After returning downstairs, Bai yanzhenyu found the Mumu police department and asked the police to cooperate with him in an activity to find the real murderer.

Mu Mu police department still trusts Bai Yan Zhenyu. Under Bai Yan Zhenyu's guarantee, he agrees to his request, and according to Bai Yan Zhenyu's plan, announces to the new monks that today's investigation is temporarily over and leads the team to leave the new monk.

After Mumu police department and others evacuated according to the plan, Bai yanzhenyu went into the yard and got caught in the rain for a while, then nodded to Conan and signaled him to act according to the plan.

Then, Bai yanzhenyu took Conan back to the dining room where Maori xiaowulang and others were. He asked Mrs. Yangzi, "Mrs. Yangzi, I was wet by the rain outside just now. Can I borrow the bathroom here?"

"Well, yes." Mrs. Yoko agreed to Bai Yan Zhenyu's little request although she was a little confused.

"Thank you very much. You can actually test the new doctor's electric shock with an electric razor in the bathtub." Bai yanzhenyu thanked and turned to the bathroom.

After Bai yanzhenyu left for some time, Conan suddenly looked left and right and asked curiously, "ah? Where are those police uncles?"

Maori Kouro looked at Conan and said listlessly, "the Mumu Police Department said that when the investigation came here today, he left first. Really, it's not too late."

"Gone..." Conan shook his head and said regretfully, "that's a pity."

Xiao Lan, who was sitting on his side, asked, "what a pity, Conan?"

Conan blinked, pretending to be naive and replied, "because brother Zhenyu said that after he took a bath, he would gather everyone and reason about the truth of the case."

"Well?"

When they heard the speech, they were all stunned and looked at Conan in surprise. Xinchu Zhiming asked, "does Mr. Baiyan really say that?"

"Yes," Conan nodded and confirmed, "brother Zhenyu told me before that he already knows who the prisoner is."

"What murderer?" Mrs. Yoko tightened her heart, flashed a touch of panic at the bottom of her eyes, subconsciously got up and said, "is my husband's accident?"

Conan shrugged and replied, "well, I don't know very well. Brother Zhenyu said he would take a bath and sort things out at the same time, so he asked us to wait for him a little."

After listening to Conan, Maoli xiaowulang and others stayed in the dining room waiting for Bai yanzhenyu. Then after a long time, Bai yanzhenyu still didn't return from the bathroom.

Xinchuzhiming looked at his watch, frowned slightly and said, "twenty minutes have passed. It's been a long time for him to take a bath."

The wife smelled and complained impatiently, "it's too much. Who does he think he is? Let's wait so long."

Mrs. Yoko, who had just called again, opened the door and walked into the dining room. She smiled and comforted: "well, mother-in-law, brother Baiyan, I think it's almost ready."

Just then, there was another "click" in the dining room, and the whole house fell into darkness again as before.

"Eh? Power failure again?"

Although they were surprised, they only encountered such a situation once after all, and they all seemed calm.

Mrs. Yangzi went to the cupboard, found a flashlight from inside, opened it, handed it to breakeven light, and said, "Xiaoguang, please go to the switch and have a look."

"OK." the break even light answered and immediately ran to the switch with a flashlight.

Xinchu Zhiming frowned and said suspiciously, "didn't you just fix it? Why is there a power failure again?"

The old woman looked at the direction of the bathroom, raised her eyebrows and reminded, "I remember that child said he would do an experiment in the bathroom..."

After listening to the old woman's words, Maori xiaowulang and Xiaolan changed their faces and said in a panic, "wait, really feather him..."

However, before this sentence was finished, the light in the room was restored again, and the breakeven light at the switch was found. Officer Takagi, who had left, stood at the switch with dignified front color.

……

At the same time, Mrs. Yoko stood stiff in the bathroom with an electric razor in her hand, because Bai Yan Zhenyu, who should have bathed in the bathtub, leaned neatly against the wall facing the door and stared at her coldly.

Looking at Mrs. Yangzi's flickering eyes, Bai Yan Zhenyu shook his head and sighed slightly: "Mrs. Yangzi, the murderer is really you."

"You say I'm the murderer? Stop talking nonsense, will you?"

Mrs. Yoko put down the electric razor and sophisticated, "I'll come here, just because you said you wanted to use the electric razor in the bathroom for experiments. I'm really worried. I'll come and have a look."

"Ha ha," Bai Yan Zhenyu snorted and bluntly revealed, "in fact, you came here to kill people after Conan said I knew the identity of the real murderer, and then you will be the first discoverer."

Mrs. Yoko's face changed and explained, "you can't talk nonsense about things without evidence. I've been calling before the power outage."

"The reason why there was a power failure before was that you installed a timer somewhere, resulting in a short circuit. Later, in the dark, you came to the bathroom by lighting the pen lamp on your hand. When your husband took a bath, you put the extension cable into the bathtub. When the switch was pulled up again, he would automatically get an electric shock and die."

With Bai yanzhenyu's reasoning, Mrs. Yangzi's face became more and more ugly. After Bai yanzhenyu finished, she reluctantly made a helpless expression and retorted: "I've said that I've been talking on the phone with my friends since the power failure. How can I have time to do this?"

"It's impossible," Bai Yan Zhenyu explained with a cool smile. "It's much easier as long as you hold your home telephone and mobile phone in your arms in advance."

After listening to Bai yanzhenyu's words, Mrs. Yangzi looked flustered. Bai yanzhenyu took the opportunity to continue: "when you saw Miss breakeven leaving the dining room, the host changed the sub machine, took the sub machine to the bathroom, made a phone call to her home with her mobile phone, pretended to have a plug-in call, and temporarily interrupted the call."

"At this time, you walk into the bathroom, grab the socket of the plug * * extension cable, and secretly put the extension cable into the hot water. It is estimated that you said something to warn your husband, let him grasp the iron handrail next to you, and then return to the dining room while talking, change back to the receiver of the host, and wait for power on."
