Entering the Ice and Fire Yin-Yang Well

Old Wu gave a light wave of his hand, and the surrounding air instantly detonated under the extreme heat.

The scorching flames swept out like a tidal wave, instantly scorching the ground for dozens of meters into a charred wasteland. The heat waves rolled, causing even the air to distort.

However, Old Wu was well aware that countless immortal herbs grew here. Under the shroud of his soul power, he did not harm any of them.

The phantom of the Sun-Swallowing Heavenly Dog slowly shrank, eventually merging into Old Wu's body.

The moment it vanished, a layer of crimson flame patterns emerged on the surface of Old Wu's skin.

With the energy around him not yet fully dissipated, every step he took left a charred footprint on the ground.

"Young Master!"

Old Wu's voice carried irrepressible excitement.

"My martial soul has completely evolved into a top-tier fire-attribute divine beast martial soul—the Sun-Swallowing Heavenly Dog."

"Not only that, but several of my soul skills have also undergone earth-shaking changes."

He looked at Ye Ruilin, his expression filled with gratitude.

There was a time when he thought reaching the Soul Douluo realm was the limit of his life.

If not for the Young Master bestowing upon him that nine-thousand-year Explosive Flame Mastiff soul bone, helping him break through to the Title Douluo realm, he feared he would never have been able to touch this level.

And now, the Young Master had granted him this opportunity, allowing his martial soul to undergo a qualitative leap.

His original level ninety-one cultivation had now broken through to level ninety-four, and his combat power was far beyond what it had been several times over.

"Not bad."

Ye Ruilin nodded slightly, his expression indifferent.

He had anticipated the evolution of Old Wu's martial soul.

There were not many top-tier fire-attribute canine martial souls.

The Sun-Swallowing Heavenly Dog could be considered one of the most formidable among them.

Off to the side, the expressions of shock on the faces of Sword Douluo and Bone Douluo had yet to fade.

The transformation of a martial soul did not just mean an increase in one's own combat power.

It meant a breakthrough in the ceiling of one's cultivation.

For an ordinary martial soul, no matter how hard one trained, it was difficult to reach the realm of a Title Douluo.

Given the grade of Old Wu's Blazing Demon Dog, had it not been for the help of the soul bone, he likely would never have been able to cross that chasm in his lifetime.

Now, a single immortal herb had allowed Old Wu's martial soul to transform into a top-tier divine beast martial soul.

No one knew how far Old Wu would be able to go in the future.

But one thing was certain: with his martial soul at its current stage, he could easily reach the high-level Douluo tier of level ninety-five and above.

Even Sword Douluo, with his soul power as high as level ninety-six, could not help but feel a jolt in his heart when sensing the aura emanating from Old Wu's martial soul.

Bone Douluo went without saying.

His martial soul was somewhat unique, but it still belonged to the category of beast martial souls.

The Sun-Swallowing Heavenly Dog was in no way inferior to divine beasts like dragons or phoenixes.

Among everyone present, none was more shocked than Dugu Bo.

He had occupied the Ice and Fire Yin-Yang Well for many years, yet he had never glimpsed the true wonders of this treasure land.

He had never known that immortal herbs capable of evolving martial souls grew within the Ice and Fire Yin-Yang Well.

At this very moment, watching Old Wu's domineering and high-spirited appearance, Dugu Bo could not help but feel a surge of regret and jealousy.

Why wasn't it him?

Although his Jade Scale Serpent Emperor martial soul could be considered a top-tier martial soul, it was still a notch below a top-tier divine beast martial soul.

After a hesitant glance at Ye Ruilin, Dugu Bo finally could not hold back and asked, his tone tinged with anxiety.

"Um, little brother, which... which immortal herb do you think is suitable for me?"

"My current soul power is only level ninety-one; it is as difficult as ascending to heaven to improve further at the Title Douluo realm. If you can help me successfully advance, I, Dugu Bo, promise here and now that I will unconditionally fulfill three requests for you in the future, without refusal!"

"What do you think?"

In a short span of time, Dugu Bo's attitude toward Ye Ruilin had shifted from disdain to recognition, and now to anxiety and anticipation.

"Senior Dugu, there is no need to be impatient."

"Once the toxins in your body are cleared, I will naturally gift you an immortal herb to help you break through!"

Ye Ruilin smiled slightly, his tone composed.

He understood that Dugu Bo had taken the bait completely.

He had two reasons for letting Old Wu evolve here.

One was to make Sword Douluo and Bone Douluo realize his capabilities, thereby increasing his importance within the Seven Treasure Glazed Tile Sect.

After all, he still needed to cultivate within the Seven Treasure Glazed Tile Sect for some time at this stage.

During this period, being able to obtain more resources would naturally be excellent.

The other reason concerned Dugu Bo.

What were one or two promises?

What he wanted was for Dugu Bo to acknowledge him as his master completely!

However, given Dugu Bo's temperament, if he were to state his goal directly, it would likely be difficult to achieve.

He could only use a roundabout method, letting Dugu Bo step into his trap one step at a time.

"Is that true?"

Hearing this, a flash of surprise and suspicion crossed Dugu Bo's eyes.

He knew deep down that from the moment he agreed to bring these people to the Ice and Fire Yin-Yang Well, it no longer belonged to him.

Even if this youth were to take away all the immortal herbs within the Ice and Fire Yin-Yang Well, he would have no right to stop him.

Yet, this kid had proactively offered to give him an immortal herb suitable for him, free of charge.

Dugu Bo was both surprised and suspicious.

But with Old Wu's example right before his eyes, even with his doubts, he still wanted to believe the youth's words.

"Are you sure you don't need me to do anything?"

Dugu Bo asked hesitantly.

"No need!"

Ye Ruilin answered decisively.

"Old Wu, since you have successfully completed your evolution, stay here and keep watch."

Ye Ruilin then looked at Old Wu.

"Understood, Young Master."

Old Wu responded respectfully.

Ye Ruilin said no more and began searching for the immortal herbs he might need.

The ice and fire energies of the Ice and Fire Yin-Yang Well were powerful; just in case, Ye Ruilin collected every immortal herb he could use into his spatial ring.

Confirming he was prepared, he walked straight toward the Ice and Fire Yin-Yang Well.

Seeing this, Dugu Bo hurriedly spoke up to stop him.

"Wait! The ice and fire energies within the Ice and Fire Yin-Yang Well are intertwined. If you enter rashly and cannot withstand them, I fear there is a danger of your body exploding!"

Dugu Bo spoke, hoping Ye Ruilin would not take the risk.

Ye Ruilin, however, smiled indifferently.

"Senior, thank you for your kindness."

"What I need right now is precisely these two extreme forces of ice and fire."

Before his words had even faded, he leaped into the Ice and Fire Yin-Yang Well.

The moment he entered, Ye Ruilin felt a force of freezing ice sweep over his entire body.

It felt as if even his soul could not escape this icy power.

Yet, the next second, the icy power within his body rapidly receded, and a scorching flame energy erupted from within, causing his blood to boil and his body to feel as if it were being burned by a raging fire.

Cold sweat instantly covered Ye Ruilin's forehead, and his body began to tremble violently under the impact of these two forces.

The surface of his skin flickered between crimson red and a layer of frost.

Clenching his teeth, relying on his last ounce of strength, he directly circulated the Primordial Art, frantically drawing both forces into his body.

The massive ice and fire energies surged rapidly into him; the scorching flames felt as if they could incinerate everything, and every impact made his meridians ache with an unbearable pain, as if scorched by fire.

Meanwhile, the extreme frost felt like countless ice needles piercing into his bone marrow, bringing a bone-chilling cold.

The massive power was frantically ravaging his body.

Under the influence of these two forces, his body instantly became riddled with holes.

His entire body slowly sank to the bottom of the lake, disappearing from everyone's sight.
