Old Yu, don't be fooled! You might end up losing your life!

"Old Qin, if you don't understand, shut up! You just can't stand me!" Old Yu glared at Old Qin, then quickly apologized to Lin Jin. Lin Jin waved his hand, indicating it was alright.

The next day, Lin Jin arrived at Old Man Yu's house according to the address. A middle-aged man opened the door. After learning Lin Jin's purpose, he looked suspicious but still invited her inside. Old Man Yu was overjoyed to see Lin Jin. Lin Jin began to treat Old Man Yu. Her technique was skillful, and she explained the precautions while administering acupuncture.

Just then, Old Yu's daughter-in-law returned. Hearing that a young girl was treating her father-in-law, she looked on with disdain! She crossed her arms and said sarcastically, "Oh, where did this little brat come from, daring to treat my father-in-law? Even the specialists at the big hospitals can't do anything. What skills does she have? Maybe she's just trying to scam money." Upon hearing this, Old Yu flew into a rage: "What do you know? This Miss Lin saved my life in the park yesterday. Her medical skills are superb!"

"Yu Xuemin, keep your wife quiet. This is my guest." The middle-aged man stood silently to the side, but from the look in Lin Jin's eyes, he knew he thought the same thing! Hearing his father say this, Yu Xuemin could only tug at his wife's sleeve, signaling her to stop talking. Lin Jin ignored the questioning gazes and continued to focus on treating Old Man Yu. She carefully adjusted the angle and depth of the silver needles, each movement precise and confident. As time passed, Old Man Yu's originally pale face gradually regained color. "Miss Lin, your acupuncture technique is amazing! I feel much better." Seeing this, her daughter-in-law's face turned very pale, but she still stubbornly said, "Maybe it's just temporary. How can it work so quickly?" Lin Jin smiled and said, "Auntie, treatment takes time. I will do my best to help Grandpa recover as soon as possible." Just then, Old Man Yu suddenly remembered something and said, "Miss Lin, I have a comrade-in-arms who is also seriously ill. Could you also take a look at him?"

When Old Man Yu's daughter-in-law heard that he wanted to introduce Lin Jin to Chief Li for treatment, she immediately objected, saying, "Father, Chief Li isn't someone anyone can treat. Besides, we can't bear the responsibility if he makes a mistake!" Before Lin Jin could answer, Old Man Yu became anxious, "I believe in Miss Lin's medical skills. She saved me, so she can definitely save Old Li." Yu Xuemin also advised, "Dad, why don't we ask Chief Li's opinion first?" Old Man Yu slapped his thigh, "Yes, I'll call and ask right now." He then went to get the phone.

A short while later, Old Man Yu returned with a beaming smile: "Old Li said he could come over to help him take a look sometime, he trusts this young girl!" Old Man Yu's daughter-in-law was even more displeased upon hearing this, muttering: "You trust someone you've never even met, you're all too easily fooled!"

Young girls these days really dare to say and do anything!

Upon hearing this, Lin Jin immediately became angry and said, "Excuse me, ma'am, I was trying to help your father-in-law with my best intentions. What did I do to offend you? Grandpa Yu, since you don't trust me, I'll be leaving now. Just pretend I was never here. Goodbye!"

After saying this, Lin Jin stood up to leave, but Old Man Yu quickly said, "Young lady, don't go! She's just being stubborn, don't take it to heart. Old Li's illness can't be delayed, please do me a favor and go see him." Old Man Yu anxiously grabbed Lin Jin. Yu Xuemin also hurriedly apologized, "Young lady, my wife is ignorant, please be magnanimous and don't hold it against her. Commander Li is really seriously ill, and we're counting on your help."

Seeing this, Old Man Yu's daughter-in-law dared not utter another word, but her face was still full of resentment. Lin Jin hesitated for a moment, then, considering Old Man Yu's trust and Chief Li's illness, nodded: "Alright, for Grandpa Yu's sake, I'll give it a try. It's a bit late today, let's go tomorrow."

Old Man Yu's face instantly lit up with a smile. He said with great joy, "That's wonderful, wonderful! You're truly a living Bodhisattva descended to earth!" Yu Xuemin, who was standing next to him, also hurriedly thanked him, his gratitude overflowing.

Immediately afterward, Old Man Yu suddenly turned to Yu Xuemin and said sternly, "You'd better keep a close eye on your own wife. From now on, you two shouldn't come here unless it's absolutely necessary!"

Lin Jin patiently explained some important points to Yu Xuemin. She also wrote a prescription, detailing the dosage and usage of each herb, and handed it to Yu Xuemin.

Yu Xuemin took the prescription and carefully put it away. At the same time, he took out ten ten-yuan bills from his pocket, intending to give them to Lin Jin as payment for the consultation. However, Lin Jin only took out five bills and said with a smile, "Fifty yuan is enough. You can get these medicines yourself at the pharmacy."

Yu Xuemin was somewhat surprised, but still nodded quickly to express his gratitude. Seeing this, Lin Jin turned to leave.

Old Man Yu watched Lin Jin's departing figure, hummed twice in dissatisfaction, then turned around and ignored Yu Xuemin and his wife.
