At Last, the Ice and Fire Yin Yang Well—Immortal Herbs! Immortal Herbs!

Whale Rubber could strengthen the body?

Hearing Ye Yu's words, Dugu Bo could hardly believe it.

But setting aside his preconceptions and carefully analyzing things according to what Ye Yu had said...

He realized that Whale Rubber possessed powerful vitality and could indeed strengthen the body.

Logically speaking, there really was no problem with it!

At that moment, Ye Yu continued.

"I plan to use Whale Rubber as the primary ingredient, supplemented by various medicinal herbs rich in life force, as well as cold-natured herbs capable of suppressing Whale Rubber's side effects."

"I'll see whether I can refine a medicine that enhances Whale Rubber's body-strengthening effects while eliminating its side effects."

"A large part of why I became your disciple and began studying Pharmacology and Toxicology was because of this."

But as he spoke, Ye Yu seemed to recall something and sighed with emotion.

"However, there are many medicinal herbs that contain life force, such as ginseng and lingzhi."

"But cold-natured medicinal herbs are extremely rare on the market."

"I'm afraid refining this body-strengthening medicine will be rather difficult."

After saying that, Ye Yu sighed softly and glanced at Dugu Bo from the corner of his eye, thinking to himself.

I've already revealed the secret that Whale Rubber can strengthen the body, and I've spelled things out this clearly.

I wonder whether this Old Poison Master will catch on.

In the end, Dugu Bo did catch on.

Since they were currently in Sunset Forest...

And Ye Yu had just rendered a great service by helping Dugu Yan successfully obtain an External Soul Bone...

After thinking it over, Dugu Bo finally spoke.

"As for cold-natured medicinal herbs, I have quite a few in my herb garden."

"You helped our Dugu Family find a solution to the Jade Phosphorous Poison, and you also helped Yanyan obtain an External Soul Bone."

"That counts as a great favor to our Dugu Family!"

"Back in Heaven Dou Imperial City, many people think all sorts of bad things about me—saying I'm arrogant, eccentric, and fickle."

"But there is one thing everyone acknowledges about me: I always repay favors!"

At this point, Dugu Bo stood with his hands clasped behind his back, his sinister face filled with pride.

"Since you intend to study this medicine, I'll take you to my herb garden. Pick whatever medicinal herbs you want yourself."

"But if you truly manage to develop such a medicine..."

"I hope you'll give some to Yanyan as well."

Seeing that Dugu Bo had finally caught on, Ye Yu was thrilled and excited, and immediately replied.

"Rest assured, Teacher! I've been an orphan since childhood and have no family."

"In my heart, Yanyan is the most important person in this world!"

"Once I develop this body-strengthening medicine, I'll definitely give some to Yanyan!"

After that, led by Dugu Bo...

Ye Yu and Dugu Yan headed together to the Ice and Fire Yin Yang Well.

After passing through the dense forest along the long journey...

And then crossing the poison formation Dugu Bo had set up...

An incomparably towering mountain peak appeared before Ye Yu, its summit spewing thick white mist that lingered around it for a long time without dispersing.

Dugu Bo tucked Ye Yu and Dugu Yan under his arms, one on each side, then leaped into the air.

They soon arrived at a small valley halfway up the mountain.

The valley was filled with dense white mist.

Nothing could be seen clearly.

Only deeper inside could they vaguely make out icy-blue and fiery-red radiance.

"Follow me!"

Under Dugu Bo's lead, Ye Yu and Dugu Yan walked into the valley.

After passing through the thick white mist...

Their view suddenly opened up.

Before them lay a strange pool that seemed crafted by the gods.

The pool was circular and more than ten meters in diameter.

One half was entirely icy blue, emitting bone-piercing cold, while the other was fiery red, radiating scorching heat.

Like an ice-and-fire taiji diagram, the two halves embraced one another, their boundary between them distinct.

The dense white mist filling the valley was formed when the frigid cold and blazing heat emitted by the two pools of completely opposing natures met in the air.

Although Ye Yu knew what the Ice and Fire Yin Yang Well looked like...

And knew it was a miraculous creation of nature beyond compare...

When he truly saw the Ice and Fire Yin Yang Well, he still could not help feeling deeply shaken.

But after glancing at the Ice and Fire Yin Yang Well...

With fiery excitement in his heart, Ye Yu shifted his gaze to its surroundings.

Around the Ice and Fire Yin Yang Well...

Aside from clusters of icy-blue and fiery-red crystals, all kinds of medicinal herbs grew there as well.

Because he had studied Pharmacology and Toxicology under Dugu Bo and knew quite a few medicinal herbs...

Ye Yu recognized Cinnabar Lotus, Cordyceps, ginseng, lingzhi, Fo-ti, and other herbs at a glance.

However, there were also many medicinal herbs growing there that Dugu Bo had never taught him about.

And they were extraordinarily strange and stunning!

For example, there was a massive flower with a three-foot-long stem and no leaves. Its entire blossom was pink, its petals crystal-clear like crystal, and its light-purple pistil seemed inlaid within it like a diamond.

It was about an inch in diameter and emitted a faint fragrance.

It was none other than the Aromatic Silk Beauty!

In addition, there was the Octagonal Mysterious Ice Grass, entirely icy blue, with a large ice-white octagonal flower resembling a snowflake at its top, radiating frigid cold.

There was also the Infernal Delicate Apricot, entirely fiery red, with long slender stems and leaves, its flower shaped like a cabbage and giving off blazing heat.

And there was a Cockscomb Phoenix Sunflower, fiery red all over and soft-looking, its flower as gorgeous as a rooster's comb, its leaf veins golden, likewise radiating heat, among others.

Yet what drew Ye Yu's attention the most...

Was a cluster of bamboo that was pitch-black throughout. Its stalks were as translucent as ink jade, and its leaves were likewise made of ink jade, with only the joints and leaf veins colored gold.

"This is... Ink Jade Divine Bamboo!"

Upon discovering the Ink Jade Divine Bamboo, Ye Yu was immensely excited.

Because among the immortal herbs growing around the Ice and Fire Yin Yang Well in the Douluo series...

If one had to name the immortal herb with the greatest strengthening effect and compatibility for the Blue Silver Grass Martial Soul...

It would undoubtedly be the Ink Jade Divine Bamboo!

In the Douluo series...

The Ink Jade Divine Bamboo was an immortal herb that only appeared during the era of Douluo Three: Legend of the Dragon King.

Ye Yu had thought it might not have grown around the Ice and Fire Yin Yang Well yet!

He had not expected it to already be here!

"Teacher, you actually have immortal herbs here!"

After looking over the medicinal herbs surrounding the Ice and Fire Yin Yang Well, Ye Yu could not contain his excitement as he spoke to Dugu Bo.

"Immortal herbs? What immortal herbs?"

Dugu Bo froze for a moment.

"Before, I read an ancient orphaned copy of a book that recorded many medicinal herbs found across the continent."

"The most powerful medicinal herbs among them were called immortal herbs."

"Their effects could be said to surpass even the Ten Thousand Year Ginseng King!"

"And not only can these immortal herbs greatly increase a Soul Master's cultivation..."

"Some can even allow specific types of Martial Souls to evolve!"

"I discovered that quite a few immortal herbs are growing in your herb garden, Teacher!"

Suppressing his fiery excitement, Ye Yu said.

"What! These immortal herbs can even make Martial Souls evolve?"

Upon learning that the immortal herbs had such astonishing effects and could even allow Martial Souls to evolve...

Dugu Bo's eyes widened in shock. Filled with excitement and anticipation, he immediately asked.

"Kid, hurry up and see whether there are any immortal herbs here that can make our Jade Phosphorous Serpent Martial Soul evolve!"
