On Saturday, March 24, March 24, near Chiba New Town, Chiba Prefecture, the experimental area of ​​Yinsha Vertical Farm Building.

Miko Miyamoto and her group first visited the Experimental Center Building. At Belinda's request, they also asked the computer center staff to operate all the systems.

"Solar energy system, oxygen regulation system, internal water collection and treatment system," Belinda asked, "Miko, are you a closed system?"

"Yes." Miko Miyamoto asked, "If you remove the soil and replace it with soilless cultivation, and then replace the cattle with humans, what can you think of?"

"This..." Belinda frowned.

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

"Dream," Enoch said, "It will cost about $500 million to send six people to space, not to mention building a city."

Anne said: "Although the cost is very high now, it does not mean that the technical reserves are not wrong in the future."

"There are two basic questions left." Miko Miyamoto said.

Belinda asked, "What's the problem?"

Miko Miko Miyamoto said: "The first is water. Plants need water to grow, and the water cannot be used in the plant during the growth period."

"Where is the second one?" Olivia asked.

Miko Miko said: "The second is to eat salt. When there are fewer people, it will be troublesome if there are too many people."

"This is indeed a problem," Anne said.

"I'll tell you, what's the point of calculating such a shadowless thing? Let's talk about it later." Enoch said.

Afterwards, Miko Miyamoto and his group left the building. Miko Miyamoto and Miko and Miyamoto got on two four-wheeled electric vehicles, walked around the experimental area and drove directly into the vertical farm building, and then stopped.

"Agricultural machinery should be used here, right? This car should be able to drive in," Enoch asked, "Is it the car broken?"

"People disinfect and change the internal volume to avoid bringing out bacteria in." Olivia said,

"It's right, get off the bus." Miko Miko said.

After disinfecting the group, they got on the four-wheeled electric car inside and entered the cattle farm where music was played. Anne asked, "Is this music for the cows? Can you give me one?"

"Of course." Miko Miko said.

Enoch pointed to a row of rooms of different colors and asked, "Those are places to raise cattle, right?"

"Yes, the double-digit door is a food trough." Miko Miyamoto said.

"Where is the order number?" Enoke asked.

"Cow dung." Miyamoto Ichiro said.

"Puff!" Everyone else laughed, making Enoke feel a little embarrassed, "Mr. Ichiro, we are allies."

"That's where cows come in and out." Miko Miyamoto drove the electric car into a double-digit door, and saw two rows of cow houses on the left and right sides, reaching far away, several workers were patrolling and inspecting with walkie-talkies.

Miko Miko Miyamoto said: "Each cow pen has a remote-controlled iron fence, which is usually open to facilitate cows to drink water. The water leads to each cow from the pipe above. When eating, close the iron fence, and then the feed processing yard uses a conveyor belt to deliver the processed feed from the ground and then to each cow."

"Next, press the switch and the cow can eat." Anne said, "a assembly line."

While speaking, the electric vehicle reached its head, and the conveyor belt gradually grew taller, and finally reached the top of the head. The electric vehicle passed under the conveyor belt, turned around and walked along the conveyor belt.

Enoch found a glass belt laying down the ground next to him and a conveyor belt below, so he asked, "What is this?" Then he reacted and said quickly, "Needless to say, I know what it is. This is the one who delivers cow dung."

Miyamoto Miko said: "There are nineteen areas here, each area has seven oxen granola doors, fourteen large cow houses, and a large cow house can be divided into ten small cattle houses, totaling 2,660. Each calf house can raise 100 beef cattle, but pregnant cows, calves and milk-producing cows, the cattle used for experiments need special care, so the plan is 200,000."

The electric vehicle turned around again and began to pass under the conveyor belt that was lowered from a short distance. The sight of the glass wall was a row of glass walls, and there was a circle of grass surrounded by metal railings to make the long runway.

Enoch changed the subject, "What is this for?"

"This should be a place for cattle exercise," said Olivia. "There should be a place for bathing and hoofing in front."

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

"These old men usually only have one and a half years of life, and then they are skinned and boned." Miko Miyamoto said a little heavy.

"That's it." Enoch sighed.

Anne's fork talks about it, "The last piece is a place to milk, right?"

Belinda asked, “Squeeze out the milk and send it directly to the processing site through the underground pipe?”

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

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

Afterwards, the electric car left the first floor and went up the second floor. The glass wall was in sight, and there were rows of neat plants behind it. 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 as going to the top floor." Miko Miyamoto said, and then said, "In order to prevent the insect eggs remaining in the soil from hatching and flying around, the floors above are completely closed."

"What should I do if the bug?" Enoch asked.

Miko Miko smiled and said, "Send animal soldiers to strangle, such as frogs." Then she said, "A layer of gases with high carbon dioxide content will be poured into the forage planting floors, using carbon dioxide to fatten, and gases with high oxygen content emitted from the forage floors will be input into the first layer."

"Carbon dioxide can indeed fatten, but it is very costly to do it in the open world," said Olivia.

After a while, the electric car went up to the twelfth floor, walked through two glass doors and entered, looking at the workers who managed the crops, as well as areas covered by plastic cloth, and some chickens strolling around.

"The reason is that the crop growth environment inside is different from that outside, so it is easy to adjust through lights," Miko Miyamoto said.

"Those trees are actually steel pillars, aren't they?" Anne asked.

Miko Miko smiled and said, "Yes, I can use steel here, so I can use steel."

Olivia said: "It's a good place, but it's not for me."

"Okay, the tour is over and I'll go back to have a meal." Enoch said...

Not long after, the Experimental Center Building and the private room in the restaurant.

The dishes were filled with the table, but one was covered. Enoch asked, "What is this?" and wanted to lift it up.

"Wait," Olivia held Enoch's hand and said with a smile, "You'll eat it when you open it."

"Uh..." Enoch found that Olivia's expression was a bit weird. He looked around and found that Miyamoto Ichiro had a expressionless face, while the others seemed to be gloating. So he had a bad premonition and looked at Anne.

"If I guess correctly, it's an earthworm." Annie smiled with her lips pursed.

"No?" Enoke exclaimed, "Get the earthworms raised in cow dung to eat?"

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

"No matter what, I don't want to swallow earthworms alive. I heard that there are parasites." Enoch said.

"No, I think it's familiar. We women are still resistant to eating alive earthworms." Anne asked with a smile, "Is that true, madam?"

"No, absolutely correct." Miko Miyamoto smiled, "I can't eat the earthworms even if I swallow them." As she said that, she opened the cover and revealed the vegetables inside, the earthworm tempura.

"It's almost the same." Enoch picked up an earthworm with chopsticks and ate it. "Well, it tastes good."

"In addition to farming and raising the fields, this thing is mainly made into feed." Miyamoto Miko picked up one and ate it. "Although it tastes good, the proportion of serving it on the table is not high."

After that, one person ate one, and the rest was wrapped in Enoke...

After lunch, the group went to the rooftop to take a bus and take a squid helicopter to the Ambina Doomsday Building in Kawagoe City, Saitama Prefecture.

The heavy shield helicopter stopped and released the bus. The bus continued to move forward. Olivia asked Belinda: "By the way, what's going on with the manned version of the heavy shield and the medical rescue version of the heavy shield that I asked you to develop?"

"Everything is under test," Belinda said, then asked Miko Miyamoto, "Do you want it?"

"No need, this kind of cargo can be loaded and cargo is suitable for me. For medical assistance, I will let a medical RV accompany the helicopter." Miko Miyamoto said.

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

"In order to defend against the aftermath of nuclear weapons, the Ambina Doomsday Building pilot area was built underground." Fujii Takako smiled.

Ji smiled and said, "Since it is not the doomsday, the management of things like garbage must comply with national rules. For convenience, this anaerobic digestion system was built on the ground, and the annual processing of 100,000 tons of urban domestic waste is the tax-free project we talked with the city. The doomsday building is underground. In the past, there were up to 504 civilian testers living there."

"How long have you lived?" Belinda asked.

"I lived for three months, completely closed, and I left a few days ago." Asai Ka said, "There are still some management researchers below."

Misa Horiuchi said: "There will be open to the public next Monday and the vertical farms will be sold out."

While talking, the bus entered a parking lot, then hovered down and stopped on a large square metal plate.

Ji got off the car and rang the visible doorbell on the pillar next to him, "Akui, it's me, my wife has arrived, open the door." Then he returned to the car and said, "That's Hinata Aoi, and she is responsible for both 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 replaced its position. Belinda asked, "Is this door only half a meter thick?"

"The original intention here is not to resist nuclear explosions, just block the aftermath and nuclear radiation." said Ji.

Enoch asked, "I have a question, what if the door and the door are stuck?"

"You can also climb stairs." Miko Miyamoto said.

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

"Yes." Ji Ji looked at Hinata Aoi who came to greet her outside and smiled, "If you want to let Akui explain in detail."

At this time, the platform stopped and everyone got off the car and saw Hinata Aoi. Hinata Aoi led them to visit.

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

The seismic system, water treatment system and air treatment system throughout the building, the main body of the facility is on the first and second floors, and the air treatment system can process oxygen and pour it into the oxygen cylinder; the main body of the biogas energy system, the main body of the facility is on the eleventh floor at the bottom, and only one biogas tank has been started.

There are also two non-doomsday systems, lifting platform and domestic waste delivery system. The metal platform stops next to the rooftop of the Doomsday Building. After Doomsday, you will have to climb the stairs.
