What the stationmaster said was, "I'm afraid." The meaning is obvious: Li Ya, although your story is reasonable, it is a lie after all. You doubt the story yourself. How can you fool Yu Zecheng? Moreover, the stationmaster specifically mentioned "1937 entered the system" and "students from Yu Lexing" 1937 entered the system for the first time, indicating that Yu Zecheng has entered the system for a long time and is very clear about its handling methods. Secondly, the stationmaster and Yu Lexing are classmates, and Yu Zecheng is a teacher. He is well aware of Yu Lexing's thoughts and teaching methods, and he knows how careful Yu Zecheng is. Your story can't fool him (the internal monitoring is normal, but the scope of your monitoring is a bit beyond your authority); Moreover, when the stationmaster heard about it, he didn't ask much. Li Ya said, "We are going to watch the Dragon Gang." As soon as the stationmaster heard it was false, he told Li Ya that it was not the words, but the tone and eyes (referring to the attitude when talking). Li Ya was worried that it was a lie, so when he said it, he subconsciously avoided looking at Yu Zecheng, so Yu Zecheng found the problem.
