Winters in Beijing are still quite cold. Although it's not as cold as Heilongjiang Province, it's not warm either. School starts a long way off, so it's impossible to just sit here and play every day. Soon the country will have new policies, and Lin Jin wants to seize this opportunity.

Meanwhile, in a military compound not far from Lin Jin, an elderly general was suffering terribly from an illness. He was afflicted with an extremely rare disease, and the local doctors were at a loss. The old general's family was frantic, searching everywhere for someone who could cure the disease.

Today is a big day! It's the old commander's birthday! All the younger members of the family have come to celebrate with him. The whole courtyard is bustling with activity and filled with laughter.

Li Yanjun arrived early in the morning with her two beloved sons to help prepare for the birthday banquet. Li Yanjun is the youngest daughter of the late Chief Li, and she places great importance on her father's birthday.

Don't let his stern demeanor fool you; Commander Li truly adores his children! Though he isn't good at expressing himself, his fatherly love is genuine. Therefore, Li Yanjun and her siblings deeply respect and love their father.

Their mother died early, and their father raised them all. Seeing their father suffering from illness day and night, they felt terrible!

After having dinner early, Li Yanjun took the children home. The children all had their own things to do, and she was very busy. Although Li Yanjun was very busy, she was always concerned about her father's illness. Whenever she heard of a skilled doctor, she would go to see him in person.

Meanwhile, Lin Jin was watching a group of old men play chess in a park! The old men were quite amusing; they even started arguing while playing!

Lin Jin had originally intended to watch the commotion, but suddenly one of the old men clutched his chest, coughed violently a few times, and fainted! "Old Yu, what's wrong with you... Oh dear... Old Yu..." This terrified the other old men, who paced anxiously in circles. One of the younger ones quickly ran to call for help!

Lin Jin quickly went over to check on the old man, taking his pulse and examining his eyelids. He discovered the old man suffered from asthma and had likely fainted from the sudden excitement. Lin Jin first laid the old man flat, then used silver needles to insert needles into the old man's Tanzhong and Feishu acupoints. Several other old men nearby stared at Lin Jin in astonishment, unable to believe that such a young man could use silver needles, and so decisively at that! The old man woke up shortly after. Lin Jin helped him up, and just then, the old man who had gone to fetch help returned with several others. Seeing the old man sitting on the ground, though his complexion was poor, they all breathed a sigh of relief.

Old Yu looked at Lin Jin and quickly said, "Young lady, thank you so much today. If it weren't for your help, I would be in grave danger." Lin Jin smiled and waved her hand, "You're too kind, it's what I should do. You must be careful in the future, don't get too emotional. You already have asthma, and your blood pressure is a bit high! If you faint again, it will be troublesome. You should go to the hospital for a check-up now!" Several other old men nearby chimed in, "Old Yu, you should go see a doctor!"

As soon as Lin Jin finished speaking, she turned to leave. However, just as she took a step, Old Man Yu suddenly reached out and grabbed her sleeve.

"Young lady, wait a minute!" Old Man Yu called out hurriedly, "You saved my life today, but I still don't know your name! Where do you live? I must thank you properly!"

Lin Jin stopped and replied with a smile, "Grandpa, my name is Lin Jin. You don't need to be so polite. Studying medicine is all about saving lives!"

Old Man Yu didn't seem to give up because of Lin Jin's words. He continued, "Miss Lin, since you were able to accurately diagnose that I have asthma and high blood pressure, do you have any way to cure these ailments?"

Lin Jin thought for a moment, then said, "Grandpa, high blood pressure can usually be well controlled by paying attention to your diet and doing some appropriate exercise. However, asthma treatment might be a little more complicated. It would take about twenty days to completely cure it."

Upon hearing this, Old Man Yu's eyes lit up, and he tightly grasped Lin Jin's hand, saying, "Miss Lin, I'm willing to pay any price to cure my asthma! You must help me with this." Looking at Old Man Yu's expectant eyes, Lin Jin felt a pang of reluctance to refuse, so she nodded and said, "Alright, Grandpa, I'll try. But I don't have my medicine with me right now. How about this, give me your address, and I'll come to your house to treat you tomorrow." Old Man Yu was overjoyed and quickly gave Lin Jin his address.

Some people nearby said with doubt: "Even the experts in big hospitals can't cure this disease, how can a little girl like her cure it?"
