Su Nanzhi couldn't laugh anymore.
When she couldn't laugh, her classmates laughed.
It was well-known that Su Nanzhi didn't participate in the military training, at least every classmate of hers knew.
The person on stage was the calculus teacher, who became more curious about this female student after seeing the reaction of the classmates.
Su Nanzhi stood up reluctantly, thought for a while, and simply empathized, "The sun is strong, standing at attention seems very tiring."
The calculus teacher responded with an "Oh," paying particular attention to the keyword: "Why 'seems'?"
Su Nanzhi then gave a nonchalant smile, "Because I didn't participate."
The teacher understood, the joys and sorrows of people are not interconnected, someone laughing is purely because she's just watching the show.
He nodded for Su Nanzhi to sit down, then called on a male classmate, "This male student also laughed particularly happily just now, you answer the previous question."
