"Master Jiang. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info" Lord Zhixian hurriedly stood up and saluted.

"Lord Yao is polite, the old man has resigned for many years, and now he is just a bad old man who teaches." Jiang Lao stopped and smiled unconcernedly.

"It turns out that the dean of our academy is a university scholar."

"Most of the books in the library were donated by Dean Jiang."

The students outside were all talking, but no one expected that this low-key old gentleman turned out to be a university scholar.

"Little girl, tell me how you got in without a key?" Jiang Lao was also really curious.

"Say yes, you can say, just!" Cheng Yao glanced at the people inside and outside the house.

"You all go back to class, write an essay on integrity, and turn it in in an hour." Jiang Lao commanded everyone to retreat.

"Yes, Dean!" All the students quit.

"Can you say it now?" Jiang Lao looked at Cheng Yao with a smile.

"Yes, old man!" Cheng Yao suddenly had a good impression of this transparent old man: "Actually, there are too many ways to enter this room without a key." Today I will tell you about the methods used by thieves. Instructor Wu, what is this room used for on weekdays? ”

"On weekdays, when I don't have classes, I often read books here and correct students' essays. It's close to the students' classrooms, and if they don't understand anything after school, they can come and ask me. ”

"Have you ever been locked on weekdays?"

"There are no valuables in the room, and it is rarely locked on weekdays. However, this is the teacher's room, and the students do not dare to enter it at will except for cleaning. ”

"Except today, when was the last time you were locked?"

"When I took the exam in the first half of the year, the gentlemen were here to mark the exam papers. Dropped the lock that night. ”

"How many days is this place cleaned?"

"Once every three days, that's when the students know to be grateful, and it's hard for me to refuse." Instructor Wu looked at everyone's expressions, and saw that everyone didn't think that he was instructing students to do things at will, so he breathed a sigh of relief, but he was still not angry in the face of Cheng Yao.

"When was the last time you cleaned up? Who cleaned it? After cleaning, did anyone else come in but the instructors? ”

"What's the use of asking this?" Instructor Wu frowned.

"To catch the real thief!" Cheng Yao looked righteous.

"Shaoting, whatever she asks, you will answer!" Jiang Lao spoke.

"Yes, Dean. The last time I cleaned was the day before yesterday, and the student who was supposed to clean was sick, and I cleaned it myself. On weekdays, the room is not locked, and I am not sure if anyone else came in before the lock. ”

"Okay, thank you, Instructor Wu. I'm going to show you how the thief got in! Cheng Yao took the lock and walked outside the door and locked everyone in the room.

"What is she doing?" The crowd whispered and discussed.

"Hey, I'm here!" Cheng Yao opened the window and greeted the people inside.

"How did you do that? After discovering that the silver had been stolen, I immediately checked the doors and windows, and it was clear that the bolts were in good condition. Instructor Wu was taken aback.

Cheng Yao smiled and didn't answer, just closed the window. Under the eyes of everyone, the wooden bolt of the window slowly fell again.

"What's going on? Don't sell it. Yao Zhixian urged.

"The design of this window is actually extremely unreasonable. With just one line, you can open the window at will outside. ”

The plug of the window is an LL-shaped when viewed from the front, and an L-and-an inverted L when viewed from the side. When the bolt is dropped, it becomes a horizontal fold (7) and appears at a right angle.

"This window bolt is so tight that it is impossible to open it with a rope." Instructor Wu questioned and stepped forward to check, and with a slight lift, the plug slipped out: "This is oil!" ”

"Yes, it's oil, lubricated with oil, and only a thin line can do it."

"That means you can pry it open with a knife?" Zhao Qi asked.

"The gap between the windows is so small that a knife will leave a mark. The thief is a very careful person, he does not make such mistakes. ”

"Then you have to touch the oil on the bolt in advance and release the line. If Instructor Wu went to open the window, wouldn't he find out? Yao Zhixian also raised questions.

"Then I have to ask Instructor Wu, why don't you like to open this window so much?"

"How do you know that I don't like to come to that window?" Instructor Wu asked rhetorically.

"The vase in front of the window is placed right in the place where the bolt of the window is dropped. If you have to open the window often, it's not very inconvenient! Just now I moved it a little bit away to make it easier for everyone to see my demo. There are also marks of dust on the table, which can prove what I said. Cheng Yao pointed to the table.

Yang Li stepped forward to check and nodded to everyone.

"Yes, I don't like to open that window, my nose is sensitive to pollen, and I sneeze when I smell pollen. And the window on that side faces the garden. Instructor Wu answered his doubts.

"That is, if you know Instructor Wu, the person who is used to it is a thief!" Yang Yang was delighted.

"Everyone in the academy knows about it!" Instructor Wu touched his nose in embarrassment, and as soon as spring came, he kept sneezing, which was really insulting. In front of the students, he also lost the appearance of a teacher.

"But when I came today, it happened suddenly. How could the thief know in advance and make such a layout. Qian Juren raised another question.

"Perhaps, he didn't mean to steal the silver in the first place." It's a question of nature, to say or not to say? The ancients paid more attention to people's conduct. Stealing money, maybe being squinted by money on a whim, or trying to save in an emergency. There are extenuating circumstances. If it is deliberately long-term, it will be determined that it is difficult to change its nature. Cheng Yao was really embarrassed, it was just a teenager, if he had such a brand, his whole life would be ruined.

"If you don't steal money, what are you going to do?" Yang Li was dizzy when he heard it.

"Master Yao, the old man has a reluctant request!" Jiang Lao got up and saluted Yao Zhixian.

"The lower officials should not be like this, and ask the boss to show it." Yao Zhixian dared to accept it, and hurriedly got up and returned the salute.

"The old man will make up for all the lost money this time. It's because the old man didn't have a good education, and I hope this matter can be solved by the county school itself. I also hope that Lord Yao and you will agree. ”

Naturally, the crowd agreed.

"The old gentleman thinks about the students everywhere and is an example for all teachers!" Cheng Bai understands Jiang Lao's behavior very well.

"Today, Brother Cheng has been stigmatized, it's all the old man's fault, please forgive me!" Jiang Lao solemnly apologized to Cheng Bai.

"Don't dare, don't dare! As long as I can look at it at will in the future, I will forgive everything in the collection of books in this county school. Cheng Bai took the opportunity to ask.

"That's nature, the books in the library pavilion, the old man donated them, the original intention is to let more people read them. Brother Cheng is studious, how can the old man not allow it! Jiang Lao was stunned at first, and then said happily.

"Then thank you, old man!" Cheng Bai was overjoyed.

"Brother Zhao, what's going on? The thief is not caught? Yang Li still didn't understand.

"Anyway, you don't understand." Zhao Qi didn't have the idea of solving the doubts of his pig-like teammates at all.

"What about the money?" As soon as Yang Li finished asking, he saw that the father and son of the Zhao family, the father and daughter of the Cheng family, were all staring at him. While everyone else looked at Cheng Yao.
