"It's the medicine to treat Big Brother's illness!" Susu thought Lu Zhanyu knew about it.
Lu Zhanyu's expression tightened, then he looked towards the direction of the door.
Old Master Lu and Butler Zhang just happened to come in.
"Grandfather, do I need any other medicine for my recovery?" Lu Zhanyu asked urgently.
"Ah?" Old Master Lu's face changed dramatically, his gaze darting around, his expression panicked.
Although he knew that this matter couldn't be concealed forever, being suddenly questioned by his grandson still made Old Master Lu unavoidably panicked.
"Grandfather, just tell me straight," Lu Zhanyu said sternly.
"Zhanyu, don't be anxious, you have to trust Grandfather, I will definitely find the medicine for you," Old Master Lu hastily explained.
"So it means it's very hard to find," Lu Zhanyu understood the implied meaning in Old Master Lu's words immediately.
