Xu Yinyin

Two hours later, when Yun Zishan returned to the Interrogation Room, a female disciple half a head shorter than her followed close behind.

She was none other than Yun Zishan's only personal disciple, Xu Yinyin. When they pushed open the iron door, the sight before them made both of them pause in surprise.

All the renovations in the Interrogation Room had been completed, and the place looked completely different.

The walls were covered in pale gray Acoustic Foam, and dark Anti-Slip Mats covered the floor. Even the ceiling had been renovated, with several Battery-Powered Light Panels embedded in it, casting a soft white glow. The faint scent of air freshener filled the room, completely masking the stench of blood that had lingered before.

Yun Zishan stepped inside, and Xu Yinyin followed close behind. Her lively eyes glimmered as she curiously surveyed the unusual room.

Xu Yinyin was Yun Zishan's only personal disciple, a unique position within the Law Enforcement Hall. By comparison, Qiao Bin and the others might have joined earlier, but they were merely registered disciples of the hall. In daily life, they could only respectfully address Yun Zishan as "Hall Master," never "Master."

"Greetings, Senior Disciple Qiao!" Xu Yinyin said, immediately giving Qiao Bin a proper salute. "I heard you found a way to make that Undercover Agent talk, so I begged Master to bring me along and see it for myself."

Qiao Bin hurried forward and politely raised a hand as if to help her up, a warm smile on his face. "You're too courteous, junior sister. I've told you before, there's no need for such formalities between us. You're always welcome here."

Xu Yinyin flashed her little tiger teeth and playfully blinked. "Rules are rules! Master always says they must be followed at all times."

As she spoke, her attention had already been drawn to all the strange new objects in the room. Her lively eyes darted about curiously before settling on a black, square-shaped object in front of the interrogation table.

"Senior Brother, I've been to Zhaoyu Tower several times. How did it change so much today?" She pointed at the black square. "What is that? I've never seen anything like it."

At dusk, Qiao Bin had been unable to answer Yun Zishan when she asked about the equipment because he hadn't memorized the details. That evening, he had spent over an hour committing to memory every piece of equipment Yang Ning had introduced, along with its purpose. Now he answered calmly, "This is called a Microphone. With it, we can speak to someone in the room on the other side of this wall."

Xu Yinyin took a step forward, eager to get a closer look, but Yun Zishan's cool voice cut in at just the right moment. "Yinyin."

The girl's raised foot hung in midair. Reluctantly, she drew it back and pouted as she murmured, "Yes, Master."

Yun Zishan was now standing before the One-Way Glass. Through the transparent barrier, they could clearly see the scene on the other side: the Undercover Agent, shackled to a specially made chair, was still unconscious, while Yang Ning stood nearby, intently fiddling with a flat, glowing object.

As Yang Ning swiped across the Tablet Computer in his hands, he thought, The Electronic Products from the System Mall really are convenient. They can even connect to a dedicated Wi-Fi network. It's just that two Spirit Stones a month for internet access really hurts. That's as much as I make from selling a stick of incense. As he thought, he quickly checked the preset program.

Once everything was ready, he took a Fitness Tracker from his pocket and carefully fastened it around the Undercover Agent's wrist. Then he took a pair of VR Goggles and Noise-Canceling Headphones from a nearby box and carefully put them on the still-unconscious man.

To everyone outside the One-Way Glass, everything he did involved strange devices they had never heard of before.

Yun Zishan furrowed her delicate brows slightly. Qiao Bin's palms were slick with nervous sweat, while Xu Yinyin's eyes sparkled with excitement, her interest in everything before her plain to see.

"Hall Master, may we begin?" Qiao Bin asked, cupping his hands toward Yun Zishan.

Seeing Yun Zishan give a slight nod, Qiao Bin recalled the training Yang Ning had just given him. He reached out, pressed the red button nearby, and tapped the Microphone.

"Hello—hello—can you hear me?"

After the Interrogation Room had been renovated, the person inside could hear those outside through the speakers, but thanks to the Acoustic Foam, those outside couldn't hear anything from within.

Yang Ning walked up to the One-Way Glass and gave a thumbs-up through it.

And directly opposite Yang Ning, on the other side of the One-Way Glass, was Yun Zishan!

Yun Zishan was tall, only a little shorter than Yang Ning. As Yang Ning stared at the glass, his eyes happened to meet hers.

In Xu Yinyin's eyes, the two figures overlapped through the glass. She had no idea it was One-Way Glass, and was so startled that she clapped a hand over her mouth, not daring to move.

Xu Yinyin's eyes went round as saucers. Her gaze shifted back and forth between her Master and Yang Ning behind the glass. Standing behind and to the side, she couldn't make out her Master's expression, so she focused all her attention on the unfamiliar man behind the glass.

She couldn't help but start shipping them. He really is a handsome one, with a roguish glint in his eyes that's hard to describe—quite captivating. I wonder which sect he's from... His clothes don't look like those of a sect disciple... Still, no matter how striking he is, he's not good enough for my Master...
