Doomsday Bunker Upgrade

Pushing open the thick protective door that was originally closed, the small shelter that was closed before opened the door again.

Standing at the door, Chen Xin could still see some debris scattered on the ground, apparently left over from the previous evacuation.

"It looks like it needs a good cleaning." Although they haven't entered yet, the first impression of this small shelter for Chen Xin and Li Yulong is that it is a little dirty.

"After the people who originally lived here were evacuated because of the problem of oxygen supply, this shelter was temporarily sealed." The staff sent by the city government heard Chen Xin's evaluation and did not think anything was wrong. They just ordered it. Nodding to introduce the situation here: "This shelter was originally an underground parking lot, with two floors up and down each of 2,000 square meters. Because only the second underground floor meets the civil air defense standards, only this floor has been transformed into a shelter, designed to accommodate A thousand people."

"A thousand people? It sounds quite big!" Li Yulong walked in while listening to the introduction of the city government staff, and asked Chen Xin, "Brother Chen, do you think we can use such a large place? ?"

To this question, Chen Xin just shook his head and replied: "Not enough, 2,000 square meters is only more than three acres of land. If you are growing vegetables and fruits in a plantation, it is fine, but growing rice is not enough for this worker."

"The consumption isn't that big, right?" Li Yulong frowned when he heard Chen Xin say that, thinking that 2,000 square meters sounded quite big, and didn't understand why Chen Xin didn't say enough.

"The planting greenhouse in my shelter is 200 square meters. Calculated based on the yield of 1,200 catties per mu, if you grow rice, you can harvest 1,200 catties in three seasons a year. Three people can eat more, but four people are not enough. Do you still think that Is this place big?"

"Ah? Isn't it? Co-authoring a 2,000-square-meter area, the food grown is not enough for fifty people? Doesn't our country have super rice? Why is this amount enough?" Li Yulong seemed to be poured a basin of cold water. Feeling disheartened.

However, Chen Xin said with a smile: "Super rice can indeed yield 2,000 catties per mu, but it is very dependent on seeds and fertilizers. The seeds must be replaced a year after planting, otherwise the degradation will be very severe. Even if you can find someone to give them If you breed, the operating cost will be very high, so if you build a greenhouse just to grow rice, it’s just a waste of time and energy.”

Although Chen Xin said these words with a smile, the people around them who came down with them could hear the sarcasm in his words.

Because this matter also cooperated with the SWAT team, a team of SWAT officers will be stationed here to maintain law and order in addition to daily patrol tasks.

Chen Xin was a little selfish and persuaded Uncle Ding to send Qin Lan's team, so Qin Lan came here with them today to check the situation here and make some preparations for the SWAT team to be stationed in the future.

Hearing Chen Xin say this, Qin Lan frowned and asked, "But we have to plant grain! If we don't plant grain because we are in short supply, wouldn't everyone starve to death?"

"That's right, but Xiaolong's plantation is of course to give priority to obtaining economic value." Facing Qin Lan's question, Chen Xinchong gave her a comforting look before continuing to explain: "Of course, this is all It is based on the assumption that only one type of crop is grown. In the current environment and existing planting conditions, three-dimensional planting should be adopted, and the space utilization should be changed as much as possible to expand the planting area.

In this way, the planting area that can be used and the types of crops that can be planted are greatly increased. If the aquaponics system is used again, it can also provide aquatic products, and the output is more guaranteed. "

"Three-dimensional planting, aquaponics? How to do this?" Li Yulong immediately became excited when he heard Chen Xin's words, as if he wasn't the one who was disheartened just now.

"It's very simple. The ground is dug deep to make a pond for fish farming, the surface is covered with a planting board to grow rice, and then several layers of hydroponic planting layers are placed to grow vegetables and fruits." Chen Xin briefly explained a few words, looking at this empty refuge So, he asked Li Yulong: "Xiaolong, have you thought about how to plan here? It's impossible to use all 2,000 square meters for farming, right?"

"It's not impossible to use it for farming, right?" Li Yulong made a joke, but quickly said seriously: "I plan to allocate two-thirds of the area for planting, and the remaining one-third of the area will be renovated. as a residential area."

"That place will be a little crowded!" Chen Xin heard his arrangement, and already understood his plan, he said with a smile and said nothing more, just followed the staff of the city government to inspect the shelter. Happening.

Although this is only a small shelter, it was built according to the standard, and all the facilities are perfect.

Chen Xin followed the staff of the city government for a tour, and was very satisfied to see that the water and electricity facilities were still operating normally.

After introducing the interior of the shelter, the staff member talked about other supporting facilities: "After the disaster, the upper floor of the shelter was renovated, but only half of it was used as a coal-fired stack. "Because the interior of the shelter is heated by a boiler, the boiler is installed on the upper floor, so the coal is also piled on the upper floor."

"Can this boiler be removed? We installed a ground source heat pump, so there is no need to keep the boiler." Li Yulong heard Chen Xin and the city staff talking about heating equipment, and suddenly didn't want that old-fashioned coal-fired boiler.

However, Chen Xin shook his head and said: "Keep it, if there is any situation, when the ground source heat pump fails, there is a second set of emergency plans. Besides, the equipment can't be turned on forever, and it must be shut down. Repaired."

"Then I listen to you, Brother Chen, but it's too wasteful to use half of the area upstairs as a stack, isn't it?" Li Yulong nodded in agreement with Chen Xin's opinion, and at the same time asked his own doubts: "Brother Chen, what do you think about this? What's the arrangement?"

Facing Li Yulong's question, Chen Xin just smiled and patted his shoulder: "Why ask me when you already have ideas? The boss is you, do what you want."

After speaking, Chen Xin walked towards Qin Lan, and the two approached each other intimately, as if they were talking about something private.

Li Yulong watched Chen Xin and Qin Lan walk over to talk about their affairs, and shrugged indifferently, and continued with the staff of the city government: "If this is the case, then the boiler will not be dismantled, and the coal city government will still Can you supply?"

"There's no problem with this, but the city government will not supply it for free." Although the staff of the city government were a little confused about who said Chen Xin and Li Yulong, he would not be sloppy about his own work. Hearing Li Yulong When it came to coal supply, I immediately discussed the price with him.

Some people always say that the plot is bland, what do you want to watch... I don't want to watch this, I don't want to watch that, I'm very embarrassed

I don't want to write about murder and arson. If the dark side of society is written, it will be 404. Can't I just write about life and construction?
