The Ice and Fire Yin Yang Well was located deep within the Sunset Forest. From Heaven Dou City, even with Sword Douluo personally leading the way, the group still needed two full days to reach it.
Although the Sunset Forest wasn't as vast or dangerous as the Star Dou Great Forest, it still housed many powerful soul beasts. Without the protection of a Titled Douluo, any ordinary soul master attempting to enter the core region would be risking their life.
Following Chen Feng's guidance, the group gradually approached a hidden valley.
Suddenly, Sword Douluo, who was leading the way, raised his head and let out a long, resonant howl.
Seconds later, another howl echoed from deep within the valley, responding in kind.
Recognizing the voice, Ning Fengzhi smiled and said, "It's Poison Douluo—he is here. Chen Feng, your predictions are uncanny."
As if to prove Ning Fengzhi's words correct, a gust of wind suddenly swept past them, and a sharp, swift figure shot across the ground like lightning.
"Ning Fengzhi. Sword-wielding Chen Xin. Long time no see. What brings you here with my granddaughter?"
The raspy voice of Dugu Bo rang out.
Clad in a gray robe, Poison Douluo had a lean, javelin-like frame. His hair and beard were all a deep emerald green, and his eyes gleamed like polished jade stones.
However, his expression was far from pleasant. Seeing Dugu Yan with these two powerful figures and being brought straight to his "secret base," it felt suspiciously like she'd been coerced.
"Are they here to hold me accountable? Did Yan Yan cause some great trouble with the Seven Treasure Glazed Tile Sect? And how the hell did they find this place?"
Dugu Bo's eyes shifted with doubt, unable to make sense of it all.
Ning Fengzhi smiled politely. "It's been a long time, Dugu Bo."
Sword Douluo, on the other hand, was much more blunt.
"Old poison geezer, we came to see if you'd died already—wanted to claim your corpse. Didn't expect you to still be kicking."
Dugu Bo snorted coldly.
"If you're still alive, how could I be dead? Enough nonsense. Speak your business. I don't have time to chat. Yan Yan, come here to Grandpa."
Dugu Yan quickly walked to his side without hesitation.
Seeing that she wasn't being restrained, Dugu Bo finally relaxed. At the very least, this meant she hadn't been kidnapped or used as leverage.
Ning Fengzhi cupped his hands in greeting.
"Dugu Bo, you and I go way back. Let me introduce someone. This is Chen Feng, the new Honorary Elder of our Seven Treasure Glazed Tile Sect."
"What?" Dugu Bo raised a brow and chuckled dryly.
"This brat? He looks even younger than my granddaughter, and you made him an elder?"
His voice rasped with disbelief, bordering on mocking.
Ning Fengzhi simply looked at Chen Feng and nodded.
Chen Feng stepped forward, cupped his fists respectfully, and said,
"Senior Poison Douluo, I'll be frank—we came here because I have a request. Sect Master Ning and Sword Grandpa merely accompanied me."
"Oh? You're looking for me? What for?"
"Medical treatment."
"Hah! I'm not a doctor. If you're sick, I probably can't help you," Dugu Bo shook his head dismissively.
Chen Feng calmly pointed toward both Dugu Bo and Dugu Yan.
"Senior, you misunderstand. I'm not the one who's sick. You and your granddaughter are. I came to treat you."
"Nonsense!" Dugu Bo immediately snapped.
But Chen Feng didn't get angry—instead, he smiled calmly.
"Please, don't take offense. I meant no insult. I came because of the poison from the Emerald Phosphor Serpent Emperor."
At those words, Dugu Bo's eyelid visibly twitched. Chen Feng's words had hit a nerve.
"Sickness isn't just something you can see with the naked eye," Chen Feng continued.
"Senior, while your cultivation has reached the level of Titled Douluo, the poison of your Martial Soul has invaded every corner of your body."
"To put it bluntly… you're already at the point of no return. Even if I wanted to cure you, the odds are slim. But… shouldn't you at least consider your descendants?"
He glanced at Dugu Yan meaningfully as he spoke.
Dugu Bo looked at his granddaughter, then back at Chen Feng, his eyes filled with doubt and contemplation.
Chen Feng wasn't impatient. He knew Dugu Bo must be wrestling internally. After all, if Dugu Bo could truly cure this affliction, he would've done it long ago—his son wouldn't have died, and things wouldn't have dragged on this far.
"Kid, why should I believe you?" Dugu Bo finally asked after a brief silence.
Chen Feng chuckled.
"If you're willing to believe me, I'll prepare some medicine. Try it—you'll know whether it works or not."
"If not, then no amount of explanation will convince you. But let me say this: don't come looking for me once the damage is irreversible—by then, even I won't be able to save you."
With that, Chen Feng clasped his hands behind his back and turned away, waiting for Dugu Bo's decision.
After a long moment, Dugu Bo said:
"Alright, kid. Tell me your conditions. No one helps others out of pure kindness—you must want something."
He was prepared for outrageous demands.
But to his surprise, Chen Feng merely smiled and said,
"Of course I want something. I would like permission to pick a few medicinal herbs from your garden."
"What? You do realize how hard my poison is to treat, right? And you're asking for a few plants?" Dugu Bo stared at him like he'd lost his mind.
"If my medicinal field had miracle herbs, don't you think I'd have used them already?"
But Chen Feng replied confidently,
"That's exactly my request. I won't lie—your herb garden contains several celestial-grade herbs. Perhaps you don't recognize them, or don't know their true effects. All I need is a few specific ones."
He spoke openly, without a hint of deception.
He had no intention of pulling a Tang San, who had looted the entire herb garden and still acted like Dugu Bo owed him a favor.
Dugu Bo frowned.
"Kid, how about you show me the so-called 'celestial herbs' first? To be honest, I know every plant in that field. I've never heard of celestial herbs. Enlighten me—and if I'm impressed, I'll believe you."
Chen Feng nodded.
"Deal."
The group followed Dugu Bo toward the valley.
The area was a deep, inverted-cone-shaped basin, surrounded by sheer cliffs. A pungent sulfuric odor wafted from below, and thick mist drifted upward, giving the place an otherworldly, yet dangerous, atmosphere. The ground beneath their feet was obscured, heightening the sense of danger.
Chen Feng immediately activated his Sword Dao Heavenly Eye. Though he lacked the soul bone from his previous life, even the basic version was enough to pierce the fog.
Below, a pool of water came into view—a breathtaking sight.
At the center of the basin lay an oval-shaped pond, its waters split into two distinct colors: one half a vivid scarlet red, the other a milky white. Miraculously, despite sharing the same body of water, the two colors remained perfectly separate, never mixing, as if held apart by some invisible force.
It was the legendary—
Ice and Fire Yin Yang Well!
