Zhou Jingsong took the Jade Scroll and then took his leave.

In less than half a day’s time, he returned to Zhou Xun’s Cave Mansion. As the Treasure Vault Steward of Tianhan City, he had the authority to allocate the stored Treasures of Heaven and Earth.

Now, with Zhou Xun’s list and authorization, finding the materials naturally went quickly.

Zhou Xun took the materials from Zhou Jingsong’s hands and examined them carefully.

The materials were prepared in double sets, indicating Zhou Jingsong’s thorough consideration, and Zhou Xun was extremely satisfied:

"Not bad!"

After a brief chat, he dismissed the disciple.

Once he left, Zhou Xun took the materials into the Cultivation Room to begin refining his Lifebound Magical Treasure—the Cyan Emperor Seal.

Inside the Cultivation Room,

Zhou Xun sat cross-legged, patting his waist to take out a Tier Three Calming Incense, placing it before him.

With a flick of his fingers, a Qi Force brushed across the incense head, instantly igniting it,

immediately, an indistinct sandalwood scent began to permeate, swirling around Zhou Xun’s nose and then entered it,

upon smelling this aroma, Zhou Xun’s mind instantly settled into tranquility, becoming stable, and his six senses became sharper.

Such is the effect of Tier Three Calming Incense, able to temporarily enhance a Core Formation Cultivator’s six senses, effectively resisting distractions.

It is an excellent item for aiding cultivation.

It was refined from Tier Three High-Grade Calming Grass, extremely rare, which Zhou Xun only discovered in the Treasure Vault after taking over Tianhan City,

this foot-long Calming Incense is priced at ten thousand Spirit Stones,

if it weren’t for refining his Lifebound Magical Treasure, Zhou Xun wouldn’t part with it.

After reaching this tier of Calming Incense, lighting one during Nascent Soul Formation offers some aid against Heart Demons.

Quickly, with the help of the Calming Incense, Zhou Xun swiftly settled his mind, adjusting his Essence, Qi, and Spirit to a peak state before opening his eyes,

his eyes calm as a serene lake, extremely tranquil.

Zhou Xun began to recall the refining process of the Cyan Emperor Seal,

this treasure requires five kinds of Spirit Wood as main materials, mixed for refining, and the higher the grade of the Spirit Wood used, the more powerful the resulting Magical Treasure becomes.

The Cyan Emperor Seal is both offensive and defensive, capable of combining with his Lifebound Spirit Plant, increasing its power by another three parts.

Zhou Xun’s Lifebound Spirit Plant is a Mysterious Lotus Seed, a peculiar existence; thus, the Cyan Emperor Seal is the most suitable Magical Treasure for him.

Going over the entire refining process in his mind again, Zhou Xun began refining.

Zhou Xun formed a spell seal with both hands and took out the Grand Elder Order, slowly injecting Mana into it,

the Token floated up, emitting a Spirit Light that hit the array above the Cave Mansion,

not long after, the entire thirty-six layers of Spiritual Qi began to converge, pouring into Zhou Xun’s Cave Mansion.

Hence, almost visibly, the Spiritual Energy Concentration within the Cave Mansion rapidly increased.

As Tianhan City’s best Cave Mansion, its Spiritual Energy Concentration had already reached Tier Three Top-Grade level, enhanced further by the Spirit Gathering Array,

it directly elevated to Tier Four Level,

even sufficient for a True Monarch Nascent Soul’s use.

Sensing the Cave Mansion’s Spiritual Energy Concentration, Zhou Xun nodded silently, then patted his waist storage bag,

dozens of Spirit Lights fell to the ground, transforming into five exquisite boxes and a small pile of rare materials.

These were precisely for refining the Cyan Emperor Seal.

Looking at the five boxes, Zhou Xun waved his hand, Mana surging from his fingertips, then five strands of Qi Force flew out,

removing all the Sealing Spirit Talismans stuck on the boxes, then opening the lids, revealing the treasures within,

the first box contained a palm-sized, spindle-shaped wood heart resembling jade,

its surface radiating threads of Spirit Charm, extraordinarily superior!

It was the "Jade Wood Heart," known for dispelling illusions,

the second box contained a black piece of wood about four feet long, seemingly ordinary, but its name was the renowned "Nourishing Spirit Wood," of Tier Four level,

items refined with it have the effect of nurturing the Divine Soul and more easily giving birth to the Magical Treasure Spirit, or even an Artifact Spirit, a capability typically belonging to Spirit Treasures alone.

The third box held Tier Four Soul Shocking Wood, capable of intimidating the Divine Soul, akin to Zhou Xun’s Yin Thunder,

the fourth box was a three-foot-long, strange Spirit Wood resembling both gold and wood,

its cross-section had faint golden cloud patterns.

This was the Tier Four High-Grade "Profound Gold Wood," dubbed the Crystal Refiner of wood, and it is the most resilient Spirit Wood below Tier Five!

As for the last box, it contained the "Spirit Void Divine Bamboo" he acquired from the Secret Vault.

These five Spirit Woods were exceedingly rare treasures in the Cultivation Realm, even a True Monarch Nascent Soul would be envious upon seeing them.

The Cyan Emperor Seal, refined with them as main materials, would possess unimaginable power.

With a serious expression, Zhou Xun gazed at these Spirit Woods, took a deep breath, and then extended a finger towards the "Jade Wood Heart" in the first box, lightly pointing at it.

At once, the palm-sized wood heart, like jade, floated out of the box, hovering motionless in front of his chest.

Zhou Xun, with a solemn look, formed a spell seal with both hands,

the Golden Core in his Dantian suddenly emitted a surge of Cyan Light, passing through the Dantian,

then traces of glowing light appeared on Zhou Xun’s face, gradually manifesting a layer of Cyan Light.

As the Cyan Light intensified, Zhou Xun opened his mouth, a fine thread-like Cyan Pill Fire spewed out, hitting the wood heart in front of him.

"Psst" sounded as the wood heart emitted a faint shadowy light, blocking the Pill Fire,

seeing this, Zhou Xun’s eyes flashed with brilliance,

the Cyan Pill Fire immediately split into several streams, wrapping both the shadowy light and the wood heart itself in Cyan Fire, commencing the lengthy refinement process.

Pill Fire consumes substantial Mana,

but Zhou Xun had prepared in advance; upon releasing the Pill Fire, both hands grabbed two High-Grade Spirit Stones simultaneously, beginning to absorb the Spiritual Qi within,

at the same time, he took out a Tier Three Low-Grade Qi Recovery Pill and swallowed it,

the moment those Elixirs entered his stomach, they transformed into pure medicinal power, refined by Zhou Xun into Mana, then absorbed into the Golden Core within his Dantian,

providing continuous replenishment!

In this manner, Zhou Xun’s Pill Fire continuously refined the wood heart,

two days swiftly passed, and the wood heart’s shadowy light was finally ground away by the Pill Fire, losing its protection, allowing the fire to refine the wood heart’s core.

Another four days went by, showing signs of melting on the wood heart’s surface, certain areas began to faintly shine, oozing countless tiny cyan droplets.

In such a way,

nearly ten days passed, and the entire wood heart was finally purified of impurities, refined into a fist-sized mass of cyan liquid,

appearing extremely viscous!

Seeing this, Zhou Xun smiled slightly, took out a Jade Bottle, placed the liquid inside, keeping it in reserve.

Then Zhou Xun concluded his practice, meditating to regulate his breath,

half a day later, Zhou Xun turned his gaze towards the second wooden box,

repeating the same steps, another ten days of refining transformed it into a liquid mass,

next was the third box, the fourth...
