Tokyo, city household coffee shop, Gao Cheng has nothing to drink afternoon tea, Conan found to come over.

Just came back from Osaka, the impact of the flying boat incident is not over. Conan also has a lot of feelings about this incident. Different from Gao Cheng's systematic withdrawal of cards, this guy is purely enjoying this exciting experience.

The more capable people are, the more they pursue challenges. Whether it's Conan or the black charcoal face of the service department, he seems to be old-fashioned by contrast.

There is no interest in pursuing challenges. In addition to not wanting to bury the truth in solving difficult cases, it is mainly because the card can be drawn, and the more special the case is, the greater the harvest will be.

Speaking of it, he has robbed many special cases from Conan all the time. No wonder Conan always thinks that he has no passion in handling cases and wastes those wonderful cases in vain.

In fact, it's already very good. If he still remembers the case, it will be even more boring. At least there are challenges now. He never feels that he is invincible in the detective industry.

Arrogance is enough to defeat a famous detective. He still remembers the evil result of wrong reasoning, far from the trouble caused by wrong reasoning before, only sometimes the tragedy caused by jinrunya.

In this world, detectives who have a lot of say have to be responsible for their own reasoning. Every homicide is no small matter

"Oh, UFO, and such things?" Hearing Conan tell the story that Xiaolan mistakenly took a flying boat as a UFO when he was a child, Gao Cheng looks up at Conan.

Bad, because of the flying ship, I completely forgot what I promised to investigate UFO with Tian yangnai.

"It was the first time I saw a flying boat at that time, like a big balloon," Conan said with emotion. "I've heard Xiao AI say that anyway, thanks to Chenghu, you can make everyone's first flying boat trip without regret."

"Another day."

Gao Cheng doesn't care to chat with Conan. He listens to this guy talking about what happened with Xiaolan. After drinking his coffee, he leaves the office and goes to Beihu park to investigate.

Not far away, he didn't even ride a motorcycle and went straight to the park.

He still remembers the location mentioned by Hetian yangnai. When he went up the middle stairs, UFO flew between the two trees. When Hetian yangnai, who was running just below, caught up with him, he disappeared.

Gao Cheng looked around casually.

Before the summer vacation, the teacher of Beihu primary school was attacked and pushed down the stairs here. He had heard about this. At that time, few people came to Beihu Park, so that they had to install monitoring in the park to improve.

However, this also led to the fact that only Hetian yangnai witnessed any UFO.

Gao Cheng compared the map of Beihu in his memory, looked at the direction of Beihu high school, and then calculated the UFO flight route.

He Tian Yang Nai said suddenly disappeared, probably

"Why?"

Gao Cheng stops by a big tree and looks at the black plastic bags looming between the branches and leaves. He is very surprised.

It's October now. It's several months since Hetian yangnai witnessed the UFO. Are things still in this place?

The black plastic bag is very big. Although it can't be seen from the tree, it seems to match what Tian yangnai said.

Gao Cheng didn't move the black plastic bag. He just took a picture and turned to Beihu high school.

Now it's almost certain that what Hetian yangnai saw was not a UFO, but because of the detective's professionalism, he still wanted to investigate the origin of the black plastic bag.

Ordinary black plastic bags can't become long tubes and fly in the air.

Kuihu high school, although Xiaolan has always won the championship in the Kanto karate competition, Hotan yangnai, who is the leader of Kuihu high school, has not won once, but the karate department here is actually quite powerful, because jingjizhen was originally a student of Kuihu high school.

Conan rikyo is really the strongest high school student. He passed through Japan at a young age, and he has not lost a single game abroad. Because he has no influence from the garden, he has kept a winning streak and is even more famous than in the original book.

Affected by this, the karate atmosphere of Beihu high school is stronger than that of Didan high school.

Gao Cheng touched his chin.

It seems that every time she competes with Hetian yangnai, Xiaolan is very angry because of Kudo. In this way, the girl is not weak

"Oh! Senior

Outside the wall of the school building at the side of Beihu high school is full of students. Hetian yangnai, who is wearing blue sportswear, stands on the side of the wall. When he sees Gao Cheng, he is so excited that he waves.

"Senior, this way, this way!"

Gao Cheng immediately noticed several police cars parked at the gate of Beihu high school and looked at the side door surrounded by students: "what's the matter?"

"We are still decorating the school building. Someone died in the construction site," Hotan Yang Nai looked at the school building, showing a trace of fear on his tender face. "It seems to be a homicide. The police are investigating inside."

Even a karate master, Hetian yangnai hasn't experienced a homicide. She is still a high school girl and is quite uncomfortable with the death on campus.

Gao Cheng looks inside the school through the iron fence of the side door. Behind the school building not far from the side door, there is a piece of concrete land. This meeting has been surrounded. There are police investigating on the side, and there are also many students watching and talking from afar.

According to these students, it seems that the deceased is not a student of our school. The lock of the side door is broken. The deceased entered through here and finally died in the cement field that has not yet solidified. Gao Cheng vaguely saw two human shaped depressions in the enclosed concrete field, and some footprints“ Don't crowd here Chiba came to the iron fence to disperse the students and said, "go back to the classroom quickly!"“ Chiba Gao Cheng appears in front of Chiba after the students leave“ So it is, "Gao Cheng and Chiba stood outside the cement field." this morning, when the construction workers came back to check the setting condition of the cement, they found that someone fell in the cement... "" the one who was killed was Gongwu nakazu, 42, editor of UFO magazine, "Chiba explained." when they found him lying on the ground, his face was embedded in the cement, and the cause of death was suffocation, However, the autopsy found that no cement was inhaled. It should have been poured on the cement after being killed... "Next to Mr. nakadzu, the unemployed Mr. nakadzu, 38, often sends photos to Mr. nakadzu for contribution."“ Is the rotten wood alive? " Gao Cheng took the scene photos to check“ Yes, half a year ago, someone saw that they had a big fight in the editorial department, so we think Kuki has a very strong motive for committing the crime. " Chiba replied. In the scene photos, Hideki did lie on his back next to the victim, wearing a hooded coat and a hat. It looked like he was lying on purpose in the cement field“ Mr. nakadzu was strangled by a bag on his head, but no similar weapon was found at the scene. I was investigating around just now. There was no strong wind yesterday and today. It's impossible to be blown away by the wind. It won't be too far to throw away stones... "Chiba said“ Rotten wood said that people were not killed by him. He said that he fainted after seeing a strong light. But it's really strange. Yesterday was the time when the ceremony was held in kitako town. It was very hot. However, the guy not only wore a coat, but also a hat before fainting. He almost knew that he would fall in the concrete field. " Gao Cheng looked at the scene photos for a while. After returning them to Chiba, he squatted down and pressed his fingers on the solidified concrete floor. Like an electric shock, a picture flashed through my mind. When he saw the scene, he knew that deadwood Xiongfu was a criminal. Although deadwood's body fell in the cement and covered many footprints, he was able to restore part of the scene. This man followed Zhongjin's editor and walked into the cement floor, then covered Zhongjin from behind. After Zhongjin's body fell down, he put on his hat and fell in the cement, Remove suspicious traces while pretending to be unconscious“ When the construction workers found the rotten wood, "Chiba continued," he and Mr. nakadzu had been firmly fixed in the cement. It took a lot of effort to get them out. If the rotten wood didn't wear a hat, his hair would be stuck in the cement. It would be more difficult to save it. How do you think this guy is a criminal, But... "Gao Cheng got up and said," I just saw a monitor installed on the street light outside the side door. Did you get any pictures? " Chiba Leng, when did you notice the monitoring“ Yes, there's surveillance. I've confirmed the video, but, "Chiba said." surveillance only caught them walking into the school from the side door. Because of the angle, they didn't get to the side of the concrete ground. "“ Just the two of them? "“ Yes, at first we thought about the possibility of accomplice, but no matter it was the side door or the front and rear doors of the school, we didn't see other suspicious people coming in and out. By the way, they did get a strange thing soon after they went in... "Chiba explained to Gao Cheng with a terrible face“ From top to bottom, the huge, slender and creepy shadow running through the whole picture goes to the direction of Beihu park opposite the fence... "Gao Cheng looks back, a little boring. Across the road is Beihu Park, which should be the source of UFO. It's just a big black plastic bag with a long tube shape... It's just that Hetian yangnai witnessed it in the summer vacation, but the homicide happened yesterday evening, with several months between them.
