Although a few mortise and tenon buckles are inconspicuous, for Xing Jie and Li Sishi, who are familiar with the technique, such a hint can be said to be obvious.

With a few clicks, the black book in Li Sishi's hand had already formed a cylinder. The gold back plate in Xing Jie's hand forms a pattern similar to the sun.

Such a thing was amazing to look at, but it couldn't be combined with the cylinder made of the book.

In this way, it was as if a set of books had become two completely different things, and they were presented in front of the two of them in a big way.

"The craftsmanship of this book is quite exquisite. Xing Jie took the black cylinder and looked at it for a while, and then praised it.

"But what should you do with this 'Golden Sun', it can't be a combination failure, right?" Li Sishi scratched his head and asked.

"How do I know, at first I thought I might have made a mistake. However, the mortise and tenon joints of these gold backplates are very consistent. It's possible to get one wrong assembly, but it's not like all twenty-five are wrong. Xing Jie shrugged his shoulders and said.

"Let me see, the cross-section of the cylinder composed of this book slip is about the same as the inner diameter of the 'Golden Sun'. If you put it on like this, it seems to fit quite well. But it's too funny, isn't it? The material is quite precious, but it only makes a golden sunflower, and it is not as delicate and beautiful as my son's making. Li Sishi said with a smile.

Xing Jie pursed his lips, feeling a little crooked. Ever since little Amy gave birth to a big fat boy to this bastard, Li Sishi has become a dazzling maniac, and when he sees people, he says how cute and smart his son is. But that's a good point, the little guy showed amazing talent at a young age. At the age of three, he was able to play the twenty-fourth-order Luban lock alone, which made Zhang Fang and the others feel extremely hot, and they all shouted to accept apprentices.

However, he was attacked first by a few shameless old monsters from the eight places and directly accepted as closed disciples, which made Zhang Fang's senior brothers quite sad. However, what adventures Li Sishi's son has is all about the next generation, so let's not mention him first.

Just thinking of this, Xing Jie and Li Sishi were stunned when they looked at the twenty-five gold backplates in their hands. It's not because I thought that Li Sishi's son could play Luban lock, but because I thought that the Mo family once had a very similar Qizhi-type mechanism. However, because it was too difficult, it did not spread, but there has always been a map in the Mo family.

Although there are only a dozen wooden sticks, it is possible to achieve a very complex three-dimensional composition by using mortise and tenon buckles. But it's only fifteen roots, and it's already very brain-burning. If these 25 gold backplates had been designed in the same way, and had not been assembled, the amount of work would have been large today.

"Try it?" Xing Jie asked with some uncertainty as he looked at the gold backplate in his hand.

Li Sishi was also unsure, after all, there were too many three-dimensional compositions that might be erected by twenty-five gold backplates!

……

Zhao Minghua and they were miserable, they didn't expect Xing Jie and Li Sishi, who were in confusion, to be so tyrannical. What is it that in order not to disturb their work, they have prepared a week-long survival experiment in the wild?

Oh my God, it's the coldest time in Northern Europe, and everyone is kicked out of the castle gates with all the necessary survival tools!

And all the housekeepers and maids in the entire castle were frightened during this time, and the two gentlemen who could have been said to be amiable didn't know what happened during this time, and turned into powder kegs that exploded at one point. After seeing several sets of exquisite tea sets smashed to pieces by the two angry people, the butler Edward was distressed and almost pumped over.

With the passage of time, the time to discuss with Han Zhongxuan has come.

When he arrived, Zhao Minghua, who had already dared not come out, and those housekeepers and servants felt that they were saved. Because the only one who can make the tiger back down is the lion.

It's just that they were happy too early, and when they saw that Han Zhongxuan was also quickly addicted to it, Zhao Minghua and they all had the idea of wanting to die.

A few days later, Natasha and Hank arrived. The steward of the castle gave them a numb and pitiful look, and then mechanically ordered the servant to bring coffee and sandwiches into the study.

This is quite rude in hospitality etiquette.

But when Natasha and the others pushed open the door of the study, they didn't bother to say anything, and they were stupid. Because she is very familiar with this place, but in her memory, the original bookish and palatial study was full of smoke at this time, with cigarette butts piled up into mountains and wine bottles thrown into a pile. As for Xing Jie and Li Sishi, their eyes were blood-red, their beards were unkempt, their hair was messy, and the clothes on their bodies hadn't changed for an unknown amount of time, exuding a very bad smell. Han Zhongxuan, who pays great attention to personal appearance at the site, is a little better, but there is no good way to go.

On the table, there are fifty sticks that look very familiar.

"You guys are crazy to tear down all the precious books?" Hank's eyes almost popped out when he saw those things.

But no one paid attention to him, because the three of them were lying on the sofa with their mouths open, looking up at the ceiling, their hands kept making various movements in the air, but their mouths were open and closed and they didn't know what they were saying.

"Oh my God, you're committing suicide in a slow way. Even if you study these books, you have to keep a good environment, this room full of smoke will smoke people to death!" Natasha didn't say a word, she directly opened the heavy velvet curtains, and directly pushed open the window.

When the cold wind poured into the study, Xing Jie, who was thinly dressed, jumped up with a snort.

"Oh, Farke. Hurry up and close it, you want to freeze to death, right?"

"Shet! Lao Tzu's eyes are going blind. Close the window!"

Xing Jie's scolding did not make Natasha stop, but opened another window without hesitation.

"Mr. Han Zhongxuan, you didn't call me here just to see your decadent appearance, did you? I still want to further study the discovery on the last discovery on the Phoenix Island......

Natasha's grumbling voice echoed in the study, but she unexpectedly didn't hear Xing Jie's cursing. This made her feel a little unbelievable when she was opening the window to breathe, but when she looked back, she found that Xing Jie, Li Sishi, and Han Zhongxuan were looking at her honestly.

"Did I say something wrong?" said Natasha, somewhat unnaturally.

Xing Jie and the three of them didn't answer, but after glancing at each other, the light in their eyes became brighter and brighter.

"Haha, I see! I said, how could there be two more, it turns out that this is what it means!" Xing Jie and Li Sishi rushed directly to the edge of the desk after speaking, grabbed the books and the gold back plate and began to assemble them.

"What are you talking about?"

"Natasha, do you know that you are really a good general? This luck is about to catch up with Xing Jie! Opening a window can suddenly open up things that we can't figure out for a while. Do you know what your actions mean? Young's double-slit experiment!"

What the double-slit experiment is, Natasha certainly knows. But what does it have to do with Xing Jie? How do archaeological excavations have anything to do with wave-particle duality? Are these things composed of books and gold backplates so exaggerated?

Han Zhongxuan hugged Natasha, who was still confused, kissed her hard, and then came to the desk in the same way, and worked with Xing Jie and them with an excited face.
