The little one's purse connects the two worlds, turning a desolate village into a paradise.

The video explains it in detail, but it doesn't show the installation process in real time; it only provides an explanation.

Fang Tiesheng read it over and over again.

The onlookers, listening to the repeated mention of the pulsed electric grid in the video, mostly looked at each other, completely confused.

"Mai Chong, what's a Mai Chong electric fence? Are you suggesting we smash it with wheat? That's such a waste of food."

"I just heard them say that if wild animals touch it, even domesticated livestock will get an electric shock and will avoid it. It sounds like the shock is quite strong."

"Continuous pounding of wheat, so you're going to keep pounding it with wheat?"

The village chief frowned. "You said it could be fatal? What exactly is this electricity?"

Apart from Ya Ya and Fang Tiesheng, the villagers of Lotus Village had never really figured out what electricity was. They only knew that it existed and that it had many uses, but they had never touched or used it.

It can only be understood literally as something that shines like lightning in the sky.

"Could it be that they're collecting the lightning from the sky and storing it inside that electric grid?"

"What is grounding? Ground is just the soil beneath our feet. What else can you put it in the sky?"

The murmurs of doubt grew louder and louder, but Fang Tiesheng was so engrossed in the feeling of knowledge flowing into his mind that he paid no attention to the outside noise.

As he listened, he quickly jotted down the key points with a pencil, feeling increasingly confident.

If this pulsed electric grid were deployed, even just a small section around the village, it would be enough to deal with anyone sneaking in with ill intentions.

If someone who doesn't understand this stuff touches it, they may suffer from paralysis and serious injury at best, or even die on the spot at worst!

After reviewing the information about the power grid, Fang Tiesheng pulled out the materials about solar water heaters written by Boss Zhao and secretly planned that this equipment should also be replaced. If it could be powered by the sun, he would pay extra to replace it with solar power, since they had no shortage of sunlight here.

Moreover, the prices are quite affordable; the most expensive part of the whole system is actually the most basic solar power generation system.

After clarifying everything, Fang Tiesheng immediately stood up and turned to Ya Ya: "Darling, shall we take out the solar panels and try them out now?"

"Should we bring them all out? There are so many big blackboards!" Ya Ya looked around the yard. "Brother Zhao said these boards are delicate and can't be bumped or knocked. Will it be bad to just leave them on the ground in the yard?"

Fang Tiesheng looked up at the sky, then at the villagers around him who were looking at him with curiosity.

He recalled the advice in the document that equipment installation should be prioritized on cloudy days or in the evening to avoid direct sunlight and thus significantly reduce the power generation of the photovoltaic panels.

It is also necessary to set up a support frame, fix it in place, and choose a suitable location with sufficient sunlight.

If it were a proper installation, it probably wouldn't work, but he should be able to try it out first without any problems, right?

"Let's put it in the backyard. The sun isn't as strong there yet. I'll just use a plank and try it out first."

"Should we put those two small white boxes in the backyard too? Or should I keep them for now?"

"Put it in the backyard too," Fang Tiesheng said after a moment's thought.

"it is good."

Ya Ya jumped off the chair and headed towards the backyard first. Fang Tiesheng immediately followed. Grandma Liu wanted to go with her, but Fang Tiesheng stopped her, saying, "Grandma Liu, I'll have Nannan help me put it down. Once she's done, she can come over. Don't worry."

……

"Put it here, Grandpa Fang." Ya Ya pointed to an open space under the eaves behind the house.

Fang Tiesheng nodded. "Okay, could you please take those two white boxes out and put them here as well? After you've put them away, go back to the front yard first. It's dangerous here, so Grandpa will figure things out on his own. I'll return your phone to you later."

The white box must be the lithium iron phosphate energy storage battery and inverter integrated machine that Boss Zhao mentioned.

"Okay." Ya Ya waved her little hand, and a dark board with small grids appeared out of thin air at Fang Tiesheng's feet. Because the board was very wide, half of it was in the shadow of the eaves and the other half was in the midday sun.

"Grandpa Fang, I've put the white box and this big bag of things here. This bag contains what Brother Zhao said we'd need for installation; it's called accessories, including tools and..."

Ya Ya couldn't remember, so she waved her hand randomly and pointed to the white snakeskin bag, "There are lots of things inside."

Fang Tiesheng leaned over and rummaged through the pile of cables, white squares (circuit breakers), and nails, which was heavy and full.

He'll just try it out; it should be enough.

He nodded immediately and thanked Ya Ya, "Okay, Grandpa understands. Thank you for your hard work, little girl. Go back to the front yard quickly, or Grandma will get worried."

"Okay! Grandpa Fang, please be careful. Call me if you need anything!"

After Ya Ya left, Fang Tiesheng looked at the things scattered on the ground. The big black board was exactly the same as the one in Ya Ya's picture book. In the book, this thing was placed on the roof.

It is said to be for better absorption of sunlight.

He crouched down and laboriously lifted the board, revealing two black threads underneath.

There's a story behind this loose thread. Fang Tiesheng put down the board and began to review the notebook and the video on his phone again.

The sunlight shone on the board, reflecting a pale white light. The naked eye could not see any movement, but changes had already quietly taken place inside the board.

The moment the sunlight sets, the light strikes the microparticles inside the silicon wafer. Driven by the light, these microparticles move around and slowly converge into an invisible current, which flows along the internal pathways of the board towards the bottom.

Fang Tiesheng put down the notebook in his hand, put his phone in his pocket, picked up the board again, stared at the wire ends on the left and right sides, his brows furrowed tightly. It said that the two wires were divided into positive and negative terminals, but which one was positive?

He shakily extended a finger and gently touched one of the threads. Finding nothing amiss, he grew bolder.

Use your knee to lift the board, and use your other hand to hold the end of the thread on the other side.

The moment I grabbed the thread with both hands, a tingling sensation suddenly shot up my arm.

The force wasn't fierce, nor was it the kind of excruciating pain. Rather, it was a fine and persistent tingling sensation that spread from his fingertips all the way through his body. Fang Tiesheng's mind went blank for a few seconds, his heart tightened suddenly, and he quickly flung his hands away, taking several steps back.

A tingling numbness lingered in my palms, and my arms were stiff for a while before they regained their flexibility.

He stared at the board on the ground, still shaken, his face filled with shock.

Is this the power of electricity?

In such a short time, less than fifteen minutes in the sun, it has such great power!

These points were indeed noted in the precautions given by Zhao Junchen, but the content was too much and too complicated, and Old Man Fang forgot them for a moment, nor did he understand the power of electricity.

Having learned their lesson, they dared not touch or tamper with anything, and when they looked at the board again, their eyes held a hint of fear.

As his brain, which had been numb from the electric shock, gradually returned to normal, Fang Tiesheng picked up his notebook and instruction manual again and began to read them word by word.

"Insulated gloves, and a mat underneath, so you can't touch the positive and negative at the same time..."

Old Fang muttered to himself as he began rummaging through the white snakeskin bag. He pulled out a pair of thick, turmeric-colored gloves and carefully put them on. Then he picked up a dry, thick wooden board to place under his feet before moving back to the solar panels.
