The Equation of Ashes

They track the sky’s oldest echoes from an observatory built to outlast its inhabitants. But the signals have stopped being passive noise. They've started answering back—and they are charging a price.

Su Jianting, a bodyguard whose intellect sharpens exactly when a situation goes to hell, is paid to keep an aloof researcher breathing until their extraction date. It should be a ninety-day lockdown with tight rations and bad coffee. But the station doesn't run on electricity alone; it runs on the Binding Statute. It is an absolute, unbending rule of mathematical equity that demands equal measure for every action, emotion, and sound. Technically just. Practically monstrous.

When the signals translate their first cost and a technician is taken as equivalent exchange, Jian realizes the count is unbroken. They have seventy-two hours before the system demands the final structural settlement. Trapped with a skeleton crew, a vanishing timeline, and an unseen logic that enforces terrifying parity, Jian must outwit the station's architecture without triggering a response that prices them all out of existence. Every choice claims a terrible symmetry. Every silence is logged. And the sky refuses to shut up.
