Ice and Fire Yin-Yang Well

Dugu Bo was taken aback.

He looked deeply at Wang Dong'er. Instead of the anger one might expect when a secret is exposed, he asked with unusual calm.

"How did you know?"

"For soul beasts like the Jade Phosphor Serpent, even the blood flowing through their veins is highly toxic. When such a venomous soul beast serves as a martial soul, the practitioner is bound to be backlashed by the toxins produced by the martial soul during cultivation. Senior Dugu Yan is one such example. As her grandfather, and with the Jade Phosphor Serpent Emperor as your own martial soul, how could you possibly be immune to that venomous backlash?"

Wang Dong'er spoke up.

"To be honest, Poison Douluo, any normal person would realize you are riddled with potent toxins."

"After all, what normal person has pupils and hair of such... unique colors, while also emitting a faint, fishy stench?"

"It is only because you are the Poison Douluo, the world-renowned number one poison master in the soul master world, that no one would ever suspect you are suffering from such severe poisoning."

Dugu Bo gave a bitter smile.

He had made his name through poison, roaming the soul master world with impunity. The world feared him, and even poison-attribute soul beasts gave him a wide berth.

The irony was that he could not control the venom of his own martial soul.

The more he tried to force control, the more agonizing it became.

"Poison is my craft, and poison is my constant companion. After so many years of cultivating poison arts, my body is riddled with holes; the serpent venom and my blood have almost completely fused. If I had met you a dozen years earlier, your methods might have truly been able to suppress the venom in my body."

Dugu Bo sighed.

"It doesn't matter anymore. As long as Yan Yan doesn't suffer from the venomous backlash, that is enough. Little girl, as long as you are willing to help my granddaughter suppress her venom periodically, I... can reluctantly take you as my disciple."

You want to take all the credit for yourself, don't you...

Wang Dong'er muttered to herself in her heart.

"There is no need for any master-disciple formalities. After all, I am not walking the same path as you, Senior."

"Besides, it is not as if the venom in your body is incurable. Why be so pessimistic?"

"What do you mean by that? Are you saying you have a way to detoxify me?" Dugu Bo's expression turned serious. Even if he was skeptical, hope was reignited in his heart.

"It is quite simple: you only need to transfer the toxins in your body into your soul bones. That way, the venom will backlash against the soul bones instead of your physical body."

Wang Dong'er explained.

"However, this soul bone detoxification method has a major drawback. Soul bones have a limit to what they can withstand. If the transferred toxins exceed that limit, the venom will erupt, and not even a god could save you. This method treats the symptoms, not the root cause."

Hearing this, Dugu Bo pondered for a moment and suddenly realized that what Wang Dong'er said made perfect sense.

He wanted to experiment immediately. What did it matter if this soul bone method had drawbacks? As long as he could stop suffering from the torment of the venom, it would be enough. He hadn't slept soundly in fifty or sixty years. Even if this method was inferior, it was a lifesaver.

"I have another detoxification method, one without those drawbacks, but... it requires several precious medicinal herbs."

"Precious medicinal herbs? That is easily arranged!"

Dugu Bo had originally intended to make do with the soul bone method, but now that a better solution was on the table, he was naturally overjoyed.

Before Wang Dong'er could react, her vision blurred, and she was instantly transported a hundred meters into the air.

The scenery on the ground shifted rapidly. The vast Royal Academy became tiny, and the people of Heaven Dou City looked like mere ants. In less than half an incense stick of time, Dugu Bo had brought her to the Sunset Forest.

When Wang Dong'er's feet touched the ground, she had arrived at the core of the forest, inside Dugu Bo's herb garden.

Dugu Bo's speed was simply too fast; the adrenaline of Wang Dong'er's rapid ascent had barely peaked before it subsided.

Ahem, do not misunderstand; I am referring to his flight speed.

The spiritual energy of heaven and earth here was over ten times denser than in the outside world. After just two breaths, Wang Dong'er felt a bit dizzy, a sense of being intoxicated by soul power rising within her, as if the spiritual energy outside were merely inferior, man-made imitations...

She turned her head to look into the distance. In the center of a cluster of exotic flowers and rare herbs lay a pool of water, split into two distinct colors—ice and fire—that stood in stark contrast, neither encroaching upon the other.

Finally, she had arrived...

"This is my herb garden. Every precious herb, common or rare, can be found here. Everything here is yours to take!"

Dugu Bo pointed toward the Ice and Fire Yin-Yang Well.

"However, you must be careful. That spring water is incredibly potent; even I dare not linger near it for too long. You would do best to walk around it."

"And those exotic flowers and herbs growing around the spring—even I do not know what all of them do. You had best not touch them randomly."

"Wang Dong'er, as long as you can help me detoxify, I, Dugu Bo, will agree to any condition you set. I would even be honored to become your sworn sibling. Even if you cannot, I will still be very grateful. Do not feel burdened; just do your best."

"Poison Douluo, if I only had a fifty percent certainty of success before, now I can say with absolute confidence that I can cure your poison. Not only can I cure it, but I can also help you refine your poison arts, break through your current limits, and grant you a second spring of vitality... ahem."

Dugu Bo looked at Wang Dong'er with a strange expression. "So, you were just playing with me when you said you could cure it earlier, weren't you?"

"Tell me, why are you now one hundred percent certain you can succeed?"

"Senior, do you know what that spring is? It is called the 'Ice and Fire Yin-Yang Well,' one of the three great treasure basins in the world!"

Wang Dong'er led Dugu Bo toward the Ice and Fire Yin-Yang Well, introducing it to him as they walked.

"The ice and fire spiritual energy produced by the Ice and Fire Yin-Yang Well not only promotes the circulation and absorption of soul power and suppresses all poison attributes, but it also accelerates the growth of plants and animals by several hundred times."

"That is indeed true." Dugu Bo nodded. "Without this... Ice and Fire Yin-Yang Well, I fear I would never have broken through to become a Title Douluo, and whether I could have survived until now would be a question."

"The poisonous herbs and medicinal plants I cultivate near this spring grow dozens of times faster; it is quite exaggerated. I never imagined you would know so much."

"Books contain houses of gold; one naturally knows more by reading more," Wang Dong'er continued.

"The exotic flowers and rare herbs growing beside this spring are even more extraordinary."

"They can be collectively referred to as immortal-grade medicinal herbs."

Wang Dong'er pointed to a brilliant golden, fuzzy chrysanthemum as an example. "This flower is named the Heaven-Reaching Chrysanthemum. After consuming it, one's qi can flow through all four limbs and eight meridians, forging a body as indestructible as diamond!"

"Every single immortal-grade herb possesses unexpected, heaven-defying medicinal properties. While their effects differ, I cannot guarantee how many levels your soul power will increase by after absorbing the one suited to you, but it will certainly elevate your talent and potential ceiling."

"Simply put, every immortal-grade herb beside the Yin-Yang Dual Crystal Spring has the effect of defying the heavens and changing one's fate."

Dugu Bo froze in place, his eyes wide, pupils trembling uncontrollably, his mouth agape in a large "O" shape.
