He hit level 35 on the fourth day, as Herald had predicted.
The final fifteen levels came from a combination of Class A dungeon runs and extended Portal sessions in the First Layer, where the ambient mana absorption kept his Void Core in a constant state of active processing. The level gains in the Underworld came faster than anywhere else. The mythological mana was richer, denser, more compatible with his Void-type affinity than the surface world's ambient field.
Shadow 300 was a Norse Shade Specter extracted from the deepest point of the First Layer that his Portal could currently access. It was a C-rank-plus entity that had been solitary in the dark forest for what felt, from its shadow, like centuries. When it entered the Register and settled beside the Einherjar patrol, there was a moment of recognition between them that Liu Yun felt as a faint warmth in the Void Core. Old comrades, perhaps, from a mythology that had made companionship in death as significant as companionship in life.
The Major Quest completed the moment Shadow-300 was registered:
[MAJOR QUEST COMPLETE: VOID SOVEREIGN'S DECREE][ABILITY UPGRADED: SHADOW DOMAIN (ADVANCED). Range increased to 200 meters. Effect: Shadow soldiers within Domain gain +50% to all combat stats. Enemy creatures within Domain are suppressed. Suppressed creatures suffer 30% reduction in speed, strength, and ability activation.

All shadow soldiers gain +10% permanent stat increase. Passive effect: enemies with information-type abilities who observe the host experience involuntary threat-response. The title generates a natural aura of authority recognizable to Underworld entities.]
He read the title description twice.
Enemies with information-type abilities experience involuntary threat-response. He thought of Director Voss in Conference Room 7, and the expression on his face that had stopped pretending to be pleasant. He thought of Sera's ice-sense lighting up the first time she had walked into the warehouse.
They had both felt it. His title had been almost there even then.
Sera was waiting in the training space when he returned. She looked at him as he came through the door and her expression went through three distinct phases in the space of a second: first assessment, then surprise, then something that settled into a kind of careful recognition.
"Something changed," she said.
"The title." He told her about the Shadow Sovereign designation and the ability upgrades. She listened without interrupting.
When he finished she was quiet for a moment.
"The Shadow Domain," she said. "Two hundred meter radius. Can you overlap it with my ice-sense field?"
"We would have to test it. But theoretically the void-suppression and your temperature drop would stack."
She nodded slowly. "Combined, that is close to an S-rank force multiplier." She looked at him steadily. "You are ready for Sector 2."
"Almost," he said. "I want one more Portal run first. There is something in the First Layer I want to retrieve."
She raised an eyebrow.
"The Oracle mentioned something last time I spoke with her," he said. "In the First Layer, approximately four kilometers from my standard entry point, there is a sealed vault similar to the hidden chamber where I found the Void Chronicle. It is older than the dungeon network. It contains a Mythological-Class shadow soldier that was placed there by the first Void Sovereign."
"The one who built the system."
"Yes. The original user." He had been thinking about this since the Oracle mentioned it. The first Void Sovereign had lived before the Gates existed, in a time when the Underworld pressed against the mortal world through different means. They had built the Chronicle, created the shadow extraction methodology, fought Bael's predecessor, and when they died, they had left something behind. A general. The greatest shadow in the original army, sealed in the First Layer to wait for the next inheritor of the Void.
"How long has it been waiting?" Sera asked.
"The Oracle said approximately four thousand years."
Sera was quiet.
"Four thousand years," she repeated.
"I will bring it back before we hit Sector 2," he said.
He went north the next morning at dawn, Portal entry at the standard point, moving east-northeast through the silver-barked forest at a pace that the shadow soldiers around him matched without effort. Six hours of travel in the First Layer, time moved differently there, compressed in a way that made the Underworld's distances shorter than a surface map would suggest, brought him to a place where the forest ended abruptly.
Not thinned. Ended. The silver-bark trees simply stopped at a boundary as exact as a wall, their trunks leaning slightly away from what lay beyond, and what lay beyond was a space that the First Layer's creature population had very clearly decided to leave alone.
A vault of black stone, unmarked, the size of a small house. Its door was sealed with void-substance, the same material as the Void Chronicle's cover, in a lock that opened the moment Liu Yun pressed his palm against it. Not because he had a key. Because he was the key. The Void Sovereign's bloodline, the Chronicle's chosen host, the inheritor.
Inside, one pillar. One chain. One shadow that was darker than the absence of light and that had the shape of a general.
He reached for it.
It reached back.
[LEGENDARY SHADOW EXTRACTED: THE FIRST GENERAL. UNIT DESIGNATION: NYX][Classification: Beyond System Measurement][Note: This unit is the supreme shadow of the original Void Sovereign's army. Its loyalty is absolute. Its power is immeasurable by current metrics. It is not a soldier. It is a Commander.]
The vault's walls dissolved around him as Nyx rose from his shadow. Not the shape of any creature he recognized, but the shape of something that was itself: pure void-substance, humanoid in outline, precise in its stillness, its non-face turned toward him with an attention so complete it felt like pressure.
It bowed.
After four thousand years of waiting, it simply bowed.
Liu Yun stood in the empty First Layer clearing where the vault had been, looked at Nyx, and felt, for the first time, the full weight of what the Void Chronicle had chosen him for.
He stood up straight and bore the weight.
"Come," he said. "We have work to do."
