I trade in both worlds

Xu Jin waited for a long time before he saw Xu Xu appear. He finally felt relieved and could observe the yard with peace of mind. Whenever he saw something he had never seen before, he would curiously go up to touch and look at it. Whenever he saw Xu Xu take a few steps, he would look back at her. Xu Xu simply followed him and watched him wander around the yard curiously.

Seeing the window of the main house, Xu Jin ran to the window, stood on tiptoe and touched the edge of the window, then ran back to Xu Xu, pointed at the large glass in the main house and asked, "Sister, what is that?"

Looking at the bright window, my restless heart began to become active again: "This is a glass window."

Glass was a luxury in the Dayun Dynasty. Ordinary people had never seen it, let alone used it. It was unaffordable for ordinary people. There were no more than three families in the entire Guoyin County that could install glass windows, and not all windows in the house could be installed with them. Only two panes of glass could be installed in the owner's room.

"Glass windows? We don't seem to have any at home," Xu Jin asked curiously.

"No." Xu Xu shook his head: "Glass is very expensive. It's not something that ordinary people can afford. Our family can't even afford it."

She had seen it a few years ago when she followed Yang Erzhu to visit someone else's house. It was the first time she saw such a bright house, and Xu Xu also asked Yang Erzhu if his home could be installed. Until she found out that this thing was not only expensive but also rare, and that she couldn't buy it even if she had money or connections, she knew that she would never be able to use it in her life.

This time, her adventure brought her to this magical place, where she saw that every household had glass installed on their windows. It shouldn't be too expensive, as it's something that everyone can use. Maybe she could buy glass from here and install it. But she didn't know how to buy it here. Forget it, she'd better understand the situation here first.

Xu Jin showed regret, holding Xu Xu's hand and said, "I will study hard in the future, and make money to buy glass for my sister to install in the windows when I grow up."

The childish and bold words pleased Xu Xu. She squatted down, hugged Xu Jin, and encouraged him, "Then you must work hard. Sister is waiting for you to install glass windows for me."

Thinking that his sister also needed him, he raised his eyebrows happily, his mouth corners turned up, his face was full of joy and satisfaction, he waved his little hands vigorously and said: "Wait, I will install such a window for my sister, it will look beautiful."

Rubbing his head vigorously, Xu Xu asked with a smile: "Do you want to see what's inside?"

"I want to." Xu Jin nodded fiercely, stretched out his hands and said, "Sister, hold me and see. I'm not tall enough to see inside."

He picked up Xu Jin and brought him to the window of the main house. The transparent glass reflected two dark figures. Xu Jin wanted to see more clearly, so he pressed his entire face against the glass.

The human figure disappeared, but looking through the window, there were things he had never seen before. Xu Jin pressed the button of a hundred thousand whys, constantly asking what this was, what that was, and what it was used for.

With a helpless look on his face, Xu Xu could only keep saying, "I don't know either. I haven't seen it either." In order to avoid being bombarded with questions, Xu Xu took him directly to the second floor.

Standing behind the stairs and looking down, Xu Jin exclaimed: "Wow, it's so high, I've become taller, I can see very far from here."

Xu Xu didn't care about him, as long as he didn't come to ask why. He turned his head to look at the big tree across the street, and saw the group of aunts sitting there chattering.

Xu Xu looked up at the sky, wondering if he could see the flying lump of iron again today. He hoped that he could let Xu Jin see it someday and broaden his horizons.

Today was destined to disappoint Xu Xu. She didn't know that the helicopter only came here occasionally and had no plans to fly here today.

Xu Jin began to feel around and look around. He squatted under the railing and saw a car on the road. He was so surprised that his mouth opened wide and couldn't close it for a long time. After the car passed by, he ran over and asked Xu Xu: "Sister, what is that thing that can move? Can I sit in it?"

Hearing the headache question again, Xu Xu looked depressed: "I haven't seen it either, so I don't know."

Xu Jin was not disappointed when he didn't get the answer he wanted. He pointed outside and continued to ask, "Can I go there to play?"

Afraid that he would sneak out to play, Xu Xu put the idea to bed: "No, we don't have the key here. What if we go out and can't come back? Then we can't go home. Xiao Zhun, Weiwei and Tiantian are waiting for us at home."

Hearing that he might not be able to go home, Xu Jin looked at the people coming and going on the street outside with a disappointed look on his face: "Okay, then we'll just wait and see here."

The child had a short memory and soon forgot about his loss. He began to touch everything on the second-floor terrace. When he turned on the switch on a basin, he was startled by the gushing water and screamed, "Sister, sister, look!"

Xu Xu looked at the water that kept gushing out, walked over and scooped up a handful of water with his hands. Looking at the clear water without any impurities, he was sure that it was clean, and turned to ask Xu Jin: "Where does this water come from?"

Seeing Xu Xu holding the water, Xu Jin also started playing with the water. He pointed at the silver thing on the wall and said, "Just push this thing and water will come out. Sister, what is this? Why is water coming out?"

Xu Xu, who was about to collapse after being asked, simply ignored him, reached out and pushed the thing, but found that he couldn't move it. He tried pushing it in the opposite direction, and the water column that had just poured down stopped immediately. It was amazing.

It would be so convenient if we had this thing at home. We wouldn't have to go to the well to fetch water, saving time and effort. Xu Xu couldn't help but open and close it, opening and closing it again, playing happily like a child with a new toy.

Xu Jin also wanted to play, but when he saw Xu Xu holding the switch, he remembered that he had seen a similar thing in the yard before, so he turned around and ran downstairs.

Xu Xu hurriedly shouted: "Where are you going?"

"I want to play this too. Let my sister play with the top one, and I'll play with the bottom one." Xu Jin said as he ran.

Looking at the switch in her hand, Xu Xu showed an awkward smile, turned off the water, got up and walked downstairs. It was getting late now, and she had to go back to check, lest the children wake up and can't find her and get scared.

Xu Xu stood at the door of the utility room and watched Xu Jin turn on and off the switch a few times before playing with the water. He quickly stopped him, "Xiao Jin, don't play with the water. We have to go back. Our brother and nephews will be scared when they wake up and can't see us. Come back next time."

Xu Jin turned off the water reluctantly, and walked to the utility room, looking back every three steps. Xu Xu took his hand and went back.

The time to return was just right. As soon as he came back, he heard Aunt Xu knocking on the door. Xu Xu asked Xu Jin to go and see if the children were awake.
