Beast Taming: I gained the talent of a spirit pet.

Chapter 529 Thunder Bead!

Gu Yuan had exceptional eyesight; although the light inside the Yin Sha Cave was dim, it couldn't obstruct his vision, so Gu Yuan strode directly into the depths.

Gu Yuan could sense that wisps of Yin energy were now permeating the surroundings.

These yin and evil energies are cold and icy in nature, and some even contain traces of demonic energy, yin energy, and death energy.

If an ordinary cultivator were here, they probably wouldn't last long, because the nature of this Yin energy is special, and even ordinary supernatural powers and spells cannot stop its erosion.

Over time, there is often a risk of the foundation being contaminated.

Unless one is a Golden Core cultivator, it is not possible to use one's powerful magic to create various protective measures and penetrate deep into the Yin Sha Cave.

As for Gu Yuan, he didn't care at all.

Despite the surrounding malevolent energy assaulting his body, it was firmly blocked by his powerful physique.

Gu Yuan didn't even use any protective supernatural powers or magical treasures; he simply relied on his physical strength to ignore the dangerous Yin energy around him.

As they went deeper, Gu Yuan felt the surrounding temperature begin to drop.

Even on the sides of the cave, traces of blackish-gray transparent frost began to appear.

Furthermore, as he went deeper, Gu Yuan also saw some skeletons appearing on the ground. Most of them were not rotten, but frozen into ice blocks, which were extremely hard.

Even some magical artifacts were scattered on the ground. Among them were some intact artifacts, but due to the invasion of Yin energy, the restrictions inside these artifacts had long been corroded away, leaving only a fragile texture. They would crumble into powder with just a light touch.

Gu Yuan remained unmoved and continued to delve deeper.

In addition, the area of ​​the surrounding caves was also slowly expanding. After Gu Yuan went deep underground for about tens of miles, the originally long and narrow cave had become a huge underground cave.

The depths were dark and deep, unfathomable, and within them, one could vaguely see some ghostly figures appearing and disappearing.

Before long, the view suddenly opened up, revealing a huge underground cave that seemed to stretch to the horizon.

Inside the cave, various shades of black, gray, dark gray, blackish red, dark red, and grayish white yin energy intertwined and surged, permeating everywhere.

These malevolent energies vary greatly in nature, some are gentle, some are cold, some are filled with bloody and chilling properties, and some are eerie and fiery.

Gu Yuan could already see that there were other cultivators scattered around, each using their secret techniques to collect various kinds of Yin energy.

In some places, the Yin energy is so strong that the accumulated Yin liquid forms puddles or even pools on the ground.

These pools are quite dangerous. Even if top-grade spiritual materials such as refined gold and iron mother fall into them, they would probably be corroded into a pile of scrap iron in no time.

Gu Yuan searched around and finally came to a pool.

Yes, the water in this pool is dark blue-black, and its surface exudes a deep and cold aura.

This pool is clearly formed from the condensation of Xuanming True Qi. It looks like nothing special, but in reality, every wisp of Xuanming True Qi contains a large amount of cold and evil energy. This evil energy is heavy and cold, like the eternal ice in the depths of the Netherworld, carrying a terrifying power that can freeze one's soul!
Gu Yuan pondered for a moment, then released a wisp of magical power, probing into the Xuanming True Fiend Pool and drawing out a wisp of true water.

The true water formed by the convergence of Xuanming True Evil was extremely terrifying. Even though Gu Yuan's own Taiyuan magic power was extremely refined and pure, and of very high quality, he was actually showing signs of being frozen. Only by continuously outputting magic power could Gu Yuan maintain it.

Once this stream of true water bursts forth, it can easily freeze a mountain into a block of ice!
Then, Gu Yuan flicked his finger, releasing another bolt of dark purple chaotic lightning.

The essence of Xuanming True Fiend is extremely high, and it is one of the best quality and most extreme types of earthly fiend energy in this Yin Fiend Cave. Therefore, once its power is activated, its power will be enormous!

Especially when it is refined into a thunder pearl, its power is even greater!
That's right, Gu Yuan came here to refine some Xuanming Thunder Pearls.

Killing Xiu Daozhen was no easy task, especially without revealing one's identity and methods, which made it even more difficult.

Fortunately, Gu Yuan didn't have to take direct action; instead, he chose to resolve the matter through strategy.

Therefore, he planned to refine some thunder beads so that he could use Xiu Yanqing's identity to make a move at a crucial moment.

Thunder beads are formed by condensing explosive lightning or mixed with malevolent energy into a single bead using secret techniques. This stabilizes the bead's properties and greatly enhances its power.

Gu Yuan came here precisely to do just that.

He was proficient in the Five Elements Divine Thunder, Purple Heaven Divine Thunder, Chaos Divine Thunder, and so on, and his mastery of thunder magic was unparalleled.

Although fusing it with the Xuanming True Fiend and refining it into a Thunder Pearl is very difficult, it is actually entirely possible for Gu Yuan to do so.

Under Gu Yuan's control, the lightning enveloped the true water condensed from the Xuanming True Fiend and began to dissipate the various explosive energies within it.

After the explosive energy was completely dissipated, Gu Yuan used a secret technique to fuse the remaining essence water with the lightning.

Before long, a jet-black lightning bead the size of a finger appeared in Gu Yuan's hand.

This thunder bead has no visible surface, only some faint, fine lines that are barely discernible.

However, Gu Yuan could sense that immense power lurked within, existing in a strange state that appeared stable but was actually prone to erupting.

With just a little guidance, its power will erupt instantly. It seems somewhat similar to the gunpowder in Gu Yuan's previous life, but in reality, its power is incomparable.

After storing the Thunder Pearl, Gu Yuan continued his work, once again using his magic to draw out a wisp of Xuanming True Fiend Water, and then continued refining it.

As a result, Gu Yuan's movements became more and more skilled, and the speed at which he refined the thunder pearls also increased. Nine days later, Gu Yuan had already refined more than six hundred thunder pearls.

Any one of these Thunder Pearls could probably fetch thousands or even tens of thousands of spirit stones.

Don't be fooled by how easily Gu Yuan could refine the Thunder Pearl; the main reason is his profound cultivation and mastery of powerful thunder magic, which makes the process much easier.

Furthermore, in a harsh environment like the Yin Sha Cave, even a Golden Core cultivator cannot last long. Even with the protection of magical treasures, they can only hold out for two or three days at most.

If you're not careful, you might even be invaded and corrupted by the Yin energy, causing damage to your magical power.

Furthermore, even if someone is proficient in thunder magic and wants to refine a thunder pearl, it may take three to five days to successfully refine one.
