Sunday, January 23rd, night, Miyamoto house.

When Yamazaki and Midaiko arrived home, they were just in time for Meidai's restaurant to close, just in time to help.

The family had a late-night supper, cleaned up the Mai Dai restaurant, and returned to the house upstairs, where Miyako Miyamoto contacted Belinda via satellite video.

After greeting each other, Belinda asked funny, "Mei Daizi, how was it, did you have a good time on this train trip?"

Mei Daiko complained, "It's not good, it's too time-consuming on the road." ”

Belinda said with a smile: "That's why there is a faster means of transportation like an airplane, although the supersonic passenger plane is noisy, you need to pay more take-off and landing fees in terms of noise, but even if the airline is not used as a flight, it will be used as a charter flight, the reason is that the speed is fast, speed is time, and money is used to buy time, and it is worth it." ”

"Alright, when is it time to become a salesman?" said Miyamoto, "Come, tell me about the experiment of the Athena launch vehicle." ”

"Today's launch mission is normal, and you have passed the exam. Belinda said, "Using my standards, the unified production of things, perfect compatibility, perfect fit, there will be no problem." ”

"The advantage of production line production is that if something has a problem, there is a problem with the whole batch, and it will not be a single one. ”

"Although the assembly is manual, the standard is unified, and the size and internal structure of the final product should be exactly the same. ”

"After comparing the computer self-test program with the radiographic scan, the problem can be found at once. ”

"For you now, it is not necessary to improve the Athena launch vehicle, the carrying capacity of fifteen tons in low orbit is enough, just use this template, batch by batch. ”

"When the production line is idle, some production lines that produce launch vehicle-related components can produce other things, which saves some costs in disguise. ”

"If you want to use a more advanced and lower-cost commercial launch vehicle, start another project, and slowly study it, it is a time-consuming and laborious thing. ”

"The improvement of the launch vehicle is best in the experiment, and it is best to use the template type in practice, because every time the improved launch vehicle is used, it is the first time and cannot be fully controlled, and the template launch vehicle has had successful experience before, as long as it is repeated and done, it can be said that it can be controlled. ”

Miyamoto Miko said: "What you say makes sense, but I have a question, what do I want so many launch vehicles for." ”

"My chip level has entered 50 nanometers, I decided not to wait, next I will upgrade the deep space communication satellite system, satellite network system, I have also applied for the space dock, planetary mining two business projects. "There are dozens of satellites in the satellite network system, and you can share some of them when the time comes." ”

"In such a hurry?" Miyakoto asked, "And it's all your own money, isn't it?"

"In a few years, there will be an asteroid worth trillions of dollars that will pass by the Earth, and the distance will only be more than 30,000 kilometers," Belinda said. ”

Mei Daizi smiled: "Planet Mining, this is interesting. ”

"I'm sure you have what it takes to capture this asteroid, but how do you want to bring the minerals back to Earth?" Miyamoto asked, "Not to mention the transportation costs, what about invasive species?"

"Invasive alien species invade the earth?" said Mei Daiko with a smile, "This is a fun, realistic version of a sci-fi blockbuster." ”

Belinda said: "Don't worry, although I haven't figured out how to bring the minerals back to Earth, there is no such thing as species invasion, and the detection of life is still very simple, it takes some time each time." ”

"I haven't figured out how to bring the minerals back to Earth," Miyamoto Miko asked angrily, "So what is your income?"

"Ah, you're stupid this time, Miko, aren't you?" Belinda said with a smile, "How to bring minerals back to the earth, it depends on the price of minerals in a few years, first of all, the return capsule is carrying, five tons of empty cabin up, it is not a problem to bring dozens of tons of minerals down, minerals are a solid dead thing." ”

Mimiko Miyamoto asked angrily, "Oh, then what's next?"

"Secondly," Belinda scratched her face and said with a dry smile, "The second is space smelting minerals and supporting space colonization." ”

Mimiko Miyamoto said with a smile: "This pit, you are digging bigger and bigger." ”

"Judging from the operation of the space hotel, space colonization can already be experimented, that is, the technology of space smelting needs to be tested slowly, but in theory, smelting in a microgravity environment is much simpler than on Earth. Belinda said, "Anyway, get the asteroid first, and the valuable minerals on it are the foundation." ”

"Well, that makes sense. Miyamoto said, "Okay, nothing else, that's it." ”

"I have a question. Midaiko asked, "How do you build a spaceship in a spacedock?"

"With the current technology, it is impossible to build a spaceship in space, it is just assembled, and various parts are sent from the earth into space, and then assembled. "The spaceyard is a relay station. ”

"Then the spaceship is like a space station?" asked Midako, "just more propulsion?"

"At present, it is almost the same, because our current human beings cannot live in a microgravity environment for a long time, so the manned equipment in space for a long time has to artificially create gravity, and it is a mature technology to create gravity by centrifugal force through rotation," Belinda said, "so my spacecraft is also in the shape of a section, only the landing module is a spacecraft." ”

Midaiko asked, "The landing module landed on a planet?"

"Of course," Belinda said, "the fact that the earth cannot be lifted directly does not mean that it cannot be lifted directly on other planets, and in the case of the moon landing, the reason why only three people can go up is that the launch vehicle can only send such a heavy thing to the moon at a time, and if there is a place to stop and replenish on the way, or even have accompanying supplies, more people can enter and exit." ”

"Oh, I see. "Spaceships are supply stations. ”

"Yes at the moment, and it won't change for quite some time. Belinda said, "In science fiction movies, spaceships that fly directly from the earth to the moon may appear in 100 years, but due to fuel constraints, they can't bring a few people on board." ”

"Got it. Mei Daiko said.

"Okay, it's late on my side, so let's stop here. Miyamoto said.

"Bye-bye. Belinda cut off contact. ……

The next day, Monday, January 24, Metropolitan Police Department.

In the morning, Officer Yumi hurried through a search class, thinking about the news he had overheard near the vending machine last night.

According to reliable sources, the headquarters of a theft gang that has been committed all over the country are located in Tottori Prefecture, and the Tottori Prefectural Police have offered to cooperate in the case, and the Metropolitan Police Department also needs to be dispatched.

And because, this theft gang has injured people in Tokyo, and the incident at that time was to search for the hands of a class, and now a person will be sent over.

Celibate, capable, and physically able to withstand difficult tasks in other counties, familiar with local conditions.

Officer Matsumoto consulted with the Twilight Police Department to let Officer Takagi pass, and this is three years, three years......

"Late, late. ”

Officer Takagi hurried to the office, and last night because of Officer Sato's change of attitude, he was too excited and fell asleep very late, but he got up late in the morning and was still woken up by the phone.

"Ah, I'm sorry, I'm late ......"

When he opened the door, Officer Takagi didn't finish his words, and found that the colleagues in the whole office were not ridiculing themselves, but looking at him with a strange gaze, and they could see that they were hairy, what was going on?

"Takagi. Officer Yumi looked at Officer Takagi.

"Ah, Officer Yumi, you're here too. Officer Takagi laughed.

Officer Yumi's tears came out, "Goodbye, goodbye, Takagi." Tears ran away as he spoke.

"This, this ......" Officer Takagi was completely stunned,

"Ah, Takagi, I have good news for you. The colleagues laughed gloatingly, and talked about Officer Takagi's transfer to the outside world.

"Huh, expatriate?" Officer Takagi thought that the call that woke him up in the morning was indeed from the Twilight Police Department, but he was in a daze at the time, and he didn't hear what was said clearly, and it turned out that he was sent to Tottori Prefecture.

Officer Takagi smiled, "It's okay, I'll definitely solve the case as soon as possible, and then I'll be able to come back." ”

"As soon as possible?"

"Don't you know?"

"The location of the incident of that theft syndicate involved multiple parts of the country. ”

"It takes a lot of time to investigate and collect evidence. ”

"If there are too many prisoners, it will take even more time. ”

"It's set for three years. ”

Listening to his colleague's words, Officer Takagi was stunned, "What? three years!"

Seeing Officer Takagi's shocked appearance, the Shiratori Police Department was overjoyed, three years, 1,095 days, 26,280 hours, and God really did not abandon me.

"Isn't that great?"

"Tottori Prefecture is a great place. ”

"Pine leaf crabs are cheap there and can eat a lot. ”

"You can also ride a camel on the Tottori sand dunes. ”

Officer Takagi recovered and exclaimed angrily, "I'm not going to ride a camel." ”

"Takagi. Officer Sato stepped forward, and the office fell silent.

"Twentieth Century Pears," Officer Sato smirked, "that's my favorite." ”

"Huh?"

Officer Takagi, who was nervous about what Officer Sato would say, was discouraged, and the office burst into laughter.

At this time, Matsumoto came in with a black face, "What are you doing here!"

The office suddenly fell silent, and everyone awkwardly returned to their respective positions. ……

In the afternoon, after receiving a report that there was a homicide, the Twilight Police Department asked Officer Nagasuke to take Officer Sato and Officer Takagi to dispatch.

Before leaving, he told Officer Takagi, "Officer Chosuke is my senior, so I should listen to him and learn more." ”

"Yes, police department. Officer Takagi replied, and then hesitated to ask the Twilight Police Department about the assignment again, and fight for it? No, that's not good, right?

"Also, this may be the last time you will work together, cherish it. The Dusk Police Department said.

"Huh?" Officer Takagi's morale was greatly reduced, so there was no need to ask any more questions. ……

The location of the incident was the 32nd floor of a high-rise apartment in Rice Flower 4-chome, and it was found that the person was a woman in her thirties, crying so much that there was no way to investigate.

The deceased, a man of about 30 years old, died at the entrance of the room, and the murder weapon was a kitchen knife, which was inserted into the deceased's chest.

It appears that the killer stabbed the deceased in the chest when he answered the door.

There have been no similar cases recently, that is, it is not an indiscriminate killing, the prisoner did not happen by chance, but knew the deceased, it was a targeted killing, and the prisoner was a person known to the deceased.

After listening to Officer Takagi's analysis, Officer Nagasuke praised, "That's a good point, so where to start?"

"First of all, the caretaker in the lobby downstairs," Officer Takagi said, "the prisoner must have met with the caretaker when he came into this apartment." ”

"And so. Officer Chosuke asked.

"The second is to investigate the deceased's recent contacts with the deceased's acquaintances. "Finally, an investigation was conducted around the building to see if anyone had seen any suspicious people." ”

"Okay, then let's start the investigation in the three directions you said. Officer Chosuke said, "Officer Sato, you go down to the administrator first." ”

"Yes, Senpai. Officer Sato replied. ……

Soon after, Officers Sato and Takagi returned and reported to Officer Nagasuke.

Officer Takagi said, "Senpai, Mr. Administrator, around 6:45 in the morning, saw a man wearing a full-length raincoat come in. ”

Officer Sato said, "The reason why I think he is suspicious is because he didn't take off his raincoat when he came in, and he came down the safety stairs later." ”

Officer Takagi said: "But it was raining today, and Mr. Administrator thought he was a resident who was running in the morning, or a guest who forgot something and came back to pick up something, and he was in a hurry, so he didn't pay much attention, and it was not clear whether it was a man or a woman." ”

Officer Sato said, "Also, this person is one hundred and seventy-five centimeters tall when he is wearing a full-body raincoat, and his body is not bloated, and he is not fat. ”

Officer Takagi said: "This person was wearing a gray-black full-body raincoat, and no one went upstairs at that time, and this person went upstairs on the second elevator alone, and I have asked someone to block it and wait for investigation." ”

Officer Sato said, "Mr. Administrator said, and then I saw a person wearing the same gray-black full-body raincoat as this person, walking down the safety stairs. Then he added, "Unfortunately, Mr. Administrator said that the hall, elevator, and safety staircase were all cleaned today. ”

Officer Takagi said, "Mr. Administrator didn't pay attention to the time when the person in the gray-black raincoat took the elevator upstairs and the time when the person in the gray-black raincoat came out of the safety staircase, but Mr. Administrator was very familiar with the rules of elevator operation, and he estimated that it was about seven minutes based on the time when the elevator was running." That's it. ”

Officer Nagasuke said: "Okay, the forensic personnel's speculation on the time of death of the deceased is between 6:45 and 7:15 in the morning, that is, around 7 o'clock in the morning, which is consistent with the situation of your investigation. ”……

After that, the room was ready, and the forensic personnel went to investigate the No. 2 elevator, although there was little hope, but they also had to check, and they couldn't let go of any suspicious places.

I found that the person's mood was much better and he could accept the questioning.

According to the investigation, the deceased's name was Hirotoshi Nakamoto, and it was found that the person was his colleague and fiancée Yui Shimura, because Hirotoshi Nakamoto did not go to work today, and no one answered the phone, so Yui Shimura came over during his lunch break, and after opening the door with the key, he found Hirotoshi Nakamoto lying in the entrance, and the screams provoked the neighbors, and the neighbors called the police.

Officer Sato asked, "So, Miss Shimura, do you know who Mr. Nakamoto has a grudge against?"

"Well, he's an easy person to make enemies. Yui Shimura said.

Officer Takagi was a little dumbfounded, such a person, you still want to marry him?

Officer Sato said, "There are some photo albums here, please find out who you think has a grudge against Mr. Nakamoto, Miss Shimura." ”

Soon after, Shimura found a stack of photos in the photo album.

Officer Takagi smacked his lips in a low voice, "So much?" and quickly shut up, this is not what should be said when handling a case.

Officer Sato asked, "Miss Shimura, if you were asked to choose one of these people, who would you think would have the greatest grudge against Mr. Hirotoshi Nakamoto?"

Officer Nagasuke praised, "That's a good question, Miss Shimura, let's pick one now." ”

"Well," Yui Shimura thought for a moment, picked out a photo of the two of them, and pointed to the person next to Hirotoshi Nakamoto and said, "That's this person, Akira Kato." ”

Judging from the photos, Mr. Kato and Mr. Nakamoto hook up and have a good relationship. Officer Sato asked, "Why Mr. Kato?"

"Well, he used to be my boyfriend. Shimura Yui said with a sigh of relief.

"Ah, then why are you ......" Officer Takagi didn't finish his sentence, feeling Officer Nagasuke's gaze, he immediately added, "If you don't want to talk about this question, you can leave it alone." ”

Shimura Yui hesitated for a moment and said: "This is actually nothing, he went abroad for three years, and at first there was contact, and then there was no contact, I thought he was empathetic and had another girlfriend, I was very miserable at the time, it was Guangjun who has been with me, so we dated." ”

Three years, empathy, three years, empathy......

Officer Takagi thought that he was going to go out for three years, and his head was a mess, no, it was all mush.

Yui Shimura said: "At the end of last year, Kato came back suddenly, and then came to me, and I finally rejected him, and I heard from Hirotoshi that Kato also came to him for a drink, but I don't know the specifics. ”

Officer Chosuke asked, "Miss Shimura, do you know Mr. Kato's contact information?"

Yui Shimura thought for a while and said, "I don't know about this, but I've seen him drive a private car." As he spoke, he reported the license plate number.

Chiba's car, Officer Takagi, was taken aback. ……
