Han Yu remained alert, ready to respond if anything went wrong. This was the most volatile stage of the process. Many Jiangshi turned berserk at this point, driven by unstable energy or flawed formation structures.

This one did not.

The Jiangshi rose from the pool in a controlled manner. Its movements were steady, deliberate, and free of the chaotic aggression typically seen in newly formed undead.

It turned its gaze toward Han Yu.

Then, just like Xinren, it knelt.

"Master," it said.

Han Yu's expression did not change, yet a flicker of satisfaction passed through his eyes.

The behavior was consistent.

The intelligence was present.

He proceeded with testing immediately.

Commands were issued.

Movements were executed.

The Jiangshi followed instructions with precision, demonstrating an understanding that far exceeded its expected level. Even when given more complex tasks, it adapted and completed them correctly.

Han Yu observed everything carefully, noting every detail.

In terms of strength, this Jiangshi differed from Xinren. Its body was not as durable, nor as powerful. However, it still exceeded the standard for its tier.

Approximately fifty percent stronger than a typical Bronze Skin Jiangshi.

Not enough to reach Iron Skin level.

More than enough to redefine its classification.

Han Yu completed his tests and stepped back.

His mind worked rapidly, analyzing the results.

The process was repeatable.

The outcome was stable.

The improvements were consistent.

He had achieved something significant.

"A new method," he said quietly.

Not just refinement but a total evolution.

He looked at the two Jiangshi standing before him.

One born from a cultivator's body.

The other from a mortal.

Both carrying intelligence.

Both bound by Trust.

Both under his control.

Han Yu allowed himself a faint smile.

"This is only the beginning."

Han Yu did not stop after confirming the success of his second experiment. If anything, the results only sharpened his focus.

One successful replication was promising, yet it did not prove consistency across variations. What he needed was volume, variation, and controlled comparison. Only then could he truly understand the limits and potential of what he had discovered.

Thus began a period of relentless creation.

Within the confines of his workshop, corpses were processed one after another. Some were mortals, some were low level cultivators, and a few were stronger bodies he had preserved for higher grade attempts.

Han Yu adjusted the specifications with each creation. He altered the number of curse cores, changed the density of blood used in nurturing, modified the rune structures, and even varied the timing of the Eight Emotions infusion.

Despite all these differences, one factor remained constant.

Trust.

Each Jiangshi received a wisp of Green Trust Energy at the precise moment when their transformation stabilized. Han Yu observed every instance with meticulous attention, noting the formation of the Dao Script symbol, the extension of green tendrils, and the integration with the internal cores.

The results were remarkably consistent.

Every Jiangshi that successfully formed under this method displayed the same fundamental behavior. Upon awakening, they showed immediate recognition of Han Yu. They did not enter a berserk state. They did not resist control. Instead, they acknowledged him with a natural obedience that felt less like compulsion and more like acceptance.

"Master," they would say.

Every single one.

Their intelligence also remained above standard. While their capabilities varied depending on the body and materials used, their baseline awareness remained intact. They could follow complex instructions, adapt to unfamiliar situations, and even exhibit simple forms of reasoning.

The only differences lay in their strength and durability.

Some reached the level of enhanced Bronze Skin Jiangshi. Others approached Iron Skin. A few exceptional cases even showed signs of evolving beyond their initial classification, though Han Yu chose to suppress those changes for the sake of stability.

After several days of continuous work, Han Yu stepped back and surveyed his creations.

A small group of Jiangshi stood before him, silent and motionless, awaiting his command.

He folded his arms and considered their nature.

"These cannot be treated as ordinary Jiangshi anymore," he said quietly.

They were fundamentally different.

A new classification was needed.

Han Yu thought for a moment, then nodded to himself.

"Ju Series Jiangshi," he declared.

The name carried both authority and intent. These were his creations, born from his methods, shaped by his understanding. They represented a new branch of Jiangshi entirely.

Within this series, he established a further classification.

"Trust based units will be designated as Green Class," he continued.

The color matched the energy that defined them. It was simple, clear, and efficient.

The Jiangshi did not react, yet Han Yu knew they understood on some level. That alone was enough.

With the Trust Energy experiments yielding stable and repeatable results, his attention naturally shifted to the next question.

What about the other emotions?

Han Yu narrowed his eyes slightly.

"If Trust can do this… then what about the rest?"

He did not rush blindly into the more volatile options. Experience had already taught him that not all energies were equal in stability.

He chose the next candidate carefully.

Joy.

The Yellow Joy Energy was, in his understanding, among the safer options. It carried warmth, positivity, and outward expression. If any emotion could produce a stable variation similar to Trust, it would be this one.

Han Yu prepared a new corpse.

A simple mortal body once again.

The process repeated.

Purification.

Rune inscription.

Stabilization in the herbal pool.

Insertion of the Reanimation curse core.

Blood pool nurturing.

Every step was executed with precision, refined through repetition.

When the time came, Han Yu summoned a wisp of Yellow Joy Energy.

The glow was softer than the green light of Trust, yet it carried a strange liveliness that seemed almost out of place within the cold environment of the workshop.

He guided it into the forming Jiangshi.

Then he waited.

The transformation proceeded without immediate failure, which was already a positive sign. The energy integrated into the Dantian, forming a Dao Script symbol similar in structure to the previous ones, though its shape was different and read Joy.
