Dugu Bo did not slow down along the way.
Fortunately, with the help of three Title Douluos, the group moved at incredible speed and arrived near the Ice and Fire Yin-Yang Well in the blink of an eye.
Within the hidden valley, clouds and mist swirled, making it seem cut off from the outside world.
The moment everyone entered the valley, they sensed a unique aura.
It carried the stifling heat of a rainy summer day.
Following behind Dugu Bo, they quickened their pace and soon spotted a strange lake in the valley.
The lake lay quietly at the center of the valley, its waters divided into two utterly different colors.
One half was as clear and crystalline as ice, radiating bone-piercing cold.
The other was like molten lava, boiling with scorching heat.
The two completely opposing forces intertwined without interfering with one another, strangely forming a delicate balance.
Cold and hot air mingled above the lake, forming a thin layer of mist that sometimes condensed into ice crystals and sometimes rose as vapor.
The surrounding vegetation also seemed to have become somewhat unusual under the influence of this strange environment.
The plants near the Cold Pool were covered in a thin layer of frost and snow.
Meanwhile, the plants near the scorching side glowed crimson all over, as though they could burst into flames at any moment.
Such a wondrous sight left everyone staring in stunned silence.
Among the group, only Dugu Bo and Ye Ruilin remained relatively calm.
As the earliest discoverer of the Ice and Fire Yin-Yang Well, Dugu Bo had long since become intimately familiar with this place.
Ye Ruilin had memories from his past life. Though he had never seen it in person, he still remembered it somewhat.
"What exactly is this place? How could it possess such a strange lake?"
Ning Rongrong stepped forward.
Standing at the boundary in the middle of the lake, she could clearly feel a peculiar aura, carrying both the biting chill of ice and snow and the searing heat of flames.
The two forces intertwined before her.
"The unique environment here allows the plants to grow far faster than they do outside."
"Do you see that Red Snow Spirit Mushroom by your feet? It has only grown for a few decades, yet it already possesses the medicinal potency of a hundred-year herb."
Dugu Bo stepped forward and introduced the Ice and Fire Yin-Yang Well as casually as if discussing household matters.
"More importantly, it not only accelerates plant growth far beyond the outside world, but can also cause plants to mutate, producing many rare immortal herbs and spiritual medicines."
As he said this, Dugu Bo's eyes gleamed with fervor.
For someone like him, who understood medicinal properties so well, this place was simply paradise.
"What exactly do you need the Ice and Fire Yin-Yang Well for?"
Returning to the matter at hand, Dugu Bo immediately looked at Ye Ruilin.
As he looked at the rare immortal herbs growing all around the Ice and Fire Yin-Yang Well, a flash of pain crossed his eyes.
It was fine. These herbs would eventually grow back.
As long as the Ice and Fire Yin-Yang Well's power remained, immortal herbs were only temporary losses.
Dugu Bo consoled himself inwardly.
Ye Ruilin surveyed the rare immortal herbs growing around them, then headed toward the central area.
Since he had come here, he naturally needed to find an immortal herb suited to everyone.
"Frost-Flame Twin Flower, twin blossoms growing from one stalk. One is like an ice crystal, the other like a flame. It contains both extreme cold and blazing heat. Not bad."
"Ah, this Red Snow Spirit Mushroom is good too. After consuming it, one can greatly enhance vitality, repair damaged meridians and Soul Power, and even strengthen perception."
With a single sweep of his gaze, Ye Ruilin found several immortal herbs suitable for use later.
His target was the lake itself, but before entering it, he wanted Old Wu to complete his Martial Soul Evolution first.
Thinking of Old Wu's Blazing Demon Dog Martial Soul—
Ye Ruilin slowly walked toward the fire-element region.
Countless immortal herbs bloomed with their own charm, radiating a unique aura.
After only one glance, Ye Ruilin's attention was immediately captured by an immortal herb.
"Sun-Swallowing Flame Heart Lotus!"
Ye Ruilin had not expected such an immortal herb to grow here.
The Sun-Swallowing Flame Heart Lotus grew in places of extreme heat. Its lotus leaves were crimson like flames, its petals layered upon one another, and at its center sat a golden lotus seed as dazzling as the sun, radiating extreme heat.
The ultimate fire attribute contained within this immortal herb held the power of the sun. It could temper fire-attribute Martial Souls and bring about a qualitative leap.
If Old Wu's Blazing Demon Dog consumed such an immortal herb, his Martial Soul would very likely undergo an extremely powerful evolution.
"Old Wu, this immortal herb is very suitable for your Martial Soul. After consuming it, it may very well trigger an evolution in your Martial Soul!"
Ye Ruilin immediately called Old Wu over.
Old Wu was not proficient in medicinal knowledge, so he had merely been observing the immortal herbs from afar.
Upon hearing the Young Master's words, he hurried over.
"Evolve my Martial Soul?"
Old Wu crouched down to examine the Sun-Swallowing Flame Heart Lotus before him, excitement flickering in his eyes.
Ever since choosing to follow the Young Master, Old Wu had never doubted anything Ye Ruilin said.
Since the Young Master said this immortal herb could help evolve his Martial Soul, then it would certainly allow his Martial Soul to evolve.
"Old Wu, consume it here directly. The environment here is also very suitable."
Ye Ruilin smiled and urged Old Wu to consume it quickly.
However, Old Wu hesitantly glanced at Dugu Bo behind him.
"Young Master, if I begin consuming it, I will certainly enter seclusion and be unable to protect you."
Old Wu was somewhat reluctant.
He could not expose the Young Master to danger for his own sake.
He did not trust those two people from the Seven Treasure Glazed Tile Sect.
If anything truly happened, it would be too late to say anything then.
"Don't worry. With Sword Douluo and Bone Douluo here, nothing will happen to me."
Ye Ruilin looked toward Sword Douluo and Bone Douluo, signaling Old Wu to rest assured.
Sword Douluo glanced at Old Wu's hesitant expression.
"Just consume it without worry. With me here, no one will dare harm your Young Master."
Old Wu still trusted Sword Douluo's strength.
His gaze flickered for a moment, but under Ye Ruilin's urging, he ultimately agreed.
Old Wu walked toward the Sun-Swallowing Flame Heart Lotus, sat cross-legged by the lake, and carefully plucked the golden lotus seed.
The instant the lotus seed touched his hand, a scorching force surged into his body, as if a ball of flame were burning through his meridians.
The fire was incomparably hot, and fine beads of sweat instantly formed across Old Wu's forehead.
The moment the lotus seed entered his mouth, it transformed into a blazing torrent that swept through his entire body in the blink of an eye.
Old Wu felt as though his body had been ignited. Every inch of his skin burned, and every meridian was being tempered.
He tightly shut his eyes and circulated his Soul Power with all his strength, guiding that searing force through his body.
Until his body was gradually enveloped in a layer of crimson light.
From afar, Old Wu had already been wrapped within that red radiance, making it impossible to see inside.
Ma Hongjun tried to approach Old Wu.
But the moment he drew near, he felt the scorching heat in the surroundings.
Even the surrounding air seemed to be warped and distorted by the burning force.
"This power is way too terrifying!"
Ma Hongjun immediately retreated several steps in alarm, moving away from Old Wu's area.
Even with his top-tier fire-attribute Martial Soul, he could barely endure that force.
"The Sun-Swallowing Flame Heart Lotus is extremely suitable for Old Wu's Martial Soul. If everything goes smoothly, Old Wu's Martial Soul should be able to evolve into a top-tier fire-attribute Martial Soul."
Ye Ruilin spoke, somewhat looking forward to Old Wu's new Martial Soul.
"Boss, Boss, take a look and see which one suits me. Find one for me too."
Ma Hongjun immediately crowded up beside Ye Ruilin.
"Brother Ye, I want one too."
Unwilling to be outdone, Ning Rongrong immediately squeezed Ma Hongjun aside and hugged Ye Ruilin's arm.
Ma Hongjun rubbed his nose, too embarrassed to argue with a little girl.
"Don't worry, all of you will get one. I'll find immortal herbs suited to each of your Martial Souls."
Ye Ruilin said with amusement.
He remembered that Tang San had originally given Ma Hongjun a Cockscomb Phoenix Sunflower.
It had mainly been used to remove the Evil Fire within Ma Hongjun's Martial Soul and make it purer.
Although gaining the evolution had made his Soul Power purer and greatly improved his combat strength, it was not a good solution.
The Evil Fire affected Ma Hongjun's body, but it was also a unique ability.
Removing it was the lowest-grade method.
Now, Ma Hongjun no longer needed to worry about the Evil Fire in his body at all.
As he considered the matter while searching, he soon found a suitable target.
Nirvana Fire Phoenix Flower, a fire-attribute immortal herb. Its blossom resembled a phoenix spreading its wings and contained extremely powerful fire-attribute energy.
"Hong Jun, this immortal herb is quite suitable for you."
"After consuming it, it can greatly increase your fire-attribute Soul Power. It can also purify the Soul Power within your body, perhaps making your Evil Fire even more tyrannical."
Ye Ruilin plucked the Nirvana Fire Phoenix Flower and handed it to Ma Hongjun.
"Thanks, Boss!"
With a smooth slide, Ma Hongjun's figure swiftly shot over to Ye Ruilin's side before he hurriedly stopped.
He eagerly took the Nirvana Fire Phoenix Flower from Ye Ruilin's hand and carefully examined it in his palm.
"This little thing actually looks pretty nice."
The tiny flower resembled a miniature phoenix soaring with outspread wings, its petals trembling like phoenix feathers.
He was clearly all about appearances.
"The important thing is its effect. It is extremely suitable for your Martial Soul."
Ye Ruilin shot Ma Hongjun an annoyed look.
Ma Hongjun gave a foolish chuckle, looked around, and immediately found a spot to consume it.
The little girl pouted as she came to Ye Ruilin's side.
That resentful look made goosebumps rise all over Ye Ruilin's body.
"Don't rush, don't rush. We'll take them one at a time."
"There are so many immortal herbs here. There will definitely be one suited to you."
"I only happened to find one suitable for Hong Jun first."
Ye Ruilin explained.
After his explanation, Ning Rongrong finally broke into a smile.
"I knew Brother Ye treats me the best. He only happened to find one suitable for him first."
Then she gave a soft snort in Ma Hongjun's direction.
Ye Ruilin shook his head helplessly.
