The sky above Skyforge City burned wrong. Lin Dong noticed it the moment he stepped onto the upper terrace reserved for inter-realm envoys. The divine flames that usually flowed in orderly currents now flickered with subtle dissonance—colors bending where they shouldn’t, heat folding inward instead of radiating out. To most, it would appear as nothing more than atmospheric instability, a side effect of recent trials. To Lin Dong, it felt like a heartbeat skipping. Arius hovered closer than usual, his flame dim but alert, pulsing in uneven rhythms. They’re watching again, the spirit whispered. More carefully this time. Lin Dong didn’t respond aloud. His Nine Flames rotated in disciplined harmony beneath his skin, suppressing their instinct to flare. Since the confrontation with the Celestial Order and the revelation of Arius’ origin, the Frontier itself felt less like a realm and more like a cage crafted of law and expectation. And cages, Lin Dong knew, always attracted wardens.

The invitation did not come in words. It came as heat. Not the violent, devouring kind that roared when gods clashed or realms burned—but a low, persistent warmth that threaded itself through Lin Dong’s forge flame like a half-forgotten memory. It pulsed once… twice… then settled into a steady rhythm, guiding rather than commanding. Arius felt it first. This flame… the spirit whispered, his glow flickering with unease and awe. It’s old. Older than Heaven’s Laws. Lin Dong opened his eyes. He stood alone on the highest terrace of the Phoenix Clan enclave, Skyforge City spread beneath him like a constellation of living embers. The Celestial Frontier shimmered under layered divine arrays, yet beyond them—far beyond—he sensed something buried, sealed, and deliberately forgotten. “The Smoldering Vault,” he murmured. The name surfaced unbidden, carried by ancestral memory rather than knowledge. Behind him, the air rippled. Matriarch Feng Hualin stepped into view, her expression gr

Skyforge City never truly slept. Even in the deepest hours of the celestial cycle—when the divine suns dimmed to embers and the floating continents drifted in slow, deliberate orbits—the city hummed. Flame veins beneath the streets pulsed with restrained power, carrying heat, law, and will through structures older than most gods remembered. Lin Dong felt it the moment he crossed the threshold into the lower sanctums. This was not the Skyforge the Celestial Order displayed to visitors. This was its heart. The descent began beneath the Phoenix Clan’s outer district, through an aperture that only revealed itself when Lin Dong pressed his palm to a seemingly solid obsidian wall. The Nine Flames within him responded instinctively, releasing a controlled resonance. The wall rippled, folded inward like liquid metal, and revealed a spiraling stair of dark-gold stone descending into silence. Arius hovered closer than usual, his flame dim but alert. This place… it remembers, he whispere

Silence returned to the depths of Skyforge—but it was no longer empty. It pressed in from every direction, thick and watchful, like a presence holding its breath. The ancient cavern still bore the scars of the battle: fractured stone, frozen rivulets of corrupted flame hardened into jagged obsidian, and at the center of it all, a single ember pulsing faintly on the forge floor. The remnant of the cursed flame. Lin Dong stood before it, unmoving. The ember was no larger than a grain of rice, black at its core and rimmed with a dim, bruised violet glow. It looked fragile—harmless, even. Yet Lin Dong could feel it, tugging subtly at the Nine Flames within him, not with force, but with familiarity. Like an old scar aching before a storm. Arius hovered weakly at Lin Dong’s side, his once-brilliant form now subdued, streaked with faint lines of darkness that pulsed in slow rhythm. Though he had stabilized, the corruption he absorbed had not vanished—it slept. “This ember…” Arius murm

The air still trembled from the cataclysm within the Forbidden Crucible. Molten soul-rivers of the fallen forge evaporated into sparks of pure law, drifting like fireflies across the fractured sky of the Celestial Frontier. The echo of the Crucible Warden’s voice—silent now, but lingering like a wound in space—resonated through Lin Dong’s body. Every step he took was heavy; his mortal form had survived, but its divine core still carried the scars of forbidden flames. Arius hovered close, his glow faint and erratic, a reflection of the damage he had endured absorbing the crucible’s corruption. The young flame’s whisper was almost a moan. “Lin Dong… the crucible… it knows your essence now. It will mark you.” Lin Dong tightened his grip on his staff, his core simmering with raw, unstable power. “I know,” he said quietly. “And yet… I survived. That means there’s still a path forward.” The fragmented sky above the forge pulsed faintly. Then, like a beacon in the void, a radiant flame d
