Two months later.

In an unremarkable cave three thousand kilometers outside of Kyoto, Chu Xiu sat cross-legged.

His eyes were tightly shut, and a rare sheen of sweat formed on his forehead.

In front of him, a bronze cauldron as tall as two people hovered, carved with ancient patterns.

Curiously, around the imposing cauldron, statues of the Cyan Dragon, Black Tortoise, White Tiger, and Vermilion Bird stood, lifelike as if recreating the ancient divine beasts.

With the continuous refining of the Profound Fire, the details on the cauldron became clearer, and the vastness of the power on the cauldron grew more magnificent.

Finally, as if reaching a critical point, with a light exclamation from Chu Xiu, a mighty force radiated from the cauldron!

"It finally succeeded."

Chu Xiu exhaled a long breath and looked at the cauldron. Soon, a look of surprise appeared on his face!

Upper Three Grades!

With the enhancement of Perfect Refining and the vast resources Chu Xiu collected, the quality of the Four Symbols Yin Yang Furnace in front of him reached the Upper Grade level!

Though it’s just the third of the Upper Three Grades, compared to the Middle Grade, it’s a qualitative leap!

"With this third-grade Four Symbols Yin Yang Furnace, my success rate in refining any artifacts will skyrocket! And the quality will be better, with stronger added Power of the Four Symbols!"

Chu Xiu could no longer hide the joy on his face.

He cast several techniques, and eight dark cyan array flags floated around the Four Symbols Yin Yang Furnace.

In the past two months, he not only refined the Four Symbols Yin Yang Furnace but also raised the level of the Eight Desolates Nether Fire Array.

Much to Chu Xiu’s delight, this equipment also very fortunately reached the third grade!

The Upper Three Grades’ [Eight Desolates Nether Fire Array], according to the records in the inheritance, is something that only top-tier cultivators in the Golden Core and Nascent Soul stages can refine, after collecting countless heavenly materials and treasures.

Most Foundation Establishment demon cultivators only use the Lower Three Grades to refine some dharma artifacts and spiritual artifacts in exchange for cultivation resources, and only a few well-connected inner disciples can refine the Middle Fourth Grade.

However, this was expected. With a bug-level SSS Talent like [Perfect Refining], he is akin to those top Artifact Refining masters whose Divine Thoughts can cover a continent, and whose computational ability surpasses supercomputers.

As long as the materials are qualified, he can refine perfect results!

"However, it will be difficult to continue upgrading to the second grade or even the first grade in the future."

"It will require not only upgrading materials but also time to nurture the spirituality."

Whether it’s the [Eight Desolates Nether Fire Array] or the [Four Symbols Yin Yang Furnace], both will gradually nurture spirituality over long-term refining and use.

According to the inheritance, there was a top Artifact Refining master in the Core Formation Realm who didn’t upgrade the [Four Symbols Yin Yang Furnace] for five hundred years, only nurturing it day after day, and one day after refining an artifact, the [Four Symbols Yin Yang Furnace] transformed from the third grade to the second grade.

"It sounds like an Awakened leveling up through experience, and the refining of artifacts is the upgrade method for the [Four Symbols Yin Yang Furnace] and the [Eight Desolates Nether Fire Array]."

Thinking of this, Chu Xiu couldn’t wait to experiment.

Although he didn’t have the materials for refining artifacts, he had gathered the materials for refining three pieces of [Legendary] equipment!

Soon, materials were thrown into the [Four Symbols Yin Yang Furnace], and as the [Legendary Equipment Blueprint] flew into the furnace, the shape of a pair of gloves gradually took form.

In the data-driven Abyss World, blueprints are no longer [knowledge] but merely one-time use [consumpables]. The benefit, of course, is that you don’t need an Artifact Refining profession to refine them.

However, without the Artifact Refining profession and related equipment, relying solely on the blueprint’s own power would have a ridiculously low success rate, and even with [Perfect Refining], Chu Xiu would probably only manage to produce a defective product.

The role of the Artifact Refining profession is to increase the refining probability and to additionally enhance attributes!

In Chu Xiu’s expectant gaze, in less than two days, a brand new equipment appeared before him. 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

[Secret Silver Spider Mother Gloves: General Tier Legend, Energy Level +240, greatly increases the spell power of the caster and provides a Magic Shield with a Shield Value of 1500, with added Demonization and Vermilion Bird Power.]

[Demonization: Shield Value is increased by an additional 500, but incurs self-demonization erosion by +5.5.]

[Vermilion Bird: Releases an additional three firebirds with any spell, with the power of the firebirds depending on the Mana consumed.]

A legendary equipment for the Mage profession, something Chu Xiu could hardly use; even though the shield was somewhat useful, the value is too weak, just an attached but useless feature, and it’s only at the General Tier.

In fact, all three of the [Legendary Equipment Blueprints] are at General Tier; there’s no helping it. Even though the trials Chu Xiu participated in were almost close to Heroic Spirit in difficulty, the tier was still General, and the extra rewards would only be General Tier.

Fortunately, that piece of [Mythical] equipment is at Heroic Spirit Tier, because the lowest tier for Mythical equipment is also Heroic Spirit.

Another good news is that the other two pieces of equipment are more or less useful, so Chu Xiu used this least useful one to test the waters.

After mastering the methods of the Duo Bao Demon Venerable’s lineage, he immediately proceeded with refining without pause.

Three days later, the other two Legends also came off the line.

[Skywalker’s Boots: General Tier Legend, All Attributes +55, allows the user to hover in flight, provides additional thrust, with Demonization further enhancing thrust, and comes with Cyan Dragon Power, which can manipulate wind and thunder to enhance speed.]

[Meteor Heavy Sword: General Tier Legend, Constitution +200, comes with additional ’Armor Piercing’ and ’Giant Strength’ traits, gains ’Explosion’ trait after Demonization, with added Black Tortoise Power, further enhancing the basic attributes of the heavy sword.]
