Double-Cut During the War of Resistance: My Wife Came from 1937

The two shopped in the supermarket for a long time, and before they knew it, it was closing time.

"They're about to close for the day, let's hurry and pay the bill!"

Instead of going to the cashier, Ma Hongwei led Xia Weiwei to the self-checkout machine.

"Now, besides the cash register, some people also prefer self-checkout!"

Ma Hongwei demonstrated: "These items all have barcodes on them; you can just scan them."

After everything was swept, Ma Hongwei said with a smile, "Let me show you a magic trick!"

He clicked on the facial recognition payment option, and after his face was identified, the payment was successfully deducted.

"In modern society, our fingerprints and facial features can be linked to our accounts!"

Ma Hongwei said, "Even if you don't have a phone or money with you, you can pay by scanning your face or fingerprint."

"Amazing, absolutely amazing!"

Xia Weiwei sighed sincerely.

The two men, carrying their belongings, crossed the road and the square, heading towards the bread cart.

It's already past nine o'clock at night, but the outside is still brightly lit.

However, there were far fewer people in the square.

On the way back, looking at the dazzling lights, Xia Weiwei couldn't help but ask, "Hongwei, don't you turn off the lights here at night?"

Ma Hongwei said, "After the designated time, all the lights in the buildings will be turned off, but the streetlights on the main roads will stay on all night because many people drive at night."

"How much electricity is being wasted!"

Xia Weiwei immediately felt a pang of sympathy.

In 37, electricity was an absolute luxury, accessible only to government departments, factories, and the wealthy in the city.

In many places, streetlights still use kerosene lamps.

In this future world, streetlights are not only many times brighter, but they also stay on all night long.

"Now that there's plenty of renewable energy, we're not worried about wasting it at all!"

Ma Hongwei said, "In addition to thermal power generation, we also have hydropower, wind power, solar power and nuclear power. These renewable energy sources account for 38% of the total power generation."

"A hydroelectric power station can generate electricity as long as the water keeps flowing; a wind power station can generate electricity as long as the fans are erected and the wind keeps blowing; a solar power station can generate electricity as long as semiconductor materials are placed there and sunlight shines on them!"

"What did you say?"

Xia Weiwei exclaimed, "You're saying that wind and the sun can both be used to generate electricity?"

Xia Weiwei was aware of hydropower generation.

In 1912, many patriots built the Shilongba Hydropower Station, which was the first hydropower station in China, although its power generation capacity was only 480 kilowatts.

Subsequently, many places began to build small hydroelectric power stations.

However, Xia Weiwei had never heard of wind power or solar power.

Wind and the sun are both invisible forms of energy; how can they be converted into electricity?

This is truly too surreal.

"Yes, both wind and solar power can generate electricity."

Ma Hongwei said, "When we get back, I'll show you the video, and you'll understand immediately. All of this is available online."

"network?"

Xia Weiwei heard that name again.

She had heard this term before when she was ordering and paying by scanning a QR code.

Once you leave the main roads of the county town, the streetlights suddenly disappear, and the surroundings become pitch black, with only a few scattered lights visible.

When we returned to the village, we saw the bright streetlights again.

However, the village streetlights are far less bright than those on the main roads.

Xia Weiwei asked, "Are the streetlights in the village also on all night?"

"I remember when I was a child, the streetlights in the village would go out at 8:30 p.m.

Ma Hongwei replied, "Later it was changed to solar energy, which absorbs sunlight during the day and can keep the lights on all night."

He got out of the car, opened the garage door, and drove the car inside.

After locking the door, Ma Hongwei took the things down and said to Xia Weiwei, "Let's go inside!"

"OK!"

Xia Weiwei nodded and quickly followed.

Upon entering the main room, Ma Hongwei turned on the living room light and placed the items on the table.

He said to Xia Weiwei, "There's running water here, you can wash your hands!"

As he spoke, Ma Hongwei went to the bathroom, turned on the water heater, and then began to wash his hands.

Their restrooms only have facilities for washing and showering; the toilets are located in the yard.

Xia Weiwei took a newly bought towel and went to the bathroom.

Ma Hongwei took some fruit to the kitchen to wash it and put it in a small iron basin.

When I arrived in the living room, Xia Weiwei had already washed her hands and was sitting on the sofa.

Ma Hongwei placed the iron basin on the coffee table and said with a smile, "Come on, try some fruit from the future!"

"Thank you for your hospitality!"

Xia Weiwei picked up a strawberry and took a small bite.

"These strawberries are so big, and they're so sweet and sour, they're delicious!"

She had eaten strawberries before, but those were small wild strawberries, and neither their taste nor their sweetness could compare to this.

Xia Weiwei picked a red grape, put it in her mouth, and her eyes widened again.

"These grapes aren't sour at all, and they're seedless!"

Ma Hongwei said with a smile, "Our fruits have been improved over many generations. People like sweet fruits, so we keep increasing the sweetness. It's hard to spit out the seeds, so we simply remove them directly. That's the power of technology."

After the two ate some fruit, Ma Hongwei took out another SIM card from his phone and inserted it into the new phone.

He always had two SIM cards in his phone, so he could temporarily give one to the other person to use.

Unfortunately, all credit cards now require real-name registration; you can't just apply for a card as easily as you used to.

Ma Hongwei connected his new phone to Wi-Fi and logged into WeChat using another SIM card.

Ma Hongwei handed the new phone to Xia Weiwei, smiling as he said, "Take this phone; now it's time to witness a miracle!"

"Um?"

Xia Weiwei was very curious about what other miracles this phone could perform.

"Ta-da~ Ta-da~"

After Ma Hongwei pressed the video call button, both of their phones rang simultaneously.

Xia Weiwei wasn't particularly panicked; she just assumed it was a function similar to a telephone.

Ma Hongwei demonstrated: "To connect the video call, press this green button!"

As soon as the call connected, Xia Weiwei saw Ma Hongwei on her phone.

"Hi, Vivi, good evening!"

Ma Hongwei stood up, greeted everyone, and walked towards the bedroom.

"We can actually see each other directly?"

Xia Weiwei's beautiful eyes widened, and her red lips parted into an "O" shape.

Despite having witnessed many incredible things today, she was still shocked by the video call.

"Yes!"

Ma Hongwei sat on the bed in the bedroom and said to Xia Weiwei, "In our era, even if two people are thousands of miles apart, one in China and the other in the United States, they can see each other instantly through video calls."

"This is absolutely incredible!"

Xia Weiwei said, her face full of shock.

In another era, telephone calls could only be made locally. To make calls across cities, one had to go to a special place, not from their own home.

Due to the high cost, most people chose to send telegrams instead.

However, in later generations, even an ordinary person could communicate "face to face".

This is no different from face-to-face communication.
