I approached the convergence point of the four valleys first, the Primordial Wellspring cradled carefully in my spiritual hands. The area seemed to respond to the water's presence even before I placed it, the ground subtly reshaping itself to create a perfect receptacle.

"Here goes," I murmured, setting the water cube at the exact center of the convergence.

The reaction was immediate and dramatic. The perfect cube began to dissolve, spreading outward in four distinct streams that followed the valleys radiating from the center. Wherever the water touched, the ground responded: stones smoothed, soil enriched, and subtle formations activated that helped guide the water's flow.

Within minutes, the beginnings of a proper water system had formed throughout my inner world. Small pools collected in natural depressions, streams wound their way through the landscape, and a modest lake began forming in the garden quadrant. I could feel the water establishing its own form of order, a fundamental Water Law that would govern its behavior throughout my domain.

Next, I carried the Minor Spirit Vein to the cavity beneath the meditation plateau. As I approached, the rock face parted like curtains to reveal a chamber perfectly shaped to house the crystalline structure. I carefully positioned the Spirit Vein, aligning its main trunk with the vertical energy flow and its branches with the horizontal pathways that extended throughout my inner world.

Unlike the Wellspring's dramatic expansion, the Spirit Vein's integration was more subtle but no less profound. As it settled into place, thousands of tiny filaments extended from its crystalline structure, connecting with the existing spiritual pathways of my inner world. Almost immediately, I sensed an improvement in qi circulation, areas that had previously been spiritually "dry" now hummed with energy.

The Temporal Hourglass required the most precise positioning. I approached the Genesis Seed, studying its structure carefully before identifying the optimal placement. The seed seemed to recognize my intent, several of its smaller branches shifting slightly to create a natural cradle at exactly the right height and orientation.

I placed the hourglass in this living cradle, ensuring its axis of rotation aligned perfectly with the seed's growth direction. The moment it settled into place, a ripple of distortion spread outward, not visible to the eye but perceptible to my spiritual sense as a subtle stretching of time itself.

"The effect is establishing properly," Azure confirmed. "It's currently calibrating to your inner world's natural rhythm. Once stabilized, you'll experience a perfect two-to-one time ratio without any distortion or side effects."

Finally, I approached one of the small ponds that had formed in the garden quadrant, the crystal vial containing the Dawn Ripple in hand. Kneeling at the water's edge, I uncorked the vial and gently tipped it, allowing the tiny fish to swim into its new home.

For a moment, nothing happened as the Dawn Ripple remained motionless, perhaps adjusting to the sudden change in environment. Then, with a flick of its translucent tail, it darted forward, leaving a barely perceptible trail of spiritual essence behind it.

"It likes the water," I observed with a smile.

Yggy, who had been watching the entire process with rapt attention, extended a tendril toward the pond's surface. The vine hovered just above the water, as if hesitant to disturb the Dawn Ripple's exploration.

"You can touch the water," I told Yggy. "Just be gentle."

Yggy's tendril dipped cautiously into the pond, creating ripples that spread outward. The Dawn Ripple, rather than fleeing, swam toward the disturbance with apparent curiosity. To my surprise, it circled Yggy's tendril twice before nudging it gently.

"I think it's greeting you," I chuckled.

Yggy's entire form wiggled with what I could only interpret as delight.

"Master, would you look at that," Azure said with amusement in his voice. "Not even five minutes together and they're already friends. Funny how beings from completely different worlds can connect so easily while cultivators spend centuries bickering over the slightest differences in their perception of the Dao."

I smiled, watching them interact. "Maybe there's a lesson in that. We cultivators overthink everything, analyzing motives, calculating advantages. These two just... accept each other." I shook my head slightly.

As I stepped back to observe all four treasures functioning in harmony, something exciting began to happen. The Genesis Seed at the center pulsed with energy, its roots visibly extending further into the ground. A gentle pressure started spreading through my inner world, like the feeling of a muscle stretched to its limit before growing stronger.

"Azure," I said, my voice hushed with realization, "I think it's happening."

Azure's form brightened perceptibly. "Indeed, Master. The integration of these treasures has provided the final components needed for your breakthrough to the Ninth Stage of Qi Condensation."

The pressure increased, not painful but impossible to ignore. The expansion came in waves, each one pushing the boundaries of my inner world further outward. With each wave, I felt my connection to the World Tree Sutra deepen, my understanding of its principles growing clearer.

I moved toward the Genesis Seed, settling into a meditative position before it and synchronizing my breathing with the pulsing waves of expansion. Closing my eyes, I extended my spiritual sense throughout my inner world, feeling for any areas of resistance or imbalance. The four quadrants, mountain, garden, structure, and practice, all needed to expand harmoniously to maintain the world's stability.

As I directed my awareness through each section, memories of my cultivation journey flickered through my mind. The confusion upon first awakening in Ke Yin's body. The discovery of the World Tree Sutra. My first visit to the Two Sun’s World. My first tentative steps in formation study. The gradual building of relationships with Wei Lin, Lin Mei, and even Elder Chen Yong. Each memory seemed to fuel the expansion, as if my experiences were as vital to my cultivation as qi itself.

Opening my eyes, I found the Genesis Seed itself was transforming, its trunk thickening, branches reaching higher toward the suns while its roots delved deeper into the foundation of my inner world. The air around it shimmered with concentrated spiritual energy, creating a vortex that drew in ambient qi and released it refined and strengthened.

A surge of power suddenly rushed through me, filling every meridian with vibrant energy. The boundaries of my inner world expanded in one final, dramatic push, doubling in size. The sensation was exhilarating, like breaking through a barrier I hadn't fully realized was constraining me.

As the expansion stabilized, new awareness flooded my consciousness. My spiritual perception extended further beyond my physical form. My understanding of the World Tree Sutra deepened, revealing nuances in its principles I hadn't previously grasped. Most tangibly, I felt the capacity of my essence reserves double.

"Ninth stage of Qi Condensation," I breathed, opening my eyes to survey my transformed inner world. "It's... incredible."

"Congratulations, Master," Azure said, genuine pride in his voice. "Few cultivators achieve such a smooth breakthrough. Your foundation is remarkably stable."

Cultivation: Qi Condensation Stage 9

Inner World: Radius of 3200 meters

Soul Essence: 6500/6500

Spiritual Essence: 6000/6000

Physical Essence: 6000/6000

The numbers weren't just abstract values; I could feel the profound difference in my capacity. Where before my essence had felt like a deep well, now it was a vast lake, doubled in volume and significantly more stable. My inner world had expanded far beyond the typical range for early ninth stage cultivators, likely due to the World Tree Sutra's Beyond Heaven classification.

But more than the raw numbers, I sensed qualitative improvements as well. My spiritual perception reached further, my connection to the natural world felt more intimate, and the energy flowing through my meridians responded to my will with greater precision and less resistance.

I spent some time examining the other changes throughout my inner world. The Primordial Wellspring had responded to the expansion by increasing its output, the flow of water from the source becoming stronger to accommodate the larger area it needed to irrigate. New streams were already forming, branching out toward the expanded boundaries.

The Minor Spirit Vein had similarly adjusted, its network of energy distribution extending farther in all directions. I could sense the subtle improvements in spiritual density throughout my inner world, the atmosphere itself becoming more conducive to cultivation and growth.

Even the Dawn Ripple seemed to be responding positively to the changes, swimming with increased vigor as it explored its expanding environment. It would eventually reproduce, creating more of its kind to further enhance the water system throughout my inner world.

I watched the interaction between Yggy and the fish with a sense of satisfaction. This was just the beginning, the first steps toward a truly vibrant, living inner world.

"I should return to the physical world," I said eventually. "I've been in meditation for quite some time, and Wei Lin and Lin Mei will wonder what's become of me."

Azure nodded. "Your physical body requires sustenance after such a significant breakthrough."

With a final glance at my transformed inner world, I withdrew my consciousness, feeling the familiar shift as my awareness returned to my physical form. I opened my eyes to find myself still seated in the privacy formation in my room at the inn, the jade vial that had contained Zhao Xun's blood now empty before me.

The formation lines I'd drawn had burned away, their purpose fulfilled. Standing, I stretched my limbs, noting how different my body felt now, stronger, more responsive.

A quick glance out the window revealed that the sun was setting. I'd been in meditation most of the day. My stomach growled insistently, reminding me that spiritual advancement did nothing to diminish physical needs.

After dismantling the privacy formation and tidying the room, I stepped outside, immediately sensing two familiar presences approaching the courtyard, Wei Lin and Lin Mei had returned from their trip into town.

"Ke Yin!" Lin Mei called, her expression brightening as she spotted me. She carried several small packages wrapped in brown paper, likely herbs or materials purchased in the mountain markets. "We were just wondering if you'd emerged from your meditation yet."

Wei Lin followed close behind, a smile playing at his lips. "Something feels different about you," he remarked, his eyes narrowing slightly as he studied me. "Wait... did you—"

"Breakthrough to the ninth stage?" I couldn't suppress my smile. "Yes, I did."
