"Doctor Nan?"
Cheng Yanzhao looked surprised at Nan Yan. "Are you Grandpa An's granddaughter?"
Nan Yan nodded slightly, then glanced at the elderly Cheng sitting on the sofa. "So, the old friend Grandpa mentioned was Mr. Cheng."
"Oh, you know each other?" Grandpa An was a bit puzzled.
He didn't expect that his granddaughter would also know Mr. Cheng.
Cheng Jingchuan's eyes sparkled with excitement. "Elder An, it was your granddaughter who saved my life. If it weren't for her, I probably wouldn't have survived this ordeal. I might have died..."
Grandpa An and Mr. Cheng were classmates at the same university when they were young, and they even shared the same dormitory. Their friendship had continued from their college days.
But in recent years, both of them had deteriorating health, constantly teetering on the brink of life and death. Even though they lived not far from each other, they hadn't met in over a decade.
