"I know the work and rest of this family and the exercise habits of the victim better than anyone. It's easier to arrange organs than anyone. Even those who enter the living room earlier than anyone after the crime... Only the husband of the victim, Zeng Wei Guizao!"

In the face of Bai Yan Zhenyu's identification, Zengwei's face suddenly lost its color and retorted, "you're nonsense. Why should I kill my wife?"

"Why?" Bai yanzhenyu raised his eyebrows, pointed to the album put aside by Zeng Weigui, and said with a smile: "I think the answer is hidden in that album“

Hearing Bai yanzhenyu say this, officer bainiao immediately took the album and opened it for everyone to see.

The album is full of photos of Zengwei's husband, wife and friends, but some people's heads are circled by Mrs. Zengwei.

"If I'm not mistaken, these people marked by Mrs. Zengwei are the bandits who robbed the bank not long ago, and Mr. Zengwei is likely to be the leader of the robbery."

Baiyan Zhenyu pointed to the characters in the photo and said to Zengwei Zao, "Mrs. Zengwei must want to take this photo album to the police station and tell officer Takagi the information of the robber, so you killed Mrs. Zengwei“

"Yes, you know very well that your wife will use the exercise bike at 2 p.m., so you can roughly estimate the time when the dagger stabbed her."

Officer Sato followed Bai Yan Zhenyu's hint and suddenly realized, "no wonder you have to call in the office. It was to let us do an alibi for you."

Officer Takagi also figured out all this and later realized, "I see. You restored the fallen bookshelf when we went to the second floor, didn't you?"

"This... Would you please stop joking?"

Zengwei Guizao raised his hand to wipe his sweat and retorted, "if there were many policemen coming here at that time, there would be one policeman who would enter the living room before me. Moreover, if I fixed the dagger on the bookshelf, I must still leave the dagger on the bookshelf now."

"No, the dagger doesn't need too much complex fixation."

Baiyan Zhenyu wants a piece of cardboard, folds it into the shape of a dagger, then piles the books at the lower layer of the bookshelf on the three empty layers above, and inserts the dagger into the gap between the books at the top layer and the top plate of the bookshelf.

"Like this, just fill the top layer with books, and then clip the knife in the seam of the book."

"In this way, you don't need adhesive tape to fix it. Moreover, due to the increase of the weight above, the bookshelf is easier to fall down. The blood at the top should be stained when you fall down."

"Yes," Bai Yan Zhenyu's reasoning was recognized by everyone, and officer Gaomu was surprised to agree: "in this case, after stabbing the victim, the dagger stayed in the victim's body, and the books naturally scattered out. As long as you pick up the bookshelf, put the books away and put them on the lower floors, it is not easy to arouse suspicion."

Zeng Wei Guizao smiled modestly and explained, "but if I put the dagger on the bookshelf, my wife should notice."

"It's very simple. As long as you put a few notebooks on the top of the bookshelf, you can hide the dagger that seems a little abrupt."

Baiyan Zhenyu took out several notepads and put them directly above the paper dagger. The originally conspicuous paper dagger was immediately covered by the shadow of the notebook.

Zeng Wei Guizao refused to plead guilty and continued to retort: "this... These are just your reasoning. What evidence is there to prove that I arranged the mechanism?"

"Evidence? Of course, that is, the components that make up this mechanism, that is, the transparent tape and pushpin that hang the thin line."

"There are neat blood stains on the top of the bookshelf, indicating that there was something stuck there;"

"Considering the problem of thin line, we can guess that he fixed the pushpin upside down on the top of the bookshelf. After the thin line pulled down the bookshelf, the thin line can be separated from the top and drawn into the central shaft of the toothed disc under the inertia of the fitness bike."

Baiyan Zhenyu looked at Zeng Wei Guizao confidently, reached out and pointed to each other's pockets, sneered: "Mr. Zeng Wei, can you take out the things in your pockets for us to see?"

"What?!"

Hearing Bai yanzhenyu's words, Zengwei Guizao's face became more ugly and subconsciously covered his pocket.

Seeing the reaction of Zeng Wei Guizao, people were more convinced of Bai Yan Zhenyu's speculation, and stared at Zeng Wei Guizao, who was trembling all over.

The white bird officer looked solemn and ordered in a deep voice, "Mr. Zengwei, please take out the things in your pocket."

"Alas, I didn't expect you to find out... Yes, I killed gadai."

After a few seconds of silence, Zengwei Guizao took out some blood stained transparent tape and pushpins from his pocket with a bitter smile and admitted the crime of killing his wife.

After Zeng Wei Guizao pleaded guilty, Bai yanzhenyu followed the police back to the police station and went to police officer Gaomu to record a confession with Bu Mei and others.

The arrested Zengwei Guizao also explained the information of his robber associates under the police's interrogation. Then the police quickly attacked and arrested all the other robbers, successfully solving the two related cases.

Soon after, Baiyan Zhenyu and others recorded the confession of the blue castle case, and then left the police hall together.

Seeing that it was getting late, Bai Yan Zhenyu invited everyone to have dinner in a nearby restaurant. After having enough wine and food, he sent the three people of Bu Mei home. Then he said goodbye to Dr. Ali and ash Hara, and took Conan back to Maori office.

……

Before going to bed, Bai yanzhenyu entered the system space again and began to draw rewards for this event.

Baiyan Zhenyu looked at the content on the turntable and found that the rewards were very hip pulling. They were fragments of intermediate skills and the lowest level attributes. There was nothing good to look forward to.

"System, draw."

Baiyan Zhenyu randomly extracts. After the turntable stops, he obtains [resilience fragment (0.1)] that can slightly improve his attributes.

After absorbing the system reward, Bai yanzhenyu enters the task interface and starts today's cooking [Master assessment].

After countless failures and summaries, Bai Yan Zhenyu had a deep understanding of magic Mapo Tofu. Through repeated attempts, he gradually found out the secret of cooking, and the score gradually increased to more than 90 points.

According to the previous high scores, Baiyan Zhenyu fine tuned the proportion of several spices to make today's cuisine, and then submitted it to the system for evaluation.
