At present, among the countries of Blue Star, the industrial scale of Daheng is actually not small, after all, the land area, resources and population are placed there.

In terms of industrial scale alone, it is actually relatively large, even if it is affected by the melee of the feudal town, but just the internal market demand of Daheng is enough to maintain a large-scale industrial system.

However, this industrial system is very backward, especially in civil industrial products, the technology of various products is several levels behind other first-class powers in Bluestar, and even the second-rate technical level is not even available.

As for the trade blockade of Daheng by other countries in turn, what is it, Daheng has all resources and markets, and basically does not rely on international trade to live, and the only main export commodity is grain.

And even if it was grain exports, it was also during the civil strife in the feudal towns, where the feudal towns looted grain in order to raise military expenses, and then exported it in exchange for funds.

Now Lin Ziran has not engaged in large-scale grain exports in exchange for funds, so the amount of grain exports has dropped significantly, and food is a thing that the whole world needs, if you don't import it, there will naturally be countries that lack food to import, and even when necessary, you can also use grain exports in exchange for more benefits.

In the past two years, Nanhai Prefecture has also exported some new kerosene and weapons, kerosene is also a commodity that has no competitors, other countries have not discovered large-scale oil fields for the time being, if you want to use cheap kerosene, you have to find Daheng people to import.

In addition, the key point is that even the export volume of kerosene is getting smaller and smaller, only 1,000 barrels of kerosene were exported last month, and it was exported to the nearest Kingdom of Dynaudio in the south.

This is not because other countries refuse to import kerosene, but because the kerosene production capacity in Nanhai Prefecture is also limited, and with the expansion of the domestic control area, the internal sales volume is also increasing, and now Tsingshan Petroleum Company produces about 40,000 barrels of kerosene every month, which is basically used to supply Daheng's internal market, and it is not even enough.

It's not enough to produce and sell it, and it doesn't matter if you export it or not.

As for weapons and equipment, they are only exported to the Orr Kingdom, which is a very special country, surrounded by enemies, and other big countries have no good impression of this kingdom, and they have been thinking about annexing it all day long to occupy the gold.

In addition to being able to buy 10,000-ton ironclad ships and rear-loading guns in Nanhai Prefecture, it really can't buy such a large amount of advanced weapons and equipment in other places.

Grain, kerosene, and weapons are the only three main export commodities of Daheng at present, but these three export commodities are very special, and even in addition to weapons, the export volume of grain and kerosene is gradually declining, so the export of the entire Daheng is actually very limited.

Exports are limited, especially the export of ordinary civilian industrial products is almost equal to zero, and Daheng does not import much agricultural and livestock products or ores from other countries, and when industrial products are not imported, Daheng naturally does not care much about the trade blockade of other countries.

There's no trade at all, what's the blockade!

It is also thanks to the trade protection policy and official capital policy of Daheng Domain that the current Daheng can maintain a civilian industrial system with acceptable scale but seriously backward technology.

Relatively speaking, the national defense industry system is much better, after all, the national defense industry is used by the feudal towns to fight wars, grab territory, and maintain their rule, and if the technology is too scum, it will be killed by others, so many feudal towns attach more importance to the development of national defense technology.

However, even so, even if the national defense industry technology in Daheng is fully integrated, the technical level will be at the level of the first-class end, but some basic technologies, such as materials, processing technology, etc., which have a relatively large gap compared with other powers.

Now that the rear-loading guns have come out, even the Jingzhou Machinery Bureau knows that it is imitated and mass-produced, not to mention other first-class powers, these first-class powers will soon be able to complete the imitation production of loading weapons with a deeper technical background, and even go further, and finally complete the transcendence of the Daheng unified army.

This kind of thing, Lin Ziran naturally can't let it happen!

Therefore, although the domestic unification war has not yet ended, Lin Ziran is already considering the subsequent upgrading of weapons and equipment for the army and navy, the navy has the unification armored ship, and the army has the Luoan IV rifle, the new 150-mm field gun and the new 75-mm field gun and other new equipment.

Strictly speaking, these weapons and equipment were not prepared for the war of domestic unification, but for subsequent foreign wars.

As for why we are in a hurry to prepare now!

Daheng has its own national conditions here!

Before the reunification of this country, there are countless people among the people who are clamoring for reunification and then wave their troops south, first clean up the two traitors of the Kingdom of Danor and the Kingdom of Kassi, and then continue to go south to the Olisa Empire, completely control the Endless Strait, and then seize countless territories of the Olisa Empire, and obtain more land for the people of Daheng.

This is not a public opinion propaganda created by Lin Ziran for the sake of his own reunification war, but a spontaneous public opinion among the people.

After the unification of the Great Heng people, they will expand externally, which is an old tradition of thousands of years, a little bit of the history of the Great Heng people knows, the Great Heng people themselves know, and the people of other countries on the Blue Star also know.

Now I don't know how many Daheng people, especially the second sons of peasant families who are eager to get their own land, and the second sons of powerful people who are eager to make contributions, are all waiting for Lin Ziran to expand externally after unifying the empire!

In the same way, many countries are now nervous and start preparing for war!

Among the many countries, the alliance of the six northern countries and the Olisa Empire in the south are the most afraid of the reunification of Daheng.

As soon as Lin Ziran launched the Northern Expedition, the alliance of the six northern countries had already reached a new agreement with each other on armament warfare, and the internal countries began to increase the number of troops stationed in the 'West Sea Corridor' in the south of the Qushan Kingdom, and jointly funded the renovation of the West Sea Corridor defense line to make it more suitable for defending against rear-loading rifled weapons.

The Olisa Empire in the south began to send troops into the Kingdom of Dyna to assist the Kingdom of Dyna in building a land defense line, and had frequent contact with the Six Northern Alliances, trying to reach a real strategic alliance with the Six Northern Alliances - a strategic alliance against Daheng.

At the same time, within the Orissa Empire, a new phase of army and naval expansion plans has been announced.

This includes investing in the construction of a number of 10,000-ton warships, expanding the number of standing armies, and increasing the reserve force.

They want to further increase the strength of the army and navy to dispel the damned, barbaric Daheng people from trying to launch a second southern invasion.
