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

Fang Tiesheng and Granny Liu paced back and forth at the spot where Ya Ya had disappeared.

Although it wasn't the first time Nannan had come home late, and it was still broad daylight in that area with the all-powerful Duck Fairy watching over her, she was still so young, how could they truly put their minds at ease?

The village chief and Granny Li led Da Niu and Hu Zi up the mountain, but they haven't returned yet.

The village chief had told him that he had received the Duck Fairy's promise that the Duck Fairy would help them collect the treasure the next day.

However, there were still many corpses and bloodstains in that place. They weren't afraid, and the Duck Fairy certainly wouldn't mind either, but Nannan was still there, so they had to go there in advance to investigate and clean it up thoroughly.

The night was deep, and before we knew it, it was already 9 PM.

Finally, a small figure appeared in the small mud house, and the two people who had been hanging in suspense finally felt relieved and breathed a sigh of relief.

Ya Ya raised her hand to rub her sore eyes and yawned slightly: "Grandma, Grandpa Fang."

Grandma Liu quickly stepped forward and asked softly, "Nannan, why are you so late today? What happened?"

Ya Ya took off her big work clothes and little shoes, climbed onto the kang (a heated brick bed), and lay down on the quilt: "Auntie took me out. Grandpa Village Chief gave me a big gold bracelet, and Auntie said we had to go to a gold shop to sell it. The gold shop was on another street, and Auntie took me there in a two-wheeled yellow cart. That cart went really fast, almost like a bus."

Fang Tiesheng opened his notebook, and the pencil scratched on the paper.

"On the street where the gold shop is, next to it I saw a huge red-signed shop called Xinhua Bookstore. There were so many books inside... My auntie with the bracelet sold it for over 50,000 yuan at the gold shop... There was so much gold shining in the gold shop, and in a transparent box there was a really big, beautiful little yellow bird headdress."

Ya Ya mumbled incoherently, her voice growing softer and softer: "After my aunt and I finished selling the bracelets, the bookstore opened just then, so my aunt took me inside to buy books. I told my aunt I wanted to buy books for Grandpa Fang, and he couldn't understand those blackboards, so he scratched his head until his hair fell out."

Fang Tiesheng paused, his pencil tip snapping, his old face inexplicably turning a little red.

"Auntie picked out a lot of books for me, and several news articles, which are saved on my phone..." Ya Ya said, waving her little hand, and two plastic bags full of books and her phone appeared on the table in front of Fang Tiesheng.

"Oh right, when my aunt was saving the video for me, she said my phone was about to run out of battery, so I charged it for a while at the store. I also bought so many things... Aunt Chuntao's sauce..."

As she was talking, Ya Ya's head sank down, and she buried herself in the soft blankets and fell asleep.

Fang Tiesheng took a deep breath, finished writing the last few words, and quietly packed up the two bags that Ya Ya had made, putting his phone in his pocket. Then he whispered a greeting to Grandma Liu, who was wiping Ya Ya's face, and went out the door.

As soon as he stepped out of the small mud house, Fang Tiesheng quickened his pace.

He had just glanced at these books, and in one bag, almost every single one had the word "electricity" on it!

He didn't care that it was pitch black inside and outside the yard. He hugged the plastic bag tightly, and his two old legs were incredibly agile at the moment. He rushed towards Doctor Chen's house.

"Old Chen, Old Chen, this is good stuff!"

As soon as Fang Tiesheng entered the courtyard, he lowered his voice and began to shout.

The windows of Dr. Chen's house were also sealed tightly. At this moment, he was wearing his work clothes, with a solar-powered clip-on lamp attached to the table, sitting at a small wooden table in the main room, taking notes with a pencil in one hand and an exercise book in the other.

A large picture book was spread out in front of me, one of the two picture books that Ya Ya had brought back earlier—"The Human Body You Must Know".

The novel knowledge he had never heard of before, such as human cells, carbon, hydrogen, and oxygen, gradually entered his mind, as if pushing open a door that he had never dared to imagine before.

The pencil and notebook in his hand were specially given to him by Fang Tiesheng. Originally, the old man Fang only intended to give him one set, but when he saw that the old man had hidden quite a few, he shamelessly took a few more sets.

Now that I've used it for a while, it's become exceptionally easy to use.

This thing is amazing. If you make a mistake, you can use the soft, elastic eraser on the other end of the pen to erase it cleanly without wasting the paper. The pen strokes are small, so you can write twice as much content on a single page as usual.

Xiong Bo looked pale and clutched his stomach, running to the outhouse again and again.

Dr. Chen glanced at it but didn't bother to pay any attention.

As soon as he entered the house in the afternoon, he smelled the stinky tofu. He knew without a doubt that it must have been brought by Da Niu. And, this little bear brother even ate some.

I warned you beforehand that you shouldn't eat these kinds of oily and spicy foods. Humph, you couldn't control yourself, and now you've got diarrhea. You only have yourself to blame.

Xiong Bo had been struggling with his stomach for several times when he moved back to the room and sat on the edge of the kang (a heated brick bed). He was wide awake and felt an intense, agonizing itch in his heart.

Why are there so many strange and interesting things here?!

The object on Dr. Chen's desk, made of two small black boards joined together to resemble a clip, looked ordinary except for its peculiar material. How could it emit light out of thin air as soon as night fell, without any kerosene or flame inside?

There was also the pen Dr. Chen held in his hand at night, the paper with a peculiar texture, and the books with unusual writing—nothing was concealed in the slightest.

Why would an ordinary family openly display such a strange object to an outsider like him? Could it be a deliberate test?

Xiong Bo's mind was in turmoil; otherwise, he would have gouged out his own eyes to avoid seeing too many secrets.

But he couldn't bear to gouge out his eyes; this place was too strange, and many things seemed like little hooks, piquing his curiosity.

Just now, when he returned from the outhouse, he saw Doctor Chen holding a small device with a crank handle. He inserted a pen into it, then gently turned the handle, and fine wood shavings fell onto the table. The pen tip instantly became sharp again.

What kind of mechanism is hidden inside? How is the blade placed and secured in such a small machine? What kind of material is the outer casing made of, and how can its color be so bright?

Dr. Chen glanced at Xiong Bo, who was fidgeting and scratching his head, and a barely perceptible smile appeared on his lips. He didn't speak but continued writing diligently until he heard Fang Tiesheng's low call from the courtyard. He looked up and looked towards the door.

"What good stuff?"

"It's books! Books on electrical engineering, and books on medical and health care, lots of books!" Fang Tiesheng put the two plastic bags he was holding on the table.

"What?" Dr. Chen suddenly stood up, ripped open a plastic bag, and stared at the several brand-new books still wrapped in plastic. His hands trembled slightly.
