Chapter 5 Cooperation and Conditions

The next day, at the entrance to the Monster Mountain Range.

Under the shade of a tree, a simple gray tent was set up, and a long line had already formed in front of it. Most of the people in the tent were mercenaries, with new or old wounds on their bodies. Some were covering their wounds with blood-soaked bandages, while others were grimacing and pressing their bruises.

Before the wooden table, a woman in a pale white dress stood, the simple fabric highlighting her snow-white skin. She wasn't exactly a stunning beauty, but she possessed a captivating charm—gentle eyes and a faint smile playing on her lips as she gently cleaned the wounds of the mercenary before her.

“Little Fairy Doctor, my arm…” A mercenary with a full beard was about to speak when she gently interrupted him.

"The wound is covered in rust; it needs to be cleaned first." Her voice was clear and cold as she dipped her fingertips in the medicinal powder and skillfully pressed it onto the wound. The mercenary gasped, but managed to suppress a howl, muttering with a flushed face, "Much better than that quack Black Fang..."

Not far away, a figure in black robes slowly walked from the direction of Qingshan Town.

He stood on the periphery of the crowd, his gaze passing over the throng of heads and landing on the woman.

"Looks like you still don't trust me..."

The murmur faded with the wind. He raised his hand to adjust the hood of his cloak, a faint smile playing on his lips. The smile didn't reach his eyes; instead, it carried a hint of helplessness and understanding.

Without pausing, he walked directly towards the location of Little Fairy Doctor.

Although his steps were light, his outstanding demeanor made him stand out in the queue.

"Who are you?"

"How dare you cut in line!"

Several burly mercenaries, their faces contorted with menace, immediately surrounded them, veins bulging on their thick arms. One of them, hot-tempered, had already clenched his fist, but froze on the spot the next second—

A layer of dark, ethereal gauze silently covered the figure in black robes, gleaming coldly in the morning light.

The crowd, which had been filled with righteous indignation, immediately fell silent.

Lu Yu walked quickly past the queue and stood in front of Little Fairy Doctor, with the mercenaries beside him making way for him.

He stopped in front of the wooden table, his eyes flickering, and looked at the Little Fairy Doctor who was still busy preparing medicine. He said in a low voice, "The way you're doing this doesn't seem like you're coming with sincerity."

Little Fairy Doctor smiled calmly, her hands continuing their work.

She poured the last ingredient of powder into the porcelain bowl before raising her eyes. Her clear eyes looked directly at Lu Yu, a gentle yet distant smile on her lips: "I am the face of Wan Yao Zhai. If you want me to come to the entrance of the Monster Mountain Range alone while hiding my identity, Wan Yao Zhai cannot agree to that."

Lu Yu was taken aback, then shook his head.

He then realized his oversight; the seemingly frail woman in front of him was no longer an ordinary person who could move around freely in Qingshan Town.

"It was I who didn't think things through properly."

His fingers, hidden beneath his black robe, gently rubbed together. Then, with a serious expression, he said, "In that case, let's find another quiet place to discuss this further."

Little Fairy Doctor handed the medicine packet to the waiting mercenary, patted the powder off her hands, and calmly stood up: "I have a secluded house in Qingshan Town. You can go there."

……

Soon after,

In a courtyard house in Qingshan Town.

Lu Yu followed Little Fairy Doctor into an elegant room. The room was simply furnished but exceptionally clean, and the air was filled with a faint fragrance of herbs.

"Please take a seat."

The Little Fairy Doctor skillfully tidied up the medicine bottles on the table, took out two celadon teacups, poured water into them, and gestured for Lu Yu to sit down.

Lu Yu sat down at the table, looking directly at Little Fairy Doctor who was making tea, and went straight to the point: "You should have read the Seven-Colored Poison Scripture, right? You must also know the fate of the Calamity Poison Body." He stroked the teacup, not intending to drink it, and continued: "I have a way to help you get rid of this fate. But before that, you need to agree to one condition."

The Little Fairy Doctor paused slightly as she poured tea. A flicker of emotion flashed in her eyes when she looked up, but she quickly regained her composure: "If it can truly help me control this innate poisonous body, I would agree to any condition, let alone one, even a thousand."

"Tell me about it." She put down the teapot, her expression focused.

Lu Yu said solemnly, "I have a special cultivation technique that can help you control the Calamity Poison Body. However, after cultivating this technique, you will be subject to my control." He paused, "But the advantage is that if we cultivate together using this technique, we can achieve twice the result with half the effort."

"If you are to cultivate this technique, you must agree to my condition: when I need you, you must cultivate with me."

pat!

The teapot slipped from the little fairy doctor's hands and shattered on the ground. The scalding tea splashed onto the hem of her skirt, and her fair cheeks instantly turned bright red.

"Shameless!" she glared at Lu Yu through gritted teeth. "You men are all the same!"

Lu Yu quickly explained, "You misunderstood. This cultivation method has two volumes, Yin and Yang. I cultivate the Yang volume, and you cultivate the Yin volume. This is a characteristic of the cultivation method itself."

However, while Lu Yu's explanation was sincere, it cleverly avoided the most crucial point—the Yin scroll of the Great Floating Pagoda Technique could never escape the control of the Yang scroll. Of course, if their friendship deepened in the future, he might consider teaching the complete technique, but for now, necessary precautions were still necessary.

Little Fairy Doctor's chest heaved violently as she suppressed her anger and asked, "Is there... really no other way?"

"At least I don't have it right now." Lu Yu said calmly. "Trust me, and I can give you the cultivation technique right now; if you don't, we can part ways amicably."

He added calmly, "You're not the only one in the world with a special physique. I'm just giving you a choice. If you don't cultivate, it won't cost me anything."

"You!" Little Fairy Doctor trembled with rage, her red lips almost bleeding from being bitten. This bastard is utterly shameless!
After a long silence, she finally said dejectedly, "First... let me see the contents of the cultivation technique."

Lu Yu raised the corners of his mouth slightly, then took out a jade slip and said, "I have copied the true meaning of the cultivation technique into the inheritance jade slip. Take your time to look at it."

After a while,

In the flickering candlelight of her boudoir, the slender fingers of the woman in white gently turned the pages of a jade slip. As she deepened her understanding, waves of emotion stirred in her clear eyes.

"This……"

Despite her limited knowledge, the profound and mysterious meaning contained within the Yin Scroll of the Great Floating Pagoda Technique still deeply moved her. Every character seemed to contain the ultimate truth of heaven and earth, and every incantation was extremely profound.

Based on her limited understanding, this was at least... an Earth-rank cultivation technique?
"finish watching?"

Lu Yu smiled and spoke gently.

Little Fairy Doctor raised her head, her complex gaze lingering on the young man's face for a long time. Only now did she truly begin to believe what the young man had said—the value of this cultivation technique was so great that even a Dou Huang powerhouse would be eager to possess it.

"why?"

Her voice trembled slightly, and her plain white sleeves clenched unconsciously. She was merely a woman cursed by the cursed Poison Body; what virtue or ability did she possess to deserve such a generous gift?

"What do you mean, why?" Lu Yu spread his hands, looking completely bewildered. "Wasn't it clearly explained? Of course, it's for dual cultivation!"

"you!"

Little Fairy Doctor suddenly looked up, her fair cheeks instantly flushing red. She glared at the outspoken young man before her, embarrassed and annoyed, but when she met his open gaze, her momentum involuntarily weakened.

"I...I understand." She turned her face away in a panic, her voice barely audible. "I promise you. Now...please leave first, I need to start practicing my new cultivation technique."

As she spoke, she reached out to push Lu Yu away, but the moment she touched his sleeve, she recoiled as if burned. In the candlelight, her face was as red as a boiling teapot.
