Leap.

Jane stood there like a statue of stone when she heard his words. The boy looked at her straight and then he started laughing with a hand on his mouth. Loud noise in the corridor can disturb the other students and Shi lang did not want to be scolded for this but the expression on Jane's face was like that. 

The girl had her eyes wide open and her mouth was big enough to fit an egg inside without breaking it. When she saw the boy laughing she pushed him away and said, "Bastard, trying to play me for a fool. See how I beat you to the pulp." 

Shi Lang chuckled lightly and said, "I surrender, almighty Jane. By the way, how is the physical growth of the class?"
