On the Seven Towers

Xiao Chen took out a space bag from his arms. This is the only space treasure in the school so far, and it was left by the killed temple priest.

Although it is not as cool as a space ring or bracelet, it is better than an enchanted suitcase. And finally let Xiao Chen find the feeling of the magician in the story who can summon and wave away all the treasures.

The space bag keeps a magical space of about one cubic meter in a volume the size of a purse. Unlike the legendary space ring that can be operated with just a thought, the things in the space bag need to be taken out by hand.

And its strangeness is that the length, width and height of the things placed in it are all reduced to about one-fifth of the original, and the weight is less than one percent. But after putting the hand in, it still feels like a 20-centimeter-long bag, and one hand can reach the bottom of the bag.

Xiao Chen thinks this is because the rules of the space bag only work on dead objects, so the hand is immune to this shrinking effect.

He searched for a while and took out a mug with a handle, as well as paper and pen. These things suddenly became larger in the short time they passed through the bag.

This is a very strange experience. People who don't master it well often can't hold it at this moment and let it fall.

He put the mug on the coffee table, and then put the paper and pen in front of Javier, "Your Highness Javier, try to think about it. What does this cup look like when you look at it from six angles, front, back, left, right, up and down? You can't move the cup, you can only rely on your imagination. Then draw them."

Javier obediently began to observe the cup, and then began to draw. It can be seen that he has learned to draw. Even if he used a ballpoint pen for the first time, the graphics he drew were not bad. But after he drew for a while, Ye Zi began to laugh.

Javier drew the side of the cup that he could see correctly, and there were various errors in other directions. For example, in the view above, you can still see the round hole in the middle of the handle. Or from the handle side, the handle is still bent.

After he finished drawing, Xiao Chen said, "See if it's right for yourself."

Javier picked up the cup and turned it around, and his face quickly turned red.

"I'm sorry. But I just can't figure out what it should look like from these directions." Javier whispered.

Xiao Chen took the cup and comforted him: "It's okay, this is not your problem, but it involves a kind of talent, which we call spatial imagination. Because the magic model itself is a three-dimensional figure. If you can't understand it from the drawing, you naturally can't use your mental power to outline the model in your mind."

Hearing that he lacked talent, Javier's face turned pale: "But, but I want to be a great magician, so that I can eliminate the imperialists for my father. I, I can't be a magician?"

Xiao Chen said: "Don't worry, it's just that I lack spatial imagination. I just have a set of toys here to exercise this."

Xiao Chen took out a bag of snowflake toys from the space bag. These toys are not made of plastic, but made of wood, and are smaller than the originals. These snowflakes are made by carpenters in Floro Town, specially used to make spell models. There are not only flat eight-slot snowflakes, but also two interlaced, cross-shaped connecting pieces, or corner pieces bent at specific angles, which can build more accurate models than traditional snowflake building blocks.

However, this kind of building blocks is only used for demonstrations by the mages in the capital. It can only express static structures and cannot show the dynamic changes in the model. But in any case, it is much easier to understand than the structure drawn on paper.

Xiao Chen and his team used 3Ds Max software in their laptops to study the model. Just like every time Li Jia comprehends a new spell, he will go back to the base to build the model and make it into an animation so that he can popularize it in school.

Javier obviously has never seen this kind of toy. He is still a child and picked up a few building blocks to play with them.

Xiao Chen demonstrated by building a cube and rotating it in his hand.

"Try to build them into various shapes every day, then turn them around in your hands and think about the shapes at each angle, and you will gradually improve."

"You can play with Sister Ye Zi when you have time. When you get used to it, your spatial imagination will naturally improve."

Ye Zi rolled her eyes at Xiao Chen, but still touched Javier's head, "Don't worry, I'm an expert at this."

"Okay." Javier quickly built a strange shape in his hands. The child was fickle-minded, and his emotions had long since recovered. He asked, "What about the fire-starting technique? If I have to practice for many days to learn it, My mother and teacher will definitely be disappointed. Sir Xiao Chen, do you have a faster way? "

"It's not difficult." Xiao Chen took out dozens of snowflake building blocks, and with a thought, they floated up, arranged and combined in the air, and finally plugged together to form two ignition models, one is the starting state and the other is the ending state. Under the control of Xiao Chen's mental power, the two models rotated in the air together, "Look carefully! Now you need to imagine how the model slowly changes from the left side to the right side. "

Javier stared at the model in a trance.

"I have never understood why the magicians here don't develop these auxiliary means to learn magic." Li Jia said.

"I believe there must be. However, it may not be used to teach children. Judging from the degree of pickyness of the magicians here in selecting successors, I am afraid that children who cannot understand graphics by themselves are not worth educating at all, right?" Xiao Chen kept the two models rotating while talking to Li Jia, which was a manifestation of the ability to distract himself.

"I thought that magic was something that only a few people could master. But the more I came into contact with it, the more I found that those few barriers did not seem to be that difficult." Li Jia said again.

"Then why are there so few magicians?" Ye Zi asked, "I've heard magic apprentices complaining that magic is too difficult to learn several times. These people should be qualified, right?"

"Have you ever thought about what kind of course it would be if magic was considered a course?" Xiao Chen smiled and said, "If magic is viewed from a mathematical perspective, the structure of the model is solid geometry, right? But the components that make up the structure are magic words, which is language. For example, this ignition model is roughly a sphere with three ridges, and there are two magic words involved. In other words, for a magic apprentice to learn this magic, he must be able to use his mental power to write two variant forms of magic words "fire" and "flash", and combine some lines to piece them into a sphere, and finally make these components move until the end. I think it is difficult to do this without a junior high school education."

Ye Zi nodded in agreement.

"More powerful magic is much more complicated, so how can there be so many magicians in this world full of illiterate people?" Xiao Chen asked back.

"But our school is different..." Ye Zi just opened his mouth and was interrupted by Xiao Chen's gesture of silencing. He signaled Javier in front of him with his eyes.

As expected, Javier came out of that state and woke up.

"Thank you! Sir Xiao Chen. I think... I think I did it." He stretched out his hand, and sparks appeared on his fingers.
