Chapter 281 Printed circuit board and magic pattern crack

the same night.

Laboratory, main laboratory.

Li Cha was sitting in front of the experimental table and was working hard.

Many candles were lit, releasing dim yellow light, which reflected on multiple mirrors, making a small specific area on the table extremely bright. Richard was in this area, watching the papyrus scrolls copied a few days ago. , The magic patterns of the three magic spell items that were auctioned from the auction.

Each copied magic pattern is very complicated, it looks dense and makes people dizzy. Li Cha's eyes were close, studying the direction of the magic pattern, thinking about the method to decipher the magic pattern, so as to absorb, utilize and improve.

Generally speaking, in the current world, it is difficult to crack the magic pattern, not to mention that there is a systematic cracking method.

But Richard will not limit his thinking to the present, and will connect with some relevant knowledge on the modern earth.

In Richard's view, the magic pattern of the current world is very similar to the circuit on the modern earth, and has many similarities. Even if it is not completely equivalent, 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 - circuit designers of some precision instruments will try their best to encrypt circuits to prevent plagiarism by competitors, while competitors It will work hard to get what you want.

In the development of circuits, circuits have been continuously miniaturized, and large-scale circuits have gradually become mini-circuits. The wiring between electronic parts is printed on the insulating board by printing metal wires, which becomes a printed circuit board, that is, PrintedCircuitBoard, or PCB for short.

For PCB, there are many encryption methods, generally sealing, painting, buried holes, blind holes, etc.

The cracking of the PCB re-encryption method is called copying the board, and the methods are endless and varied. In fact, in terms of technology, cracking the PCB is not a question of whether it is possible, but a question of whether it is worth it.

In other words, there is no PCB that cannot be cracked, it just depends on the investment. If the investment is too much, the gain is not worth the loss, then it is better to replace another valuable PCB to crack.

From the perspective of circuit cracking on the modern earth, looking at the magic pattern of the current wizarding world, everything becomes simpler.

Although the texture of the magic pattern is dense and cumbersome, it is still incomparable to the complex 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 also at the level of a shaker or a big brother.

Its encryption method is very basic, such as deliberately adding or hiding a certain line, or hiding the real core and functional magic lines in many wrong and meaningless magic lines.

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 to create paralyzing arcs. The magic pattern master expanded it into many useless magic lines. Most of these useless magic lines were expanded by the magic pattern master himself. of.

In this way, plagiarists have to work hard to imitate the magic pattern successfully. In this process, as long as one of the wrong lines of the core magic pattern is accidentally drawn, 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 flashing. 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, he took out the white jade piece from the space iron ring and quickly drew it according to the lines on the papyrus scroll.

"Swish..."

The white jade pieces are processed in a short time, and compared to the original magic pattern, there are many fewer lines.

When Li Cha tried to input mana, the white jade piece vibrated and shattered with a "click".

"Well... it seems that the magic patterns in the A2 and D4 areas can be ruled out.

"

After a failure, Li Cha was not discouraged, took out a new piece of white jade and painted it again, and painted a completely different magic pattern on it.

Holding the second piece of white jade, Li Cha tried to input mana into it, and then it shattered again with a "click".

"Magic patterns in areas B3 and C5 can also be excluded."

As Li Cha said, he took out the third piece of white jade and processed, painted and tested it again.

With a "click" sound, it shattered for the third time.

Then the fourth, the fifth, the sixth...

The pieces of white jade shattered one by one. When Li Cha took out the eleventh piece of white jade, he painted complicated magic lines on it, raised his eyebrows, and his eyes were a little dignified.

"breathe--"

Li Cha took a deep breath and said to himself: "If the previous speculation is correct, then this time, it should be successful."

When the words fell, Li Cha grabbed the white jade piece and injected mana into it.

"Buzz!"

The white jade piece vibrated slowly, and the next moment, with a "crack" sound, an orange-yellow electric arc several centimeters long appeared on the surface.

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 the white jade piece shattered with a "click".

Li Cha knew that this was caused by the limit of the endurance energy of the white jade piece. If you choose not to use white jade, but choose other high-quality materials to describe the magic pattern, as long as the mana is enough, the duration of the arc will be almost permanent.

In other words, if the magic pattern is engraved on a blank spell item, it can be made into a qualified magic pattern spell item with a paralyzing effect - the paralysis ring magic pattern has been successfully cracked!

Successfully cracked!

Li Cha blinked and recorded the cracked magic pattern on a new papyrus scroll. Compared with the original version, he found that it was reduced by almost half. In other words, the magic pattern maker who made the props added nearly half of the useless lines in order to encrypt the magic pattern, which was simply frantic.

"call--"

Richard let out a breath, put away the new papyrus scroll, tidy up the table top, and stretched his body.

At this time, he is not ready to take a breath and crack all the three magic items that were auctioned at the auction. It is too energy-consuming, so it is better to change his mind.

Thinking like this, Richard took out seven books—seven books handed down from the Black Spirit Empire from the suitcase of the dead young man.

He had briefly researched these seven books before, and found that only two of them, like the book, had the logo of the Black Spirit Empire on the last page. The numbers on the sign are 11 and 34.

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 only a few of them are.

Second, even if only a small number of books are related to secrets, the number will not be less than 34 or even more. And if you want to collect all, or collect most of them to study, I'm afraid it won't be easy.

Comparing these two things makes him even more challenging. Until now, he has no idea what clues are hidden in the books that are related to the secrets - the content in the books is really simple content, other than that Nothing irrelevant.

In the case of hidden text, he considered, it is nothing more than fire, water immersion, or smearing with special reagents, etc. It is just a simple chemical reaction:

When writing with vinegar, the vinegar liquid enters the fiber. When the paper is heated, the acetic acid accelerates the carbonization of the fiber, making the writing appear yellow;

Write with blue copper sulfate pentahydrate solution. After drying, copper sulfate pentahydrate turns into colorless anhydrous copper sulfate, and the writing disappears. After immersion in water, the anhydrous copper sulfate is restored to copper sulfate pentahydrate, and the handwriting is displayed;

The reaction of starch and iodine solution turns blue, phenolphthalein turns purple when it encounters lye, and methyl orange turns red when it encounters strong acid.

He has tested all of these, and it doesn't work.

In fact, think about it carefully, books have a history of hundreds of years, and even if there are any chemical reagents, they will evaporate. If someone really wanted to leave some clues, as long as they weren't stupid, they wouldn't do it this way, and if they were stupid, then...don't understand this way at all.

In any case, the clues related to the secret should be hidden very secretly.

So where is it hiding?
