Not to mention vanilla ice cream, any cold drink, in the wasteland is a luxury that only the powerful can afford.

Liu Ziru purely treats vanilla ice cream as an ice cube and sticks it to the bruised area of his arm. Christina, on the other hand, cherished the spoon and scooped the ice cream scoop in the bowl.

"Don't you use bottle caps?" Christina, who was enjoying herself with vanilla ice cream, asked.

"No caps, this." Liu Ziru took out a piece of RMB from his pocket and said like popular science, "RMB, the legal tender of the People's Republic of China, is within the territory of the People's Republic of China, and you can only use it if you want to buy things." ”

"Is it a currency backed by national credit?" Christina asked.

"You know?" Liu Ziru was a little surprised, and he said, "That's right, it is indeed guaranteed by national credit." ”

"It's great, we've wanted to launch this currency for a long time, but unfortunately, it hasn't worked out yet." When she said the first half of the sentence, Christina's eyes flashed with small stars, and when she said the second half of the sentence, her tone contained loss.

However, the loss was fleeting, and she looked at the prosperous streets and said firmly, "If it works here, we can do it there!" ”

Liu Ziru encouraged, "Come on! ”

He would not say that the reason why the New California Republic wants to introduce a credit currency has nothing to do with the radiation canteen that is now under his control.

Perhaps, some old drunkard thinks that by doing this, he will be able to cheat with some pieces of paper without handing over the precious map.

After asking this question, Christina, remembering the questions she had saved when she was in the store, asked them all.

Liu Ziru said as he walked, answering them one by one, although it was inevitable that some common sense would be popularized, but he still tried to be as concise as possible. When the two of them walked to the subway entrance, they had basically finished speaking.

When she went underground, Christina didn't show any discomfort. For various reasons, there are quite a few people in the wasteland who live underground and live like rats.

Although Christina lives on the ground, she is an explorer and burrows in the ground.

Compared to the dark and damp underground cave, where I don't know what the hell is, the bright, dry and clean environment of the subway station is already the highest level of existence in the cave.

Because of the reasons introduced by Liu Ziru, when she passed the security check, nothing happened. Although she is also quite concerned about the scanning equipment at the security check, she is more concerned about the people who walk by her.

"Why are there so many people? Why so many people? Christina looked at her curiously like a child.

Although some people around thought she was strange, no one came to disturb her. Although she was dressed in fancy clothes, although she behaved strangely, she was white-skinned.

Perhaps it has something to do with recent history, no matter where a person comes from, as long as he has a white skin, he can get a lot of preferential treatment in China.

Therefore, China has also become a place of yearning for many European and American dicks. It's in their opinion that Asian women are too small, and they are suspected of loli controlling fetishness.

After waiting for a while, the subway silently drove into the station. People who have already been an official subway are accustomed to this. Christina, however, feels the technological content behind this.

"Is it all so developed here? Everyone is holding a beep boy, and the subway is silent? Christina asked, looking at the subway and looking away, most of them looking down and playing with their phones.

"That's pretty much it. However, this is not a beep boy, it is a mobile phone. Although it has many functions, it is not possible to accurately view one's own health information, nor can it measure the amount of radiation. The vanilla ice cream that Liu Ziru had in his pocket had turned into a soft mud with the coolness released. Christina's ice cream was eaten and thrown away before entering the subway.

"Here you go." Liu Ziru didn't know where to take out a piece of chewing gum and handed it to Christina.

Under Christina's questioning gaze, he threw another piece of gum into his mouth as a demonstration.

Christina has a lot to do. However, because she had just eaten vanilla ice cream, the sweetness of the gum was mostly covered by the vanilla ice cream aftertaste.

She chewed and chewed for a while and asked, "Why do we eat car tires?" ”

This......

Liu Ziru stared at Christina for a long time, speechless. Indeed, it is true that both chewing gum and tires are rubber. But there are very few people who feel like they're chewing a tire while eating gum.

However, following this line of thought, the thick tires seem to chew with a sense and taste......

Wait, stop!

Liu Ziru hurriedly terminated his fantasies. If you continue to think like this, you should be led astray.

"The speed of the subway is a bit fast, and the first time you sit it, it may be a little uncomfortable for your ears. It is said that chewing gum can be slightly better. Liu Ziru said.

"Oh, so there are so many things to say about chewing tires." Christina sighed, looking out the window and after a dozen seconds, said, "I know why my ears are so uncomfortable." ”

"Why?" Liu Ziru asked rhetorically.

"It's easy." Christina subconsciously put her hand on her waist and touched it, only to find that the gun was placed in the cafeteria and not brought out.

"Look, imagine I'm holding a gun in my hand right now." Christina made a gesture to hold her gun.

"And then?"

"The subway we're on now is actually a bullet in a gun. And the tunnel through which the subway passes is a very long barrel. When a bullet passes through the chamber, it squeezes the air, and of course the subway does the same. It's normal for us to feel uncomfortable sometimes! ”

Liu Ziru pondered for a while, the logic that Christina said was correct, but the example given was really inappropriate. Fortunately, she was allowed to put the gun in the store in advance, otherwise she would have brought it out and brought it out in public for example. Even if you don't go off the gun, you can't explain it when you go into the duty room with the police uncle.

"You are now taking Rail Transit Line 1, and there is Bowenmen Station in front of you, so passengers who get off the train should be prepared in advance. Passengers transferring to Metro Line 5 should get off at Bowenmen Station. ”

"It's time to get off." After Liu Ziru finished speaking, he was ready to get out of the car. He was afraid that if he continued to talk to Christina, he would not be normal.

It stands to reason that he'd seen so many visitors from the wasteland, and it shouldn't be like this. But the little girl in front of him made him feel extremely difficult to deal with.

Is it that you are too shallow? Or is she too skilled?

Is it a good choice to hire her as a clerk?

The exit of the subway station is inside the mall, and you can spend money in three steps and two steps. I have to say that as long as you have money, such a setting is still very intimate.

The mall was brighter than outside, but Christina didn't show any more surprise. She seemed to be surprised that the groove was empty, and she followed Liu Ziru really calmly.

Because Liu Ziru rarely comes to the mall himself, he usually changes his clothes online. After looking at the sign next to the ladder for a long time, he took Christina upstairs.

"Tell me which one you like?" After Liu Ziru finished speaking, he took Christina and walked up in the mall.

Compared to others walking around the mall slowly, two people can be regarded as extremely fast. Even if this floor is not small, it took the two of them less than ten minutes to walk through.

"Nothing in the picture?" Liu Ziru asked.

Christina shook her head.

Liu Zi felt a slight remorse in his heart, what did he do when he took her out to buy clothes on a whim. It's not that she can't wear her outfit, even if she is seen by ordinary customers in the store, people will only think that this is the store's characteristic role-playing.

I just bought two sets online in the store, and it is not beautiful to wait for a day or two of express delivery.

However, it's already coming, so buy it.

Liu Ziru, who didn't understand women's clothing at all, took Christina, who didn't understand women's clothing at all, and went around the mall again.

Compared with Liu Ziru, Christina's speed of adaptation is faster. Perhaps, this is one of the elements that explorers and naturalists need.

After all, in this world, there will always be something that will not be likable. If you don't like it and don't know if you're not interested, then you're not a naturalist.

As Christina explored these women's garments, her eyes suddenly lit up. She saw her favorite thing – books.

She strode over, picked up a copy, and flipped through it. Although the book is very thin, the quality of the paper inside is very high. The clothes printed on it are almost exactly the same as the real thing here.

Liu Ziru looked at Christina's appearance with some puzzlement, he couldn't understand why Christina, who was obviously not particularly interested in clothing, was so concerned about thin brochures.

And, most importantly, why look at a brochure when the real thing is right in front of you?

When Liu Ziru was puzzled, a black uncle with chocolate-colored skin crossed his eyes, probably wondering about something too, and there were question marks on his head.

"Why are you looking at this brochure so seriously? Obviously, there are real things here. Liu Ziru asked.

Christina took the pamphlet, her eyes wide and surprised, "This is the pamphlet?" ”

"Or else?" Liu Ziru really wanted to slap himself unconscious, I really don't know what this big brother is looking at for so long.

"None of the propaganda I've ever seen is like that, it's the kind of ...... with Pip-Boy painted on it," Christina said a little weakly.

"That's a nuclear war pamphlet, it's been gone for decades. Do you like books? Liu Ziru asked.

"Like! Of course I do! Christina exclaimed.

"Follow me." Liu Ziru said.

This is a large shopping mall with a strong complex, and the second basement floor is a very large bookstore.

It stands to reason that in these years, it is becoming more and more difficult for physical bookstores to operate. It is very difficult not to make a large-scale profit, even not to lose money.

Although, there are a lot of new books on the market now, and there will be no online version at all.

However, even if the publishing house does not launch an online version, those enthusiastic book lovers will either scan or hand-type and upload it to the Internet with their spontaneous sharing feelings.

Besides, even if you actually buy a physical book, it is actually a better choice to buy it online than a traditional brick-and-mortar bookstore. Because, when you buy online, the actual purchase price is only six or seven percent of the list price.

However, it's all here, so let's go check it out. I don't know if the girl behind her can read books full of Chinese. I guess I can't understand it.

Even if it is the original book in English, it is estimated that she will not understand much except for those older books.

After all, language is constantly evolving. It's like a Chinese, if you go back hundreds of years, you can't communicate well with the people at that time.

Liu Ziru's ability to communicate with the wasteland residents without barriers is because he has been in contact with these people since he was a child, and over time, he has learned everything with the influence of this language environment.

Besides, don't look at the wasteland wasteland that it calls it. In fact, people from different parts of the wasteland have very different languages.

For example, on the East Coast and the West Coast, for example, Boston and Detroit, the accents are much, much different.

Having been cultivated in such a smoky language environment since he was a child, Liu Ziru's speed of learning foreign languages and his sense of language are very good. Once, because of his youth, he accidentally triggered the incident of crying English teacher.

If you want to blame him, you can't blame him, who makes the female English teacher who has just graduated more vulnerable.

Christina looked at the dazzling array of books, like some woman, seeing luxury.

She was really like a water-starved sponge, as if she wanted to absorb all the knowledge.

As Christina was flipping through a book like a wolf, Liu Ziru asked, "Can you understand it?" ”

Christina shook her head, "You can analyze it slowly with the knowledge of cryptography and linguistics, but I can't understand it now." ”

"Let's go, I'll take you somewhere." Liu Ziru said.

Christina obediently followed behind Liu Ziru, who looked at the signs in the different reading areas above his head, and did not walk in until he saw the words of the child.

He picked up a box of pinyin cards, held it up and said, "I think you can start with this." ”

Christina turned out to be the pinyin card in Liu Ziru's hand, and looked back and forth several times, and suddenly became excited.

"What's wrong again?" Liu Ziru frowned.

"It's amazing!" Christina exclaimed loudly as she looked at the dazzling array of preschool products.

The people around looked at her, and she didn't need Liu Ziru to remind her, she realized that she was too rude, and hurriedly made an apology posture.

"I'm sorry, but when I went to the library before, there weren't so many people......" Christina whispered, "I have a cult of knowledge there, and the library is a holy place, and people who have not received divine revelation are not qualified to enter it at all...... The church has a monopoly on knowledge, and there is almost no blank in terms of early childhood education......"

Liu Ziru thought about the difference between that side and this side, and once again forgave Christina.

Like a magician, he took out a box of things and said, if you want to learn the language here, I guess this thing is very useful.

Christina took the box and asked, "What is this?" ”

Liu Ziru smiled and said, "Chinese character cookies." ”
