One-year solution 1W+. What strange cases did Di Renjie solve?

Di was the most famous expert in case-solving in the Song Dynasty. He enjoys the reputation of the Oriental Sherlock Holmes in history, and his fame has also caught up with the selfless Bao Qingtian. During his tenure in Chang 'an Dali Temple, he even set a world record for solving crimes, that is, all the accumulated17,800 cases in one year were decided, and almost no one objected to Di Renjie's judgment. It can be seen that he not only solved the case quickly and fairly, but also showed his superhuman wisdom and ability to solve the case. In history, he has also solved many strange cases, such as lacquer screen case, broken finger case, gold case, nail case, royal pearl case and so on.

During Di's tenure as the secretariat of Luozhou, he once went on a private visit with his entourage traveling incognito and found a monkey playing with a ring when he passed a hillside covered with pine trees. Because of his professional sensitivity in solving crimes for a long time, Di Renjie immediately realized that everything happened for a reason. After carefully examining the environment, he found that the body of a man was hidden in a secret cave, and his four fingers were cut off, leaving traces of wearing a ring on the broken fingers. Di Renjie concluded that the ring should come from the male victim.

Di Renjie continued with keen intuition. When he passed a roadside drugstore, he found that the knife cutting medicine in the store was so sharp that he could cut off several fingers at once. So his intuition was triggered again, and he went in and said he wanted to try the knife. But the shopkeeper Dong in the drugstore said not to touch it! Maybe your finger will be cut off! Di Renjie had something to say after judging the shopkeeper's words, so he ordered an investigation in this area when he returned.

Before long, the truth came out. It turns out that there is a beautiful street performer near here. Jia Sheng from Chang 'an likes her very much, but the entertainer asked Jia Sheng to cut off a little finger to show his sincerity. Soon, Dong Sheng, the son of drugstore owner Dong, passed by here. When he saw the beautiful entertainer, he came up to pester and flirt, but Jia Sheng beat him up. Dong Sheng was very angry. But Jia Sheng doesn't know Dong Sheng's true identity. A few days later, he went to the drugstore and asked the shopkeeper Dong to help him take a knife and break a finger. When the shopkeeper Dong started, Dong Sheng came back, picked up the pestle and hit Jia Sheng on the back of the head. As a result, Jia Sheng was killed on the spot with excessive force, and the shopkeeper Dong also cut off Jia Sheng's four fingers in a panic. At this point, there is no other way. Uncle Dong dumped Jia Sheng overnight, but it got worse every day.
