Abe Nakamaru pondered: "You mean burning lime?"

"That's right, it's used to kill sterilization." Junichiro Takaki gestured.

"Go back and try it. There are burnt lime in our country, why is it called quicklime?" Abe Nakamaru is not very used to the question of symmetrical symmetry.

"Because it can also be turned into ripe lime, its uses overlap in some aspects and different in some aspects." Junichiro Takaki learned a lot of knowledge in the newspaper.

"I wonder if I can learn how to make redemption coupons and go back to print money." Abe Nakamaro knew what the redemption coupon was.

In name, it is called a exchange coupon, but it is actually currency.

His most worry is that the people are unwilling to use copper coins, and there are many small countries in China who have been enfeoffed.

In some places, copper is not produced, and copper coins are cast in Pingchengjing. People elsewhere decide that copper coins are useless.

Talking about how much it is worth is not as good as watching it yourself.

I know how many meters or cloth I can exchange for ten eggs.

What should I do if I exchanged ten eggs for a few copper coins, but I can’t buy the rice and cloth with copper coins?

The things you exchanged for are what you need, you don’t need copper, you can’t eat or wear copper.

Then I came up with a solution to allow officials to use money to get promoted.

Officials must save money themselves, and donate it to different officials according to how much.

Those who do not have officials will donate five thousand copper coins to an official.

Officials paid their salaries and paid for them with copper coins, so they could use copper coins to buy things.

However, it can only be circulated in Pingcheng Jing and Gyeonggi Province, so people outside still don’t want it.

Abe Zhongma Lu and others couldn't understand why? The people of the Tang Dynasty liked to use copper coins and also made bad money.

How bad is it to change to your own country?

With a lot of doubts, everyone continued to visit Dongshi.

Feeling the prosperity of the Tang Dynasty and envying the lives of the people of Jingzhao Prefecture of the Tang Dynasty.

There are too many things on the market, and there are so many things to say.

People pay money and find money, and even blind people buy things with redemption coupons.

There are blind spots on the exchange coupons, and they are added according to the method of creating watermarks. The blind spots for money of different face value are different.

According to the feel and size of the exchange coupon, as long as it is a little new, the blind can distinguish it.

When it comes to purchasing in detail, there is no need to distinguish blind people, and there are enthusiastic people next to you to help.

When a person who sells goods meets a blind person, he not only dares to give the bad ones, but also has to choose the good ones and give more, for fear that someone will report to the official.

"Brother, the stall owner is good. I'll give you two more coins of meat." The Japanese envoy looked at someone helping the blind man to buy things.

The extra two coins is also a weight. The ten coins are one or two liang, not the face value of copper coins.

"Hey, hehe!" The blind man carefully put the money he found, picked up the meat, and lit it with a stick to the ground and left.

A kind-hearted person immediately followed and helped the person in his thirties walk home.

The Japanese envoy was moved by the customs of Jingzhao Prefecture in the Tang Dynasty. When he saw someone selling fried cucumbers, he took out two copper coins from his sleeve.

He walked over and handed the copper coins: "Give me a roll."

The stall owner looked at the money he had taken and carefully identified it: "If you don't sell it, you won't recognize it."

"My Japanese money is the same as the Tongbao of the Tang Dynasty." The next Dao Zhenbei signaled the other party to see.

The stall owner shook his head: "No, I don't think so, I feel that it's not as heavy as Kaiyuan Tongbao."

"I'll add one qian, three qian is worth two qian. I'm a Japanese envoy." The next day, I was really depressed, and I added another copper coin.

"The Japanese envoy cannot buy things and pay less, unless you are Dongzhu Li, I will give it for free." The stall owner said and took it to his hand to weigh it a few times.

Nodded: "I sold you, no matter how you say you are all Japanese envoys."

After saying that, he put away the money and signaled the woman next to him to wrap a roll of pineapple paper for the next Taoist.

The woman carefully selected and found a large one that looked like a good weight but actually had a good weight of the noodles and handed it to the next road.

I am really in a good mood in the next road, this one looks big.

He broke off one and put it in his mouth to bite it, which was crispy.

Fujiwara Majia next to him followed and pinched one: "I really envy their money to spend anywhere."

"Li Yi is resourceful and may know what the reason can solve our domestic worries." Junichiro Takashu thought of a solution.

It is said that the prime minister would go to Lijiazhuang to ask for advice when encountering difficulties. The students born in Lijiazhuang did a good job in the county and village.

It means that if you are a master, you can ask yourself why your Japanese copper coins cannot be circulated. Can Li Yi give an idea?

...

Bi Gou was already helping Junichiro Gao Shu ask that in addition to the tribute, the Japanese envoys also had a large number of Japanese products.

Including silver, silver was used in the manufacture and opening of the same vein, but later it was cancelled because there was less silver.

The Tang Dynasty had less silver than gold, and no large mine was found.

Silver was a luxury item in the Tang Dynasty, used to make bronze mirrors and jewelry.

A little silver bronze mirror was added, which was similar to a glass mirror, but it was easy to wipe away the silver.

"Do you want to collect their taxes?" Bi Gou stood carefully at the door of a workshop and watched Li Yi operate.

Li Yi is making litmus test paper, and now it is a key step, so no one is allowed to disturb him.

After Bi Gou finished speaking, Li Yi turned his head and glared at him, and Bi Gou quickly shut up.

"I have sulfuric acid and caustic soda here, and it's over if there is any problem. Wait for me."

Li Yi continued to operate, and the red test paper added with sulfuric acid was used to measure alkali; the second type was added with caustic soda, which was used to measure acid.

People always use their experience to see the pH of the soil, so Li Yi took the time to collect litmus. After two days of processing, the finished product was produced today.

It can be used after it is done, but it needs a comparison and he has to adjust the color by himself.

In half an hour, the craftsmen who studied understood.

Li Yi breathed a sigh of relief and walked out to let the craftsmen make a lot of work. If there were not enough litmus, they would collect it.

Lits are now medicine, which is easier to find and are not worth it. Children can pick many things with a small shovel.

"With the test paper, the people have more choices when farming, and they can easily know what their land is, what needs to be added to neutralize, or which crop to plant."

Li Yi had a small bamboo piece on his hand, and two litmus test papers were placed on it.

"Character, right?" Bi Gou didn't understand the principles at all, he only knew that this knowledge was extraordinary.

"Yes, and if I don't tell you, no one will make it for hundreds of years."

Li Yi was not humble at all, so he didn't plan to teach outsiders.

He would sell test strips and comparison tables and let the court buy them.

"Do you want to give it to the people?" Bi Gou thought Li Yi gave it to him when he heard it had something to do with farming.

"The court paid for it, one hundred packs per pack, plus two comparison tables. If one is lost or broken, there will be a backup.

The government took it and sent it to the people. The people went to see their own fields, and then took the watch from the yamen to compare.

A pack of twenty coins, if you don’t need a comparison table in the future, nineteen coins, do you think it’s good?”

Li Yi had planned to sell money and farming. The court should take charge of the government.

"No, how much does this thing cost?" Bi Gou refused. He thought that buying it would suffer a loss.

"Old Bi, don't always think about the cost of materials. Don't consider the cost of technology? I've lived frugality and tried hundreds of thousands of times and invented..."
