A rollback after death? Then let them offer their loyalty!

I completely agree with Chapter 57.

……

Almost the instant Lin Yu had this thought, he had already returned to a point in time shortly after he and Qin Shuang had "finished their business".

An ambiguous atmosphere still lingered in the apartment. Lin Yu immediately spotted Qin Shuang kneeling beside the sofa.

Qin Shuang stood with her back to the door, her shoulders slightly shrugged, holding a glass in her hand, the rim of the glass directly at Qin Xue's lips on the sofa.

Qin Xue lay on her side, her throat moving unconsciously, making soft swallowing sounds.

Hearing the door open, Qin Shuang turned around abruptly.

Upon seeing that it was Lin Yu, the panic on her face instantly faded, replaced by a flush that was a mixture of shame and excitement.

"Brother Lin Yu...why are you back?" Qin Shuang's voice was a little hoarse.

Instead of putting down the cup, she raised her wrist, letting the last drop of liquid slide into Qin Xue's mouth.

Qin Xue frowned slightly, then stuck out her tongue and licked the corner of her moist lips.

Lin Yu closed the door and walked in.

"I came back to get something." His gaze fell on the cup in Qin Shuang's hand: "What are you doing?"

Qin Shuang stood up, walked barefoot on the carpet to Lin Yu.

She raised her head, her eyes alluring and captivating.

"Let me drink some water, sister," she said softly, holding the empty cup up to Lin Yu's eyes and waving it around. "Look, it's all gone."

Lin Yu took the cup and placed it on the cabinet next to him.

Qin Shuang immediately pressed herself against him, wrapping her arms around his waist.

"Brother Lin Yu..." She buried her face in Lin Yu's chest, her voice muffled, "I still feel it's not enough."

"What's not enough?"

"Not enough for my sister to remember." Qin Shuang raised her head, a stubborn glint in her eyes:

"Just drinking it... is too easy on my sister. She won't know anything. When she wakes up, she'll just think it was a strange dream."

As Qin Shuang spoke, she took Lin Yu's hand and led him to the sofa.

Qin Xue was still unconscious, breathing evenly, her lips moist and soft from the "water" she had just been exposed to.

"Look at her." Qin Shuang crouched down, her fingers gently tracing Qin Xue's cheek:

"Always so clean, so perfect..."

She turned to look at Lin Yu, her eyes welling up with tears: "Lin Yu, can you give me a little more... please?"

"Right now, right here, I want to feed her myself!"

Lin Yu crossed his arms and looked quietly at Qin Shuang, then nodded.

Qin Shuang's breathing quickened as she reached out to unbuckle Lin Yu's belt, her movements trembling with urgency.

"Hurry up..." Her voice trembled, whether from excitement or something else, it was hard to tell.

"Before my sister wakes up, I want to let her experience the most direct..."

Qin Shuang knelt down as she spoke.

Twenty minutes later.

Qin Shuang gripped Lin Yu tightly with one hand and used the other to lift the back of Qin Xue's head, tilting her face slightly upwards.

"Sister, are you thirsty too? Here's some water for you~" Qin Xue blinked and then put a straw into Qin Xue's mouth.

"Hmm..."

Qin Xue's throat moved, and she instinctively sucked.

The sound of swallowing could be clearly heard in the quiet living room.

Qin Shuang opened her eyes wide, her body trembling slightly, as she witnessed a side of her proud older sister she had never seen before.

A few dozen seconds later, Qin Shuang released Qin Xue and took a step back.

Qin Xue slumped on the sofa, her lips moist and swollen, her chest heaving as she unconsciously murmured:

"Water...more..."

Qin Shuang looked at Lin Yu, a bright yet eerie smile blooming on her face.

"She likes it~"

Lin Yu didn't say anything, but walked to the single sofa and sat down.

Qin Shuang snuggled up to him and curled up at his feet, like a little rascal.

"Brother Lin Yu~" She pressed her face against Lin Yu's knee: "Do you think my sister will remember when she wakes up?"

"Won't."

"That's good." Qin Shuang chuckled. "This is a secret that belongs only to the two of us."

She paused, her voice lowering:

"Actually... I know this is wrong, but every time I see my sister's calm and always-right demeanor, I can't help but want to... dirty her, ruin her~"

Do you think I'm absolutely awful? A complete bad girl?

Lin Yu placed his hand on Qin Shuang's hair and gently ruffled it: "Keep it this way, I like you just the way you are."

Qin Shuang comfortably squinted her eyes: "Lin Yu, what did you come back for?"

"It's nothing," Lin Yu said. "I have something to tell Qin Xue when she wakes up."

"What is it?"

"About the wall."

Qin Shuang's body stiffened slightly.

She looked up, the languid look on her face vanishing: "A wall?"

"Hmm." Lin Yu looked at Qin Xue, who was still unconscious on the sofa.

"I found signs of damage on the protective wall," Lin Yu said calmly.

Qin Shuang's face turned pale.

Her parents died outside the wall. During a routine inspection, they discovered that someone had damaged the wall, and then they were attacked by unknown forces. Their bodies were not found until two days later, and they were barely recognizable as human.

From then on, "wall" became the most sensitive word in Qin Shuang's heart.

"Who?" Qin Shuang's voice turned cold.

"The investigation is still ongoing, but I need your help. We need to see the person who damaged the wall with our own eyes, and then we can report this to the authorities together."

Qin Shuang nodded.

If someone is really thinking about building a wall, that must be the highest priority.

I agree.

I believe my sister will agree too; she hates those who try to build walls even more than I do.

Lin Yu nodded, then stopped talking, his hand still gently stroking Qin Shuang.

The only sound in the living room was Qin Xue's even breathing.

Half an hour later, Qin Xue's eyelashes trembled. She opened her eyes, and her vision was blurred for a few seconds before it focused.

The first thing you see is the ceiling.

Next up was Lin Yu, sitting on a single sofa, and Qin Shuang, curled up at his feet.

Qin Xue propped herself up, feeling a wave of dizziness.

"I..."

"Sister, you're awake!" Qin Shuang immediately stood up and ran to the sofa to support Qin Xue.

"How are you feeling? Is there anything else that's bothering you?"

Qin Xue rubbed her temples, and her memories slowly returned.

Sewers, frost worms, a fierce battle, serious injuries, and then... Lin Yu appeared.

It was he who saved himself.

Qin Xue looked at Lin Yu, her lips moving slightly: "Thank you."

"You're welcome, it's nothing."

Qin Xue pursed her lips, feeling a strange taste in her mouth, a faint fishy smell, yet also a warm sensation, and a lukewarm feeling in her throat.

What exactly is that thing?

"Sister..." Qin Xue turned to Qin Shuang, "What did you give me to drink?"

Qin Shuang blinked: "Water, you kept saying you wanted to drink water, so I poured you some warm water."

"Warm water?"

Qin Xue wondered, would warm water taste like this?

But she didn't delve into it; her mind was still foggy.

"By the way, sis," Qin Shuang sat down beside her, her expression turning serious, "Detective Lin has something to tell you."

Qin Xue looked at Lin Yu.

Lin Yu cut straight to the point: "Last night I found signs of damage to the wall outside."

Hearing this, Qin Xue's eyes turned cold: "What do you want me to do?"

"Come with me to stake out outside the wall; the target is very likely to make another move tonight."

Qin Xue did not hesitate:

"it is good."

With her parents' deaths and the need to secure the wall, she had no reason to refuse.
