Zheng Xudong saw Lao Wen, who was doing chores, like this now, and sighed in his heart: "This may be the sadness of people living in our country!"

"Master Wen, I have a job as an electrician and I am looking for your help... Before Zheng Xudong finished speaking.

Master Wen still lowered his head and hurriedly waved his hands, "Boss, these are my jobs, what kind of work do you say." ”

It is not easy for people who have experienced that sport to make changes to them, Zheng Xudong can only say as pleasantly as possible: "Master Wen, where is the total power supply of our villa? ”

"Change the power supply?" Master Wen obviously didn't understand it all at once, but he quickly reacted, "This may not be something that one of his subordinates should know", turned sideways and pointed to a room at the back of the villa, "Boss, the main switch is in that small room, I'll take you over." ”

Zheng Xudong saw the room that Wen You pointed to, "In this way, Master Wen, you go over first, I'll go back to the room and get the new power supply, and then I'll arrive, by the way, you have to pull the brake to change the power supply, see if anyone is using electricity, notify me, don't hurt anyone." Seeing Master Wen's unresponsive face, he sighed in his heart, turned his head to Tang Luoyong and said, "Brother Tang, go and take a look, and tell everyone that there may be a power outage for five minutes." If you have work at hand, deal with it quickly, and don't hurt people due to power outages. ”

"Okay, boss, I'll take a walk around the villa!" After speaking, Tang Luoyong ran to the workers' room and the monitoring room.

"I didn't expect the boss to be young and still know how to use electricity. Master Wen whispered.

"Hehe! I learned it at school. Master Wen, I'm going to get a new power supply, and let's gather in that small room in a while, okay?"

"Okay, boss, I'm going back to get some electrician's tools too. After speaking, Wen You bowed and turned to leave.

Zheng Xudong walked quickly to the room, came to the room on the third floor where the miscellaneous items were placed, and took out a large battery that Vivian gave to him before leaving, this battery is smaller than the car battery, and it is made of black opaque glass.

At that time, Vivien gave him a total of 100 batteries, telling him that each of these batteries was 200,000 kilowatt-hours (200,000 kilowatt-hours of electricity). At that time, I didn't look carefully because I was in a hurry to leave by plane, so I took it out here and took a closer look, and there was a device similar to an air switch embedded on the front of the battery, with a socket for the access cable on it, "It seems that Vivian knows that the interface of this large battery is not available for ordinary sockets, so she installed the kind of cable access standard socket when entering the house from the Electric Power Bureau." "And there is also a brake handle on the air switch, which can be pulled down during installation and pushed up after installation. When he turned this big battery to the other side, he still saw the standard socket interface for home three and two items. "It seems that Vivian has thought quite thoughtfully, so that she can easily work with this large battery when she goes outdoors. It's just that the volume of the battery is slightly larger, of course, this is also the decision to be so large after research at that time, and the smaller version is reserved for future upgrades. ”

With the battery, which weighed five kilograms, he walked out of the room and walked towards the room with the main power supply.

It seems that this battery has room to reduce its volume in addition to reducing its mass, and this five-kilogram weight is generally not enough for a small girl to hold. In fact, 99% of the weight is tempered glass.

When he came to the room, Wen You and Tang Luoyong were already waiting there, Tang Luoyong was very discerning, and saw Zheng Xudong holding a black thing like a car battery, so he hurriedly changed three steps to two steps and came to him to pick up the "battery".

Zheng Xudong saw that Master Wen was wearing an old-fashioned brown wide plate belt under his crotch, and there was a cowhide plug board for electricians on the butt behind the belt, and an old-fashioned electrician's knife, an electric pen, and two screwdrivers, one with a flat head and the other with a cross plum head. Two screwdrivers are plugged into a jack. As soon as you see this set of equipment, you know that this is a professional electrician. Zheng Xudong's father told him that professional electricians in the eighties and nineties were very popular, belonging to technicians (skilled workers), and had professional titles, especially high-voltage and strong electrical electricians. At this time, Master Wen's buttocks happened to be equipped with "three pieces of iron", an electrician's knife, an electric pen, and a screwdriver. Zheng Xudong's father told him that who wanted to change a fuse, a switch, a socket, a light bulb, a light tube, a ballast, a bubble... If you want to find an electrician to come to the door, if you are an electrician in the unit, you will have to prepare wine and food at home if you don't give money, this is the meaning of that sentence, "Three pieces of iron on the buttocks, everywhere you go, you are a guest (qie three sounds)!"

"Master Wen, you have three pieces of iron on your buttocks, you must have been a guest everywhere you went back then!" Zheng Xudong said jokingly.

Master Wen was studying the "battery" that he received from Tang Luoyong's hand, and he was obviously a little surprised when he heard Zheng Xudong's words, and raised his head to look at Zheng Xudong for the first time, and whispered: "I didn't expect that the little boss still knows such an old sentence, this sentence is not magical, this sentence is popular in the Northeast, and your parents are from the Northeast?"

"My dad is from Jilin Province in Northeast China. Zheng Xudong replied.

"That's right! When I was young, I worked in the border area of Hei Province, so I have heard this sentence for so many years... Somewhat excited. Speaking of this, Master Wen's eyes were foggy. After speaking, he didn't continue the topic, his eyes obviously flashed with a light that he didn't have just now, and said: "Boss, this is a big battery, right?" Seeing Zheng Xudong nodding and continuing: "Then it is definitely not the popular lithium battery inside, let alone lead-acid, then it is inside... Seeing that Zheng Xudong didn't answer his question, the light in his eyes dimmed, lowered his head and stopped talking, put the battery on a table on the side, then opened the power box, pulled down the air switch from the electric switch in the electricity bureau into the house, and with a "bang", the electricity was cut off first. Then take out the screwdriver from the back of the buttocks, loosen the screws of the red, green, and black power cords of the air switch into the home, and then take off the cables in turn. Next, he removed the large air switch from the original power box and set it aside.

"Don Jr., you help me with a hand. Saying that, Master Wen asked Tang Luoyong on the side to help hold the battery and connect the three-color cable to the big black "battery" in turn. Fix the cable tightly with a screwdriver, and then re-insert the large "battery" into the power box. After carefully checking again, there was no problem, Master Wen put his hand on the switch of the big "battery", looked back at Zheng Xudong, saw Zheng Xudong nodded, and he closed the power handle of the air switch with his hand steadily. "Pop" is not loud, and then I saw ten LED lights the size of mung beans appear in the upper right corner of the big "battery", each light is green, except for the first green light flashing, the other nine lights are stable on.

"It seems that these ten lights represent the internal power balance of this large battery. Master Wen whispered.

"Boss, how many words are stored in this battery?" asked Tang Luoyong, who was standing next to Zheng Xudong.

"Two hundred thousand kilowatt hours. ”

"Two hundred thousand... What?" Tang Luoyong thought he hadn't heard.

"200,000 kilowatt-hours of electricity is 200,000 words. Master Wen said on the side. After saying that, he said to himself: "It's amazing! Even the current graphene technology can't reach this indicator." IT'S NOT NUCLEAR FISSION OR NUCLEAR FUSION, OH MY GOD!AMAZING!"

"me, old Wentou, did you speak English just now?!I didn't know you could speak English for so long, it sounds very London!" Tang Luoyong next to him said in surprise.

Hearing Tang Luoyong's words, Wen You's face turned red all of a sudden, and he didn't speak for a long time.

"Brother Tang, you take Teacher Wen to get a better pair of short-sighted mirrors, and then buy a decent set of clothes. Zheng Xudong said.

"Teacher, Wen You, Old Man Wen!?" Tang Luoyong's mouth was stuffed into his fist.

"Boss, no, really no, I've been with this mirror for many years, and I already have feelings, so it's not troublesome. "Master Wen", who had changed the power supply, said nervously.

"Go, Brother Tang, follow Master Wen to finish things and come back. After speaking, Zheng Xudong walked out of the equipment room of this villa.

I happened to meet Liu Yifei who came here to find him outside, "I heard that you are changing the power supply, is it that new scientific and technological achievement?" Seeing Zheng Xudong smiling and nodding, Liu Yifei stepped forward and grabbed Zheng Xudong's hand and said, "It's been successful, the product is out, take me to see it." ”

Zheng Xudong also wanted to show off a little, so he took Liu Yifei's hand and came to the equipment room again, at this time Tang Luoyong was pulling the "old Wen head" in his mouth and walking out, it seems that Wen You still has a feeling of "Xiucai meets soldiers, and he can't explain it clearly", and when he saw Zheng Xudong, he only said "thank you!" and was dragged away.

Zheng Xudong opened the box of the power supply, revealing a black opaque battery that was continuously powered.

Liu Yifei stepped forward and took a closer look and asked, "How many kilowatt-hours of electricity is stored in this?"

"Two hundred thousand kilowatt-hours of electricity. ”

"OH MY GOD!" LIU YIFEI SAID WITH HIS LITTLE HAND OVER HIS MOUTH, "OUR VILLA OF OUR SIZE CONSUMES 1,500 KILOWATT HOURS OF ELECTRICITY EVERY MONTH, BUT I ESTIMATE THAT IT IS NOW IN SUMMER, AND AIR CONDITIONING IS USED MORE, SO IT CONSUMES MORE ELECTRICITY, AND IT WILL CONSUME LESS ELECTRICITY IN WINTER AND SPRING." On average, every month... It's about 1,200 to 1,300 degrees. By the way, young master, do you know how much the electricity price in the magic city is now?"

"Do you need so much electricity every month?" Zheng Xudong was the first time someone told him about the electricity consumption of the Yan family's garden villa.

"Of course, indoor lighting, air conditioning, household appliances, as well as workers' daily electricity, security personnel monitoring facilities work 24 hours a day, 365 days a year, night ring lights, lawn lights, rockeries, gazebo lights, fountains... ”

"Stop, Yifei, in this way, we can save this bit of electricity. ”

"Of course, this is still when I told them that there are usually some landscapes, like rockeries, and the lights of the gazebo are turned off if they are not in use, let alone the fountain. It's really expensive to live in such a big mansion. ”

"My dear, now it's okay, there are 200,000 words of electricity in this battery, just according to these landscapes, all the fountains are used, and 2,000 kilowatt-hours of electricity per month is enough!" Liu Yifei nodded, "Then you said that this villa is running at full capacity, how long can this battery last?"
