661 The Temptation of Mysterious Paper!

What made Lin Feng both cry and laugh was the sight of Old Liu, such a highly esteemed scholar of the medical community, a senior figure, actually wearing a vest and shorts, standing at the elevator door, greeting Lin Feng!

If Old Liu's students saw this scene, who knows what they would think of this highly respected senior figure?!

"Old Liu, what's with this?" Lin Feng asked knowingly about Old Liu's attire, barely holding back a laugh.

"You rascal, quit playing dumb! Hurry up and come in! We old folks have all been waiting for you!" Old Liu didn't mind at all; he was always one to not sweat the small stuff, and he spoke directly to Lin Feng without any reservations.

Lin Feng uttered an "Oh" with laughter in his eyes, thinking that this old man was actually quite adorable!

Following Old Liu into room 602, Lin Feng saw four elders seated inside, all looking at him intently.
