Just as xinchuzhiming and others were about to leave, officer Takagi returned from the outside and reported: "Mumu police department, I have confirmed with Mrs. Changjiang, who spoke to Mrs. Yoko during the power failure."

Mumu police department turned to officer Takagi and hurriedly asked, "Oh? What's the result?"

"The other party said that she was listening to Mrs. Yoko say that there was about a minute between the power failure and recovery."

Officer Takagi looked at Mrs. xiangyangzi and asked, "now, I want to compare the content of the conversation with you, OK?"

"Well," Mrs. Yoko nodded, and then said to the Mu police department in some embarrassment, "yes, yes, but can you wait until I help my mother-in-law deal with the wound?"

After hearing Mrs. Yangzi's words, Xiao Lan introduced herself and said, "well, if you don't mind, I'm willing to help Mr. Zhiming. To be honest, I'm quite skilled in this area."

"In that case, please."

Mrs. Yoko didn't refuse Xiaolan's kindness. After Xiaolan left, she began to compare the contents of the telephone conversation with officer Takagi.

After the comparison between Mrs. Yoko and officer Takagi, the Mumu police department nodded and said, "the content of the conversation is basically the same. In the middle, the telephone was interrupted for about six or seven seconds. So Mrs. Yoko really kept calling when there was a power failure."

After thinking silently for a while, Bai yanzhenyu asked, "Mrs. Yangzi, do you have a plan of the house? Can you show it to me?"

"Of course not."

Mrs. Yoko was very cooperative. She quickly took the architectural drawing of the house and spread it on the table for everyone to watch.

The new monk's house is a common Harmony House with neon. Its structure is very simple and clear.

"The bathroom where the new doctor died of electric shock is here..."

The Mumu police department first reached out and pointed to a position on the building plan, then moved to another position and continued: "the dining room where we are now should be here. Then, where is the position of the switch?"

"Here it is." Mrs. Yoko pointed to a position on the drawing and explained, "come out of the kitchen, go to the left, turn left, and then turn right when you get here. It's the end."

Baiyan Zhenyu carefully observed the structure of the house for a while. His eyes showed a look of thinking. He asked, "Mrs. Yoko, I remember when Miss breakeven left the dining room to turn on the switch, it was just when you told your friend that there was a power failure here, right?"

Mrs. Yangzi looked at Bai Yan Zhenyu, nodded and replied, "yes."

"In that case, it's too strange..."

Bai Yan Zhenyu blinked puzzled and doubted: "according to the distance marked on this drawing, it normally takes only 30 seconds from the dining room to the switch, but why did it take Miss breakeven a minute to restart the power supply?"

After hearing Bai Yan Zhenyu's words, Mrs. Yangzi quickly explained for the breakeven: "that's because Xiao Guang has just come here and is not familiar with the layout of our home."

Conan, who was lying beside Bai Yan Zhenyu to check the drawings, suddenly interrupted: "but when Mr. Zhiming saw the burn of the breakeven sister just now, he said that she liked to hide the wound from the past. Did they know each other before?"

"Yes," Mrs. Yoko explained with a smile, "when Zhiming used to study at Dongdu Medical University, the patient she met when she was an intern was Xiaoguang. She only knew how to bear when she was ill, and almost broke her cecum."

"Well..." they suddenly realized that Maori xiaowulang asked curiously, "is that why Miss breakeven came here to help?"

"Yes, my mother-in-law is also old. She wants me to take care of such a big home alone. She really can't take care of it, so she asks someone to help."

Speaking of this, Mrs. Yangzi was in a low mood and sighed, "it's really a little ashamed. Qianjing did all these before."

"Qianjing?... Oh, it's Mr. Zhiming's late biological mother." Mumu police department recalled in his mind, and then remembered who Qianjing was in Mrs. Yoko's mouth.

According to the situation of Ke Xue's world, the characters or events that have occurred many times may be the key clues to solve the case. Therefore, Bai Yan Zhenyu didn't avoid it. He directly asked, "you said she died in a car accident. Can you tell us in detail?"

After Mrs. Yangzi recalled it, she replied in a deep voice, "I heard it's drunk driving. She doesn't drink very much. So I can't believe this fact until now."

After hearing this, Bai yanzhenyu had some ideas in his mind, but he didn't have the evidence, so he didn't tell others.

At this time, officer Takagi suddenly asked, "well, where is the old woman's room?"

"It's on the second floor," Mrs. Yoko explained, pointing to the location of the second floor of the construction plan. "Turn right from the kitchen and go up the stairs. This big room is it."

"An old man sleeps on the second floor?" the police department frowned and looked at Mrs. Yoko puzzled. After all, in most families, those old people with inconvenient legs and feet live in rooms on the first floor.

Mrs. Yoko also saw the meaning of Mumu police department and helplessly explained: "because my mother-in-law likes this room very much and says that you can see the courtyard below from there, so I will arrange Xiaoguang's room next to her, so that even if there is any accident, Xiaoguang can find it in time."

Mumu police department realized that he had misunderstood Mrs. Yoko. He coughed awkwardly and stopped talking about this topic.

Maori xiaowulang, who had been thinking for a long time, suddenly brightened his eyes, came to the ear of Mumu police department and whispered, "Mumu police department, the murderer must have used the plug-in phone to distract Mrs. Yoko because of the phone, then slipped through the corridor in front of the dining room into the bathroom, and then put the extension line into the hot water."

After thinking about it, the Mumu police department felt that Maori Kogoro's reasoning was not very reliable, and asked, "according to what you said, didn't he be found when he returned?"

"Er... That's right." after Mumu police department made such a suggestion, Maori xiaowulang reacted and smiled back to his original position.

Seeing that the case was about to reach an impasse, Bai yanzhenyu had a flash of inspiration and proposed: "in that case, let's demonstrate what they did when the power was cut off, and maybe we will find new clues."
