Xu Sheng had a jolt in his mind, suddenly remembering that he had deliberately asked Tang San to wake him up yesterday. He felt a little embarrassed and scratched his somewhat messy hair, hehe smiled and said, "Xiao San, I'm sorry!",Just as he was lost in thought, a series of rapid knocks sounded from outside. "Thump thump thump...",Xu Sheng came back to his senses and looked towards the door, his tone a little puzzled as he said, "Come in!"。
