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, and if he didn't speak and make a sound, the whole shelter would be quiet and terrifying.

Therefore, although the operation of generators and ground source heat pumps produces a lot of noise, Chen Xin has never considered canceling the noise or insulating it, because the sound makes him feel that he does not live in a tomb, and does not feel too quiet and fall into claustrophobia.

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

"Ah Xin, do you eat this in the morning?" Ding Ning watched Chen Xin make breakfast, and couldn't help but ask with a strange face.

It's not that Ding Ning thinks that the breakfast prepared by Chen Xin is not good, but that he thinks he is too extravagant.

Fresh rice porridge, this can also be said to be Chen Xin's own rice, and this kind of rice is being received in the field, it doesn't matter how you eat it.

But the Iberian ham that he put aside that had been sliced made Ding Ning feel a little unacceptable, even before the disaster, few people would eat breakfast like this, which was really a luxury.

"You say this Iberian ham? This is what Xiaolong sent before, and the quality of ham will decline after a long time, and I have opened it, so I can't put it for too long. Chen Xin explained, seeing that the porridge in the pot was almost boiled, so he turned off the stove and brought the breakfast that had been made to the table.

After setting the breakfast, Ding Ning also brought the dishes and chopsticks, and the three of them sat down to eat breakfast together.

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

Qin Lan was much quieter, anyway, when she was hospitalized before, Chen Xin sent these in the hospital meals every day, although she still thought it was delicious, but she didn't shout like Ding Ning.

However, while eating breakfast, Qin Lan still asked Chen Xin, "Ah Xin, do you need our help with anything?" Although we say that we are here to protect you, it is not to say that you eat and live in vain, and if you need our help, just ask. ”

Ding Ning on the side also nodded hurriedly, and hurriedly echoed: "Yes, yes, what can we do, just say, don't be like yesterday, the result is just let me help you water." ”

"If you want to talk about things, there are some things, but I have done the relatively tedious and heavy work a few days ago, such as plowing, raising seedlings, planting seedlings, etc., if you come a few days ago, there will be really busy things." Chen Xin heard the two of them say that they wanted to help, and after thinking for a while, he explained: "Now it is relatively easy these days, the rice in the field only needs to be watered, and the vegetables in the hydroponic tray are basically left alone, just let it grow on its own." ”

"But we can't do nothing, can we? It feels like we're here for rice. Qin Lan still hoped that she could help Chen Xin do what she could.

Seeing Qin Lan so insistent, Chen Xin thought for a while and said, "Since that's the case, then there is indeed something Ah Lan, you can help me do it." ”

"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 after eating." ”

——————————————

Breakfast was quickly eaten, and after Ding Ning took the initiative to help clean up the dishes and chopsticks, Chen Xin took the two of them to the oxygen concentrator in the shelter.

There were a total of five oxygen concentrators in Chen Xin's shelter, and in addition to the one placed in the living room, four were placed next to the generators.

"This is the algae oxygen concentrator in the shelter, which is mainly used to provide oxygen to my place. Because it is a biological oxygen concentrator, the algae will leave a lot of sediment. Chen Xin raised his hand and knocked on the green sediment at the bottom of the jar, and introduced to Ding Ning and Qin Lan: "These sediments are all pure natural algae, and the so-called health foods such as spirulina that were popular before the disaster are similar to these." All I need your help with is to remove the sediment from the tank and add it as raw material to the biogas reactor. ”

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

Chen Xin took a bucket and put it next to a valve at the bottom of the oxygen concentrator, opened the valve a little and said: "This valve is prepared for extracting these sediments, as long as the valve is opened, these deposits will be sucked out by themselves, as long as they are connected with a bucket." ”

As the flow of water left in the valve carried the sediment out of the bottom of the oxygen concentrator, a large vat of dark green liquid soon filled the pail.

The original dark sediment at the bottom of the oxygen concentrator on the side has also been discharged a lot, and it looks much lighter.

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

"Because the valve is only used to drain water, in this process, it is not possible to discharge all the sediment inside well, so an oxygen concentrator needs to be put about three times." While explaining his approach, Chen Xin knocked on the bucket next to him again: "Although there is a lot of sediment in the discharged water, it is mainly water, so it is necessary to filter it in this vat, and use a strainer to remove all the sediment inside." ”

As he spoke, Chen Xin picked up a filter hanging on the side, fished it out of the bucket, and the filter suddenly had an extra layer of green algae.

"Of course, you can also put the strainer on top of the bucket to save some trouble, but be careful not to get water all over the place." Chen Xin took out another bucket and scraped the algae on the filter screen into the bucket, and handed the filter to Qin Lan: "Just put the filtered algae in 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 more rushing, and it is best to wear a mask when adding." ”

"Sounds like a lot of work!" Ding Ning couldn't help but sigh.

"It's a bit cumbersome, so I'm thinking about how to renovate it, so it doesn't have to be so cumbersome, but I don't have any ideas for the time being." 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.

Qin Lan took the strainer and tried to put it on the bucket to directly connect the water, which quickly filtered out a lot of green algae.

Turning her hand into another bucket on the side, she said, "Leave it to me here, just filter out all this algae sediment, 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, and after the bucket is full, go to the biogas reactor to recharge, and you can cooperate with the two of you." ”

Qin Lan and Ding Ning both nodded, this work just looks tedious, it is not a very troublesome and tiring work, the two of them can cooperate and can be completed quickly.

"After fishing out the sediment, you only need to open the water inlet valve next to it, you can add water to the oxygen concentrator, the water does not need to be too full, there is a scale on the tank, and you can add it to that position." After speaking, Chen Xin turned around and walked towards the planting greenhouse, and Ding Ning and Qin Lan also began to cooperate to discharge all the sediment in the oxygen generator.

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

"According to the clues we have so far, the next target of this group of terrorists will be the 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." In the conference room, a person who seemed to know that it was a high-ranking official was speaking, and everyone else at the conference table was listening attentively to his speech.

After the senior official finished speaking, a city bureau leader wearing a police uniform at the conference table also spoke: "Our city bureau attaches great importance to this operation, and has dispatched capable forces to cooperate with comrades of the armed police force to carry out joint defense and control of various shelters, and checkpoints and defense facilities have been set up at the entrance of each shelter to ensure that every person entering and leaving the shelter will be checked and will not carry dangerous goods into the shelter." ”

"We, the armed police, will also do a good job of cooperating with the city bureau to ensure the safety of every shelter." Next to the leader of the city bureau, an officer wearing an armed police uniform also made a guarantee.

The senior official presiding over the meeting nodded with satisfaction, but there was no expression on his face, these are basic things, if they are done well, if they are not done well, if something happens, someone will lose their jobs, and even lose their heads in this special period.

The relevant personnel responsible for the management of the No. 2 Shelter in Baling County, as well as the management of the county government in Baling County, have all been punished, and some people have even been held accountable, arrested and imprisoned, and they are waiting for the end of this matter before they will be liquidated together.

"Defense alone is not enough, we still have to attack! Find out about these terrorists! Let the comrades of the city bureau talk about the arrangement of the arrest operation. The senior official presiding over the meeting set the tone, turned his attention to the leader of the city bureau, and motioned for him to speak.

The leader of the city bureau did not dare to slack off, cleared his throat and said: "After two large-scale investigations, we have now locked down the area of activity of the terrorists and are arranging the arrest ......."

The leaders of the city bureau introduced the arrest operation being arranged by the city bureau, and everyone attending the meeting listened very carefully.

It's just that in the corner, an official of the city government listened to the introduction of the city bureau leader, but his eyes flickered a little, as if he was thinking about something.
