Lu Zhi was talking about military formations, and Gongsun Zan called my name in front of everyone: Liu Zian was the only one in the class who could play with clouds. I lay on the table and just wanted to sleep, but the teacher said: There will be an assessment tomorrow, and whoever loses the formation will invite the whole class to drink. Gongsun Zan looked at me with raised eyebrows, his eyes full of provocation. I slowly straightened up: Teacher, are you sure you want me to be serious? I'm afraid he'll lose half a year's salary in one drink.
