The return to the surface was not the triumphant march Captain Grog had likely imagined in his younger days. Instead, it was a silent, tense procession. The twelve recruits who had entered the Slime Cave as terrified children now walked behind Bō Ken as if he were a ghost they were afraid to touch.
Ken felt the weight of their stares. In his mind, he was still trying to reconcile the sensation of the strike. It wasn't just the math of the Aether System—the +400\% damage multiplier—it was the feeling of his own soul splitting in two to accommodate the conflicting flows of water and lightning.

[NEW TITLE EARNED: SLAYER OF CORRUPTION]
As they stepped out of the shimmering Rift and back into the sunlight of the Vanguard Guild's courtyard, the air changed. The smells of blooming jasmine and damp earth were a sharp contrast to the metallic tang of the Slime Cave.
But the peace didn't last. Standing in the center of the courtyard was a group of men in polished, crimson-and-gold armor. They didn't belong here. These were the Imperial Arbiters, the elite enforcers of the Capital's Guild Council.
"Captain Grog," the lead Arbiter said, his voice like grinding stones. He didn't look at the giant; he looked at the cooling steam still rising from Ken's shoulders. "We detected a Rank-Shift. A Red-Rank signature in a Green-Rank zone. Explain."
Grog stepped forward, his broken claymore still gripped in his hand. "It was Mo Zan's corruption, Arbiter. The cave was infested. We... we barely made it out."
The Arbiter's eyes narrowed, landing squarely on Ken. "An F-Rank trainee? With singed hair and the scent of ozone? Move aside, Captain."
Ken felt a cold prickle at the back of his neck. This was the "Weight of the Name." In this world, a thirteen-year-old having the power to erase a Red-Rank boss wasn't a miracle—it was a threat to the established order.
The Inspection
The Arbiter held up a crystal monocle—an Appraisal Eye.
"Boy. State your name and your primary affinity," the official commanded.
Ken took a breath. He remembered the lessons of his past life: Never show your full hand when the opponent is holding the deck.
"Bō Ken," he said, his Japanese name sounding sharp and alien in the courtyard. "I am a Vanguard. My affinity is... Aqua."
The Arbiter looked through the monocle.
[APPRAISAL RESULT]
> Name: Bō Ken
> Class: Vanguard Trainee
> Affinity: Aqua (Lvl 1)
> Mana Purity: Low
The Arbiter scoffed, lowering the glass. "The boy is a fluke. The Slime King must have been unstable due to the corruption. It probably self-destructed when he splashed it with a bucket's worth of water."
The other Arbiters laughed, a dry, mocking sound. They turned their backs, satisfied that no "Glitch" existed in their perfect system. But Ken saw the screen they couldn't see.
[SYSTEM WARNING]
[CLOAKING ACTIVE: DUAL-STREAM HIDDEN FROM EXTERNAL APPRAISAL]
[CAUTION: MO ZAN IS WATCHING]
The Guild Master's Secret
Once the Arbiters had departed, Grog grabbed Ken by the collar—not with malice, but with a desperate kind of urgency. He dragged him toward the tallest, most dilapidated tower in the Guild complex.
At the top sat an old man, his back to the door. The room was filled with thousands of scrolls, many of them rotting.
"Master," Grog wheezed. "It happened. The boy... he didn't just survive. He conducted."
The old man turned. His eyes were milky white—he was blind—but he looked directly at Ken's chest, where the two mana circuits resided.
"Bō Ken," the Master whispered. "Do you know what your name means in the old tongue?"
"Adventure," Ken replied simply.
"It means a journey into the unknown," the Master corrected. "But in this world, it is a death sentence. Mo Zan was the first 'Glitch.' He was a man who learned to use two elements at once, just like you. But the power corrupted him. He became the Evil King because the System couldn't contain him."
Ken's heart hammered. "I'm not like him."
"Then prove it," the Master said, tossing a heavy, rusted key onto the table. "This is the key to the Vanguard Vault. Inside is the gear of the original heroes. If you want to defeat Mo Zan, you cannot fight like a mage. You must fight like a storm."
The Training of a Shadow
For the next three days, Ken didn't sleep. He spent every hour in the Vault, a subterranean level of the guild that even the Arbiters didn't know existed.
He ignored the heavy plate armor and the golden spears. Instead, he found what he was looking for in a dusty corner: a pair of Gauntlets of the Deep and a Vial of Liquid Lightning.
He sat in a seiza position, opening his System menu.
"Allocate 40 points to Agility," Ken whispered. "15 to Intelligence."
[STATS UPDATED]
**[AGILITY: 52] — Your movements leave afterimages. **
**[INTELLIGENCE: 28] — Mana efficiency increased. **
He began to train. He didn't practice spells; he practiced integration. He would summon a sphere of water in his left hand and, with a surgical precision that made his head ache, he would thread a single, needle-thin strand of electricity through it.
If he went too fast, the water would boil and explode. If he went too slow, the electricity would dissipate.
By the end of the second night, he had created his first original technique.
"Aqua-Blade: Static Edge," he muttered.
A blade of high-pressure water extended from his gauntlet, vibrating with a high-pitched hum. It didn't just cut; it cauterized and paralyzed. It was a weapon designed for one thing: killing kings.
The Shadow's Invitation
While Ken trained, the world outside was rotting. In the village of Oakhaven, the Rifts were no longer spawning slimes. They were spawning Hollows—grey, faceless soldiers carrying the banner of Mo Zan.
In the Dark Citadel, Mo Zan watched Ken through a pool of obsidian liquid. He saw the boy's progress, the way his Agility was climbing, the way he moved with the grace of a Japanese warrior.
"He is building a sword of storm," Mo Zan said, his voice echoing in the empty throne room. "Good. A sword must be sharp before it is broken."
Mo Zan reached into the pool and pulled out a handful of shadows. He molded them into the shape of a bird and whispered into its ear.
"Go. Tell the boy the first General is coming. Tell him that the General of Ash will burn the Vanguard Guild to the ground unless he comes to the Borderlands."
The shadow-bird took flight, disappearing into the gray sky.
Back in the Vault, Ken looked up. He felt a shiver of pure, cold mana. The "Adventure" was moving into its next phase. He wasn't just a Level 12 trainee anymore.
He was the target.
