Winter settled over Chang'an, deep and quiet. Once I could walk and with the aid of my new simple cane, I returned to my courtyard at The Garden of Serene Thought. My cane gun was now half its original length and cracked lengthwise along the barrel along the seam. I’d had the foresight to reinforce the handle end, and frankly I was quite lucky to still have a hand.

  Empirically it could have gone worse, but I wasn’t left with much faith in Tang Dynasty steelworking techniques for future firearm development. I found myself worried about knowledge of my new weapon getting out, but comforted myself knowing anyone who tried to copy the design, even the skilled smith I hired, would be more likely to blow off their own hand than kill their enemy. They also wouldn’t know how to make the black powder with any degree of purity.

  I wondered when Lord Feng would hear of my new invention.

  So, instead I mostly worked with Wang's stern auditors, my mind the key that unlocked the convoluted poison of Song's accounting. By night, I worked out with Xiao Kai at home, and she regularly lent me her qi to help guide my own cultivation.

  Qi was… interesting, Xiao Kai spoke of it like a system of generation and then routing. I felt like by circulating my qi it was stretching out little pipes within my body, that slowly widened over time. Slowly, the borrowed Qi began to flow more smoothly, like more paths had been opened.

  Generating Qi, however, was much less intuitive and progress was vastly slower. Even after many moons, I couldn’t really work out how to generate more volume, Xiao Kai’s energy felt dauntingly vast in comparison.

  In the quiet of our own courtyard, I presented the dark-bladed jiàn to Xiao Kai. She took the sword, her hands tracing the flawless lines of the weapon I had nearly died wielding. She was speechless, her eyes shining with an emotion too profound for words. She simply gave me the deepest, most formal bow I had ever received from her, accepting the trust the gift represented.

  After that I saw her practice her sword forms daily.

  One cold afternoon, two months later after what would be that season's last snow, Steward Feng appeared in the doorway as silently as a shadow.

  “Scholar Zhang,” he said, his tone flat, perhaps mildly annoyed. “You have a visitor. The Master has… granted her temporary passage.”

  I looked up in surprise as he stepped aside. Layla entered the courtyard.

  The biting winter air swirled around her as she shed a heavy, charcoal-grey woolen cloak lined with pure white fox fur. Beneath, she wore a breathtaking gown of deep, shimmering plum-colored silk, intricately embroidered with silver blossoms. Despite the bitter cold, her feet were still bare, stepping gracefully onto the flagstones that Xiao Qi rushed to sweep clear of snow. She dismissed the Steward with a polite nod and walked towards me, her expression a complex mixture of relief, concern, and intense curiosity.

  “The whispers about the battle in the alleys have reached even my quiet pavilion, Scholar Zhang,” she said, her voice a serious murmur. “They speak of thunder, lightning, and a ghost with a shadowy hand.” Her eyes swept over me, noting the cane by my side. “I came to see for myself if you were still in one piece.”

  I motioned to my study, and the heat of the brazier within. She gracefully lowered herself onto a cushion near the hearth, extending her feet towards the warmth.

  “It is a strange thing,” she said, her voice soft and contemplative. “I haven't felt a cold that bites to the bone like this since I was a child. We were too poor for shoes for me then.” A wry, self-aware smile touched her lips. “I supposed the silks and heated floors of Chang'an have made me soft.”

  "I'd been meaning to ask," I said, latching onto the opportunity. "Layla isn't a Sogdian name, right?" Layla smiled knowingly and shook her head. "How knowledgeable of you. No, my father was Arabic and my mother was Sogdian." I raised an eyebrow. "And the 'Sogdian' whirl?" "I learned it from the Sogdian dance troupe I was sold to when I was eight years old," she replied as if it were the most natural thing in the world.

  I didn't know how to respond to that. Layla noticed and smiled, bitterness barely visible. Her tone shifted back to the urgent present. “Tell me what truly happened that night. I need to know what kind of new pieces are now in play on the board.”

  I told her everything. When I finished, she was silent for a long time, her eyes glimmering with a mixture of awe and fear. “A weapon that creates its own thunder… You truly are not like any man in this world, are you, Scholar Zhang?”

  “And what of you?” I deflected gently. “What happened with Vice-Director Song?”

  The light in her eyes died. She wrapped her arms around herself, unconsciously rubbing her shoulder. “I did as I promised,” she said, her voice flat and brittle. “I… entertained him.” She shivered. “I let his hot, damp hands… linger. He spoke of his plans for me, the fine golden cage he would build for his new songbird.” She opened her eyes, and they were like chips of frozen jade. “I smiled. The entire time, I smiled. And when he finally left, I scrubbed my skin until it was raw. But it worked. He was delayed for more than two hours.”

  I handed her a cup of warm tea.

  “The Censorate should have enough to start a case against Song,” I said, changing the subject. “We saved some documents, including one with his personal seal.”

  “His personal seal…” she repeated, a grim satisfaction in her eyes. “Then it was worth it. But Censor's investigation is a grinding millstone. The moment Censor Wang issues his first formal writ, the Chancellor will know his pet dog is being targeted. He will not sit idly by.”

  “When the tides of opinion turn, the Chancellor will discard Song as easily as a glove,” I said. “He'll be replaced by some new source of silver. It will be slow and then sudden, all at once.” I glanced out at Xiao Kai, who was diligently practicing a rehabilitative form in the courtyard. “I must focus on overturning the Chen Huarong case. The winter is cold and harsh on old bones.”

  Layla nodded slowly, and caught my glance at the youth in the courtyard. Her eyebrows rise for a brief moment, as if she's realised something that had been in front of her this whole time. “A patient game for a long winter, then,” she murmured.

  She rose gracefully, the meeting over. Then she paused, looking from the comforting glow of the brazier to the cold, snow-dusted flagstones beyond. A wicked glint entered her eyes.

  “It is a long way to the service gate where my palanquin waits,” she said, looking down. “A true… albeit platonic friend… would surely not ask a lady to let her newly-warmed toes touch the frozen ground again, would he?” She glanced at my healing side. “You are still recovering, of course, but I am very light.”

  The teasing challenge hung in the air. As she waited, she stepped closer, her playful smile vanishing as she leaned in to whisper, her warm breath ghosting against my ear.

  “Ten thousand taels of silver.”

  She pulled back, her expression a complex mixture of bitterness and the faintest, most fragile flicker of hope. “That is the price the Jade Grotto has placed on its prized moonstone.”

  I considered her teasing request and the impossible number she had just named. My thoughts turn to my own love and how to fulfill a request without crossing a delicate boundary. a mischievous smile of my own touched my lips. “As a friend, of course.”

  Before she could react, I bent down, hooked an arm behind her knees, and hoisted her over my shoulder in a clean, efficient fireman's carry. She was, in fact, very light.

  For a moment, there was only stunned, absolute silence. Then, a panicked, indignant yelp.

  “Zhang RuLin! What in the name of the heavens are you doing?!”

  Layla, the graceful and untouchable moonstone of the Jade Grotto, was suddenly slung over my shoulder like a sack of very expensive, very fragrant rice, her world a dizzying, upside-down view of my back. “This is… indecorous! It is… brutish!”, I could hear a mixture of delight and indignation.

  My grip was firm but careful, making sure not to snag her silk gown or muss her intricate hair. I carried her across the courtyard, past a bewildered Xiao Kai and Xiao Qi who watched from the doorway with wide, uncomprehending eyes, and out the service gate where her palanquin waited.

  With the same practical efficiency, I carefully stooped and deposited her onto the plush silk cushions inside. She landed with a soft whoosh. She quickly straightened her robes, her cheeks a furious shade of crimson as she refused to look at me.

  “Of all the clumsy, graceless, and… and utterly scholarly things I have ever witnessed!” she huffed at the opposite wall of the palanquin. But I could hear the smile in her voice.

  A grudging smile she could not quite suppress broke into a laugh. She finally turned to me, her eyes a mixture of profound annoyance and sparkling amusement.

  “You are an impossible man, Zhang RuLin.”

  With a sharp rap on the interior wall, she gave the signal to her bearers. The silk curtain dropped, and the palanquin rose smoothly, gliding away into the snowy Chang'an night.

  Returning to the courtyard, I was met by two very different reactions. Xiao Qi was trying, and failing, to hide a grin of pure, boyish amusement behind his hand.

  Xiao Kai, however, simply stood in the doorway, her arms crossed. She watched me with an expression of utter, analytical bafflement, as if trying to solve a Go problem whose logic was completely alien to her. She shook her head once, and gestured to the study.

  I followed her into the warmth of the study, waiting until she had settled herself near the brazier before she spoke. Her tone was carefully neutral, the voice of an aide making an observation about a logistical problem. She paused, choosing her next words with precision. “Do you intend to take her into your household? As a concubine?”

  The question was blunt, practical, and grounded entirely in the logic of her world.

  “No” I explained, making it clear that my offer was not one of possession, but of freedom. I spoke of friendship, of her right to choose her own path, to find someone she might one day fancy. As I spoke, Xiao Kai's analytical expression slowly dissolved, replaced by the same look of profound, bewildered bafflement I had seen on Merchant Zhu's face in the warehouse. The concept I was describing was so alien to the social physics of her world that she was struggling to compute it.

  “You would spend a fortune… to set her free?” she said slowly, as if testing the weight of each impossible word. “And then… simply let her go? To find someone else?”

  She stared at me, her mind clearly searching for the hidden motive, the angle she was missing. The cynical, brutal stories of scholars buying courtesans only to use them as status symbols were the reality she knew. My stated intention was a fairy tale.

  “Men do not do this, Master,” she stated, not as a judgment, but as a simple, observable fact, like saying the sun rises in the east. “Not for a woman who is not their kin or their wife.” Her eyes searched my face, her confusion absolute. “What is your purpose?”

  I began my explanation by carefully pointing out the unexpected. “You too are neither kin to me, nor are you to be my wife either… no?”

  The first sentence strikes her with the force of a gentle but irrefutable blow. She opened her mouth to form a reply, then closed it, the logic of my statement undeniable. Her own presence in my household is a testament to the very principle she was questioning. The analytical confusion in her eyes softened, replaced by a intense focus as she realized I was not just explaining an action; I was explaining myself.

  “You said I was a Mohist, and there are parts I agree with. Must I only love those who are related to me or useful to me?” I asked gently.

  She listened, utterly still, as I wove together the threads of my philosophy.

  “We know that people who choose to aid others without consideration for their interests are already celebrated. The world recognizes them to be good. We call them xiá, and they live as martial examples for others to follow.” I felt a wave of melancholy wash over me. “I can't expect to change the way all the people think. So what I can do is set another example for them to remember. One day, when they remember enough examples, it will become how they think.”

  When I finished, she did not speak for a long time. She looked down at her own hands, then towards the courtyard where the snow was falling, a silent, white curtain on the world.

  “An example…” she repeated my word, her voice a quiet, thoughtful whisper and realisation. “The storybooks are full of such examples. Of righteous heroes who aid the weak and punish the wicked.”

  “My father believed in setting an example, too,” she said, her voice thick with a sorrow that was still raw. “He believed the law could be a righteous brush, that his integrity could inspire others.”

  She looked up at me, and her eyes were ancient, filled with the bitter wisdom of a child who has seen the world's true face.

  “And the system he served broke him for it. His example is now a cautionary tale, a lesson whispered in the capital on the terrible price of honesty.”

  The cynicism in her voice was a palpable thing. But then, she looked at me, truly looked at me, at the man who uses disguises, who commands secret agents, who carries a weapon of thunder, and a new, complex understanding dawned in her expression.

  She said slowly, her mind drawing a crucial distinction. “You are not like him. My father fought with righteousness alone, in the open light of the court. You fight with shadows, with secrets, and with impossible weapons. You use the tools of your enemies against them.”

  She held my gaze, and I realized she finally, truly understood me.

  “Perhaps,” she concluded, her voice a quiet, chilling whisper of acceptance, “that is the only kind of example this world will listen to.”

  “No,” I said quickly with a chuckle. “The world will remember your father too, and someone like Censor Wang. They too show up in the history books of the future.” I smiled sadly. “Me, though? They probably wouldn't record my name, but it'd be enough to leave a folktale.”

  My words, a prophecy of hope from a world she could not imagine, landed with a quiet, profound impact. Xiao Kai's eyes, which had been so full of a cynical, bitter wisdom, suddenly well up with tears.

  “To be remembered by history…” she whispered, her voice thick with emotion. “As a just man… That is all he would have ever wanted. Thank you.”

  The moment of shared, fragile hope hung in the warm study, a stark contrast to the cold, swirling snow outside.

  Then a shadow detached itself from the doorway.

  Steward Feng. He had made no sound, but his presence filled the room with a sudden, chilling intensity. His face was not the usual mask of calm, professional detachment. It was a portrait of sharp, focused, and deeply unsettling inquiry.

  He did not acknowledge Xiao Kai. His obsidian eyes were fixed entirely on me.

  “‘Shadowless Hand' Gao,” he stated, his voice low and cold, the name itself a heavy weight in the room. “I knew him by reputation. For a decade, he was the chief enforcer for the Azure Serpent Society in Jiangnan. His control of inner energy was precise. His hands could shatter stone without leaving a mark. He was not a man to be trifled with.”

  He took a deliberate step into the room. He paused, his eyes narrowing to slits. “But I am told of a sound like thunder that shattered the winter silence, and a weapon that spat fire.”

  He stopped a few feet from me, his gaze pinning me in place.

  “You are a novice in the arts of breath. You were grievously wounded and leaning on a stick.” His voice dropped to a dangerous, silken whisper. “How did you kill a man like Gao?”

  A knot of fear tightened in my gut. I was about to tell this living embodiment of martial mastery that all of his years of training, his entire philosophy of combat, could be rendered obsolete by a cleverly crafted tube of metal. I started by describing black powder. Then I explained how the cane was a pressure vessel, a tube of my strongest steel designed to contain that force and direct it.

  “The fire propels a wave of small steel balls,” I explained, my voice low and steady despite a tremor of unease. “They could travel so fast that the sound of the explosion arrives after they do. There is no time to react, no time to dodge. No amount of cultivated qi can harden a man's flesh enough to stop them.” In truth my weapon didn't quite reach those speeds, but the idea might as well be hyperbole.

  I met his gaze, delivering an honest tactical assessment.

  “But its flaws are significant. It is a single shot. To reload it is a clumsy process, far slower than a crossbow. The noise betrays your position to everyone within a li. And the mechanism is delicate; it requires the finest steel and a master craftsman to create.”

  Steward Feng listened with an absolute, unnerving stillness. His face was a placid mask, but his eyes were burning with a terrifying, focused intensity, his mind dissecting every word, every implication. He was not looking at me as an aide anymore; he was looking at me as a living weapon of an entirely new and unknown design.

  When I finished, he was silent for a full minute.

  He took a step closer, his gaze dropping to the innocuous black cane I was holding.

  “A weapon that requires no strength, no speed, no decades spent cultivating the breath,” he continued, his mind tracing the tactical ramifications with horrifying speed. “A weapon a common soldier could use to kill a master.” He looked back up at me. “But, as you say, it is loud. And it is useless after the first strike. A single clap of thunder, and then silence.”

  He fell silent again, a new, complex understanding dawning in his expression.

  “It is an ugly thing,” he said, his voice now a soft, dangerous murmur. “The tool of an assassin, not the blade of a warrior. A device for killing without honor, without artistry, without skill.”

  He held my gaze, and a cold smile, the most terrifying expression I have ever seen, touched his lips.

  “It is… perfect.”

  He looked from me to the cane and back again.

  “The Master,” he said, his voice a silken promise, “will be very interested to hear of this.”
