Same night.

Laboratory, main laboratory.

Richard sat at the lab table, working earnestly.

Many candles were lit, releasing a dim yellow light, and the reflection of multiple mirrors made a small area on the table, extremely bright, and Richard was in this area, looking at the magic patterns of the three magic spell items that had been copied from the papyrus scroll the other day and obtained from the auction.

Each transcribed magic pattern is very complex, and it looks dense, making people's eyes dizzy. Richard's eyes were thin, studying the direction of the magic pattern, thinking about ways to crack the magic pattern, so that he could absorb, use, and improve.

Generally speaking, in the current world, magic patterns are very difficult to crack, let alone have a systematic way to crack them.

But Richard doesn't limit his thinking to the present, he connects with some relevant knowledge on the modern earth.

In Richard's view, the magic patterns of the current world are very similar to the circuits on the modern earth, and have many similarities. Even if it is not exactly the same, you can use some of the knowledge on the circuit.

On the modern earth, the development of circuits has always been accompanied by encryption and cracking, just like spears and shields - some circuit designers of precision instruments will try their best to encrypt circuits to prevent them from being plagiarized 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 slowly becoming miniature circuits. The wiring between electronic parts is printed on an insulating board by printing metal wires, and becomes a printed circuit board, or PCB.

For PCB, there are many encryption methods, such as sealing, painting, buried vias, blind vias, etc.

For the cracking of PCB heavy encryption methods, it is called copying boards, and the means are endless and diverse. In fact, as far as technology is concerned, cracking the PCB is not a question of whether it is worth it at all, but whether it is worth it.

In other words, there is no PCB that cannot be cracked, it just depends on how much is invested. If the investment is too much and the gains outweigh the losses, then it is better to change to another valuable PCB to crack.

And from the perspective of circuit cracking on the modern earth, everything becomes simpler in the current wizarding world.

Although the texture of the magic pattern is dense and cumbersome, it is not comparable to the complex PCB on 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 rocker or a big brother.

The encryption method is very rudimentary, such as deliberately adding or hiding a certain line, or hiding the real core and functional magic patterns in many false and meaningless magic patterns.

This is enough to deal with ordinary plagiarism, and 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 created a paralyzing arc, and the magic pattern master expanded it into many useless magic patterns, and a large part of these useless magic patterns were impossible for the magic pattern master himself to repeat.

In this way, it takes a lot of effort for the plagiarist to imitate the magic pattern successfully. And in this process, as long as you accidentally carve the wrong line of the core magic pattern, the entire magic pattern will fail, enough to collapse.

However, the same encryption method is not enough for Richard.

Under the light, Richard looked at the lines on the scroll, his eyes flickering. Fingers were put up, slowly sliding, dividing the area, calculating the combination of some magic patterns, and quickly thinking of the specific method of testing.

The next moment, he took out the white jade piece from the spatial iron ring and quickly carved it according to the lines on the papyrus scroll.

"Rustling ......"

The white jade piece was processed in a short time, and there were many fewer lines than the original magic pattern.

Richard tentatively input mana, and the white jade piece vibrated and shattered with a "click".

"Hmm...... It seems that the magic pattern in the A2 and D4 areas can be excluded. ”

After a failure, Richard was not discouraged, and took out a new white jade piece and carved it again, carving a completely different magic pattern on it than before.

Holding the second white jade piece, Richard tentatively injected mana into it, and then shattered it again with a "click".

"The magic pattern in the B3 and C5 areas can also be excluded. “

Richard said, taking out the third white jade piece, processing, carving, and testing it again.

"Click", the third time to break.

Then there was the fourth, the fifth, the sixth......

The white jade pieces were broken one after another, and when Richard took out the eleventh white jade piece, he carved cumbersome magic patterns on it, his eyebrows were raised, and his eyes were a little solemn.

"Breathe—breathe—"

Richard took a deep breath and said to himself, "If the previous speculation was not wrong, then this time, it should have succeeded." ”

As the words fell, Richard grabbed the white jade piece and injected mana into it.

"Buzz!"

The white jade piece vibrated slowly, and the next moment there was a "crackle" sound, and an orange arc several centimeters long was born on the surface, which was the true effect of the magic spell prop "Paralysis Ring".

Richard's continuous unread input mana caused the arc to continue to grow, which lasted for more than half a minute, and then with a "click", the white jade piece shattered.

Richard knew that this was due to the fact that the energy of the white jade piece had reached its limit. If you don't choose to use white jade tablets, you choose the rest of the high-quality materials to depict the magic pattern, as long as the mana is sufficient, then the duration of the arc will be almost permanent.

In other words, if you depict the magic pattern on a blank spell item, you can make a qualified magic pattern spell item with a paralyzing effect - the paralyzing ring magic pattern has been successfully cracked!

Crack it successfully!

Richard blinked, and recorded the cracked pattern on a new papyrus scroll, which was almost half thinner than the original version. In other words, the magic pattern master who made the props added almost half of the useless lines in order to encrypt the magic pattern, which was simply frustrating.

"Whew-"

Richard let out a sigh of relief, put away the new papyrus scroll, straightened the table, and stretched.

At this time, he was not ready to crack all the three spell props auctioned at the auction in one go, it was too energy-consuming, so it was better to change his brain.

With this in mind, Richard took out seven books—seven books from the Black Spirit Empire that had been handed down from the dead young man's suitcase.

Of these seven books, he had briefly studied them before, and found that only two of them, like the book "My Autobiography - Moratos", had the logo of the Black Spirit Empire on the last page. The numbers on the logo, 11 and 34, respectively.

From this, he deduced two things.

First, not every book that has been handed down from the Black Spirit Empire is related to secrets, and it is likely that only a very small part of them are related.

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 it all, or collect most of it to study, I'm afraid it won't be easy.

What made the comparison even more challenging for him was that, until now, he had no idea what the clues were hidden in the books that were related to the secrets - the contents of the books were really simple contents, and there was nothing unrelated about them.

In the case of hiding words, he considered that it was nothing more than fire, water immersion, or smearing with special reagents, etc., it was just a simple chemical reaction:

When writing with vinegar, the vinegar liquid enters the fiber, and when the paper is heated, the acetic acid accelerates the carbonization of the fiber, so that the handwriting turns yellow and appears;

Writing in blue copper sulfate pentahydrate solution, after drying, copper sulfate pentahydrate turns into colorless copper sulfate anhydrous, and the handwriting disappears. After immersion, anhydrous copper sulfate reverts to copper sulfate pentahydrate, and the handwriting shows;

The starch and iodine solution react to turn blue, phenolphthalein turns purple-red when it encounters lye, and methyl orange turns red when it encounters strong acid.

He has tested all of these, but it has not worked.

In fact, if you think about it seriously, books are hundreds of years old, and even if there are chemical reagents, they have volatilized. If someone really wants to leave some clues, they won't use it this way as long as they aren't stupid, and if they're stupid, then it's ...... I don't understand this way at all.

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

So where exactly is it hidden?
