Professor Yao did not walk into the classroom alone.
Behind him was a young female janitor in a grey robe, sporting a ponytail and a stern face.
As always, the professor strode onto the podium, slammed his lecture notes onto the podium desk, and then habitually dusted off his sleeves.
Meanwhile, the two janitors stood silently at the classroom door, not uttering a word, as if they were statues.
The students' curious eyes wandered between the professor and the janitors, and many couldn't sit still, whispering to each other. The atmosphere in the classroom became a bit eerie.
"No need to get nervous, no need to get nervous," The professor caressed his shiny bald head, suddenly grinned, revealing his yellowish teeth, "Remember, before the end of the last class, I mentioned we would discuss your understanding of 'Guardian of the Original Morning' at the beginning of this class."
The classroom immediately turned into a field of mourning.
