Floor nine hit different.
The air tasted like ozone and ash. Lightning crackled across obsidian walls. Shadow beasts prowled through electric fields like they owned the place.
Jayden's eye pulsed the moment they stepped through.
**[SHADOW + LIGHTNING ESSENCE CONCENTRATION: EXTREME]**
**[AFFINITY MATCH DETECTED x2]**
**[GROWTH POTENTIAL: MAXIMUM]**
His heart hammered. Both his affinities. In one place.
"This floor was made for you," Elena said.
"Yeah." He couldn't hide the hunger in his voice. "It really was."
The first beast charged. Shadow wolf wrapped in electric fury. C rank. Fast.
Jayden moved faster.
Shadow Step behind it. Blade through the spine. Lightning discharged into the wound.
The beast dissolved into essence.
It flowed into him like water finding cracks. Hot. Electric. Perfect.
**[DUAL AFFINITY ABSORPTION]**
**[EFFICIENCY: 680%]**
**[GROWTH ACCELERATING…]**
His body lit up. Black and purple. Shadow and lightning merging under his skin.
"Keep moving," he said. Voice rough. "I need more."
They pushed deeper. Found a nest. Twenty beasts. All shadow lightning hybrids.
Marcus grinned. "All yours, captain."
"Cover me if I lose control."
"If?"
Jayden didn't answer. He was already moving.
Shadow Step. Strike. Step. Strike.
His blade became a blur. Each kill fed him more essence. Each absorption made him faster.
The beasts adapted. Attacked in groups. Coordinated.
Didn't matter.
Jayden's eye tracked them all. Combat Prediction v2.0 showing twelve futures simultaneously. He picked the path where he won everything.
His speed climbed. 25.4 to 26.1. Then 26.8.
Still rising.
The final beast lunged. Jayden caught it mid air. Stabbed through its core. Held it as essence flooded him.
Something inside him cracked.
Not broke. Evolved.
His shadow and lightning affinities collided. Merged. Fused.
Black lightning erupted from his body.
Not purple. Not white. Pure black with crimson edges.
The team stumbled back.
"What the hell?" Marcus shielded his eyes.
Jayden looked at his hands. Black lightning danced between his fingers. Solid. Controllable. Powerful.
**[NEW ABILITY UNLOCKED: BLACK LIGHTNING]**

**[PROPERTIES:]**

"Holy shit." Zain stepped closer. "Is that "
"A fusion affinity." Elena's voice was stunned. "I've read about these. They're supposed to be mythical."
"They're real." Jayden shaped the black lightning into a sphere. It crackled with barely contained violence. "And it's mine."
He threw it at a distant wall.
The impact cratered stone. Black scorch marks spreading like infection.
"That's stronger than both your affinities combined," Cinna said.
"Yeah." Jayden felt it growing already. Learning. Adapting. "And it'll get stronger. The description says it grows with me."
His eye pulsed. New data flooding in.
**[BLACK LIGHTNING GROWTH PATH DETECTED]**
**[TIER 1: Basic manifestation]**
**[TIER 2: Weapon infusion (LOCKED Requires 10 uses)]**
**[TIER 3: Area attacks (LOCKED Requires 50 uses)]**
**[TIER 4: ??? (LOCKED)]**
A skill tree. Built into his body.
"We need to test this," Jayden said. "Find stronger enemies."
"Floor ten has them," Vance's voice came from behind.
They spun. She stood at the entrance, arms crossed.
"You're early," Elena said.
"I felt the essence spike. Came to investigate." Vance's eyes locked on Jayden's hands. Still crackling with black lightning. "A fusion affinity. At fifteen. Unheard of."
"Is it dangerous?"
"Extremely. To your enemies." She approached carefully. "May I?"
Jayden nodded. She reached out, essence probing the black lightning.
Her expression shifted. Surprise. Then concern.
"This isn't just fusion. It's evolution." She pulled back. "Your affinities didn't merge. They created something new. Something that will keep growing as long as you do."
"That's good, right?"
"If you can control it." Vance's tone darkened. "Fusion affinities have destroyed users who couldn't handle the power. The energy feedback alone should've killed you when it formed."
"But it didn't."
"Because of your broken limiter. Your body adapted in real time." She looked at the others. "He's officially beyond normal classification now. This ability alone puts him in a category above standard rankings."
Marcus cracked his knuckles. "So he's special. We knew that. What's floor ten got?"
"Shadow lightning elementals. B rank minimum. Perfect for testing his new toy." Vance gestured upward. "But be warned. Elementals are intelligent. They'll adapt to his tactics."
"Good." Jayden's eye blazed. "I need the challenge."
They ascended.
Floor ten was a wasteland. Cracked earth. Lightning storms frozen mid strike. Shadow pools that moved like living things.
And in the center elementals.
Humanoid shapes made of pure essence. No flesh. No blood. Just power given form.
**[SHADOW LIGHTNING ELEMENTAL]**
**[RANK: B]**
**[SPEED: 22.7 units. POWER: 28.3 units]**
**[WARNING: HIGH RESISTANCE TO STANDARD ATTACKS]**
Five of them. All watching.
Jayden stepped forward. Black lightning already forming.
"Let me handle this."
"Alone?" Cinna asked.
"Trust me."
He walked into the center. The elementals circled. Sizing him up.
The first one attacked. Lightning spear. Fast.
Jayden's eye caught it. He raised his hand.
Black lightning erupted. Met the spear mid flight.
The two forces collided. The elemental's attack shattered. Absorbed.
**[BLACK LIGHTNING ABSORPTION CAPABILITY DETECTED]**
**[CAN CONSUME MATCHING ESSENCE TYPES]**
Perfect.
Jayden smiled. "My turn."
He moved. Shadow Step. Black lightning trailing like wings.
The elemental tried to dodge. Too slow.
Jayden's blade, wrapped in black lightning, pierced its core.
The elemental screamed. Not sound. Pure essence distortion.
It exploded into fragments. All of it flowing into Jayden.
**[MASSIVE ABSORPTION DUAL AFFINITY MATCH]**
**[GROWTH ACCELERATING]**
**[BLACK LIGHTNING: TIER 1 PROGRESS 12%]**
Four elementals left. They attacked together.
Smart. Coordinated. Dangerous.
Jayden's eye showed him the future. Every attack path. Every opening.
He moved through them like smoke.
Shadow Step. Strike. Black lightning discharge.
Shadow Step. Strike. Absorb the counterattack.
His new ability was learning. Every use made it sharper. Faster. More efficient.
Third elemental fell. Then fourth.
The last one tried to run.
Jayden threw black lightning like a spear. It pierced straight through. The elemental dissolved.
Silence.
**[SPEED: 26.8 → 28.9 units]**
**[ATTACK POWER: 22.7 → 27.4 units]**
**[BLACK LIGHTNING: TIER 1 PROGRESS 47%]**
He was climbing faster than ever.
The team caught up. Staring at the destruction.
"Five B ranks," Zain said slowly. "In under three minutes."
"The fusion affinity is broken," Elena added. "It's not just stronger. It's made for killing essence beings."
Jayden felt it. The black lightning humming under his skin. Hungry. Growing.
"We clear the rest of this floor," he said. "All of it. I need to hit tier two before we leave."
"There's at least twenty more elementals," Vance warned.
"Good."
They spent the next six hours hunting.
Every elemental fell. Every death fed Jayden more power.
His black lightning evolved with each fight. Learning to arc. To chain between targets. To explode on impact.
By the time they cleared the floor, he was different.
Faster. Stronger. More refined.
**[SPEED: 28.9 → 31.2 units]**
**[ATTACK POWER: 27.4 → 32.8 units]**
**[BLACK LIGHTNING: TIER 2 UNLOCKED]**
**[NEW ABILITY: WEAPON INFUSION]**
**[CAN NOW PERMANENTLY ENHANCE WEAPONS WITH BLACK LIGHTNING]**
Jayden looked at his blade. Shadow steel. His father's gift.
He channeled black lightning into it.
The metal drank it. Absorbed it. Changed.
The blade turned midnight black. Lightning etched into every inch. Alive.
**[SHADOW BLADE EVOLUTION]**
**[RANK: C → B]**
**[NEW PROPERTY: BLACK LIGHTNING EDGE IGNORES 40% OF ENEMY DEFENSE]**
"That's a Master tier weapon now," Vance said. Voice quiet. Awed. "In six hours, you jumped from Grandmaster to damn near Sage level metrics."
"Not Sage yet." Jayden sheathed the blade. "But close."
Marcus collapsed against a wall. "Dude. You're a monster."
"Yeah." Jayden didn't deny it. "That's the point."
They rested. Ate. Recovered.
Cinna approached Jayden during the quiet. "You okay? That much essence absorption can mess with your head."
"I'm fine." He looked at his hands. Black lightning sparking faintly. "Just… hungry."
"For what?"
"More." His eye flickered crimson. "Always more."
She didn't push. Just sat beside him.
"We're getting stronger," she said. "All of us. At this rate, we might actually survive what's coming."
"Survive's not enough." Jayden's voice was steel. "I want to win."
"Against Theron?"
"Against everyone." He stood. "Five more floors. Then we go back. Clear our names. End this."
Cinna stood with him. "You really think we can?"
Jayden's eye pulsed. Calculated probabilities. Futures. Outcomes.
**[VICTORY PROBABILITY: 67%]**
**[WITH BLACK LIGHTNING TIER 3: 78%]**
**[WITH BLACK LIGHTNING TIER 4: 89%]**
"Yeah." He smiled. Sharp. Dangerous. "I really think we can."
That night, they slept in shifts.
Jayden took last watch. Sat at the floor entrance. Black lightning dancing between his fingers.
He shaped it. Molded it. Learned its language.
**[BLACK LIGHTNING TIER 2 PROGRESS: 23%]**
Growing. Always growing.
His eye flickered. Showed him a vision.
Him standing before Theron. Black lightning in one hand. Shadow blade in the other.
The Headmaster's face twisted in fear.
Then the vision faded.
Jayden stood. Stretched. Felt power coiling in every muscle.
Five floors left.
One week until the kingdom closed in.
And a fusion affinity that made him unstoppable.
Time to finish what they started.
His black lightning flared once.
Then he stepped into the darkness.
