The Ice and Fire Yin Yang Well was a divine treasure bestowed by the heavens. Every medicinal plant nurtured here grew at several times the speed of those outside, and their quality was unmatched—this place was truly nature's gift.
In later generations, it was revered as a sacred ground and tightly controlled by the Tang Sect, founded by Tang San, becoming the main cultivation base for their medicinal herbs.
But now, the Ice and Fire Yin Yang Well remained undeveloped. Only a small area of its fertile land had been cultivated by Poison Douluo, and its true value was far from fully realized.
Pointing to the mist-shrouded valley below, Poison Douluo said,
"My herb garden is down there. Come with me."
With that, he leaped straight down with Dugu Yan in tow.
Sword Douluo glanced at Chen Feng, who gave a small nod, and then he followed, bringing Ning Fengzhi and Chen Feng with him.
As they landed, a rich herbal fragrance instantly filled the air. The essence of nature was on full display—exotic flowers and plants dazzled the eyes, and the air was so fresh it felt like standing in the world after a cleansing rain.
Even the well-traveled Ning Fengzhi couldn't help but exclaim,
"What an extraordinary place!"
"Of course it is!" Poison Douluo replied proudly.
"It took me more than ten years of searching to find this spot."
"Let's skip the pleasantries," he continued.
"Chen Feng, didn't you say you could cure my poison? I'll give you full access to this valley for now. You may use any herbs you need. But if you can't even suppress my poison in the slightest, then even with Ning Fengzhi and Sword Douluo here, don't even think about leaving with a single blade of grass."
He cast a glance at the two Titled Douluos beside him and added,
"I trust neither of you will stoop to robbing me, right?"
Ning Fengzhi chuckled,
"Of course not. What do you take the Seven Treasure Glazed Tile Sect for? While we may not be the closest of friends, we're certainly not thieves."
"Good. I trust your word, Sect Master Ning," Dugu Bo nodded.
Chen Feng took a deep breath and said,
"Then I shall begin."
Dugu Bo gave him a nod,
"Go ahead. If you can cure even a trace of the poison in me or Yan Yan, forget a few herbs—you can have this entire valley."
To him, this valley existed solely to suppress the poison in his and his granddaughter's bodies. Beyond that, he neither knew nor cared about its other uses.
Under everyone's gaze, Chen Feng slowly approached the edge of the Ice and Fire Yin Yang Well.
The closer he got, the more likely he was to find the celestial herbs he sought. He had to locate the legendary plant—only it could suppress the Emerald Phosphor Serpent Emperor's poison quickly and effectively enough to earn Poison Douluo's trust.
All around him, flowers bloomed in vibrant colors. The overwhelming fragrance in the air was both alluring and dangerous. Chen Feng used his soul power to seal his nose and mouth as he walked carefully.
Different herbs might emit conflicting toxins—if you inhaled the pollen from just one, it might be harmless, but if two incompatible types were inhaled together, they could combine into a deadly poison.
As he walked, Chen Feng mentally recalled the herb illustrations from his past life, searching intently.
Soon, a large, pale pink flower caught his eye.
"Fragrant Silk Immortal!" he gasped with delight, confirming its identity.
The pale pink blossom had no leaves. Its stalk was nearly a meter tall, and its petals glistened like translucent crystal. At its center were clusters of deep violet filaments, like tiny amethysts embedded in the flower.
"Fragrant Silk Immortal—renowned for its ability to neutralize all poisons. Known as the nemesis of a hundred toxins!"
Carefully, Chen Feng retrieved a pair of protective gloves from his Twenty-Four Moonlit Bridges storage and gently plucked a single petal.
"Senior Dugu," Chen Feng said, returning to the group with the glowing petal cradled in his soul power,
"Didn't you want to suppress your poison? Please take this."
Poison Douluo blinked, staring skeptically.
"You're not trying to fool me with some random flower, are you? I don't recognize this at all."
Chen Feng smiled knowingly. Of course, Dugu Bo wouldn't recognize it. This flower's true value hadn't been discovered until Tang San later experimented with it. It was only through his Tang Sect disciple Yang Wudi that its full potential was unlocked.
The Fragrant Silk Immortal couldn't cure poison outright, but its natural detoxifying aura could harmonize with nearly any venom, making it the most effective foundational herb for suppressing toxins.
"You want to know if I'm lying?" Chen Feng asked.
"Just try it. That'll be your answer."
Dugu Bo eyed him suspiciously, then asked,
"How do I take it?"
"Just eat it," Chen Feng replied simply.
Without further hesitation, Dugu Bo tossed the petal into his mouth.
The translucent petal dissolved the moment it touched his tongue, and a wave of strange warmth spread from his throat to his lower abdomen.
In an instant, his entire body felt lighter. From every pore, threads of greenish-black impurities began to seep out.
As he circulated his soul power, those impurities vaporized into wisps of dark green fog, rising from his body in an eerie spectacle.
"It works!" Dugu Bo exclaimed, his eyes lighting up.
"While it hasn't eliminated the poison," he admitted,
"It weakened it substantially, and it even activated the anti-toxin pills I recently took! Kid, quick, go harvest that whole plant for me!"
"No need to rush, Senior."
Chen Feng shook his head.
"This flower is the Fragrant Silk Immortal. It cannot cure you, only suppress. Even one petal is enough to balance the toxins within you. Taking more won't help. To truly detoxify your body, other methods are still required."
"Then what are you waiting for? If you can cure the Emerald Phosphor Serpent's poison, I'll agree to whatever conditions you ask!"
Chen Feng smiled.
"Then, Senior… does this mean you believe me now?"
"I do. I do. Chen Feng, I didn't expect someone so young to be so knowledgeable in toxicology. I underestimated you." Dugu Bo's expression softened considerably.
Chen Feng thought to himself,
Toxicology, my ass. I just memorized this stuff from the books. If you came from five hundred years in the future, too, you'd know even more than I do.
Of course, he couldn't say that aloud.
Chen Feng raised a single finger.
"Good. Now that you trust me, I'd like to make one condition."
"Go ahead—speak your terms!" Dugu Bo said boldly with a wave of his hand.
Chen Feng smiled inwardly. So the venomous old man had his charming side after all. The world said Dugu Bo was cold and ruthless like a snake—but right now, he seemed almost… endearing.
"Then I'll say it," Chen Feng said.
"My condition is this: I must be allowed to harvest the celestial herbs I need before I begin preparing the antidote."
This, after all, was his real objective. Helping Dugu Bo was just a necessary step along the way.
