Although the detachment led by Jiang Lu failed to complete the feat of circumnavigating the island, it brought a gift to the other members of the fleet, that is, more than a dozen lobsters weighing hundreds of pounds. Originally, they caught a lot of these big lobsters, but unfortunately in just a few days, most of them died, and in the end only these dozen survived, and Lu Wan also knew that this thing could not be raised, so in the end it was decided to transport them all to the kitchen and feed all the crew.

Although the lobster was eaten, but the dragon shell was left by Lu Wan, and it was cleaned and spliced together according to the original appearance, in addition, he also let people catch some strange animals on the big island, such as the big island called the gray crane, and there is also a very large, like a mouse, and there is a strange bag on the stomach of the animal, etc., each animal try to bring as much as possible, this is to be sent to Taiwan, I heard that His Royal Highness King Qi wants to set up a zoo and exhibition hall, and now he is ordering people to collect animals everywhere, Presumably, the ones they brought with them would be very popular.

In addition, Lu Wan also found an interesting phenomenon, that is, among the animals on the big island, there are many animals with bags on their stomachs, such as the mouse-like animal they caught, and there is also a kind of bear that lives in the trees also has bags, and even the wolves that hunt around also have bags, these strange animals are eye-opening, so they have sent people to catch some and bring them on the boat, and there are also some plant seeds, and they also collect some as much as possible.

After a few days of preparation, Lüvain's fleet was finally ready to set sail, but they had already built a simple dock on Sunset Island, and Tomori took care of it. For this matter. The headman, Rumodo, naturally agreed, after all, he also expected these wealthy outsiders to come to their island again to trade with them.

When Luvan they left. All the members of the Morri's department came to the port to see them off, and Rumodo was wrapped in half a horse of silk. He kept waving goodbye to the fleet, and the glass bracelet in his hand glittered with his movements. However, among the crowd, the saddest one was Duoya, she and Luvan went to the big island to find gold, and formed a strong friendship with everyone, and Luwan They also liked Duoya very much, and when they left, many crew members gave Duoya some small things, although they didn't think it was too valuable. But for Doya, it is an extremely precious gift.

In fact, not only did Duoya get the gifts from the crew, but almost the entire Morli Department accepted the benefits of the fleet, and even Lu Wan made an exception to give Moli some bows and arrows and taught them how to use them. This move greatly increased the hunting ability of the Moritry, and it was able to hit more prey than before, making the Moritra people less likely to starve.

It was precisely the above actions that caused Lu Wan and the others to leave, and the entire Mo Li Department came to see them off. After all, in their eyes, these outsiders who came on a big ship were a kind people, and they were very generous, like messengers sent by the gods.

However, the reason why Lu Wan and the others are so enveloped by Mo Libu. But they didn't have any good intentions, and everything still originated from the gold mines they found on the big island. Although they had only been there for a few days, the crew had already found a lot of gold nuggets and golden sand. Therefore, Lu Wan and Feng Shijie have reason to believe that there should be a large gold mine there. There is definitely value in mining.

A gold mine with mining value, the slave trapping association behind Lu Wan will definitely not let it go. After all, the association is not only a slave hunting business, there are also many other related industries, as for gold mining, which is almost equivalent to money grabbing, it will naturally not let go.

However, if you want to mine gold on the big island, then you must send some people to be stationed on the big island, and this requires the help of the Mo Li department, after all, they are the natives here, no one is more familiar with the situation on the island than them, and with their help, I believe that the people who come should be able to gain a foothold on the big island soon.

Compared with the road they came, Lu Wan did not seem easy when they returned to the sea, after all, the sea is changing, and no one knows what they will encounter in the next moment? Therefore, Lu Wan's return voyage was also full of dangers, and they also had to overcome difficulties in food, water, and fear, and sailed all the way to the place where they set sail.

Just when Lu Wan and their fleet returned with a great discovery, Li Su in Dengzhou City also received a message from Yanbei, originally the exploration fleet was just set off to find a new source of slaves, which was not a big deal in Yanbei's opinion, so he didn't report to Li Su, but when the two exchanged letters later, he mentioned it in passing, which made Li Su very surprised, and regretted that he couldn't explain to each other before the fleet set off, although he didn't dare to guarantee that the other party would definitely be able to reach Australia. But according to the direction of the voyage that Yanbei said, it is indeed very likely to reach Australia.

However, although Li Su is concerned about the exploration of the fleet, he is now entangled in another matter, and he does not have too much energy to take special care of it for the time being, so he has to explain to Yanbei, if the people from the fleet come back, he must tell him in advance, and he must personally greet him and ask the other party some questions.

"Yifan, you should have no problem with the machine here, although 200,000 silver coins have been produced now, but in a month, I will see 200,000 again, and this is only the first issue of silver coins, and there will definitely be more silver coins issued in the future, so the machine here will continue to work for a long time without stopping, if there is any problem, then it will be a big trouble!" Li Su said loudly to Yifan beside him.

They were now in a noisy factory, surrounded by the roar of steam engines, and under the drive of steam engines, machines were working at a rapid pace, and at the same time emitting a very regular 'clang' sound. In this environment, if people don't speak loudly, they can't hear what the other person is saying at all.

"Your Highness, rest assured, as long as you can provide enough silver and copper, there will be no problem in producing 200,000 silver coins a month!" Dressed in a cyan robe, Yi Fan, dressed as a man, said with a smile.

Hearing Yifan's words, Li Su nodded reassuringly, Yifan is the person he trusts the most, and as long as the other party agrees, he must be sure that it will be done, so there is no need to doubt it at all.

Li Su and his family were located in the newly established mint, which was not set up by Li Su on the island of Taiwan, but was still built in Dengzhou. Although Li Su has been transferring some of Dengzhou's industries to the island of Taiwan, the currency reform is mainly in Datang, so it is better to set up in Datang, at least the transportation cost is much lower.

When he was attacking the Wa Kingdom, Li Su told Cheng Huailiang that he wanted to add a higher value coin to the Tang Dynasty copper coin, and this kind of coin was a silver coin. Although Li Su also wants to do it in one step and exchange the current metal currency for the paper money of the future, the reality tells him that this is not something that can be done in a short period of time, at least for most people, they cannot fully accept paper money.

Although Li Su's bank has been opened all over the major cities of the Tang Dynasty, many people like to deposit money in the bank, and there are bankbooks under the cabinet at home, but the passbook is still only regarded as a kind of proof of saving money, and it cannot be circulated at all, although there are some nimble businessmen who open some bearer passbooks for some commercial transactions, and anyone with this kind of passbook can withdraw money. But this is a minority, and it is only used for commercial circulation, and very few people use it, so it is not paper money at all.

The news from the bank made Li Su understand that in a short period of time, metal currency is still the protagonist in the market, even if he forcibly launches paper money, I am afraid it will not be recognized by the people and become waste paper, and the best result is only to make paper money in a subordinate position, and it cannot exist independently from metal currency.

It is precisely knowing the above that Li Su decided to come step by step, first issue a relatively large face value of silver coins, after all, now after the development of commerce, the amount of commercial transactions is getting larger and larger, and a general business will also use dozens or hundreds of runs, if it is settled with copper coins, it will be too troublesome, so it is imperative to issue silver coins with large face value.

However, it is a pity that the Tang Dynasty did not realize this, the old household management system has become more and more unable to keep up with the speed of commercial development, and coins are one of the very prominent problems, and Li Su decided not to trouble Li Shimin anymore after knowing this problem, because he already has the ability to solve this problem.

In order to find the silver needed to issue silver coins, Li Su hit the idea to the head of the Wa State, mobilized the upstarts of Chang'an, and laid down the Iwami Silver Mine of the Wa State together, and then organized the Wa people to mine on the spot, after nearly half a year of development, now the Iwami Silver Mine has formed a certain scale, and it can produce quite amazing silver every month, plus the silver reserves that Li Su let people collect before, it is enough for him to issue silver coins.

As for Yifan here, Li Su also gave instructions in advance, and asked her to help design a stamping machine driven by a steam engine, the structure of this machine is relatively simple, the previous steam engine manufacturing factory also had a similar machine, and now it can be used as long as it is modified, and there is also the style of silver coins, Li Su decided to use the traditional round square hole, and even the words on it have not changed, it is still the four characters of 'Kaiyuan Tongbao', which is also the main currency during the reign of the Tang Dynasty.

The reason why the form of a circular square hole is used, firstly, it can be threaded in the middle, which is more convenient to carry, and secondly, this kind of graphic also represents a cultural tradition, so there is no need to become a kind of perfect circle that is later formed. In addition, there is a very important reason, that is, with the style of Kaiyuan Tongbao, then the molds for coinage are ready-made, and there are many craftsmen who can make this kind of molds, and they can be used to modify it.

However, Li Su is not a living Lei Feng, the reason why he implemented the currency reform of the Tang Dynasty by himself is also to save his own selfishness, but his selfishness is hidden very deeply, except for himself, I am afraid that no one else knows. (To be continued.) )
