I'll make you the furnace and the cauldron, so you can refine Yin and Yang and prove the Great

The airship flew smoothly in the night sky, its silvery-white light flowing endlessly along the edges of the ship's gunwale, reflecting the clouds on both sides into a flowing silvery-white expanse.

As Li Hanshan led Yin Lingyue into the cabin, the spirit lamps inside automatically turned on, casting a warm yellow glow that enveloped the small space in a gentle, warm light.

Yin Lingyue tensed slightly for a moment the instant his palm touched her waist, then slowly relaxed like ice being warmed by a gentle current. She turned her head, her dark purple eyes gleaming warmly in the light of the spirit lamp, her gaze lingering for a moment on the still-unresolved spiritual energy fluctuations around him.

She finally couldn't help but ask, "Your cultivation level... is it at the peak of the Nascent Soul stage?"

Li Hanshan sat down on the edge of the bed, leaning against the cabin wall. Pure Yang energy slowly circulated through his meridians, and he spoke casually, as if he were talking about something insignificant: "Hmm."

Yin Lingyue paused. She stood by the bed, her dark purple hair gleaming softly in the light of the spirit lamp, her once cool and aloof face now showing signs of turmoil.

She had been in the Yinquan Sect for so many years, traveling all the way from the Northern Wilderness to where she was today. She had seen countless talented cultivators, but she had never seen anyone who could advance from the early stage of the Nascent Soul realm to the peak of the Nascent Soul realm in such a short time.

"It's only been a few years?" Her voice was a little hoarse. "When you left the Hehuan Sect, you had only recently broken through to the Nascent Soul stage. It's only been a little over ten years. You went from the first level of the Nascent Soul stage to the peak of the Nascent Soul stage. You can't find another person like you in the entire Central Continent at that speed."

"Am I amazing?" Li Hanshan leaned against the cabin wall, his gaze fixed on her face, his tone carrying a sense of matter-of-fact composure, without explaining the Flowing Light Array.

Yin Lingyue stared at him for a couple of breaths. Her dark purple eyes held a seriousness that naturally flowed from her being convinced. She tilted her head slightly, and her long, dark purple hair slipped from her shoulders and fell to her chest.

After a moment, she nodded, her voice a few decibels lower than before: "Impressive."

She paused, then added, "I've been cultivating all these years, but no matter how I practice, my progress is as slow as a snail's pace."

She didn't complain when she said this; she was simply stating a fact that had been repeatedly verified: "But when I cultivate with you, the effect of one session is equivalent to several months of hard work on my own. The efficiency of that spiritual energy circulation is something that can't be caught up with through hard work alone."

As she spoke, a soft light appeared in her dark purple eyes.

She recalled the days and nights she spent cultivating with Li Hanshan. The pure yang energy surged through her meridians like a tide. Each cycle was like a spring stream compressed to its limit, softening, peeling away, and shattering the bottlenecks that had been entrenched in her meridians for months or even years.

That exhilarating feeling was a stark contrast to the way she always ended up battered and bruised during her solo cultivation. In that brief moment of recollection, a pale pink blush slowly crept onto her cheeks, spreading from her ears down to the edge of her dark purple collar.

Li Hanshan leaned against the cabin wall, his gaze lingering for a moment on her flushed cheeks, a slight smile playing on his lips: "Missed me?"

Yin Lingyue looked away, her gaze falling on the burning spirit lamp on the cabin wall. She didn't deny it. After a moment of silence, she nodded, her voice a few decibels lower than before: "Mm."

"Where do you want to go?" Li Hanshan asked.

Yin Lingyue turned her head and glanced at him. That glance held a hint of reproach; her dark purple eyes shimmered gently in the lamplight, like a deep pool into which a pebble had been thrown. "Master, you're so naughty."

Li Hanshan smiled. He didn't ask any further questions, but simply reached out and pulled her closer.

Yin Lingyue leaned forward following the force, the dark purple outer robe slipping off her shoulders with a soft rustling sound, revealing the plain white inner garment and the long, slender lines of her neck.

She raised her hand and untied the sash of her inner garment, her movements much more swift than before, without the slightest hesitation, like someone who had been starving for too long finally seeing food.

When she truly got close to Li Hanshan, the long-suppressed desire, like an undercurrent that had been unleashed, seeped into his veins from every inch of skin touched by his palm.

His pure yang energy also surged into the depths of Yin Lingyue's meridians along the point where the two met, smoothing out, gathering, and re-binding the fine burrs that had accumulated from her long-term solitary cultivation.

The spiritual energy between the two intertwined and swirled in the void, replenishing, refining, and spiraling upwards.

Yinyue walked from the bow of the ship.

She was about to knock on the door to discuss the next route with Li Hanshan when she heard a faint sound coming from inside. The sound was mostly attenuated by the cabin walls, but it still reached her ears clearly.

Her steps abruptly halted on the inside of the threshold, her calm eyes, hidden beneath the silver veil, widening slightly. She stood inside the threshold, the hem of her silver robe fluttering slightly from the residual spiritual energy seeping from the cabin.

She spat. The sound was so soft that it was almost completely drowned out by the continuous sound of spiritual energy circulating inside the cabin.

Without pausing, she turned and left, her steps quickening as she arrived, her silver-white figure disappearing at the end of the cabin corridor.

Inside the cabin, Li Hanshan naturally sensed the fluctuation of spiritual energy at that moment.

But he didn't stop, nor did he let his attention wander. He held Yin Lingyue's waist, focusing all his attention on the circulation of spiritual energy between them. He could feel his meridians becoming stronger and stronger with each continuous dual cultivation. After each cycle, the nodes that had been tempered by Yin Lingyue's primordial yin energy became denser and more stable.

The reason he was previously stuck at the threshold of the Void Refinement stage was precisely because his physical strength could not keep up with the expansion of his pure Yang primordial spirit.

Now, we can take advantage of the Yin Spirit Month to make up for our shortcomings.

Originally, his purpose in bringing Yin Lingyue with him on his way to the Immortal Alliance was to use her as a power bank.

Li Hanshan didn't hesitate to use this demoness from the Yinquan Sect, and often even stood up and kicked her.

He decided to take advantage of the time he was traveling to push his physical strength as high as possible, and once he had accumulated enough strength, he would have Yin Yue help him break through to the Void Refinement stage.

The airship continued to fly high in the sky.

Yin Yue chose an extremely high route, so high that the clouds spread out beneath her feet like an endless silver-gray sea. Occasionally, a few sparse streaks of light could be seen passing by below the clouds, the trails left by demonic cultivators patrolling or traveling at low altitudes.

The air is thin at this altitude, and the concentration of spiritual energy is much thinner than at lower altitudes, but it is safe. Ordinary cultivators cannot fly to this altitude at all, and even if they could, they would be torn apart by the gale-force winds at high altitudes.

The fierce winds surged in from all directions, like invisible blades cutting through the airship's protective shield, emitting sharp whistling sounds. However, Yin Yue was a cultivator in the late stage of the Void Refinement realm, and the silver-white protective shield on the airship's surface was enough to block all the fierce winds from the outside.

Time flies, and a month has passed in the blink of an eye.

"How can he not be ashamed at all!"

Yin Yue couldn't hold back any longer. For the past month, Li Hanshan hadn't left the cabin, spending every day doing intimate things with Yin Lingyue inside.

Every time she approached, he could hear sounds that made his face flush and his heart race.
