Magus Tech Chapter 281: Printed circuit board and magic pattern cracking
Same night.
Laboratory, main laboratory.
Li Cha was sitting in front of the experiment table, working hard.
Many candles were lit, emitting dim yellow light, reflected by multiple mirrors, making a certain area on the table extremely bright. Li Cha was in this area, looking at the papyrus scroll on the The transcribed magic patterns of the three magic pattern props obtained from the auction.
Each transcribed magic pattern is very complicated, and it looks so dense that it makes people dizzy. Li Cha's eyes were focused, studying the direction of the magic pattern, thinking about the method of cracking the magic pattern, so as to absorb, use and improve it.
Generally speaking, in the current world, magic patterns are difficult to decipher, not to mention that there are systematic ways to decipher them.
However, Richard will not limit his thinking to the present, and will contact some relevant knowledge on the modern earth.
In Li Cha's view, the magic patterns in the current world are very similar to the circuits on the modern earth, and they have many similarities. Even if it cannot be completely equated, some knowledge on the circuit can be used.
On the modern earth, the development of circuits has always been accompanied by encryption and cracking, just like a spear and a shield-the circuit designers of some precision instruments will try their best to encrypt circuits to prevent them from being copied by competitors, and Competitors will work hard to crack and get what they want.
In the development of circuits, circuits are constantly being miniaturized, and large circuits are gradually becoming miniature circuits. The wiring between electronic parts is printed on the insulating board by printing metal wires, and becomes a printed circuit board, namely Printed Circuit Board, referred to as PCB.
For PCBs, there are many encryption methods, such as sealing glue, painting, buried holes, blind holes, etc.
The cracking of PCB's multiple encryption methods is called copy board, and the methods emerge in endlessly and in various ways. In fact, as far as technology is concerned, cracking PCB is not a question of whether it is possible, but a question of whether it is worthwhile.
In other words, there is no PCB that cannot be cracked, it just depends on how much you invest. If the investment is too much and the gain outweighs the gain, it is better to change another valuable PCB to crack it.
And looking at the magic patterns of the current wizarding world from the perspective of circuit cracking on the modern earth, everything becomes simpler.
Although the texture of the magic pattern is dense and cumbersome, it is still incomparable to the complicated PCB on the modern earth. If the circuit difficulty of the modern earth is at the level of a smartphone, then the magic pattern of the current world is at the level of a shaker or a big brother.
The encryption method is very basic, such as deliberately adding or hiding a certain line, or hiding the real core and functioning magic patterns among many wrong and meaningless magic patterns.
This is enough to deal with ordinary plagiarism. Even if it cannot be completely eliminated, it can make the cost of most plagiarists extremely high.
For example, it was originally a simple magic pattern that produced a paralyzing arc, but the magic pattern master expanded it into many useless magic patterns. Repeatedly drawn.
In this way, the plagiarists have to spend a lot of effort to successfully imitate the magic pattern. And in this process, as long as one of the lines of the core magic pattern is accidentally drawn wrongly, the entire magic pattern will fail, enough to collapse.
However, the same encryption method is not enough for Li Cha.
Under the light, Li Cha looked at the lines on the scroll, his eyes flickering. Put your finger on it, slide it slowly, divide the area, calculate the combination of some magic lines, and quickly conceive the specific method of the test.
The next moment, take out the white jade piece from the space iron ring, and quickly draw it according to the lines on the papyrus scroll.
"Shushasha..."
The white jade piece was processed in a short time, and compared with the original magic pattern, it has a lot less lines.
Li Cha tentatively input mana, the white jade piece vibrated and shattered with a "click".
"Well...it seems that the magic lines in A2 and D4 areas can be eliminated."
After one failure, Li Cha was not discouraged, took out a new piece of white jade and started drawing again, and carved a completely different magic pattern on it.
Holding the second piece of white jade, Li Cha tentatively poured mana into it, and then it shattered again with a "click".
"The magic lines in B3 and C5 areas can also be excluded."
As Li Cha said, he took out the third piece of white jade, and processed, portrayed, and tested it again.
With a "click", it broke for the third time.
Then the fourth, fifth, sixth...
The white jade pieces were broken one by one, and when Li Cha took out the eleventh white jade piece, he carved complicated magic pattern patterns on it, raised his eyebrows, and looked a little dignified.
"Exhale-inhale-"
Li Cha took a deep breath and said to himself: "If the previous speculation is correct, then this time, it should be successful."
After saying that, Li Cha grabbed the white jade piece and injected mana into it.
"Buzz!"
The white jade piece vibrated slowly, and at the next moment there was a "crack" sound, and an orange electric arc several centimeters long was produced on the surface, which was the real effect of the magic pattern magic item "Paralyzing Ring".
Li Cha continued to input mana without reading, so that the arc continued to be born, which lasted for more than half a minute, and then "click", the white jade piece shattered.
Li Cha knew that this was caused by the energy that the white jade piece could bear reached its limit. If instead of using white jade flakes, other high-quality materials were chosen to depict the magic patterns, as long as the mana was sufficient, the duration of the arc would be almost permanent.
In other words, if the magic pattern is engraved on a blank magic item, it can be made into a qualified magic pattern spell item with paralysis effect-the magic pattern of the ring of paralysis has been successfully cracked!
Cracked successfully!
Li Cha blinked, and recorded the deciphered magic pattern on a new papyrus scroll. Compared with the original version, it was found to be simplified by almost one-half. That is to say, the magic pattern master who made the props added nearly half of the useless patterns in order to encrypt the magic pattern, which was frantic.
"Huh——"
Li Cha let out a breath, put away the new papyrus scroll, tidied up the desktop, and stretched his body.
At this moment, he is not going to crack all the three spell props he got at the auction in one go.
Thinking of this, Li Cha took out seven books—the seven books handed down from the Black Spirit Empire from the dead young man's suitcase.
He has briefly studied these seven books before, and found that only two of them are the same as the book—the last page ~IndoMTL.com~ has the logo of the Black Spirit Empire. The numbers on the sign are 11 and 34 respectively.
From this, he deduced two things.
First, not every book handed down from the Black Spirit Empire is related to secrets, and it is very likely that there are only a very few of them.
Second, even if only a very small number of books are related to secrets, the number of them will not be less than 34, or even more. And if you want to collect all, or collect most of them for research, I'm afraid it will not be easy.
Comparing these two things, what makes him find it more challenging is that until now, he has no idea what the clues related to the secret hidden in the book are—the content in the book is really simple , besides nothing irrelevant.
The situation of hiding text, he considered, is nothing more than fire, water immersion, or smearing with special reagents, etc., it is just a simple chemical reaction:
Writing with vinegar, the vinegar liquid enters the fiber, and when the paper is heated, the acetic acid accelerates the carbonization of the fiber, making the writing turn yellow and appear;
Write with blue copper sulfate pentahydrate solution. After drying, copper sulfate pentahydrate turns into colorless anhydrous copper sulfate, and the writing disappears. After soaking in water, the anhydrous copper sulfate returns to copper sulfate pentahydrate, and the writing shows;
The reaction between starch and iodine solution turns blue, phenolphthalein turns purple when it meets lye, and methyl orange turns red when it meets strong acid.
He has tried all these, and it doesn't work.
In fact, if you think about it seriously, books are hundreds of years old, and even if there are any chemical reagents, they will evaporate. If someone really wants to leave some clues, as long as they are not stupid, they will not use this method. If they are stupid, then... they don't understand this method at all.
In any case, the clues related to the secret should be hidden very secretly.
So where is it hiding?
