, but it took a little longer.

It took Lu Yuan a month to refine the two elixirs together.

Although it took a long time, Lu Yuan couldn't help but look happy when he saw his harvest.

[Wind Spirit Pill (Perfect)]

[Level: Foundation Building Period]

[Effect: After taking it, the wind spiritual affinity in the body can be increased in a short period of time, and the wind spiritual root qualification can be permanently increased by 50 points]

...

【Tulingdan(Perfect)】

[Level: Foundation Building Period]

[Effect: After taking it, the affinity of earth spiritual power in the body can be increased in a short period of time, and the earth spiritual root qualification can be permanently increased by 50 points]

...

Looking at the two elixirs in his hand, Lu Yuan temporarily put them away after admiring them for a moment.

Because before taking two pills and practicing special magical powers.

Lu Yuan has another more important matter.

I saw that in the course of this month, Lu Yuan's system panel had been refreshed many times.

[lv10. Metaphysical alchemy: 10000/10000]

[To meet the requirements for skill advancement, do you want to advance?]

[Current advanced success rate: 63%]

Not surprisingly, Lu Yuan saw that his metaphysics and alchemy skills had finally reached the full level.

Although the success rate of skill advancement is not high at the moment, it doesn't matter... I have a way!

[Ding! The special effect is activated at the time of selection, and the luck value is temporarily doubled...]

At the same time that Lu Yuan opened the Time of Chosen.

The success rate of advanced metaphysical alchemy has also changed accordingly.

[Current advanced success rate: 98%]

The auspicious time has arrived, go ahead!

[Ding! Metaphysics and alchemy are being advanced...]

[The metaphysical alchemy has been advanced successfully, please choose the direction of advancement...]

[1. Improve the basic success rate of alchemy]

[2. Increase the upper limit of luck when refining alchemy]

【3. Make alchemy available for other purposes】

Lu Yuan looked at these three advanced directions and made a choice after thinking for a moment.

[Ding! Metaphysics alchemy has been advanced successfully, and new skills have been obtained: Divine Soul Alchemy]

[Soul Alchemy Technique: The Way of Technique, which can be used to communicate with the gods!]

[lv1. Divine Soul Alchemy: 0/10000]

[Effect: A special alchemy technique fused with the soul, which can be used to make alchemy, fight against enemies, and even practice]

Although there are not many descriptions of the alchemy of the soul.

But its effect is absolutely overwhelming.

After Lu Yuan closed his eyes and absorbed all the essentials of the soul alchemy technique, he slowly opened his eyes.

The joy in his eyes couldn't be hidden.

This advanced skill... is even more exaggerated than he thought!

Lu Yuan stretched out his palm, and a ball of blue flame instantly appeared in his palm.

Not long after, this green flame began to condense.

In the end, it turned from a ball of magical flames into a round and smooth blue pill.

[Qing Yan Dan (Soul)]

[Level: Third level of foundation building]

[Effect: After detonating, it can explode into a blue flame attack comparable to the third level of the foundation building stage]

[Shelf life: three days]

In terms of effect, there is actually not much difference between Qingyan Pill (Soul) and ordinary Qingyan Pill.

But considering that this Qingyan Pill (soul) was made by Lu Yuan without relying on any external objects, and only relying on his own spiritual power and some Qingyan power, this is undoubtedly very amazing.

Because this method is not much different from creating things out of thin air.

Even the use of divine soul power and spiritual power to refine special elixirs is not the most dominant aspect of divine soul alchemy.

The most overbearing part of the soul alchemy technique is soul refining!

In other words, Lu Yuan can use his soul as an elixir to temper it!

Just listening to it might temper your soul.

But after the soul is tempered to a certain extent, what replaces it... is Nascent Soul!

Generally speaking, only monks in the elixir-forming stage have the means and ability to cultivate the soul.

But Lu Yuan relied on the soul alchemy technique to do this during the foundation building stage.

Although he cannot refine the Nascent Soul like the monks at the Dan-formation stage.

But he can still do it to greatly increase the strength of his soul.

If his soul can be strong enough.

Then wait until it is time to form the elixir.

He can rely on his powerful soul to force all spiritual roots to fuse.

In this way, it is equivalent to greatly improving the success rate of Lu Yuan's pill formation.

It is no exaggeration to say that this advanced skill has transformed Lu Yuan!

After a period of excitement, Lu Yuan quickly regained his composure and calmed down.

Now that the metaphysical alchemy has been advanced successfully.
Chapter completed!
