The following day, Lin Yan asked the academy for leave, naturally citing the reason that he needed to assist Senior Dugu Bo with some important matters. Upon hearing that it was Poison Douluo who had invited him, the dean and teachers dared not object in the slightest. Instead, they earnestly instructed Lin Yan to do his best and not to worry about his studies. After everything was arranged, on the morning of the third day, Dugu Bo quietly appeared outside Lin Yan's residence.
Without any further pleasantries, Dugu Bo flicked his sleeve, and a gentle surge of Soul Power supported Lin Yan. Then, his figure transformed into a streak of emerald light, soaring into the sky and rapidly heading towards the Heaven Dou City. The speed of Titled Douluo was terrifying; Lin Yan only felt the wind whistling past his ears, and the scenery below rushed past, blurring into a patchwork of colors.
After about half an hour, Dugu Bo's speed gradually slowed down, and he finally landed in a seemingly inconspicuous mountain range. The area was surrounded by mountains, with steep terrain, misty atmosphere, and few people.
"Stay close to me. There's a poison trap I've set up here; touching it will mean certain death," Dugu Bo warned in a deep voice. He then led the way, his steps seemingly casual yet subtly following a certain pattern, cleverly avoiding the deadly poison traps on the ground and in the air that were difficult to detect with the naked eye.
Lin Yan felt a chill run down his spine and dared not be careless in the slightest, following closely behind Dugu Bo. After passing through a dense forest of poisonous miasma and rounding several rocky mountain gullies, the view suddenly opened up before him.
It was an inverted cone-shaped valley, its entrance narrow enough for only a few people to pass side by side. Even before one arrived, an extremely strange aura rushed towards them. Half of the aura was intensely hot, as if it could scorch the soul; the other half was bone-chillingly cold, seemingly capable of freezing even thought. These two diametrically opposed energies, which should have been in conflict with each other, achieved a bizarre balance and fusion here.
Stepping into the valley, the sight before him caused even Lin Yan, who was well-prepared, to gasp in amazement.
The valley isn't very large, but it's filled with a dreamlike, ethereal beauty. Red and white, two distinct colors, form the valley's main theme. At the heart of the valley lies a peculiar spring.
The spring water is clearly divided into two parts. In the oval-shaped pool, the milky white spring water and the vermilion spring water blend together like the yin and yang fish in Tai Chi symbol, yet they do not invade each other, always separated by an invisible boundary. The fiery heat and the chilling coldness emanate from this spring water.
Around the spring, all sorts of strangely shaped plants grew. Each one exuded a rich spiritual energy and vibrant life; some were crimson red like dancing flames, some were crystal clear like ice sculptures, some were shrouded in a purple aura of immeasurable nobility, and some shone with a sharp, piercing golden light...
The air was filled with the exotic fragrance of various Immortal Herb and lingzhi mushrooms; just taking a light breath made one feel as if their Soul Power was circulating slightly faster.
"This is it." Dugu Bo's voice carried a hint of complexity. This place was both a blessed land that relieved his pain and a cage that trapped him, preventing him from leaving. "Young friend Lin Yan, look at this place. Is this the ' Ice and Fire Yin Yang Well ' you spoke of?"
Lin Yan suppressed his excitement, his gaze sweeping over the red and white intertwined spring water and the rare immortal treasures he had only seen in the original novel. He slowly nodded, his tone filled with unquestionable certainty. "That's right, Senior! The Extreme Cold Yin Spring and the blazing Yang Spring converge, yin and yang coexist, the two poles stand in opposition, it is truly the Ice and Fire Yin Yang Well! There really is such a treasure land of extraordinary beauty in the world!"
Upon receiving Lin Yan's confirmation, Dugu Bo's eyes shone with unprecedented brilliance. He rubbed his hands together excitedly. "Good! Good! It really is it! Young friend, now that this place has been confirmed, what about the treatment method..."
Lin Yan did not answer immediately, but instead pretended to be carefully investigating, walking slowly around the Ice and Fire Yin Yang Well, his gaze lingering on the Immortal Herb.
He deliberately lingered in front of several specific immortal Immortal Herb, especially the strange plant located on the edge of the blazing Yang Spring, which was fiery red all over, like burning agate, and whose surrounding air was distorted by the high temperature— the Infernal Delicate Apricot; and the plant that grew on the side of the Extreme Cold Yin Spring, whose leaves were like condensed ice crystals, exuding a chill that could freeze the soul, and whose leaves had icicle-like Octagonal Mysterious Ice Grass.
He pointed to the two Immortal Herb and said to Dugu Bo, who was following closely behind him, "Senior, please look. These two are the ' Infernal Delicate Apricot ' and ' Octagonal Mysterious Ice Grass ' that I mentioned before."
Dugu Bo followed Lin Yan's gaze and felt the Ultimate Attribute emanating from the two Immortal Herb, a hint of trepidation appearing on his face. Even as Titled Douluo who was skilled in using poison, he could clearly sense the terrifying energy contained within these two Immortal Herb.
"Truly a rare treasure!" Dugu Bo exclaimed. "Young friend, do you mean that if I consume these two Immortal Herb, I can completely eliminate the toxins from my body?"
"Exactly." Lin Yan nodded. "These two Immortal Herb Immortal Herb extremely poisonous if taken alone, but if taken at the same time, their extreme cold and heat can neutralize the deeply entangled Jade Phosphorous Serpent Emperor Poison in your body. This method is the most rapid. If successful, the toxins in your body will be completely eliminated within a few days, and there will be no more worry about backlash."
Upon hearing this, a flicker of desire flashed in Dugu Bo's eyes, but he quickly suppressed it with reason. He remained silent for a moment, then shook his head with a bitter smile, "This method is good, but the price is too high. Nine-tenths of my cultivation is tied to the venom of this Jade Phosphorous Serpent Poison. If the poison is completely removed, I, as a Titled Douluo, will likely be nothing more than a figurehead. At that time, when my enemies come knocking, how will I protect Yanyan? How will I protect myself? No, this method is unacceptable."
His choice was exactly what Lin Yan had anticipated. Lin Yan's face showed understanding and admiration at the right moment. "Senior's foresight is admirable. In that case, only the second method remains: using a high-age Soul Bone as a guide, combined with medicine, to gradually infuse the toxins into the Soul Bone."
"How long will this method take?" Dugu Bo asked with concern.
Lin Yan pondered, "Senior, the poison is too deep. The toxins have almost fused with your Soul Power, bloodline, and Soul Bone. Removing them requires extreme care and a gradual approach. Even if everything goes smoothly, with the aid of a medicinal solution prepared using specific herbs growing around the Ice and Fire Yin Yang Well, it will still take at least six months to integrate most of the toxins into your soul bone. And you will have to endure considerable pain during this process. Moreover, the prerequisite is finding a high-quality Soul Bone that is at least 50,000 years old, preferably a skull or Torso Bone, to accommodate the vast amount of potent poison within your body."
"Half a year... Soul Bone over 50,000 years old..." Dugu Bo frowned. He could wait for the time, but Soul Bone over 50,000 years old was extremely rare. Even he, as Titled Douluo, only had a ten-thousand-year-old Head Soul Bone passed down from him, which did not meet the requirement of 50,000 years.
Lin Yan also gave a method to increase the chance of getting Soul Bone: if you can't fight them, find more Soul Beast that are over 50,000 years old to fight!
"I'll find a way to deal with the Soul Bone!" Dugu Bo replied immediately. "Then, I'll leave the preparation of the medicine to you, young friend."
Lin Yan said solemnly, "Since you trust me, I will do my best. The preparation of medicine needs to be adjusted according to your physical condition, and many herbs need to be freshly picked here to maximize their efficacy. I plan to stay here for the time being to prepare the initial medicine for you and to study the subsequent treatment plan."
Upon hearing this, Dugu Bo was taken aback at first, then reminded him, "Young friend, you are very kind. However, the environment here is special, with alternating extreme heat and cold, which puts a great strain on the body. Ordinary Soul Master simply cannot stay here for long. You..."
Lin Yan smiled slightly, and the Supreme Purity Breathing Technique quietly circulated within his body. A righteous and peaceful aura, seemingly capable of encompassing all things, naturally flowed out, slightly repelling the extreme heat and cold that were invading from the surroundings.
"Senior, please rest assured. My cultivation technique is somewhat special, giving me a slight resistance to this environment. Moreover, although the environment here is harsh, the spiritual energy of heaven and earth, especially the life force suitable for Plant-type Martial Soul cultivation, is incredibly abundant. Cultivating here might be a rare opportunity for me. If senior allows, I would like to take this opportunity to cultivate here and gather some necessary herbs for preparing medicine."
Dugu Bo sensed the strange aura emanating from Lin Yan, and his eyes flashed with surprise once again.
This kid is indeed extraordinary! He pondered for a moment, thinking that Lin Yan was willing to stay in this dangerous place to treat him, and felt even more grateful and trusting.
