Lan Xin has been shy lately!

It's not about real money, but about real money, Lan Xin can be said to be a real little rich woman, and the trust fund set up by Lanzhou Kai in her name has reached nine figures!

All Lan Xin lacks is gold coins that can be exchanged for food and TV...... Compared with Xixi, a big landlord who has saved more than 20 gold coins, Lan Xin really doesn't have a single gold coin now!

It's all to blame for the Spring Festival!

During the Spring Festival, due to Lan Xin's great improvement in her final exam results, Lanzhou Kai and Wu Jingjing became tolerant of Lan Xin, and in addition to urging her to finish her winter vacation homework, they never asked her to study and exercise. Moreover, on such a big festival, Lan Xin followed her family to eat and drink, go around to play, and the comfort of getting something for nothing completely overwhelmed the little girl!

The happy little days made Lan Xin inert. When Wu Jingjing noticed that something was wrong and urged her to exercise and read, Lan Xin gags, stubbornly changed the topic, or played tricks, unwilling to exercise.

In terms of educating children, Wu Jingjing sometimes needs to sing blackface at home. Seeing Lan Xin like this, she once again executed the previous "gold coin tactic", Lan Xin had to use gold coins to watch TV!

Moreover, if there are not enough gold coins, Lanzhou Kai and Wu Jingjing will not bring Lan Xin with them when they go to the restaurant outside for a big meal!

Lan Xin still wants to be lazy, she saved a small amount of money by writing winter vacation homework a year ago. Just two days ago, on the day Xi Xi came back from her hometown, Lan Xin comfortably nestled at home and watched TV for a day, and her gold coins were completely consumed!

Without gold coins, although Lan Xin doesn't have to worry about the crisis of food shortages for the time being, she can't watch TV, and she doesn't like to read, at home, Lan Xin can only be bored!

Yesterday was really a day of suffering......

Today, Lan Xin's flexible little head thought of the previous experience of watching TV at Xixi's house, so she was overjoyed and sneaked to Xixi's house to play.

It just so happens that today Yang Luoqi and Nan Zhaoyu also came to play with Xixi, and Lan Xin can also rub some delicious snacks prepared by Yang Yi for the children!

……

Xixi didn't know what her little friend was thinking, she was happily showing Yang Luoqi and Nan Zhaoyu what she had just learned.

I saw that on the floor of the side hall, Xi Xi jingled over a lot of equipment, such as a large plastic cup, a small plastic cup, a large bottle of mineral water, and even a mother's electronic scale, and a broken red brick.

"Xixi, why did you bring bricks here?" Nan Zhaoyu asked as he sat on the floor with his legs crossed, a little confused.

"Because we're going to experiment!" Xixi said with a chuckle.

"What kind of experiment?" asked Nan Zhaoyu tirelessly.

"Oops! I'll tell you!" Lan Xin shouted, she ran upstairs in a hurry, ran to take down the "Cool Science Experiments" in Xixi's bedroom, and proudly showed it to Nan Zhaoyu, "Look, this is the book, there are a lot of interesting experiments in it!"

Lan Xin came to Xi Xi's house to see that Yang Yi had done some experiments with Xi Xi, but with Lan Xin's character, she only looked at it curiously, and did not have a strong interest in trying it herself like Xi Xi.

However, at this moment, she felt as if she had learned these experiments, and she proudly showed off to Nan Zhaoyu and Yang Luoqi.

I have to say that the bright and colorful cover color of this book is still very attractive, and Yang Luoqi stretched out her hand expectantly: "I want to see it!"

Xi Xi hurriedly stretched out his hand to stop it, and said a little anxiously: "No, hey, you can't watch it now!

If you watch it in advance, wouldn't it be like the magic trick has been revealed, and their own experiment has been figured out, then it will be unattractive to do this experiment yourself!

Xixi still wants to behave in front of her friends!

"Okay then!" Yang Luoqi withdrew her hand and sat down obediently beside Xi Xi, waiting for her to do the experiment, in fact, Yang Luoqi was also very curious about the experiment that Xi Xi had to do on the floor with so many equipment.

Not only them, but Xiao Yu sat curiously on the side, waiting to see her sister's performance.

In the past, my sister's friends came over, and Xiao Yu rarely could play with them, but now Xiao Yu moves freely, even if the "castle" can't trap his footsteps, so, seeing my sister and their lively here, Xiao Yu naturally came over.

Yang Luoqi likes Xiao Yu very much, no, she didn't get the book, after retracting her hand, she reached out and hugged Xiao Yu next to her in her arms, and her little hand rubbed it on Xiao Yu's smooth and fleshy little face.

Feel good thief!

Xiao Yu also seemed to enjoy it, in the arms of the young lady Xiangxiang, she squinted her eyes very comfortably, grinning and didn't know what she was laughing at.

"That's it, we're going to pour water into here!" Xixi diligently did the experiment alone for everyone to see, the little girl carefully grabbed the big plastic bottle of mineral water, and poured it into the big plastic cup, "Well, that's pretty much it, can't pour too much!"

Then, she took the large plastic cup containing more than half a glass of water to the electronic scale, which quickly showed the weight.

"I know, it's 0.53 kilograms!" Nan Zhaoyu hurriedly shouted, he was quite expressive.

Xixi took off the plastic cup and put the small brick on it.

"This is 0.3 kilograms!" Nan Zhaoyu shouted.

"We're going to put it in the water!" When Xixi was about to put the bricks into the plastic cup, she suddenly remembered something, she raised her little head, and said excitedly to her friends, "You have to pay attention, it's super amazing!"

At this time, even Lan Xin poked her head over with a curious expression.

I saw Xixi carefully put the bricks into the water of the plastic cup, and suddenly, many bubbles bubbled up on the surface of the bricks, like a bead curtain, rising to the surface of the water one by one!

Of course, this gurgling sound is so small that it is almost inaudible.

But it still made the children look straight.

"Wow! This stone spits bubbles! like a frog!" Nan Zhaoyu exclaimed in amazement.

Yang Luoqi had a different opinion, she let go of the hand holding Xiao Yu, leaned over, supported the floor with both hands and watched, and then said: "It's not like a frog, it's like a small fish, and the little fish will spit bubbles like this!"

"Could it be that there are small fish in it?" Nan Zhaoyu asked in surprise.

"Hehe, it's not spitting bubbles, and it's not a small fish!" Xixi happily popularized science to his friends, "I said that it's because there are many small holes in the bricks that we can't see, and it will suck water in, and then the air inside will run out, so there will be small bubbles!"

"That's it!" Yang Luoqi listened to Xixi's explanation, and together with the other friends, she felt very magical to look at this small brick that could spit bubbles.

Of course, at this time, a small head also poked out next to Yang Luoqi, she turned her head and saw Xiao Yu who was about to join in the fun.

When Xiao Yu saw that he had been discovered, he immediately looked at the young lady and grinned.

"Oh, Xixi, your brother is so cute!" Yang Luoqi was amused by Xiao Yu.
