"What do you know?" Xu Changkun asked with a smile as he held Xu Jingjing's hand, and then gestured to Lin Feng, "Xiao Lin, please sit as well! I hope you don't mind me calling you that?"
"Hehe, not at all," Lin Feng thought to himself that this old man was truly no ordinary person, as he had seen through his cultivation level at a glance. However, Lin Feng's cultivation level was different from that of ordinary martial artists. His physical strength had reached the Late Earth Level, but he appeared to be at the Early Earth Level to outsiders.
"Doctor Lin, please have a seat. Let me introduce you, this is my grandfather, and this is my father," Xu Jingjing introduced them to Lin Feng one by one.
Lin Feng also quickly greeted the two, saying, "Mr. Xu, sir, good day to you!"
"Haha! Xiao Lin, your way of addressing us is too cumbersome! Mr. Xu, sir, I think you might as well call me Grandpa along with Jingjing and call him Uncle," Xu Changkun said with a laugh.
