Saturday, March 24, morning, near Chiba New Town, Chiba Prefecture, Inhan Vertical Farm Building Experimental Area.

Mimiko Miyamoto and her entourage first visited the experimental center building, and at Belinda's request, they also asked the staff of the computer center to operate all the systems.

"The solar system, the oxygen conditioning system, the internal water collection and treatment system," Belinda asked, "Miko, are you a closed system?"

"Yes. Miyamoto asked, "What can you think of if you could get rid of the soil and replace it with soilless cultivation, and then replace the cow with a human being?"

"This ......," Belinda frowned.

"Space City. Olivia laughed, "If the plants produce enough oxygen per unit of time, we can build a space city that can accommodate many people." ”

"Dream on. Enoch said, "It's about $500 million to send six people into space, not to mention building a city." ”

Anne said: "Although the cost is high now, it does not mean that there is nothing wrong with technical reserves in the future. ”

"There are two basic questions. Miyamoto said.

Belinda asked, "What's the problem?"

Miyamoto says, "The first is water, which is needed for plants to grow, and water is not available in plants during the growing season. ”

"What about the second one?" asked Olivia.

Miyamoto Miko said: "The second is edible salt, which you can't see when there are few people, and when there are too many people, it will be troublesome." ”

"That's really the problem. Anne said.

"I said you, what is there to calculate about this kind of shadowless thing, let's talk about it later. Enoch said.

After that, Miyako Miyamoto and her entourage walked out of the building, and Miyamoto Miko and five people got on two four-wheeled electric vehicles, drove directly into the vertical farm building after turning around the experimental area, and then stopped.

"This car should be able to drive in, right?" Enoch asked, "Is it broken?"

"Personnel are disinfected and the internal volume is changed so as not to bring in germs from the outside. Olivia said,

"That's right, get out of the car. Miyamoto said.

After the group disinfected, they got on the four-wheeled electric car inside, and then entered the cattle farm with music, and Anne asked, "Is this music for the cows?

"Absolutely. Miyamoto said.

Enoch pointed to a row of differently colored rooms and asked, "Those are the places where the cattle are raised, right?"

"Yes, the double door is a trough. Miyamoto said.

"What about the tracking number?" Enoch asked.

"Cow dung. Ichiro Miyamoto said.

"Poof!" the others laughed, embarrassing Enoch, "Mr. Ichiro, we're allies. ”

"That's where the cows come in and out. Miyamoto Miko drove the electric car into a double gate, and the cowshed with cattle in the left and right rows stretched out into the distance, and several workers were patrolling with walkie-talkies.

Miyamoto said: "Each stall has a remote-controlled iron fence, which is usually open so that the cows can drink water, and the water is piped from above to each cow. When it is time to eat, the iron fence is closed, and then the processed feed is brought in from the ground by conveyor belts at the feed processing yard and then to each cow. ”

"Then flip the switch and the cow will be able to eat. Anne said, "An assembly line." ”

As he spoke, the electric car drove to the end, the conveyor belt gradually became higher, and finally to the top of the head, the electric car passed under the conveyor belt, turned and walked along the conveyor belt.

Enoch noticed a glass belt laid on the ground next to it, and a conveyor belt underneath, so he asked, "What is this?" and then quickly said, "Needless to say, I know what it is, this is for cow dung." ”

Miyamoto Miyako said: "There are nineteen areas here, each area has seven cowsheds, fourteen large cowsheds, and one large cowshed can be divided into ten calf sheds, a total of 2,660, and each calf shed can raise 100 beef cattle, but pregnant cows, calves and lactating cows, the experimental cattle need special care, so the plan is 200,000 heads." ”

The electric car turns again and passes under the conveyor belt, which has begun to lower a short distance away, and is greeted by a row of glass walls with a long track of grass surrounded by metal railings.

Enoch digressed, "What is this for?"

"This should be the place for cattle to exercise. Olivia said, "There should be a shower and hoof trim in front of you." ”

"Take a bath and massage, this is serving the uncle. Enoch sighed.

"These uncles usually only have a year and a half to live, and then they are skinned and deboned. Miyamoto Miko said with some heaviness.

"That's right. Enoch sighed.

Anne diverted the topic, "The last place is where the cows are milked, right?"

Belinda asked, "The milk is squeezed through an underground pipe and sent directly to the processing plant?"

"Yes. Miyamoto asked, "Do you want to try it?"

"Forget it, let's go up. Enoch said.

After that, the electric car went out of the first floor and went up to the second floor, and there was a glass wall in front of it, and behind it were rows of neat plants, Miyamoto Miko did not stop the electric car, but continued to drive up, Enoch asked, "Why don't you go in?"

"It's the same when you go to the top floor. Miyamoto said, then continued, "In order to prevent the eggs from the soil from hatching and the insects from flying, the upper floors are completely closed. ”

"What about the bugs?" Enoch asked.

Miyamoto Miko smiled: "Send animal soldiers to strangle, such as frogs." He continued, "The gas with high carbon dioxide content from the first floor is poured into the grass floor, and the carbon dioxide is used to fertilize it, while the gas with high oxygen content from the grass floor is fed back into the first floor. ”

"CO2 can indeed fertilize it, but it's expensive to do in the open air. Olivia said.

Moments later, the electric car went up to the twelfth floor and entered through two glass doors to see workers tending to crops, patches of plastic-sheeted areas, and a few chickens roaming around.

"It's covered because the crops inside are grown in a different environment than the outside, and it's easy to adjust through the lighting. Miyamoto said.

"Are those trees actually pillars of steel?" asked Anne.

Miyamoto Miko smiled: "Yes, I can also use steel on my side." ”

"It's a nice place, but it's not for me," Olivia said. ”

"Okay, after the tour, go back to dinner. Enoch said. ……

Soon after, the Experimental Center Building, a private room in the restaurant.

A table filled the table, but one was covered, and Enoch asked, "What is this?" as he tried to open it.

"Wait a minute," Olivia said with a smile as she pressed Enoch's hand, "and you're going to eat it." ”

"Uh......" Enoch noticed that Olivia's expression was a little weird, looked around, and found that Ichiro Miyamoto was expressionless, while everyone else seemed to be a little gloating, so he had a bad premonition, so he looked at Anne.

"If I'm not mistaken, it's an earthworm. Anne pursed her lips and laughed.

"Isn't it?" Enoch exclaimed, "earthworms raised from cow dung to eat?"

"Cat excrement can also grind coffee. Belinda said angrily, "Earthworms are rich in protein, carbohydrates, fats, minerals, and water, and when there is nothing to eat, earthworms are a very good life-saving food." ”

"Anyway, I don't want to eat live earthworms, I've heard that there are parasites. Enoch said.

"No, I think it's cooked, and we women are still resistant to swallowing live earthworms. Anne smiled and asked, "Is that so, ma'am?"

"Yes, exactly. Miyamoto Miko smiled, "I can't eat live earthworms." As he spoke, he opened the hood and revealed the dish inside, earthworm tempura.

"That's pretty much it. Enoch picked up an earthworm with chopsticks and ate it, "Well, it tastes good." ”

"In addition to cultivating the fields, this thing is mainly made into fodder. Mimiko Miyamoto sandwiched one and ate it, "Although it tastes good, in general, the proportion of it served on the table is not high." ”

After that, one person ate one, and the rest was wrapped for Enoch. ……

After lunch, the group went to the rooftop to take a bus to take a heavy shield helicopter to Masugata Town, Kawagoe City, Saitama Prefecture, and the Abina Doom Building.

The Heavy Shield helicopter stopped on the tarmac and released the bus, and as the bus moved on, Olivia asked Belinda, "By the way, how about the manned version of the Heavy Shield and the Medical Rescue Heavy Shield that I asked you to develop?"

"It's all in the test. Belinda said, then asked Miyamoto Miko, "Do you want it?"

"No, this kind of cargo can be loaded with both trucks and cargo, and for medical care, I have a medical RV with a helicopter. Miyamoto said.

"Well, I have a question," Enoch asked, "where is the mansion?"

"In order to defend against the aftermath of the nuclear shock, the Ambinai Doomsday Tower test area was built underground. Takako Fujii smiled.

Jiji smiled: "Since it is not the end of the world, the management of things such as garbage must abide by national rules, and for the sake of convenience, this anaerobic digestion system has been built on the ground, which can process 100,000 tons of municipal solid waste per year, which is a tax-free project that we discussed with the city." Underneath is the Doomsday Building, which used to house up to five hundred and four civilian testers. ”

"How long?" Belinda asked.

"Stayed for three months, fully enclosed, and only left a few days ago. "There are still some management researchers down there. ”

Misa Horiuchi said, "Next Monday, this and the vertical farm will be open to the public, and the advance tickets are already sold out. ”

As he spoke, the bus entered a parking lot, then spiraled downwards and stopped on a large square metal plate.

Jiong-hee got out of the car and rang the visible doorbell on the pillar next to her, "Ah Kui, it's me, Madame arrived, open the door." Then he returned to the car and said, "That's Hyuga Aoba, and she's in charge of the vertical farm and here." ”

At this time, the large metal plate sank, and it turned out to be a lifting platform, and another metal plate took its place, Belinda asked, "Is this door only half a meter thick?"

"The original intention here is not to resist the nuclear explosion, as long as the aftermath and nuclear radiation are blocked. Jio Ji said.

Enoch asked, "I have a question, what if this place and the door get stuck?"

"It was also possible to climb the stairs. Miyamoto said.

Olivia asked, "We were in part of the ventilation system, right?"

"Yes. Jionghime looked at Hinata Aoi who came to greet her outside and smiled, "Let Aoi explain the specifics." ”

At this time, the platform stopped, and everyone got out of the car and saw Hinata Aoi, who led them to take a tour.

The main body of the Doomsday Building covers an area of one hectare, with the deepest part 60 meters above the surface and the top floor 5 meters above the surface, and is a 55-meter-long cuboid that is mainly maintained by four systems.

The seismic system, water treatment system and air treatment system throughout the building, the main body of the facility on the first and second floors, the air handling system can process oxygen and pour oxygen into the oxygen cylinders, and the biogas energy system, the main body of the facility is on the bottom 11th floor, and only one biogas digester is currently activated.

There are also two non-apocalyptic systems, a lifting platform and a household waste conveyor system, and the metal platform stops next to the top roof of the Doomsday Building, where the stairs will be climbed after the apocalypse.

The interior of the Doomsday Building is divided into four departments and eleven floors, which are ascended and ascended by two stairs and two elevators.

The first and second floors are the management department, the first floor has a general hospital, a gymnasium, a public bathroom, a maintenance center, a reception center or isolation center, and the second floor has a control center, a warehouse, a security room, a multi-purpose venue, and a research institute. In addition, the first and second floors will be cultivated in the open space using soilless cultivation for the cultivation of Chinese medicinal herbs.

The third to eighth floors are the living department, every two floors are counted as a part, the upper floor is the residence, a total of one hundred and sixty-eight rooms, one row of twenty rooms on each side, four rows of sixteen rooms in the middle, each room has a floor area of about five times eleven fifty-five square meters, with kitchen utensils and a bathroom with a toilet, through the stairs of the room to the lower floor, the lower floor is a self-reserved land, four meters high, there are about thirty-seven square meters of soilless cultivation area, four one by eight, one by five.

Soilless cultivation has a special drip irrigation cabinet that can adjust the height of the layer, the drip irrigation pipe is in the shelf, planting low crops, in 30 centimeters, you can plant 12 groups per unit area, plus do not consider the spacing, the planting area can also be increased by four to five times, enough to feed one person. The nutrient solution will be received at the hospital or research institute, and of course it will be bought after the end of the day.

The ninth and tenth floors are the breeding department, and part of the ninth floor is the grain and feed processing plant and the meat processing plant, and the chickens are raised in the low places to lay eggs and produce meat, and the high places are soilless to grow grain. The tenth floor is divided into three areas, the first area is a dairy processing plant, and cattle are used to produce milk, the second area is low-level earthworms and fungi, etc., the high tank is used to cultivate aquatic products, and the third area is soilless cultivation to grow grain.

The eleventh layer is the Ministry of Energy, which has a backup thermal power system in addition to the biogas system. There is also a fertilizer processing plant, which processes the fertilizer produced by the biogas system into a nutrient solution, and a backup warehouse, which stores 100,000 tons of war rations that can be shelf-guaranteed for 50 years, which can be used by 5,000 people for 50 years according to the amount of one kilogram of material per person a day. In addition, the excess household garbage from the Doomsday Building will be delivered to the ground after being transported here. ……

"Ah, that's five thousand people here. Enoch asked, "Is that paper enough?"

"You can use the leaves of the plant. Hinata said, "Excluding medical conditions, all of them are working well and can accommodate more than 7,000 people, and if you use oxygen tanks and biochemical suits to go out and collect more foreign capital, then more people can live." ”

Enoch asked, "With those guns in the security room, can you go out and grab something?"

"This is not America, and those guns are enough as a deterrent," Anne said. ”

"The hand crossbows in the pits are the main weapons, and the crossbow arrows can be recycled and reused. Belinda said.

Olivia smiled and asked, "The control center can cut off the water and electricity of any household, if it is the end of the world, how can the water and electricity of this rental property be collected?"

"The idea is to use energy as currency, and every household has a hand-cranked generator, and these batteries can be used on the surface, and the value of a fully charged battery depends on the situation at the time. "And redistribution is through work, and it takes a lot of people to run here without machinery." ”

"What about pensions?" Enoch asked with a smile.

"If there is enough manpower and enough Chinese medicinal materials and food can be grown, there will be no problem at all to give free use to the elderly who have worked for a certain number of years at that time. Hinata Aoi smiled.

"Not bad. Mimiko Miyamoto nodded and smiled.

"Thank you, ma'am. Hinata Aoi smiled.

Miyamoto Miko asked, "By the way, how about the five hundred and four people who lived here for three months?"

Hinata Aoi smiled: "It's very effective, it was five hundred and four people when I came in, and it increased by half when I went out." ”

"What do you mean?" Enoch asked.

Olivia laughed, "You big idiot, you and Anne have been here for three months. ”

"This kind of thing, it's not going to work for the time being. Anne said blushing.

Seeing that Enoch still didn't understand, Belinda smiled: "Get married and have children." ”

"Oh, I see. Enoch smiled awkwardly.

Olivia laughed: "This is a good way to increase the population, but the cost is a little higher." ”

At this time, the walkie-talkie in Hinata Aoi's hand rang, "Director Hinata, the secretary of the minister called to find the minister, and there was a 6.7-magnitude earthquake in the Shikoku Yunyu area just now, at 3:27 p.m. ”

"It looks like the fun time is over. Miyamoto said.

"Let's go back together. Belinda said. ……
