Dual Cultivation System: My Cultivation Was Crippled, So I Rely on Intimacy to Level Up

The Spirit Boat carved a path through the sea of clouds, its hull shimmering with a protective cyan light.

Zhou Kai was quite at ease. During the day, he basked in the sunlight at the helm, lazily guiding the boat while occasionally urging the four women to focus on their cultivation.

At night, however, the cabin became his playground with Wang Qiaoqiao.

Inside the swaying room, the air was thick with the scent of musk and sweat. Wang Qiaoqiao’s pale skin flushed a deep, inviting pink as she arched her back, her fingers digging desperately into the sheets.

“Zhou Lang… deeper…” she gasped, her voice trembling between pleasure and exhaustion.

Zhou Kai grinned, gripping her hips firmly. He drove into her with rhythmic, powerful thrusts, not just seeking pleasure, but actively circulating his technique. Every collision sent waves of Vitality coursing through their connected bodies. The “Deep Interaction” was potent; he could feel her Yin energy feeding his cultivation while his Yang essence nourished her in return.

Her charming moans filled the small space, uninhibited and loud enough to be heard by anyone awake in the adjacent rooms. She climaxed with a high-pitched cry, her body convulsing around him, milking him dry as they completed another session of Dual Cultivation.

As for Chen Ziyi and Chen Ziqing, Zhou Kai hadn’t touched them in these past twenty days. It wasn’t favoritism; he was simply calculating. He needed to raise everyone’s Spirit Roots to high-grade efficiency, and Wang Qiaoqiao’s dual Spirit Roots made her the bottleneck compared to the sisters’ medium-grade aptitude.

The atmosphere on the Spirit Boat, however, had become delicate.

Although Wang Qiaoqiao monopolized Zhou Kai’s bed every night, basking in his favor, her days were less pleasant. She often felt ostracized by the other women.

Especially Chen Ziqing.

That girl had a face that screamed innocence and fragility, yet she had mastered the art of the “Green Tea” bitch. Whenever she looked at Wang Qiaoqiao, her expression would hold a subtle, almost imperceptible trace of provocation.

Wang Qiaoqiao was no fool. She caught every barb hidden in Ziqing’s soft words and retaliated with charming smiles laced with her own thorns.

But the moment she fought back, Chen Ziqing’s face would stiffen. Her eyes would redden instantly, rimmed with unshed tears, as she looked toward Lin Zhiwei with an aggrieved, pitiful expression.

Lin Zhiwei, naturally protective, would immediately side with the Chen sisters. Over the last twenty days, seeing Zhou Kai only sleep with Wang Qiaoqiao had planted a vague seed of unease in Lin Zhiwei’s heart, subconsciously drawing her into the sisters’ camp.

Then, Chen Ziyi would step in, playing the role of the benevolent matriarch. “Family harmony brings prosperity,” she would say softly. “Sisters should live in peace.”

Wang Qiaoqiao would inwardly sneer. This ‘head wife’ never missed a chance to polish her virtuous facade.

On this boat, everyone had their own agenda. The Chen sisters were a united front, backed by Lin Zhiwei. Wang Qiaoqiao stood alone, fighting an isolated battle.

Zhou Kai sat at the bow, his Divine Sense capturing every whisper and sigh from the cabin. He smirked.

Just a few people, and it’s already this lively.

One was gentle and magnanimous, one was a manipulative crybaby, one was sharp and aggressive… and Lin Zhiwei was the supposedly neutral party who had already picked a side.

If he added more beauties in the future, the covert struggles would rival an imperial harem.

“The path of immortal cultivation is long,” Zhou Kai mused. “Without these worldly adornments, wouldn’t it be too dull?”

He viewed it as scenery on his journey. As long as they didn’t cross his bottom line or damage the team’s fundamental harmony, he enjoyed the heat. A little competition spurred ambition.

“Zhou Lang.”

Wang Qiaoqiao’s soft voice drifted from the cabin. She walked onto the deck, her hips swaying, and sat beside him. She rested her head on his shoulder, her voice dropping to a whisper.

“Zhou Lang, when we reach Calamity Abyss Valley, can we find a larger cave dwelling? Or perhaps… set aside a separate quiet room for me? I don’t want to live too close to them. I want to avoid the constant friction.”

Zhou Kai wrapped an arm around her slender waist, pulling her flush against him. He whispered warmly into her ear, “Oh? Living with them has made you feel wronged?”

Wang Qiaoqiao huffed lightly. “That Chen Ziqing is an expert at insinuations, and Lin Zhiwei defends them blindly. The air in there is stifling. It would be better if we had our own space—out of sight, out of mind.”

Zhou Kai pondered for a moment. “I understand. There’s no rush. We’ll assess the terrain at Calamity Abyss Valley first. Don’t worry, I won’t let you be wronged.”

Seeing he wasn’t dismissive, Wang Qiaoqiao relaxed, leaning into his touch.

Suddenly, Zhou Kai’s expression shifted. His Divine Sense snapped into focus.

Below the sea of clouds, within the vast mountain range, violent ripples of spiritual energy were flaring. Intense combat was underway.

“Zhou Lang, are people fighting down there?” Wang Qiaoqiao noticed his change in demeanor.

Zhou Kai withdrew his senses, his face indifferent. “Just some late-stage Qi Condensation cultivators killing each other. It has nothing to do with us. We’ll fly past.”

Curious, Wang Qiaoqiao strained her eyes, peering through the clouds.

“Huh?”

She squinted at the flashes of light below. “Zhou Lang! Look quickly! That sword-wielder… why does she look familiar?”

A wanted poster flashed through her mind, aligning with the figure below.

“Wait… white robes, sword light… could that be the Sword Fairy of Lone Goose Palace… Shen Hanyi?”

Shen Hanyi?

Zhou Kai’s gaze shot downward instantly.

Indeed! That aloof, untouchable figure. The golden-white sword lights tearing through the gloom. The chilling, palpable killing intent. It was Shen Hanyi!

She was being besieged by six cultivators in matching uniforms. She looked disheveled, her movements slightly ragged.

Six against one?

Zhou Kai’s Divine Sense swept the battlefield. No, five were attacking. The sixth lay nearby with a gruesome, bloody hole punched through his chest—Shen Hanyi’s handiwork.

Fighting one against six and killing one first? Truly worthy of a born Sword Embryo.

But she was running on fumes. Her spiritual energy was depleted, and her sword momentum was faltering.

The five attackers were nasty pieces of work. Some commanded desiccated corpses exuding thick death energy; others unleashed pitch-black talismans that screamed with ghostly wails.

Demonic cultivators.

“Holy shit!” Zhou Kai cursed inwardly. That’s my future wife!

Without a second thought, his figure blurred, shooting like a bolt of lightning toward the forest below.

“Han Yi! I’m here to help!”

His roar rolled like thunder, the sheer sonic pressure dispersing the incoming spell attacks from the demonic cultivators.

These trash were at most Qi Condensation ninth layer. How could they withstand him?

Zhou Kai descended like a meteor. His Wandering Dragon White Jade Body activated, his skin glowing with a faint luster as his massive Vitality surged.

He didn’t use a weapon. He didn’t need one.

“Bang!” “Bang!” “Bang!”

Qi Condensation cultivators were fragile as wet paper before a Bone Forging stage body cultivator.

The first target, a cultivator controlling a corpse puppet, didn’t even have time to scream. Zhou Kai’s fist connected with his skull.

SPLAT.

The man’s head exploded like a watermelon dropped from a tower. His headless body collapsed like a ragged sack.

The second enemy, activating a ghost-wail talisman, tried to sidestep. Zhou Kai didn’t stop; he drove a vicious elbow into the man’s chest.

CRACK-CRUNCH.

The sound of the sternum shattering was sickeningly loud. The man’s chest caved in completely, his heart pulped instantly. He spat a fountain of blood and collapsed, life extinguished.

The remaining three froze in absolute terror.

“Run!” one screamed.

They scattered, using strange movement techniques to flee in three different directions.

“Want to leave? Too late!”

Zhou Kai snorted coldly. He moved like a phantom, his shadow stretching and snapping as he pursued them.

One punch. One kick. One chop.

It was a massacre. Swift as a falcon snatching rabbits, he hunted them down one by one within mere breaths.

Silence returned to the forest.

Zhou Kai stood amidst the carnage, shaking the blood off his hands. He turned to look at Shen Hanyi.

Her white robes were stained with blood, her usually neat hair bun slightly messy, but she stood upright, her sword held steady. Her clear, cold eyes held a trace of surprise… and complexity.

“It’s you…” Shen Hanyi spoke softly.

She opened her mouth to address him as “Fellow Daoist Zhou,” but her Divine Sense caught the terrifying ocean of Vitality rolling beneath his skin.

Bone Forging stage?!

“Senior… Zhou…” She corrected herself instantly.

Zhou Kai walked up to her, scanning her body. Aside from fatigue and some superficial cuts, she was fine. He let out a breath of relief.

“Is your Sword Embryo injury healed?” he asked, referring to the damage she took back at Crouching Tiger Mountain.

Shen Hanyi met his gaze. “Healed.”

“How did this conflict start?”

Shen Hanyi was characteristically brief. “I was traveling. I saw Yin Ruins Sect demonic cultivators. I should kill them.”

Zhou Kai’s mouth twitched.

Truly, a sword cultivator’s brain circuit is uniquely clear.

The Yin Ruins Sect was one of the eleven great sects of the East Region. These disciples weren’t weak. Yet she saw them and thought, “Demonic? Kill,” without weighing the pros and cons or her own odds.

Zhou Kai chuckled, reaching out to pat her shoulder firmly. “Alright, fine. As long as you’re happy.”

Shen Hanyi stiffened slightly at the contact but didn’t pull away.

Zhou Kai withdrew his hand, his gaze locking with her cold eyes. His voice turned serious.

“Hanyi. You promised me. Before ‘that’ happens… you cannot die.”

Shen Hanyi’s eyes flickered. She pursed her lips. “I won’t die.”

Zhou Kai stared at her. Was that a promise, or just her stating a fact? With sword cultivators, it was hard to tell.

Just then, wind pressure descended from above. The Spirit Boat landed steadily in the clearing.

Four figures filed out. Chen Ziyi, Chen Ziqing, Wang Qiaoqiao, and Lin Zhiwei.

They immediately saw the scene: Zhou Kai standing opposite a white-robed woman of transcendent, icy beauty, surrounded by six brutalized corpses. The air was thick with the scent of blood and lingering demonic energy.

The four women’s gazes locked onto Shen Hanyi instantly, filled with curiosity and scrutiny.

Lin Zhiwei, who had never seen the Sword Fairy, looked confused. “Senior Zhou… who is this?”

Shen Hanyi’s gaze swept over the four women. She seemed to ponder for a moment on how to answer.

Under Zhou Kai’s expectant gaze, Shen Hanyi pursed her lips. Her voice was clear, cold, calm, and carried an astonishing bluntness.

“I am Senior Zhou Kai’s Cultivation Vessel.”
