2. The Vermilion Stain

The steward did not return.

Zimo remained in Luoyue Pavilion for three days, though no one ordered him to stay and no one gave him leave to go. The compound had fallen into a strange, suspended state—not quite lockdown, not quite chaos. Servants still brought food, cold millet porridge and salted vegetables left outside the door screen on a lacquer tray. The guards still stood at the outer gate, their halberds glinting in the thin winter sun. But the rhythms of the household had collapsed. Zimo heard no laughter, no conversation, only the occasional urgent murmur of voices and the rapid scuff of feet crossing the courtyard gravel.

On the second day, he learned the details from a kitchen girl who whispered through the screen while he ate. Gongmeng Zhi had been struck down at the temple gate precisely as the dawn rites began. Three men had set upon him—their faces masked, their blades curved like harvest sickles. They had escaped before the temple guards could organize pursuit. Duke Ling, upon hearing the news, had fled the capital with his personal retinue, fearing a wider coup. The city was now ruled by rumor: some said Qi Bao had seized the treasury, others that Beigong Xi had thrown his lot in with the assassins, still others that the Duke’s exile was temporary and his army was already marching back.

The kitchen girl’s voice trembled. “They say the killers painted marks on the temple pillars. Cinnabar marks. Like a curse.”

Zimo said nothing. He knew exactly what marks those were. He had spent days copying them.

On the third morning, the screen door opened and Qi Bao entered, not alone. Behind him came two other men. The first was Beigong Xi—taller than Qi Bao, younger, his beard still black and trimmed to a perfect point, his robes of the finest patterned silk. His eyes were restless, flicking around the pavilion as if expecting attack from the shadows. The second man Zimo did not recognize. He was older, thick-bodied, with the weathered hands of someone who worked with metal. His tunic was plain, but the bronze seal hanging from his belt marked him as a master artisan of the ducal foundry.

“Sit,” Qi Bao said, gesturing to the cushions around Zimo’s worktable. “All of you.”

They sat. Zimo remained on his knees beside the half-finished silk panel, his hands folded in his lap. The copy of the mural loomed over them like a silent accusation. In three days, he had completed perhaps two-thirds of the composition. The swallow’s body was fully rendered now, its cinnabar wings spread wide. Only the lower altar and the kneeling patriarch remained as pale under-drawing, waiting for color.

Qi Bao studied the copy for a long moment. Then he turned to Zimo. “Your work is excellent. More than excellent. It is convincing.”

Zimo inclined his head, the barest acknowledgment.

“Circumstances have changed,” Qi Bao continued. “The original mural has been... damaged. In the confusion at the temple, someone defaced it. The Duke’s men, perhaps, or looters. The sacred image of the Gongmeng line is now a ruin of chipped pigment and gouged plaster.”

Beigong Xi shifted on his cushion. “A tragedy,” he said, and his voice carried no grief whatsoever.

“A tragedy indeed,” Qi Bao agreed. “But your copy, painter—your copy survives. When the Duke returns, he will ask to see the ‘Auspicious Omen.’ The ritual must continue. The blessing must be preserved. Do you understand what I am telling you?”

Zimo understood perfectly. The original was destroyed. His copy would be presented not as a reproduction, but as the authentic mural—somehow rescued, somehow restored. The hidden marks, the coded plan of assassination, would be buried under the veneer of sacred art. Qi Bao was not merely asking him to finish the copy. He was asking him to create a new original, one that erased the evidence entirely.

“I am a copyist, my lord,” Zimo said carefully. “My skill is in replication, not invention.”

“Then replicate.” Qi Bao’s voice hardened. “The mural as it was before the damage. As it was meant to be. Pure. Unblemished. You will paint over the anomalies.”

The word hung in the air. Zimo felt his blood chill. Qi Bao knew. He knew about the hidden marks, the schematic of the temple gate, the brown-red positions of the attackers. He knew that Zimo had seen them. And he was ordering them erased.

The master artisan cleared his throat. He had been studying Zimo’s pigments, the little clay dishes of ground mineral arranged by color. “The cinnabar is good,” he said, his voice a low rumble. “Southern mines. But the binding medium is wrong. Too much fish glue. It will crack within a decade.”

Qi Bao raised an eyebrow. “Can you correct it?”

“I can,” the artisan said. “I can make a medium that will age the pigment instantly—give it the craquelure of two centuries. The Duke’s examiners will find no flaw.” He looked at Zimo with something that might have been respect or might have been pity. “But the painter must work quickly. Once the medium sets, it cannot be altered.”

“Then we are agreed,” Qi Bao said. He rose, and the others rose with him. “Zimo will complete the copy—the new original—with all anomalies removed. Master Shi will provide the aging medium. Beigong Xi will ensure that no one disturbs this pavilion until the work is done. When the Duke returns, the ‘Auspicious Omen’ will hang in its rightful place, a testament to the Gongmeng line’s enduring blessing.”

He paused at the door screen, his back to Zimo. “One more thing, painter. The kitchen girl who spoke to you yesterday—she has been reassigned. You will receive your meals from a guard now. Do not attempt to speak to anyone else. Do not attempt to leave. Your mother, I understand, resides in the potters’ quarter. It would be a shame if her health suffered during this difficult time.”

Then he was gone. Beigong Xi followed. Only Master Shi remained, already opening his satchel of vials and implements, already beginning to measure the poisonous chemistry that would turn a forgery into history.

Zimo worked.

He had no choice. His mother’s face floated before him every time he lifted the brush—her gnarled fingers, her patient eyes, the small room in the potters’ quarter that smelled of kiln smoke and dried herbs. She had sold herself into servitude to pay for his apprenticeship with the old master painter. She had walked three miles every week to bring him pickled vegetables wrapped in lotus leaves. She had never once complained about her ruined hands or her bent back. She had only said, “Paint well, my son. Make something that outlasts us both.”

So he painted.

Master Shi’s aging medium was a foul-smelling concoction of alum, ox bile, and something he called “dragon’s tears”—a mineral salt imported from the western tribes that accelerated the oxidation of organic binders. Mixed into the cinnabar, it made the paint settle into the silk with an eerie, instantaneous antiquity. Within hours of application, the fresh strokes developed micro-cracks identical to those in genuine ancient works. The colors muted slightly, losing their new-made brightness. The silk itself seemed to age, taking on the amber tone of centuries.

Zimo hated it. He hated the way the medium made his brush drag, the way it corrupted the purity of his pigments. But he could not deny its effectiveness. By the fourth day, the completed swallow looked exactly like the original—not the defaced original, but the original as it should have been, as it had been before Qi Bao’s conspirators layered their deadly code into the pigments.

He had erased the brown-red marks. He had painted over the schematic lines in the malachite clouds. The temple gate was gone, replaced by an innocent swirl of celestial mist. The tiny character that meant “to wait” had been submerged under a fresh layer of azurite blue. The hidden plan of assassination no longer existed anywhere except in Zimo’s memory—and in the tiny square of silk still pressed into the heel of his wooden clog.

At night, when Master Shi had retired to his guest quarters and the guards had settled into their watch, Zimo worked on his own project.

He had found a roll of waste silk among the supplies—scraps too small for the main copy, discarded by Master Shi as unusable. On these scraps, using a brush of only three hairs, Zimo began to paint the truth. Not the erased truth, but the truth that lay beneath it. He painted the temple gate from the hidden schematic. He painted the brown-red marks, the waiting positions, the attack choreography. He painted three masked figures with curved blades. And in the corner of each scrap, he painted a tiny self-portrait—not his face, but his eye, open and unblinking, the same eye he had hidden in the border of the main copy.

These scraps he folded into origami birds—the dark swallow of the mural’s omen—and concealed them in the hollow bamboo sections of his brush holder. If he died, someone might find them. If he lived, they would be his testimony.

On the sixth day, Beigong Xi returned alone.

He came at dusk, when the pavilion was lit only by the single oil lamp on Zimo’s table. Master Shi had gone to the foundry to procure more mineral salts. The guards had retreated to the outer gate to eat their evening rations. Zimo was alone, putting the final touches on the kneeling patriarch’s robes.

Beigong Xi did not announce himself. He simply pushed through the door screen and stood, his shadow enormous on the mural wall. His eyes were red-rimmed, his breathing uneven. He had been drinking—Zimo could smell the sour plum wine on his breath from across the room.

“Is it finished?” Beigong Xi demanded.

“Nearly, my lord. The patriarch’s face remains.”

“Show me.”

Zimo stepped aside. Beigong Xi approached the silk panel and stared at it for a long time. His expression was strange—not satisfied, not relieved, but something more complicated. Grief, perhaps. Or guilt. Or both.

“He was my friend,” Beigong Xi said suddenly, his voice thick. “Gongmeng Zhi. We studied together as boys. He taught me to shoot a bow. He laughed at me when I missed.” He pressed his palm against the edge of the worktable, steadying himself. “And I stood aside. I knew what Qi Bao planned, and I stood aside.”

Zimo said nothing. There was nothing to say.

“You think I am a coward,” Beigong Xi went on. “You are right. But you do not understand Qi Bao. He does not make threats. He makes certainties. If I had warned Gongmeng Zhi, my entire household would have been slaughtered—my wives, my sons, my infant daughter. Qi Bao made that very clear. He showed me the list of names. He showed me the blades that had been assigned to each throat.”

He turned to face Zimo, and his eyes were wet. “So I chose. I chose my family over my friend. And now I must live with that choice, and bury it, and pretend to the Duke that I am still his loyal servant.” He gestured at the silk panel. “This painting—this lie you are creating—is my burial shroud. Do you understand? It will hang in the temple for centuries, and every time someone kneels before it to pray, they will be praying to my guilt.”

Zimo looked at the painting. The patriarch’s face was still blank, a pale oval waiting for features. In his mind, he saw the hidden eye he had placed in the border, the tiny witness that would outlast them all.

“My lord,” he said quietly, “a painting is not only what it shows. It is also what it hides.”

Beigong Xi stared at him. “What do you mean?”

Zimo hesitated. He was standing on the edge of a precipice. Beigong Xi was drunk, emotional, vulnerable—but he was also one of the conspirators. If Zimo revealed too much, he could be killed before dawn. If he revealed too little, he might miss his only chance to plant a seed of doubt in the faction that held him prisoner.

“The original mural,” Zimo said carefully, “contained hidden marks. I saw them while I was studying it. Marks that showed the temple gate, and positions of attack, and a character that meant ‘to wait.’ Qi Bao ordered me to erase them. But I wondered, my lord—who put those marks there? And why?”

Beigong Xi’s face went pale. “You saw them?”

“I saw them. Every one.”

“And you erased them?”

“I erased them from the copy,” Zimo said. “But someone else must have painted them originally. Someone else must have known the plan well enough to encode it into a sacred mural. If that person still lives, my lord, then the Duke has a witness. And Qi Bao has a rival.”

Beigong Xi was silent for a long time. The lamp flickered, sending shadows dancing across the walls. Outside, the cypress needles continued their dry, papery rustle against the roof tiles.

Finally, Beigong Xi spoke. “The marks were painted by Chushi Pu. He is a minor noble, a cousin of Qi Bao’s wife. He fancies himself an artist, but his talent is mediocre. Qi Bao used him to alter the mural because he was the only one with access to the temple who could hold a brush. After the assassination, Chushi Pu fled the capital. No one knows where he is.”

He straightened, and some of the drunkenness seemed to fall away from him. His eyes sharpened. “Why are you telling me this, painter? What do you want?”

“I want to survive,” Zimo said honestly. “When the copy is finished, I become a liability. Qi Bao has already threatened my mother. I have no reason to believe he will let either of us live once the Duke accepts the painting as authentic.” He met Beigong Xi’s gaze. “But if the painting contains a secret that only I can reveal—a secret that implicates Qi Bao but not you—then I am more valuable alive than dead.”

Beigong Xi’s expression shifted. Something calculating entered his eyes, a nobleman’s instinct for political advantage reasserting itself over his drunken guilt.

“Show me,” he said.

Zimo went to his brush holder and extracted one of the origami birds. He unfolded it carefully, revealing the tiny painting inside—the temple gate, the attack positions, the three masked figures. Beigong Xi studied it by the lamplight, his breathing slow and measured.

“This is accurate,” he said. “This is exactly how it happened.”

“There are more like it,” Zimo said. “Hidden where no one will find them unless I choose to reveal them. If I die, they will surface. I have made arrangements.” This was a lie—he had made no arrangements at all—but Beigong Xi did not need to know that.

The nobleman folded the scrap and handed it back. “Keep your birds, painter. Finish the copy. When the Duke returns, I will ensure that you are called to testify about the painting’s authenticity. Say nothing of the hidden marks unless I give you the signal. Do you understand?”

“What is the signal?”

Beigong Xi smiled thinly. “You will know it when you see it.”

He left without another word. The door screen settled back into place. The lamp continued to flicker. Zimo sat down heavily on his cushion, his heart pounding against his ribs.

He had just made an ally—or an enemy. He could not yet tell which. But he had bought himself time, and time was the only currency that mattered now.

He picked up his brush and turned back to the silk panel. The patriarch’s blank face stared up at him, waiting to be given features. In the ancient tradition, the kneeling supplicant should resemble the clan founder—a remote, idealized ancestor with the stern brow and flowing beard of archaic nobility. But Zimo had a different idea. A dangerous idea. An idea that would transform this painting from a simple forgery into a weapon.

He mixed a fresh dish of flesh-toned pigment—kaolin white with a touch of cinnabar and yellow ochre—and began to paint.

The face that emerged beneath his brush was not the face of an ancient patriarch. It was the face of Qi Bao. The high brow, the watchful eyes, the beard streaked with white like snow on a mountain. Zimo painted him kneeling in supplication before the dark bird, his hands raised in an attitude of prayer, his expression caught somewhere between reverence and terror.

If anyone looked closely, they would see it. If no one looked closely, the painting would pass as an authentic ancestral portrait. But Zimo would know. Qi Bao, when he saw it, would know. And someday, perhaps, the Duke would know too.

He set the brush down just as dawn began to lighten the lattice windows. The patriarch—Qi Bao—gazed up at the cinnabar swallow with frozen, pleading eyes.

The copy was complete.

And hidden in its pigments, layered beneath the aged surface and the sacred imagery, was a truth that would burn through the court of Wei like fire through dry silk.
