My house's electrical wiring dates back to the Tang Dynasty.

Those missed calls were probably reminders to pay the electricity bill.

After clicking "Pay Now" and thinking about it, I paid 20 yuan.

20 should last a long time, right?

There weren't many electrical appliances in those places, just refrigerators, fans, and lighting.

If each household uses an average of 200 kilowatt-hours per month, then five households would use 1000 kilowatt-hours. If the usage exceeds 400 kilowatt-hours, and each kilowatt-hour costs 0.89 yuan, then the total cost would be 1123 yuan, which would take 12 years.

That's enough for now.

It hasn't recovered yet, probably because I didn't go to work tonight.

I called the 24-hour hotline.

"I've already paid the electricity bill, why hasn't the power been restored yet?"

"It's nighttime now, and some systems may be in maintenance mode, so processing will be delayed until the next day." Upon hearing this, the other party asked for Li Mingbo's personal information and then said, "Mr. Li, your problem is abnormal electricity usage. For the past few months, your monthly electricity consumption has remained around 1,000 kilowatt-hours. Ordinary residents don't use that much electricity, and you don't answer our calls."

"I'm at a construction site in the wilderness, and there's no signal."

"Regarding your issue, we need to send someone to inspect it. When would you be available?"

"No need, I'll just pay, okay? Look at my personal account, I've already paid 20, isn't that honest enough?"

"This still won't work. With such a large electricity consumption, we suspect that you're manufacturing in a factory. Commercial electricity and residential electricity are different."

"That's right. We do some high-yield farming at home, growing mushrooms. The greenhouse is kept at a constant temperature 24 hours a day, so it uses a lot of electricity."

"Oh, I see. We'll send someone over to inspect tomorrow. Is that convenient for you?"

"I'm currently out and not at home. I won't be back for a few days. I'll contact you again when I get back."

"Okay, call us when you're coming home."

Li Mingbo hung up the phone.

No matter how much electricity you use, it's impossible for a single household to use over a thousand kilowatt-hours per month.

What should I do?

How to avoid the power company's on-site inspection?

"Hello, Mr. Chen, it's me." Li Shimin dialed the Chinese driver who often hauled his goods.

"Hello Mr. Li, how can I help you?"

"Yes, that's right. I'm growing mushrooms and I'd like to build a mushroom greenhouse. I was wondering if you knew how?"

"I'm sorry, I don't know how, but I can help you make the contact."

"Okay, I'll entrust this project to you, but I need it done quickly, within the next two days. We can discuss the cost; I need the money urgently," Li Mingbo reminded the other party.

"Okay, I'll get back to you in half an hour."

"Okay, I'll wait for you."

I just had a sudden inspiration and said that I grow mushrooms and have a greenhouse to keep them warm.

To pass the inspection, we had no choice but to set it up.

Twenty minutes later, Mr. Chen called to say that he had contacted a heating equipment supplier and would come over the next morning to take a look and do a detailed design.

I promised to come over this morning.

At nine o'clock in the morning, Chen drove to the scene with two middle-aged men.

"I want to build a greenhouse for growing enoki mushrooms here. It will consume about 1000 kilowatt-hours of electricity per month. It can be a bit bigger if needed. As the manufacturer, you know the professional stuff," Li Mingbo said.

Upon hearing Li Mingbo's words, the two exchanged a glance.

This is the first time I've heard such a strange request.

Instead of specifying the area size, they requested the amount of electricity required.

However, the customer is king, and they only need to provide the construction services.

"For enoki mushrooms, the fruiting period requires a temperature of about 12-15℃. If the outside temperature is very high, the cooling system will consume a lot of electricity. Considering the energy efficiency of air conditioners, heating systems, fan coil units, etc., it depends on the size of your building."

"How big can you build in two days?"

After observation by the manufacturer, a simple 40-square-meter plastic greenhouse was built.

However, the requirements are urgent, and the labor costs are high.

Including labor costs and equipment and material costs, the total is 25,000 yuan.

Li Mingbo wired the money directly and also gave Master Chen two thousand yuan as a reward for his hard work.

Once the payment was received, the manufacturer immediately called to have someone bring in the materials and begin construction.

Working overtime, the project was finally completed on the afternoon of October 12th, and the power was connected without any problems.

When everyone left, they also helped Li Mingbo clean up his house and take away the trash.

After everyone left, Li Mingbo called the power company.

That afternoon, people from the power company came to inspect.

I saw the greenhouse, which matches the registration information.

Li Mingbo's electricity usage was changed from residential to agricultural production and operation, and he was charged at the agricultural production electricity price of 0.6 yuan/kWh.

Li Mingbo didn't care whether it was a lot of money or a little, as long as he wasn't discovered.

Afterwards, Li Mingbo slipped a thousand yuan to the two inspectors.

The two accepted the gift, nodded, and promised to tell their employers when they got back. They also wished Li Mingbo a prosperous business.

We need to think of a way.

After the power company personnel left, Li Mingbo began to think about this problem.

It was impossible to get Li Shimin to save electricity.

The refrigerator and fan should always be on, and there should also be lights for illumination.

Li Shimin was nearsighted and couldn't function without the lights on.

Looks like I'll have to buy some solar panels to take with me.

This is a good idea.

Solar energy is more convenient, and a solar water heater can be installed at the same time.

I asked Doubao, and her suggestions included installing solar panels and a human-powered generator.

The human-powered generator was more reliable, as the Tang Dynasty had no shortage of people, but it could only be used as a backup.

I consulted with Doubao several times and obtained a list of equipment to purchase.

I. It has a power generation core:

单晶硅光伏板（500W-2000W）、磷酸铁锂电池组（24V 200Ah）+ BMS、MPPT太阳能控制器（12V/24V）。

II. Electrical energy output.

Pure sine wave inverter (500W-1000W), USB/DC interface.

III. Installation assistance.

Aluminum alloy photovoltaic bracket (foldable), photovoltaic cable, MC4 connector, insulating tape.

IV. Low-power devices.

Water heaters, radiators, etc.

V. Tools and Spare Parts

Screwdriver, wrench, spare fuse, MC4 connector.

Save the screenshot, check online later, and buy from reputable manufacturers for guaranteed quality.

Then, Li Mingbo made a WeChat video call to his wife, Lin Chunli.

"Baby, I'm home."

Lin Chunli was at home, cooking, wearing a scarf.

"Senior brother, you're back?" Lin Chunli smiled when she saw Li Mingbo, her eyes full of love.

"Yes, I just got back. I'm going up now, and it'll be home in about an hour and a half."

"Okay, I'll wait for you at the gate of the residential area."

"Okay, see you in a bit."

After hanging up the phone, Li Mingbo began packing his things.

First, the spearhead and the shaft.

The lance handle is quite long, about three meters, but fortunately it just fits in the off-road vehicle.

Five pieces of raw jadeite, five boxes of century-old wild ginseng, and five pieces of chicken blood stone.

Around 8 p.m., when they arrived in the county town, at the entrance of the residential area, they saw Chunli waiting there all alone in the twilight.

A sense of guilt welled up inside me.

"Didn't I tell you to wait for me at home? There's no need to get out," Li Mingbo said to his wife as he parked the car.

"I just came out for a walk." Lin Chunli smiled, opened the passenger door, got into the car, and put on her seatbelt.

After arriving downstairs, Li Mingbo took out the items and had Chunli watch over them. He then drove to the parking lot downstairs and took the items home.
