Kaichi chose a piece of wood, cut it into a slightly larger size than A4 paper with a wind blade, and then used the wind to roll up a fine layer of iron sand to polish the edges of the board.

Their skateboard needs to be made of wood, so there is a lot of wood in the studio, and Jia Yi chose two pieces, all of which were cut into boards of the same size, with uniform thickness and smooth surface.

Li Weier watched Jia Yi's operation, the wooden board that had been made, and carefully stroked the polished smooth edge.

"Jiayi, are you all so delicate in making things?"

The edges of the wooden planks cut by the wind blade were originally very smooth, and Jiayi also polished out the arcs carefully, and each arc was almost identical, and the edges were also very neat, which not only required carefulness, but also showed that Jiayi's control was very good.

She didn't wait for Kaichi to answer, and exclaimed, "No wonder your skateboards are doing well, you can see from this detail." ”

Jia Yi just did it, but he didn't expect Li Weier to sigh so much, he has seen a lot of exquisite things in modern times, and he unconsciously has higher requirements when he makes it, especially he can also do magic, using magic for fine polishing is not only convenient, but also exercises his spell control, and there is also a sense of pleasure, or a sense of achievement.

Up to now, if it is said that the magic strength of Jiayi is not ranked among the students, but in terms of fine control over spells, none of the students in the entire academy can match him, including the senior students.

Jia Yi pursed his lips and smiled, and said, "This, as long as you practice more, there is no trick." ”

As he spoke, he finished all the boards, then took out a large piece of parchment, and cut the parchment into a piece slightly smaller than the board. These parchments are ordinary parchment, a piece of parchment layered, good craftsmanship can be split into 4 sheets, or even more, the outermost layer has the texture of parchment, the most precious, Jia Yi now uses all the remaining layers, these parchment paper is relatively cheap.

However, although the layered parchment paper is much lighter than the original, it is still very valuable, and it is still very bulky and smelly, and Jia Yi does not like it very much.

He cut the parchment paper and complained: "Isn't there paper now? Why hasn't anyone improved the paper, it's so inconvenient to use and it tastes so good." ”

Jia Yi has an urge to make paper, perhaps because mages are relatively rich, and because ordinary paper is not like parchment made of monster leather such as magic bells that can carry magic power, so although this world has already had primitive paper, there is no development, and it will take thousands of years to stop.

The paper of this world is already paper in the modern concept, which is pounded with plant fibers such as tree bark and then fished out. Unlike the Egyptian papyrus, although it is called paper, it is actually made by cutting the stalks of the sedge into thin slices, processing them, and splicing and hammering them, which is more similar to the ancient Chinese bamboo slips.

Jia Yi's hometown in his last life is near the origin of rice paper, and the hometown of rice paper still belongs to a city, although he does not know the specific production process of rice paper, but he has visited the rice paper museum, probably the process and raw materials still know. If you really take the time, although I don't dare to say that rice paper will be reproduced in this world, it is still possible to make a suitable white paper.

However, papermaking takes a lot of time, and it requires a lot of trial and error, and the requirements for manpower are also very high. Therefore, the so-called papermaking has always been only in Jiayi's plan, and it seems that it will always be planned.

"Isn't parchment bad?" Marche took the parchment in his hand and looked through it carefully, "next time you can choose the first layer of sheepskin, which is lighter and softer, these are the second layers of sheepskin, and the quality is worse." ”

They had never used white paper at all, so they felt that the current parchment paper was sufficient, and the ordinary paper was of poor quality and not easy to write.

Kaichi couldn't explain it to them, and if he copied the scroll, he had to use parchment made of Warcraft's leather, perhaps because of this, the mage who had mastered most of the knowledge inheritance in this world lacked the motivation to improve the paper process.

After cutting the paper, Jiayi took one and gave it to them, one for each person, and then said, "Next, everyone will cut the paper to this size like me, so that you can attach the parchment to this board and write, and you can write wherever you want." ”

As he spoke, Kaichi pasted the parchment paper on the wooden board, took out a pen, and made the appearance of writing and drawing.

Then he took out a ruler, stuck it on the top of the parchment, and said, "Let's make a table." ”

He left a place three wide on his head, drew a horizontal line with a ruler, and then drew a vertical line two fingers wide on the left, and wrote several rows of words on the vertical line, which are morphology, growth environment, growth cycle, flowering period, fruit period, edible value, medicinal value and so on.

When he was done, he showed it to the rest of the people: "Just like this, make a record book, write the name of the plant at the top, and then follow the left, and when we encounter any kind of plant, it's like filling it in." ”

"That's it, it's nothing. Erin muttered quietly.

At this time, there was already a rough classification of plants, such as their herbalism, the classification was almost the same as now, but there was no record of the growth environment, growth cycle and edible value like Jiayi, and a table like this was made, which looked clearer.

It's true, and there's no mystery left when it's written.

Before Jia Yi could speak, March began to hold grievances: "It's nothing, before Jia Yi made it, did you ever think about recording it like this, when you get to the botanical garden, it's difficult to even write." ”

Chester was very different from usual, not speaking on the side, quietly eliminating his sense of existence.

Li Weier came over to the round: "Although this is simple, it is really useful, and it looks very intuitive. ”

Jia Yi said with a smile: "This is really nothing, Zi Yao is willing to think about it, everyone can make it." In fact, our classification is still too simple, if we want to study plants in depth, we need to classify them more carefully, such as dividing plants into phylum, class, order, family, genus, species, etc., according to the relationship between plants, by comparing the morphological characteristics of each organ that makes up plants. In this way, it is easier to analyze the plant by comparing it with the same plant, deriving more useful information, and not finding a new plant and then having no clue. ”

The movements of several people slowed down, and they looked at Jia Yi with a confused expression, feeling that they had heard every word you said, but why was it so difficult to understand when combined?

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

Only Li Weier was thoughtful, and she was a little interested in the classification method that Jia Yi said, but Jia Yi himself was vague, and he had a little understanding of this aspect in the biology class, but after all, he had not learned it systematically, so it was okay to talk casually, but it was not good to be specific.

Li Wei'er and they made lattices on the paper, and Jia Yi raised his magic furnace and began to smelt metal and make iron shelves, which were used to clamp the paper on the wooden board.
