The world stopped. Master Wen's words hung in the air, delicate and deadly as a spider's thread. An allergic reaction to the Snow Lotus. It was a perfect, brilliant, and utterly horrifying move. It transformed their only hope into a death sentence, rendering their entire elaborate scheme to start a plague completely useless. The plan wasn't just checkmated; it was flipped on its head and set on fire.
For a fraction of a second, the mask slipped.
It wasn't a grand, dramatic crack. It was a tiny, almost imperceptible falter. Yingluo, who had been the picture of stoic, noble grief, felt the blood drain from her face so fast that the room swam. Her hand, which had been resting calmly on the back of a chair, clenched so tightly that her knuckles turned white. A single, unguarded gasp of pure, raw panic escaped her lips before she could bite it back.
It was a mistake. A fatal, human imperfection.
And Master Wen saw it.
His kind, scholarly eyes didn't change, but she felt his gaze sharpen, the way a hawk's does when it spots a mouse in the grass. He had seen the flicker of raw, uncalculated fear. He had seen the strategist behind the grieving lady.
But in that same instant, Yingluo's mind, honed by a lifetime of future trauma, snapped back with a vengeance. The panic was a tidal wave, but she was a cliff. She let the wave crash against her, and then she used its receding force to propel her into a new, more desperate performance.
"An… an allergy?" she whispered, her voice now not just sad, but laced with a fresh, new horror. It was the sound of a mother who had just been told the only medicine for her dying child was poison. She took a half-step back, as if the diagnosis itself were a physical blow. "Gods… no. It cannot be."
She looked from the physician to Li Xun, her eyes wide with a perfect, staged despair. "Your Highness… did you hear? It is a cruelty beyond imagination. To think the cure itself would be his end." She turned back to Wen, her hands clasped together in a gesture of pleading. "Master Wen, you are the most learned physician in the realm. There must be something else. Another root? Another… anything?"
This was her new strategy. Abandon the cold, resilient lady. Become the desperate, grieving noblewoman, driven to the brink of hysteria by a twist of fate so cruel it could only be divine punishment. She was no longer a schemer; she was a victim. And in her desperation, she would be careless. She would reveal things she shouldn't. It was a trap, but she was the bait.
Wen's expression softened into one of profound, professional sympathy. He had taken the bait. "My Lady, my heart breaks for you. But medicine is not magic. The body is a complex system. Sometimes, the cure and the poison are two sides of the same coin. To give him the root would be to speed his end. I am truly sorry."
He began to pack his instruments, his movements slow and respectful, giving her time to "process" the tragedy. Li Xun stepped forward, placing a comforting hand on her shoulder. "We will not lose hope, Lady Wei," he said, his voice the perfect blend of royal strength and personal compassion. He was playing his part to perfection.
Shen Miao escorted the physician from the room, and the moment the door closed, the performance ended.
"The allergy is a lie," Yingluo said, her voice once again cold and sharp as shattered glass. The frantic energy of her performance vanished, replaced by a chilling, analytical calm. "It is too perfect. Too convenient."
"I agree," Li Xun said, his brow furrowed in thought. "The 'Silent Frost' poison is designed to be undetectable. To create a symptom that is the direct opposite of its cure is a level of biochemical genius I find hard to believe. It's a narrative construct, not a medical one."
"It's a narrative designed to make us give up," Shen Miao added, pacing the room like a caged tigress. "To send us back to the drawing board, while the boy's time runs out. He is a dead man walking, and they know it."
"Not necessarily," Yingluo said, a new, dangerous idea taking root. She walked to the small table and poured a cup of cold water, her hands steady. "Wen is a physician. A brilliant one. And like all brilliant men, he is proud. He wanted to see us squirm. He wanted to enjoy his intellectual victory. In his arrogance, he may have given us the key."
"What key?" Shen Miao demanded.
"The name of the poison itself," Yingluo said. "'Silent Frost.' It is an obscure name, not found in any common medical texts. It is a name from the shadows." She looked at Li Xun. "Your Highness, your network of scholars and spies… have you ever heard of it?"
Li Xun was silent for a long moment, his eyes distant, searching through the vast library of his mind. "'Silent Frost'," he murmured, testing the words. "It sounds familiar. Not as a poison, but as a failed medical experiment. Decades ago. A physician tried to create a tonic that would slow the heart rate in patients with fevers, to conserve their strength. The formula was unstable. It didn't slow the heart; it crystallized the blood in the extremities. The patients would die from frostbite in the middle of summer. The project was buried, the physician disgraced."
"But the formula wasn't destroyed," Yingluo finished, her eyes gleaming. "The Empress's family got a hold of it. They refined it, made it more subtle, and turned it into a weapon. And Wen, being the Empress's pet, would know its true history. He knows its origins, which means he might know its weaknesses."
This was the new thread. The mystery was no longer just about getting the root; it was about uncovering the poison's history. It was a strategy shift from a heist to an investigation.
They had to let Wen go. He had to report back to Li Jian with the story of the broken, desperate Lady Wei. But before he left, she had to give him one more piece of cheese to take back to his master.
She found him in the main room, receiving a cup of tea from Shen Miao. She rushed in, her eyes wild, her hair slightly disheveled.
"Master Wen, wait!" she cried, her voice a desperate whisper. She grabbed his sleeve, a gesture of shocking impropriety for a noble lady, but perfect for a woman on the edge. "I… I remembered something. My grandmother… she had a book. A book of old, forgotten remedies from the western tribes. There was a mention of a wasting sickness… a 'cold fire' that could only be treated with a… a blood purge. Using the venom of a… a desert scorpion mixed with… with wolf's bane."
She was inventing it all, spinning a fantastic, desperate lie. It was a classic scheming move, designed to send Li Jian's men on a wild goose chase to the western deserts, wasting their time and resources while the real investigation began here.
Wen listened patiently, his expression one of pitying condescension. "My Lady, your grief is clouding your judgment. Such a concoction would not purge an illness; it would cause an agonizing death. Please, rest. Leave these matters to men of science."
He gently removed her hand from his sleeve and bowed. "I will report your tragic situation to the Third Prince. I am sure he will offer his deepest condolences."
He turned and walked away, his back straight, his mission accomplished.
Yingluo watched him go, her heart still pounding. She had played her part. She had given him the false lead. She had been the perfect, desperate fool.
As he reached the lodge's outer door, he paused. He turned back, his eyes finding hers across the room. He gave a slight, formal bow.
And then he spoke, his voice just loud enough for her to hear.
"A phoenix, I have read, is a creature of fire. It is a shame when it is forced to play with frost."
