Yin-Yang Dual Poison? Yu Nan Teaches the Method of Poison Pills? Using Dugu Yan's Blood!

Immediately following this, the trunk in the center began to rot and liquefy at a speed visible to the naked eye under the erosion of the purple-gold poisonous gas.

The extreme cold made the wood brittle, the extreme heat caused the fibers to snap, and the potent poison thoroughly destroyed all traces of life.

Crash!

In less than three breaths, that century-old Ironwood had been reduced to a pile of red and blue debris and pus under the pincer attack of the ice, fire, and potent poison.

Not even a single intact fragment remained!

"Hiss—"

Dugu Bo watched this scene, his molars aching as he drew in a sharp breath.

"This... what kind of tyrannical poison is this?"

"It possesses the sinister nature of cold poison, the explosive force of fire poison, and the melting properties of corrosive poison..."

"Yan Yan, with a strike like this, let alone Soul Ancestors of the same rank, even Soul Kings or Soul Emperors would meet their end on the spot if they were the least bit careless!"

Although Dugu Bo was an expert in the art of poison, he had never seen such an unreasonable mixture of toxins in his entire life.

Ordinary antidotes could neutralize the poison but could not handle the ice and fire.

Using soul power to resist the ice and fire would only allow the potent poison to seize the opportunity to invade.

This was simply an unsolvable death loop!

"Surprised already?"

Yu Nan's voice rang out at the perfect moment, carrying a hint of smugness.

"This is called the 'Yin-Yang Dual Poison'."

"From this day forward, this girl's poison is no longer a simple biological toxin, but an elemental poison containing the laws of heaven and earth."

"Unless the opponent possesses an ultimate attribute or has the soul power of a Title Douluo to resist it head-on, she will be invincible among her peers and capable of killing those of higher ranks as easily as reaching into a bag to take an item!"

Dugu Yan looked at her own hands, her eyes filled with wild joy.

She could feel that not only had her attack power increased.

More importantly, the faint, lingering pain she used to feel in her body whenever she used the Jade Phosphorous Serpent poison had completely vanished!

She was now like a perfect vessel, capable of containing and releasing this terrifying toxin without any restraint.

"Alright, the first stage of the girl's special training is successfully completed."

Yu Nan changed the subject, his translucent phantom drifting before Dugu Bo, looking at him with a half-smile.

"Old Poison Freak, you enjoyed watching your granddaughter get stronger, didn't you?"

"Now, it's your turn."

Dugu Bo shuddered, the excitement in his eyes instantly replaced by trepidation.

Dugu Bo looked at the churning red and white Ice and Fire Yin-Yang Well, then at his own aging bones, and swallowed hard, offering a bitter smile.

"S-Senior... you wouldn't be asking this old man to strip naked and jump in there, would you?"

"Yan Yan had those two immortal herbs to protect her body, but this old man does not. Besides, at my age, if I were to jump in, I fear I would be cooked through instantly..."

"What are you thinking?"

Yu Nan rolled his eyes.

"Those two immortal herbs were peerless, one-of-a-kind treasures; once consumed, they are gone. Furthermore, the toxins in your body have accumulated for decades and have long since seeped into your bone marrow. If you really jumped in, the medicinal power of the herbs wouldn't even have time to dissolve before you were blown to pieces by the backlash of the toxins within you."

"Then... what does Senior mean?"

Dugu Bo asked cautiously.

"The method to cure you lies with your granddaughter."

Yu Nan pointed at Dugu Yan.

"She has now cultivated the Ice and Fire Golden Body; her blood is the best antidote in this world. It is also the only key to suppressing the backlash within your body."

"Yan Yan's blood?"

Dugu Bo was stunned.

"That's right."

Yu Nan's expression turned serious as he began to impart the true technique.

"Dugu Bo, the reason you suffer from the backlash of your poison is that your toxins are too mixed, too chaotic, and are leaking uncontrollably into your limbs and bones."

"What I am about to teach you is the method of the 'Poison Pill'!"

Yu Nan was a 200,000-year-old Poison Dragon.

He possessed vast experience regarding poison pills.

Referencing the detoxification method Tang San had once given Dugu Bo in his memories, he devised the most suitable method for Dugu Bo to condense a poison pill.

Within Dugu Bo's body, there already existed a poison pill that carried half of his poisonous cultivation.

With Yu Nan's guidance to condense a Life-Bound Poison Pill, this dilemma would resolve itself.

"You need to use Yan Yan's blood as a catalyst, utilizing the extreme ice and fire energy contained within it."

"Forcefully compress and purify the chaotic poisonous cultivation currently inside your body!"

"Drive all the poison into your dantian and condense it into a 'Life-Bound Poison Pill'!"

"Once the poison pill is formed, your poisonous cultivation will be completely under your control and will no longer backfire on you."

"Furthermore, your soul power will become much more refined due to the purification of the toxins."

Having said this, Yu Nan paused, casting out the final bait:

Dugu Bo listened, his heart surging with emotion, his fists clenched tight.

The nightmare that had plagued him for most of his life, the curse that had tortured his son to death.

Finally... was it finally going to end today?

"Yan Yan, lend Grandfather some blood."

Dugu Bo looked at his granddaughter, his eyes complex.

"Grandfather, don't just say some—take as much as you need!"

Dugu Yan didn't hesitate, raising her wrist and slicing it with a flick of soul power from her fingertip.

Ding!

A crisp sound rang out.

Dugu Yan awkwardly realized that the Ice and Fire Golden Body she had just mastered was too tough; her soul power hadn't even broken the skin.

"..."

Both Dugu Bo and Yu Nan fell silent for a moment.

"Ahem, use more force."

Yu Nan reminded her.

Dugu Yan's pretty face flushed red. This time, she increased her strength and finally managed to cut a gash into her fair wrist.

Bright red blood flowed out, emitting a faint, refreshing fragrance. Within the blood, red and blue halos of light faintly swirled, appearing extraordinarily miraculous.

Dugu Bo no longer hesitated; he took a deep breath and sat cross-legged.

He took the blood his granddaughter offered, swallowed it, and then formed hand seals, beginning to guide his internal soul power according to the mantra Yu Nan had taught him.

"Sink your qi into your dantian, hold your essence and guard the one!"

"With blood as the guide, let ten thousand poisons return to their origin!"

Following Yu Nan's sharp shout.

Dugu Bo's body instantly turned emerald green, and thick, toxic mist erupted from every one of his pores.

The surrounding grass was instantly corroded into scorched earth.

An expression of extreme agony appeared on his face; clearly, forcing out toxins that had seeped deep into his marrow to condense them was an excruciating process.

But Dugu Bo gritted his teeth hard, not making a sound.

For his granddaughter, for the Dugu family.

And for his own dignity as a Title Douluo!

This bit of pain was nothing!

Yu Nan floated to the side, monitoring Dugu Bo's state at every moment while splitting off a wisp of mental energy to protect Dugu Bo's heart meridian.

This Old Poison Freak, though his talent is a bit lacking, his ruthlessness is not bad at all.

Yu Nan thought to himself.

Time passed second by second.

As the ice and fire medicinal power within Dugu Yan's blood took effect, the originally violent toxins inside Dugu Bo's body seemed to encounter their natural enemy.

They began to obediently converge toward his dantian.

That terrifying emerald green hue also began to gradually fade, shrinking toward the center of his dantian.
