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

Li Lan didn't dare to be distracted in the slightest, fully absorbing and converting the spiritual energy of heaven and earth.

The nascent form of the new magic power vortex was initially very unstable, appearing and disappearing intermittently.

However, with the continuous gathering of magic power, this magic power vortex was gradually growing at a speed visible to the naked eye.

It seemed that in no more than two hours, it would be completely formed, becoming the same size as the previous four magic power vortexes.

However, at this moment, Li Lan discovered that the rotation speed of the four magic power vortexes gradually increased a lot.

Obviously, the medicinal effects of the breakthrough pill had begun to dissipate.

Seeing this, Li Lan hurriedly swallowed another one.

A similar warm current converged towards the dantian.

The medicinal power flowed into the four magic power vortexes respectively.

But this time, the four magic power vortexes no longer cooperated.

They were not appeased, and their rotation speed gradually increased, as if they were wild horses that had broken free from their reins, struggling to escape control.

Li Lan had to concentrate his divine sense, stabilizing the nascent form of the new magic power vortex while also taking care of the stability of the four formed vortexes.

Dividing his mind into five uses immediately made him feel immense pressure.

Before long, Li Lan felt a deep sense of fatigue袭来.

At the same time, it was as if countless fine needles were piercing through his skull.

Every time he concentrated his mind, it was like cutting flesh with a dull knife, causing unbearable pain.

Li Lan was very clear that this was a sign that his divine sense was about to be overdrawn.

Dividing his mind into five thoughts, each precisely controlled, was still too difficult for him at this moment.

Headaches came in waves like a tide, and Li Lan's body began to tremble slightly.

His hands unconsciously clenched into fists, and his knuckles turned pale due to excessive force.

Li Lan realized that his divine sense consumption was about to reach its limit.

And that magic power vortex that had just been born and had not yet fully condensed would need at least another hour to be completely stabilized and formed.

It was too late.

He decisively made a decision, directly dispersing the fifth magic power vortex.

The surging and rampant magic power scattered like birds and beasts, impacting every corner of the dantian.

Fortunately, there was a liquid film formed by the medicinal power of the breakthrough pill, repeatedly resisting the impact of these chaotic magic powers, protecting the foundation of the dantian from damage.

After a long time, the magic power condensed by the fifth vortex had been completely dissipated.

Without this uninvited guest, the remaining four magic power vortexes were like wild horses with reins on them, gradually returning to calm.

The first attempt to break through to the fifth level of Qi Refining ended in failure.

Li Lan also lost two breakthrough pills for this.

However, he didn't feel too frustrated at this time.

Since embarking on the path of seeking the Dao, Li Lan's cultivation has never been smooth sailing.

He had to fail many times before breaking through each realm.

He had long been accustomed to this.

Li Lan didn't waste time on disappointment or frustration, but immediately entered a state of deep meditation and reflection, summarizing the reasons for the failure while the iron was hot.

He carefully recalled the entire process in his mind, not letting go of any details.

There was nothing wrong with the breakthrough pill, and it was precisely because of its existence at the beginning that Li Lan was able to be so smooth.

It was not until the medicinal effect of the first breakthrough pill gradually dissipated that the initial signs appeared when he took the second pill.

The problem arose here.

This second pill had almost no effect.

After that, he seemed to have lost all assistance, completely relying on the strength of his own divine sense to stabilize the four magic power vortexes.

If it was only for a short while, it would be fine, but dividing his mind into five thoughts while also persisting for at least an hour to allow the fifth magic power vortex to stabilize and form was completely beyond Li Lan's ability.

Li Lan quickly summarized the lessons of failure: his speed of condensing magic power vortexes was a bit too slow.

It was precisely because of the speed that the series of events that followed occurred.

If his speed was fast enough, he could have completely formed the fifth magic power vortex before his divine sense was completely overdrawn.

After finding the answer, Li Lan couldn't help but frown.

There are many factors that affect the speed of condensing magic power vortexes, the most critical of which is spiritual root aptitude.

With excellent spiritual root aptitude, the speed of circulating the heavens and refining the spiritual energy of heaven and earth will be faster, and the magic power vortex will condense faster, and vice versa.

Li Lan has pseudo-spiritual root aptitude, and his cultivation speed is inherently slow.

The reason why he was able to break through to the fourth level of Qi Refining in just a few years, in addition to his own doubled efforts, was also due to the cultivation technique and the spiritual vein of this Immortal Trace Valley.

The location where he is now has a richness of heaven and earth spiritual energy that is not weaker than the Ding-grade cultivation cave dwelling of a normal spiritual vein.

Since moving to this Immortal Trace Valley, Li Lan has always felt that his speed of absorbing heaven and earth spiritual energy was already fast enough, but now it seems that his speed of refining magic power still needs to be improved.

Spiritual root aptitude is innate, and this point cannot be changed. Then, if you want to change the speed of refining magic power, you can only rely on external force.

In the world of cultivation, there are many things that can change a cultivator's acquired cultivation speed, such as elixirs, magical instruments, cultivation techniques, and spells.

Among them, the most widely used is the spiritual vein cultivation cave dwelling.

Normal spiritual veins are usually divided into four grades according to the richness of spiritual energy: A, B, C, and D. The A area in the center has the richest heaven and earth spiritual energy, while the D area is the worst.

The richness of spiritual energy in the location where Li Lan is now is equivalent to the D area.

Since the heaven and earth spiritual energy contained in the D area is not enough for him to break through to the middle stage of Qi Refining, Li Lan thought of going to the more spiritual-energy-rich C area to try.

Of course, he is not going to buy a spiritual vein cultivation cave dwelling quota to cultivate in the normal spiritual veins controlled by those sects.

One reason is that these high-level cultivation resources are rarely sold to low-level cultivators, and the second reason is the price.

With Li Lan's current wealth, buying some Ding-grade cultivation cave dwellings can barely be afforded, but the cultivation cave dwellings above C-grade are not something he can afford now.

However, there are always more solutions than difficulties.

Although Li Lan cannot afford the cultivation qualification of a C-grade cave dwelling for the time being, he has a ready-made spiritual vein in front of him.

Although the spiritual vein in this Immortal Trace Valley has been abandoned on the surface, Li Lan accidentally discovered that the richness of the spiritual energy here is not inferior to that of a normal spiritual vein.

Since the outer area is like this, then the central area inside should also be the same.

Over the years, Li Lan has always wanted to verify whether the depths of Immortal Trace Valley are indeed as he guessed.

However, due to the experience he encountered in this valley for the first time, he forcibly suppressed this idea, putting all his mind on self-preservation and cultivation, and not provoking unnecessary trouble.

Until today, when he encountered a bottleneck in cultivation that he couldn't get around, Li Lan once again had the thought of entering it and exploring it.

He doesn't know whether the Foundation Establishment Stage expert he sensed back then is still in the valley.

So many years have passed, presumably they should have left long ago, right?

But regardless of whether the other party is still there or not, for his own future and in order not to affect future cultivation, Li Lan has made up his mind to take a risk.
