Too many female prisoners, a special forces soldier transmigrates and marries wildly.

The pimp's smile froze for a moment, then he became even more ingratiating:

"Sir, you have excellent hearing! Miss Yunshang is indeed here. However, she is a quiet person and rarely sees outsiders. She usually only plays music for a few close esteemed guests. Perhaps... you could go upstairs first, have some wine, and I'll go ask her how she's feeling today?"

Lin Feng hummed in agreement through his nose.

The pimp quickly led him up to the second floor and into a secluded room at the end of the corridor.

The guards put down the wine jars and silently retreated into the shadows outside the door.

The pimp poured a cup of wine with great courtesy: "Please have a seat, sir. I'll go and invite Miss Yunshang right away." With that, he bowed and left, gently closing the door behind him.

About the time it takes for an incense stick to burn, very light footsteps came from outside the door and stopped at the entrance.

Then came the pimp's fawning voice: "Miss Yunshang, this is the song that this gentleman wants to hear."

The door was gently pushed open. A woman carrying a pipa walked in with her head bowed.

She wore a light blue ruqun (a type of traditional Chinese dress) with a pale white half-sleeved outer garment, which accentuated her slender figure. Her face was lightly powdered, and her features were exquisitely beautiful; she was indeed a beauty, but without a trace of vulgarity, instead exuding a scholarly, aloof charm. Especially her eyes, when she looked up at people, were calm and unfathomable.

"Yunshang greets this gentleman." Her voice, like the person herself, was clear and calm, without much variation.

Holding her pipa, she sat down on an embroidered stool a few steps from the table, not even glancing at Lin Feng. "What tune would you like to hear, sir?"

Lin Feng leaned back in his chair, his gaze falling on her face before sliding to the pipa in her arms.

"Whatever," he said.

Yunshang nodded slightly and said no more.

The clear, melodious sound of a pipa filled the quiet room.

Lin Feng listened quietly, his fingers slowly clenching under the table. This melody… he had heard a similar tune before. In the "Wall of Sighs" of the Devil City, the wind whistled through the caves, producing this strange sound—a mournful wail tinged with sharp, angular lines!

This woman is definitely connected to the Sand Fox and something deep within the Flowing Sand Sea!

As the music ended, the lingering notes drifted away in the sandalwood incense.

Yunshang put down her pipa, looked up at Lin Feng, her gaze still calm: "What do you think, Master?"

"Not bad." He fiddled with the empty wine glass, but his gaze remained fixed on Yunshang's face.

"The melody is too cold; it makes me feel suffocated. Do you have anything more lively? Like... the kind of howling that the Di Rong people do when they drink?"

Something flashed across Yunshang's eyes very quickly, so quickly that it was impossible to catch it.

"You jest, sir. I only know these lowly ancient tunes, the sounds of the barbarians, and I have never learned them."

Yunshang looked at Lin Feng quietly for a moment, then suddenly stood up, holding her pipa and slightly curtsied: "I am a little tired today, and I am afraid I will spoil your mood. If you don't mind, I will play for you another day."

This is to see the guests off.

Lin Feng didn't insist on keeping him. He nodded, took out a silver ingot from his pocket, and placed it on the table.

He turned around, opened the door, and strode out. The guards outside immediately followed.

The footsteps disappeared at the top of the stairs.

Inside the private room, Yunshang stood alone, staring at the silver ingot on the table, then slowly looked up at the dark night sky outside the window.

She put down her pipa, walked to the window, to the spot where Lin Feng had just stood, and gently pressed a button in a very hidden corner of the window frame.

A small piece of wood sprang up, revealing a hole the size of a grain of rice underneath. She gently blew three breaths into the hole in a specific rhythm.

A moment later, a few short, sharp hisses, like night owls fighting, came from the back alley downstairs, and then silence returned.

Yunshang withdrew her hand and pressed the wood chips back into place.

She walked to the painting of withered lotus flowers on the wall and pressed her finger on a certain spot on the scroll.

With a soft "click," a section of the wall next to the scroll slid open inward, revealing a narrow, hidden doorway just wide enough for one person to pass through. The interior was dark and deep, with stairs leading downwards.

Without the slightest hesitation, she picked up her pipa and slipped inside. The hidden door closed silently behind her, and the walls returned to normal, as if nothing had happened.

Only the cold silver ingot lay quietly on the table, reflecting the flickering candlelight.

downstairs.

Yan Qing emerged from the shadows and whispered, "General, how is it?"

"It's her." Lin Feng's voice was icy.

"At least, it's a lead. There's a hidden door inside; she went in. Have your men keep an eye on all the exits of this building, especially the back path used for transporting toilet paper and firewood. She might leave, or she might just be delivering a message. Also," he paused.

"Investigate the owner behind this building, and that pimp. Hurry."

"yes!"

Lin Feng turned around and took one last look at the window on the second floor of "Dark Fragrance Pavilion" that was lit but now empty.

The fox's tail was finally peeking out a little. Even though it was just a little, it was enough to follow the trail of its tail.

In the study of the Marshal's Mansion, the candlelight flickered.

Zhao Dechang stood by the window with his hands behind his back, listening to Lin Feng's report without turning around.

"So you think that woman is inextricably linked to Sand Fox and Prince Jing?"

"Yes," Lin Feng replied.

"Where's the secret door? Are you sure?"

"Our informant saw it with his own eyes. Shortly after Yunshang returned to her room, there was a slight noise from the wall next to the painting of withered lotus flowers, and then her presence disappeared from the room. The wall is a solid brick wall with no hidden layers, only a secret door. A quarter of an hour later, her presence reappeared in the room, slightly moved. She must have gone through the secret door and then returned," Yan Qing added in a low voice.

Zhao Dechang walked back to his desk and sat down.

"Who owns the Dark Fragrance Pavilion?"

"The apparent owner is a silk merchant from Suzhou surnamed Hu, with a clean background. But Mr. Hu only comes to Shuofeng once or twice a year. The one actually in charge of the brothel is a local woman surnamed Liu, who has been in the brothel scene for over thirty years. She's very shrewd and there are no obvious flaws yet. The pimp is a distant nephew of Liu, greedy, gossipy, and timid. Perhaps we can pry him out." Yan Qing spoke very quickly.

"Has the infiltration of the Di Rong centurion been confirmed?"

"Confirmed. It's a centurion from the 'Bald Wolf' tribe named Harbala. Half a month ago, he disguised himself as a fur merchant and entered the city. That night, he stayed at the Dark Fragrance Pavilion and specifically requested Yunshang to accompany him. He left before dawn the next day, and his whereabouts were kept secret. Our people tried to track him down, but lost track of him thirty miles outside the city. We suspect there was someone helping him."

Zhao Dechang was silent for a moment, then turned his gaze to Lin Feng:

"What are you planning to do next? After your investigation, that woman will surely be on guard. She may have moved behind the hidden door, or she may have increased her security."
