However, when the military industry initially emerged in Taoqiu, Dai Yan found something that made him extremely dissatisfied!

That is, the self-proclaimed spokesman of capitalism was actually stuck in the neck by the industrial products of other countries! This country is Korea, and this industrial product is iron!

South Korea, as a country about the size of the Song Kingdom, faces a more sinister international environment than the Song Kingdom, but it can become one of the powerful countries in the world at this time, for no other reason, relying on its occupation of Yiyang Iron Mountain, which can produce and monopolize more than ninety percent of the world's iron supply!

Whether it is South Korea in this era, or South Korea, which claims to be a "cosmic power" in later generations, Dai Yan does not like it. The logic of the pen ~ fun ~ pavilion www.biquge.info "cosmic power" is very unique: as long as you have occupied me, then yours is mine! Under this unique logic, the entire universe is theirs! And in South Korea in this era, the reason why Dai Yan also doesn't like it is that they are too shrewd!

South Korea's diplomacy relies on the word "qiao", and they do not always maintain neutrality like Song Guo, but constantly swing between countries. And whether it is for themselves or their opponents, they are all "skillful".

Take South Korea's reform as an example, Shen Buxiao's reform and Qin's Shang Ying's reform were almost at the same time, but after the Shang Ying's reform, Qin became a powerful country in the world, but the results of Shen's reform were directly lost in the first war with Wei! The reason for this is nothing more than the technical governance implemented by South Korea, which has never cared about what can really enhance the country's strength!

And it can be said that it died on this in the end. It spent a lot of effort to send the spy Zheng Guo to Qin to repair the Zheng State Canal, hoping to delay the pace of the Qin State, but did not want to make the Qin State Guanzhong a real fertile field, which made the Qin State greatly strengthened, and finally had the strength to sweep the world! In the end, he dragged other five countries to bury him, this is the style of South Korea!

Among the crossbow arrows used by Dai Yan's ration for the boatman, the arrows were all iron from Korea! When he proposed to South Korean officials and businessmen that he hoped to purchase large quantities of Korean pig iron, South Korea immediately refused.

Korean businessmen proposed that Korean iron can only be sold as a finished product! In other words, South Korea will only sell finished crossbow arrows, and will never sell unprocessed pig iron!

If the crossbow arrows sold in South Korea are of acceptable quality, then it's okay to say. The point is that the arrows they sold to Taoqiu were not suitable for the crossbow arrows of the bed crossbow in themselves. And the most important thing is the arrows they sell, and a small half of them are not qualified!

This is definitely the South Koreans who saw that Tao Qiu only had money, and did not have the strength to do it deliberately! Dai Yan guessed the truth of the matter with just a little speculation. Korean crossbow arrows are famous all over the world. At least Dai Yan, as the son of the Song Kingdom, has been to various surrounding countries, and everyone's evaluation of Korean crossbow arrows is extremely good. However, there were so many low-quality crossbow arrows sold to him, it was obvious that South Korea was deliberate.

Therefore, after Dai Yan got the Korean crossbow arrows, he had to redo most of them and recast them into more suitable crossbow arrows. And in order to cope with the more fierce war with the water bandits, Dai Yan had to take out some of the copper that could have been used to issue coins and directly make crossbow arrows!

In later generations, this would be the equivalent of using gold as the shell of a cannonball! Even if Taoqiu is now extremely rich, this kind of consumption makes him extremely painful!

Because of this, he held a grudge against South Korea!

While he was considering the question of iron, he was particularly disturbed by another piece of news about the Taoqiu.

Under Dai Yan's rule, Taoqiu quickly began to prosper, and the number of people from all over the world began to grow rapidly. Thanks to the good foundation laid by the whole Taoqiu when Dai Yan first came, the water supply has tap water, and the grain has the grain of the whole world.

However, there is another important thing that has caused chaos in the whole Taoqiu, and that is fuel.

It is often said that there is no stability without food, but for a mature society, without sufficient fuel, it will also be unstable!

Malthus, a famous economist in later generations, believed that human development is limited by four kinds of resources, and if these four resource limitations cannot be solved, the development of society will inevitably be hindered. These four resources are: food, fuel, fibre (raw material for clothing), and building materials.

Taking this law as an example, the dynastic change that China suffered every 300 years in later generations is actually because food resources limit the development of society. If the whole dynasty can't solve this problem, then the whole regime can only collapse, and then the population will be consumed to a certain extent through a large-scale civil war, and the world can continue to be stable!

This is known as the "Malthusian trap".

And the problem of fuel, although not to the point where food can directly affect the rise and fall of the empire, is not much worse than the problem of food for the development of society!

Today, most of the inhabitants of Taoqiu burn firewood, while a small number of wealthy merchants burn charcoal. And there is actually only one source of these fuels: the forest outside Taoqiu City.

The area around Taoqiu was developed earlier, and nowadays, there are not many forests near the city. Patches of forests, in addition to some nearby hills, still exist, the largest piece of land is next to Heze.

According to the report received by Dai Yan, a large number of ordinary people in Taoqiu went out of the city every day to go to the forest next to Heze to collect firewood. The actions of the common people on such a large scale are obviously a waste of the efficiency of the entire city!

And the rapid increase in population has also caused the forests outside the city to decrease rapidly at a speed visible to the naked eye, Dai Yan has no doubt that if Taoqiu continues to develop like this for more than ten years, all that can be seen outside the entire city is probably a desolation!

And the loss of forests also poses a serious problem: it limits the development of shipbuilding.

Since the new building ship built by Dai Yan has achieved remarkable military results, many businessmen have also set their sights on this new type of ship. Dai Yan had no intention of eating alone, and after patenting several new designs on the ship, he approved the plans of other businessmen to build a shipyard in Taoqiu.

Two shipyards were soon established throughout Taoqiu, both of which were run by wealthy merchants. And as soon as their shipyard was built, they joined the battle for the forest outside the city!

Shipbuilding is at the heart of Taoqiu's shipping industry, which in turn is about Taoqiu's ability to obtain resources from the outside world. As for the forest outside the city, Dai Yan did not dare to arbitrarily ban it, prohibiting the people of Taoqiu from cutting it down.

Dai Yan has not forgotten what happened to King Zhou Li, the first king who dared to ban Shanze, and what happened to the later Qin Empire's ban on Shanze! As for the problem of fuel, as a traverser, he wants to solve this problem through economic means.

When Dai Yan was still in Fengyi and founded the scientific school, he once sent a large number of disciples of the Mo family and peasant families to the whole Fengyi to investigate and explore the resources of various places. Later, there were not many discoveries in Fengyi, and Dai Yan did not recall these people, but issued them documents to prove their identities, allowing them to continue to explore throughout the Song Kingdom.

Prospecting is actually a sophisticated industry, and Dai Yan had no contact with it in his previous life. His request for the Mojia and the farmer exploration team was nothing more than to mark the locations of the more special ores in various places, and then bring them back to Fengyi and Taoqiu for careful study.

After so many years of exploration, the disciples of the Mo family finally achieved some results. When they brought back a black stone, Dai Yan almost jumped up with excitement: Isn't this coal!

And following the rough stones of these coals to Dai Yan's eyes, there were also some dark red stones, when Dai Yan personally verified them from the experiment, he found that this was actually an ore containing iron!

Although the iron content in this is very low, it is considered an extremely garbage "poor iron mine" in later generations, but Dai Yan didn't care about it at all! As far as he knows, at least 90% of the iron ore in the entire land of China is poor iron ore, and in the current Song Kingdom, it is extremely good to be able to find poor iron ore!

With coal, Taoqiu was able to get rid of the constraints of fuel resources on urban development; With iron, Dai Yan can kick the South Korea that disgusts him away! How could he not be thrilled by the fact that these two surprises were coming at the same time?
