Online Game: Island War

In addition to ironmaking, which is an important technology related to weapons and equipment, as well as the national economy and the people's livelihood, a large number of basic technologies have also been researched.

For example, in agriculture, the early industrial preparation of chemical fertilizers such as urea and diammonia, the production of early agricultural pesticides, and so on.

Fortunately, cross-breeding, which requires a lot of time and experiments to improve yield, has not been systematically added to the research center.

Lei Jiu was still hesitant about whether to put chemical fertilizers and pesticides into actual agricultural production.

On the one hand, chemical fertilizers and pesticides are indeed powerful means of boosting agricultural production, and the increase in yield per mu is not inferior to the breeding of new hybrid grains.

On the other hand, long-term use of chemical fertilizers will lead to land compaction. And in terms of health, chemical fertilizers and pesticides are more or less influential.

Even the green agriculture, ecological agriculture, and pollution-free agricultural products advocated by modern society are protected by chemical fertilizers throughout the whole process, otherwise the output cannot be guaranteed at all.

It's just that compared with traditional fertilization and spraying, green ecological agriculture is more rational in the selection, use time and use of chemical fertilizers and pesticides.

Chemical fertilizers and pesticides, the former increases yield by directly improving soil fertility (the main element needed for crop growth), while the latter ensures normal growth of crops without reducing yield through insect resistance, disease resistance, and damage resistance.

Without these two things, it is not just the citizens of backward countries in some regions who are hungry.

People, first of all have to eat enough to have the energy to pay attention to other things.

Therefore, for a power, feeding the stomachs of its people is always the top priority.

The current food pressure on Huanghuang Island is not great. Although the island's current population exceeds 4 million, the successive years of bumper harvests have greatly increased the food reserves.

The grain seeds provided by the system at the beginning were high-quality seeds. At least Lei Jiu didn't have to start with the most primitive grain seeds. In addition, the land was extremely fertile. For at least ten years, he didn't have to worry about reducing production due to insufficient land fertility.

In terms of yield per mu, Huanghuang Island is not inferior to modern grain production.

Moreover, among the landforms of Huanghuang Island, the area of ​​land suitable for cultivation exceeds half of the island's area, which currently covers 60,000 square kilometers, equivalent to 90 million mu.

The arable land area of ​​China as a whole on the earth is only a little over 2 billion mu.

The arable land area of ​​Huanghuang Island is equivalent to one-twentieth of it, and the grain yield per mu is not much different. By the end of this year, the grain harvested on Huanghuang Island will reach a very exaggerated figure.

Even if China imports a lot of grain every year, even if the Chifa species, which account for half of the total population, can eat up to 5 people, with the current grain output of Huanghuang Island, it is still no problem to feed 15 million+ people.

But... Although Lei Jiu really hopes to develop the population within the 10-year population refresh time, it is not as good as the beginning period after all.

If there is no food, everyone can eat fish.

Once a natural disaster causes one or two crops of grain production on the island to be reduced or not harvested, he will be numb at that time.

Although the god of the sky is also included in the public sacrifice, the probability of natural disasters has been greatly reduced.

But...to prevent the bad quality of the system like convulsions, Lei Jiu felt that the island must at least have enough food storage to ensure the current population can eat for two years.

Otherwise, once there is an island-wide catastrophe...

So this year's population development plan, the total number will not exceed 10 million, and Lei Jiu is inclined to the value of 9 million, or even less.

Because he still doesn't know how many adventurers will flood into the player's resident city. After all, these adventurers and players also need to eat, and the food supply in the city is naturally guaranteed by Huanghuang Island.

However, in view of the scarcity of meat on Huanghuang Island and the relatively high transportation costs of the player's city, these living supplies are more expensive, presumably adventurers and players should not care too much.

In addition, some basic chemical and basic mechanical technologies have also been unlocked, such as the artificial soda method.

Now the alkali on Huanghuang Island is provided by two trona mines discovered later, the output is not high, and the reserves are not too large.

But at least in terms of food, Lei Jiu no longer needs to endure sour dough.

Mechanical technologies are all manual labor machines that are not very efficient, such as manpower, animal power, water mills, spinning machines, and looms before the industrial revolution.

There are many restrictions on light industries related to people's livelihood and production, but not many restrictions on heavy industries.

As long as players can make breakthroughs in several key points in steelmaking and energy, basic applications can be rolled out.

For example, the previous conqueror ship, as long as you can get enough steel and research the engine, the system doesn't care what kind of power you have, and it can run on the sea.

The crystal car and railway network that Lei Jiu conceived before are also based on these.

Of course, ships can be built, crystal cars can be built, and even miniaturized cars can be built to carry people and loads. However, if the manufactured things want to be upgraded and updated, they must be improved in terms of materials, machinery, etc. funded research projects, otherwise you'd be stuck with this primitive old-fashioned equipment.

Like the several Conqueror ships that were built before, they were fine for the first half a year after they were launched, and then there were frequent problems. Although they were basically minor problems, they had to be overhauled once they returned from the voyage, which was quite troublesome.

Some problems are related to materials, which age quickly and must be replaced frequently. Some problems are related to craftsmanship. The durability is not very good and requires frequent repairs. Of course, there are also design problems. This will have to wait until the next batch of ships are manufactured. Only then can it be modified.

However, in view of the huge steel consumption of ships, and the fact that there is no technological innovation that can improve the performance of ships in the short term, Lei Jiu has no new shipbuilding plans in the short term.

Although the players live on the island and are surrounded by the ocean, because the power density on the sea is too sparse, the performance of the ships that the players can build is really limited. For the time being, the enthusiasm of the players for the development of the navy is generally not high.

Generally speaking, the research center's investment projects cover a wide range of areas, and some seemingly unimportant technologies may suddenly be needed at any time.

In order to avoid the embarrassing situation that it will not be unlocked when it is suddenly used in the future, and it will have to wait for several years, Lei Jiu will invest in all new research projects that will be highlighted next.

Although this will further increase the fiscal deficit, Lei Jiu, the leader, said that these expenses cannot be saved.

Besides, the more technology is unlocked, the overall strength of the island will also increase, and the monthly ranking of the overall strength of the island will reward gold coins according to the overall value of the island.

Anyway, these technologies will have to be invested sooner or later, and it is a good thing to invest in such an early investment and get money, of course Lei Jiu will not refuse.

Of course, the premise of all this is that he has enough spare money in his hand, otherwise all talk will be over!
