"Buzz!"
As soon as Ziyue thought about it, the North Sea Flying Sword in the air immediately began to vibrate.
Then under his control, it produced a huge suction force.
Then, all the spiritual materials around, the essence of magic treasures, the essence of iron and stone, the creation, and the spiritual light were all attracted and poured into the flying sword.
Accompanied by the sound of the flying sword!
With the influx of the essence of various materials, the power of the flying sword began to increase.
"Sure enough, with the increase of my strength, the level of my natal magic treasure finally began to improve.
Unlike before, because my realm was only at the peak of the Divine Realm, the level of my natal magic treasure could only be upgraded to the level of the best magic treasure. "
Ziyue relaxed slightly and continued to urge the flying sword to devour the essence of various materials with all his strength.
As the flying sword continued to devour, the spiritual light of the piles of materials on the ground dimmed at a speed visible to the naked eye. The iron and stone also decayed, and even the broken and complete magical treasures had their essence sucked dry.
As time went by, the piles of materials gradually collapsed and turned into ordinary things, dust …
Seeing this, Ziyue's expression didn't change. With a wave of his hand, he transferred all these things with weak spiritual Qi into the North Sea Cave.
Then with another wave of his hand, another pile of materials piled up around him.
After one pile, another pile.
Under the piling of countless materials, a sense of heaviness was vaguely produced on the flying sword.
"Buzz!"
"Buzz!"
"Buzz!"
With the violent tremor of the flying sword.
With the mind connection, Ziyue immediately felt that his flying sword was smoother, heavier, and more powerful.
"It has been upgraded!
After constantly devouring the essence of various materials and magic treasures, the flying sword has finally been upgraded from the level of the best magic treasure to the level of the Gold Core. "
Ziyue's eyes immediately lit up.
He clearly felt the power of the North Sea Flying Sword at this time.
This kind of power was ten times stronger than before, and there was a kind of transcendent Taoist Connotation.
It seemed that good fortune came from the heart.
Ziyue's heart suddenly moved, and then he reached out and quickly sketched in the void.
"Buzz …"
Soon, the words of the Great Dao began to take shape in the void.
These characters of the Great Dao naturally contained the Great Dao of Heaven and Earth. They were characters created by an ancient almighty after comprehending the Great Dao of Heaven and Earth. They could not be contained on paper or jade slips.
At this moment, as he drew, the void trembled, and ripples spread out in all directions.
If not for his Jindan essence maintaining it, it would have dissipated very quickly.
These words of the Great Dao quickly took shape under Ziyue's writing. Then, he pointed at them.
Chi!
Chi!
Chi!
…
A total of 108 characters of the Great Dao rushed into the Darknorth Flying Sword like a brand.
Instantly, Ziyue's Dharma treasure, which was originally formed by the Dao Accumulation of Heaven and Earth, gained a sense of liveliness and vitality.
It was as if there was an additional layer of fortune on top of this magical treasure.
Even if the magic treasure itself was standing still, there would be wisps of spiritual energy faintly pouring into the flying sword like birds flying into flames.
It was as if it had the ability to 'breathe', and was actually taking in and exhaling Spirit Qi on its own.
"Spiritual intelligence.
This is the Dharma treasure giving birth to spiritual intelligence. "
Ziyue's face immediately revealed a look of excitement.
A natal Dharma treasure was innately close to the cultivator. Naturally, it was intimately close to the cultivator and could be easily controlled by the cultivator.
However, even a natal Dharma treasure rarely gave birth to spiritual intelligence.
This was because spiritual intelligence was equivalent to a Dharma treasure already having 'breathing' and 'life'. It could grow on its own, take in and exhale Spirit Qi of Heaven and Earth, and devour the vitality of various spiritual objects … After a long period of time, it could even advance on its own and increase its grade.
And for a Dharma treasure with this characteristic, even if its original owner died and there was no cultivator to support it, as long as the Dharma treasure itself was not damaged midway, its spirituality was not lost, and its vitality was not extinguished, it would definitely successfully break through the grade limit and step into the ranks of Numinous Treasures.
In other words, even if Ziyue's natal Dharma treasure had only just given birth to spiritual intelligence and had a little bit of spiritual light, it already had the conditions to become a Numinous Treasure.
The qualities of a Numinous Treasure.
The Darknorth Flying Sword already had the qualities of a Numinous Treasure.
One had to know that above Golden Core treasures, there were Essence Soul treasures, and above Essence Soul treasures were Numinous Treasures.
Even if this flying sword was thousands of miles away from becoming a Numinous Treasure, it still needed countless resources and countless years of accumulation.
However, just this slight possibility made Ziyue's natal Dharma treasure become extraordinary.
Its value was ten times or a hundred times that of an ordinary Golden Core treasure.
In the eyes of many sects, it was even a kind of cornerstone treasure that could be passed down for eternity.
The legacy of a sect was originally calculated in tens of thousands of years.
Countless years of accumulation and resources would definitely allow it to advance to a Numinous Treasure.
Time and resources were not a problem at all for a sect with a long heritage.
"I didn't expect that my move of good fortune would give my natal Flying Sword another layer of fortune."
Ziyue was really pleasantly surprised.
Silently turning his spirit consciousness, the flying sword suddenly trembled.
Chi!
It quickly disappeared on the spot.
Even with Ziyue's naked eye, he could only vaguely see a silver flash and traces in the void, but it was difficult to capture the flying sword's trajectory.
"So fast!"
Ziyue was slightly surprised.
He had seen others use Golden Core treasures to attack, and there was no lack of them using their natal Flying Swords.
Some Golden Core treasures had even reached the level of middle-grade Golden Core treasures, or even superior-grade Golden Core treasures.
But in terms of speed, they were far inferior to his Darknorth Flying Sword.
As for power …
Ziyue's gaze fell on a row of test gems in the cultivation courtyard.
This immortal-grade cultivation courtyard was originally a place for Golden Core experts to cultivate.
Naturally, there were also things for cultivators to test their offensive power.
And these test gems were one of them.
The test gems were incomparably hard and had the ability to self-repair, they could be called a great treasure.
The only pity was that they could not be used to refine weapons, but were most suitable for testing the offensive power of cultivators.
There were a total of 12 test gems in a row, corresponding to the 12 levels of Golden Core experts.
For example, passing through a test gem meant that the cultivator had the offensive power of the third level of the early Golden Core stage. Passing through two in a row meant that the cultivator had the offensive power of the second level of the Golden Core stage, and passing through three meant that the cultivator had the offensive power of the third level of the Golden Core stage.
When it came to the fourth, the cultivator had the offensive power of the third level of the middle Golden Core stage.
And so on.
If one could penetrate all 12 test gems in one go, it meant that the cultivator had the offensive power of the Emperor level.
In the entire Cloud Piercing Mountain Range, only the Dream Immortal King was known to have done this.
