"After Miss breakeven opened the switch, the iron handrail held by your husband immediately generated electric leakage, which led to electric shock and death. That's why the leakage circuit breaker fell down immediately."

When Mrs. Yangzi saw that Bai Yan Zhenyu said her modus operandi, her heart sank. She calmed down and explained, "Mr. Bai Yan, although what you said is very possible, it doesn't mean that others can't sneak into the bathroom to commit a crime? Why do you only doubt me?"

"Yes, others are possible, but of all the people present, you are the most suspect."

Bai Yan Zhenyu agreed with Mrs. Yangzi's statement and explained with facts: "your plan is to use the telephone to make an alibi for yourself. It's also because you've been standing in the corridor outside the dining room. At the same time, you can also make an alibi for others. However, there's a lack."

"What are you talking about?" Mrs. Yangzi frowned and looked at Bai Yan Zhenyu puzzled. She didn't know where her plan was wrong.

Baiyan Zhenyu showed a confident smile and explained, "Miss breakeven took more than 30 seconds on the way to the switch. In this way, her alibi could not be established. Why did she take so long? Do you want to know?"

Mrs. Yangzi looked at Bai Yan Zhenyu in disbelief and wanted to know the answer to the question that puzzled her very much.

"It's a cup. When there was a power failure, Miss breakeven was cut by a broken cup in the dining room, so she put her under her arm. Before she went to turn on the switch, go back to the room on the second floor and see you hide it in the closet. This is because the new doctor warned her in the evening that if she made another mistake in the future, she should be asked to leave."

After hearing Bai Yan Zhenyu's explanation, xinchaoyang's face changed and suddenly realized: "so, did the scald on her arm leave at that time?"

"Yes, the burns on her arm and her mother-in-law's feet were all done at that time. It should be that the old woman walked out of the room in the dark and accidentally stepped on the debris that Miss breakeven fell on the corridor."

Bai yanzhenyu explained the reason for the two people's injury and continued: "if Miss breakeven wants to return to her room, it will indeed take more than 30 seconds. The old woman's injury can also prove that she did stay in the room on the second floor at that time, so both of them were excluded."

"As for Mr. Zhiming, although there was no light in the room at that time, I could hear that someone had left the dining room, so the only possible killer was you, Mrs. Yoko."

Bai Yan Zhenyu's reasoning made Mrs. Yangzi completely stunned. After a moment, she sighed: "Xiaoguang is too stupid. Even if you hide the cup, you will know immediately as long as the number is wrong. If Xiaoguang doesn't have this accident, I won't be suspected."

"No, even if it doesn't happen, we'll still doubt you."

After listening to Mrs. Yangzi's words, Bai yanzhenyu shook his head and explained, "before Miss breakeven left the dining room, you used to cover the receiver with your left hand. Later, after you called, you didn't know why you changed to your right hand, so you probably left the receiver with both hands during this period."

"In addition, the reason why you and miss breakeven went to the bathroom to check the situation of the new doctor is to avoid giving her an electric shock. Later, when Mr. Zhiming came, if I didn't prevent direct contact with the new doctor's body, you should also stop him."

"Worthy of being a detective's family, you are right in everything..."

Mrs. Yoko nodded calmly and admitted, "yes, because Qianjing asked me to take good care of Zhiming."

Seeing Mrs. Yangzi loosen her confession, Bai yanzhenyu immediately relaxed a lot and asked curiously, "Mrs. Yangzi, can you tell us why you killed the new doctor?"

"Four years ago, on the night of Qianjing's car accident, she called me and said, 'take good care of Zhiming and don't let that child become like my husband'."

Mrs. Yoko looked up slightly, with a trace of sadness in her eyes. She recalled: "at that time, I didn't know what she meant. I didn't understand what she meant until I found Qianjing's diary after I married him. It turned out that he was a scum man who liked to flirt. He was the culprit of Qianjing's addiction to alcohol, which led to her car accident."

After hearing the motive of Mrs. Yangzi's crime, Bai yanzhenyu was silent for a moment. Unexpectedly, there was such a secret in it.

After a moment of silence, Bai yanzhenyu looked solemn and suggested, "Mrs. Yangzi, if you can, I hope you can turn yourself in to the police."

"Oh?" Mrs. Yoko naturally knew that surrender could reduce the sentence, and said with a smile, "you are very kind."

Baiyan Zhenyu looked at Mrs. Yangzi and said seriously, "this is not only for you, but also for Miss breakeven to live at ease."

Mrs. Yangzi frowned and said, "what do you mean? Why do you mention Xiaoguang?"

Looking at Mrs. Yoko, who hasn't responded yet, Bai Yan Zhenyu smiled bitterly and explained, "Mrs. Yoko, don't you understand? Although you set the murder trap this time, it was Miss breakeven who turned on the switch. If she knew this, she would blame herself all her life."

"This..."

After Bai yanzhenyu mentioned this, Mrs. Yangzi remembered how serious the killing of others would have an impact on the introverted breakeven light.

"Mrs. Yoko, I have a suggestion. You can say that you are a drug addict. After the new doctor came out, you put him into the bathtub, set the extension line for installing the timer to electrocute him, and then take back the timer when the power is cut off, so as not to involve miss breakeven."

Mrs. Yoko is a kind-hearted person and likes the clumsy but diligent breakeven light. She nodded immediately and promised, "OK, I will turn myself in to the police according to this statement."

After Mrs. Yangzi promised to turn herself in, Bai yanzhenyu left the bathroom with her and said it was an evacuation. In fact, they squatted in the Mumu police department in the dark.

After the case came to light, Mu Mu's police department took Mrs. Yangzi back to the police station, and Bai Yan Zhenyu and others left here together.

Before going to bed at night, Bai yanzhenyu drew a lottery according to the usual practice. When his luck broke out, he drew a skill that was extremely useful to him.
