In the next second, the sound of the gears rotating suddenly came from the square wooden box.

Then everyone saw that the wooden box began to move, and a thin layer of wood chips was unfolded on the side facing them. The wood chips were hollowed out with various patterns, and a window-like thing extended from the wood chips. The window displays A mountain and river with a miniature wooden carving.

The same is true of the other three sides, but the scene seen from each window is quite different.

It wasn't until the whole wooden box was opened that Lu Shaochuan found out that it was a secret box.

As long as there is water falling from the top, the mechanism inside will open, revealing the "window". If you look inside from the window, you will see different scenery of mountains and rivers.

"It's amazing!" The girl was pleasantly surprised by this gift. She had never seen such a powerful gift before, and hurriedly turned around and hugged Su Shuangjiang's thighs and screamed, "Brother! This is amazing!"

Not only the girl was amazed, but even Lu Yan, who was used to seeing good things, was full of praise when looking at this mechanism box.

"Where did you get it from? It's too beautiful." Although the carvings are ordinary, this mechanism is quite cleverly set up!

Lu Yan wanted to buy a collection, but he couldn't possibly steal his daughter's birthday present, right?

However, he heard Su Shuangjiang say with a smile: "Uncle, I made this, and it is estimated that this is the only one in this world." Of course, if someone imitates it, that's another story.

Hearing this, Lu Yan didn't believe it at first, but after seeing Su Shuangjiang's eyes, he had to believe it.

If someone else really made it, it's impossible that he hasn't heard of it by now, so... Su Shuangjiang is really telling the truth.

Thinking of this, he began to think about what he could use to exchange gifts with his precious daughter.

Grab is unlikely, but barter is always possible, right?

Lu Shaochuan wanted to touch the mechanism box, but he was afraid that he would accidentally break it, and the girl would be angry and cry.

The water that has just been poured in is not only the key to the opening of the mechanism, but when the water flows through it, it just forms a picture of the mountains and rivers with the carved mountains and rivers, and the whole still scene comes alive in an instant.

However, the amount of water in this glass of water is not much, and soon the water flows down to the bottom and into the large basin.

Without the flow of water, the trap box began to turn again and again, and it closed again and turned into the previous box.

Su Shuangjiang pointed to the small hole and half-squatted and said to the girl, "You can get someone to make an automatic water flow device, so you can keep watching."

As soon as he said these words, Lu Yan was awakened immediately.

"Yeah! That's a good idea!" Lu Yan hurriedly called to find someone.

Watching others take the water glass and pour it down again and again, Su Shuangjiang sat silently on the sofa, waiting for them to get tired of playing.

This thing took him a lot of time. If it weren't for the lack of time, he would like to make the carving a little more carefully.

However, his craftsmanship is not very good, so forget it.

After watching it over and over again, Lu Shaochuan finally calmed down. He leaned over to Su Shuangjiang and wondered how he made this trap box.

"How to do it? It's very simple, there are gears in it, one ring is connected to the other, using the power of the water flow..." Su Shuangjiang explained to him, but after he finished speaking, he found that Lu Shaochuan's eyes became empty.

Don't look at Su Shuangjiang's words so easily, but hearing those words in Lu Shaochuan's ears is no less like listening to a book from heaven.

He suspected that Su Shuangjiang was playing tricks on him, and deliberately didn't make it clear.

Su Shuangjiang was very helpless, and dragged him to the edge of the box. While pouring water, he pointed to the extremely hidden gear inside and continued to explain to him.

But even after this second explanation, Lu Shaochuan still didn't quite understand.

There are gears... well, get it! Utilize the flow of water...you know that too! Then...then what???

Looking at her son's stupid expression, and at Su Shuangjiang's unsure helplessness, Ming Youwei, who had been observing them, suddenly said, "Shuangjiang's grades should be good, the final exam is coming soon. Are you ready?"

At this time, there is only more than a week left before the final exam. Although there is no need to take the liberal arts, it is said that the difficulty will be quite high this time.

For Su Shuangjiang, it doesn't matter whether he is prepared or not, he is already reviewing the knowledge points for the second semester of high school.

When his parents asked about the exam, Lu Shaochuan was a little flustered, especially when his mother asked about Su Shuangjiang's grades, he didn't know how to answer.

"My grades are okay, I'm not very worried about this final exam." Hearing Su Shuangjiang say this, Lu Shaochuan looked at him with a subtle look.

If he hadn't known that Su Shuangjiang was on a shift, he would have believed it.

He poked Su Shuangjiang quietly, stop talking nonsense at this time.

Unfortunately, Su Shuangjiang didn't understand Lu Shaochuan's meaning, instead he glanced at him suspiciously and touched his poked waist.

"Oh, is it! The grades are really good, my son's grades can only be said to be average, hey, I'm so worried! Every time I ask him for a tutor, I get angry!"

Speaking of this, Ming Youwei became furious and immediately glared at her only son.

Lu Shaochuan touched his nose and turned his head in embarrassment. It wasn't that he didn't study well, he just didn't want to.

Not only him, but also Ke Yu, except that one of them is liberal arts and the other is science.

He knew very well that he wanted to inherit his family's company. He was also brought to the company by Lu Yan, and he also had a set of opinions on managing the company.

But always feel like...everything is boring.

"Maybe it's not enough interest, because there is no direction, so there is no strong interest in learning, because if there is no interest in learning, you feel like you can't learn anything." This is why many people say that interest is the driving force for learning.
