"How can I open this mouth?"

Thinking of this, she felt depressed, and said with a strong mouth: "Thank you, young master, for your kindness. I can handle it myself, but I can't make an appointment for your dinner. I'm really sorry..."

Ye Chen casually said: "It doesn't matter what the dinner is, you should take care of your family affairs first, and we will make an appointment for another dinner some other day."

Wang Dongxue said gratefully, "That's really thankful, young master!"

Ye Chen smiled lightly: "It's okay, you don't have to be so polite with me."

Speaking of this, Ye Chen wanted her to be busy first, so that he would not delay her busying with family affairs, but at this moment, he heard a man's voice on the other end of Wang Dongxue's phone: "Ms. Wang, we have found the source of your father's poison!"

At this time, Wang Dongxue was still holding the mobile phone, but when she heard this, she completely forgot that she was still talking with Ye Chen, and she blurted out nervously and asked: "Captain Sun, where is the source of the poisoning you mentioned?" ?!"

Sun Wenbin was holding a heavy book in his hands wearing latex gloves, and said, "Our criminal investigators found that every sheet of this book contains mercury dichloride!"

"Also, we found that there are many traces of flipping this book. It is estimated that your father has read this book more frequently recently."

"When he usually reads this book, his hands will be continuously contaminated with mercury dichloride smeared on it, a small part of which will be directly absorbed through the skin, and part of it may be taken by him when he takes food. We ate it together with the food into our stomachs."

"Also, when the previous generation read books, they often had a bad habit of licking their fingers with their tongues when turning pages. I don't know if your father has such a habit?"

Wang Dongxue nodded lightly, and said: "My father does have this habit of reading... I told him before that flipping through books like that is unhygienic, but their generation has long been used to it, so this The problem has never been corrected..."

Sun Wenbin nodded and said, "That's right, I think the excess mercury dichloride in your father's body came from this book!"

As if struck by lightning, Wang Dongxue blurted out, "Captain Sun, did someone intentionally poison my dad?!"

Sun Wenbin nodded, and said: "From the smearing process in the book, mercury dichloride is in the form of a very fine powder, which is completely spread on the paper. In this way, it is almost colorless and odorless. , it is also difficult to identify, so it can be inferred that this is definitely man-made, and the other party is very cautious and has a strong sense of anti-reconnaissance!"

Wang Dongxue said angrily: "My father has taught and educated people all his life, and has never offended anyone. Who on earth would do this to him!"

Sun Wenbin hurriedly asked her: "Do you know how this book came about?"

Wang Dongxue nodded hastily, and said, "This book was sent by a courier my father received before the Chinese New Year."

Sun Wenbin was overjoyed, and asked: "Then who is the sender?!"

Wang Dongxue shook his head, and said: "At that time, the courier did not fill in the sender's information, but just brought a note inside. The person who wrote the note claimed to be a student my dad had taught before. He said I found this book by accident when I was abroad, and I knew my dad would like it, so I bought it and gave it to him.�

Sun Wenbin frowned and asked, "Without the sender's information, didn't you suspect it at the time?"

Wang Dongxue sighed, and said with great self-reproach: "My father has been teaching and educating people for half his life, and he has taught countless students. Many students often send him some books by mail, including books published by themselves, or they are in foreign countries. Some of the lonely copies I found, my father often mailed some books he had read to his students..."

"You also know that the most common gift that academics give each other is books, so we really didn't take it too seriously..."

Sun Wenbin frowned, and asked, "Is the express package still there?"

Wang Dongxue shook his head: "My mother cleans those things every day."

Sun Wenbin asked again: "What kind of express company was it at that time, do you remember?"

Wang Dongxue thought for a while and said, "It seems to be an international courier from the Postal Service, sent from Greece."

Upon hearing this, Sun Wenbin sighed, and said, "It seems that there are no clues to be found..."

Wang Dongxue hastily asked: "Why?"

Sun Wenbin explained: "If it is really sent from Greece, it will be detected by the customs when it enters the customs. The inspection methods of the customs are much stricter than ours. Many clever people who want to cross-border drug trafficking through similar methods will It was detected by the customs, so it is impossible for this kind of book smeared with poison to be delivered to your home..."
