The famous criminal in the world of Conan

"But Xinghe Tongwu is different. He followed Himimiya Nobuko upstairs from the beginning. After he killed the man, he could have observed our movements from upstairs based on the sounds."

"If we don't go upstairs, then he will wait until dinner time to drag other people upstairs, and then find the body to prove his alibi, just like the current situation."

"And if we go upstairs temporarily, he can also start the technique directly, or just improvise with us."

"Of course, I am more inclined to believe that Xinghe Tongwuta killed someone in the heat of the moment."

"Passion killing?"

Sato Miwako frowned slightly.

"You mean to say that Xinghe Tongwu's killing of Himimiya Nobuko was not a premeditated act, but an accident?"

"At present, this possibility seems very high,"

Bai Masong took two steps and came to the bottom of the curtain. He looked at the pole of the curtain and said lightly,

"Although his methods can fool people temporarily, generally speaking, they have many flaws."

"Especially in this case, normally, if Fan Tianli hadn't gone into his room to sleep and never come out, and if Tanaka Takahisa hadn't gone out because of a lack of seasoning, then Xinghe Dougo would have been the only one who went upstairs in the entire Zhengying family."

"A good magician, or a criminal who deliberately wants to commit murder, would not leave such an obvious mistake."

"Too,"

Sato Miwako nodded, her face full of approval.

"Although we have currently identified three suspects, in fact, if there were not so many special circumstances, only Xinghe Tongwu could have committed the murder."

"That's right,"

Bai Masong first confirmed Sato Miwako's statement.

Then, he took two steps into Master Zhengying's room and came to the table with a pile of books and photo albums. He quickly searched through them while continuing to analyze.

"And don't forget, the person who proposed this event at Zhengying's house was actually Fan Tianli. Xinghe Tongwu had no intention of coming here at the beginning, so it was naturally impossible for him to design a method of killing people here."

"Makes sense."

Miwako Sato nodded repeatedly.

Looking at it this way, the more I analyze it, the more I feel that Xinghe Tongwu has big problems and many flaws.

but......

Miwako Sato suddenly raised her head and looked at Baiba Song who was still searching for something.

"You just said that he designed a method of killing people here?"

"You mean, the way he moved Himimiya Nobuko's body can only be done in this place?"

"So, have you figured out his method?"

"Um,"

Bai Masong nodded slightly.

Then, the hand that was quickly flipping through books and photo albums stopped moving, and his hand stopped on a photo in one of the photo albums in front of him.

"found it."

Bai Masong murmured softly.

Seeing this, Sato Miwako curiously walked over to Bai Masong and leaned over to look at the photo album in front of him.

"What did you find?"

"This is...Master Zhengying?"

Miwako Sato was completely confused.

The photo album on the table in front of her and Bai Masong was open. The page she turned to depicted a kind, tall and thin old man in a robe. He had a smile on his face and was pointing his hand to the side. Where he was pointing, there was a Christmas tree full of gifts standing tall.

"What does this mean? Isn't this a photo recorded by Master Zhengying?"

Sato Miwako was puzzled.

A smile flashed across Bai Masong's lips.

“No, it’s not just a photo.”

"This is still the method used in this case."

"Eh?"

Miwako Sato exclaimed,

"Does this photo record the methods used in this case?"

"Um,"

Bai Masong hummed lightly, and then began to speak, not knowing whether to himself or to explain.

"Mrs. Zhengying and Fan Tianli listened to our description of the case and reacted quickly. They worked together to weave a lie, which shows that they already knew the murderer and his method."

"In other words, it was because we immediately thought of the method that we were able to identify the murderer in the first place."

"But why did they think of the technique immediately? There is only one possibility, that is, this technique has appeared in front of them more than once."

"Fan Tianli is a magician, and Mrs. Zhengying is the wife of Master Zhengying. The tricks that keep appearing in front of them are most likely magic tricks, and this trick is very likely to have been used for more than ten years."

"Combined with the fact that everyone knows this, a technique that Fan Tianli, Xinghe Douwu, and Masaaki Masako knew about more than a decade ago, but others, including Mr. Harui Fuden, who is also a magician, don't know, then the most likely possibility is-"

"This technique is the unique technique of Master Zhengying, and he has performed it many times in front of his disciples."

"Combined with the fact that Master Zhengying likes to leave records of his techniques and various photos, I think there is a high probability that there is a trace of this technique in the album here."

"I found it very quickly. If you think about it carefully, the position occupied by Master Zhengying is right here in this corridor. Is the Christmas tree behind him the position where Miss Himimiya Nobuko's body is?"

"He was showing everyone this Christmas tree with a smile on his face. Isn't the most likely possibility that he was showing everyone something that suddenly appeared or changed?"

"To put it together, the Christmas tree suddenly appears, and then the master Zhengying introduces his magic trick to the guests who are all incredulous. This is the content of this photo."

"Well, does it sound very similar to our case?"

After Bai Masong finished speaking, he left the table and walked to the door of Master Zhengying's room, looking at the door carefully.

After listening to Bai Masong's words, Sato Miwako thought for two or three seconds and suddenly realized.

"So that's how it is. Xinghe Tongwu killed someone in a rage, and then he found that everyone was sitting downstairs. If I just go downstairs like this, when the body is discovered, the murderer will be identified directly."

"So, in a desperate situation, he thought of his master, Master Zhengying's technique of restoring the disappearing Christmas tree. He then used this technique to perform a magic trick for everyone and disguised the surrounding environment in an attempt to create the illusion of a thief's invasion to mislead the police."
