Doomsday Bunker Upgrade

The arrival of Qin Lan and Ding Ning added a lot of popularity to Chen Xin's shelter.

After all, he was the only one at first. If he didn't speak or make a little noise, the entire refuge would be terribly silent.

Therefore, although the operation of the generator and the ground source heat pump will produce a lot of noise, Chen Xin has never considered noise cancellation or sound insulation, because the sound makes him feel that he is not living in a tomb, and he will not feel too much. Quiet and claustrophobic.

However, the arrival of Qin Lan and Ding Ning also had other effects on Chen Xin's life, at least now Chen Xin has to make three servings of breakfast.

"Ah Xin, do you want to eat this in the morning?" Ding Ning asked with a strange expression while watching Chen Xin making breakfast.

It wasn't that Ding Ning felt that the breakfast prepared by Chen Xin was not good, but that he was too extravagant.

Fresh rice is used to make porridge, which can also be said to be rice grown by Chen Xin himself, which is being picked up in the field, so it doesn't matter how you eat it.

But the thinly sliced ​​Iberian ham he put aside made Ding Ning feel a little unacceptable. Even before the disaster, few people would eat breakfast like this, which was really extravagant.

"You said this Iberian ham? It was sent by Xiaolong before. The quality of ham will decline after a long time, and I have already opened it, so I can't leave it for too long." Chen Xin explained, Seeing that the porridge in the pot was almost boiled, he turned off the stove and put the prepared breakfast on the table.

After setting up the breakfast, Ding Ning also brought the bowls and chopsticks, and the three sat down and ate breakfast together.

"It's so fragrant!" Although Ding Ning said that she felt extravagant, when a piece of ham entered her mouth, she couldn't help but let out a loud admiration.

Qin Lan wanted to appear a lot quieter. Anyway, when she was hospitalized before, Chen Xin's meals for sick patients included these every day. Although she still thought it was delicious, she didn't shout like Ding Ning.

But while eating breakfast, Qin Lan still asked Chen Xin: "A Xin, do you need us to help you with anything? Although we are here to protect you, it doesn't mean that we are here for nothing. Stay, if you need our help, just speak up."

Ding Ning, who was beside him, nodded his head quickly, and hurriedly echoed: "Yes, yes, if there is anything we can do, just say it, don't be like yesterday, the official result is just to let me water for you."

"There are indeed some things to talk about, but I have finished the relatively tedious and heavy work a few days ago, such as plowing, raising seedlings, and transplanting rice seedlings. If you came a few days ago, there would be many things to do." Chen Xin heard the two said they wanted to help, and after thinking for a while, he explained: "Now these few days are relatively easy, the rice in the field only needs to be watered, and the vegetables in the hydroponic tray basically don't need to be watered. Just let it grow on its own."

"But we can't do nothing, right? It feels like we're here to eat rice." Qin Lan still hopes that he can help Chen Xin to do what he can.

Seeing Qin Lan's insistence, Chen Xin thought about it and said, "If that's the case, then there is indeed something you can do for me, Lan."

"What's the matter?" Qin Lan suddenly looked forward to it.

Chen Xin smiled, tapped her bowl with chopsticks, and said, "Eat first, and then talk when you're done."

The breakfast was quickly finished. After Ding Ning took the initiative to help clean up the dishes, Chen Xin took the two to the oxygen generator in the shelter.

There are a total of five oxygen generators in Chen Xin's shelter. In addition to the one placed in the living room, there are also four placed next to the generator.

"This is the algae oxygen generator of the shelter, which is mainly used to provide oxygen here. Because it is a biological oxygen generator, the algae will leave a lot of sediment." Chen Xin raised his hand and tapped the green sediment at the bottom of the tank He introduced to Ding Ning and Qin Lan: "These sediments are all natural algae. The so-called healthy foods such as spirulina that were popular before the disaster were all similar to these. What I need your help is to put These sediments in the tank are fished out and fed into the biogas reactor as a raw material.”

After Chen Xin explained, Ding Ning and Qin Lan also understood what he wanted them to do.

Chen Xin took a bucket, put it next to a valve at the bottom of the oxygen generator, opened the valve a little bit and said, "This valve is prepared to extract these sediments, as long as the valve is opened, these sediments will be sucked by themselves. Come out, just pick it up with a bucket."

A large vat of dark green liquid soon filled the pail as the flow of water left in the valve carried the sediment out of the bottom of the oxygen generator.

The original dark sediment at the bottom of the oxygen generator on the side was also discharged a lot, and it looked a lot lighter.

Chen Xin closed the valve, poured the green liquid in the pail into another large pail, put the pail back on the bottom of the valve, and opened the valve again.

"Because the valve is only used for drainage, in this process, the sediment inside cannot be drained out very well at one time, so an oxygen generator needs to be put in about three times." While explaining his approach, Chen Xin tapped the large bucket next to it again: "Although there is a lot of sediment in the discharged water, it is mainly water, so it is necessary to filter in this large bucket, and use a filter to remove all the sediment inside. "

With that said, Chen Xin picked up a filter hanging on the side, fished it out of the bucket, and the filter immediately had a layer of green algae.

"Of course, you can also put the filter on the bucket, which will save you some trouble, but be careful not to get water everywhere." Chen Xin took out another bucket and scraped the algae on the filter. In the barrel, he handed the filter to Qin Lan: "Just put the filtered algae in this barrel, the biogas reaction tank is there, there is a sign, just open the lid and pour these things in, but the taste is relatively Chong, it's best to wear a mask when adding ingredients."

"Sounds complicated!" Ding Ning couldn't help but sigh.

"It's a bit cumbersome, so I'm thinking about how to transform it. It doesn't need to be so cumbersome, but I don't have any ideas for now." Chen Xin nodded. In fact, he himself thought it was quite troublesome, but he was not in a hurry to improve.

Qin Lan took the filter and tried to put it on the bucket to get the water directly, but it quickly filtered out a lot of green algae.

Turning her hands and pouring it into another bucket, she said, "Leave this to me, as long as you filter out all these algal deposits, right?"

Chen Xin nodded, pointed to the sediment at the bottom of the oxygen generator tank next to him and said, "Just fish out these sediments. After the bucket is full, go to the biogas reaction tank to add materials. You can have two people. Cooperate."

Qin Lan and Ding Ning both nodded their heads. This work just looks cumbersome. It is not very troublesome and tiring work. The two of them cooperate and can finish it quickly.

"After scooping up the sediment, you only need to open the water inlet valve next to you to add water to the oxygen generator. You don't need to add too much water. There is a scale on the jar, just add it to that position." After that, Chen Xin Then he turned around and walked towards the planting greenhouse, and Ding Ning and Qin Lan also began to cooperate to discharge the sediment in the oxygen generator.

While Chen Xin, Ding Ning, and Qin Lan were doing their respective jobs, the joint investigation team in the urban area was also holding a meeting to deploy the next steps.

"According to the clues we have at the moment, we still can't determine which sanctuary it is, so each sanctuary must do a good job of defense." In the conference room, a person who seemed to know that it was a high-ranking official was speaking. The others were also listening carefully to his speech.

After the high-ranking official finished speaking, a city bureau leader in a police uniform in front of the conference table also spoke: "Our city bureau attaches great importance to this operation, and has dispatched capable forces to cooperate with the comrades of the armed police force to conduct joint defense and coordination of various shelters. Control, checkpoints and defense facilities are set up at the entrance of each shelter to ensure that every person entering and leaving the shelter will be checked and will not bring dangerous items into the shelter.”

"Our armed police will also cooperate with the city bureau to ensure the safety of every shelter." An officer in an armed police uniform beside the city bureau leader also followed suit.

The high-ranking official presiding over the meeting nodded in satisfaction, but there was no expression on his face. These are basic things. If you do what you should do, if you don't do well, something goes wrong. Someone will lose their job, even in this special period. To lose my head.

Refuge No. 2 in Baling County was attacked before, and there was a vicious incident of suicide attack. The relevant personnel in charge of the management of Refuge No. 2 in Baling County and the management of the county government in Baling County were all punished. Yes, some people have even been held accountable, arrested and imprisoned, and they will be liquidated together after this incident is over.

"Defense alone is not enough, we have to attack! Next, let the comrades of the Municipal Bureau talk about the arrangement of the arrest operation." The senior official who presided over the meeting set the tone, turned his attention to the leader of the Municipal Bureau, and signaled him to speak.

The leaders of the city bureau introduced the arrest operation being arranged by the city bureau, and all the participants listened carefully.

Just in the corner, a city government official's eyes flickered while listening to the introduction of the city bureau leader, as if he was thinking about something.
