## Chapter 25: Thunder Unleashed
The sword tip grazed Xiao An's ribs, a line of fire searing through his tunic and into his skin. The smell of ozone and his own singed cloth filled his nostrils. He didn't feel the pain, not yet. All he felt was the pressure in his chest, the electric hum in his meridians begging for release. Holding back the [Thundering Thunderbolt Sword] was like trying to swallow a storm.
This is it. No more hiding.
The young master, his face a mask of cold elegance, flicked his wrist for a finishing thrust. "Know your place, gutter rat."
Xiao An didn't answer with words. He answered with a breath—a sharp, inward pull that seemed to suck the light from the rainy courtyard. The energy he'd been desperately containing coalesced in his core, a miniature sun of crackling lightning.
He didn't execute a form. He didn't follow a sequence. He simply unleashed.
[Thundering Thunderbolt Sword] — First Flash!
His blade, a simple piece of forged iron, ceased to be metal. It became a conduit. A jagged fork of pale blue lightning erupted from the tip, not as a projectile, but as a violent extension of the sword itself. It wasn't clean. It wasn't refined. It was raw, untamed power, the furious backlash of a technique he'd comprehended in an instant but had never truly set free.
The air cracked. Not a boom, but a sharp, deafening snap that felt like a physical blow to the eardrums.
The young master's perfect thrust met the lightning. The elegant silver of his sword met chaotic blue.
For a fraction of a second, they held. Sparks, real and tangible, erupted in a shower of white-hot stars, hissing as they hit the wet stone. Then the shockwave hit.
It was invisible, but it had weight. It rolled out from the point of collision like a heated gale. The three surrounding disciples, who had been moving in for a cheap strike, were caught mid-step. Their robes flattened against their bodies. One stumbled back, his boots skidding on the slick cobbles. Another cried out, throwing an arm over his eyes as dust and rainwater were blasted upward.
The young master's eyes, previously pools of arrogant disdain, widened. The impact traveled up his arm, a jolt that numbed his fingers. He was forced back a single step, his heel grinding against the stone. A single step. But in that world, it was a chasm.
Xiao An pressed the advantage, the momentum of the release carrying him forward. His movements were nothing like the young master's fluid, practiced grace. They were brutal, efficient. He hacked, he slammed, his sword trailing fading arcs of sizzling energy. Each clash was a miniature detonation.
CLANG-SPZZT!
CLANG-CRACK!
The sound was all wrong. It was metal, but underneath it was the constant, angry fry of lightning.
"Impossible!" the young master spat, his composure cracking like his footing. His swordplay shifted, becoming sharper, more aggressive. He used the [Flowing Water Sword Art], his blade moving in smooth, relentless curves meant to deflect and redirect force. But how do you redirect a thunderclap?
Xiao An's next swing was a downward smash, more axe than sword. The young master crossed his blade to block.
The impact was different this time. A sharper, more brittle sound cut through the rain's patter.
They disengaged, a few feet of space opening between them. The young master looked down at his sword.
A hairline fracture, glowing with a faint, residual blue heat, snaked from the midpoint of his prized, spirit-tempered blade towards the hilt. It was a tiny thing. But in the muted light, it looked like a scar across the face of the moon.
Silence, thick and disbelieving, fell over the courtyard. The only sounds were the relentless rain and the ragged pull of Xiao An's breath. His ribs screamed now, the adrenaline receding. His arm trembled from the backlash of his own technique. The [Thundering Thunderbolt Sword] was a beast that bit its master as readily as its enemy.
The young master stared at the crack. His handsome face went pale, then flushed a deep, violent red. The carefully cultivated aura of superiority shattered, revealing the petulant, furious child beneath. The sword wasn't just a weapon; it was a symbol. And a gutter rat had just marred it.
His head snapped up. The look in his eyes wasn't just anger. It was pure, undiluted hatred, the kind that burns away all reason.
"You… you vermin," he whispered, the words dripping with venom. Then his voice rose to a shriek, cutting through the rain. "WHAT ARE YOU GAPING AT? KILL HIM! SURROUND HIM AND CUT HIM TO PIECES!"
The order broke the stunned stillness. The three disciples, their fear of their young master now outweighing their fear of the lightning-wielding freak, shook off their hesitation. Their swords came up, not with individual challenge, but with grim coordination. They began to fan out, not attacking yet, but moving to block the exits from the courtyard, to hem him in from all sides.
Xiao An's heart hammered against his bruised ribs. The brief, explosive advantage was gone. The thunder was spent, for now. His muscles felt like waterlogged rope. He was cornered, exhausted, and the glint in the young master's eyes promised nothing short of a slow, brutal end.
He tightened his grip on his sword, the hilt slick with rain and sweat. The disciples closed their circle, step by careful step.
The young master raised his cracked sword, pointing it directly at Xiao An's heart, a silent promise of the agony to come.
And from the shadowed archway of the main hall, a new voice, dry as ancient paper and cold as a tomb, cut through the tension.
"A Thundering Thunderbolt Sword… in the hands of a stable boy. How… interesting."
Every head, including the young master's, whipped towards the sound. Standing there, having watched the entire exchange unseen, was Elder Mo, his eyes like chips of black ice fixed directly on Xiao An.
