Lu Changyu bowed with his fists clasped, "Greetings, young master."
Lou Ze was sizing up the decent-looking man in front of him, a puzzled look in his eyes, "We do not know each other, so what brings you here seeking help from me?"
Lu Changyu earnestly said, "A few days ago, my family's servant went out to buy vegetables and saw the young master use a pill to save someone addicted to 'divine ointments.' Your medical skills are extraordinary, so I wanted to invite you to come and check on my father's illness."
Lou Ze asked, "What's wrong with your father?"
Lu Changyu, feeling desperate, said, "He's addicted to divine ointments too, and he can't quit it no matter what. He's almost at his end."
Lou Ze was puzzled, "Isn't your family secluded? How did he even get addicted to that stuff?"
Lu Changyu's voice was indignant, "Someone deliberately harmed him; it wasn't my father's doing. He detests divine ointments and would never touch it on his own."
