Chapter 262: Everything He Has

Xuan reached into the sleeping thing in his hands and told it to wake all the way up, and it did, and it very nearly killed him where he knelt.

Marrow Dragon came awake the way it had in the throne hall, only there was no throne hall’s worth of terror to carry him through it this time, only an empty body being asked to hold a door it had no strength left to hold.

The Dragonvein light roared up white-blue and furious along the edge. The note went out of the blade and into his bones. And the enormous, patient, ancient thing on the far side of that door leaned its weight into him, and Xuan felt his meridians scream under a power his Foundation body had no business channeling, a power that would take everything he had and then start taking things he couldn’t spare.

[ A breath, ] Mira said, and even she sounded afraid of it. [You get one breath of this, Xuan, and not a hair more, or it finishes what the mountain-blow started. Make it count. ]

He had one breath. He spent it on the only thing worth spending it on.

The Fourth had his will wrapped around the half-made cage, unmaking it pin by pin, and Xuan drove the woken sword into that grip, not at the man but at the thing the man was holding, the way the blade had reached out on its own in the throne hall. This time Xuan aimed it.

The Profound edge and the old resonance went past the Fourth entirely and struck the vault-thing he carried, and the vault-thing woke and thrashed, and the Fourth Prince, who had been calmly pulling a formation apart, suddenly had both hands full again of something fighting very hard to get loose.

He rounded on Xuan with the first real anger of the whole night. "Stop doing that."

Xuan couldn’t have stopped if he’d wanted to. The breath was already ending. The sword shut on its own, the light dying out of the edge, and the price came due all at once. Something tore loose inside him, deep, where he had nothing left to cushion it, and he folded the rest of the way down onto the terrace with blood in his mouth and his sight going white at the edges, spent past spent, a man who had now handed the fight every last thing he owned down to the marrow. Some part of him a healer would want to look at very soon, if there was ever going to be a soon, had given way for good, and Xuan did not have the strength left in him to care.

But the seconds were real. In the space the woken sword had bought, while the Fourth wrestled his prize back under control, Pei’s crew drove the array up through its final phases, one and then the next and then the last, and the cage that had been two pins short of a lock became a lock complete. Every ward lit, every flag stood, the core burning cold at the dead center of it, and the whole enormous machine they’d bled a week and a night to build arrived at the single instant it had all been for.

And it didn’t close.

Xuan felt it through the stone and through the failing light in his own eyes, the wrongness of a thing reaching the exact moment it was built for and then not doing the one thing it was built to do. The cage was whole. The lock was whole. And the lock would not turn.

’Mira—’ He could barely shape the word. ’Why isn’t it—’

[ I don’t— ] For the first time since he’d known her, Mira stopped dead mid-sentence, and what came after was worse than any answer, because she knew perfectly well, and something was stopping her from saying it. [ It’s built right. Everything’s right. The last turn needs a key, a way of shutting it that the formation doesn’t hold, and I— ] She stopped again, and there was a straining in her voice he had never once heard, as if she were shoving her whole weight against a door of her own. [ I know the key, Xuan. I know it. And I’m not allowed to give it to you. I can’t say it.]

Across the terrace, the Fourth Prince got the last of his thrashing prize back under his grip, and straightened, and looked at the complete and useless cage around him with the dawning, delighted contempt of a man who has just watched his enemy loose their whole quiver and miss.

"It won’t close." He said it almost kindly. "You built the entire beautiful thing, and it won’t turn. Do you know, I honestly wondered whether you had it in you, and you very nearly did." He stepped toward the core, toward the boy bleeding his last out onto the stone beside it, and the finished wards parted around him as though they’d never been anything at all. "Nearly isn’t the word anyone remembers, though."

Across the terrace, the fighting faltered as they understood it one by one, the people who’d spent their bodies buying the seconds that built the thing. Xinhua on her knees with her sword still somehow up, Yan Wuji swaying on ribs stove in, Bo Ren dragged back onto his keystone by pure stubbornness and feeling the pin beneath him refuse to bite. They had done the impossible and gotten it built, and now it stood around the Fourth Prince finished and lit and useless, a magnificent lock with nothing on this earth to make it turn.

Xuan lay on the old terrace with blood cooling on his lips and every card in the deck face-up and spent, and listened to the one voice in the world that could still save them straining against a rule it could not break, and understood that they had done all of it right. Built it true. Spent everything they had, and a few things they didn’t.

And it still wasn’t going to be enough, because the last piece was locked inside the one place on that whole terrace none of them could reach.
