" The Ice and Fire Yin Yang Well?" Dugu Bo turned to look at the two-colored spring. "This spring is called the Ice and Fire Yin Yang Well?"
Shen Feng confirmed, "That's right. Ancient texts say that one spring gives rise to two, and the two forces oppose each other. Hence, it is called the Ice and Fire Yin Yang Well."
"This place is paradise for plants and hell for animals."
"Its spring water contains the power of extreme ice and fire elements, making it extremely dangerous."
"Not only that, the Ice and Fire Yin Yang Well affects the area around it, filling the air with large amounts of ice- and fire-type natural energy."
"When humans or animals come near the Ice and Fire Yin Yang Well, their bodies are invaded and assaulted by these two extreme types of natural energy in a short time. If they can't leave in time, they're sure to explode and die."
"But these two special types of natural energy are the best catalysts for plant growth. Any plant that can take root and survive near the Ice and Fire Yin Yang Well can grow ten times faster, eventually becoming an extremely rare and precious medicinal herb."
"In other words, a ginseng plant that grows here for ten years will have the medicinal effects of a hundred-year-old ginseng."
"It's precisely because these two extreme types of natural energy protect this place that the plants here can steadily accumulate medicinal properties and quickly grow into rare herbs of great age."
"This is also the place with the most Immortal Grade Herbs, and each one has the power to seize the workings of nature and turn the ordinary into the miraculous."
"Old sir, with this place at your disposal, you and Sister Yanyan can put all your worries about the hidden dangers in your bodies behind you."
Dugu Bo said excitedly, "Xiao Feng, is that really true?"
Shen Feng nodded slightly. "Of course."
As he spoke, Shen Feng pointed to the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot on opposite sides of the Ice and Fire Yin Yang Well.
"The Octagonal Mysterious Ice Grass and Infernal Delicate Apricot are both Immortal Grade Herbs. Taken separately, they're highly toxic. Even a Titled Douluo couldn't withstand their medicinal properties."
"But their properties are diametrically opposed. If you take them together, they'll counteract each other, balancing each other out."
"The way to use them is to take the two Immortal Herbs together, then jump into the Ice and Fire Yin Yang Well within ten breaths to undergo Ice and Fire Body Tempering. That'll forge a body immune to water and fire, and impervious to a hundred poisons."
"If you take them, all your hidden dangers will be eliminated. Then we can use your blood to make Antitoxin Serum and cure Sister Yanyan's hidden danger as well."
Before Dugu Bo could respond, Shen Feng pointed again, this time at a huge chrysanthemum in the flower bed.
"The Singular Velvet Sky Chrysanthemum is a neutral Immortal Grade Herb. Eating it sends energy to all four limbs and circulates blood through all eight meridians. It can forge an Indestructible Vajra Body."
"This is the Reinforcement Method I mentioned to you. A stronger, healthier body naturally has a greater ability to expel toxins, enough to fight the poison in your body."
As he spoke, Shen Feng pointed to a beautiful orchid.
"The Eight-Petal Immortal Orchid has mild, mellow medicinal properties and is easy to absorb. It can strengthen the body's foundations and eliminate impurities."
"If you take it, it might also eliminate your hidden dangers. For Sister Yanyan, it would remove hers completely."
Suddenly, as if he'd spotted something, Shen Feng rushed straight through Dugu Bo's Soul Power barrier and stopped in front of a vine-like plant glowing with precious light.
"It's an Earth Dragon Golden Melon!"
"Legend has it that this plant grows after being bathed in dragon's blood. Eating it can evolve dragon-type Martial Souls and grant them control over earth."
"If you take it, not only will your body grow stronger, but your Martial Soul may well evolve into a true dragon-type Martial Soul."
"Of all the Immortal Grade Herbs here, the Earth Dragon Golden Melon is definitely the best fit for you."
"There's also a Red Blood Dragon Vine here? Too bad it's too young to qualify as an Immortal Grade Herb. But it could still be used as the main ingredient in a medicine for Sister Yanyan, and help eliminate the hidden danger in her body."
"And this is Dragon Saliva Grass? It's a little young too, but it's highly nourishing for dragon-type Martial Souls."
Watching Shen Feng flit through the medicinal plants like a happy butterfly, searching while chattering away about their uses, Dugu Bo felt like a complete fool—a fool who'd entered a mountain of treasures without realizing it, begging for scraps while holding a golden bowl.
In just this short time, Shen Feng had found more than ten precious herbs that could completely cure Dugu Yan and even help with his own hidden dangers.
Meanwhile, he'd spent years suffering and agonizing over the hidden dangers in his body.
Even Dugu Yan's expression as she looked at Dugu Bo had changed. It held a third pity, a third confusion, a third bewilderment, and a final third distrust.
Unable to bear Dugu Yan's complicated gaze, Dugu Bo shook his head with a wry smile and beckoned Shen Feng over.
"Xiao Feng, take a break. Those herbs have been growing there for who knows how long. They're not going anywhere."
"Come over here so we can discuss it and choose the best approach to eliminate the hidden danger in Yanyan's body first."
Hearing Dugu Bo call him, Shen Feng reluctantly stopped searching. He wiped the drool from the corner of his mouth and said, "All right, coming."
Perhaps because the Ice and Fire Yin Yang Well on the Douluo Continent had formed from the remains of the Fire Dragon King and Water Dragon King after their deaths, there were an unusually large number of dragon-related medicinal plants here.
After discovering the Earth Dragon Golden Melon, Shen Feng had found plenty of other precious dragon-related herbs nearby.
None of them qualified as Immortal Grade Herbs, but when combined with other herbs to fully activate their medicinal properties, they could still be quite effective in treating Dugu Bo, let alone eliminating the hidden danger in Dugu Yan's body.
After thinking it over, Shen Feng decided to take a conservative approach to treating Dugu Yan.
"Old sir, Sister Yanyan, there are many herbs here that can eliminate the hidden dangers in your bodies. But different combinations produce completely different effects."
"Some may only eliminate the hidden danger, while others could strengthen the body's foundations and improve your aptitude at the same time. They might even unlock your potential directly and increase your cultivation."
"When it comes to treating Sister Yanyan, I think we should play it safe. After all, these herbs are extremely rare. If anything goes wrong, even the gods won't be able to save us."
Dugu Bo thought it over and nodded seriously. "You're right. Different medicinal properties produce different effects when combined. Mix them carelessly, and even a tonic can kill someone."
"I've studied these herbs for many years, but I've only learned a little about their properties. Since you recognize them, Xiao Feng, you must know the right formulas for using them, too."
Shen Feng nodded. "I only know a few formulas, but they'll be more than enough to treat the hidden dangers in your bodies."
As he spoke, Shen Feng smiled mysteriously and pointed to a large pink flower among the plants.
The huge flower had no leaves. Its stem was three feet long, and the blossom was enormous, a full foot across. Each petal looked as clear and lustrous as crystal. Its stamens were pale purple, like purple diamonds set in the center of a pink petal platter.
A breeze passed, and the flower swayed gently amid the mist. Fine pollen drifted down, sparkling in the air with dazzling pinpricks of light. It was breathtakingly beautiful.
"This flower is called Aromatic Silk Beauty. It's the bane of all poisons, capable of neutralizing any toxin. It can't detoxify on its own, but it can counteract poison."
Dugu Bo nodded slightly. "I know. As long as you stand within the range of its pollen, you won't be poisoned."
"But unfortunately, it has no effect on creatures that are already poisoned. Otherwise, I wouldn't have left it here all this time."
Dugu Bo had discovered the Ice and Fire Yin Yang Well who knew how many years ago. He might not have known the precise properties of these Immortal Grade Herbs, but he understood some of their more obvious effects.
Shen Feng nodded with a smile. "You're right, old sir. That's why it has to be used alongside another Immortal Herb."
Dugu Bo looked where Shen Feng pointed, and a snow-white Immortal Herb came into view.
The plant was crystal-clear and white as snow, with long, curved leaves that looked as if water might drip from them at any moment. It looked just like a swan's neck.
The moment Dugu Bo saw it, his pupils contracted. His expression turned grave, and even hinted at fear.
"Xiao Feng, are you joking with me? Do you know what that thing is?"
Dugu Yan looked at Dugu Bo curiously. "Grandpa, what's wrong with that herb? Why are you so afraid of it?"
Dugu Bo shuddered involuntarily. "Yanyan, listen to your grandpa. Never go near that poisonous plant."
"About ten years ago, when I first discovered this place, I faced two brushes with death."
"One was when I came into contact with that two-colored spring. The other was when I touched that poisonous plant shaped like a swan."
"If I hadn't already been a Titled Douluo, and if I hadn't only touched them tentatively, I might have been buried here."
Even now, remembering what had happened ten years earlier still made Dugu Bo uneasy.
Dugu Yan was shocked. Her beautiful eyes widened as she stared at Dugu Bo in disbelief.
"W-was it really that bad?"
"It was," Shen Feng replied. "This plant is called Snowy Swan Kiss."
"But the old sir got one thing wrong. It isn't a poisonous plant, and it doesn't contain a trace of poison."
"It has only one property: it can amplify any toxin a thousandfold."
"The reason you found it so terrifying, old sir, is that you're a walking poison container. If its pollen or sap touched you, the toxins in your body would naturally multiply out of control."
"Luckily, you were cautious back then and only touched it to test it. Otherwise, all we might have found of you would've been your bones."
"I seriously suspect that the hidden dangers in your body became so severe because you once came into contact with Snowy Swan Kiss."
Dugu Bo furrowed his brow and pondered for a moment before nodding slightly. "You make a good point."
"But Yanyan also has poison in her body. Having her take this herb doesn't sound like a very safe treatment."
Shen Feng gave a cheeky grin. "Actually, treating Sister Yanyan will take three steps."
"First, we eliminate the hidden danger in your body, then extract Antitoxin Serum from your blood to cure Sister Yanyan."
"Second, we have Sister Yanyan take Aromatic Silk Beauty and see if she can gain the ability to resist all poisons."
"Third, once we've confirmed that Sister Yanyan is immune to all poisons, we try giving her Snowy Swan Kiss to see if she can gain the ability to multiply toxins a thousandfold."
"If she can complete all three steps, tsk, I can't even imagine how terrifying Sister Yanyan will become."
Dugu Yan stared at Shen Feng in astonishment. "Could I surpass Grandpa and become the greatest poison-type Soul Master in the world?"
"Little brother, I have to say, this plan is brilliant."
"Grandpa, let's do it. I'm willing to try."
A Soul Master's growth was always accompanied by countless risks. Soul Hunting was dangerous, absorbing Soul Rings was dangerous, and fighting others for resources was dangerous, too.
So for the sake of power, Dugu Yan didn't mind taking a few minor risks.
Besides, Shen Feng's plan had three steps. If anything seemed wrong, they could simply stop at any point.
Dugu Bo furrowed his brow, pondered for a long time, then nodded. "All right, but we must make sure there's no danger."
Shen Feng smiled. "Of course. Sister Yanyan is my sworn big sister. There's no way I'd harm her, right?"
"Now, old sir, please take the Earth Dragon Golden Melon and eliminate the hidden danger in your body."
Dugu Bo paused, then turned to Shen Feng. "What about you, brat? Haven't you picked an Immortal Grade Herb for yourself?"
Shen Feng smiled mysteriously and pointed at the Ice and Fire Yin Yang Well. "I have, of course."
Dugu Bo's pupils contracted sharply. "Think carefully, brat. Those are the most dangerous of all poisonous plants, and the way to use them is the most perilous."
Shen Feng's expression was calm. "As the saying goes, the bigger the waves, the more expensive the fish. Risk and opportunity always go hand in hand."
"I believe they'll be worth the risk."
Dugu Bo clicked his tongue in amazement. "You seem calm, but you're reckless to the bone."
"Since you want to try, you should go first. I'll stay here and keep watch."
Shen Feng turned to Dugu Bo and bowed. "I, Shen Feng, thank you, old sir."
Then Shen Feng walked toward the Ice and Fire Yin Yang Well without looking back, his steps firm and his gaze resolute.
Actually, the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot weren't the best choices for Shen Feng among the herbs in the Ice and Fire Yin Yang Well.
Being immune to water and fire and impervious to a hundred poisons seemed impressive, but for Shen Feng, they were practically useless.
For one thing, Shen Feng was a Power Attack System Soul Master, and the Leiming Blade had a lightning attribute. He already had no fear of water or fire.
The robust body granted by his Body Martial Soul and the Leiming Blade's violent power of lightning also gave him high resistance to poison and sinister energies.
Compared to the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot, two poisonous plants with enormous risks in their use, the Singular Velvet Sky Chrysanthemum was actually the best choice for Shen Feng.
It was low-risk, and its ability to forge an Indestructible Vajra Body, combined with his Body Martial Soul, would make him peerless.
But the Singular Velvet Sky Chrysanthemum was also a good fit for Shen Rui, so Shen Feng had to give it up.
Besides the Singular Velvet Sky Chrysanthemum, Shen Feng had also discovered another Immortal Grade Herb that suited him.
It was a black bamboo shoot less than two feet tall, growing in a corner of a cliff on the very edge of the Ice and Fire Yin Yang Well.
Shen Feng recognized it as an Immortal Grade Herb called Ink Jade Divine Bamboo.
When fused with a Martial Soul, it could greatly enhance that Martial Soul's toughness, sharpness, strength, and other qualities. It was extremely suitable for blade- and sword-type Martial Souls.
But the Ink Jade Divine Bamboo was also a good fit for Ling Na, so Shen Feng had to give it up again.
Still, Shen Feng wasn't the kind of foolish person who would give up his own growth just for his family.
First, the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot could also strengthen the body to a certain extent.
Second, there were hidden benefits at the bottom of the Ice and Fire Yin Yang Well.
