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

Ye Feiyan sat on Li Hanshan's lap, her whole body stiff as a piece of wood.

Li Hanshan was in no hurry. He raised his hand and slowly brushed the wet hair that clung to her cheek, his fingertips brushing against her earlobe and chin, finally stopping at her fair neck, gently caressing it—as if playing with a newly acquired object.

"Why are you trembling?" he asked with a smile. "Didn't you just say you were going to make me feel good?"

"...I wasn't trembling." Ye Feiyan bit her lip, forcing herself to soften, raised her arms to wrap around his neck, buried her burning face in the crook of his neck, and said in a soft, sweet voice, "Hold me."

Li Hanshan raised an eyebrow and, as instructed, put his arm around her waist.

The body in his arms was cool, and through the soaked fabric, he could feel her slender shoulder blades, rising and falling gently with her deliberately softened breathing. His fingers slid slowly down her back, neither too light nor too heavy, and wherever they touched, her body trembled uncontrollably.

Ye Feiyan looked up.

In the flickering candlelight, she kissed him again. This time, she was a little more careful; her lips weren't so taut, but they were still a bit awkward. As their lips met, their breaths became erratic, and their teeth brushed against each other again.

Li Hanshan chuckled softly.

Before the laughter had even subsided, her sash had come undone. Her inner garment slipped down, revealing one of her snow-white shoulders, where two faint sword marks clung—left from traversing the ravine of sword energy. He reached out and touched the mark, and she flinched slightly, a fleeting glint in her eyes before being obscured by a glistening tear.

No one knew that as she obediently nestled in this man's arms, a sinister scripture was silently circulating deep within her consciousness.

The Demon Seed.

This was one of the most treasured techniques her father had passed down to her, derived from the "Demon Seed of the Dao Heart," a closely guarded secret of the Heavenly Demon Sect—using her body as bait and the fusion of their souls as a bridge, at the most intense moment of intercourse, a demon seed was transferred into the other person's body along with their semen. The demon seed was formless and intangible, specifically designed to erode the soul. Within seven days, the person afflicted would unknowingly become the demon slave of the one who planted it, obedient to their every command, and unable to control their own life or death.

Her father had said that this was her last lifeline.

The reason she is now so obedient to Li Hanshan is because she has been waiting for this moment. The more he becomes obsessed, the wider the gates of his soul will open—that is the perfect time to plant the demon.

She was genuinely nervous. Her heart was pounding, her fingertips were cold; this was the first time she had given herself to someone else.

The anticipation was real. She had even mentally rehearsed the scene seven days from now: this man kneeling at her feet, releasing her from the Heavenly Demon Seal, stopping Yin Yue for her, and opening the path back to Zhongzhou for her—

The candlelight went out silently.

That night, the candlelight in the hold never came on again.

-

After an unknown amount of time, in that deepest moment, Ye Feiyan's eyelashes trembled violently, and the scripture that had been circulating in the depths of her consciousness for half the night suddenly came to an abrupt halt—a wisp of pitch-black demonic seed, following the intertwined souls, silently passed through.

Become!

She almost burst out laughing. Months of pursuit and humiliation, and the hatred for the destruction of the Heavenly Demon Sect—all culminated in this night, with interest!

Then, the demonic seed entered the other party's soul.

Like a clay ox sinking into the sea.

There was no response, no taking root, no echo of her soul opening as she had anticipated. The demonic seed that embodied all her hopes vanished with a "whoosh," like a drop of water falling into a red-hot iron pot.

Immediately afterwards, an irresistible suction force swept back along with the intertwined breaths of the two.

Within Li Hanshan's body, the "Yang Book," which never needed deliberate activation, quietly began to operate. Deep within his meridians, a slowly rotating vortex silently opened, barely blocking the embers of the demonic seed. Then, it began to draw in the demonic essence at a slow but relentless pace, following the bridge of their intertwined souls.

Ye Feiyan didn't know what it was.

She could only feel that her already depleted spiritual energy was flowing into the other person little by little—she couldn't take it back.

She panicked. She wanted to stop, but once the "Demon Seed Induction" was activated, it couldn't be stopped until dawn.

For her, the rest of that night was torture.

For Li Hanshan, it is a tonic.

-

The next morning, as the first rays of sunlight streamed through the porthole into the lower deck, Ye Feiyan was huddled in a corner, hugging her knees, silently weeping.

She wasn't immune to hardship. She was hunted down for months, had the Heavenly Demon Seal implanted in her, and had her wrist broken, but she gritted her teeth and didn't cry—those were defeats, those were fate, and she accepted them.

But this night was different. She staked her last possession: her innocence, her dignity, and the demon seed she thought would be enough to turn the tide.

As a result, he lost everything.

She could clearly feel that her cultivation level had dropped slightly again. That wicked cultivation technique had used her dwindling spiritual energy as nourishment for the other party.

"Why are you crying?"

A refreshing voice came from beside me.

Li Hanshan was already dressed and stood in the morning light through the porthole. His brows were relaxed, and his aura was full and harmonious—the injuries he sustained in the battle with the Heavenly Demon Sect had almost completely healed, and even his cultivation had subtly improved by a fraction.

He looked down at the woman huddled in the corner, then squatted down with a smile.

"What you used last night, was it the Heavenly Demon Sect's technique?" His tone was like commenting on a dish. "The demonic seed tasted good, but the portion was a bit small. Next time you want to kill me, remember to plant a few more."

Ye Feiyan's crying stopped abruptly.

She abruptly raised her head, tears still streaming down her face, and for the first time, her peach blossom eyes were filled with genuine fear—he knew. He had known from the very beginning.

"You... what kind of monster are you...?"

"Your master." Li Hanshan stood up, casually pulling the blanket that had slipped down to her waist back up, his tone as casual as if he were instructing a pet, "Go back to sleep, we'll continue tomorrow."
