At the beginning, I cleaned the Sutra Library and completed the incomplete skills.

According to the locations marked on the sand table, Li Lan easily found several medicine gardens.

When Guangji Temple moved away from this place, they only took away most of the mature spiritual herbs and plants.

Some seedlings that were inconvenient to transplant were forced to stay behind.

Now, these spiritual plants have benefited Li Lan instead.

After so many years, these seedlings have long since matured.

With the help of the sand table, Li Lan's efficiency in directing the spirit bean soldiers to pick herbs was significantly improved.

In addition to this sand table, there was another place in the Guangji Temple ruins that was quite interesting.

A spirit bean soldier pushed open a stone door in the corner and stepped inside.

Instantly, a scorching hot aura rushed towards them.

There was nothing to provide light in the cave, but it was as bright as day.

All the walls here were made of translucent spirit rocks.

The faintly flickering orange-red flames within illuminated the entire cave in a fiery red hue.

The air in the cave was scalding and dry, and every breath felt like swallowing flames.

The deeper they went, the stronger this feeling became.

Layers of heat seemed to distort even the air itself.

The scorching temperature seemed as if it would ignite the spirit bean soldier completely in the next second.

Through the senses of the bean soldier, Li Lan clearly saw that these spirit rocks around them seemed to be baked, constantly emitting heat.

Walking to the end, independent stone chambers were carved out on both sides of the wall.

Each stone chamber was very simple.

Only a futon and a furnace made of spirit rock were placed inside.

According to the information revealed on the sand table, this place was specifically used for refining elixirs and magical artifacts.

As long as mana was injected into it, even if the cultivator did not practice fire-attribute techniques, they could use these special spirit rocks to generate suitable flames.

Li Lan had previously heard Miao Chenfeng say that the elixirs and magical artifacts refined using this kind of spirit fire had different degrees of improvement in success rate and the effect of the finished product.

As for how much it would improve, it depended on the cultivator's control over the spirit fire and the grade of the spirit rock.

Li Lan had not yet come into contact with the art of refining magical artifacts.

However, he had dabbled in refining elixirs.

Now that he had accidentally found such a treasure land, he naturally felt a little itchy and wanted to try out this so-called spirit fire to see how useful it was.

Although Li Lan himself could not come here in person, he still had spirit bean soldiers in his hand.

After seeing that the spirit bean soldiers with more than twenty years of cultivation possessed mana and could breathe in spiritual energy, Li Lan had been thinking.

Since they could cultivate like cultivators, then refining elixirs and magical artifacts should not be a problem, right?

For the next seven days, Li Lan successfully refined a spirit bean soldier with more than twenty years of cultivation using walnut-sized purple sandalwood spirit beans.

Anyway, there was only one Spirit Dividing Pickaxe, and the remaining bean soldiers were idle anyway.

He simply issued an order, letting this spirit bean soldier plunge into the spirit rock cave and begin to try refining elixirs.

Since the bean soldier was only at the first level of Qi Refining, it could not refine elixirs of too high a grade.

Li Lan simply had it start refining from the most basic Foundation Establishment Pill.

The materials for this type of elixir were not expensive, so he would not feel bad even if the furnace exploded every time.

After trying it out, Li Lan discovered that spirit bean soldiers with twenty years of cultivation could not do this kind of fine operation.

They had great difficulty controlling the heat.

However, if Li Lan's divine sense was completely focused on the bean soldier, he could successfully refine a few furnaces of elixirs.

This was enough to show that the current spirit bean soldiers could not refine elixirs independently, but that did not mean they could not do it in the future.

Perhaps the purple sandalwood spirit beans with seventy or eighty years of cultivation could easily do it.

This was undoubtedly a good sign.

If the bean soldiers could refine elixirs autonomously, Li Lan could also save a lot of time and energy to do other things.

In the next three months, Li Lan cultivated to the bottleneck of the fourth level of Qi Refining.

The mana in his dantian had already reached the maximum that it could accommodate.

Unable to continue absorbing the spiritual energy of heaven and earth, he had no choice but to temporarily devote his energy to other aspects.

During this period, in addition to controlling the spirit bean soldier at the first level of Qi Refining to mine at full strength, Li Lan successfully refined three Breakthrough Pills.

Three months later, he finally gathered enough spirit stones to cover the entire cave dwelling.

Following the appearance of the spirit rock cave, Li Lan inlaid spirit stones one by one in his temporary cave dwelling.

Although this simple cave dwelling was not large, only enough for one person to live in, it still consumed more than ninety spirit stones.

After the decoration was completed, the cave dwelling instantly became different.

The faint blue light intertwined, like a flowing wave of water rippling in the cave dwelling.

The flickering light illuminated the entire cave dwelling like a dream.

So many spirit stones piled together emitted a very considerable amount of heaven and earth spiritual energy.

The spiritual energy in the cave dwelling was so concentrated that it was almost tangible, like a layer of soft blue gauze slowly flowing in the air.

Li Lan's cave dwelling was located on the periphery of Immortal Trace Valley.

The concentration of spiritual energy here was equivalent to the D-grade area of a normal spiritual vein, which was already quite good.

But now, compared with this cave dwelling covered with spirit stones, it was a small matter compared to a great one.

If the heaven and earth spiritual energy on the periphery of Immortal Trace Valley was compared to a trickle, then the spiritual energy in this spirit stone cave dwelling could be regarded as the surging Yangtze River.

Being in this place, he did not even need to guide it deliberately.

Just simple breathing, those heaven and earth spiritual energy seemed to be summoned, spontaneously and actively approaching him.

Seeing this situation, Li Lan did not hesitate and quickly sat down cross-legged.

After adjusting his state to the best, he took out a Breakthrough Pill and swallowed it.

Feeling the medicinal power dissolving in his body and merging into his dantian, Li Lan mustered all his spirits and focused his attention on launching an attack on the fifth level of Qi Refining again.

With the help of these spirit stones covering the cave dwelling, Li Lan's speed in gathering the fifth mana vortex this time was particularly amazing.

He hardly felt any resistance and had already compressed the mana vortex to a preliminary scale.

It was not until the new mana vortex condensed for the most part that the other four formed vortices barely reacted.

They began to restless and ramble around.

But at this time, how could it be too late?

After the medicinal power of the Breakthrough Pill completely disappeared, Li Lan took another one, while using his mind for five purposes.

While using his divine sense to take into account the stability of the four formed vortices, he accelerated the refining of the heaven and earth spiritual energy, compressing and condensing the fifth vortex.

Time passed by every minute and every second.

In the end, Li Lan successfully condensed the fifth mana vortex completely before his divine sense was exhausted.

The rest was much simpler.

According to the cultivation experience left by those predecessors he had watched in the past, he gradually stabilized the balance between the five mana vortices.

When they all slowly rotated in his dantian in a harmonious pattern, Li Lan also successfully crossed the first watershed of the Qi Refining stage.

Formally stepping into the middle stage of Qi Refining.
