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

Liu Ziru purely treated vanilla ice cream as ice cubes and stuck it to the bruised position of his arms. Christina cherished the spoon and digging the ice cream balls in the bowl.

"Don't you need a bottle cap?" asked Christina, who enjoyed her vanilla ice cream.

"No bottle cap, use this." Liu Ziru took out a RMB from his pocket and said with popular science, "The RMB, the legal currency of the People's Republic of China-Henan, is within the territory of the People's Republic of China-Henan. If you want to buy something, you can only use it."

"Is it a currency launched with national credit as a guarantee?" Christina asked.

"Do you know?" Liu Ziru was a little surprised. He said, "That's right, it is indeed guaranteed by national credit."

"It's great. We have long wanted to promote this currency, but unfortunately, we haven't succeeded yet." When saying the first half of the sentence, little stars flashed in Christina's eyes, and when saying the second half of the sentence, her tone contained loss.

However, loss was fleeting. She looked at the prosperous streets and said firmly, "Since this place can be done, we can definitely do it there too!"

Liu Ziru encouraged, "Come on!"

He would not say that the reason why the New California Republic wants to launch a credit currency is not unrelated to the radiation canteen that is now under his control.

Perhaps, an old drunkard thought that if he did this, he could use some paper pieces to cheat food and drink without having to hand over a precious map.

After asking this question, Christina remembered the questions she had left when she was in the store, and asked them all.

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

When he walked into the ground, Christina did not show any discomfort. For various reasons, a considerable number of people living underground, living like mice.

Although Christina lives on the ground, she has also been drilling holes because she is an explorer.

Compared to dark and humid caves, which are unknown, the bright, dry and clean environment of the subway station is already the highest level of existence in the cave.

Because Liu Ziru introduced that nothing happened when she went through the security check. Although she also cared about the security check scanning equipment, she cared more about the people passing by her.

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

Although some people around her thought she was strange, no one came to disturb her. Although she was wearing strange clothes and her behavior was strange, she had white skin.

Perhaps it is related to modern 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 for many European and American losers to yearn for. In their opinion, Asian women are too young and are very suspicious of lolita-controlled children-obsessed.

After waiting for a while, the subway drove silently into the station. People who have already become officials are used to this. However, Christina felt the technological content behind it.

"Is it so developed here? Everyone holds a beep boy in his hand, and the subway is silent?" Christina asked as she looked at the people who looked out of the subway, and most of them lowered their heads to play with their phones.

"It's basically the case. However, this is not a pizza boy, but a mobile phone. Although it has many functions, it cannot accurately view its own health information, nor can it measure the amount of radiation." Liu Ziru's vanilla ice cream in his pocket turned into a sludge-like shape with the coolness released. Christina's ice cream was eaten before entering the subway and threw it away.

"For you." Liu Ziru took out a piece of chewing gum from somewhere and gave it to Christina.

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

Christina followed suit. However, because she had just eaten vanilla ice cream, the sweetness of the gum was covered by the aftertaste of the vanilla ice cream.

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

this……

Liu Ziru stared at Christina for a while and was speechless. Indeed, it was true that chewing gum and tires were rubber. But few people would feel that they were chewing tires when eating gum.

However, following this idea, the thick tires seem to be very touching and tasteful...

Wait, stop!

Liu Ziru quickly ended his fantasy. If he continued to think about it, he should be taken a step aside.

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

"Oh, it turns out that there are so many things to say about chewing tires." Christina sighed, she looked outside through the window, and said ten seconds later, "I know why my ears are uncomfortable."

"Why?" Liu Ziru asked back.

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

"Look, imagine I'm holding a gun now." Christina made a gesture of holding a gun.

"Then what?"

"The subway we are taking now is actually the bullets in the gun. The tunnel that passes through the subway is a very long barrel. When the bullet passes through the barrel, it will squeeze the air, and of course the subway will do the same. We in the bullets will feel uncomfortable sometimes, which is very normal!"

Liu Ziru thought about it for a while. The logic that Christina said was correct was correct, but the examples she gave were really inappropriate. Fortunately, she asked her to put the gun in the store in advance, otherwise she would take it out and give an example in public. Even if she didn't get the gun out of fire, she would not be able to explain when she entered the duty room with the police uncle.

"You are now riding on the rail transit Line 1, and Bowenmen Station is ahead. Passengers who get off the bus should be prepared in advance. Passengers who transfer to the rail transit Line 5 should get off from the Bowenmen Station."

"It's time to get off the bus." After Liu Ziru said that, he was about to get off the bus. He was afraid that if he continued to talk to Christina, he would become abnormal.

Logically speaking, he had seen so many visitors from wasteland, so he shouldn't have done this. But the little girl in front of him made him feel extremely difficult to deal with.

Is it because her own Taoism is too shallow? Or is it because her skills are too deep?

Is it a good choice to recruit her to be a clerk?

The exit of the subway station is in the mall, and you can spend it in three steps. I have to say that as long as you have money, this setting is still very considerate.

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

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

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

Compared to others who slowly walked around the mall, the two of them could be considered extremely fast. Even if this floor is not small, it took less than ten minutes for the two of them to finish it.

"No one likes?" Liu Ziru asked.

Christina shook her head.

Liu Zi felt a little regretful in his heart. He took her out to buy clothes on a whim. Why did she do that? She couldn't wear her clothes. Even if she was seen by ordinary customers in the store, she would only think that this was a special role-playing role.

I just bought two sets online in the store, and it was still a pleasure to wait for a day or two to deliver.

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

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

Compared to Liu Ziru, Christina adapts faster. Perhaps this is one of the elements needed by explorers and naturalists.

After all, in this world, there are always things that are not likable. If you don’t like them and don’t know them, you will not be a naturalist.

When Christina explored these women's clothing, her eyes suddenly lit up. She saw her favorite thing - books.

She took two big steps, picked up one and read it. Although the book was very thin, the paper quality inside was very high. The clothes printed on it were almost exactly the same as the actual objects placed here.

Liu Ziru looked at Christina with some confusion. He couldn't understand why Christina, who was obviously not particularly interested in clothing, was so concerned about the thin brochure.

Moreover, the most important thing is that the real thing is right in front of you, why do you still need to read the brochure?

When Liu Ziru was confused, a black uncle with chocolate skin passed by his eyes, perhaps he was also confused about something, and his head was full of question marks.

"Why do you look at this brochure so seriously? There are clearly physical objects here." Liu Ziru asked.

Kristina held the brochure and opened her eyes wide and said in surprise, "Is this a brochure?"

"Or what?" Liu Ziru really wanted to slap himself out. I really don't know what this big brother has been watching for so long.

"The promotions I have seen are not like this, they are all the kind of guys who paint a slut..." Christina said a little weakly.

"You are a nuclear war anti-war brochure. It has been decades since here. Do you like books very much?" Liu Ziru asked.

"I like it! Of course!" cried Christina.

"Come with me." Liu Ziru said.

This is a large shopping mall with strong comprehensiveness, with a very large bookstore on the second floor of the underground.

Logically speaking, in this year, it is becoming increasingly difficult to operate a physical bookstore. Not to mention large-scale profits, it is difficult to lose money.

Although there are many newly launched books now, there will be no online version at all.

However, even if the publisher does not launch an online version, those enthusiastic book fans will upload it to the Internet with their spontaneous sharing sentiment, either scanning or hand-tamping.

Besides, even if you really buy physical books, it is actually a better choice to buy online than traditional physical bookstores. Because, when buying online, the actual purchase price is only 60% to 70% of the price.

However, since I have come, let’s go and take a look. I don’t know if the girl behind me can understand books full of Chinese. I guess she can’t understand them.

Even if it is the original English book, she probably won’t understand too much except those older books.

After all, language and writing are constantly evolving. Just like a Chinese, if you go back hundreds of years ago, you will not be able to communicate well with the people at that time.

Liu Ziru's ability to communicate with wasteland residents was because he had been in contact with these people since he was a child. Over time, he learned how to educate the language environment.

Besides, don’t look at the wasteland and wasteland, in fact, people from different parts of the wasteland have very different languages.

For example, on the East Coast and the West Coast, like Boston and Detroit, people's accents are much worse.

Since childhood, Liu Ziru has been in such a smoky language environment. His speed and sense of language are very good at learning foreign languages. He used to accidentally triggered the incident of crying in English teachers because of his youth.

If you want to blame him, you can't blame him. Who makes the newly graduated English female teacher more vulnerable?

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

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

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

Christina shook her head, "You can use cryptography and linguistics to analyze it slowly, but now I can't understand it."
