The woman surnamed Mu had always treated Han Li with an indifferent attitude, which actually made him more satisfied.
The best outcome would be for her to completely forget about this place and not come to disturb his cultivation—that would make him even happier.
After another month passed, Han Li finally managed to comprehend the Spirit Restraining Formation to about seventy or eighty percent.
Once he had achieved this level of comprehension, Han Li didn't hesitate at all and immediately set up the Spirit Restraining Formation outside his cave dwelling based on what he had learned.
As a result, the faint spiritual energy fluctuations from the formations disappeared completely.
Looking at the small stone mountain from the outside, not a single trace of abnormality could be detected.
Han Li was very satisfied with this.
Over the next two or three months, the refinement of the Soul Resonance Pearl and the removal of the Wind Spirit Force were both successfully completed, one after another.
What surprised Han Li was that after the Soul Resonance Pearl had been refined to the point where it resonated with his spiritual sense, he didn't experience any headaches or discomfort whatsoever.
It seemed that the Crying Soul Beast's unexpected evolution had also caused unforeseen changes in the Soul Resonance Pearl that was linked to its life.
Han Li was overjoyed.
As for the Wind Spirit Force's evil energy, although it had been extremely difficult to force out of his body in the beginning—each time he tried to drive it out, he would become completely exhausted.
Once most of it had been expelled, handling the remainder became much easier.
Not only did the pain from the evil energy's flare-ups decrease significantly, but the time needed to force it out was also greatly shortened.
During the last few attempts, Han Li easily and effortlessly cleared away all the remaining evil energy.
After carefully checking himself several times and confirming that there were no more abnormalities in his body, he finally felt at ease.
With the most pressing matters handled, Han Li turned his attention to cultivation and the refining of the Nine Curve Spirit Ginseng medicinal pills.
As for cultivation, after thinking about it for several days, he decided to simultaneously cultivate the fourth layer of the Grand Development Technique and the Green Yuan Sword Art.
Because based on his previous Core Formation experience, it seemed that having a powerful spiritual sense was greatly beneficial for breaking through bottlenecks.
Even though the fourth layer of the Grand Development Technique was extremely difficult to cultivate, Han Li still planned to attempt it.
After all, even if an exceptionally powerful spiritual sense didn't really help much with condensing a Nascent Soul, it still offered numerous advantages in combat and in outmaneuvering one's enemies.
Even if it delayed his entry into the False Nascent Soul stage somewhat, he didn't consider it a wrong choice.
This amount of time, he could still afford to spend.
As for the matter of refining the Nine Curve Spirit Ginseng medicinal pills, Han Li naturally wouldn't be careless about it.
Other ingredients were one thing, but the Nine Curve Spirit Ginseng, the eighth-grade Demon Companion Grass, and the Agate Horn—these three materials were simply impossible to find anywhere in Tian Nan, and even spirit stones couldn't buy them.
If the pill refinement failed, Han Li would have absolutely nothing he could do except stare blankly.
Therefore, while cultivating, he also began studying the Nine Curve Spirit Ginseng medicinal formula, and he frequently refined other medicinal pills whose processes and techniques were similar to those in the formula, using this to improve his own pill-refining skills.
Just like that, amid constant cultivation and pill-refining, time trickled by bit by bit.
During this period, Han Li also learned the demon race's written language, planning to figure out exactly what was recorded on the copper pieces and beast-skin book in his possession.
With Han Li's photographic memory, he naturally mastered the ancient demon script without difficulty, and he first translated the contents of the beast-skin book.
The beast-skin book contained a demon race cultivation technique called "Gale Nine Transformations." After reading it for a while, Han Li discovered that this technique seemed to be specifically designed for avian demon beasts. It included a set of incantations, a movement technique, and two secret arts.
The incantations and movement technique were one thing—they were entirely meant for demon cultivators. Unless he had the powerful physique of the demon race, cultivating even to the halfway point would cause his body to explode and kill him.
As for the two secret arts, the Wind Concealment Technique was essentially the Nameless Breath Concealment Technique he had previously learned. It was just that the Nameless Breath Concealment Technique had been slightly modified to make it more suitable for human cultivation.
For Han Li, it only served as reference material and held no real value.
But the other secret art, the "Blood Shadow Escape," truly piqued Han Li's interest.
As the name suggested, this so-called "Blood Shadow Escape" was in essence an uncanny escape technique that harnessed the power of one's vital blood to instantly flee over a hundred li away.
Escape techniques like this, which borrowed the power of vital blood to instantaneously unleash formidable abilities, were actually possessed by many sects, particularly demonic path cultivators.
But this Blood Shadow Escape was somewhat different from the secret techniques of humans.
