Tang Yuan didn't hesitate.
"Full defense formation," he said, voice carrying clean across the courtyard behind him, and the response was instant — disciples who moments ago had been standing in loose, nervous clusters snapping into practiced positions along the inner wall, elders forming up at the gate itself, the entire sect reorganizing itself into something resembling a fighting force in the space of a few frantic heartbeats.
"You're outnumbered four to one," Jiang Feiyu said, almost gently, watching the scramble with the calm of a man who'd already run every version of this outcome in his head. "This doesn't have to be a battle, Sect Master. Hand him over, and everyone behind you walks away from this gate alive."
"Everyone behind this gate," Tang Yuan said, "has already decided what kind of sect they want to be remembered as. I suggest your delegation reconsider whether a fourth-tier sect's stubbornness is worth the resources Blackstone will lose proving a point."
Jiang Feiyu's expression cooled by several degrees. "That's a mistake."
"Then let's find out," Tang Yuan said, and raised his hand.
The formation array built into the sect's outer wall — the same one that had failed hours earlier against something the wards weren't built to recognize — flared to full strength this time, silver-white light racing along every ancient channel in response to a threat it actually understood. Xiao Chen felt the air itself tighten, qi gathering along the wall's length into a barrier that hummed with the accumulated defensive work of generations of Azure Cloud disciples.
"Get him inside," Su Rou said, already pulling Xiao Chen back from the gate itself, sword drawn, positioning her body between him and the massing black-armored ranks beyond the wall. "You're not fighting this one. You don't have the cultivation base for it yet, and I am not explaining to your mother why I let you die in your first real battle."
"I'm not planning to fight it head-on," Xiao Chen said, letting himself be pulled but not stopping his own assessment of the field — the formation's strength, the numbers on both sides, the specific, deliberate way Jiang Feiyu's forces had positioned themselves to cut off every obvious retreat route. "I'm planning to make sure there's still a sect standing when this is over."
Su Rou shot him a sharp look but didn't argue further, because the first strike had already landed.
It came from Blackstone's side — a wave of qi-infused arrows arcing over the wall in a coordinated volley, and Azure Cloud's barrier absorbed the impact with a shudder that ran through the ground itself, silver light rippling outward from each point of contact like water struck by stone. The formation held, but Xiao Chen saw, even from this distance, the way the light dimmed fractionally with each impact, the wall's ancient defenses straining under a coordinated assault they hadn't faced in generations.
"It won't hold against a real breach attempt," Xiao Chen said, half to himself, watching the pattern of the volleys with the same cold analytical focus he'd once given actual war formations. "They're testing it. Softening it. The real attack hasn't started yet."
"How would you know that?" Su Rou said, sharp, not quite accusing, more genuinely startled by the certainty in his voice.
Xiao Chen didn't have a good answer that wouldn't require explaining forty years and a death he hadn't told her about yet, so he gave her the only piece of it that mattered right now. "Because that's what I'd do," he said. "And I don't think Jiang Feiyu got to Core Formation at nineteen by being predictable in the boring ways."
As if summoned by the observation, the volleys stopped.
Silence spread across the field in their place, heavy and deliberate, and through the thinning smoke of the wall's defensive light, Xiao Chen watched Jiang Feiyu step forward alone, ahead of his entire delegation, sword drawn now, qi visibly coiling around his blade in a dense, controlled spiral that made even Tang Yuan's expression sharpen with real concern.
"Sect Master Tang," Jiang Feiyu called, voice carrying easily across the distance, "I did warn you this would be a mistake. I'm going to open your wall myself, and I'd genuinely prefer it if you called off this defense before more of your disciples get hurt proving a point that was never going to change the outcome."
"Sect Master," one of the elders said urgently, low enough that Xiao Chen barely caught it over the wind, "that's a Sword Intent manifestation. Full Core Formation output. Our wall wasn't built to withstand a direct strike at that level, not without—"
"I'm aware," Tang Yuan said grimly, already forming a second seal, sweat beading at his temple despite the cold morning air. "Reinforcing the array now. Everyone brace."
Jiang Feiyu raised his blade.
Xiao Chen felt the qi gathering around it from fifty yards away — a dense, focused pressure entirely unlike the faceless thing's formless dread; this one sharp and precise and unmistakably lethal, aimed with the confidence of a genius who had never once needed a second strike to finish what he started.
"Su Rou," Xiao Chen said quietly, watching the blade begin its downward arc, "how strong is that wall, actually?"
She didn't answer immediately, which was answer enough.
The sword came down, and the world went white.
