Everyone, upon hearing the question, immediately looked at each other. Finally, Yan Hua took out a pocket full of loose banknotes.
"Based on our observations during this period, the money in this world is different from the money in our world. This red one is the largest denomination, similar to our gold. The green one is decent. In short, different colors have different values. However, in this era, silver and gold are still valuable, but gold is no longer a circulating currency. It seems that in our time, very few people directly paid with gold ingots, so I think this is quite easy to understand," Chen Xi explained very seriously, like a tour guide from modern society.
Qi Yu listened and nodded.
Then, he thoughtfully held the hundred-yuan banknote and examined it: "Since silver and gold are still valuable, why don't they directly use silver and gold for payment like in our time? Or use copper coins, but instead, they have to add these banknotes, which will then be divided into various grades. Besides, gold and silver can still be exchanged for money. Why go through this extra step?"
Qi Yu couldn't understand why it was an unnecessary step.
Si Qing didn't understand much either, but he wasn't particularly curious about these things.
Chen Xi put her hands on her hips: "Who knows why this world is like this, but I don't really care. What I care about now is that the clothes sold in this world are super interesting. Don't you think their clothing and dressing style in this world is very simple?"
Men don't need to be particular about anything. Long hair doesn't necessarily mean having a beard, and the requirements for hairstyles are very simple, even to the point of shaving their heads.
As for women, they can wear dresses that expose their arms, and the shoes are very beautiful, with very classic movements. They don't need to wear layers upon layers like them.
This kind of layering not only makes dressing and behavior inconvenient but also makes ordinary people's daily routines difficult.
Of course, it's a bit easier for immortals like them.
"It's indeed very convenient. The clothes I conjure with magic are all in line with the aesthetic standards of this world," Qi Yu said, standing up. "The dresses here range from long to short, in all sizes, and exposing the legs looks quite beautiful. Most importantly, the shoe styles are no longer limited to boots; besides boots, there are many other styles that look very beautiful. Although I don't understand why they have so many strange things, I have to admit that these strange things can be handled by ordinary people without magic or spiritual power, which is indeed very convenient for ordinary humans, especially those with two wheels."
The thing Qi Yu was referring to was the bicycle in the human world.
Upon hearing this, everyone showed interest and left the screening room to observe the streets. They finally focused their attention on electric bikes and bicycles. There was also a type of vehicle called a motorcycle, which they had indeed seen, but it moved too fast.
It wasn't conducive to their careful observation.
Qi Yu and Si Qing conjured identical sportswear. Then, the two of them, in the same posture, with their hands tucked into their sleeves, squatted under an old locust tree, studying a parked bicycle.
Qi Yu reached out and gently touched the wheel. The wheel immediately spun, and then it got stuck on the lock.
Si Qing curiously turned it backward. The wheel also got stuck on the lock, unable to move forward or backward.
"So, this thing is quite magical, but the material doesn't seem to exist in our world. The chain is easy to handle, but the key is this handlebar-like thing. How can this thing maintain balance? Ordinary people can balance on it and ride freely without using spiritual power. How is that achieved?" Qi Yu reached out and squeezed the wheel of the bicycle in front of him.
"I've never seen this thing before. It doesn't look like steel or fabric, so what is it?" Si Qing also squeezed the wheel.
The group had no idea how the wheel was made.
Chen Xi touched her chin, recalling her memories, and said, "Based on the memories I obtained after returning to my master, this wheel is made of rubber. As for how rubber is made, I'm not too sure. It seems that the memories of this person don't contain knowledge about this aspect."
Qi Yu stood up: "In that case, we should go and learn about this knowledge. Where is the fastest and most comprehensive place to learn things in this world? Is it still a study hall?"
But they hadn't seen any study halls on their journey.
"The place with the most books here seems to be the library, on the street ahead," Chen Xi said, touching her chin. "However, the person whose memories I peeked into didn't like to study much, so there are almost no memories about the library, only its name. Let's go and take a look together."
Si Qing agreed wholeheartedly.
As a law, he had an obligation to absorb new knowledge and other cultures to gradually enrich the order of this world. Although this world didn't seem to be the world he was familiar with and controlled, they would return someday.
They might even return soon, so before that, they had to find their companions as quickly as possible and firmly absorb the knowledge of this world.
With this thought, they arrived near the so-called library in the blink of an eye. The library entrance was right in front of them. However, they couldn't just go in; they needed a membership card for registration, and there were restrictions on reading time and borrowing methods.
Qi Yu found it too troublesome and finally used his spiritual power. The group entered directly and swaggered in.
There were still people studying and reading in the library. It was inconvenient for them to appear in public or use magic to levitate books and read them.
So, after entering the library, they found a few spots and huddled together, silently waiting for the ordinary people working busily in the library. From day to night, until the library was locked, they finally appeared and, with the speed of reading a thousand words at a glance and possessing photographic memory, quickly flipped through all the books in the entire library.
Si Qing even more rapidly collected all the knowledge from these books into his mind.
Qi Yu was not idle either. While they were collecting the knowledge, he opened the computer used for registration and recording nearby and began to study this high-tech device that he had never encountered before.
