“Ten days from now.”
Wei Jingzhe’s posture, usually a monolith of contained force, shifted, a slight tensing in his shoulders. “A date is a variable, Shen Lanyin. The ‘Nightfall Decree’ is an impossibility. An eclipse, fabricated by man? The celestial mechanics of such a feat are beyond even the most powerful mages.” His voice, always low, carried a thread of deep-seated skepticism honed over a lifetime in a realm where celestial portents held absolute sway.
Lanyin regarded him steadily. “The mechanics are simple physics, not magic. The court uses crude shadow plays and optical illusions. My father, Shen Zhaoying, refines them with superior craft. He does not manipulate the heavens; he manipulates the perceptions of those who observe it.” She picked up the sheepskin, tracing a constellation pictogram. “The populace presumes the sun itself bows to imperial decree. They imagine a flickering lamp in a deep cavern is a spirit rather than a reflection. It requires little effort to convince the uninformed of an omen when their information is so carefully controlled.”
Wei Jingzhe remained unconvinced, his gaze distant, fixed on the distant, newly sun-drenched canyon walls. “You speak of ‘physics’ and ‘optics’ as if they are tangible entities. I see only a realm ruled by unseen forces and ancestral rites. To claim an eclipse can be faked is to spit upon generations of tradition.”
“Then I will make it tangible,” Lanyin declared, her voice devoid of inflection. She found his stubborn adherence to superstition a fascinating, if irritating, obstacle. A variable that needed to be accounted for. “Your private quarters are the darkest rooms in this estate, are they not? No light, no windows, only thick, solid stone.”
He turned back to her, a flicker of curiosity in his eyes. “They are. Few enter, and none without my leave. They are kept in absolute darkness for my… comfort.”
“Excellent. That is what I require,” Lanyin stated. “I will construct an apparatus to expose these forces, not as sorcery, but as the transmission of rays.” She held his gaze with cold certainty. “I will demonstrate how a simple lens, an aperture, and an unlit room conjure visions that deceive the senses.”
Over the next two days, Lanyin commandeered a small contingent of fortress artisans under her strict direction. Inside Wei Jingzhe’s pitch-black inner sanctum, she instructed them to coat an entire wall with a fine, smooth chalk-lime mixture, then let it set completely. Its surface became a uniform, matte canvas.
Next, on the opposite wall facing the outer grounds, Lanyin directed the drilling of a single, minute perforation no larger than a grain of rice. Her calculations for its bore and placement balanced the distance to the whitewashed wall against external brightness and focal clarity. She rejected several attempts, checking each bore with a fine silken thread and a sliver of polished obsidian until the cut met her exact specifications. Around it, she had a thick, light-blocking screen of woven felt installed, allowing for controlled light entry.
“The wider the puncture, the brighter but blurrier the image. The narrower, the sharper but dimmer,” she explained to a bewildered stonemason, who could only nod mutely. “It’s a trade-off, like all physical systems. Optimizing for clarity is paramount in this instance.”
Finally, the day came for the demonstration. Wei Jingzhe entered, the air smelling of fresh lime. The space remained an oppressive void. He moved by instinct, his movements fluid and silent in the absolute dark. Lanyin stood near the whitewashed wall, a small, carefully shielded oil lamp at her feet, casting only a faint, localized glow that did not escape her immediate vicinity.
“Officer,” Lanyin said through the dark, calm and even. “Observe the wall. Do not allow your mind to impose its learned biases. Treat this as a raw data input.”
She signaled to an unseen runner, who removed the felt covering outside. For an instant, nothing happened. Then, as Wei Jingzhe’s vision adjusted, a faint, shimmering picture coalesced across the whitewashed plaster. It hung inverted and reversed left-to-right, yet unmistakably mirrored the compound's open grounds.
Stable hands crossing the flagstones appeared to walk across the ceiling. A sentry leading his patrol marched headfirst toward the floor joists. The familiar archway of the main gate hung upside down. Daylight, filtered through the minute puncture, rendered every detail with uncanny clarity: floating dust, the grain of wet cobbles, the sway of the mast banner.
Wei Jingzhe halted, his breath held. He had faced assassins and rebellions, yet this simple cast image rattled his composure. His eyes, accustomed to processing information in near-total darkness, devoured the impossible sight. He reached out, palm flat, touching only dry chalk-lime plaster. He drew his fingers back, head tilting, his expression unreadable in the low spill from Lanyin’s lamp.
“This… this is a sorcerer’s trick,” he breathed, his voice an uncharacteristic whisper. “A vision conjured from the void.” There was no anger, no skepticism now, only a raw, profound awe. He saw the mundane made magical, the familiar transformed into a spectral dream. His lifelong assumptions frayed under the silent assault of light.
Lanyin watched him, a dispassionate observer of a complex reaction. The awe, the wonder, the vulnerability etched on his severe face—they were not variables she had accounted for in her equations. This was an emotional output, a human response, and it did not fit her logical framework. It was… messy. Disorienting. Her own rigidly logical mind felt a strange, unsettling ripple, a discordance she struggled to categorize.
“It is not sorcery,” she stated, anchoring herself to the demonstration. “It is straight-line radiation passing through an aperture to form an image. The world outside, inverted against your wall. Your senses perceive an illusion, but it is only the geometric behavior of light.” She gestured toward the upside-down courtyard. “Imagine this principle scaled. Magnified. A focused simulation of the sun, or an eclipse cast across the sky by an aligned lens when my father's faction requires it.”
As she spoke, an anomaly entered the illuminated scene. An unnatural gray haze crept across the flagstones, clinging low. It drifted too dense and localized for morning mist. Through the pall moved figures—not garrison guards, but lean, dark silhouettes slipping forward in absolute silence. They carried curved blades, catching the projected light with a glint of polished obsidian.
Wei Jingzhe’s eyes, fixed on the inverted scene, narrowed. He saw the artificial fog, the unnatural silence of the figures. One of them, a lean, cloaked individual, moved with horrifying purpose towards the archway. An outer guard on sentinel duty stood stationary against the wall. Without a sound, the cloaked shape drew across the sentry's throat. The body collapsed, a silent drop within the inverted beam of light. Then another, and another.
“Consort Baiyu,” Lanyin murmured, her voice flat, devoid of surprise. “Her vanguard. They are already inside your perimeter.”
