Ice and Fire Yin Yang Well

According to the information in his memories, the Ice and Fire Yin Yang Well was located in a valley within Sunset Forest. The valley's outskirts were blanketed in poisonous mist and miasma, a defensive measure Dugu Bo had arranged using the area's natural conditions.

Mu Yuan headed straight there and soon found the valley.

As he stepped into the poisonous fog, vast amounts of toxic mist seeped in from every direction and surged toward Mu Yuan.

This was the deadly poison Dugu Bo had specifically set up. Even ten-thousand-year soul beasts would not dare touch it lightly.

Yet when the toxins landed on Mu Yuan, they could barely affect him. Instead, his martial soul swiftly absorbed them and converted them into stored Soul Power.

At its core, poison was also a form of energy.

Mu Yuan's martial soul possessed an extremely powerful devouring trait, constantly absorbing energy from the outside world. Even toxins could be absorbed and converted into Soul Power, so long as they were not overwhelmingly stronger than him.

After passing through the poisonous fog, an inverted V-shaped valley appeared before Mu Yuan.

Thick heat rose from within the valley. The heat was intense enough that anyone unfamiliar with the place might mistake it for a hot spring below.

Of course, in a sense, the Ice and Fire Yin Yang Well could indeed be considered a hot spring.

Mu Yuan leaped down into the valley, and the sight before him was utterly refreshing.

An enormous spring came into view. The oval pool was clearly divided into two halves, one milky white and the other crimson red.

This was the legendary Ice and Fire Yin Yang Well. It was said to have formed from the corpses of the Water and Fire Dragon Kings, two of the original nine Dragon Kings of Douluo Continent.

He wondered whether digging downward from the location of the Ice and Fire Yin Yang Well would uncover the remains of those two Dragon Kings.

All sorts of strange plants grew around the Ice and Fire Yin Yang Well. Some were blue and looked incomparably cold, while others were red and seemed blazing hot. Others radiated a faint glow over their entire bodies, appearing extraordinarily noble at a single glance.

Among these plants, Mu Yuan recognized only a few Immortal Herbs with distinctive characteristics that had been introduced in the original work, such as the Octagonal Mysterious Ice Grass, Infernal Delicate Apricot, Aromatic Silk Beauty, Singular Velvet Sky Chrysanthemum, Lovesick Heartbreak Red, and so on.

As for the other plants, there were surely many precious medicinal herbs and Immortal Herbs among them, but Mu Yuan could not identify them all.

Dugu Bo did not seem to be here at the moment. Mu Yuan had trespassed into his herb garden for so long, yet he had not shown himself.

Mu Yuan simply waited where he was.

While waiting, Mu Yuan sat cross-legged and prepared to cultivate as well.

Just then, the Divine Tree Martial Soul within Mu Yuan suddenly stirred. An incomparably intense sense of yearning arose, pointing directly toward the Ice and Fire Yin Yang Well not far away.

"What is this?" Mu Yuan followed the guidance of his Divine Tree Martial Soul and approached the Ice and Fire Yin Yang Well.

The closer Mu Yuan came, the stronger the Divine Tree Martial Soul's longing became.

When Mu Yuan stood before the Ice and Fire Yin Yang Well, he could sense that the Divine Tree Martial Soul desperately wanted to devour the energy in the spring water. Once it succeeded, he would undoubtedly gain enormous benefits.

But Mu Yuan ultimately did not make a move.

He wanted to obtain the Ice and Fire Yin Yang Well from Dugu Bo through an open and honest exchange, not by stealing it.

Mu Yuan continued waiting.

After some time, the sound of something tearing through the air rang out.

A dark green figure swiftly descended from the sky, with someone Mu Yuan recognized in his hand.

Tang San?

Mu Yuan was greatly surprised. Why was Tang San here?

Moreover, he seemed to be in terrible condition, dangling unconscious in Dugu Bo's hand like a dead dog.

Dugu Bo said in a deep voice, "Kid, you managed to sneak in here while I was away. You've got some skill!"

Seeing Mu Yuan looking at Tang San in his hand, Dugu Bo asked, "What? You know him?"

Mu Yuan nodded lightly.

"He's my classmate."

Dugu Bo raised a brow and said in surprise, "Is your teacher also that Egg-Boiling Master, Yu Xiaogang?"

A flood of question marks immediately arose in Mu Yuan's mind.

Egg-Boiling Master?

What kind of title was that?

What Mu Yuan did not know was that Xue Beng had given Grandmaster this nickname.

Since Mu Yuan had not shown himself for quite some time after joining Heaven Dou Royal Academy, Xue Beng no longer had anyone to fear and began stirring up trouble outside again, playing the role of a spoiled young noble.

It so happened that Grandmaster had clashed with the teachers of Heaven Dou Royal Academy over certain teaching matters.

Grandmaster had Tang San practice the technique of Boiling Eggs Through the Urn to train his control over Soul Power.

Yet Tang San practiced for a long time without achieving any results.

By coincidence, several Heaven Dou Royal Academy teachers passed by that day. The moment they saw it, they laughed themselves silly. This training method was only suitable for soul masters with flame-related martial souls. Tang San's martial soul was Blue Silver Grass, so how could he possibly use Soul Power to boil eggs inside a water urn?

Before long, the matter spread throughout the academy.

After hearing about it, Xue Beng sent people to investigate Grandmaster.

When he learned that Grandmaster was merely a useless level twenty-nine Soul Grandmaster who nonetheless often called himself some sort of martial soul master, Xue Beng gave him the nickname "Egg-Boiling Master," making the entire academy laugh at him.

At first, Tang San did not want to interfere, because he was also dissatisfied with Grandmaster.

He had believed that so-called technique and foolishly practiced it for a long time, wasting a great deal of time and energy, only for it all to come to nothing.

But after Grandmaster became the laughingstock of the entire academy, Tang San was implicated as well.

The Heaven Dou Royal Academy students labeled him the disciple of the Egg-Boiling Master, which made Tang San feel deeply humiliated.

So Tang San found Xue Beng and gave him a vicious beating, venting the anger in his heart.

Naturally, Xue Beng was unwilling to let the matter rest after being beaten.

He could endure it when Mu Yuan was around, but with Mu Yuan absent, continuing to endure would be ridiculous.

Xue Beng immediately sought out his uncle, Prince Xue Xing. Prince Xue Xing and Dugu Bo were good friends, and Dugu Bo happened to be visiting Prince Xue Xing's residence at the time.

After hearing that Xue Beng had been bullied, Prince Xue Xing immediately decided to stand up for him.

Dugu Bo also wanted to visit Dugu Yan at Heaven Dou Royal Academy, so he accompanied Prince Xue Xing there.

After arriving at Heaven Dou Royal Academy, Dugu Bo heard from Dugu Yan that Tang San had once used alcohol to neutralize her poison. This piqued Dugu Bo's interest in Tang San.

Thus, Dugu Bo knocked Tang San unconscious and captured him.

Having just returned, Dugu Bo sensed that someone had intruded into his herb garden. He therefore rushed over immediately, without even having time to put Tang San down.

That was how the current situation came about.

Mu Yuan did not know these details, but he did not need to.

He had come here only to exchange for the Ice and Fire Yin Yang Well with Dugu Bo.

Dugu Bo cultivated Poison Cultivation, but he found it difficult to suppress the toxins steadily growing inside his body. Thus, he relied on the power of the Ice and Fire Yin Yang Well to help suppress the poison within him.

At the same time, Dugu Bo used the Ice and Fire Yin Yang Well to cultivate many medicinal herbs, hoping to develop a method through those herbs to resolve his physical problems.

This was also why Dugu Bo had become interested in Tang San.

And Mu Yuan had brought a method that could directly solve this problem.
