We Live In Nanjing

  Chapter 13 A Thousand Miles of Marriage

  The next day, Banxia woke up early in the morning, humming a song to pack things, and bounced around in the house.

  She is in a good mood.

  For breakfast, eat cabbage lotus seed porridge with purslane cold smoked venison shreds. The salted smoked venison tastes a bit hard, so it needs to be torn into thin shreds, and it tastes delicious with lotus seed wild vegetable porridge.

  Go out today! Going to complete a historic meeting! After the destruction of human civilization, the only remaining survivors met again for the first time.

If mankind can continue in the future, then today will be the day recorded in the annals of history—September 8 is the date when human civilization re-emerged. If there are still religions in the future world, then today is the seventh day of Genesis in the Bible. , Is when Moses led the tribe to separate the Red Sea in the book of Exodus. In the New Bible hundreds of years later, it will be recorded like this: As soon as the radio station is turned on in Pinellia, Maxwell uses electromagnetic waves to make the survivors know overnight and the city wakes up. , Mankind regained a new life.

  "You who fell from the sky, you fell on my horseback."

  Banxia is humming a song, carrying a bag in his hand, and all the equipment that needs to be carried with him are laid flat on the floor in turn, filling the living room.

  She counted them one by one.

There is a lighter and a firelighter. The lighter is a magnesium bar and a half saw blade. When igniting, use the saw blade to scrape the metal magnesium on the hay or paper to ignite the fire. This kind of lighter has a simple structure and is not afraid of water. .

   "The jade-like appearance, the clear water-like gaze, and the slight smile made my heart hot."

  This time, Pinellia put twice as much dry food in the backpack, and each piece of dry food was wrapped in plastic cloth. If the number of people here increases in the future, the food pressure will also increase.

  Fortunately, there is no shortage of food in Nanjing.

  "You who never look back, spread your wings!"

  "Looking for the direction, the direction is forward."

  The girl hummed a song and went downstairs step by step and opened the door of 703 downstairs.

  The house was empty, all the furniture was removed, and with the creaking sound of Pinellia opening the door, a small shaggy face came out of the bedroom.

   "Good morning, Uncle Huang." Banxia greeted him, "Isn't it disturbing you to sleep?"

  Uncle Huang was obviously accustomed to her. He curled up at the bedroom door, scratched his itching with his front foot, squinted his eyes and yawned.

This weasel has lived here for many years. When Banxia had an impression of it, Uncle Huang was the resident here. It lived in 703. Later, 703 was requisitioned by Banxia and the teacher as a power distribution room, and it was not used. Instead, he often brought food to him when he drove away. This weasel had a very comfortable life in his later years.

Pinellia backhand closed the door and stepped into the living room, carefully avoiding the white PVC pipe on the floor. All the debris in this household was cleaned out, only a huge metal shelf and a rusty silver The cabinet stands against the wall, and a whole wall of car batteries is placed on the shelf.

  A total of forty.

  Forty car batteries, dense black cables are connected from the batteries, and then shunted into dozens of white PVC pipes, going out through the floor-to-ceiling windows of the living room, looking spectacular.

Back then, the teacher took her and searched all the car batteries that were found to work here. From then on, all of their electricity relies on these forty car batteries. The voltage of one battery is 12 volts, and forty batteries are connected in series. , Is a high-voltage power supply of five hundred volts. This huge battery pack is connected to the silver cabinet next to the shelf. The cabinet is an EPS. The full name is emergency power supply system. It was found by the teacher from the nearby Nanjing Agricultural University Hospital. , It is essentially a frequency converter, which can invert a voltage of 500 volts into 220 volts.

  EPS and then go into the stairwell, 220 volt alternating current goes up the stairs and enters the 804 upstairs to supply power for the daily life of Banxia.

  There are three sets of wires connected to the battery pack, two sets of outputs and one set of inputs.

  Except for one set of EPS output lines, the other set of output lines do not pass through the EPS cabinet, but go out directly from the floor-to-ceiling windows, fall along the outer wall, and connect to the high-voltage power grid.

The high-voltage power grid is actually a fence, almost one person tall. It uses insulated wood as a support. A wooden rod with a thick bowl is erected every two to three meters. The entire 11 building of Zhongqinyuan is covered by a metal wire along the wooden support. circle it.

  The metal wire is a bare outdoor telephone wire with the outer skin stripped. It is a twisted pair of three copper wires and four steel wires. The steel wire guarantees strength and the copper wire guarantees conductivity. It is an excellent material for power grids.

There are six wires on the wooden support from top to bottom. The distance between each two wires is ten centimeters. They are insulated from each other and do not touch each other. One of them is connected to the positive pole, and the two to six are connected to the negative pole— Under normal circumstances, there is a clear separation between them, and there is nothing wrong with each other. The well water does not interfere with the river water. If an intruder touches the power grid and connects the adjacent positive and negative lines, the voltage of 500 volts can kill uninvited guests.

  Unlike many people imagine, the high-voltage power grid does not consume electricity when it is normally connected, because the positive and negative poles of this circuit are open. As long as nothing hits it, it will not consume much electricity if it is placed there for a year.

  What should I do if it rains?

   asked Pinellia.

  If it rains, won’t it conduct electricity?

  No, the teacher touched her head. As long as the voltage is not higher than one thousand volts, we don’t need to worry about rain.

The solar panel is responsible for charging the battery pack. The solar panel was removed from the street lamp by the teacher with Pinellia. After the human disappeared, the solar street lamp was still working. They turned on on time after dark, in this dead silence The unmanned city lights up all alone, like the souls left after the death of human civilization.

The solar panels are all hung on the outer wall of the balcony. They are not laid flat on the roof to prevent bird droppings. A solar panel has a voltage of more than ten volts. Just one solar panel is connected to a battery. It is quite simple and rude, but the design is simple. At the price of actual operation, they received a cramp in this messy cable.

  After the cables are connected, the room looks like a wire hole. In order to facilitate the arrangement, Banxia and the teacher put all the cables together and bundled them into white PVC plastic pipes to prevent mice from biting.

  Mouse thieves like to bite wires.

  This is why Banxia and the teacher want to leave Uncle Huang in 703. With Uncle Huang there, rats dare not be so rampant.

  Every two days and half of the summer, she would go down to check the power supply. She stopped for a long time in front of the battery pack, then squatted down and dragged out the gasoline generator under the shelf to remove the dust on it.

   "Uncle Huang, Uncle Huang, you said that if other people come here, let them live with you, okay?"

   Banxia turned her head and asked.

  Uncle Huang lay on the floor, with little black button-like eyes staring at her, two forelimbs covered with moist noses, his eyes were innocent.

   "Okay, okay, I won't drive you away." The girl chuckled, "There is no way to live here. Let them live in the opposite house."

  Uncle Huang tilted his head and didn’t know if he understood.

   Bai Yang yawned and came out of the room. Mom took the opportunity to enter the room and mopping the floor.

  She can only enter when Bai Yang comes out, so as not to see what she shouldn’t see.

  Papa sits on the edge of the table and brushes his headlines, the TV is on, and CCTV13 is playing the live news room. The anchor’s voice has always been the background music in this room:

"It is believed that our country will officially launch the sound search program next year. This is my country’s first exploration activity to actively search for extraterrestrial habitable planets and even alien civilizations. vitality…"

  Bai Yang sat down on the chair, took a sip of water, pointed to the screen on the TV and said, “If only we had such a big antenna, wouldn’t it be so exciting to use it for radio communication?”

  Papa raised his head and glanced, "That's FAST, radio telescope."

   "Then can it be launched?"

  "It can only receive, not transmit." Dad said, "This cauldron can hear aliens whispering, using it for amateur radio, it's a violent thing, you stayed up late last night to play radio again, right?"

  Bai Yang turned to look at his mother and nodded quietly.

   "How's the situation?"

   "There is one, that is the black station that I mentioned to you last time. I contacted her again, but it is not the black station." Bai Yang replied, "BG4MSR."

  "BG4MSR?" Dad frowned.

   "Her call sign."

The old man tried his best to remember, and then shook his head, "I haven't heard this call sign. Could it be someone who has recently tested it...recently, CRAC hasn't held an exam, right? Alas, I don't know too much. I have removed the mental retardation spectrum. "

   "I also unloaded the mentally retarded spectrum."

"Why?"

"I can't open it again." Bai Yang said, "Don't talk about it, dad, give me an idea. BG4MSR asks my eyeballs. At 6 o'clock this afternoon, I will meet at the intersection of Mufuyuan Street and Zhongshanmen Road. What should I do? ?"

  Looking back now, Bai Yang didn't know why he just agreed to her. The promise was neat and tidy, but he tossed and turned all night and couldn't sleep peacefully.

  This is probably the entanglement of innocent boys?

   Bai Yang thought so.

   "Oh?" The old man was very indifferent, "She is also from Nanjing?"

  White Yang nodded.

  "That's good, just go. Toads often meet offline. You can exchange skills." The old man was not surprised, "Do you know how my mother and I met?"

  "How did you meet?" Bai Yang was taken aback, wondering if it was because of a thousand miles of marriage that he did not hold? Relying on the radio station?

   "I met on a blind date."

  White poplar:...

"I mean, you don't have to be like me." Father explained, "I was in the army back then. I had no conditions, no way, but blind dates. If I didn't have any way, I could only go on a blind date. I can Like your mother..."

   "What's wrong with me?" My mother ghostly probed from the bedroom, and the indoor temperature dropped by five degrees.

   "...marry a perfect and outstanding woman like your mother?" Dad said.

   Mother gave a cold snort, then retracted again.

  Master both breathed a sigh of relief.

"Yang!" Mom shouted in the bedroom, "I have no objection to who you meet, you can go if you want to go, but you have to finish all the math papers you sent me today! Teacher Liu emphasized in the group I’m going to comment tomorrow!"

   Bai Yang sighed. Before he arrives at 6 o'clock this afternoon, he still has a mountain of books that can crush people to death.

  Is there anything more difficult than this in the world?
