Chapter 13: A Thousand Miles of Marriage
The next day, Banxia got up early, hummed a song, packed her things, and jumped around the house.
She is in a good mood.
For breakfast, I had cabbage and lotus seed porridge with purslane and cold smoked venison shreds. The smoked venison marinated with salt had a bit of a hard texture, so it had to be torn into thin shreds and paired with lotus seed and wild vegetable porridge to make it taste delicious.
I'm going out today! I'm going to have a historic meeting! After the destruction of human civilization, the remaining survivors meet again for the first time.
If human beings can continue in the future, then today will surely be a day that goes down in history - September 8, the date when human civilization begins again. If there is still religion in the future world, then today is the seventh day of Genesis in the Bible, when Moses led his people to part the Red Sea in the Book of Exodus. Hundreds of years later, the New Bible will record this: As soon as Banxia turned on the radio, Maxwell used electromagnetic waves to let the survivors know overnight, the city revived, and human beings were reborn.
"You fell from the sky and landed on my horse."
Banxia was humming a song, carrying a bag in her hand. All the equipment she needed to carry with her was spread out on the floor, filling up the entire living room.
She counted them one by one.
There are lighters and also fire starters. The fire starter is a magnesium strip and half a saw blade. When igniting, use the saw blade to scrape the metal magnesium onto hay or paper to ignite the fire. This kind of fire starter has a simple structure and is not afraid of water.
"Her jade-like appearance, eyes as clear as water, and a slight smile that warms my heart."
This time, Banxia put twice the amount of dry food into her backpack and wrapped each piece of dry food with plastic cloth. If the number of people here increases in the future, the food pressure will also increase.
Fortunately, there is never a shortage of food in Nanjing.
"You who don't even look back, spread your wings!"
"Looking for the direction, the direction is ahead."
The girl hummed a song as she walked down the stairs and opened the door of room 703 downstairs.
The house was empty; all the furniture had been moved away. With the creaky sound of Banxia opening the door, a furry little pointed face poked out from the bedroom.
"Good morning, Mr. Huang." Banxia greeted it, "Did I disturb your sleep?"
Uncle Huang was obviously used to her. He curled up at the bedroom door, scratched himself with his front paws, squinted his eyes and yawned.
This weasel has lived here for many years. When Banxia had an impression of it, Grandpa Huang was already a resident here. It lived in 703. Later, 703 was requisitioned as a distribution room by Banxia and the teacher, but they did not drive it away. Instead, they often brought food to it. The weasel lived a very comfortable life in his later years.
Banxia closed the door with her backhand and stepped into the living room, carefully avoiding the white PVC pipes on the floor. All the debris in this household had been cleared out, leaving only a huge metal shelf and a rusty silver cabinet standing against the wall, with a whole wall of car batteries on the shelf.
There are forty in total.
Forty car batteries, with densely packed black cables connected to the batteries, then branched into dozens of white PVC pipes and flowing out of the floor-to-ceiling windows in the living room, looked spectacular.
At that time, the teacher took her and brought all the usable car batteries they found here. From then on, all their electricity relied on these forty car batteries. The voltage of one battery is 12 volts. When forty batteries are connected in series, it becomes a 500-volt high-voltage power supply. This huge battery pack is connected to the silver cabinet next to the shelf. The cabinet is an EPS, the full name of which is Emergency Power Supply System. The teacher found it in the nearby Nanjing Agricultural University Hospital. It is essentially a frequency converter that can convert 500 volts into 220 volts.
The EPS then goes into the stairwell, and the 220-volt AC power goes up the stairs and into 804 upstairs, providing power for Banxia's daily life.
There are three sets of wires connected to the battery pack, two output sets and one set of input.
In addition to one set of wires for outputting EPS, another set of output wires does not pass through the EPS cabinet, but goes directly out of the floor-to-ceiling window, falls along the outer wall, and is connected to the high-voltage power grid.
The high-voltage power grid is actually a fence, about one person tall, with insulating wood as the support. A wooden stick as thick as a bowl is erected every two or three meters, and metal wires are used along the wooden supports to encircle the entire building 11 of Zhongqinyuan.
The metal wire is the bare outdoor telephone wire with the outer sheath peeled off. It is a twisted pair of wires made of three copper wires and four steel wires. The steel wire ensures strength and the copper wire ensures conductivity. It is an excellent material for making power grids.
There are a total of six wires on the wooden support from top to bottom, with a distance of ten centimeters between every two wires. They are insulated and do not touch each other. One, three and five are connected to the positive pole, and two, four and six are connected to the negative pole. Under normal circumstances, they are clearly distinguished from each other and live in peace. If an intruder touches the power grid and connects the adjacent positive and negative lines, the 500-volt voltage will kill the uninvited guest.
Contrary to what many people imagine, the high-voltage power grid does not consume electricity when it is normally connected, because the positive and negative poles of the circuit are open. As long as nothing hits it, it will not consume much electricity even if it is there for a year.
What to do if it rains?
Banxia asked.
Won't it conduct electricity when it rains?
No, the teacher patted her head, as long as the voltage is not higher than one thousand volts, we don’t have to worry about the rain problem.
The solar panels are responsible for charging the battery packs. The solar panels were removed from the street lamps by the teacher and Banxia. After humans disappeared, the solar street lights were still working. They lit up on time after dark, and lit up alone in this dead and deserted city, like the souls left after the death of human civilization.
All the solar panels are hung on the outer wall of the balcony. They are not laid flat on the roof to prevent bird droppings. Each solar panel has a voltage of more than ten volts, and each solar panel is connected to a battery. It is quite simple and crude, but the simplicity in design comes at the price of actual operation. Their hands were cramped from connecting the tangled cables.
After the cables were connected, the room looked like a Pansi Cave. To make it easier to organize, Banxia and the teacher sorted all the cables and bundled them into white PVC plastic tubes to prevent them from being bitten by mice.
Rat thieves love to chew on electrical wires.
This is why Banxia and the teacher wanted to keep Grandpa Huang in 703. With Grandpa Huang around, the rats wouldn’t dare to run rampant.
Every two days, Banxia would come down to check the power supply. She would stop in front of the battery pack for a long time, then squat down to drag out the gasoline generator from under the shelf and brush off the dust on it.
"Uncle Huang, Uncle Huang, if other people come here, would you mind letting them stay at your place?"
Banxia turned her head and asked.
Grandpa Huang lay on the floor, staring at her with his small button-like black eyes, his wet nose covered by his two front legs, and his eyes looked innocent.
"Okay, okay, I won't chase you away." The girl chuckled, "It's not suitable for people to live here, let them live in the house across the street."
Uncle Huang tilted his head, not knowing whether he understood or not.

Bai Yang came out of the room yawning, and his mother took the opportunity to go into the room and mop the floor.
She could only go in after Bai Yang came out, to avoid seeing anything she shouldn't see.
Dad sat at the table and read the headlines. The TV was on. CCTV13 was broadcasting a live news show. The anchor's voice was always the background music in the room:
"It is believed that my country will officially launch the Sound Search Program next year. This is my country's first active exploration activity to search for habitable planets and even alien civilizations outside the Earth. The Sound Search Program may inject new vitality into the exploration of exoplanets..."
Bai Yang sat down on a chair, took a sip of water, pointed at the screen on TV and said, "It would be great if we had such a big antenna. Wouldn't it be awesome to use it for radio communication?"
Dad looked up and said, "That's FAST, the radio telescope."
"Can it fire, then?"
"It can only receive, not transmit." Dad said, "This big pot can hear aliens whispering. It's a waste of resources to use it for amateur radio. Did you stay up late last night to play with the radio again?"
Bai Yang turned his head to look at his mother and nodded quietly.
"What's going on?"
"There is one, the black station I mentioned to you last time. I contacted her again. Actually, it is not a black station." Bai Yang replied, "BG4MSR."
"BG4MSR?" Dad frowned.
"Her call sign."
Dad tried to recall, then shook his head, "I've never heard of this call sign. Could it be someone who has recently taken the certification exam... CRAC hasn't held any exams recently? Oh, I'm not sure. I've unloaded the idiot spectrum."
"I also removed the mental retardation spectrum."
"Why?"
"It won't open again." Bai Yang said, "Let's not talk about this. Dad, give me an idea. BG4MSR wants to meet me at the intersection of Alfalfa Garden Street and Zhongshanmen Road at 6 pm today. What should I do?"
Looking back now, Bai Yang didn't know why he agreed to her request so easily. He agreed so readily, but he tossed and turned all night long and couldn't sleep.
This is probably the dilemma of an innocent little boy, right?
Bai Yang thought so.
"Oh?" Dad was very calm, "She is also from Nanjing?"
Bai Yang nodded.
"That's great, you can go. Toads often have offline gatherings, you can exchange techniques." Dad was calm, "Do you know how your mother and I met?"
"How did you meet?" Bai Yang was stunned, thinking, could it be that fate brought us together through radio? Did they meet through the radio?
"I met her through a blind date."
poplar:……
"What I mean is that you don't have to be like me." Dad explained, "I was in the army back then. I had no conditions and no choice but to go on blind dates. If I hadn't been so desperate and had to go on blind dates, I would have been like this with your mom..."
"What's wrong with me?" My mother poked her head out of the bedroom, and the temperature in the room suddenly dropped by five degrees.
"...marry a perfect and excellent woman like your mother?" Dad said.
My mother snorted coldly and shrank back.
Both father and son breathed a sigh of relief.
"Yang!" Mom yelled from the bedroom, "I don't mind you meeting anyone. If you want to go, you can go, but you have to finish all the math papers handed out to me today! Teacher Liu emphasized in the group that there will be a review tomorrow!"
Bai Yang sighed. Before six o'clock this afternoon, he still had to overcome a mountain of books and a sea of questions that could crush a person.
Is there anything more difficult in the world than this?
