After leaving the Soul Beast materials shop, Lin Feng spent another two days asking different Soul Hunting masters about the location of that mountainous area.
Once he confirmed the route, he prepared jade boxes and harvesting tools, then set off for Sunset Forest.
Half a day later, a cloud of pale green poisonous mist blocked his path.
The surrounding vegetation was lush, yet there was little sound of insects, and traces of corrosion remained on several exposed rocks.
"This should be the place." Lin Feng stopped outside the poisonous mist, picked up a branch from the ground, and slowly extended it inside.
Within moments, a dark green layer appeared on the branch. Seeing this, he hurriedly dropped it and took two steps back.
Lin Feng raised his right hand. Emerald light gathered, and the Soul Devouring Spider Emperor appeared in his palm. He then communicated through his thoughts:
"Help me take a look. Can I get through this poison?"
The green spider raised her forelegs and examined the mist ahead.
"Jade Phosphorous Serpent Poison."
Bibi Dong quickly reached a judgment.
"The poison around the edges isn't particularly concentrated, but the farther in you go, the more potent it should become. With your current strength, charging straight in definitely won't work."
Lin Feng frowned and said:
"Then do I have to wait for Dugu Bo to come out?"
Chrysanthemum Ghost Douluo was most likely nearby, but if he could get his hands on the immortal-grade herbs first, that would naturally be better.
"Who said you have to wait?" Bibi Dong asked in return. "Have you forgotten what your second Soul Skill is?"
"Soul Devouring Spider Web?"
Bibi Dong explained:
"Your webs can carry spider venom, so naturally, they can hold other toxins too. Besides, the Soul Devouring Spider Emperor's control over toxins far surpasses that of ordinary spiders."
Lin Feng asked:
"You mean I should use the webs to absorb the poison?"
Bibi Dong said:
"You can try, but don't think about absorbing this entire cloud of poisonous mist. You only need to clear a path you can walk through. Also, don't draw the poison absorbed by the webs into your body for now."
Hearing this, Lin Feng no longer hesitated. Emerald light surged over his body, and the spider in his palm instantly merged into him. His eyes turned green.
Yellow, purple, purple. Three Soul Rings slowly rose.
His second Soul Ring lit up, and an emerald-green web flew out, landing between two trees ahead.
When the mist touched the silk, it immediately condensed into tiny droplets.
Lin Feng carefully sensed it and discovered that the poison clinging to the silk was slowly seeping inward, though the process was very slow.
"Don't stretch the web too tightly. Try to let your Soul Power flow along the silk," Bibi Dong reminded him through their mental connection.
Following her instructions, Lin Feng adjusted his Soul Power.
The next moment, emerald light flickered faintly across the silk's surface, and the surrounding poisonous mist indeed began gathering toward the web.
The originally emerald-green silk gradually took on an inky hue, while the mist near the web visibly thinned.
"It really works!"
Seeing this, Lin Feng's eyes lit up.
Just as he was about to keep channeling his power, Bibi Dong interrupted him.
"That's enough. This web can't bear any more toxins. Sever your connection to it and leave it where it is, then release another."
Hearing this, Lin Feng immediately stopped.
Looking closely, he saw that several strands saturated with toxins had already begun to soften, and their ends had even started breaking.
Dugu Bo's poison really wasn't so easy to handle.
He released another web, absorbing the poisonous mist ahead bit by bit, and only stepped forward once a small opening appeared.
Throughout the process, he maintained Martial Soul Possession.
With the Soul Devouring Spider Emperor resisting the small amounts of residual poison and Bibi Dong constantly guiding him, Lin Feng finally found a suitable pace.
The webs absorbed poison ahead while he followed behind. Whenever he encountered particularly dense mist, he stopped to lay down several more webs, never venturing in rashly.
His Soul Power drained faster than expected, and sweat gradually beaded on Lin Feng's forehead.
However, as the web absorbed the final layer of poisonous mist, a mountain path leading downward finally appeared ahead.
"I'm through!"
Lin Feng glanced back.
The mist behind him was gathering again, and he could no longer clearly make out those blackened webs.
Without Bibi Dong's guidance, who knows how long I'd have been stuck outside, trying to figure it out myself.
Following the mountain path downward, he soon came upon a valley.
Heat rose within the valley. A strange spring was divided into milky white and vermilion halves. The waters on either side met, yet remained as distinct as the Jing and Wei rivers.
All around the spring, medicinal herbs grew in great abundance.
Lin Feng's gaze swept over the spring's edge. His breathing immediately quickened, and he said in a low voice:
"The Ice and Fire Yin Yang Well! I finally found it!"
He suppressed his excitement and, rather than rushing toward the spring, first looked at the flowers and plants a little farther away.
An enormous chrysanthemum soon caught his attention.
The flower was a magnificent purple, its petals covered in fine fuzz, its golden stamens trembling slightly at the center.
"Singular Velvet Sky Chrysanthemum!" Lin Feng crouched down and examined it carefully. He could no longer hide the smile on his face.
Looking farther to the side, he saw a snow-white orchid growing quietly, its eight petals crystal clear.
"Eight-Petal Immortal Orchid!"
Having recognized two immortal-grade herbs in succession, Lin Feng felt that all the Soul Power he had expended in the poisonous mist had been well worth it.
These were things that Gold Soul Coins alone couldn't buy.
In the original story, Tang San and the others had greatly improved both their strength and talent through immortal-grade herbs. Now that he had reached the Ice and Fire Yin Yang Well ahead of them, there was naturally no reason to leave these fortuitous opportunities for them.
"Don't rush to approach them yet."
Seeing him staring fixedly at the plants, Bibi Dong reminded him, "Some of the medicinal herbs here are deadly poisonous. The closer an immortal-grade herb is to the spring, the less you can afford to touch it carelessly."
"Don't worry. I know my limits." Lin Feng took out the jade boxes he had prepared, then his harvesting tools. He only intended to harvest the immortal-grade herbs he recognized first.
He then carefully parted the branches and leaves around the Singular Velvet Sky Chrysanthemum, checking its features against his memories once more before beginning to harvest it.
Soon, the first immortal-grade herb was placed inside a jade box.
The moment he closed the lid, he couldn't help laughing. Then he turned, walked over to the Eight-Petal Immortal Orchid, and crouched down again.
However, just as he opened the second jade box, an icy voice suddenly thundered from above the valley.
"Boy, what are you doing?!"
Lin Feng's hands paused. He looked up and saw a green figure sweep down the mountain path, landing nearby in the blink of an eye.
The newcomer was tall and thin, with dark green hair and beard. His eyes were fixed on the jade box in Lin Feng's hands, his expression frighteningly grim. It was none other than Dugu Bo!
He had merely gone out for a while, only to return and discover something amiss with his poison formation. Along the way, numerous webs saturated with serpent poison had appeared.
When he reached the herb garden, he actually found a boy crouching there, about to harvest his medicinal herbs!
Dugu Bo looked Lin Feng over a few times and thought, A three-ring Soul Elder? Since when did my poison formation fail to stop even a Soul Elder?
The next second, a wave of icy Soul Power abruptly pressed down.
"Were you the one who left those webs outside? How did you get through this old man's poison formation and make your way here?!"
