Chapter 529 - 528: Thunder Beads
Gu Yuan’s eyesight was incredibly sharp. Although the light in this Yin Sha Cave was dim, it could not block his vision, so Gu Yuan strode directly towards the depths.
Gu Yuan could feel that there were already threads of Yin Sha Qi lingering around.
This Yin Sha Qi was inherently cold and icy, with some containing traces of demonic energy, yin energy, and death energy.
If ordinary cultivators were here, they probably wouldn’t last long at all, because this Yin Sha Qi was of a special nature, and even ordinary divine techniques and magic couldn’t resist the corrosion of this Yin Sha Qi.
Over time, there is often a risk of having one’s foundation polluted.
Unless one were a Golden Core Great Cultivator, who could rely on their abundant mana to cast various protections and venture deep into the Yin Sha Cave.
As for Gu Yuan, he didn’t care at all.
Letting the Yin Sha Qi invade his body, it was firmly blocked by his strong physique.
Gu Yuan didn’t even use any body-protecting divine techniques or magical treasures, relying solely on his physique to ignore the dangerous Yin Sha Qi around him.
As he continued deeper, Gu Yuan felt the temperature around him constantly dropping.
Even the sides of the cave began to show traces of black and gray transparent frost.
Furthermore, as he delved deeper, Gu Yuan saw some skeletons appearing on the ground, most of which had not decayed but were frozen into blocks of ice, extremely hard.
Even some magical artifacts were scattered on the ground, some of which were complete, but due to the invasion of the Yin Sha Qi, the restrictions within these magical artifacts had long been corroded away, leaving only fragile textures that would collapse into powder with a light touch.
Gu Yuan remained unmoved and continued deeper.
In addition, the area of the cave was also slowly expanding. After Gu Yuan had ventured about dozens of miles underground, the originally narrow cave had turned into a massive cavern.
The depths were dark and profound, impossible to see the bottom, with some ghostly figures faintly appearing within.
Soon, the path ahead opened up suddenly, revealing an enormous cavern that seemed nearly boundless.
In the cavern, all sorts of black, gray, black-gray, black-red, dark red, gray-white, and other colors of Yin Sha Qi intertwined and surged, spreading everywhere.
Some of this Yin Sha Qi was mild, some cold, some brimming with a bloody and chilly nature, and some bizarre and scorching, their nature varied widely.
Gu Yuan could already see some other cultivators scattered around, each casting secret techniques to collect the various Yin Sha Qi.
In a few places, the Yin Sha Qi was even too dense, with the accumulated Yin Sha liquid forming puddles or even pools on the ground.
These pools were quite dangerous. Even upper-grade spiritual materials like refined gold iron mother thrown into them wouldn’t last long before being corroded into a pile of scrap metal.
Gu Yuan explored around and finally arrived at the edge of a pool.
Hmm, the water in this pool was blackish-green, exuding a deep and cold aura on its surface.
The pool was clearly formed by the condensation of Xuan Ming True Shade. It appeared unremarkable, but in fact, each wisp of the Xuan Ming True Shade contained a massive amount of cold Qi, heavy and icy, like the unmelting mysterious ice in the Nine Netherworld, carrying a terrifying power capable of freezing even the divine soul completely!
Gu Yuan pondered for a moment and released a wisp of mana, probing into the Xuan Ming True Shade pool to draw out a wisp of True Water.
The True Water gathered from the Xuan Ming True Shade was extremely fearsome. Even Gu Yuan’s supreme and pure Tai Yuan mana, with its high essence, seemed to be at risk of freezing.
Gu Yuan had to continually channel mana to maintain it.
If this wisp of True Water exploded, it could easily freeze an entire mountain into a block of ice!
Then, Gu Yuan flicked his finger and sent out a black-purple Chaotic Thunder Light.
The essence of the Xuan Ming True Shade was of extremely high quality, and it was among the best and most extreme types of earth shade Qi within this Yin Sha Cave, so once its power was unleashed, it would undoubtedly be tremendous!
Especially when refined into Thunder Beads, its power would be even greater!
Indeed, Gu Yuan’s purpose in coming here was precisely to refine some Xuan Ming Thunder Beads.
Killing Xiu Dao Zhen was not an easy task, especially without revealing his identity and methods, which made it significantly more difficult.
Fortunately, Gu Yuan didn’t have to act directly but chose to handle things strategically.
So, he planned to refine some Thunder Beads, which he could use to act under Xiu Yanqing’s identity at critical moments.
Thunder Beads are created by condensing explosive thunder or mixed Gang Sha Qi into a stable Thunder Bead through a secret technique, greatly enhancing its power.
The reason Gu Yuan came here was exactly for this purpose.
He was proficient in Five Elements Divine Thunder, Purple Sky Divine Thunder, Chaos Divine Thunder, and had reached the pinnacle of Thunder Skill mastery.
By integrating it with Xuan Ming True Shade and refining it into Thunder Beads, although challenging, it was entirely feasible for Gu Yuan.
Under Gu Yuan’s control, the Thunder Light wrapped around the wisp of True Water condensed by the Xuan Ming True Shade and began to erode away its explosive Qi.
Once all the explosive Qi had been exhausted, Gu Yuan used a secret technique to merge the remaining pure True Water with the Thunder Light.
Soon, a thumb-sized pitch-black Thunder Bead appeared in Gu Yuan’s hand.
The Thunder Bead appeared ordinary on the surface, with only faint and dense patterns faintly visible.
But Gu Yuan could sense the immense power lurking inside, in a seemingly stable but in fact, easily eruptable, peculiar state.
With just a little guidance, the power within would erupt instantly, resembling the nature of gunpowder from Gu Yuan’s past life but with incomparable might.
Storing the Thunder Bead away, Gu Yuan continued to work, using mana to draw out another wisp of Xuan Ming True Shade True Water, and then continued refining.
Thus, Gu Yuan became increasingly adept, and his speed in refining Thunder Beads grew faster and faster. After nine days, he had already refined over six hundred Thunder Beads.
Any of these Thunder Beads could likely sell for thousands or even tens of thousands of Spirit Stones.
Despite Gu Yuan refining Thunder Beads seemingly effortlessly, it was mainly due to his profound cultivation and his mastery of great divine techniques in Thunder Skill, which made the process notably easier.
Furthermore, in the harsh environment of the Yin Sha Cave, even Golden Core Great Cultivators couldn’t last long. Even with magical treasures for protection, they could only sustain themselves for about two to three days at most here.
One misstep, and their mana could be invaded and corroded by the Yin Sha Qi, causing some damage.
And even if someone proficient in Thunder Skill wanted to refine Thunder Beads, it could take three to five days to successfully refine just one.
