章 687: Chapter 687: Hidden Disease

Seeing Grandpa's appearance, Li Zifeng was greatly surprised.

Grandpa had never lost his composure like this before.

Who exactly was that person?

Why had Grandpa become so excited after reading the letter from that man?

He was just about to invite that person in, following Grandpa's instructions.

But at this moment, Li Qingcang said, "Forget it, I'll go with you to invite him in!"

"What?" Li Zifeng was even more shocked, "Grandpa, who exactly is that person, that you would personally go to invite him?"

Li Qingcang said solemnly, "Don't ask too many questions. All you need to know is that you should respect him just as much as you respect Grandpa... no, even more than you respect Grandpa!"

Having said that, he didn't wait for his grandson Li Zifeng's shock to settle before heading toward the door.

Li Zifeng was stunned for a long time before muttering, "Who exactly is that young man?"

...

Lin Dong had been waiting at the door for about five minutes.
