The collapse of the domestic economy and the construction of trade barriers by various countries have completely blocked the gaps in the international market that several defeated countries in the First World War can only use. In desperation, these countries had no choice but to negotiate with several countries, including the Yaman Empire, to demand that they fulfill their allied obligations, that the two sides cancel tariffs, and that resources be shared with the colonies.

The representatives of several defeated countries were extremely angry at this, and they immediately said that their countries would immediately break away from the Allied bloc and no longer recognize the peace treaty signed at the end of World War I.

For the secession of several countries, the Yaman Empire and several other countries are quite angry, but now it is difficult to protect themselves, where is the ability to carry out a war of aggression, if several countries are forced to rush, they are all invested in the Boston Empire, then the strength of the Boston Empire will be able to compete with the Chinese Empire, and the weakest Allied group will have nothing to do with them at all.

In the end, the Allied bloc did not pursue a few countries that broke away from the group, but these countries were determined to do a big job. On May 7, 919, the Saar Empire and the Nantes Empire sent troops into the island of Ireland and Amiens respectively on the same day, which was already a blatant tearing up of the Treaty of Essen and not recognizing the post-war situation, but neither the Chinese Empire nor the Boston Empire made any statement, as if they had not seen it.

Even if they tore up the Essen Treaty, it would only provide a temporary boost to domestic morale, and it would also do little to the domestic economy, which continued to decline rapidly, and within a year the economies of the defeated countries had almost slipped to the bottom, and the government was already on the verge of bankruptcy.

In this wide-ranging economic crisis, NATO, led by the Chinese Empire, watched from the sidelines, and at this time everyone admired Fang Ruijun's wisdom, and if the Chinese Empire followed suit and implemented the quantitative easing policy, I am afraid that the loss would not be small.

Now the Chinese Empire has sharply raised tariffs, relying on a population of more than 1.5 billion at home and as many as 600 million in its allies to avoid a crisis. With this living water of domestic demand, relying on the steady development of the domestic economy, the whole country was not subject to too much economic fluctuations, even in 919, when the economy of other countries was the most difficult, the Chinese Empire still achieved a high economic growth of 7%, while the economies of other allies were equally stable.

In addition to NATO, other countries that have been persecuted by the economic crisis have begun to seek ways to revive their economies, and many high-level government officials have begun to turn the solution to the economic crisis to the military industry. The military industry is a very good way to stimulate economic growth in the economic crisis, because the military industry involves many types of industries, and once the military industry prospers due to the state's orders, it can revive a large number of domestic heavy industries such as iron and steel, shipbuilding, etc., and naturally can also stimulate the recovery of the domestic economy.

But this method also has a very serious consequence, after all, weapons and equipment do not produce anything, their only use is to fight wars, if the country buys too many weapons, it will cause excessive maintenance costs, and the country's economy is in danger of collapsing again. At that time, the only way for the country to get out of the crisis was war, which was how the last World War began.

Although they are well aware of the magnitude of the damage, the few countries that were defeated in the last war can no longer care about this, and if they do not stimulate economic growth, their governments will collapse before the war begins. Naturally, it is impossible to make backward weapons, so several defeated countries began to contact the Chinese Empire, hoping to buy military skills, but the Chinese Empire sternly refused on the grounds of maintaining peace in the world.

In desperation, several countries targeted the Boston Empire, which was second only to the Chinese Empire in terms of science and technology, and in order to win over these countries, the Boston Empire happily agreed to the request, and they even sold a large number of drawings of active weapons to several countries.

With sufficient military skills, the Saar Empire and the Nantes Empire began to frantically expand their armaments, using two-stage turbocharging and reaching a speed of 758 kilometers per hour P51 Mustang dual-use fighters and four-engine B29 long-range bombers began to equip their troops.

In addition, due to the expiration of the Rome Convention, in order to rely on the military industry to boost the economy, all countries have no idea of continuing to sign follow-up treaties, and a large number of aircraft carriers, battleships, destroyers and submarines have started construction. In addition, the Boston Army's M14 semi-automatic rifle, M4 and Hellcat destroyers are in production. Relying on loans from the Boston Empire and the construction of a large amount of equipment, the national industrial system was pulled up, and the economies of several countries began to improve.

Even the Boston Empire was also affected by the economic crisis in the Western Continent, and their method of relying on the status of the Boyuan Shilu Boundary Currency to pass on the economic crisis not only did not succeed, but was pulled down by the other party's deeper economic crisis, which is also the reason why the Chinese Empire did not turn Huayuan into the World Continent Currency. The Chinese Empire's economy was in good shape, and it was completely self-contained, without the need to control the economy of the world, and at the same time avoided the danger of being affected by the economic crises of other countries.

After the frenzied arms race before the First World War, the countries were naturally very aware of the consequences of mass military production, and in order to prevent problems before they occur, and in order to get rid of the domestic economic predicament, the Allied countries and the Boston Empire began to expand their armies, and the upsurge of the arms race was ignited again.

The Chinese Empire did not expand its army, and due to the good economic atmosphere at home, the economic crisis did not do much damage to NATO, and before the economic crisis appeared, Fang Ruijun, who had been prepared, had already asked NATO countries to raise tariffs, so the dumping policy of Western countries on surplus products had not yet begun, and only the part of exports was affected within NATO.

For exports, the most affected is the Chinese consortium, especially the largest export volume of electronic products, almost completely unsalable, but the loss of the embankment outside the embankment, although countries quickly erected high trade barriers, but people need to eat, no country will be with food, especially the lack of food countries, so food is the only zero-tariff product. The poor export of electronic products can reduce the price of electronic products in the country, and the difference in the price lost is made up by selling grain abroad.

At this time, Fang Ruijun's steady economic policy has shown its effect, the economies of various countries have collapsed, while NATO is quite calm, and the only little economic fluctuations have nothing to do with the overall situation, and Fang Ruijun timely suggested that Congress overhaul water conservancy projects in the country, strengthen and renovate some old projects built more than ten years ago, and build hydropower stations on several major rivers at the same time to solve the increasingly tight power supply in the country.

In addition, the Chinese Empire has increased its investment in wind and solar power generation, hoping to reduce the scale of thermal power generation and reduce air pollution. While carrying out industrial reform and economic restructuring, Fang Ruijun did not forget to invest in the army, and new equipment began to be put into active service in an appropriate amount, of course, the scale is not as crazy as other countries, but it is also very much for a country.

First of all, the navy, due to the expiration of the "Rome Convention", countries have no intention of signing new treaties, the Chinese Empire can also begin to let go of its hands and feet, and build warships on a large scale, so on the basis of the three aircraft carrier formations with three 60,000-ton 'General' class aircraft carriers as the main force, the Chinese Empire began to build a new generation of new aircraft carriers with a full load displacement of 94,000 tons.

The aircraft carriers of the Chinese Empire have always been named after people, so there will be ranks such as county guards, governors, and generals, and this time the aircraft carriers of the Chinese Empire are named after the emperor of the Nanming Dynasty, so this type of warship is called the 'Nanming' class.

The Nanming-class aircraft carrier is 342.3 meters long, 40.5 meters wide, has a draft of 11.9 meters, and has a personnel establishment of 3,215 personnel. The most surprising thing is that the 'Nanming' class aircraft carrier uses two metal hydrogen reactors that have just been developed as power systems.

Metallic hydrogen is a very strange thing, but as early as the age of the earth this substance has begun to be studied and has results, hydrogen is a non-metallic element, ordinary hydrogen molecule is made of two hydrogen atoms, each hydrogen atom has only one electron, the two hydrogen atoms that make up a molecule share those two electrons equally, there are no remaining electrons.

But after ultra-high pressure compression, hydrogen atoms can be so tightly packed together that each atom is surrounded by a dozen adjacent atoms. As a result, a single electron of each hydrogen atom, regardless of the abnormally strong force of attraction in the nucleus, may begin to slide from one neighboring atom to another. This way you will get metallic hydrogen.

In order to force hydrogen to be so tightly bound together, the hydrogen atoms must be in a near-pure state (the presence of other atoms will interfere), and not at too high a temperature (which will cause it to expand), and the hydrogen atoms must also be under tremendous pressure.

The closest thing to satisfying these conditions in the solar system is at the center of Jupiter, whose interior is made of metallic hydrogen. Metallic hydrogen is usually produced on Earth by physical methods such as making ultra-high pressures, but such metallic hydrogen can only be produced in laboratories and is structurally unstable.
