On the second day of the Lunar New Year, the sun shone brightly, and the streets were bustling with activity, filled with people carrying various gifts to exchange New Year's greetings. However, in stark contrast to this joyous atmosphere, Lin Jin was alone, carrying her medicine kit, hurrying towards a secluded alley.

Although the alley was narrow, it was bustling with people. Lin Jin quickly weaved through the crowd and soon arrived at Liu Yilan's door. She stood before the door, about to raise her hand to knock, when suddenly a sharp voice came from behind her: "Who are you? What are you doing here?"

Lin Jin was startled by the sudden sound. She quickly turned around and saw a brightly dressed, fashionable middle-aged woman standing behind her, staring at her suspiciously. The middle-aged woman had a rather mean appearance, with wide, glaring eyes that sent a chill down one's spine.

Faced with the middle-aged woman's questioning, Lin Jin did not answer immediately. Instead, she glanced at her quietly and then continued to knock on the door. "Knock, knock, knock," the knocking sounded particularly loud in the quiet alley.

Seeing that Lin Jin ignored her, the middle-aged woman's anger flared up instantly. Her voice became increasingly shrill, as if it could pierce eardrums: "I'm talking to you! Why are you like a block of wood? Don't you know how to respond to others? How rude of you!"

Lin Jin frowned slightly, stopped knocking on the door, slowly turned his head, and looked at the middle-aged woman expressionlessly. His gaze was calm and indifferent, without the slightest ripple.

"Someone like you has the nerve to talk about manners?" Lin Jin's voice was as calm as still water in a deep pool, yet it contained an undeniable power. "Manners are always relative, aren't they?"

The middle-aged woman was clearly not expected Lin Jin to respond in this way. Her face turned even uglier, and she trembled with anger. She reached out to grab Lin Jin's collar, but the moment she met his gaze, she was so frightened by his icy eyes that she quickly withdrew her hand.

However, even though she had withdrawn her hand, the middle-aged woman continued to mutter, "Hmph!" Although the sound was not loud, her dissatisfaction and resentment were obvious.

At this moment, the door opened, and Liu Yilan came out. Seeing that it was Lin Jin, she happily led Lin Jin into the house. The middle-aged woman saw Liu Yilan but didn't even look at her. She just led the little girl inside, and the anger that had been pent up inside her suddenly burst out!

She shouted loudly, "You, Liu Yilan! My mother is gone, my brother is gone, and this is how you treat me! Do you even have the demeanor of a sister-in-law?!" Liu Yilan stopped and turned back to look at her coldly. "You still have the nerve to say that? Where were you when my mother was sick? Where were you when your brother had his accident? What kind of skill is this, throwing a tantrum like this?" The middle-aged woman's face flushed red. "You… don't think I don't know why you called this young girl here. You're definitely up to no good." Lin Jin stood behind Liu Yilan and calmly said, "I'm a doctor, here to treat Comrade Xiao. If you continue to be unreasonable, don't blame me for being impolite." The middle-aged woman felt a little intimidated by Lin Jin's cold gaze, but she still retorted, "You think you, a little girl, can treat patients? I think you're a fraud."
