In the days that followed, Cai Zhao kept herself quietly busy.
She haunted Qingjingzhai from morning to dusk, watching the pigeon cage the way a farmer watches the sky before rain. Master Juexing's gift of carrier pigeons had seemed like a strange kindness at the time. Now she was grateful for every one of them.
The night after news broke of the faction attacks, she sat down and wrote.
Chang Ning crouched beside her, grinding ink and trimming paper, stealing glances at each letter as she sealed it. What he read left him briefly speechless.
The first letter went to Peqiong Villa.
She asked after Zhou Zhizhen and Zhou Zhixian by name, hoped their wounds were nothing bone-deep, and told them to raid Luoying Valley's medicine stores without guilt — she'd attached two tubes of gold sore ointment to the pigeon's leg already. She would have sent the entire medicine chest Ning Xiaofeng left her if she didn't fear the bird would drop out of the sky from the weight.
Chang Ning set down the ink stone. "Is it that you love the Zhous, and therefore love whoever they love? Or is it that Zhou Yuqi loves them so much you can't help but love him too?"
Cai Zhao picked up the ink stone. "Keep talking and I'll grind this across your face."
The second letter went to Changchun Temple.
She addressed Master Fakong with the brisk affection of someone scolding a favorite uncle. Burns are no joke on old skin, she wrote. She enclosed two tubes of burn cream — Luoying Valley's formula, strong enough to restore a dried shrimp, she claimed — and copied out a recipe for a lung-clearing decoction to flush out the smoke he'd swallowed. If his lungs gave out and he couldn't recite sutras, who would knock the wooden fish?
"Did Luoying Valley have a grudge with Master Fakong?" Chang Ning asked.
"No one has a grudge with anyone. The old monk is perfectly fine."
"So Zhaozhao is just... comforting him."
"Naturally."
Chang Ning stared at the ceiling. "May Amitabha Buddha bless me with a fast trip up Shinobi Mountain."
The third letter was meant for Ning Xiaofeng, but she crumpled it before it was half-written. Without her own blood and effort, even a carrier pigeon couldn't find the entrance to Ningjiawu Fort.
She considered writing to Master Jingyuan at the Hanging Temple instead, then pictured her great-aunt's thousand-year frozen expression and her brush went still. She couldn't squeeze out a single word. In the end she just tied two tubes of ointment to an outgoing pigeon and called it sentiment.
After the letters were sent, Cai Zhao haunted the cage for two things: replies, and the return of Cai Pingchun.
While she waited, the clan was quietly falling apart around Qi Yunke.
Everyone had assumed his injuries were minor — purge the remaining poison, rest a few weeks, done. Then one morning he vomited black blood and didn't get back up. He lay in his tent drifting in and out, his face the color of old wax.
Zeng Lou became a blur of motion — managing clan affairs, hunting for medicine, standing guard at Qi Yunke's bedside. He had no time to breathe, let alone talk to Cai Zhao.
When Qi Yunke finally surfaced into consciousness, his disciples filed in to see him. Song Yuzhi came too, leaning on someone's arm. Lei Xiuming knelt beside the bed with two fingers at his wrist, his frown deepening the longer he held the pulse.
"Why did the toxicity spike so suddenly?" he muttered, more to himself than anyone. "The pressure's dropping now, but this back-and-forth makes no sense."
Qi Yunke caught it and smiled faintly from the pillow. "I was careless with my breathing exercises. Pushed the residual poison the wrong direction. It's nothing Lei-daifu's hands can't handle — I just need rest."
Lei Xiuming said nothing more, though his frown didn't ease.
Yin Sulian, faced with her husband hovering near death, seemed to calculate briefly between the dignity of a sect leader's wife and something that might actually count as virtue. Virtue won — barely. She appeared at the bedside with tea, fussed over the blankets, spoke softly. Her disciples watched with undisguised unease.
Qi Yunke said something under his breath, cold-faced. She left in a fury.
Cai Zhao watched the whole performance, turned to go, and found Song Yuzhi standing alone behind a corridor pillar. Something in his stillness caught her eye. A thought flickered at the edge of her mind — and she let it go. She had a pigeon cage to watch.
The replies came back one by one over the following days.
Peqiong Villa had taken real losses. Few escaped the ambush cleanly. The four Zhous were all alive and recovering, but the families of the disciples who hadn't made it home were another matter — widows, elderly mothers, people with no one left. Zhou Zhizhen had already committed to providing for them all.
Changchun Temple came back with better news overall — flesh wounds, most of them, nothing that wouldn't heal. But Master Fakong was struggling in a way medicine couldn't fix. He was old, and his elder brother Fahai, who had walked every road beside him for decades, was gone. The surprise attack on the return journey had landed on a man already quietly grieving. He was not well.
Xuankong Temple sent a long stack of sermons. Cai Zhao didn't read them.
She was still setting down Master Jingyuan's warning letter when Furong appeared at the door.
Cai Pingchun had finally come back.
He'd reached Qingque Town after dark and chosen not to climb Jiuli Mountain at night. He'd taken a room at the Yue Inn — a name of plain confidence, the most expensive lodging in town for reasons no one had ever satisfactorily explained.
Walking the cobblestone lanes toward it, Cai Zhao noticed the crowd.
"The festival ended days ago," she said, watching the press of bodies around them. "Why are there still so many people?"
Chang Ning scanned the faces. "They all look like they're working. I can't tell at what."
Neither of them knew Qingque Town well enough to know whether this was normal. They let it pass.
The inn's shopkeeper stood behind his counter like a man who had outlived his interest in being alive. He glanced up when they entered, raised his eyelids just enough to point at the Tianzi Room No. 1 placard, and said nothing. A half-dead attendant materialized to lead the way.
Chang Ning was delighted. "I'm certain now. You have a history with this man."
"When we first came to Jiuli Mountain, our family stayed here. Just us — the only guests in the whole place — and he charged us like we were filling every room, with a face like we'd insulted his ancestors." Cai Zhao sighed. "So I gave him a small piece of advice."
"What advice?"
"I told him he might do better running a tollbooth."
Chang Ning laughed the whole way up the stairs.
Half a month of hard travel had taken its toll. Cai Zhao saw the new lines around her father's eyes, the way his cheekbones had sharpened, the darker weathering of his skin, and felt a fierce and immediate urge to light a stove.
Cai Pingchun looked her over in return. He found a girl who had grown into something steadier. Her eyes were quieter. Her bearing had shifted.
He smiled. "Qingque Sect's cooks clearly take care of their guests. Look at you — fed well, rested well. I go out to suffer for half a month and come back to find you've only grown more sensible."
Then he looked at Chang Ning.
The young man's face still carried the marks of the poison, but his composure was absolute. Eyes clear, posture easy, the kind of self-possession that takes years to build.
"Chang's nephew — is the toxin healing?"
Chang Ning bowed. "There's still some residue."
Cai Pingchun's brow moved slightly. He said nothing.
Cai Zhao noted with private amusement that Chang Ning hadn't said a single strange thing since crossing the threshold. He was elegant. Measured. He looked more the part of a ducal heir than Song Yuzhi ever had.
Father and daughter talked for a long time, covering everything from small comforts to larger trouble. Eventually it came around to the attacks — the Qingque Sect invasion, the ambushes on the other factions.
Cai Zhao voiced what had been sitting at the back of her mind. "Chang Ning said the demon cult hasn't grown much stronger than before. So why were they so effective this time?"
Cai Pingchun said, "There are all kinds of ugly people in this world. You can't always trace the logic of what they're after. Stop trying to reason it out now — once everyone has recovered and your master takes the lead, we'll march straight to Netherworld Huangdao Road and find a good spot to wait for Nie Hengcheng. He's been quiet for years. If he wants to start again, the six sects of Beichen will be ready to receive him."
The calm in his voice and the weight behind it occupied very different spaces.
Cai Zhao felt it settle in her chest.
Chang Ning, who had been listening quietly, stepped forward and bowed — arms folded, back straight, every line of him correct.
"Uncle Cai. My nephew asks with respect — did you find anything at Changjiawu Fort?"
Cai Pingchun considered. "The fort is rubble now. I searched the ruins, then walked the mountain's perimeter. Everything points to the demon cult."
Cai Zhao: "Dad. Brother Chang said that two weeks ago."
Cai Pingchun ruffled her hair. "What does a silly girl know."
He turned back to Chang Ning. "I checked because I wondered whether someone had used the demon cult as cover — committed the act themselves and planted the signs. But I checked everything. The marks at the base of the mountain. The hidden indicators pressed into the grass. The stakes driven in around the ambush points. Even the patterns of destruction in the ruins themselves. All of it — unmistakably Lu Chengnan's method. The Tiangang Disha Camp, same as always."
Cai Zhao's mind moved quickly. "Lu — could that be one of Nie Hengcheng's four great disciples? Zhao, Chen, Han, Lu?"
"The fourth. He kept no record of evil that anyone could point to openly, which made him respected in the martial world — but he was lethal in every direction. Internal cultivation, mechanical formations, terrain reading, tracking, poison, assassination. He trained the entire Tiangang Disha Camp himself, in his own methods."
Cai Zhao went cold. "This man destroyed the Chang family."
"No. He's been dead longer than Nie Hengcheng." Cai Pingchun's expression shifted to something dry. "When we were young and tracked down one of the camp's sub-leaders, we found them in full mourning dress — hemp cloth, tears running, burning paper offerings. They were holding a memorial for Lu Chengnan."
Cai Zhao blinked. "The demon cult has people who grieve."
Her father's mouth curved. "Demon cult members are still people. Seven emotions, six desires — all present. Lu Chengnan had real standing among the younger members. How he died, no one agrees on. Accident. A trap set by our six sects. A jealous senior brother. Take your pick."
He paused. "What's certain is that when Lu Chengnan died, Nie Hengcheng lost something he never fully replaced. If he'd lived, your great-aunt couldn't have found Nie Hengcheng as exposed as she did. She couldn't have challenged him when he was already isolated."
"He sounds formidable," Cai Zhao said quietly.
Chang Ning looked at her sidelong and said nothing.
"Even now, the camp still trains on Lu Chengnan's methods. I can read it in everything they left behind at Changjiawu Fort." Cai Pingchun continued. "In recent years, the Siqi Sect under Guangtian has been aggressive — reaching further, building power. For the demon cult to feel threatened enough to hit back, that part makes sense."
He shook his head. "What I still don't understand is why the Chang family had to be destroyed. Your father stepped away from the martial world after Nie Hengcheng fell. He had no involvement."
Chang Ning was quiet.
Cai Zhao caught the name Guangtian and immediately thought of Song Yuzhi. "Dad — my third senior brother. Song Yuzhi, the son of Songmen's sect leader. He was hit with Nether Cold Qi. He's barely holding his cultivation together. Is there any treatment?"
Chang Ning drew a slow breath and worked very hard to continue looking serene, composed, humble, and upright.
He was furious.
"Nether Cold Qi." Cai Pingchun frowned, thinking. "I don't know the cure offhand. But... there should be one."
Cai Zhao's eyes sharpened. "How?"
"Your aunt had a brother. Shi Tieqiao — the second of the Shi brothers."
Chang Ning: "The second Shi brother?"
"That's him. He took a strike of cold Nether force. Your aunt found a way to bring him back, though I don't know the method."
"So who does know?" Cai Zhao pressed.
Chang Ning took the opening before she could dig further. "Those who practice Nether arts aren't many. Among them, some will know the cure."
Then, smoothly: "My nephew has another question, if Uncle Cai will permit."
"Go ahead."
"Before Wu Gang died, he said that Old Sect Leader Yin refused to let Elder Kaiyang go — used him to replace Wu Yuanying, to force something out of him. Does Uncle Cai know what that was about?"
Cai Zhao straightened. She remembered this too.
"I always wondered," she murmured. "Why not just ask Master directly. He must have known what Old Sect Leader Yin was after."
Chang Ning offered a carefully neutral expression. "My nephew suspected it might not reflect well on anyone, which would make it difficult for Sect Leader Qi to speak of openly."
Cai Pingchun nodded slowly. "Chang's nephew is right. This business is not glorious."
Cai Zhao stared. "Tell us."
For a long stretch of years before Nie Hengcheng fell, the two sides were matched. Not equal in every sense, but close enough that neither dared strike first.
The three Qingfeng elders were in the full force of their ability. The two great heroes each had their own weight. Guangtian Gate and Siqi Gate within Peqiong Villa were deep with talent. Luoying Valley had Cai Changfeng holding its face. And from the younger generation, names like Zhou Zhizhen, Song Shijun, and Wu Yuanying were rising fast — to say nothing of rarer talents like Cai Pingshu.
The standoff held for years.
Then it broke.
"Old Sect Leader Yin noticed something wrong," Cai Pingchun said. "He'd fought Nie Hengcheng before — it wasn't a clean win on either side, but Yin had always been able to stand his ground. When they met again, Nie Hengcheng's power had jumped to a different level entirely."
"First encounter — Old Sect Leader Yin barely escaped intact."
"Second encounter — he couldn't last a hundred moves."
"Third encounter — if Cheng Hao and Wang Dingchuan hadn't thrown themselves into the gap at the cost of their lives, Old Sect Leader Yin would have died there."
Cai Zhao's mouth had fallen open. "How does Dad know all this? Even if he lost badly, Old Sect Leader Yin wouldn't go around talking about it."
"One of Wang Dingchuan's disciples told your aunt," Cai Pingchun said simply. "She'd saved his life."
Chang Ning absorbed this in silence. Then, slowly: "If Nie Hengcheng's power jumped that dramatically... the balance of force between the two sides would have collapsed entirely."
He let it settle before continuing. "So that's why he attacked. He saw he couldn't be stopped. After that, he kept pushing — giving his followers room to run rampant — trying to eliminate the six sects and take the world."
Cai Pingchun inclined his head. "Old Sect Leader Yin's mind was sharp. He concluded that Nie Hengcheng must have encountered something — some profound technique, a chance inheritance. And he wanted to know what."
"So he took Elder Kaiyang." Cai Zhao hit her palms together. "He used him as leverage to force Nie Hengcheng to give up his secret."
"Kaiyang and Yaoguang were both personally recruited by Nie Hengcheng — they had been his confidants for over a decade. If they didn't know, no one did."
"Did anything come out of it?" Cai Zhao leaned forward.
Chang Ning's expression remained smooth and sorrowful and entirely correct. "If it had, your great-aunt wouldn't have needed to risk her life going after Nie Hengcheng herself."
Cai Pingchun smiled. "My nephew reasons well."
Cai Zhao cut a sideways look at Chang Ning. Three words sat behind her eyes, plain as painted characters.
Such a performer.
