In the kitchen of our library, Dr. a Li stares at the newly made cream cake and smashes it on his mouth. Seeing that no one enters the kitchen, he has a big appetite. He cuts a piece of cake with a knife and forks it into his mouth.

Not bad

"Doctor?" Gao Cheng and Xiaoqiao Xianjian follow the maid Miss Quan into the kitchen and are stunned to see Dr. Ali.

"I'll come and have a look..." Dr. Ali excitedly hid the knife and fork behind his back, and grinned with a guilty face.

"By the way, doctor," Gao Cheng looked at the cream cake strangely, "when we send Yuantai back, we'll also bring some snacks for Xiaoai."

"Good..."

"Miss Quan, do you have the biscuits of yesterday?" Gao Cheng turned to the maid and asked.

"I don't seem to have any, but I can make some more," the maid said after boiling water. "Mr. Chenghu, help me with the sugar. It's in the cupboard above."

"Sugar..."

Gao Cheng opens the cupboard door and finds the sugar. He suddenly notices that there are many switches on the wall.

"Miss Quan, is this the main switch of grape hall?"

"Well," the maid was stunned, "because I usually deal with everything here..."

"Does everyone else know?"

"Anyone who has been here knows?"

"So..."

Gao Cheng handed the sugar to the maid and frowned.

Yesterday, Jingze met Huo Si Xingzi who went out from the kitchen. It was just after 12 o'clock, that is, when the magic light in the single room went out. If the magic light went out at first, it just turned off the power switch between the ceremonies, the five minutes after Huo Si Xingzi left would be very suspicious.

The time for Huo Si Xingzi to return to the living room is 12:12, just after the magic lamp lights up again, which only Huo Si Xingzi can do in time.

Between the ceremony, Gao Cheng returns to the scene of the murder.

Huosi Xingyao's body has been taken away by the police, ready for autopsy to determine a more accurate time of death, but other aspects still try to keep the original appearance.

For Gao Cheng, when he encounters a crime with super high intelligence quotient, he must avoid taking it for granted reasoning. Otherwise, it is easy for him to get into the trap preset by the murderer. The best way to get rid of this is to return to the origin, deduce all the clues and details he has mastered, and explore the murderer's idea and purpose.

And this case, it seems, is also a crime of high intelligence quotient, and has the shadow of Gao yuanyao, the puppet master of hell.

First of all, we need to make clear the meaning of each layout of the murderer, which is either confusing or profound. The murderer deliberately let people see the curse doll first, and then let the corpse of the same death method appear in front of the public, so that everyone's attention turned to the curse doll, and some ignored the strange death method of the victim

Gao Cheng goes to the magic lamp again with both hands.

The question now is why the murderer set up the scene of the murder in the middle of the ceremony, and specially wrapped wires around huosi Xingyao's neck.

It is because of this clue that the police can judge the time period of travel by monitoring the magic lamp extinguishment

"Master!" Kentaro inouzawa and Kenzo Obuchi arrived at the ceremony together. They squinted and said with a smile, "I heard that you ran here suddenly. Did you find anything?"

Gao Cheng gathered up his thoughts and shook his head to them: "there's nothing to find, but..."

After a speech, Gao Cheng's eyes fell on the wall clock. The pendulum was swinging normally, but the time on the dial was a little slow. To be exact, it was about 11 minutes slow, which coincided with the time when the magic light went out last night.

"Is this wall clock... Not mechanical, but electronic?"

"Wall clock?"

Kenji obfuscated to look at the wall clock, Leng Leng, in front of a sudden bright, excited to embrace Gao Cheng.

"I see, Chenghu! The time is 11 minutes slow, which is the same as the time when the magic lamp is not on. If the wall clock is powered by power, that is to say, it was not the magic lamp plug that was pulled out last night, but the power was cut off during the whole ceremony! "

"Power off?" "What do you mean?" he said

"Don't you understand, yantaro," he said. "At the tea party yesterday, we really didn't have time to unplug the magic lamp. But if the lamp goes out and lights up again, it's not because the plug is unplugged, but because the power is cut off here? The switch is right there in the kitchen of our library. It won't take long if the power is cut off. Did you see Miss Xingzi come out of the kitchen yesterday? "

"Wait... Wait," Kentaro inazawa interrupted anxiously. "Xiaoqiao, are you doubting Miss Xingzi?"

"Don't you think she's hiding something from us?"

"The magic light went out at 12 o'clock yesterday, and miss Xingzi walked out of the kitchen just after that. Did you see that? Only she has time to turn on the switch... "

"But..." "it's not just that," Xiaoqiao said more and more definitely. "It was 12:11 when the magic light came on again. At that time, she was the only one who was not in the living room. She said that it was 12:7 when she went to make tea and 12:12 when she went back to the living room. During this period of time, she probably went to the place between the ceremonies to arrange the scene, Then go back to the kitchen and restore the switch... "Kentaro Inoue shook his head:" but it's only five minutes. It takes a lot of time to run back and forth. What's more, Xingzi really made vanilla tea and brought it back to the living room... "" what if Jiuyao was killed before that? " "Now the presumed time of death is 11:30 to 12:30, isn't it? According to the past experience, the specific time will be between 11:45 and 12:15. Before the tea party, you can kill Jiu Yao, hide the body between the ceremonies, and then go to the kitchen of our library... "Even if you really make vanilla tea, you may have prepared the tea bag in advance. It's too late to boil water temporarily..." "no way!" Yasutaro Inoue looks ugly. "Miss Xingzi can't be a prisoner!"“ Yantaro... "Xiaoqiao Xianjian chases yantaro inazawa, who has been hit. During the ceremony, Gao Cheng is left alone to find a police officer to check the wall clock. As expected, there is a power supply socket behind the wall clock, so there is no place for winding. As long as there is electricity, it can go on. Indeed, there is only one maid in such a large place as the grape house, and the mechanical wall clock will only increase the workload. But... Gao Cheng goes to the window and looks at our villa. Is the killer really Huo Si Xingzi? Both motive and action can be said, but doubts still exist, because as long as the police continue to investigate, sooner or later, they will think that Huo Si Xingzi did not leave a way for herself, leading to the end that only she did not have an alibi. Or is there any other basis for the fire worship of Xingzi?
