The amber light of Elara's staff didn't just illuminate the Silt District; it felt like an interrogation. Atsu Yuta stood perfectly still, his apathetic gaze fixed on the glowing crystal. He could feel the blood he had just absorbed the thief's blood sloshing in his internal system. It was raw, unrefined, and chaotic.
His mind began to work, his "数字" tattoo feeling like a warm brand against his skin. This was the calculation phase. He had no energy for another fight, yet here was an Imperial Academy prodigy standing in his way.
"The Guild says the 'Cursed Blood' is a void," Elara said, taking a step closer. She didn't hold her staff like a weapon, but like a lantern. "They say you destroy mana. But I just saw you take something. You didn't destroy that man's life force; you... integrated it."
"You should leave," Atsu said, his voice a flat line. "Being near me isn't safe for someone who relies on wands."
"I noticed," she replied with a small, sharp smile. She pointed to the amber crystal. It was pulsing irregularly, the light dimming and brightening in a rhythm that matched Atsu's own heavy pulse. "You're not just a sinkhole, Yuta. You're a transformer. You're changing the local laws of physics."
Atsu felt a sharp spike of heat in his chest. The raw blood he had taken was starting to burn. It was too much material for his body to hold as mere liquid. If he didn't use it, his veins would rupture from the internal pressure.
System Alert: Material Overflow. Select Conversion Mode.
The choice appeared in his mind as a cold, logical fork in a road.
Option 1: Material Source (Creation). He could vent the blood now, turning it into another wall or a weapon. But there was no one to fight, and the "Type 2" monitors would see the red mist from blocks away.
Option 2: Mana Reserve (Energy). He could break the blood down, stripping it of its physical form and storing the essence as internal fuel.
Atsu closed his eyes. He chose Option 2.
The sensation was agonizing. It felt like his veins were being filled with molten lead that suddenly evaporated into steam. Internally, the liquid blood he had drawn from the thief was being crushed by his own anomalous logic, converted into a high-density energy source. The dark, bruised purple of his veins faded, replaced by a faint, steady glow beneath his skin that only a mage could see.
The fatigue that had been crushing his lungs vanished. His vision sharpened. The "Mana Reserve" was now active, providing him with a stable foundation for prolonged survival.
Elara's eyes widened as she watched the glow settle beneath his skin. "You just... ate it. You converted physical matter into a mana-equivalent without a circle or a catalyst."
"It's not mana," Atsu corrected, his voice regaining its detached strength. "It's just a battery. And it's running on a dead man's time."
He turned to walk away, but Elara followed him, her boots clicking rhythmically against the damp cobblestones. "The Academy has a secret vault, Yuta. They have records of 'System Breakers' from before the Seven Elements were codified. The Guild erased them, but my family kept copies. They call people like you 'The Living Human Break.'"
Atsu stopped. The name the hooded figure had used. "Why are you telling me this?"
Atsu stopped. The name the hooded figure had used. "Why are you telling me this?"
"Because the Guild isn't trying to 'contain' you," she whispered, leaning in so the light of her staff was the only thing between them. "They're trying to trigger you. They want to see how much you can disrupt before you break. You're not a prisoner to them you're an experiment."
Atsu looked at her. For the first time, his apathetic expression wavered. A "False Ally" interruption. Was she a researcher looking for a specimen, or a rebel looking for a weapon? His mind began to run the probabilities.
"If I'm an experiment," Atsu said, his fingers twitching near the cross tattoo on his hand, "then you're a witness. And witnesses usually get removed from the equation."
"I'm a variable you can't account for yet," she countered. She reached into her pocket and pulled out a small, silver coin etched with a number: 0. "Take this. It's a localized dampener. It will hide your 'leak' from the Guild's sensors for a few hours. Meet me at the Iron Market tomorrow at midnight if you want to know what the numbers on your face actually mean."
She tossed the coin. Atsu caught it instinctively. The moment his fingers touched the silver, the static in the air around him died down. The hum of the amber crystal stabilized.
Elara didn't wait for an answer. She turned and vanished into the fog of the Silt District, leaving Atsu alone with the taste of iron in his mouth and a reservoir of stolen energy in his chest.
He looked down at the coin. He could feel the Guild's presence in the distance the far-off chime of pursuit bells. He had a choice. He could disappear into the shadows and live as a stray, or he could step into the light of a girl who seemed to know his own system better than he did.
He tucked the coin into his pocket and placed the unlit cigarette back behind his ear.
"Calculation," he whispered to the darkness. "Midnight."
