During that time, he only went out once, leaving Shuiyun Pavilion for a little over an hour before returning.

It turned out that he went to a large cultivator's shop in Tianhai Immortal City and sold off some of his useless miscellaneous cultivation manuals, low-grade magic weapons, and inferior mid-grade magic weapons.

I obtained more than two thousand spirit stones in total.

I also bought a few more detailed maps of the cultivation world in the Yunmeng Mountains.

And detailed information about the Righteous Alliance, the Heavenly Demon Sect, and the Ten Thousand Beasts Mountain.

Furthermore, he also used over ten thousand spirit stones to upgrade the cauldron in his dantian once again.

After the cauldron was upgraded, three more of the nine stars were lit up.

Lu Xuan can now use the treasure cauldron to accelerate the ripening of various pills below the mid-stage of Foundation Establishment.

Moreover, the timeframe has once again become about a month!

The quantity remains nine.

Lu Xuan guessed that the number of crops that could be accelerated by the treasure cauldron could not be increased any further!

In other words, it can accelerate the growth of nine spiritual herbs below the mid-Foundation Establishment stage in one month!

Nearly a hundred Foundation Establishment stage elixirs a year!

As for Qi Refining level spiritual herbs, for Lu Xuan, who is currently at the ninth level of Qi Refining, they are useless whether he sells them for spirit stones or uses them to refine pills.

From now on, we'll accelerate the maturation of Foundation Establishment stage spiritual herbs.

They sell for a high price.

In the future, if I want to refine some top-tier pills for the Qi Refining stage, I will only be able to use spiritual herbs from the early Foundation Establishment stage!

Because after Lu Xuan broke through to the ninth level of Qi Refining, he clearly sensed that his five spiritual roots had reached a major bottleneck!

Breaking through the tenth, eleventh, and twelfth levels of Qi Refining, each minor realm should present a major bottleneck for his aptitude.

Only by finding the legendary supreme elixir for the Qi Refining realm can he possibly cultivate to the Great Perfection of Qi Refining.

To refine these pills, one needs some spiritual herbs for those in the early stages of Foundation Establishment.

Therefore, Lu Xuan plans to only accelerate the ripening of spiritual herbs in the early stages of Foundation Establishment from now on.

As for the spiritual medicine that accelerates the maturation of the Foundation Establishment stage, it takes three months to mature.

As for late-stage Foundation Establishment elixirs, the spiritual power of the cauldron is currently insufficient, so it is estimated that it cannot accelerate their ripening!

This is a period of seclusion for spiritual cultivation.

It was a very rewarding experience!

Next, he needs to find a way to join the Tianhai Sect.

Besides that, he learned the art of alchemy.

Lu Xuan had inquired about such top-tier elixirs, and they were rarely found.

Only a tiny number might appear within those major sects and families; cultivators outside can forget about ever getting in touch with them.

Even if you join a sect, you won't have access to those kinds of pills unless you're a true core disciple.

If a cultivator has decent aptitude, they won't need those top-tier pills for the Qi Refining stage.

For a cultivator like Lu Xuan, who possesses the aptitude of five spiritual roots, the ninth level of Qi Refining is arguably the absolute limit.

Unless a major sect or family is willing to spend extremely precious Qi Refining Pills to cultivate a useless cultivator with five spiritual roots.

This situation has never occurred in the world of cultivation since ancient times.

Unless it's a direct relative of a Core Formation expert, perhaps it's possible!

After all, this kind of pill is too expensive on the market; one pill costs thousands of spirit stones!

Most importantly, it's available at a price but not in demand...

Therefore, Lu Xuan wanted to study the art of alchemy. In the future, he would accelerate the ripening of spiritual herbs and refine pills himself.

First, finding the formulas for those top-tier elixirs is also a difficult task.
