Li Yundong said with a smile, ”you've seen too many advertisements!”

Li Yundong nodded: ”yes, do you know what blood depends on to drive walking?”

Feng Na didn't know. She shook her head and said, ”I don't know.”

Li Yundong said: ”it's Qi! The so-called Qi and blood, Qi is the commander of blood! Without the command of Qi, blood can't go anywhere!

Feng Na suddenly said, ”Oh, so it is, but does this have anything to do with chewing and swallowing?”

Li Yundong smiled and asked, ”can you breathe in indefinitely?”
