Another world doctor

After hearing her words, Hei Ying couldn't help showing surprise on his face. He looked at Cang Yan, and Cang Yan nodded in satisfaction, "I told you, it is impossible for Luo Er not to know something."

"Huh?" Yiluo was stunned for a moment, she didn't know what Cang Yan meant, Cang Yan looked at her and said with a smile, "Before Sombra, I was afraid that you didn't know that tin ore and copper ore can be smelted, so I was worried that you wouldn't Agree to use this."

"I see." Yi Luo nodded, she looked at the shadow, "Sixty percent of this coin should be copper ore, and [-]% should be tin ore, am I right?"

Heiying couldn't help admiring Yiluo, she is an ordinary woman who knows so much, no wonder Wang said he would show her, "Yes, what Miss Yiluo said is right, I have found a few who are proficient in it. They tried a lot for forging monsters, and later found that the fusion of these two ores has enough hardness and a relatively low melting point."

"That's right, this is a bronze mine, and it's really suitable for making coins." Yiluo nodded.

"Bronze mine?" Heiying didn't know the name of this thing, he looked at Yiluo curiously, and Yiluo smiled slightly, "Well, I once knew from a hermit blacksmith that this kind of copper and tin mine The ore formed by combining them is called bronze ore." Cang Yan glanced at Yiluo and didn't say anything, of course he knew that this was something Luo'er learned from later generations.

"Luo'er, about minting coins, do you mean to use this bronze ore to cast them?" Cang Yan couldn't help asking when he saw that Yiluo was also inclined to the third option.

"No," Yiluo shook his head, "I have a question. I know that there are many copper mines not only in Departure Island, but also in Sky Continent. What about tin ore? Is it easy to mine?"

"Miss Yiluo, we have found some ore veins near the Ivy and Bamboo Realm in Liyu Island, but we haven't found any other places for the time being." The black shadow told Yiluo respectfully.

"Is the quantity enough?" Yiluo was very worried that it would be troublesome if the coins were not enough for circulation.

"Don't worry, Miss Yiluo, she has more than enough."

"Do you have Tianqiong Continent?" Yiluo asked eagerly.

"Luo'er?" Cang Yan didn't know why Yiluo asked this. Yiluo looked at him and Heiying and said, "Since we want to mint legal currency in circulation, we must ensure that these coins will not be counterfeited, otherwise someone will Making huge profits from it will affect the stability of the entire coinage system."

"This..." Soi Ying hesitated, "According to my subordinates, there are also Sky Continents, but they are simply not as many as in the Ivy and Bamboo Realm."

"Is that so..." Yi Luo looked at the bronze coin in her hand and fell into deep thought.

"Luo'er, is it wrong? If it's up to us, we'll find a way to use other materials." Seeing Yi Luo's frowning, Cang Yan could not help but comfort him.

"No," Yiluo looked at him and shook his head, "Actually, the material for making coins is not easy to find. We finally found a way to mine bronze. It would be best if we could use it. You put this coin in my mine first. Here, give me some time, I will think of a way, in short, I promise you within two days, I will definitely think of a way."

Seeing Yi Luo being so determined, Cang Yan nodded, "Okay, Luo'er, don't work too hard, you know?"

"Yeah." Yi Luo waved his hand at him, "You guys go back first, I'll look for you when I'm done."

Cang Yan took a look at Yiluo who immediately started to ponder over the desk and had to leave with Heiying first. Before he left, Heiying couldn't help but glance at Yiluo.

Yiluo locked herself in the room for an entire afternoon, until the evening when Lan Yu came to Yiluo with some food, "Girl, let's eat!"

Yiluo looked at Lan Yu who was carrying the food box, "What? Why have you changed to be a cook?"

"Oh, no, I'm a little hungry. I just saw someone delivering food to you, so I brought it for you." Lan Yu put the food box on the table and looked at Yiluo facing the paper full of things. Dazed, "What is this?"

"The newly circulated coins on Liyu Island." Yiluo didn't have much appetite, and she hadn't thought of how to prevent others from imitating them.Lan Yu nodded, "Then what are you doing now?"

"The ore needed to mint this currency is not limited to Liyu Island, but also in other places. Although we restrict the ore mining rights of Liyu Island, places such as Sky Continent may be able to mint our currency. I am afraid it will be more troublesome. "Yi Luo seems to be talking to Lan Yu, and it seems to be talking to herself.

"What about this one?" Lan Yu asked, pointing to another piece of paper.

"Oh, this," Yi Luo looked up, "I can't think of a way this afternoon, I have nothing to do to draw patterns for coins."

"Canglang? Isn't this Cang Yan's deity?" Lan Yu heard from King Liu Yue that Cang Yan's real body is the Cangyan monster clan.

"Well," Yi Luo nodded, "The Canglang clan is the king of Heixuan Palace, so I chose to use the pattern of the Canglang as the logo of the coins."

"It's so beautiful!" Lan Yu admired, "If the wolf's eyes can shine, it will be more lifelike." He just said that casually, but suddenly a thought flashed in Yiluo's mind, Lan Yu was right, if The wolf's eyes glow?

"Great! Lan Yu, thank you for having you." Yi Luo couldn't help but look at Lan Yu happily and said.

"Ah? Me? What did I do again?" Lan Yu looked at Yiluo in a daze, Yiluo suddenly had an appetite now, she stood up and came to Lan Yu's side, "Hurry up and eat, I'm hungry After finishing speaking, he picked up his rice bowl and started to eat, Lan Yu blankly looked at Yiluo who seemed to be all right from frowning at the beginning, he shook his head, "I really don't know what you are thinking. "He came to the table and sat down with Yiluo to finish dinner before leaving.

On the second day, Yiluo informed Cang Yan to let Heiying take the pattern she made to mint two coins again. Needless to say, Cang Yan couldn't help laughing when he saw the logo of Canglang on Yiluo's coin, Luo'er I really know what he's thinking.

Fortunately, Sombra's actions were also very fast. On the third day, two identical coins were minted. Yiluo asked him to send someone to bring them to him, and then told them to come back to him in the afternoon.After lunch, Cang Yan and Hei Ying came as promised.

"Luo'er." Cang Yan looked at Yiluo and smiled slightly.

"You guys are here." Yiluo pulled Cang Yan to the table, "I've already figured out a way to distinguish between real and fake coins, so that even if someone can find tin ore and copper ore, they won't be able to make the same coins as us. things come."

"Oh?" Cang Yan was very interested. He knew that Luo'er was going to surprise him again, so Yiluo took out the two coins that Hei Ying had given her from the brocade box, "Here, take a look at these two coins." What is the difference?"

Cang Yan took the two coins suspiciously. After looking at them for a long time, he found no difference. He handed them to Soi Ying, who also looked at them for a long time but found nothing.The two looked at each other, and Cang Yan said, "Luo'er, there seems to be no difference between the two."
