"Rubik's Cube?"

Xu Pang was undoubtedly the first time he had heard this term, he didn't know what it was, and the kind of object structure outlined on the drawings had never been seen before for him, with dozens of small parts in total, with strange and complex shapes, Xu Pang really couldn't see that these things could be assembled together.

"How? Can you do it?" When he asked this question, Song Yi didn't know the bottom of his heart, there are many reasons, the Rubik's Cube is an educational toy from the earth, which has been improved countless times in the past few decades, from materials to structure, and Song Yi considered that the manufacturing level of this world may not be high, so what he took out was actually a relatively primitive Rubik's Cube structure diagram.

But even the most primitive Rubik's Cube construction diagram, some of its internal parts are difficult to manufacture, such as springs, Song Yi doesn't know if it can be made in this kind of world background, and Song Yi is not clear about Xu Pang's ability.

As for why he wanted to build a Rubik's Cube, this is of course Song Yi's personal reason, now he has been in this world for a few days, but he is not very comfortable with everything, and the feeling of being too unfamiliar with everything around him makes him uncomfortable, Song Yi, who has a professional background in psychology, naturally knows that this is just due to a person's normal reaction after a sudden change in the living environment, and one of the ways to deal with this psychological condition is to find something that he is familiar with in the past.

The Rubik's Cube is one of the things that Song Yi is most familiar with on the earth, he has been in contact with it since middle school, unlike those players who follow the formula to compete in the shortest time to restore the Rubik's Cube, Song Yi has been pursuing the least number of steps to use his brain to calculate the Rubik's Cube, and Song Yi is the world record holder in this field, he once restored the third-order Rubik's Cube in seventeen steps, which is three steps less than the 'number of gods' calculated by the supercomputer.

This is the reason why Song Yi wants to make a Rubik's Cube, even if it is just to watch it in his room, it can make him psychologically comfortable, and he just thought that Xu Pang seems to be good at making all kinds of things, so he drew the structure of the Rubik's Cube overnight, and took this opportunity today to give the drawing to the latter to see if it is possible to make it.

But for Song Yi's problem, Xu Pang was a little speechless for a while, because he was not sure, first of all, he didn't even know what this was, and secondly, according to the text description on the drawings, Xu Pang felt that this was not just something that could be made with iron;

Qiao Yun and Father Xu Pang on the side watched the conversation between Xu Pang and Song Yi and didn't dare to interject, but they could see Xu Pang's appearance clearly, and they were very puzzled, what kind of thing was it that made Xu Pang feel so tricky, and what Father Xu Pang cared about was, why would the young master of the Song family take this kind of thing to his son? Xinan Town is not only a blacksmith shop, but there are more skilled people who have more skills, if there is anything special about Xu Pang, at most he has a habit of making all kinds of strange things.

At this time, Song Yi also sensed the concerns in Xu Pang's heart, and he said: "You don't have to worry so much, just say anything directly." ”

Hearing this, Xu Pang confessed: "I can't guarantee that I can make this thing, but... I'd like to give it a try. ”

"Then give it a try. Song Yi was not surprised by this answer, on the contrary, if Xu Pang directly replied that he could make it, there would be a ghost.

"You just said... You can just say anything, right?" asked Xu Pang.

"Hmm. Song Yi nodded.

Xu Pang swallowed his saliva, immediately flipped through the drawings, and said, "In fact, if we really want to create these parts on the drawings, we definitely don't have enough materials here." ”

"Tell me what you think. Song Yidao.

"First of all, it's called a corner block, right? You said you want to make it from a lighter material, and I don't think you can use the iron here, and although the iron is very hard, if it is made so finely, I am sure it will crumble. Xu Pang said.

"Then what do you think should be used?" Song Yi asked.

"With Xuanling wood. Xu Pang said: "If you want to be light, wood materials are an option, but ordinary wood materials are not as good as iron, so you can only use Xuanling wood." ”

"Xuanling Wood, what is that?" Song Yi had never heard of such a thing, but he didn't have to guess to know that this must be a kind of wood from this world, not something that is available on the earth.

"Xuanling wood is a kind of wood produced in the mountain and rock areas where the vitality is relatively strong, and among some steep cliffs, there is a tree with strong vitality that can grow, that is, the Xuanling tree, and the Xuanling wood is taken from the Xuanling tree. Xu Pang explained.

"Does it grow on a steep cliff or out of the soil in the cracks?" Song Yi asked, and if this is the description, there are several such plants on the earth.

But Xu Pang shook his head: "The difference between the Xuanling Tree and ordinary trees is that he grows from stones, and the Xuanling Tree does not rely on water to grow, but by eating stones and absorbing the vitality of heaven and earth. ”

This description surprised Song Yi incomparably, the tree that grew out of the stone didn't grow up on water? If it grew by eating the rock itself, then didn't it grow up eating calcium carbonate?

When Song Yi was a little surprised, Xu Pang continued: "It is precisely because it grows by absorbing rocks, so Xuanling wood is a kind of wood with high strength and excellent toughness. ”

"How expensive?" Song Yi asked the most crucial question.

"If I'm not mistaken, there was once a piece of Xuanling Wood weighing thousands of catties in the city that appeared at auction, and the final price was as high as six thousand gold coins. Xu Pang said.

"So expensive?" Song Yi was a little surprised, such a huge figure as six thousand gold coins turned out to be the price of a tree.

"Do you think this kind of wood should be used?" Song Yi suddenly felt that Xu Pang was obviously living a very poor life, but he had a tendency to lose his thoughts, as if he wanted to use gold to build a Rubik's Cube, which was already an artistic act, I am afraid that Xu Pang dared to make such a suggestion because he was the young master of Minghao Hall.

"Xuanling Wood is indeed a bit expensive, but it is the best choice. Xu Pang said, he glanced at Song Yi, and complained a little in his heart, you young masters in big families will also cherish money?

"Then you can estimate it directly, how many Xuanling Wood do you need to do this?" Song Yi pointed to the drawings in his hand and asked.

Xu Pang pondered for a while and said, "Estimate six to eight gold coins." ”

Song Yi breathed a sigh of relief, it seemed that the price was still acceptable, he still thought that he would have to start with hundreds of gold coins, if it was within the range of ten gold coins, he could still afford it now, so he would treat it as a work of art.

"Just use this kind of spirit wood. Song Yi gave an affirmative reply, and this sentence with understatement sounded a little terrible to Xu Pangda on the side, you must know that their blacksmith shop earns about four or five gold coins for a whole year, and Song Yi is worthy of being the young master of the Song family, and as soon as he opened his mouth, he squandered more gold coins than their annual income.

"Do you need any materials other than Xuanling Wood?" Song Yi asked again.

Hearing this, Xu Pang flipped through the drawings again, and this time he pointed out the drawings of the springs: "This is called a spring, and it can be automatically restored after being opened, right? ”

"Bullet gold?" Song Yi heard something he had never heard of before.

"Bullet gold is a metal that is fished from the deep sea, and after quenching to remove impurities and cooling, it will directly solidify on a certain form, and no matter how bent it is, it will quickly spring back to its original shape. Xu Pang explained.

"Memory metal?" From Xu Pang's description, Song Yi immediately thought of the memory metal on the earth.

"Memory metal? What is that?" Xu Pang was puzzled by the kind of thing Song Yi said, the reason why he knew all kinds of materials clearly was because he had been very interested in these things since he was a child, so he had been constantly collecting and learning about the information of various materials, even if he couldn't afford it, he had to know it, and what was this kind of memory metal that Song Yi said? He had never heard of it.

"Uh... It's nothing, I'm just talking nonsense. Song Yi explained in a coping manner, and then asked, "Is this kind of bullet gold also expensive?"

"The price is lower than that of Xuanling Wood, but to buy enough bullet gold, you need at least two or three gold coins, and other materials are not a problem. Xu Pang said.

"Then where are you going to buy these materials?" Song Yi asked.

"If you play gold, Xinan Town does not have it, and you can only buy it in the city, as for the Xuanling wood, there is a timber mill not far from here, I have been there a few times, and I have seen a piece of Xuanling wood there, which should weigh five or six catties, which is enough. Xu Pang said.

"It's in this bazaar?" Song Yi was suddenly very interested in this kind of Xuanling Wood, and he asked, "Can you take me over to see it now?"

"Are you going to see it now?" Xu Pang could see that Song Yi was a little impatient, this kind of appearance was too strange, just like when he heard about this material for the first time, he was full of curiosity, the young master of the Song family would also have this kind of curiosity?

Song Yi nodded, sure that he wanted to see this strange tree that grew up eating rocks and the vitality of heaven and earth now.

In this regard, Xu Pang could only turn around and say to his father: "Dad, I'll go out with Young Master Song Yi, at home..."

"Go ahead, just leave the affairs of the family to me, and you can take Young Master Song Yi with confidence!" Before Xu Pang finished speaking, his father immediately agreed, as if he was afraid that Xu Pang would not be willing to lead the way for Song Yi, but in fact, he was afraid of neglecting Song Yi, a young master of the Song family.

"In that case, let's go. Xu Pang didn't delay much, he put the drawings given to him by Song Yi in the store, and then walked out of the store, and Song Yi and Qiao Yun also followed him, and the three of them slowly walked to the other corner of the market.

And when Song Yi followed Xu Pang to the lumber mill in the market, far west of Xinan Town, in the Wang family.

Bang!

In the hall that should have been quiet, there was a sudden sound of breaking the teacup, and in the hall, several figures gathered, including Wang Jingshan, the head of the Wang family, and several elders including Wang Xu, and everyone was solemn at this time.

"Bastard! The Song family actually played us around!"

Wang Jingshan was almost angry at this time, he was originally waiting for the news of the slaughter of dogs outside Xinan Town, but he waited all night without responding, not only that, but the high-level family member who was responsible for contacting the slaughtering dog suddenly lost his news.

However, the real reason for Wang Jingshan's anger was because in the morning he was about to send someone to look for the slaughter dog and the family member outside Xinan Town, when someone suddenly sent something outside the door, and when Wang Jingshan saw such a thing, he immediately understood the truth of the matter.

Because it was the portable wooden card of the master of the psychic realm in the family.
