So, Chen Yuan tapped Zhou Fu's arm with his pen.
Hmm?
Zhou Fu was puzzled and looked over, only to see Chen Yuan writing on his book:
A lost white ant met a black ant,
And the white ant asked the black ant, "How do you make it back to the anthill?"
What's that?
Zhou Fu was a bit bewildered, so she frowned and kept staring at him.
Then the black ant replied, "Do you return with a smile or in total silence?"
Huh?
After thinking for a moment, Zhou Fu suddenly got the joke and burst out giggling.
Chen Yuan also covered his mouth, trying to hold back his laughter.
"What are you two laughing at?"
At that moment, the biology teacher turned around and looked at Chen Yuan and Zhou Fu.
We're doomed!
Zhou Fu, realizing they had been caught by the teacher, quickly wiped the smile off her face.
Chen Yuan also quickly flipped the page over and lowered his head in silence.
That kid thinks he can slack off just because he aced the biology test?
