In fact, Xixi's experiment, in addition to showing the magical condition of bricks absorbing water, also asked the children to calculate how much water the bricks absorbed in the end.

However, this kind of calculation problem is not very attractive to Nan Zhaoyu and Lan Xin.

After a while, Nan Zhaoyu was excitedly urging Xixi to perform more experiments for them.

......

In the evening, Nan Zhaoyu and Yang Luoqi were going home, their respective fathers came to pick them up one after another, Yang Luoqi was a little late, and Yang Guo rushed over after class.

Yang Luoqi reluctantly said goodbye to Xi Xi and Xiao Yu, and was about to go home with her father, but Yang Luoqi just stepped out of the door of the villa with her front foot and shrank back.

"Dad, can you wait a minute, I'm going to borrow a book from Xixi!" Yang Luoqi remembered the colorful book she had been thinking about in the morning, and after finishing speaking, she turned around and ran towards Xixi.

"What books to borrow?" Yang Guo was a little puzzled, "Qiqi, what book do you want to read, let's pass by the bookstore later, and Dad will buy it for you!"

Yang Yi stood aside and smiled, and said: "You really can't buy this book, our publishing house is ready to introduce it, and now we have just found someone to translate it, and we are still proofreading the process, it just so happens that I also have one more sample book here, let Qiqi take it back and read it!

This is just a piece of cake for Yang Guo, he is an associate professor who teaches English at the university!

Over there, the two little girls muttered and discussed for a while, Xixi turned around and ran to the side hall where she had put her things just now, and generously handed the book they had read in the morning to Yang Luoqi.

"Thank you, Xixi, I'll give it back to you after I finish reading it! I'll take it to the school to give it to you, okay?" Yang Luoqi thought for a moment and proposed.

"Yes, you can read it for a long time, hehe, this book is so fun!" Xixi and her friend laughed sweetly.

......

Yang Yi found that after Xixi's two visiting friends went home, Lan Xin was still in their home, she and Xixi ran down from upstairs, and were chased upstairs by Xiao Yu, and her heavy little feet stepped on the stairs, making a knocking sound.

"Walk slowly, don't fall. Yang Yi was about to make dinner, walked to the stairwell, called out, and asked by the way, "Xin'er, are you eating at our house tonight?" If so, uncle will cook your rice. ”

Lan Xin poked her little head out of the upper edge of the stairs from the stairs, and asked happily, "Is it really possible?"

Yang Yi smiled slightly and said, "Don't worry, this time my uncle invited you to eat." However, when you start school, you won't be able to, and you'll have to study and exercise hard!"

Lan Xin didn't answer Yang Yi's question just now, but the little girl's cheers had already told Yang Yi her answer: "yes! Uncle Yang is really a good person! Hehe, Xixi, I can eat at your house!"

That's a bonus!

In fact, Lan Xin didn't want to achieve this goal, she was reluctant to go home, more because she was too bored at home. Where is it so interesting like Xixi's home, in addition to Xixi's interesting talking, there is also a fun little Yu Yu who often comes to join in the fun!

Lan Xin and Xixi, the two little girls, giggled, you chased after me, ran into Xixi's room, and then closed the door, and the two of them jumped on the bed together!

I don't know what makes them laugh so happily, Xixi leaned forward and leaned back with laughter, hugging the quilt and rolling into a ball.

After making trouble for a while, Lan Xin proposed with great interest: "Xixi, let's go watch TV!"

This may be her ultimate goal, she can't watch TV at home, but she can come to Xixi's house to watch TV!

Then you can watch TV for a long time, and from now on eating, Lan Xin remembers that now Jiangnan TV has children's sitcoms to watch! After eating, you can continue to watch TV, and at that time, the Central Children's TV will play cartoons that she and Xixi both like to watch!

However, as soon as Xixi heard that she wanted to watch TV, she hurriedly waved her hand, shook her head and said, "No, no, Xin'er, I can't watch TV now!"

"Why?" Lan Xin asked in confusion.

"Because I'm going to save it! When I've saved up a hundred gold coins, I'll ask me to save it in the bank. Xixi said wistfully.

Lan Xin was still confused: "Deposit in the bank?"

Xixi is happy to popularize this knowledge with her friends: "Xin'er, let me tell you, our money can be deposited in the bank! I just told my father yesterday to deposit my New Year's money in the bank!"

I saw Xixi get up from the bed, go to the top of the cabinet at the head of the bed, take out her treasure chest, open it, take out the deposit slip, and show it to Lan Xin.

"You see, I saved 12,000 yuan with Baba and Baba Baba said that after I wait for three years, I will have an extra 990 yuan!" Xi Xi said excitedly, "If I save the gold coins as well, then I can also have new gold coins!"

"Huh, so powerful?" Lan Xin asked in surprise, "Then if you have a hundred gold coins, how many new gold coins can you have?"

Xi Xi snapped her fingers, and calculated, last time her father listed to her how much interest she could have for a hundred yuan, it seems to be more than two yuan?

"Two, right?" Xixi felt that the decimal point was too complicated, so she simply gave a rounding answer.

"Two?" Lan Xin's eyes lit up, and she said excitedly, "Then if I have a hundred gold coins, don't I have to exercise?

Xixi tilted her little head and thought about it, she felt that something was wrong?

But Xixi didn't figure out the key - Lan Xin seems to regard annual income as daily income!

"Okay, it should be!" Xixi nodded hesitantly.

"Then I also have to save money, I, I want to have two hundred gold coins!" Lan Xin seemed to have a soaring IQ, she proudly snapped her fingers and counted for Xi Xi, "So that I can have four gold coins, so that I can watch TV and eat at your house!"

"But two hundred gold coins are hard. Xi Xi pouted and said, "I'm tired today, I helped Baba pull the weeds, and I earned two gold coins!"

"No, I want to earn two hundred gold coins!" Lan Xin was full of energy at the moment, shouting excitedly. The little girl felt that if she was willing to invest now, she would be able to lie down and eat and drink in the future!

"Xixi, I can tell your father, I will also help my father pull weeds and work in the future, can he let my mother give me gold coins as well?" Lan Xin took Xixi's hand and asked expectantly.

"I don't know...... Xixi always felt that something was wrong, but she couldn't think of it, so she could only say in a daze.

"Let's go ask your father!" Lan Xin didn't want to be lazy at the moment, and raced against time to pull Xixi downstairs.

"Okay then, ask me Baba, I know what Baba knows!" Xixi also frowned and followed behind her little friend, she felt that it was still wrong, but she couldn't think of anything wrong.

Asking Dad is the best way, Dad is powerful and omniscient!

After a while, Yang Yi's crying and laughing voice sounded in the kitchen: "My God, who told you that gold coins can also be deposited in the bank?"
