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

He opened the small black book whose cover read "Learn Electrical Engineering from Scratch," glanced at the table of contents, and saw that the first item was titled "Concepts of Electricity!" Below that were several sub-sections on current, voltage, and resistance.

Further down are circuit structure, related symbols, circuit connection methods, etc...

Fang Tiesheng also joined in, and the two of them held the book, their hands trembling like leaves.

With a thorough understanding of these books, there's definitely hope for improving the village's solar energy and power grid!

They were finally able to glimpse some of the principles behind electricity, such a magical and powerful energy source, instead of just guessing based on a few instruction manuals.

"Oh right, there are also operation videos, several of them!" Fang Tiesheng said, trembling as he pulled out his phone.

"Take a deep breath and sit down," Dr. Chen advised, though his own hands trembled slightly.

"Okay." Fang Tiesheng let out a long sigh and sat down. "Shall we watch the video that Nannan mentioned first?"

The old wooden door couldn't block out the sounds from the main room at all, and besides, he hadn't even closed the door. Xiong Bo simply lay down on the kang (a heated brick bed) and covered his head.

"Family members, today I'm going to share with you a wiring method for the inverter of our photovoltaic power station. How should a home-use pure off-grid power station be wired..." A female voice suddenly rang out from outside, making Xiong Bo's hair stand on end.

Were there any women outside? No, right? How come there's a woman's voice?!

He tentatively poked his head out from under the covers and peeked out.

There are no women!

Where did that sound come from? It was so clear!

"Should we keep the younger brother inside out?" Dr. Chen asked, scribbling a few words on a piece of paper as he watched the video.

"No need, keep hooking him up." Fang Tiesheng quickly wrote down a line as well.

The two old men exchanged a smile. "Brother Xiong is a coppersmith who is skilled in mechanical arts."

The coppersmith is proficient in smelting copper, forging components, mixing copper and tin, and various intricate mechanisms. He practices soldering and riveting daily, and his skills are solid and experienced. In particular, this person is the most respected head coppersmith, and his knowledge and skills are likely to be far greater than those of others.

If he could understand the principles of current circuits in the book and fill in some basic gaps in his knowledge, with his skills honed over many years, he would definitely be of great use in the construction of the village's photovoltaic lines and the subsequent hydropower projects!

It's better to pique people's curiosity and get them to participate willingly than to ask for their help, which is why they act this way.

When Fang Tiesheng and Dr. Chen finished watching the fourth video, the time on their phones was already 00:23. The video itself wasn't long, but the two of them would write down each sentence as they watched, frequently pausing and rewinding to analyze the video footage while combining it with their written notes. As a result, a video that was only about ten minutes long took them at least half an hour to watch.

Suddenly, a series of light footsteps came from outside the courtyard.

The village chief and Li Guixiang led Da Niu and Zhao Hu into the main room.

"Here, more new books?" The village chief saw several books spread out on the table as soon as he entered the room. They were brand new and white, with a faint smell of ink.

"Electricity? Is it about those things we've been dealing with lately? Have you gotten any clues from reading these books?" He leaned closer to the village chief and noticed what was written on the cover. He had been learning to read on the books for a few days, and while he didn't recognize the other characters, he remembered the character for "electricity" very well.

Fang Tiesheng nodded slightly: "I'm starting to get started. After reading this book for beginners and watching the videos, I should be able to assemble that solar power system."

"Good, good, good!" The village chief patted Fang Tiesheng on the shoulder with satisfaction. This set of things was so expensive, costing more than 10,000 yuan. It would be a waste to leave it there if he couldn't learn how to use it.

"How's it in the mountains?"

"We've patrolled the mountains once. The three young men did a great job; they didn't miss a single one. It's just that those horses get startled by any noise at night, so we didn't move."

The bodies were all buried in deep pits, thankfully most of them were inside the cave; only a few remained outside, otherwise it would have been much later to return. The remaining bloodstains and traces along the way were also cleaned up.

"That's good," Dr. Chen replied.

"Tomorrow we'll go up the mountain with Nannan, and we can bring those three horses back together. You didn't see it at noon, but the white horse became docile as soon as Nannan approached it, it was so strange!" Da Niu said excitedly, then glanced at Xiong Bo peeking out and chuckled again: "Brother Xiong, still awake?"

"Thanks to you, he had diarrhea all night," Dr. Chen said expressionlessly.

Da Niu: ...

"Alright, it's getting late, you should all get some rest. We have to go up the mountain tomorrow." The village chief waved his hand. "You two should also get some rest and not stay up too late reading."

The night passed in the blink of an eye.

Before dawn, there was already commotion coming from Granny Liu's courtyard.

Ji Chuntao was always the first to arrive each day. After washing up, she would get busy, her face illuminated by the flames in the stove, though she seemed somewhat distracted.

She had just glanced into the cellar and found no new ingredients, no chili peppers, and the meat and pickled cowpeas were still the same daily amount, not even a single yellow-skinned free-range chicken.

It seems her idea from yesterday didn't work; she didn't put the sauce jar back, but it must have been left at the shop.

I don't know if the sauce recipe I came up with will suit the tastes of the people in that area.

Just as they were feeling uneasy, the village chief led Xiaodouzi and Xiaoshuanzi into the yard. He had promised the three children yesterday that he would go to see the chicks hatch.

The yard gradually became lively. Ya Ya rubbed her sleepy eyes, still feeling a bit dazed. But when she remembered that Grandpa Village Chief had said they were going to see the chicks hatch today, she forced herself to get out of bed, pushing her sleepiness away.

"Darling, why don't you sleep a little longer? You came back so late yesterday." Grandma Liu patted the warm quilt.

"I'm not sleeping anymore, I'm going to watch over the eggs. Grandpa Village Chief said the chicks will hatch today, so we all have to get up early!"

Grandma Liu shook her head and got up, leading Ya Ya to the yard to wash up.

Little Bean and Little Shuanzi followed Ya Ya eagerly when she came out, like two little ornaments.

After a quick wash, Ya Ya turned around and saw Aunt Chun Tao standing to the side, her mouth moving as if she wanted to speak but was hesitant to do so.

"Aunt Chuntao, I have good news to tell you!" Ya Ya put her mouthwash cup and small towel aside and waved mysteriously to Ji Chuntao.

Ji Chuntao's eyes lit up—good news!

The village chief and a few others also gathered around.

"Last night I told Auntie and Grandma Wang about your idea, and Grandma Wang said it was great. She even said she would help us buy a boiler so that customers can cook their own noodles. She also thought of a price for us, twenty-five a bowl. I let Auntie and Grandma Wang try your sauce, and Grandma Wang really liked it, so I gave her a jar as a gift." Ya Ya rattled off a long string of words.

Ji Chuntao clenched her clothes. Grandma Wang was a good friend that Nannan often talked about. She was a big customer of the shop. If she liked the food, then she could rest assured.

"Later, Grandpa Zhang came over and tried Auntie's sauce. Then, Grandpa Zhang said he wanted to buy some for his employees as holiday benefits. Grandma Wang helped me set the price at forty-one jin (500g). Grandpa Zhang bought a hundred jin and even gave me all the money. Auntie went with me to buy two big buckets and a big pot, and..." Ya Ya scratched her head. What else was there?

"Oh, there's so much meat, chili peppers, and chicken! I've bought it all! Auntie, can you tell me how much we need to make 100 jin? I'll put away any leftovers." As she spoke, Ya Ya waved her little hand, and suddenly a huge iron pot, two shiny silver thermos flasks, piles of fresh meat, whole chickens that had been prepared, and a small mountain of tricolor chili peppers appeared in the yard.
