After giving a series of instructions, you began your seclusion in the branch of the Immortal Arrival Sect.
In the days that followed, you spent half of your time each day improving your cultivation, and the other half fully devoted to practicing your Pill Refining Technique.
You could say that every day, apart from cultivating, you were refining pills, with no time for rest at all.
If this were your previous life, you would have died of exhaustion in less than three days.
In the second year, your cultivation showed a slight improvement, but it wasn't significant.
After all, your current cultivation level was already quite strong; for a normal Chosen at your stage, breaking through would take hundreds, thousands, or even tens of thousands of years.
So this was a normal phenomenon!
During this period, your cultivation didn't improve much, but your Pill Refining Technique advanced by leaps and bounds.
At this point, you had already become a seventh-grade alchemist!
In fact, the rapid improvement in your Pill Refining Technique was due to several reasons.
First, you had previously engaged in deep simulation and seen a lot of pill refining experiences, which helped you avoid many detours.
Second, you had the buff of the Orange Talent, Pill Dao Saint Hand.
Third, your current strength was very strong, and it's well known that the stronger you are, the better your comprehension.
This is what is meant by "master one and master all."
With your current strength, learning Pill Refining Technique was undoubtedly much faster than when you were at a lower level.
Calculating the time, you realized Bai Ruoxue should be appearing again.
If you wanted to obtain the Heavenly Profound Sword, it was about time to set off.
After pondering for a moment, you shook your head.
Forget it.
The Heavenly Profound Sword would be helpful, but not as much as you imagined.
Moreover, you had other plans this time, and it wasn't wise to offend Bai Ruoxue.
As for using the Meek Person talent to deceive Bai Ruoxue?
Not reliable!
After all, if she returned to the Eastern Regions and went inside that Bronze Gate once, recovering her full strength, it might expose you.
Having thought it through, you continued to focus on your secluded cultivation and improving your Pill Refining Technique.
In the blink of an eye, several years passed.
In the tenth year, your Pill Refining Technique advanced to the immortal-grade.
After that, it became much harder to improve your Pill Refining Technique.
Lu Wuya and Mo Jingtian were not just at the immortal realm.
Otherwise, it would have been unlikely for Lu Wuya to set up a formation beyond the immortal-grade.
Your Formation Dao had broken through to the immortal-grade, but unlike Pill Refining Technique, formations could be comprehended and didn't require as many resources.
So, you didn't leave Spine Mountain.
Instead, you continued to cultivate the Formation Dao.
In the blink of an eye, decades passed!
In the fortieth year, you successfully broke through to become a third-grade Immortal Formation Master.
By this time, the formation left by Lu Wuya held no more secrets for you.
You estimated that when Lu Wuya set up this formation, he was likely a third-grade or fourth-grade Immortal Formation Master!
As for why you say possibly a fourth-grade Immortal Formation Master?
Because you felt that as a third-grade Immortal Formation Master, setting up this formation would be quite strenuous.
This was a composite formation.
It used a large number of third-grade immortal-grade formations, intricately arranged.
If it were only a third-grade Immortal Formation Master, completing the setup might take hundreds of years.
You remembered that during the time of Lu Wuya and Mo Jingtian, there was also Heavenly Thunder.
This formation was likely set up in a short period.
Of course, it's also possible that the Heavenly Thunder in the Southern Regions was limited in power and couldn't harm very strong practitioners.
So, at that time, Lu Wuya might have set up the formation while withstanding the Heavenly Thunder.
This possibility is actually quite high.
After all, the information you previously obtained suggested that Mo Jingtian had withstood the Heavenly Thunder to break out of the Southern Regions.
Therefore, Lu Wuya, who was with Mo Jingtian, might also have been able to withstand the Heavenly Thunder.
After all, during your previous simulations, when you experienced the Heavenly Thunder, your strength was still too low.
You didn't have an accurate assessment of the actual power of the Heavenly Thunder.
But no matter what, Lu Wuya's formation skills were either at the third-grade or fourth-grade Immortal Formation Master level.
Personally, you leaned towards the fourth-grade.
After all, would a Chosen like Lu Wuya spend hundreds of years setting up a formation to help others avoid Heavenly Thunder?
You thought, if it were you, you definitely wouldn't!
With that time, it would be more worthwhile to improve your cultivation or enhance your Formation Dao.
