"And how do you want to prove it?" Sheila asked, crossing her arms.

"Show me your process for making codes." The regimental commander said, "I will judge." ”

So the girls began to whisper again.

"To sell or not to sell?"

"I think the other party is very insincere, how can you ask the other party to directly give a full set of plans if you don't pay a penny?"

"Besides, if the other party reads the plan and doesn't buy it, and goes back and messes with it according to our method, won't we lose a lot?"

"The main reason is that our method is too simple, not very technical, and easy to copy."

"Wait a minute!" Sheila suddenly had an idea, "I have an idea......

After the girls whispered and finalized, they returned to the negotiating table, smiling one by one:

"I can show you the plan."

So the head of the regiment breathed a sigh of relief and laughed: "Then please demonstrate." ”

Mia brought materials out of the church: small notes, potato stamps, carbon paper...... as well as matches and wax.

"Our approach is simple." "With your eyes closed, you print the pattern on the potato stamp on paper, and use carbon paper to create multiple strips of paper with the same pattern. ”

"Because the maker closes his eyes the whole time, the anomaly cannot see the arrangement and rotation angle of the seal pattern on the paper through the maker's memory."

"However, the pattern on all the slips of paper is the same, and each person carries a small note to check the slip when they are identified."

"If it's true, then the patterns on the strips of paper should be consistent with each other. If the other party is a duplicate, then there will be a problem with the pattern on the strip of paper. ”

"After each confirmation, the code is invalid, so it is recommended that you buy multiple sets of passwords. When one set runs out, you can use the next set. ”

"Hmm......" the head of the regiment thought as he touched his chin. This method, although simple, is also a bit ingenious, and the key is that it can be easily replicated.

For example, potato stamps can be replaced with clay clods; Small strips of paper can be replaced with strips of cloth; Carbon paper is the most troublesome, but the maker arranges all the strips of cloth in advance, closes his eyes and stamps each strip of paper, as long as the hand is steady and does not rotate, the pattern of the cover is similar.

So we can do it ourselves, so there's no need to buy them...... Just as the head of the regiment began to have a dark belly, Sheila on the opposite side suddenly smiled and said:

"Of course, this method is not perfect, and there is still a fatal flaw."

"Vulnerability?" The regimental commander wondered.

"Yes." Sheila laughed, "Until you get the code, I'll assume that your team doesn't have a way to identify clones. ”

Isn't this nonsense, if there is a way to identify it, I still need to ask you to buy a password? The regimental commander thought to himself.

"So." Sheila's gaze circled the mercenary behind him a few times, "Suppose your team is now mixed with clones......"

“…… Then after he gets the code paper in his hand, he only needs to secretly open it and take a look, and your code will be invalid. ”

Head:..................

it!

"Since you say that, there must be a solution, right?" The head of the regiment showed a skeptical expression.

"That's right." Sheila took the matches and wax blocks next to her, "I wonder if you've ever heard of the Oriental Wax Pill Book?" ”

"Light a match, heat the wax block, and put the kneaded paper ball in. When the wax block solidifies into a wax pill, the book is perfectly sealed inside. ”

"If you want to see the note inside, you have to cut open the wax pill with a weapon, which of course will undoubtedly destroy the wax pill."

"So, put all the codes in the wax pills, and then have the mercenaries carry the wax pills in a prominent place, such as stringing them around their necks. In this way, once you see that the wax pill in someone's neck is destroyed, then the set of codes will be invalidated by default, preventing the code inside from being leaked to the mutation, and you don't know it yet. ”

"Hmm." The regimental commander thought that this method was starting to get complicated, and after thinking for a long time, he asked, "But what if you encounter a fierce battle and don't have time to take care of everyone?" ”

"If there is a clone in my team, then when the battle is at its most fierce and everyone can't pay attention to him, it quickly takes off the wax pill and dissects it, and then the mutation quickly makes another clone and mixes in with the intact wax pill......"

"That is, your skills are not as good as others, so you have given the abnormal change an opportunity to take advantage of." Sheila said unceremoniously, "To put it bluntly, if the strength is really too poor, even if you are given the code, then your members will be captured and killed by monsters, and then the code will be opened to take a look, wouldn't it be useless to use any encryption measures?" ”

"We can give you the code. Designed in the form of a wax pill, it is also designed to increase the time it takes to read the code, so as to increase the difficulty of mutant spying on the code. However, if you're so weak on the battlefield that you're going to take some of your members out of sight for a few minutes, it only means that you're not fit to deal with this mutation, so get out of the town as soon as possible. ”

Head:..................

For some reason, being insulted in a contemptuous tone by this masked girl, he felt an inexplicable sense of comfort.

It's as if something strange has awakened.

If you think about it, what the other party said is not wrong. It is estimated that there is no foolproof code scheme, but as long as this code scheme is perfect enough to increase the probability of identifying replicas to an acceptable level, it will be okay if it is not 100% effective, and it still has enough commercial value......

What is the business value?

"We can buy this code." The head of the regiment said with a smile on his face, "However, I wonder if you are interested in cooperating?" ”

"Cooperation?" Sheila was puzzled.

"You provide the materials, we will do the work." The group leader rubbed his hands together with a smile, "Sell this set of codes you designed to the major mercenary teams in the town that have been extremely miserable by the clones." ”

The girls were shocked.

Wow, we didn't expect that we could still get rich by selling this for money? You're a bit of a business-minded guy! How did you come to be a mercenary? Qu Cai, right?

"Actually, our iron ship mercenary group will also engage in some smuggling part-time in our spare time." In the stunned eyes of the girls, the head of the regiment explained with a smile, "We are still a little confident in negotiating and finding a way. ”

"Think about it. You are the ones who invented this method, but you don't have enough people to sell these resources. We can provide manpower and channels, but we need your side to provide raw materials, so it is a win-win situation for us to work together. The head of the regiment said, "I just don't know your supply capacity......

"The supply capacity is no problem." Sheila said. Other mercenary groups will not carry some messy things on their bodies because of the weight problem.

However, after all, the girls have a team on the island of fire, not to mention wax blocks and matches, toothbrushes, toothpaste, towels, toilet paper, napkins, ceramic bowls, all kinds of daily necessities, and even a lot of them are on the island.

"That's good. In this way, you will be mass-producing ciphers in the church, and we will come and pick them up regularly, and then sell them to other mercenary groups......"

"Wait." Sheila corrected him, "You can't sell the code directly, because the major mercenary groups can't confirm whether you are a mutant copy or not, so they won't trust the code in your hand." ”

"Yes, yes, yes." The leader of this iron ship mercenary group also reacted immediately, "Then we should ......"

"You buy materials from us!" Sheila said, "Then take the materials to find other mercenary groups, explain on the spot, make on the spot, and sell on the spot!" ”

"That's right!" The head of the regiment slapped his thigh and agreed with Sheila's statement, and then suddenly realized another problem.

If they buy the code directly and then sell it, then they will pay according to the actual number of the code sold. As for how much to sell, isn't that the iron ship mercenary group that controls the channel have the final say? I bought 100 copies of the materials and sold 90 copies, but I insisted that only 40 copies were sold, and I had to settle the bill according to 40 copies, and the girls had no way to confirm it.

However, if you buy materials directly, you will pay the money with one hand and deliver the goods with the other, and the price will be as much as you negotiate, and there is no room for the Iron Ship Mercenary Group to cheat and falsify sales......

Did you think of such a deep detail before you even talked about the business model?!

The leader of the Iron Boat Mercenary Regiment stared at the masked girl opposite him in astonishment, completely unable to see the expression of the other party's mask.
