"There are still five minutes until school ends at noon," the class teacher looked at his watch, "then let's talk about physics questions." He turned around and started writing on the blackboard.
After 5 minutes, the head teacher finished drawing the force analysis diagram.
Jin Tongchen felt that no one but her heard the school bell.
Jin Tongchen was sitting on pins and needles, ready to move. There is a ramen shop outside the school that is so delicious that you have to fight to get a seat. She had been looking forward to the delicious food all summer long, and it was not worth it to be delayed by a physics question that she would never be able to solve in her life.
Jiang Yi had already solved the problem in 5 minutes. He noticed that his female deskmate was fidgeting and asked in a low voice, "Do you want to go to the toilet? This problem will probably take another 20 minutes. How about you take advantage of him when he's not paying attention?"
Jin Tongchen imitated the young man in red and patted him on the shoulder with loyalty: "Okay, comrade, I will withdraw first. If you are lucky, I will bring you some stinky tofu." While the class teacher was busy moving books, he quietly slipped out of the back door.
Stinky... Stinky tofu... Toilet... Jiang Yi's spinning pen fell off with a "clack".
