Cao Er rushed to Ye Yu's lifeless body and took a glance. She stomped her foot, gritted her teeth, "Who could have dared to steal my senior sister's Lu Mo Li Hun Caih? I'm just lucky enough to find out in time or else Master Ye Yu's Leng Yan Jingang Lun would have been taken by him too!"

She suddenly remembered something and picked up the cold jade disc from where Ye Yu had died. With both hands, she offered it to Li Yundong: "Master of the sect, this is my sister-in-arms Ye Yu's treasure - please accept it."

Li Yundong frowned but didn't reach out immediately. He asked, "Why not you keep your sister's belongings then?"

Cao Er explained, "This Leng Yan Jingang Lun was left by our former master to Master Ye Yu. With both of them gone now, naturally belongs to the current master - you."

As Li Yundong took it in his hands, a heavy weight settled on him. The artifact resembled a crescent moon with one side silver etched with elegant flying Bodhisattvas and another golden side carved with fierce Diamond Recluse warriors.

Running his fingers along its surface sent an icy chill through his skin, especially when he touched the blade edge - the air itself seemed to freeze at the razor-sharpness of it.

"This artifact is strange," Li Yundong suddenly remarked as his finger brushed against the serrated inner blade. "Why are these teeth on the inside?"

Cao Er smiled knowingly, "The outer rim also has teeth but they're so fine you can barely see them with your eyes. When spinning at full speed, this Leng Yan Jingang Lun could slice through anything. The inner teeth are more for parrying enemy weapons."

Li Yundong nodded and tried to store it away but paused, scratching his head: "I already carry around my Qibao Tongling Shuan everywhere. If I'm constantly carrying this too, won't the police arrest me?"

Cao Er laughed, "Are you afraid of worldly police as a great sect master?"

Li Yundong spread out his hands, "Shouldn't we follow worldly rules if we're practicing in the mortal realm?"

Cao Er produced two tiny rainbow-colored silksacks from her side: "This is a Bai Bao Dai - it looks small but contains a miniature world. You can store anything inside... though there's one drawback."

She continued, "Once you put things in it, you can't take them out without destroying the sack itself."

Holding the bag up to him, she said, "Since it's inconvenient for you..."

Li Yundong refused, "It's your treasure. What if I need to use my during a battle and destroy this bag of yours?"

Cao Er smiled warmly, "If not for you saving us from death, wouldn't all our treasures already be someone else's? You've saved the whole Hu Chan Sect - refusing would deeply hurt us."

Li Yundong accepted it with an embarrassed grin: "I don't even know how to use it!"

Her eyes widened in disbelief.

"I've only been cultivating for less than half a year," he admitted.

All present Fox Cult disciples stared at him in shock, their round eyes like dinner plates. Cao Er giggled, "You mean you became master in six months? Are you joking?"

Li Yundong smiled, "I met Su Chan several months ago and started cultivating since then."

Cao Er gasped, "A half-year cultivation reaching such heights... You're the greatest cultivator through all of history!"

As he joked about being clueless with the Bai Bao Dai, Cao Er demonstrated by tapping its opening. A brilliant rainbow light spilled out.

"Put your inside," she instructed as Li Yundong placed both his Qibao Tongling Shuan and Leng Yan Jingang Lun into it.

At her next tap, the bag sealed itself shut with a flash of light.

"Now just tear open to retrieve anything you need," Cao Er explained.

Li Yundong fastened one at his waist for convenience and tucked another away secretly: "I'll head to Dong Wu City now."

Cao Er hesitated, "Do you know where Su Chan is exactly?"

He stopped short, frowning, "The former master didn't have time to say before dying!"

"How will you find her in a huge city?" she asked.

"I don't know. Maybe post missing posters?" he sighed.

"No! We cultivators must remain discreet even when practicing among mortals," Cao Er warned.

"Then I'll just search every place one by one," Li Yundong resigned himself to the task.

Cao Er smiled, "Awhile ago, Aowushuang had a hideout in Dong Wu City - Su Chan might still be there."

"Where?" he asked eagerly.

"Dong Wu's Qili Shantang," she answered.

"What's that?" he asked again.

"A scenic spot named for its seven-li length," Cao Er explained as Li Yundong left quickly down the mountain.

Watching him depart, Cao Er mused: Fortunate indeed - when our sect teetered on the brink of extinction, Heaven blessed us with such a young and capable master!

Li Yundong hailed a taxi at base of Tianlong Mountain. After over an hour's drive, he entered Dong Wu City's ancient capital.

The city retained its old-world charm despite modern vehicles zipping through streets lined with contemporary shops. Even bus stops bore traditional eaves and intricate carvings.

As the driver dropped him off near Qili Shantang's stone arch bridge, Li Yundong stared at the four gilded characters - "Qili Shantang" - painted on a red gate tower. His heart pounded as he stepped into the historic district with its whitewashed walls and black-tiled roofs.

Passing through an old wooden sliding door, he saw shopkeepers waving colorful flags advertising their wares. Young girls in traditional attire called out to customers from roadside stalls, their eyes bright and voices melodic.

At a food stall where diners munched on sesame cakes and noodles, Li Yundong asked the server about Su Chan - only to be met with rapid local dialect he couldn't understand until she repeated herself in Mandarin: "I don't know. Ask elsewhere."

Disappointed but undeterred, he continued down the cobbled street past pearl shops where a girl's ponytail reminded him of Su Chan for an instant before proving to be just another passerby.

At a noodle house nearby, two monks wearing brown monastic robes whispered about "purifying a demon." Li Yundong's heart froze - had someone captured his beloved?

Slipping into the restaurant himself, he ordered noodles and watched from a corner as the monks paid their bill and hurried away. He followed closely behind, ignoring his untouched meal until the server called out to him.

Leaving a generous tip without waiting for change, Li Yundong continued the pursuit through the ancient streets of Qili Shantang.
