Qiao An'an tested it with a test pen, and it worked.
She was very satisfied with the result.
The power grid consumes a lot of electricity, and she didn't plan to keep it powered on all the time. She only planned to keep it powered on when she went to sleep at night to prevent anyone from climbing over the wall and entering her yard while she was asleep.
During the day, the power switch is right at hand, so if she discovers someone trying to do something to her yard, she can pull the switch at any time.
As long as it's not running 24 hours a day, the solar generator she installed can completely cover the electricity consumption of the energy-saving refrigerator and the power grid.
...
Whenever she has free time, Qiao An'an uses Ya Ya's toy binoculars to observe the neighborhood across the street.
In the past few days, several households in the same building as Ma Xiaotiao's have been completely ransacked by Ma Teng.
After looting the entire building, Ma Teng didn't go out to rob residents in other buildings. Instead, he moved his whole family to the top floor.
When Ma Teng moved into the top floor, he glanced in the direction of Qiao An'an's house.
The field of vision is limited, and Qiao An'an did not believe that Ma Teng could see what was happening in her small courtyard with the naked eye.
However, the greed of the human heart is limitless.
Qiao An'an guessed that Ma Teng didn't leave the building entrance not because he had a change of heart, but because he was afraid that he would be attacked by zombies in the community if he left. He was definitely not the kind of person who would sit and wait to die. After he and his family finished eating the things they had stolen in this building entrance, he would definitely risk going to steal from other buildings.
They even tried to take over her small courtyard.
Sure enough, less than a week later, Ma Teng smashed open the balcony glass of a neighboring apartment in the top floor of the building where he was currently living, and climbed inside. The male homeowner tried to resist, but Ma Teng smashed his head with a stick. The other family members hid in the bathroom in fear, but Ma Teng still dragged them out and threw them off the building.
There weren't many residents in the building to begin with, and they were all so frightened by Ma Teng that they hid at home and dared not come out. But hiding didn't solve the problem at all. Ma Teng went to each of the residents' doors one by one, according to the order in which he had spoken in the owners' group.
Qiao An'an was very glad that she had prepared the electric grid in advance.
Because she knew that once Ma Teng had taken all the buildings, it would be her turn across the street.
However, she wasn't entirely unprepared. The zombies on the road and the electric fence on the wall would at least prevent Ma Teng from easily conquering her small courtyard.
But the electric grid alone wasn't enough, so Qiao An'an dug out the women's fighting techniques she had previously used to defend against Song Chi's family. She practiced fighting every day by following the videos, and over time, even Ya Ya could throw punches along with them.
