When Xiao Shanhai returned with his two sons carrying firewood, he saw a crowd gathered in front of his house from afar, and quickened his pace.

"What happened? Why are you all crowding around my house?"

Squeezing through the crowd, I discovered that his elderly wife was swinging a strip of cloth tied to a tree branch. Each swing produced a large amount of transparent material, which looked quite beautiful in the sunlight.

"Honey, what are you doing?"

Mu Lianrong stopped what she was doing and looked at Xiao Shanhai. Her smile froze. She glanced at the people around her and handed the branch in her hand to her grandson.

When did so many people gather? How come she didn't notice?

"It's nothing. Yunyun made this bubble solution for the kids to play with, so I'll try it out first."

Xiao Chunlei dipped a strip of cloth in bubble solution and said, "Grandma has been trying it for ages. If you don't come back soon, Grandpa, Grandma will have used up this whole basin of bubble solution."

Mu Lianrong glared at her eldest grandson: "Isn't this for you? Do you want to play with it or not? If not, your younger brother can play with it."

Xiao Chunlei stuck out his tongue: "My younger brother is playing with the smaller one. I'll let him have it in a bit."

Mu Lianrong walked over to Xiao Yunying and stood next to her, watching the children play with the bubble solution. She asked, "Girl, how do you make this bubble solution?"

Xiao Yunying said, "It's the potion I bought from that overseas merchant before. A few drops can be mixed into a large basin. I thought it was interesting, so I bought two bamboo tubes and have been keeping them in the box ever since."

Her two older brothers are honest people. She would never open the trunk to look inside, whether it was locked or not. Her family didn't know what was inside, which is why she dared to say that.

Mu Lianrong said, "You know what, things from overseas are really good. The washboard, soap, and bubble solution you gave me are useful and interesting."

Xiao Yunying chuckled and said, "Yeah, I think it's pretty good too."

It's not something from overseas; it's something left by our ancestors, the crystallization of the wisdom of our ancestors.

I just don't know if it's part of the long river of history.

I can't explain it, I'm a little frustrated.

Xiao Yunbo put down the firewood and prepared to pour himself a bowl of water. Seeing the bowls of red things on the stove, he took one out and asked, "Little sister, what is this?"

Xiao Yunying shook the bowl; it had cooled and solidified completely. "The hawthorn cake I made is ready to eat."

"It's ready to eat, let me try it."

Mu Lianrong slapped his hand away: "Did you wash your hands after you came back from chopping firewood? You're eating with your hands. Use a spoon when you get back."

Xiao Yunying called out to the children that the hawthorn cake was ready to eat, and the children put down their things and carried the wooden basin into the yard.

The children gathered outside were getting restless, each one clamoring for their parents to let them play with the bubble solution.

Some parents, unable to bear the noise of their children, were also curious and tried to get close to Mu Lianrong to ask if they could let their children play for a while.

“These are things my daughter bought. Ask my daughter.”

Everyone looked at Xiao Yunying.

"I gave it to the children to play with. You should ask the children if they agree."

Everyone then looked at the children.

Xiao Chunlei pulled Xiao Yunying into the courtyard: "Auntie, was the bubble solution you bought expensive?"

"Not expensive."

"Can I collect coins for them to play with?"

Xiao Yunying nodded: "You can decide for yourself, but this is all the bubble solution we have for today. Once it's used up, it's gone. We'll have more tomorrow."

"I understand, thank you, Auntie."

Xiao Yunying led the children to wash their hands, and each of them shared a wooden spoon and a bowl to eat.

Xiao Chunlei pulled his younger siblings and the four children of the Luo family aside and discussed it for a while. He said outside the door, "Playing is fine. It costs two coins for a quarter of an hour to play with the bamboo tube, and five coins for a quarter of an hour to play with the net."

Once the price was announced, many people backed out.

"Five coins can buy more than a pound of dark flour."

"Let's stop playing. When we get home, Mom will steam buns and boil eggs for you."

The children disagreed, and the younger ones started crying and making a fuss.

Xiao Yunsong sipped his water: "That brat really dares to ask for it."

Xiao Chunlei calmly said, "My aunt spent a lot of money to buy this from overseas merchants. We can't possibly give it to you for free. If you think it's too expensive, that's fine. You can come and watch when we blow bubbles in the future. But it's impossible for us to give it to you for free."

The children became even more upset, and some of them sat on the ground and started rolling around.

An elderly woman came over with a three- or four-year-old child, took out two coins and gave them to him: "Give this to my grandson, the little one."

Xiao Chunlei filled a bamboo tube halfway with bubble solution and gave it to the child: "I'm afraid you won't be able to hold it and it will spill if I fill it too much. You blow on it first, and I'll fill it again after you finish blowing it within fifteen minutes."

Once that started, others couldn't resist the child's crying and took out coins.

Xiao Chunlei didn't collect every copper coin he saw. Instead, he made room to make sure there was enough water for the bubbles before collecting them.

Xiao Yunying smiled and said, "Brother, your son is smarter than you. He understands the principle of 'a rare commodity is worth hoarding' more thoroughly than you do. He will definitely be a business prodigy in the future."

Regardless of the dynasty, as long as it's a peaceful era and people have enough to eat and wear, money from children and women is the easiest to earn.

Xiao Yunsong chuckled and said, "Yes, my son will definitely have a bright future."

Xiao Chunlei's younger brother brought him a bowl of hawthorn cake, and the two brothers ate the hawthorn cake at the door while watching their "stall".
