Ding Chen didn't wait until the evening to go back to the apartment, since it proved that the generator and charging system were working well, there was no need for him to stay here all the time, so he called it a day around three o'clock in the afternoon and went home.Because I was worried that the rain would damage the semiconductor components at night, I left only the waterwheel and the drive shaft in place, and brought back the generator and the transformer filter module.Carlo had been looking forward to Ding Chen's news all day, and when he heard that they were back, he immediately ran out of the building to inquire about the progress, seeing what she was looking forward to, Ding Chen simply moved the battery pack into the corridor and connected the lighting circuit on the first floor first.The lights that hadn't been lit in more than a decade came on, and the people who remained in the apartment let out enthusiastic cheers.The children ran through the hallways screaming, flipping switches one by one, and then chirping at the lights that were on or unresponsive overhead.Carlo stood in the doorway, smiling at the screaming and jumping children, and suddenly felt like crying.This is the bright light described in many stories, and she only vaguely remembers seeing it when she was very young, and she can't even tell whether it is a real memory or an imagination made up in her own brain.In the last few days of his stay in the power plant's duty building, Ding Chen also restored the power supply to the small building, but unfortunately there were few electrical appliances left, and all the rice cooker heaters could not be used, so there was no way to experience the convenience of the electrification era.But even so, Zheng Yu and Rogge have already learned the power of electric lights in advance, have seen the world, and behave much better than others at this time, at least remember to help Ding Chen unload all the things on the cart, and then send the cart back to its original place.Ding Chen observed the output current of the battery for a while, and after making sure that it had stabilized, he was relieved.The battery pack of the power plant has a large capacity and a good quality of a single cell, and after so many years, it can still work stably.But Ding Chen wasn't sure if it was a defect, there was no way to use these batteries as a power source when he came down from the mountain, and he was always there.Now to be used for daily power supply, it is necessary to ensure that the battery pack can work stably when unattended.When Ding Chen was in the army, he had systematically learned how to use daily materials to make explosives, and he dared to guarantee that the battery in front of him was definitely not on the list of explosives, but was often used as detonating or ignition equipment.So what he is most worried about is that these batteries will spontaneously combust under some kind of coupling conditions, and when the time comes, the apartment will be burned down, and everyone can join hands to return to nature.Ding Chen used a multimeter to measure the output voltage of each single section one by one, and calculated that the internal resistance and electromotive force were within the normal range, and no single section planned to take the initiative to change jobs, which was a little relieved.Then he walked over to Carlo, ready to tell her to keep an eye on the children and not touch the batteries.Here, he used twenty-four series battery packs, which were inverted into 220 volts of illuminated electricity with 48 volts of direct current.Although it is not possible to touch the AC output by mistake, considering that these children have been living in an era without electricity, they have no intuitive understanding of the danger of electric energy, so Ding Chen can't be careful.And although he only connected the power line on the first floor, he couldn't find the switch to cut off the wall outlet.In other words, all power supply sockets on the first floor are now electrified, which is also a safety hazard.If you think about it carefully, Ding Chen feels that his behavior of connecting the electricity is really reckless, and the apartment is not prepared at all, and it is completely the protagonist's aura protector if there is no accident.So he is going to let everyone have a good time after the electricity is cut off first, and wait for tomorrow after thoroughly checking the lines in the building, he brought down a roll of quilt from the mountain, because the packaging is complete, so the aging phenomenon is not obvious, Ding Chen is ready to directly use these wires to re-lay the power supply lines in the building.Carlo was still immersed in the excitement brought by the light, and did not notice Ding Chen's expression of gain and loss, seeing Ding Chen coming over, she jumped up and hugged Ding Chen and took the initiative to kiss him on the face.Ding Chen wiped his face embarrassedly, and then remembered that this cheap sister-in-law was still a big child, and it was only unreliable for her to restrain others.Fortunately, in addition to the children, he also has Zheng Yu and Rogge, two adults to rely on, but these two people went out to unload the car and have not come back yet.He let go of the excited Carlo, turned around and walked outside the building, ready to go to Zheng Yu and Rogge, but as soon as he walked to the door of the building, he looked up and saw a group of people standing in the courtyard, looking at him dumbfounded.Today, few adults stay in the building, the men go fishing and hunting, the elderly and children go to the fields to clean up the leaks, and the women in the prime of life go out to pick wild vegetables and fruits and other food to support the family.So when Ding Chen came back, there were only Carlo and a group of children left in the apartment who couldn't help, and a few old people who had better living conditions and didn't have to run around for their livelihoods.and two fighters who guarded the apartment.This is also the reason why after Ding Chen received the electricity, only a group of children celebrated, the old people always had to be reserved, and the soldiers were on the roof of the building, and it was impossible for them to run out to congratulate Ding Chen.But after Ding Chen finished testing the circuit, the fishing team led by Zhu Yu had already returned.The lake to the north of the apartment is large and full of fish.Especially this summer's torrential rain washed down a large amount of organic matter from the upstream, fattening the fish and shrimp in the lake, so Zhu Yu and his entourage had a lot of harvests.Normally, this kind of large-scale fishing before winter is not too much, because the shelf life of fish at room temperature is very short, and if you don't eat it quickly, you have to pickle it, which is definitely not economical considering the lack of salt in the apartment.So Zhu Yu took people to fish, just to familiarize himself with the craft, and wait until the temperature drops below zero, and then go, at that time, the harvested fish and shrimp can be directly frozen, and they will be eaten until the weather warms up in spring.So Zhu Yu and his entourage, who returned with a full load, not only came back ahead of schedule, but everyone was also very happy.Seeing that the living standard of the apartment is gradually improving, it is expected that it will soon return to the way Ye Dai's father was when he was alive, and everyone feels that the world is becoming better.When Ye Dai's father died, it hit the apartment quite hard, and the accidental explosion not only destroyed the entire farming industry in the apartment, but also several people who were very important to the apartment were injured and died one after another.Dad and others had to pin their hopes on a group of children like Ye Dai and Carlo.If someone had said at that time that the apartment would be able to recover in a few years, no one would have believed it.As a result, Zhu Yu and his companions happily walked to the vicinity of the apartment, and suddenly found that the night here seemed to be different from other places.At this time, the sunset has not yet dissipated, and there is still afterglow in the sky, so the lights on the first floor of the apartment do not look obvious.It's just that as soon as the caravan left, Zhu Yu and the others still retained a high level of vigilance, and they found out that something was wrong from a distance, and they immediately became nervous.There is nothing dangerous about fishing and shrimp, and it doesn't even require a lot of strength, so there are relatively few men in Zhu Yu's team, mainly young and middle-aged women and some half-sized children, and the actual combat effectiveness is not strong.After discovering that the light coming from the apartment was abnormal, Zhu Yu immediately stopped the team and brought two clever children to investigate.When the apartment lost power, he was already more than ten years old, and naturally understood what was happening in the apartment at a glance, and Zhu Yu was excited at that time, standing on the highway and staring blankly at the light shining from the apartment, he couldn't believe his eyes.The two children who were with him had never seen the electric light, and of course they didn't know why Zhu Yu was in a daze, and they were immediately frightened by the dazzling light in the building and Zhu Yu's appearance, and quickly ran back to move the rescuers.Ding Chen used the battery to power the operating room yesterday, and today it is not a secret that he went to the river to test the generator, a group of young and middle-aged women got together to do a day's work, and this matter naturally spread all over the sky, so from the children's mouths, they heard that the first floor of the apartment was as bright as daytime, and immediately someone guessed the truth, so everyone threw away the things in their hands, and they all ran back to see God, uh, wrong, it was to see a miracle.A group of people followed to the front of the building, just to see Ding Chen walking out of the door alone, the light behind him projected his shadow on the ground in front of the door, pulling out a long one, under the bright backlight, Ding Chen's face was blurred, the silhouette was clear, and it looked three-dimensional.The people who came from both directions were stunned for a moment, and then they didn't know who shouted, and the people outside the building suddenly hugged the door of the building, Ding Chen was taken aback, turned his head and ran, and said in his heart that everyone thinks this end of the world is not cruel enough, and the collective transfer to zombies aa2705221,,; mobile phone reading,
