The Yin-Yang Mirror Drained the Ice and Fire Dragon King

This wait lasted for three days.

Dugu Bo finally left the Sunset Forest, and Ling Yun proceeded with extreme caution, nearly falling into the jaws of soul beasts several times.

There were many soul beasts with unique methods and keen perception.

In particular, the Shadow Leopard, the Ghost Tiger, and the Crypt Demon Spider.

The Shadow Leopard could manipulate dark elements to form a domain-like black mist, and it was naturally suspicious and sensitive; the moment Ling Yun entered its perception range, the dark elements immediately surged.

Fortunately, the Chaos Bead martial soul possessed the ability to traverse space and time. Otherwise, the Shadow Leopard would likely have enjoyed a hearty meal.

The stealth capability of the Chaos Bead was absolutely top-tier, and space-time traversal was merely an instinct.

Every space, every point in time—as long as the Chaos Bead wished to go, it could.

This was the most basic ability of the Chaos Bead martial soul; the consumption was not high, at least not high relative to its effects.

But for his level 15 soul power, it was a bit too much.

Just as the Shadow Leopard was about to strike him, he consumed one-fifth of his soul power and appeared directly three kilometers away.

The Ghost Tiger was even more exaggerated; Ling Yun had only glanced at it, yet in the blink of an eye, the Ghost Tiger was before him, its tiger claws descending without hesitation.

Likewise, Ling Yun activated the spatial ability of the Chaos Bead martial soul and escaped death once again.

To this day, he still couldn't figure out how the Ghost Tiger had discovered him.

The Crypt Demon Spider was a complete "camper," capable of burrowing underground; its tunnels were like a labyrinth, and it could sense any creature walking on the surface above.

This was a "camper" soul beast that sensed targets through vibrations; compared to other spiders, the burrowing Crypt Demon Spider was impossible to guard against.

He still couldn't forget the moment the Crypt Demon Spider suddenly appeared, face-to-face with him; it was simply too terrifying.

Ling Yun shook his head to cast aside these unpleasant memories, his eyes lighting up as he looked at the thick fog ahead, feeling unprecedented excitement.

Protected by the chaos barrier of his Chaos Bead martial soul, he entered the area covered by the thick fog. Along the way, he encountered many soul beast carcasses and some skeletal remains that crumbled at the slightest touch.

The thick fog contained terrifying corrosive toxins.

After traveling a bit further, he sensed a familiar fishy smell; it was the poison formation laid down by Dugu Bo.

Arriving here, he faintly sensed the aura of the Ice and Fire Yin-Yang Well, and without further hesitation, he used spatial traversal.

The positioning was precise; he appeared right beside the Ice and Fire Yin-Yang Well.

This was the bottom of the valley; looking up, the sky was completely invisible, obscured by the thick fog covering this region.

The source of this fog was the spring pool before him, thirty meters in diameter. It wasn't large, but the energy concentration was incredibly exaggerated.

Half of the spring water was crimson, radiating terrifying heat. On the bank of this half, there grew a plant that looked like a cabbage but was entirely red, emitting a terrifying heatwave.

The other half of the spring was milky white, emitting a chill. On its bank grew a medicinal herb with a top that looked like an octagonal white flower, crystal clear and radiating cold air.

The two colors of spring water were like the Yin and Yang fish of a Taiji diagram.

The red was the Scorching Yang Spring, and the milky white was the Extreme Cold Yin Spring.

Where Yin and Yang met, they were clearly demarcated yet exceptionally calm, staying obediently in their own domains.

The line between the milky white and the crimson emitted rolling heat.

Thirty centimeters above the spring water, the cold and hot air currents clashed violently, producing a large amount of water mist that continuously drifted outward.

This process carried rich heaven and earth energy.

The entire valley was filled with these two extreme types of heaven and earth energy: extreme heat and extreme cold.

For plants capable of withstanding this special environment, this was a treasure land in every sense.

It was a treasure land that could accelerate plant growth tenfold.

Growing here for one year was equivalent to ten years in the outside world.

After Dugu Bo discovered the wonders of this place, he transplanted many rare medicinal herbs here, turning it into his private herb garden.

For animals and humans, this place was a death trap; if they couldn't escape in a short time, they would be eroded by the extreme cold and extreme heat energy, eventually exploding and dying.

Everything had its exceptions; for Dugu Bo, these two streams of heaven and earth energy became the best aid for suppressing the toxins in his body.

For him, this place was actually beneficial to his health.

For Ling Yun, it was even friendlier; his Yin-Yang Mirror martial soul had appeared spontaneously, crazily drawing in the two types of heaven and earth energy.

The Yin-Yang Mirror in his mind also took action, leaving Ling Yun's body for the first time and appearing above the Yin-Yang spring eyes.

Immediately after, the Scorching Yang Spring and the Extreme Cold Yin Spring began to rotate violently, and streams of special energy were extracted by the Yin-Yang Mirror.

After a quarter of an hour, the rotation of the Yin and Yang springs slowly stopped, returning to their original state. The Yin-Yang Mirror submerged back into Ling Yun's forehead, appearing deep within his soul.

"What? You drained the divine power of the Ice and Fire Dragon King!"

"The effects of the Ice and Fire Yin-Yang Well won't disappear, will they?"

"..."

"It will only affect the plants' ability to develop sentience? That's fine then!"

After understanding the situation, Ling Yun felt this was actually quite good. In the Douluo Continent series, apart from the current era, whether it was the era of Huo Yuhao ten thousand years later or the era of Tang Wulin twenty thousand years later, these immortal herbs had all developed sentience and become hundred-thousand-year soul beasts.

All of this was related to the source of the Ice and Fire Yin-Yang Well: the Ice Dragon King and the Fire Dragon King.

Now, with the Yin-Yang Mirror absorbing energy like this, those two dragons would likely need to spend another twenty thousand years to recover.

Ling Yun suddenly recalled something else and asked the Yin-Yang Mirror in his mind, "Right, do the Ice and Fire Dragon Kings have spirit bones?"

The answer left him overjoyed; they actually did, and they had been collected by the Yin-Yang Mirror, which was currently absorbing the divine power within them.

Had Ling Yun asked just a few minutes later, the divine power of the spirit bones would have been drained dry.

The Ice Dragon King and the Fire Dragon King were the main forces of the Dragon God War; they were undoubtedly at the level of Main Gods during their lifetimes, and the dragon race was renowned for their physical prowess.

It was quite possible that the two dragons were even stronger than the Sea God.

Spirit bones at the level of divine beasts—could these even be called spirit bones? They were essentially divine bones, and Ling Yun felt as if he had picked them up for free.

"Sea God Set, watch as I shatter you with divine bones!"

Ling Yun did not absorb the spirit bones; instead, he focused his gaze on the glowing plants surrounding him.

The most eye-catching was a large, pink flower rooted on the bank where the two springs intersected.

Each petal of the pink flower was as translucent as crystal, with a stem three feet long and a blossom over a foot wide, devoid of any leaves.

The flower emitted a pale pink light barrier with a diameter of ten meters, centered on itself; the color was so faint that one might overlook it if not looking carefully.

After Ling Yun stepped into the range of the light barrier, he caught a faint, delicate fragrance—it was the Aromatic Silk Beauty.

The Aromatic Silk Beauty itself could not cure poison, but it could neutralize all toxins; no matter what the poison was, once it entered the range of its light barrier, it would inevitably be suppressed.

For those who loved researching toxins, this thing was worth more than a hundred-thousand-year spirit ring.

Following that were the white Octagonal Mysterious Ice Grass and the red Infernal Delicate Apricot on either side of the Yin-Yang springs.

These were the only options for an ordinary person wishing to stay in the Ice and Fire Yin-Yang Well for a long time: consume both immortal herbs and use the water of the Ice and Fire Yin-Yang Well to digest their medicinal power, tempering the body with ice and fire.

Either one alone was a deadly poison to the human body—the cold poison of the Octagonal Mysterious Ice Grass and the fire poison of the Infernal Delicate Apricot.

There was only one way to consume them: after picking both herbs, one had to press them together so they would neutralize each other. The window of time was a mere ten breaths, and they had to be swallowed within that duration.

The harvesting of these immortal herbs was also exceptionally particular; if the method was improper, the medicinal power would be diminished at best, or lost entirely at worst.

The Octagonal Mysterious Ice Grass required a gold or iron tool to harvest, while the Infernal Delicate Apricot required a jade utensil.
