Beisitian had heard of this elderly man before. When he came to get medicine last time, she had listened to his story, so he wasn't entirely unfamiliar to her.
The elderly man's condition was entirely due to his injuries, which everyone knew as the cause, but treating it properly was indeed very challenging.
Currently, there isn't any advanced medical technology available domestically to remove so many fragments from his body. Even if it were possible, due to the elderly man's age, a single anesthesia procedure might be too risky, and he might not wake up from it.
Moreover, the elderly man also suffers from myocardial infarction, making surgery even more difficult, so he can only rely on medication.
The elderly man initially took painkillers, but consuming such medication excessively is harmful to the body. Eventually, the effectiveness reduced significantly, and he had increased the dosage to five pills per meal!
