Li Fei looked at the Japanese beauty and laughed, "I'll help you go from 'o' to 'O'."
Then he turned around and left, leaving the Boduo College beauty with a bewildered look on her face.
(Ps: It's really a classic joke! Someone as pure as me doesn't quite understand it, so if you get it, go stand in the corner…)
Li Fei returned to the classroom, where a bunch of boisterous youths crowded around him; their excitement clearly hadn't cooled down yet!
"Brother Fei, keep teaching!" Their enthusiasm was unprecedented.
"To be continued, don't go away, the ads will be over soon!" Li Fei said as he walked to his seat; he just wanted to lie down and get some good sleep.
After all, the exertion of performing the Invisibility Technique had already drained a lot of his energy, not to mention the humming and hawing in the car just now had left him feeling quite tired.
