Detective Conan: The Grey Winged Angel

　　 Saturday, March 24th, in the morning, the harbor vice city center.

Tachibana Maori left the opening ceremony scene and entered the Toshin Odaiba Hotel when the 13 members of Maori and his party were busy lining up at the deputy capital of the harbor. In the temporary house built on the rooftop, I saw Miyamoto Ichiro and Miko Miyamoto, Belinda, Olivia, Annie, and Enoch, as well as Kohime, Asai Ka, Fujii Takako, Horiuchi Misa , Everyone is watching TV news around the table drinking drinks.

　　 After greetings, Tachibana sat down and Miko Miyamoto offered a cup of tea, "The draft is good."

　　 "Thank you, Madam." Tachibana Maiya said with a smile.

　　 "Miko, I just calculated it, but you made a big fortune." Olivia laughed.

　　 "How do you say?" Enoch asked.

　　 "The average land price here used to be about 10,000 yen per square meter, but now it's not much higher than ten times." Olivia laughed.

"What's the matter," said Miko Miyamoto. "There are more than 500 hectares here, which is only more than 500 billion yen when it doubles tenfold. When I bought this place, I spent 1.3 trillion yen. 300 billion yen was used as the exposition fund, plus construction costs and other expenses, and it cost nearly 2 trillion yen. It is still early to make a profit."

"I didn't say that you are profitable," Olivia laughed. "And it's not your calculation. What you bought is permanent land use rights, and you don't have to pay taxes for 50 years. From the current flow of people, the Expo In the end, you won’t lose much of your ticket income; these tourists will also bring you a lot of benefits in terms of transportation, hotels, retail, etc. You can recover most of the costs no matter what, and then just develop it enough."

　　 "Forget it, this thing is not clear." Miko Miyamoto shook his head and said.

　　 Olivia smiled and said, "Anyway, you have to admit that this fair has helped you make a fortune."

　　 "There is no doubt about this." Enoch laughed.

　　 "Okay, I admit it." Miko Miyamoto smiled.

　　 Enoch asked: "By the way, I have a question, Belinda, Olivia, Annie, why are you not participating in the exhibition?"

　　 "Are you taunting us?" Belinda asked angrily.

　　 "Belinda's steel, Olivia's transportation, and my oil," Annie laughed. "We are inherently opposed to green environmental protection, and participating in the exhibition will only make people question."

　　 Miko Miyamoto said: "That's good, but the factory is not environmentally friendly, and the state will not be soft when fines are imposed. We still need to do more research."

　　 "This is of course, but I think it's useless at all." Olivia said, "Only when the earth's plant coverage reaches a certain level, can it effectively curb global warming."

　　Anne said: “As far as I know, due to the mad cow disease, there are already many people in Brazil who are preparing to develop forests and pastures in the Amazon basin.”

　　 "This kind of thing has already happened, and the Brazilian government can't stop it," Enoch said.

　　 At this time, a heavy shield helicopter flew over, and Miko Miyamoto smiled and said, "Let's go, I will take you to see my ranch."

　　 A moment later, the heavy shield helicopter landed on the roof, and Miko Miyamoto and his party boarded the bus that came out of the cabin. ...

　　 Near Chiba New Town, Chiba Prefecture, the Indo Vertical Farm Building Experimental Zone.

The heavy shield helicopter stopped on the apron on the roof of a building and released the bus. Miko Miyamoto and his group got out of the car. Miko Miyamoto took Miyamoto Ichiro and walked to the railing first. He looked outside and laughed: "Vertical Farm Building. It's the behemoth in front of you."

　　 "Okay," Olivia laughed, "I now think that our habit of messing with money is all infected by you."

　　 "It must be." Belinda smiled.

　　 "There is no way to build it like this, but the operation cost is high if it is built." Miko Miyamoto said, "For example, farming, gas emission filtration and so on."

　　 "How big is this?" Annie asked.

"The vertical farm occupies an area of ​​about two square kilometers and is about 55 meters high. There are twelve floors inside, and each floor is about one meter deep. It was dug out during the construction of the subway and the Doomsday Building," said Ji Ji. "The surrounding buildings are a biogas system, a water treatment system, a meat processing plant, a dairy processing plant, a feed processing plant, and a warehouse. The place where we stand now is the roof of the Experimental Center Building, which is 120 meters high. Around, the one-piece suit covers an area of ​​about six hectares, with a computer center, a biological research center, a medical reproduction center, a hospital, a convenience store, a restaurant, and an apartment."

　　 Enoch asked: "I have a question. For such a big building, I won't talk about the lighting inside. It definitely doesn't. But it doesn't matter, but how about ventilation?"

　　 Horiuchi Misa said, "It depends on the fan. The rooftops are all that stuff."

　　 "I am interested in computer centers." Belinda asked, "Precision agriculture, right?"

"Yes, the computer center will collect and monitor data on the vertical experimental farm, monitoring the conditions in the vertical farm building, the temperature, humidity, and oxygen content of each floor; the body temperature, weight, eating, and excretion of each cow; The temperature and growth status of each piece of crops.” Tachibana Zhenye said, “Ventilation is managed according to the breathing and oxygen content of animals and plants, and the corresponding temperature, humidity, light brightness, etc. are adjusted according to the growth of livestock and crops. ."

　　 "This system is pretty good," Olivia said.

　　 "According to 600 square meters for 100 beef cattle, two square kilometers and 2 million square meters can house 300,000 beef cattle." Annie said.

　　 "Can you raise so much?" Enoch was surprised. "The twelfth floor is 3.6 million yuan. The vertical farm is really saving space."

　　 Horiuchi Misa smiled and said, "How can there be so many~www.readwn.com~The houses are trampled on."

　　 Asa Jinxiang smiled: "That's right, in that case, the cow dung can be piled higher than the mountain every day."

Ji Ji said: "Now there are 10,000 beef cattle on the first floor, and the eleventh floor upstairs is full of feed. The plan is to raise 200,000 beef cattle on the first floor, and then use cow dung to raise some earthworms and fungi. The ten floors upstairs are used to grow feed, supplemented with salt, minerals, etc., enough for the cows downstairs to eat. The first floor is used to grow food, vegetables and fruits, on the one hand for research, on the other hand for the people in the experimental area to eat. There are some free-range chickens on these eleven floors upstairs."

　　 "Self-sufficient," Enoch said.

"A cow can produce five to six tons of cow dung a year, and the biogas system needs to be able to process 4,000 tons of cow dung and other organic matter per day." Olivia said, "The electricity generated is enough for more than 20,000 households. After being connected to the grid, there will be a lot of benefits."

"Don't forget it, this farm is not worth building for a landlord like you," Belinda said. "And Japan has less than 50,000 square kilometers of land, and 20 square kilometers is 25%. One."

　　 "How much does it cost?" Olivia asked.

　　 "The number of people working in agriculture in our country is decreasing. If we discard other systems and build a small vertical farm in units of 1,000 square meters, it is meaningless." Miko Miyamoto said. "And mine, not counting the cost of the system development, and the cost of the soil between the floors, the construction cost is about one billion US dollars, if others estimate that the cost will not be recovered, and my catering industry can consume the beef, but it is just such a preliminary It is estimated that it will take at least ten years to recover the construction cost."

　　 "Forget it," Olivia said.

　　 "Let's go, take you to visit." Miko Miyamoto said. ...
