According to Xia Duo's understanding, the design of the spell book can actually be divided into two layers: engineering and design, where engineering is specific manufacturing, and design refers to the design at the magic level.

Xia Duo designed the spell book, in fact, he was designing the architecture of the various functions of the spell book at the magic level, a bit like software development on the earth, and from this point of view, he was also considered to be thinly experienced.

In essence, the function of the spell book is all realized by the design of the magic level, and the material itself is only the carrier of magic, which may be important, but it is definitely not the core element.

In Xia Duo's planning, the spellbook can be roughly divided into functions such as energy circulation, external protection, special functions, permission management, and central links at the level of magic design.

The inner page is an external plug-in, he didn't count it into the spell book itself, as long as the corresponding energy port is left, the inner page can be added or removed at will.

At present, Xia Duo has completed the design of [Energy Circulation], [External Protection] and [Special Functions], and the reason why it is so fast is completely based on the Felder spell book and adopts a relatively mature scheme.

Among them, [Energy Circulation] is responsible for extracting energy from the magic net, and through the buffer of the energy core of the spell book, it supplies the consumption of various functions of the spell book;

[External Protection], as the name suggests, is the protection of various accidents outside the spell book, such as the reinforcement of the spell book itself, the response to external attacks or cracking, etc.;

[Special Functions] refers to control, levitation, positioning, etc., which are used for various functions of the spellbook itself.

As for the rest of the [Permission Management] and [Hub Links] -

The former needs to be redesigned, the latter is a link to various functions, and even a link hub is needed, and the [Hub Link] part cannot be completed until the [Permission Management] design is completed.

And the reason why he wanted to redesign the [permission management] of the spell book was actually that in the process of cracking the Felder spell book, he found that the Felder spell book only had an outer permission verification, and once it was cracked, it meant that the entire spell book was not defended.

As for the "modern" spellbook that Niya is currently using, its verification mechanism goes deep into the core, and even if the outer structure of the spellbook is cracked, it will not be able to obtain further permissions.

Although Nia did not reveal the specific permission verification mechanism of the spell book in her hand, Xia Duo guessed that her spell book is likely to have only one core permission, and once it is cracked, it is equivalent to no defense.

If Xia Duo wants to be more secure, then in terms of permission verification and permission management, it needs to be redesigned.

But in fact, there is a contradiction here:

Mages want their spell books to be as tightly encrypted as possible, but due to the particularity of mages, there are basically only two cases where spell books are obtained by others-

One is the loot after death (obtained by the enemy), and the other is given by oneself (juniors, friends, etc.).

In both cases, whether the spell book is encrypted or not, it doesn't really have much to do with the original owner.

Theoretically, it doesn't matter if it's not encrypted at all, after all, no matter how tightly encrypted it is, it can be cracked, it's just a waste of people's time.

This is like a mobile phone on the earth, the role of the boot password is not very large, and it can still be cracked if it is stolen.

Having said that, when he was on Earth, Xia Duo would still set a password for his mobile phone, and now, he will still redesign a more rigorous spell book [permission management] system.

Maybe there is also an idea of "not letting you get it easily", but there is a "lack of confidence" hidden in this idea.

Perhaps this is human nature, contradictory and complex.

……

Towards evening, Xia Duo closed his notes, stood up and moved his body, and before he knew it, he had been sitting for so long, and the design of the spell book was not yet complete.

In fact, the new design permission system cannot be designed all at once, and it must be verified from time to time and tested in conjunction with other functions.

Change as you write, change as you go.

However, today, Xia Duo is not ready to test, the Kingkiller has not yet receded, and he must always be in good condition in order to deal with emergencies at any time.

Like half a month ago, dragging his tired body to slay a dragon, he never wanted to do it again.

After a short period of exercise, Xia Duo sent a message to Nia, and after a while, the two met in the Arcane Garden. Xia Duo noticed that Nia seemed to be a little absent-minded, as if she had encountered something troublesome, so she took the initiative to ask:

"What's wrong? Could it be that something is going on in Severington? ”

"It's not."

Nia smiled apologetically, "It's that supply camp to the east, and those elves are making trouble again. ”

Hearing this answer, Xia Duo was a little surprised, he knew about the elves making trouble before, but he didn't expect it to happen again, "It's only been less than a month, it's already the third time!" What do you want this time? ”

On the previous two occasions, the elven refugees demanded that Savile provide them with sufficient food and rebuild their aesthetically pleasing dwellings.

Savile met the former, but sternly rejected the latter.

"They want tea, wine, and meat this time, maybe the supplies they carried with them when they fled have been consumed, but in their current situation, it is too much to make such a request!"

Nia confides in Shado about her dissatisfaction with the elven refugees, and if she regrets it, she will definitely ask the teacher to send someone else to deal with the elven refugees' troubles.

"If you don't, the elves may flock to Savile! But if you agree, so many elves, how can Savile have so much tea and wine to supply them, and I don't think the teacher will be able to reimburse this kind of expense! ”

Nia was very distressed now, she let out a long sigh and looked at Xia Duo, "What do you think we should do now?" ”

“……”

Is this an anti-guest, or is it a relapse? Xia Duo felt that this strange creature should not be let in, they were already refugees, and it was funny that they still wanted to enjoy it like this.

But now that it's been put in, it can't be driven away casually, and it can't be killed and killed, it's really embarrassing!

Xia Duo tried to come up with a solution, "Why don't you tell them that our supplies are also very limited, let them use the money to buy them, and the one with the highest price will get it?" ”

"It's okay, in fact, I really want to cut off all their food now, and see if they still want tea and wine! I think those elves are always going to be a nuisance if they go on like this, and they have to find something to do! Nia said with a determined expression.

"I agree with that! We'll have a meeting tomorrow and we'll talk about it, and now we'll finish dinner and go see Pamela! ”

"The Legend of the Fairy Tree"

"Hmm."
