Everyone knows that Homeostasis Powder refers to a type of Yellow Level elixir that ranges from one to three stars. This basic elixir is most needed and useful for restoring spiritual energy and healing wounds; no other effects can match that, so it’s quite straightforward to describe it as Homeostasis Powder.

To more clearly distinguish between grades, elixirs are classified not only by the usual Heaven, Earth, Mysterious, and Yellow ranks (from one to nine stars) but also into upper, middle, and lower grades.

One to three stars are considered lower grade, four to six stars are middle grade, and seven to nine stars are upper grade. This classification isn’t unnecessary; it has real-world relevance.

Every time an elixir breaks through a star level, it represents an improvement in quality and efficacy, which is a quantitative change. But once it breaks through a grade, it signifies a deeper qualitative change.

Take Yellow Level elixirs as an example; they are not as simply classified as lower-grade ones. The types and effects of middle-grade Yellow Level elixirs start to become diverse, with more than ten common categories.

Not only do they contain more concentrated spiritual energy, but generally speaking, the healing effects of middle-grade Yellow Level elixirs are better, also being more refined and targeted.

For example, the Healing Pill, which has similar effects to Homeostasis Powder, can not only better treat wounds and restore spiritual energy but also has a significant pain relief effect.

Or consider the Spirit Nurturing Pill, used during cultivation, which provides a large amount of spiritual energy while helping Spirit Masters enter a better cultivation state.

Additionally, there’s the Nurturing Origin Pill, used for children approaching the “Spirit Awakening” phase. It enhances their abilities while maximizing the softening of the spiritual energy input pathway, allowing even children with weak meridians, who haven’t yet become Spirit Masters, to use it, and so on.

The difference between three stars and four stars may seem small, but the gap between grades is substantial.

The Homeostasis Powder that surprised him was not a common four-star Healing Pill; it was because the raw materials were undeniable.

This relatively simple Yellow Level elixir, with a straightforward formula and production process, also has a looser finished structure. A knowledgeable person wouldn’t need the help of an alchemist to easily analyze the authenticity, grade, and even the raw materials and proportions of the elixir.

Yin Jiuxiao happened to possess that ability.

It was obvious that this Homeostasis Powder used a very common formula, consisting of only two ingredients—low-grade medicinal base and Round Wheat.

Even the top alchemists in the Spirit World could not break through the limitations of raw materials to produce a four-star Homeostasis Powder with such a rich concentration of spiritual energy that defied logic.

The examination results were undeniable. Yin Jiuxiao examined it three times to ensure he hadn’t made a mistake.

His probing spiritual energy clearly reflected back that this was indeed a Homeostasis Powder whose spiritual energy concentration and elixir efficacy had reached four-star levels, with twenty pills in that bottle, all without exception.

Yin Jiuxiao’s expression gradually grew serious.

He realized that while the change in such basic elixirs seemed small, if it could be produced on a large scale, it would be significant for pharmacies that needed to ship out large quantities.

Not to mention, the price of raw materials for a four-star Healing Pill was different. No matter how cheap the formula, the cost would still be over a thousand. The vast difference in cost and the huge market for basic healing elixirs…

This one bottle of Homeostasis Powder could serve as a small stone cast into the waters of the elixir market.

How did that chattering little crow manage to get this?

Moreover, this thing hadn’t appeared in his memory of the Spirit World.

Since his rebirth, this was the first thing he encountered that was somewhat different from his previous life.

How interesting.

Indeed, this was already the second life that Yin Jiuxiao was living.

Generally speaking, it seemed that only those with unresolved grievances or regrets would have the obsession with rebirth, but honestly, Yin Jiuxiao had no such grievances in his first life.

He had avenged all he needed to avenge, and had become the most powerful and respected person in the Spirit World, standing at the pinnacle of society.

Though the process had its twists and turns.

When Yin Jiuxiao was born, the Yin family was already a top family in the Spirit World. His grandfather was the first Sword Master in the Spirit World at that time, and the family was filled with talented uncles and cousins. The Yin family had the renowned “Nine Heavens Exquisite Cloud Sword” as part of their legacy, and no one dared challenge them on the continent.

His father also inherited the family’s unique skills and was extraordinarily talented, surpassing even his grandfather. He gained fame in the Spirit World at a young age, and among his peers, he was the one who no one dared to challenge for first place.

At that time, the Yin family was in its prime, a firmly established top force on the continent.

As the sole heir, Yin Jiuxiao attracted attention when he tested his spiritual potential at the age of three, and he did not disappoint the expectations of the Yin family.

A ten-layer talent was merely the foundation for him. More importantly, during the testing, when the Spirit Testing Stone projected his spiritual marrow, instead of projecting on the ground like normal, the shadow of a sword appeared directly on him. Under that light, he and the Nine Heavens Exquisite Cloud Sword seemed to merge into one.

This was the Spirit World’s first instance of a naturally-born sword bone, unprecedented and unmatched. The then Family Head, Yin Jiuxiao’s grandfather, was overjoyed and specially invited the family’s ancestral hall to officially name his extraordinary grandson, directly using the words “Jiuxiao” from the family’s spiritual marrow, and he was immediately recognized as the young master of the Yin family, which showed how highly he was valued.

At first, Yin Jiuxiao lived up to the expectations of his elders. After “Spirit Awakening,” he became a Yellow Level Three Star, hailed as the continent’s number one genius, cultivating at a nearly monstrous speed, and by the age of seven, he had already broken through the ranks, becoming the youngest Earth-Level One Star Spirit Master in the Spirit World.

But it was during that year, when he was seven, that the Yin family encountered a calamity.

After his father vanished, leaving behind a letter when Yin Jiuxiao was three, stating he had secured an heir for the family, there was no news for four years.

That year, when he turned seven, the soul lamp left in the ancestral hall by his father extinguished.

When the lamp extinguished, it signaled death. His grandfather had yet to mourn when another calamity struck—the Yin family’s territory suddenly faced an unprecedented disaster.

A massive rift of demonic qi opened up, and the invasion of demonic energy swept through, leaving destruction in its wake.

This demonic energy was vicious and sudden, and the rift appeared in the main city in an extremely rare manner, spreading at an unprecedented rate and scope.

In just a few days, most of the northern state of the Spirit World where the Yin family was located fell.

To prevent the spread from worsening and engulfing the entire continent, Yin Jiuxiao’s grandfather, along with dozens of powerful elders from the family, sacrificed themselves in an explosion of spiritual marrow to counter the demonic energy and seal the rift, finally bringing an end to the catastrophe.

However, that incident decimated all the Yin family’s top forces. None of those who went to seal it returned, and the two uncles left behind to guard the family barely clung to life, choosing to retreat into seclusion to recover, not knowing how long it would take for them to emerge.

With half of the backbone of the Yin family dead or injured, and resources consumed beyond measure, this once top family on the continent quickly fell to a second-rate force.

Originally, there was hope in the form of Yin Jiuxiao, a promising seed; given time, the Yin family could have made a comeback.

But unexpectedly, the so-called hope of the Yin family fell gravely ill after the family catastrophe. When he finally recovered, he suddenly went blind, and his spiritual power began to decline. No matter how hard he tried, it was futile.

The family was anxious and sought help for him, but no one could determine the cause. They only said he had gone astray in his cultivation and that the sudden calamity had disturbed his mind, leading to a backlash of spiritual power, which was beyond cure.

Soon, the once-promising Yin Jiuxiao’s power regressed to Yellow Level One Star, eventually reaching a point where he couldn’t even summon his innate spiritual marrow, the Nine Heavens Exquisite Cloud Sword.

When the tree falls, the monkeys scatter; the Yin family continued to decline, and Yin Jiuxiao, the once proud son of heaven, endured the hardships of falling from the peak to the valley over the next eight years, suffering endless humiliation.

This bitter life continued until he turned eighteen, when Lin Qingshuang, from the Lin family, came to annul their engagement.

The broken engagement didn’t matter much to Yin Jiuxiao; he had no feelings for Lin Qingshuang, so if they weren’t suitable, they weren’t suitable.

However, the Lin family was arrogant, and their words and actions were beyond what any ordinary person could bear. Not to mention him, even the current Family Head of the Yin family, his uncle, who still remembered their old bond and tried to protect Yin Jiuxiao, could hardly tolerate it and argued for the sake of family honor.

Yet, the already declining Yin family faced retaliation from the Lin family after their resistance.

Lin Zhongtian, who cherished his daughter, tore up the engagement letter during a disagreement, leading to a violent reaction from the engagement contract. Under the Lin family’s influence, the family ancestral hall of the Yin family was destroyed.

In their anger, the Yin family sought an explanation but were met with resistance. Even the Family Head was seriously injured and fell into a coma.

Because of this incident, Yin Jiuxiao was viewed as a disaster by his family. Seizing the opportunity while his uncle, who still protected him, was unconscious, they intentionally drove him out.

Subsequently, he was pushed into an abyss by those who had envied him as a child, a fate that should have left him dead without a trace.

But Yin Jiuxiao did not die.

After years of suffering, he was on the brink of death, nearly shattered to pieces, when he finally awakened the magic bone within him.

It was then that he learned why his mother had never appeared.

He was the child of a Spirit Master and a Demon Cultivator; his missing father had fallen in love with a being from the demonic realm on the other side of the continent.

This was the fundamental reason for his regression in strength and blindness.

The relationship between spirits and demons was like water and fire; they were not meant to merge. The love between his parents had been fraught with difficulties, making it hard for them to be together, and giving birth was immensely perilous.

After giving birth to him, his parents, fearing he wouldn’t be able to withstand it, sealed his magic bone at birth, leaving only his spiritual veins.

Yin’s father took him home and raised him until he was three years old. After confirming that his spiritual foundation was stable, he felt relieved and went alone to seek his lover.

Originally, the plan was that once Yin Jiuxiao cultivated to a certain level, at least to the Earth level, the seal on his magic bone would gradually open.

At that point, he would have the capacity to channel the surging spiritual power and suppress the magic bone that had yet to grow, allowing the two to gradually merge.

His father was a top Spirit Master, and his mother was no ordinary demon cultivator; if everything had gone according to plan, the extraordinarily gifted Yin Jiuxiao should have become a legendary figure in dual cultivation of spirits and demons.

However, the upheaval of demonic energy at the age of seven caused the seal within him to loosen prematurely.

At that time, Yin Jiuxiao was too young to understand what was happening; the two energies suddenly clashed within him, first destroying his eyesight. However, the seal on the magic bone had not completely lifted, and outsiders couldn’t detect it. They could only sense the chaotic energy within him, unprecedented and untreatable.

In reality, he hadn’t regressed in power.

Yin Jiuxiao never gave up on cultivation after turning seven; in fact, he worked even harder. Even though it felt like the spiritual energy he absorbed over the past decade disappeared into thin air upon entering his body,

In reality, half of the energy he absorbed was divided between the magic bone and the sword bone. The two energies, separated by a cracked seal, fought within him, growing stronger and increasingly uncontrollable.

The power indeed existed within him, but each had its own intentions. Young Yin Jiuxiao couldn’t channel a single bit of it, and externally, it appeared as chaotic energy, undetectable, leading to a regression in power, branding him as useless.

Until the brink of death, the hidden fate of his life turned around.

Actually, his parents had considered unexpected situations. Before leaving, Yin’s father disclosed Yin Jiuxiao’s origins in a letter to his grandfather. He also left behind a pair of jade pendants.

These pendants were special spirit artifacts, containing a trace of the original essence of spirit and demon extracted from both of Yin Jiuxiao’s parents, serving as the source of the two energies within him. If he couldn’t control it, he could shatter the pendants, using his parents’ essence as a guide to help him tame the powers inside him.

The fact that the child was the offspring of a Spirit Master and a Demon Cultivator was too significant; naturally, his grandfather kept it a secret. According to the plan, the pendants wouldn’t need to be used this early, as they were intended for critical moments.

But the disaster arrived too swiftly, and his grandfather didn’t anticipate that the seal on Yin Jiuxiao would loosen ahead of time.

He had thought about leaving the pendants for the child, but during the turmoil, the elder he entrusted with the guardianship unexpectedly died, and the pendant left behind by his father was lost.

Amidst the chaos, his grandfather’s words were not clearly passed down. The pendant belonging to his mother did reach Yin Jiuxiao, but it appeared without any trace of spiritual energy, only described as a family heirloom. He had never known its specific purpose and had merely carried it as a keepsake all along.

Until the ancestral hall of the Yin family was destroyed, and in their rage, the Yin family members vented their anger on him, dragging him to bow and apologize amidst the ruins.

Amidst the bloodshed, the pendant he had carried was shattered, and in the destroyed ancestral hall, his grandfather’s memorial plaque also suffered misfortune, crumbling at that moment.

Each family head’s plaque contained a trace of their original essence. Regardless of whether it was his grandfather or father, they were of the same origin as Yin Jiuxiao’s spiritual marrow.

Thus, this trace of original power from the plaque replaced the lost pendant, becoming the key to control the powers within his body.

Then, as Yin Jiuxiao absorbed the “key” during his awakening, he was cast into the abyss of the Wind-Blowing Cliff by his kin.

Amidst the compounded disasters, he underwent the entire process of destruction and rebirth at the Wind-Blowing Cliff, as if being shattered and reassembled.

In the midst of suffering, Yin Jiuxiao found a way to control the spiritual and demonic powers within him, and then it was as if he had been reborn from the depths of hell, crawling back up and returning all the humiliation he had endured one by one.

…

Years later, he became the fearsome Demon Emperor and the Sword Master who could sweep through the world with a single sword. The tale of this fallen genius rising again was recounted by many, evoking both fear and respect.

Unfortunately, when he reached the pinnacle of both the spirit and demon realms in his previous life, he found it dull and attempted to break through the void, only to… fail.

Upon waking, he discovered he had returned to when he was seventeen.

Exactly one year before the Lin family came to annul the engagement.

Surprisingly, a second chance?

Though the timing was a bit late, the decline of the Yin family and the regression of their strength had already occurred, and there was no turning back.

However, at this time, how could Yin Jiuxiao possibly continue living the same life as in his previous existence?

There were far too many plans he could make and wanted to execute.
