Jiayi chose a wooden board, cut it with a wind blade to a size slightly larger than a4 paper, and then used the wind to roll up a thin iron sand to smooth the edges of the wooden board.

Their skateboards require wood to be used as shells, so there are a lot of wood in the studio. Jiayi chose two pieces and cut them into wooden boards of the same size, with uniform thickness and smooth surface.

Li Wei'er looked at Jiayi's operation, and the already made wooden boards were carefully stroked and polished the smooth edges.

"Jiayi, are you doing things so fine?"

The edges of the wooden board cut by the wind blade are originally very smooth, and Jiayi has finely polished the curves, and each curve is almost the same, and the edges are very neat. This not only requires carefulness, but also indicates that Jiayi's control is excellent.

She didn't wait for Jiayi to answer and exclaimed: "No wonder you did a good job of skateboarding, you can see from this detail."

Jiayi just did it casually, but he didn't expect Li Wei'er to sigh that he had seen many exquisite things in modern times, and he unconsciously asked for higher requirements when making them himself, especially he also knows magic. Using magic to polish finely is not only convenient, but also exercises his magic control, but also has a sense of pleasure, or a sense of accomplishment.

Nowadays, if Jiayi is not ranked among the students, he is still not as good as his students in the school, but in terms of his fine control over spells, no student in the entire academy can compare with him, including senior students.

Jiayi pursed his lips and smiled, saying, "Just practice this, you can do it more, there is no trick."

While speaking, he made all the boards, then took out a large piece of parchment paper, cut the parchment into a slightly smaller piece than the board. These parchment papers are all ordinary parchment paper, and one piece of parchment is layered. Good skills can be split into 4 pieces, or even more. The outermost layer has the texture of parchment, which is the most precious. Jiayi now uses several remaining layers, and these parchment papers are relatively cheap.

However, although the layered parchment is much lighter than before, it is still valuable, and it is still very bulky and has a strong fishy smell. Jiayi doesn't like it very much.

He complained while cutting parchment paper: "Isn't there any paper now? Why no one has improved the paper? Parchment is really inconvenient to use and tastes so strong."

Jiayi had the urge to make paper, perhaps because the mages were relatively rich, and because ordinary paper was not like parchment made from magic bells and other magic leathers that could carry magic power. Although the world had primitive paper, it had not developed much, and it took thousands of years to stop.

The paper in this world is already a modern concept paper. Use tree bark and other plant fibers to pulp it out. Unlike Egyptian papyrus, although it is called paper, it is actually cut through the stems of papyrus into thin slices, and then pounded them after processing. It is more similar to ancient Chinese bamboo slips.

Jiayi's hometown in his previous life was near the origin of rice paper, and it was still the same city as the hometown of rice paper. Although he did not know the specific production process of rice paper, he still knew the general process and raw materials after visiting the rice paper museum. If he really took time, although he dared not say that rice paper was reproduced in this world, it is still possible to create a white paper for use.

However, making paper takes time and requires a lot of trial and error, and the manpower requirements are also high. Jiayi is a little afraid of trouble, which means that she complains every time she uses paper, and is too lazy to continue. Therefore, the so-called papermaking has always been only in Jiayi's plan, and it seems that she will continue to plan.

"Is parchment bad?" Maggie took the parchment in her hand and looked through it carefully. "Next time you can choose the top layer of sheepskin, which is thinner and softer. These are the sublayers of sheepskin, and the quality is worse."

They have never used white paper at all, so they feel that the parchment paper is enough now, while ordinary paper is too poor to be convenient for writing.

Kazuichi couldn't explain it to them, and if he copied the scroll, he had to use parchment made from Warcraft's leather. Perhaps it was because of this that the mage who mastered most of the world's knowledge inheritance lacked the motivation to improve the paper technology.

After cutting the paper, Jiayi took one for them, one for each person, and then said, "Next, everyone cut the paper to this size, just like me, so that the parchment paper can be attached to the wooden board and written, and you can write it at will wherever you go."

As he said that, Jiayi put the parchment paper on the wooden board, took out a pen, and made a look of writing and painting.

Then he took out a ruler and pasted it on the top of the parchment paper, saying, "Next, let's make a table."

He left three wide places on his head, drew a horizontal line with a ruler, and then drew a vertical line at the two fingers wide on the left, and wrote a few rows of words on the vertical line, namely shape, growth environment, growth cycle, flowering period, fruiting period, edible value, medicinal value, etc.

After writing, he showed it to the rest: "It's like this, it's made into a record book, with the plant name written at the top, and then go to the left. It's like filling it out which plant we meet at that time."

"That's it, isn't it?" Erin muttered in a low voice.

This is really nothing. At this time, there was a rough classification of plants. For example, their herbal medicine, and the classification is similar to that now. However, there is no such thing as Jiayi. It also records the growth environment, growth cycle and edible value, and a table like this was made, which looked clearer.

This is truly written and there is no mystery anymore.

Before Jiayi could speak, Machi began to feel unfair: "Nothing is nothing. Before Jiayi made it, have you ever thought about recording like this? When you arrived at the Botanical Garden, it was difficult to even write."

Chester is very different from usual. He doesn't speak while talking, quietly eliminating his sense of existence.

Li Weier came over to smooth things over: "Although this is simple, it is indeed quite useful and looks very intuitive."

Jia Yi smiled and said, "This is really nothing. Zi Yao is willing to think that everyone can do it. In fact, our classification is still too simple. If you want to study plants in depth, you need to classify more detailed classifications, such as dividing plants into phylums, classes, orders, families, families, genus, species, etc. According to the kinship between plants, it is possible to compare the morphological characteristics of the organs that make up the plants. In this way, through the comparison of similar plants, it is easier to analyze the plants, obtain more useful information, and you will not have any clues after discovering a new plant."

The movements of several people slowed down and looked at Jiayi with a confused look on his face. He felt that he had heard of every word you said, but why is it so difficult to understand when combined? You can understand them by picking them up separately, but in this context, it should not be the original meaning.

Thanks to the fact that the composition of different words in another world is different from that in Chinese, Gangmen and chrysanthemum are not the same thing.

Only Li Wei'er thoughtful and was a little interested in the classification method mentioned by Jiayi. However, Jiayi himself was vague. He had a little understanding of this aspect of biology courses, but after all, he had not learned it systematically. It would be okay to just talk about it, but it would not work in detail.

Li Weier and the others made grids on the paper, and Jia Yi raised his magic furnace and began to melt metal and make iron racks to hold the paper on the wooden board to fix it.
