But Sheng Di hasn't seen his sponsor yet. Now, Sheng Di lives in a shabby old apartment and leads a hungry and fulfilling life. This old apartment is the most chaotic place in the whole block, full of parolees and hooligans.
However, Sheng Di was not influenced by these people. He still studied profound mathematical principles behind closed doors every day and was indifferent to things outside. Mrs Millie, the apartment manager, is Sheng Di's only friend and often helps him when he is hungry.
On this day, Mrs. Millie remembered that she hadn't seen the flute for many days, so she went to his room 3 10. Knocked on the door for a long time, but there was no response. Suddenly, she found a pool of blood at the bottom of Sheng Di's door! Blood oozing from the door has solidified into a deep red. Mrs. Millie couldn't help screaming and ran downstairs to call the police.
The police broke into the house and found that Sheng Di had been stabbed six times and died a few days ago. He was lying on the ground with a twisted wire in his hand.
The murderer is obviously a professional criminal. He skillfully removed his fingerprints and footprints, took the murder weapon and left no clues at the scene. According to Mrs. Millie's recollection, she seemed to hear a fierce quarrel at Sheng Di's house a few days ago.
"Can you provide clues about the suspect?" The policeman asked Mrs. Millie, "Who do you think would do such a cruel thing?"
"Everyone in this building." Mrs Millie said, "They are all professional criminals. If it weren't for the low rent, Sheng Di wouldn't live here. What a nice man he is. He has always dreamed of becoming a mathematician ... "Mrs Millie couldn't help crying here.
"Wait a minute," a policeman said suddenly. "You said he dreamed of becoming a mathematician?"
"yes." Mrs. Millie choked up and replied, "He studies mathematics so hard all day, and he will certainly succeed!" " "
"Mathematicians ... wires ... circles ..." The policeman muttered, as if remembering something. A few minutes later, he looked up and said, "I already know who the murderer is." Let's arrest him! Sheng Di is really a smart man, what a pity! "
Clever reader, can you read the hints left by mathematicians and successfully find the murderer?
Result of solving a case
Before he died, Sheng Di grabbed a wire and made it into a circle, which showed that the police had something to do with this circle when they killed him. As we all know, pi is about 3. 14, so he means that the murderer lives in room 3 14. This is a mathematician's unique way of thinking. The clever policeman cracked his "password" after thinking and successfully solved the case.
