Another world doctor

"Oh?" Yi Luo slightly raised her eyebrows and smiled, "Can't even you see it?" She pouted at Cang Yan, "Here, try to cover the coin with your hand and see the difference. "

Cang Yan immediately followed suit, and when he saw the two hidden coins in his hand, he couldn't help showing joy, and he immediately understood Yiluo's intention, and Hei Ying couldn't help being shocked when he saw the coins in the same way, "This ...Miss Yiluo, how did you do it? Why does one of the coin's wolf eyes glow green?"

Yi Luo smiled slightly, "This, thanks to Lan Yu reminding me yesterday."

"Him?" Cang Yan curled his lips, is that guy still useful?

"Don't tell me, sometimes he is really useful. Yesterday, Lan Yu told me that it would be great if the wolf's eyes would glow. I suddenly thought of a way. I saw some Herbal medicine can have a glowing effect when configured in a specific way, so I smeared some on the eyes of the gray wolf on this coin. I will give you this formula at that time, but you must find a trustworthy person to supervise the coinage. People have to supervise the smearing during the minting process, otherwise the consequences will be more troublesome. Also, the minted coins of the outlying island also need to have a name, since there is a wolf pattern on the back, it might as well be called Cang coins." Yiluo told Cang Word.

"Okay, don't worry, I will leave this matter to Heiying to handle it myself." Cang Yan embraced Yiluo, "Luo'er, you are really too smart."

"Also, there are different denominations of these Cang coins. When you make them, you will make them according to the quantity I give you. You don't need to make so many large denominations, and you must not have less small denominations that need to be circulated." Yiluo added Instructing Sombra, Sombra nodded seriously.

Yi Luo smiled and broke away from Cang Yan's arms and returned to the table again, "It's not over yet, I still have something to show you." After speaking, she took out two pieces of paper and handed them to the two.

"This is?" Cang Yan raised the paper in his hand, not knowing what it would do.

"Do you still remember the ticket number I told you?" Yiluo looked at Cang Yan with a smile, "I have seen a similar ticket from Ye Hongfei before, as long as this kind of ticket is presented at the corresponding ticket number, it will be fine. Withdraw the corresponding value of money, but I have found that some people will forge seals and bills, and this kind of loss is considered a very large cost for Ye Hongfei's ticket number."

"Then this..." Soi Ying couldn't help interjecting.

"This can effectively avoid forgery of the ticket number." After finishing speaking, Yi Luo handed the two of them a pen, "Here, try to fill in [-] Cang coins in the value here."

The two looked at each other suspiciously, and each took a pen to write it down. They said while writing, "When the bank accepts the Cang coins deposited by the customer, you can get a ticket like this. All the tickets There will be a corresponding number, this is for us to have a record."

"Then how can this avoid forgery?" Cang Yan put down the pen and looked at Yiluo, at this time Soi Ying had finished writing.

"Don't worry," Yi Luo waved his hands, "Suppose you just gave a certain ticket number [-] coins, and the ticket number will issue you such a receipt. This is the time when you need your fingerprints and the stamp of the ticket number." Luo Yi raised his hand and handed the two of them an ink pad, and the two pressed their handprints respectively.

"Okay, you have set up the fingerprints, and the ticket number will be stamped at this time." Yiluo said, picking up a random bumpy object and pressing it next to the fingerprints of the two, "here, this way alright."

"This..." Cang Yan didn't understand, could this really solve the problem Luo'er said?

"Now suppose you have bad intentions and want to change the ten thousand Cang coins into one hundred thousand, what will you do?" Yi Luo looked at the two with a smile.

"Add a stroke to a word." Soi Ying thought for a while, Yi Luo nodded, "Okay, try it." Hei Ying glanced at Cang Yan, Cang Yan nodded. Prepare to add a sum to the bill.

But just after he finished adding, a strange thing happened. Originally, the note was written with a black pen, but although the pen he added was written with the same pen, that pen was clearly vermilion, and vermilion It became thicker and thicker, and finally he watched the paper turn vermilion.

"This...how is it possible?" Hei Ying stammered a little, and he looked at Yi Luo with a puzzled expression.

"How about it? If that's the case, you believe that no one can tamper with it?" Yi Luo nodded to Cang Yan, "Try this, and put it behind the extracted column." After speaking, hand it to him Another randomly found thing that can be temporarily used as a seal, Cang Yan suspiciously took another inkpad designated by Yiluo in that column, and saw that the inkpad just touched the bill, and the whole bill began to change color. It's not like the vermilion that was tampered with just now, but it has become a kind of light green, thinly covering the bill.

"How about it, the problem of tampering is solved. When you extract it, stamp the designated ink pad to identify the authenticity, so you don't have to worry about it, right? If anyone wants to make a transaction, they can come to our designated ticket number to witness each other If you issue a bill, then it is equivalent to having multiple guarantees." Yi Luo stretched her waist.

"Lu'er, how did you do it?"

"It's very simple. Add some unique materials to the paper used to make the bill. Only the designated ink pad can be used to effectively verify the authenticity. If someone tampers with the bill, the entire paper will be invalidated. That's it." Yi Luochong laughed. laugh.

"Miss Yiluo, you are too powerful." Heiying couldn't help but admire.

"Okay, that's all I can help. The rest depends on Cang Yan's influence. I only write the formula to you, and you are responsible for Sombra. If there are any problems in the process, then the responsibility Who knows it very well?" Yiluo glanced at Heiying, and Heiying immediately clasped his fists together, "Wang, Miss Yiluo, don't worry, Heiying will swear to the death to be loyal to the King of Pangsheng, and he will never betray Pangsheng. Tao things."

"I believe you, but even if you do it, I believe you should know that I must have a plan, so..." Yiluo paused, and Heiying immediately nodded and said seriously, "Miss Yiluo, please don't worry. , Sombra is not that kind of person."

"Okay." Yi Luo nodded, "Then it's up to you."

"Luo'er, don't worry, I will definitely arrange this matter properly." Cang Yan and Yi Luo looked at each other, Cang Yan's eyes were filled with gentle smiles.

Sure enough, about seven or eight days later, Cang Yan told Yiluo that everything was ready, and he had already sent Black Shadow to the four major realms to prepare first, and Yiluo also discussed with Cang Yan, and she planned to wait half a month. Let's go to Haiming Youjie first. Although Cang Yan is extremely reluctant, he has no choice but to agree. Fortunately, he plans to let King Liuyue also go to select some people who will join the Royal Guard and Blue Wind Pavilion. He can go with Yiluo by the way. Protection Yiluo.
