Stone age

Han Zixin pitied the bastard in his heart. He dragged her by her school bag and made her enter a supermarket. 

"Come, I will show you how to shop with this card," Han Zixin said as they entered the supermarket. "Did your mom tell you some kind of number combination about these cards?"

An Xiulan paused for a moment and then nodded her head. "She did!"

"Then, buy me candies," Han Zixin replied. 

"What can we possibly buy with this card?" An Xiulan asked again, still could not believe that these cards could help them buy things. 

"Anything you would want to buy," Han Zixin sighed. This black card has no upper limit for shopping. He didn't know why she wasn't told about the benefits and dangers of having a black card in high school. 

Were her parents too careless with her to give her this back card?

 Do they know she could be taken advantage of by any student in school for holding such a luxury item?  

It was fine if it was some other student but his deskmate? She was dumb, naive and gullible. Those students would swallow her whole if they saw such a thing with her. 

"Little blockhead, you are not allowed to use this card to buy something for anyone," Han Zixin clearly told her. He was certain that if he didn't teach her, she was going to be taken advantage of. 

Oh lord, why did she always give him tension! 

"Does this mean only I can buy things with this card for myself and things for someone else can't be bought?" An Xiulan asked. This logic was confusing. Therefore, she was waiting for him to explain to her. 

Han Zixin took a deep breath and said, "You can. In fact, you can buy anything with this card. It's universal. It is accepted at any store, domestically or internationally."

An Xiulan mouth formed into an 'O'. 

He went on saying, "But it's not safe to use it for others. You will be taken advantage of by other students. There are some students in our school that use rich students like you to pay for their expenses."

'Am I rich?' An Xiulan wanted to ask but forgot when he continued saying. 

"Those students are so good at being good friends that you won't notice when they will take advantage of you. So, stay away from people who are friends with you because of money or status," Han Zixin said. All the people he was acquainted with only knew him as a tyrant or a gangster. None of them knew that he was a young master like Lu Xuan. 

Why did Lu Xuan hold respect and a place in students' hearts even though he was no better than Han Zixin? 

It was because Lu Xuan was the young master of the Lu family. His bad reputation was overshadowed by his financial status and handsome face. 

"Better to not show others that you are rich. And don't bring cards to school again," Han Zixin informed her. " Instead, set up a We chat Pay account or something similar to that for paying for your expenses."

At this moment, he wasn't her rival or the person she argued with the most. He was simply a deskmate who understood her more than anyone.  He was genuinely concerned about his deskmate and understood how naive she could be. 

How bad would it sound when people would say that Big Boss Han's deskmate is taken advantage of? 

No, he couldn't let this girl soil his hard earned reputation in the school. 

Yes, he was doing everything for his reputation, but because he cared for some dumbhead. 

An Xiulan looked down at her feet, her inferior complex hitting her again. "I don't understand what you are saying."

Even after coming to this world for so many months, she didn't understand most of the things. She was such an embarrassing figure. Most of the time, she would keep her questions all to herself because people wouldn't answer without showing how ignorant she was. 

She accepted the fact that she was ignorant and perhaps even stupid. But why couldn't her questions be answered without making her feel inferior? 

Han Zixin looked around and then he found an empty table and chair in the supermarket. He dragged An Xiulan by her bag once again and made her sit on the empty seat and then took the seat next to her. 

"Where is your phone?" Han Zixin asked. He was going to do what he couldn't before. "Look carefully at what I'm doing." 

An Xiulan gave him her phone and on his orders, she carefully looked at what he was doing on the phone. 

"Do you know how many functions phones have apart from using it for calling and texting?" Han Zixin asked. He kinda liked how she wasn't always lost in her cellphone in school. She would rather read books in the library than waste her time on Weibo or We Chat or making those lip sync videos like most teenagers these days. 

"I don't use my phone much, "An Xiulan said. 

.

"Of course, you don't," Han Zixin scoffed. "That's why you are still living in the stone age."
