The arrival of Qin Lan and Ding Ning added a lot of popularity to Chen Xin's refuge.
After all, he was alone. If he didn't speak or make any noise, the entire shelter would be eerily silent.
Therefore, although the operation of generators and ground source heat pumps will produce a lot of noise, Chen Xin has never considered eliminating the noise or soundproofing it, because the sound makes him feel that he is not living in a tomb and does not feel too uncomfortable. Quiet and claustrophobic.
However, the arrival of Qin Lan and Ding Ning also had other impacts on Chen Xin's life. At least now Chen Xin has to make three portions of breakfast.
"A Xin, do you have this in the morning?" Ding Ning looked at Chen Xin making breakfast and couldn't help asking with a strange expression.
It wasn't that Ding Ning thought the breakfast prepared by Chen Xin was not good, but that he felt it was too extravagant.
Fresh rice is used to make porridge. This can be said to be the rice grown by Chen Xin himself. The fields are harvesting this kind of rice. 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. It really seemed very luxurious.
"You mean this Iberian ham? This was given by Xiaolong before. The quality of ham will deteriorate if it is stored for a long time, and I have already opened it, so it cannot be stored for too long." Chen Xin explained, Seeing that the porridge in the pot was almost done, he turned off the stove and put the prepared breakfast on the table.
After setting the breakfast table, Ding Ning also brought bowls and chopsticks, and then the three of them sat down to eat breakfast together.
"It smells so good!" Although Ding Ning said she felt luxurious, when a piece of ham entered her mouth, she couldn't help but sigh in admiration.
Qin Lan seemed to be much quieter. Anyway, when she was in the hospital, Chen Xin had these in the hospital meals that she sent every day. Although she still found them delicious, she didn't scream out like Ding Ning.
However, while eating breakfast, Qin Lan still asked Chen Xin: "A Xin, do you need our help with anything? Although we are here to protect you, we don't mean to say that we are here for free. Come on, if you need any help from us, just ask.”
Ding Ning on the side also nodded quickly and hurriedly echoed: "Yes, yes, if there is anything we can do, just say it. Don't be like yesterday, where you just asked me to water the water for you."
"There are indeed some things to do, but I have finished all the relatively tedious and heavy work in the past few days, such as plowing, raising seedlings, and transplanting rice seedlings. If you had come here in the past few days, you would have been busy." When Chen Xin heard the two people say that they wanted to help, he thought for a moment and then explained: "It's relatively easy these days. The rice in the field only needs watering, 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 just do nothing, right? It feels like we're here to eat free rice." Qin Lan still hopes that she can do something within her ability to help Chen Xin.
Seeing Qin Lan's insistence? Chen Xin thought for a while and said, "In that case, there is indeed something you can do for me, Alan."
"What's going on?" Qin Lan suddenly became excited.
Chen Xin smiled, tapped her bowl with chopsticks and said, "Eat first, and then talk after you finish."

Breakfast was finished quickly. After Ding Ning took the initiative to help clean up the dishes, Chen Xin took the two of them to the oxygen concentrator in the shelter.
There are a total of five oxygen concentrators in Chen Xin's shelter. In addition to the one placed in the living room, four more are placed next to the generator.
"This is the algae oxygen generator in the refuge. It is mainly used to provide oxygen for me. Because it is a biological oxygen generator? The algae will leave a lot of sediment." Chen Xin raised his hand and knocked on the green sediment at the bottom of the tank. Wu? 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 are similar to these. What I need your help is to These sediments in the tank are fished out and then added to the biogas reactor as raw material.”
After Chen Xin explained, Ding Ning and Qin Lan also understood what he wanted them to do.
Chen Xin took a bucket and placed it next to a valve at the bottom of the oxygen concentrator. He opened the valve and said, "This valve is designed to extract these sediments. As long as the valve is opened, these sediments will be absorbed by themselves." Come out? Just use a bucket to catch it. "
As the water flow left in the valve brought out the sediment at the bottom of the oxygen concentrator, there was soon a large bucket of dark green ** in the bucket.
And a lot of the originally dark sediment at the bottom of the oxygen concentrator nearby has also been discharged? It looks much lighter.
Chen Xin closed the valve, poured the green ** in the bucket into another large bucket aside, then placed the bucket back at the bottom of the valve and opened the valve again.
"Because the valve is only used for drainage, during this process, it is not possible to drain out all the sediment inside at one time, so an oxygen concentrator needs to be drained about three times." While explaining his approach, Chen Xin knocked on the big bucket next to him again: "Although there is a lot of sediment in the discharged water, it is mainly water, so it needs to be filtered in this big bucket and use a filter to remove all the sediment inside. "
As he spoke, Chen Xin picked up a filter hanging on the side and fished it out of the bucket. The filter suddenly became covered with a layer of green algae.
"Of course, you can also put the filter on top of the bucket. This will save you some trouble, but be careful not to get water everywhere." Chen Xin took out another bucket and scraped the algae off the filter. In the bucket, he handed the filter to Qin Lan: "Just put the filtered algae into this bucket. The biogas reaction tank is over there, there is a sign. You just need to open the lid and pour these things in, but the taste is worse. It’s best to wear a mask when adding ingredients.”
"It sounds quite complicated!" Ding Ning couldn't help but sigh.
"It's a bit cumbersome, so I'm thinking about how to modify it so that it doesn't have to be so cumbersome, but I don't have any ideas yet." Chen Xin nodded. In fact, he himself felt that it was quite troublesome to do this, but he was not in a hurry to improve it.
Qin Lan took the filter and tried to put it on the bucket to collect water directly. This quickly filtered out a lot of green algae.
Turning her hand and pouring it into another bucket aside, she said: "Leave it to me. I just need to filter out all these algae sediments, right?"
Chen Xin nodded, pointed to the sediment at the bottom of the oxygen concentrator tank next to him and said: "Just fish out these sediments. After the bucket is full, go to the biogas reactor tank to add materials. You can do it with two people." Cooperate."
Qin Lan and Ding Ning both nodded. This work just seemed a bit cumbersome. It was not a very troublesome or tiring job. The two of them could finish it quickly by working together.
"After removing the sediment, you only need to open the water inlet valve next to it 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 and walked towards the planting greenhouse, and Ding Ning and Qin Lan also began to cooperate to drain all the sediment from the oxygen concentrator.

While Chen Xin, Ding Ning, and Qin Lan were doing their own work, the joint investigation team in the urban area was also holding a meeting to plan the next move.
"According to the clues we have so far, the next target of this group of terrorists will be a shelter in the urban area, but it is not yet certain which shelter it is, so each shelter must do a good job of defense." Conference Room Inside, a man who looked like he was a senior official was speaking, and everyone else at the conference table was listening to his speech carefully.
After the senior official finished speaking, a municipal bureau leader wearing a police uniform in front of the conference table also spoke: "Our municipal bureau attaches great importance to this operation and has mobilized capable forces to cooperate with comrades from the armed police force to conduct joint defense and inspection of various shelters. For control, checkpoints and defense facilities are set up at the entrance of each shelter to ensure that everyone entering and exiting the shelter will be inspected and will not bring dangerous items into the shelter.”
"Our armed police will also cooperate with the municipal bureau to ensure the safety of every shelter." An officer wearing an armed police uniform next to the leader of the municipal bureau also gave assurance.
The senior official who presided over the meeting nodded with satisfaction, but there was no expression on his face. These are basic things. If you do it well, if something happens if you don't do it well, someone will lose their job, even in this special period. You're going to lose your head.
Baling County Shelter No. 2 was attacked before, and a suicide attack even occurred. The relevant personnel responsible for the management of Baling County Shelter No. 2, as well as the county government management of Baling County, were punished. Yes, some people have even been held accountable, arrested and imprisoned, and they are just waiting for this matter to be over before we can all settle the matter together.
"Defense alone is not enough, we have to attack! We need to find these terrorists! Let the comrades from the city bureau talk about the arrangements for the arrest operation." The senior official presiding over the meeting set the tone and turned his attention to He asked the leader of the municipal bureau and motioned for him to speak.
The leader of the city bureau did not dare to neglect, cleared his throat and said: "After two large-scale investigations, we have now locked down the terrorist activity area and are arranging arrest operations..."
The leader of the municipal bureau introduced the arrest operation being arranged by the municipal bureau, and everyone present listened attentively.
But in the corner, while listening to the introduction of the situation by the leader of the city bureau, a city government official's eyes flickered, as if he was thinking about something. (End of chapter)
