Douluo: When the piano sounds, the hidden weapon returns to the factory

Chapter 13 Absorbing Immortal Products
As the lingering sound of the last note slowly faded from Yin-Yang's eyes, Dugu Yan suddenly frowned, her chest heaving violently. "Poof!" A mouthful of emerald green poisonous blood gushed out, glistening eerily in the morning light.

"Yanyan!" Dugu Bo flashed and instantly arrived beside his granddaughter. His green eyes, always sinister, were now filled with worry, and his skinny hands gently patted Duguyan's back.

Dugu Yan wiped the blood from her lips and slowly calmed her breathing. When she opened her eyes again, her emerald pupils were even clearer and brighter than before, and a faint glow of health shone beneath her skin. "Strange," she flexed her wrist, a look of disbelief crossing her face. "Even though I vomited blood, my body feels more relaxed."

Dugu Bo hurriedly grabbed his granddaughter's wrist and, using his soul power to investigate, his eyes lit up. "Thirty percent of the toxin has been expelled!" He turned sharply to Feng Yao, his voice filled with anxiety. "Why isn't the effect as good as yesterday?"

Feng Yao put away his Fuxi, his hair drenched with sweat. He took a deep breath and explained, "Senior, you misunderstood. This Qin Sound Refining Method wasn't designed specifically for detoxification."

"That's..." Dugu Bo frowned.

"Did you feel the resonance between your internal organs and the music just now?" Feng Yao smiled slightly, with a gleam of wisdom in his eyes.

Dugu Bo's expression froze, a sudden thought forming. He flashed before Feng Yao like a ghost, his bony fingers gripping his wrist like a vise. A moment later, the Poison Douluo's eyes lit up with a startling brilliance. "The vitality within him is as thriving as the rising sun. His bone age is only twelve, yet he already possesses a spirit power of level twenty-six."

He released his hand, staring intently at the young man in front of him, his voice trembling slightly with excitement: "Boy, do you know how valuable this secret technique is? Just teach it to me like this, and you won't be afraid..."

Feng Yao met Dugu Bo's gaze, his smile clear as a spring: "I only see a grandfather who wants to save his granddaughter. Besides, the senior has already given me a generous reward."

Dugu Bo's body shuddered, and for the first time, he turned his face away from everyone. In the morning light, the feared Poison Douluo's eyes seemed to gleam. When he turned back, his voice had returned to its usual gruffness: "Boy, I'm a man of my words! Take whatever herbs you like!"

He waved his hand, and his long dark green hair danced wildly in the wind. The strong wind from his sleeves swept up the fallen petals all over the ground. At this moment, no one noticed that Dugu Yan, standing beside him, was looking at Feng Yao with a completely new look, and a complex light flashed in her green eyes.

Feng Yao gently placed the "Fuxi" on his knees, stroked the strings with his fingertips, and said in a gentle voice: "Senior, please don't worry. I will explain in detail the method of tempering the body with the sound of the qin."

His slender fingers gently slid across the strings, producing a clear, melodious sound. "The five notes correspond to the five internal organs: Gong for the spleen, Shang for the lungs, Jiao for the liver, Zhi for the heart, and Yu for the kidneys," Feng Yao narrated, his voice flowing like a clear spring. "Using soul power as a guide and music as a medium, resonance can be achieved with the internal organs."

Dugu Bo nodded thoughtfully, his emerald eyes gleaming with understanding. "So that's how it is. All you need to do is use your soul power to play a specific melody."

"Then can we use a harp?" Dugu Yan suddenly interrupted, her emerald eyes full of curiosity.

Feng Yao turned to look at her with an approving smile in his eyes: "Sister Yan is right. Theoretically, any instrument will do, but" he paused, "you need to be proficient in music theory and have a profound control over your soul power."

Dugu Yan curled her lips when she heard this, obviously disappointed with this harsh condition.

"As for how you should practice," Feng Yao took out a scroll of blueprints from his soul guide, "I will make a special zither for you in the style of 'Fuxi'. You only need to learn the basic fingerings and then combine them with soul power control..."

At this point, Feng Yao's expression suddenly became serious: "But there is one thing you must remember - you must try it yourself at the beginning of the tempering. Once you can accurately control the intensity, you can do it for others. Otherwise..." His eyes were solemn, "you will not be able to temper the body, but will instead suffer internal injuries."

Dugu Bo nodded solemnly, his skinny fingers rubbing unconsciously, his eyes flashing with complex light: "At this age, I never thought that these nobles' pretentious things could contain such a mystery."

Feng Yao smiled faintly upon hearing this. The morning light filtered through the mist of his Yin-Yang Eyes, casting a dappled shadow on his handsome face. "Three thousand great ways, all different paths lead to the same destination." His fingertips gently plucked the strings of his zither, producing a clear, trembling sound. "Just like this spring water, seemingly opposite in both cold and hot qualities, yet here they complement each other, nurturing countless natural treasures."

Dugu Bo's gaze followed Feng Yao's, landing on the confluence of Yin and Yang in the Yin-Yang Eye of Ice and Fire. A complex ripple formed in his emerald eyes. The world only knew him as the "Poison Douluo," a ferocious and infamous figure. But who knew that, in order to suppress the poison within his body, he had also attained the pinnacle of medical prowess? Otherwise, how could he have survived this long, plagued by this poison?
Suddenly, Feng Yao looked at the various immortal items beside the Yin-Yang eyes of Binghuo, smiled at Dugu Bo and said, "Then I would be disrespectful to refuse."

As Feng Yao spoke, he had already deftly collected the Acacia Heartbreak Red and the Black Stone at its root into his bag. Dugu Bo watched his deft movements, and the corners of his dry mouth couldn't help but twitch.

"Senior, this..."

“Put it in a jade box.”

“This one.”

“This one.”

“And this one.”

As Feng Yao pointed at various rare herbs, Dugu Bo's expression grew increasingly grim. Until Feng Yao stopped in front of a large purple chrysanthemum—"I want this one too."

The chrysanthemum was a vibrant purple, its petals furry and adorable. The entire flower was seamless, yet strangely devoid of any fragrance. The most striking feature was the towering pistil in the center, its tip gleaming with a faint golden glow.

Dugu Bo narrowed his eyes and said, "You little brat, you want this thing even though you don't know what it is? You're not asking for it just because it looks good..."

Feng Yao replied calmly, "The Qirong Tongtian Chrysanthemum is a fairy-grade herb. Taking it can open up all the limbs and bones, and cultivate an indestructible body."

"You actually know him?!" Dugu Bo's pupils shrank slightly, and then a strange expression appeared on his face. "Is Juhuaguan's martial spirit so powerful?"

"Juhua Pass?" Feng Yao blinked in puzzlement.

Dugu Bo took a step closer and lowered his voice: "Boy, do you think this thing can really make you indestructible?"

"Indeed." Feng Yao nodded, then changed the subject, "But you can't use it. This item is a pure Yang immortal product, and snakes are Yin."

When Dugu Bo heard this, Yue Guan's charming face immediately appeared in his mind, and his expression suddenly became wonderful. He muttered to himself: "No wonder he can be with that old ghost..."

At this moment, Dugu Bo suddenly tugged at Feng Yao's sleeve, showing a rare sense of embarrassment: "Boy, you have taken so many. Do you have anything suitable for Yanyan?"

Feng Yao shook his head slightly and said seriously, "You should know this better than me. Sister Yan already has a blood poison in her body. If she takes tonics rashly, it might backfire and cause the poison to backfire."

Feng Yao was not a selfish person. Although he was well aware of the miraculous effects of these immortal products, he did not dare to let Dugu Bo and his grandson try them rashly. After all, the toxins in their bodies were too special, and the slightest carelessness could lead to unpredictable consequences.

Dugu Bo nodded in agreement, his eyes sweeping over the treasures in the garden with a complicated expression. If he wasn't worried about the poison in his body, why would he guard such a treasure mountain and not dare to try it easily?
"Although most immortal products are not suitable for you and Sister Yan, these two will be of great benefit to you." Feng Yao said, pointing to the Youxiang Qiluo immortal product and the Bloody Swan Kiss not far away. Dugu Bo's eyes flashed: "How do I use it?"

Feng Yao carefully held up the pink fragrant Qiluo fairy product and said, "The fragrance of this thing can ward off all poisons. Even your green phosphorus snake venom can't hurt me at all."

To verify, Dugu Bo flicked his fingertips, sending a wisp of emerald green poisonous mist drifting towards Feng Yao. Suddenly, the fragrant Qiluo immortal product erupted in a soft pink light, enveloping Feng Yao. The poisonous mist melted away as ice and snow met fire upon contact with the pink light.

"Interesting!" Dugu Bo, intrigued, gradually increased his poison output. However, no matter how much poison he released, he couldn't break through the seemingly delicate pink halo. A rare look of amazement crossed the Poison Douluo's face. "What a great Poison Slayer!"

"This thing will be of great benefit to your research on pharmacology." Feng Yao handed over the magic herb with a smile.

Dugu Bo took it with great care and said, "Thank you for your kindness."

"What about this one?" He pointed impatiently at the enchanting blood-red swan kiss.

Feng Yao's expression suddenly became serious. "You must be extremely cautious with this thing. It's harmless to ordinary people, but it can increase its toxicity a thousand times."

Before he finished speaking, Dugu Bo's eyes flashed with a terrifying glint. If he had gotten this thing earlier, Yue Guan would have been killed by him long ago.
"Please don't..." Feng Yao was halfway through his words when Dugu Bo's face turned as black as the bottom of a pot.

"You little bastard!" Dugu Bo shouted angrily, "When I was playing with poison, you were still sucking milk!"

Dugu Yan, who was standing by, couldn't help but cover her mouth and chuckle.

Feng Yao couldn't help laughing, but saw that Dugu Bo had carefully put the Blood Swan Kiss into a special jade box as if it were a treasure, and his movements were so gentle as if he was treating a priceless treasure.

Feng Yao carefully put the jade boxes containing the immortal items into the soul guide. When he collected the last one, his eyes involuntarily fell on the two most dazzling immortal items in the center of the Yin-Yang Eye of Ice and Fire.

"Kid, is it time to stop?" Dugu Bo breathed a sigh of relief upon seeing this, thinking that this kid would finally stop.

Feng Yao gave a flattering smile: "Senior, I'm afraid I need your help with the last two. They must be taken on the spot."

Dugu Bo followed his gaze, and his emerald green pupils suddenly shrank: "You are not planning on those two plants, are you?" He pointed at the ice-blue Eight-Angled Ice Grass and the fiery red Fiery Apricot in the center of the spring, and his voice rose eight octaves.

Feng Yao nodded, his eyes gleaming with excitement. "That's right. These two immortal products are extremely poisonous if taken alone, and the meridians will be instantly destroyed by the powerful force of ice and fire. But if taken together..." He pointed to the mingled spring water, "Just like this Yin-Yang Eye of Ice and Fire, the yin and yang complement each other, not only can you cultivate a body that is immune to all poisons, but you can also temper your body with the power of ice and fire."

Dugu Bo had felt the power of ice and fire suppressing the poison, and he couldn't help but be moved. He sighed softly, "What a pity this opportunity is missed, but it's a good opportunity for you."

"Actually..." Feng Yao hesitated for a moment, "Sister Yan can also take it. This may be a radical cure, able to completely wash away the toxins in her body and greatly improve her physical fitness. However..." He paused, "While being immune to all poisons, it also means that her future toxins will no longer be able to increase."

Dugu Bo's face shifted after hearing this. After a long pause, he shook his head and said in a low voice, "What's the difference between a snake without fangs and a loach?"

Feng Yao remained silent. He understood that for the Dugu family, poison wasn't just a means to an end; it was a legacy. Just like his zither playing, it wasn't just a skill; it was a part of his soul. As a Titled Douluo, Dugu Bo naturally harbored the desire to pass down his legacy.

"Tell me, how can I help you?" Dugu Bo said in a deep voice.

"Please use your soul power to capture the two immortal products at the same time. When their auras blend together, I can take them." Feng Yao said with a smile.

Upon hearing this, Dugu Bo didn't hesitate. With a flick of his bony fingers, two sharp blades shot out like blades, precisely severing the roots of the two immortal herbs. In an instant, a surge of Titled Douluo spirit power swept out, steadily lifting the two immortal herbs and suspending them in front of Feng Yao.

The snow-white Eight-Angled Ice Grass had eight crystal petals that looked like ice sculptures, and the pistil in the center was flashing with a biting cold light; while the other fiery red Fiery Apricot looked like a cabbage, but it exuded a scorching breath, as if it would burst into flames at any time.

Feng Yao took a deep breath, stretched out his hands like lightning, and at the moment when the two completely opposite auras converged, he put the two immortal herbs into his mouth at the same time.

"boom--"

The terrifying energy of ice and fire exploded within his body. Feng Yao's face instantly twisted, a fine frost forming on the left side of his face while the right side flushed crimson. His body trembled violently, as if two giant dragons were tearing and battling beneath his skin.

"Grandpa! Xiaofeng he--" Dugu Yan exclaimed and subconsciously stepped forward.

"Don't worry," Feng Yao squeezed out a few words from between his teeth, his voice hoarse as if it had been burned by ice and fire, "I need to borrow spring water to neutralize it."

Before he finished speaking, he jumped and immersed himself in the magical spring water of the Yin-Yang Eye of Ice and Fire.

Beneath the spring, Feng Yao's body became a brutal battlefield. The twin energies of extreme cold and heat clashed frantically through his meridians, each encounter bringing excruciating pain. Even more terrifying, his physique, tempered by the sound of the zither, prevented him from fainting, forcing him to endure this inhuman torture with conscious awareness.

His skin sometimes formed a thick layer of ice, sometimes burned brightly; his bones crackled under the strain of alternating heat and cold; his internal organs felt as if being pierced by thousands of steel needles. In this torment worse than death, Feng Yao clenched his teeth tightly, blood seeping from the corners of his mouth.

After an unknown amount of time, when the two energies finally began to slowly merge, Feng Yao's consciousness finally collapsed and he fell into a deep coma.

Dugu Bo stood by the spring, his hands behind his back, his dark green robe rustling in the wind. He gazed into the rippling Yin-Yang Eyes of Ice and Fire, a flicker of fear in his eyes.

"This kid is really bold." He murmured in a low voice, with amazement and a hint of imperceptible admiration in his voice.

The ripples in the spring gradually subsided, reflecting Dugu Bo's complex expression. He subconsciously glanced at his granddaughter beside him, secretly thanking himself for not letting Yanyan try such a dangerous method. Even with his experience as a Poison Douluo, he was shocked by the terrifying energy fluctuations that had just erupted from Feng Yao.

Dugu Yan nervously clutched the corner of her clothes, her emerald eyes fixed on the calm water: "Grandpa, is he really okay?"

Dugu Bo snorted lightly and stroked his beard pretending to be calm: "Don't worry, that kid is very smart." Having said that, he actually didn't know whether Feng Yao could come up alive.
