玄色马车碾过沉寂的街道，最终驶入六王府那扇沉重威严的侧门。车轮滚过青石板路的声响在深宅大院中显得格外清晰，如同碾在辛久薇紧绷的心弦上。车门开启，凛冽的寒风裹挟着王府特有的沉水香气涌入，萧珣率先下车，扣着辛久薇手腕的手依旧没有丝毫放松，力道甚至带着一种不容置喙的强硬，将她几乎是半拖半拽地带下了车。

"Your Highness!" Liu Ya was already waiting inside the door, his face pale with the aftermath of the ordeal and filled with deep self-reproach. Seeing Xin Jiuwei's bloodied left shoulder and pale face, his eyes were filled with even more guilt. "Miss Xin, she..."

"Summon the royal physician." Xiao Xun's voice was flat, interrupting her. He didn't even look at Liu Ya; his deep gaze, like a cold probe, fell on Xin Jiuwei's tightly pursed lips and her face, pale with anger and blood loss. He gripped her wrist, not heading towards the secluded courtyard where she had previously lived, but directly towards the "Qingyan Hall," deep within the palace, the most heavily guarded area and his core living quarters.

The Qingyan Hall was brightly lit, and the brazier burned brightly, dispelling the chill of the winter night. However, this warmth could not melt the icy chill that permeated Xin Jiuwei's body. Xiao Xun led her into a side room, which was simply furnished but exuded an extraordinary atmosphere, clearly a place where Xiao Xun handled urgent matters or took a short rest.

Xiao Xun finally released her grip. Xin Jiuwei immediately took a step back, distancing herself from him as if he were some deadly plague. The lingering pain from his cold finger marks on her wrist and the almost crushing force of his grip clearly reminded her of the humiliation she had just suffered. She straightened her back, raised her chin, and stared intently at Xiao Xun with eyes burning with cold anger and wounded stubbornness, silently accusing him of deception and tyranny.

Xiao Xun seemed oblivious to her glare. He took off his black fox fur cloak, which was stained with snow and had a faint smell of blood, and casually handed it to the servant standing respectfully with his head bowed beside him. Underneath, he wore only a dark brocade robe with dark cloud patterns. His posture was upright, and his face, in the bright candlelight, was healthy, with a slight flush from his journey, completely unrelated to the words "critically ill."

"Sit." He gestured to a rosewood armchair with thick cushions in the room, his voice still calm and even, yet carrying an unquestionable command.

Xin Jiuwei stood motionless, like an ice sculpture. In the warm environment, the strange numbness in her left shoulder wound spread faster, mixed with waves of tearing pain, causing fine beads of cold sweat to appear on her forehead, and her body to tremble almost imperceptibly. But she gritted her teeth, forcing herself not to show any weakness.

Xiao Xun's gaze finally fell on her again, precisely catching the slight tremor in her body and the cold sweat on her forehead. His deep eyes narrowed almost imperceptibly, like a ripple on a calm lake. He did not force her to sit down again, but turned and walked to the display cabinet to the side, taking down an inconspicuous small black lacquer box.

The physician practically ran in, followed by a young apprentice carrying a medicine chest. Upon seeing Xin Jiuwei's bloodstained left shoulder and the dark purple bloodstains, the old physician's expression instantly turned grave: "The young lady has been poisoned with 'Bone-Eating Green'! This poison is potent, paralyzing muscles and corroding blood and qi; it must be treated immediately!" He disregarded the formalities and rushed forward to examine the wound.

Xin Jiuwei remained standing stiffly, unresponsive to the physician's actions, her gaze fixed on Xiao Xun's back.

Xiao Xun returned carrying the small black lacquered box. Without even glancing at the busy physician, he opened the box directly. An extremely clear medicinal fragrance, tinged with a faint bitterness, instantly filled the air, overpowering the scent of agarwood. Inside the box were several pieces of ointment, entirely emerald green, as if carved from the finest jade.

"Use this." Xiao Xun's voice was low as he handed the box to the physician, gesturing towards Xin Jiuwei's wound.

Upon seeing the emerald green ointment, the imperial physician's eyes widened in disbelief and delight: "Emerald...Emerald Ointment?! Your Highness, this is..."
