Wu Qian was a little clear about what Li Guan said, but he didn't quite understand it.

"Yanei's job was suddenly enlightened, but our Daheishan Island has many snakes and flints, and there are no other specialties."

Li Guan shook his head and sighed: "Add value, what we need to do is what others don't have. Or use what others already have to process and add special value, so that people can have no one and only make money. Today I will show you a clear road to Daheishan Island. If you have flint, you can organize a mining plant and mine first. Then, then process flint into special commodities."

"What kind of goods can flint be used for?" Not only did Wu Qian not understand very well, but also officers from Daheishan Fort such as Lin Wei and Zhang Chengzong did not understand very well.

Li Guan took out his body, took out a shining thing, showed it in front of everyone, then turned on the object with only a few thumbs, rubbed it a few times, and a spark sputtered, and a flame burned in front of everyone.

Looking at the orange-red flame swaying, everyone was amazed that they had never seen such auspicious tools. Fire slicing, fire coal, or even fire knife, were not so convenient and fast.

"What is this?" Wu Qian swallowed. He felt that this thing seemed to be the business that Li Guan wanted to hand over to them, but he couldn't believe it.

"This price was made by me just found a craftsman. It seems magical, but it is actually just an iron shell outside. Of course, you can also turn the shell into steel, jade, or even gold, silver, and copper. There are actually two things that are critical. One is the one I rubbed just now. The other is the one that everyone is familiar with, flint. The other is a small oil bottle inside. The oil bottle is soaked with kerosene and a small fire core with cotton from the Western Regions. It is done."

The lighter is also a new product that Li Guan thought of considering the flint resources on Daheishan Island. There are two key things that lighters need, flint and kerosene. There are also many flint on Daheishan Island, and even Plow Rake Island and Mantis Island. Kerosene. When making magical fire, distillate gasoline is required, and kerosene can be made together easily. It is even possible to simply use gasoline directly. If you want to save trouble, even vegetable oil can be used.

Compared to the fire break, the lighter is a completely huge leap. Li Guan believes that if you make this thing, you will definitely not worry about the lack of a market.

After carefully introducing the production process of the lighter, Wu Qian and others had their eyes blushed and their faces were red with excitement. Such a daughter-in-law product is not inferior to that of white wine.

Seeing their excitement, Li Guan said in the back: "This lighter workshop can be made by Daheishan Fort, but it is stated in advance. This workshop belongs to the town general's mansion and is managed by Daheishan Fort. The workshop workers use the people of the hoarding fort. Just like this product, you can build a flint mining team on each of the three islands of Heishan Island, Mantis Island and Plum Island. You can also build a chassis blacksmith team, and even this assembly can be used in the end to recruit women of the hoarding fort. In short, this product requires a lot of people, which can solve the labor force of the people and give everyone the opportunity to make money."

With a lighter, Li Guan can also sell lighter oil directly, which can make another profit.

Of course, it is impossible for tens of thousands of people on the island to get lighters, and so many people cannot be used. For the rest, Li Guan simply took out some of the ideas he had come up with during this period.

They are all on the island, and their biggest resource can be said to be fish in the sea. However, fish is not easy to preserve. Apart from eating it now, they can only be dried into dried fish or smoked fish. There is no other way.

People who often travel on the boat at sea are sick because they cannot eat fresh vegetables, fruits and other foods, and some suffer from serious life-threatening scurvy. This is a helpless thing for the crew members. Li Guan discovered that the crew members of the Dengzhou in the Tang Dynasty did not have much solution to this. Generally, they are essential beans and soaked bean sprouts on the boat. This is a rare vegetable that can be used on the boat. In addition, they are just bringing some grapefruits or some other seasonal fruits, but it is also difficult to preserve for a long time.

Considering that our Sage Army now has two fleets, often floating on the sea. Other soldiers have recently begun to suppress bandit training everywhere, and they often stay outside. Many soldiers have reported that logistics is inconvenient to carry food, so they can only bring some dry steamed buns or pancakes. It is fine when it is cold, but it is hard and unpalatable. It is hot but easy to break. Everyone is marching outside, and there is no time, and sometimes they can't even have a decent meal.

When he thought that the monk army might conduct marching and fighting in a longer range in the future, this problem could not help but bother Li Yan. After thinking for a long time, he finally thought of canned food. Canned food was a good way to store physical goods for a long time that the Napoleonic government used a huge bonus of 12,000 francs in later generations.

In fact, it is simple and difficult to say. The method of canning is to process the food, then put it in a wide-mouthed bottle, place it in a boiling water pot, heat it for 30 to 60 minutes, plug it tightly with a cork while it is hot, then reinforce it with a thread or seal it with wax. This method can preserve the food for a long time without rotting or deteriorating. However, it is also OK to use a sealed pot or porcelain bottle, or even a gourd or bamboo tube to make containers.

In fact, the method of storing food in my country was used in the folk as early as three thousand years ago. The earliest agricultural book "Qimin Yaoshu" has the following record: "First cut the livestock meat into pieces, add salt and wheat flour and mix well, and then mix it, and seal the head of the porcelain with dense mud in the inner porcelain." Although this is somewhat different from canned food, it is also similar.

"This is really feasible?" Lin Wei was a little skeptical. If this method is really feasible and can last for one or even one or two years, then this would be very useful. "Will all the fish we caught be treated like this and canned?"

"Of course, not only can fish can be canned, but also pork, beef, mutton, even chicken, duck, geese, and even wild animals. Even our vegetables and fruits can be canned in this way. With these cans, our fleet crew can eat vegetables on the ship. When soldiers march and fight, they don't have to worry about making fires and cooking, and they have ready-made canned food. Not only is it easy to transport, but it is also easy to store and delicious."

Wang Chong, the new town general of the Lushan Fort who was accompanying, hurriedly shouted: "This project is handed over to our Fort for work. They all have lighters. It is impossible that our Lushan Fort is raised by our stepmother."

Seeing Wang Chong's anxious look, Li Guan smiled and said, "Don't be anxious either. This can consume food and is not too easy to make. I bet that even if we make this product together in Shamen Town, there will definitely be a market. Think about it, if there are fresh canned vegetables and fruits, all the merchant ships in Dengzhou have to buy a batch. We can make more varieties of other canned foods, and some people are willing to buy them."

Hearing that Li Yan had such a good prospect, Wang Chongcai grinned and smiled aside. The current situation of the Lunshan Fort is similar to that of Daheishan Fort. So many people have been moved to the island at once. There is not enough field on the island, and he is worried about not knowing how to support so many people. Now this canned product has already made him very satisfied. In particular, Li Yan promised him that as long as the canned food in the Lunshan Fort is of good quality, Shamen Zhenjun will order the cans they produced.

According to the situation under Li Guan, Wang Xianzhi was about to revolt. According to the development of this situation, the Shamen Town Army, which has been registered in front of the commander Song Wei and the military commander Yu Wanrong, may be transferred to Qingzhou at any time, and the Xinye uprising army in Qizhou. When sending troops outside, it will be difficult to ensure the logistics. Li Guan didn't believe that there would be good logistics for each place to supply them. It would be better to get more cans and prepare them. Then, he would just use a pack horse to pull the cans to the front line, so that he could have enough food and clothing.

"Organize more remaining young and strong fishing in the sea. Pigs, sheep and cattle are hard-won, but there are all kinds of fish in the sea. Everyone can catch them and process them and make them into canned food. In any case, fish are also meat dishes, which are more than ten times better than wild vegetables and big cakes on the battlefield." Li Yan said with a smile.

Wang Chong and Wu Qian and Lin Wei all rushed to say that they would organize a fishing team soon and catch as much as they can. In the past, they could not finish selling and could not eat them, but now they don’t have to worry about bad things, so they really caught as much as they can.

"In addition to making lighters and canned food, we can also dry salt." Li Guan simply told the generals around him about the salt field salt drying method in later generations. Nowadays, salt is extremely expensive because of the imperial court's monopoly method, and a bucket of salt costs more than a hundred yuan. This salt almost always catches the price of rice, and even food such as sorghum and millet are almost no different. People living by the sea can't afford salt, which is really an inhumane practice.

There are more than 100,000 people in Shamen Town now, and Li Guan doesn’t plan to spend the money to buy salt at a price of rice.

"This salt field does not require many people, and the output is countless times higher than the current salt cooking method. There are very good beaches in Nantuozi Island. I think it is a salt field on Nantuozi Island. It doesn't need to be too big, so it's almost enough for us to need it." The salt court has always been tightly grasping this salt, and selling private salt that is more than one stone is a death sentence.

Although Li Guan only planned to supply Shamen Town Army and not sell private salt, this was a matter that violated the laws of the court, especially now that there is a military supervisor next to him, it is difficult to do too much.

Unexpectedly, Zhang Chengye was very happy to hear that there was such a good method of producing salt. He didn't care when he heard that Li Guan was making private salt. Instead, he squinted his eyes and said, "I think if the salt she exposed can really be compared with green salt, it's better to make a few more pieces of salt in the salt field and dry more salt. This will not only serve the military and civilians of the town, but also give the excess to the emperor."

Li Guan couldn't help laughing at the loyal military supervisor who never forgot to bring this thing to the emperor, but since the military supervisor said that, Li Guan wouldn't care even more. Anyway, it would be a little bit of exposure, and it would be a little more exposure. Without capital, just a little manpower transaction, if it could really be used to please the emperor, it would be very worth it.
