During sea trials, both countries discovered that destroyers have faster speed and better agility than cruisers, and are indispensable for reconnaissance, anti-submarine and escort missions.

Therefore, both countries accelerated the design and construction of new destroyers, and with the experience of the design and use of the first type of destroyer, they decided to put torpedoes on this type of warship, so that it could threaten large warships.

The construction of destroyers has caused the loss of submarines to skyrocket, especially after both countries have desperately started to build destroyers, and since the submarines of both countries are under development, large-scale construction cannot be carried out in a short period of time.

In order to maintain the increasingly tragic war, they had to grit their teeth and import from the Chinese Empire, so that a steady stream of submarine orders was what Fang Xiaoyu could not ask for, and while selling submarines to the two countries, the submarine factory of the Chinese consortium made a windfall.

It was at this time that the Boston Empire asked for help from the Saar Empire, and in order to speed up the construction of destroyers, the Saar Empire finally decided to transfer relevant information to the Boston Empire.

The information on these transfers includes the Sahr Empire's full set of construction techniques and experience in the design and construction of destroyers, but this transfer of technology is conditional, and in the future, the Boston Empire will sell one destroyer to the Saar Empire at a low price for every two destroyers built.

Because Zhao Qi fought this beautiful sabotage battle, the Boston Empire understood the tip of the iceberg of the military strength of the Chinese Empire. In the face of the Chinese Empire's completely different military strength from the previous intelligence response, the Boston Empire had to re-evaluate this powerful opponent, and they took the opportunity to pick up the bargain and waver a lot in their idea of attacking the Chinese Empire.

At the court meeting, the intelligence department first made a situation report to the important officials of the Manchu Dynasty, and obtained this relatively real information, and the officials had their own opinions, and finally they agreed that the war against the Chinese Empire would outweigh the losses.

Now due to the chaos in the Western Continent, the domestic economic form of the Boston Empire is very good, and it is the time to develop national strength and expand the industrial base, and once war is declared on the Chinese Empire, not to mention that the Boston Empire has no certainty of victory, even if it can win, it will be a disastrous victory, not to mention that it will not reap the benefits, and it will destroy the economy that has been revived with great difficulty.

Later, the Boston Empire secretly submitted a note to the Japanese state, stating that it was not ready for war and could not go to war against the Chinese Empire. After receiving a note from the Boston Empire, Okuma Shigetomo was full of bitterness, unable to imagine that the Boston Empire had always supported the Japanese and instigated them to wage war against the Chinese Empire, but at the critical moment, the Bostonians themselves retreated.

The current government of the Japanese state has a feeling that it has been betrayed, and without the support of this important ally, the Japanese state has lost all hope of victory, not to mention that after the war between China and Japan, the tactics of the Chinese empire surprised the Japanese navy.

Originally, the Japanese state believed that it had a huge naval advantage in a short period of time, and even if the army could not defeat the other side, but if the navy had an advantage, the Japanese army could threaten the major ports of the Chinese Empire at any time, while the Chinese Imperial Army, which had no sea supremacy, could only be exhausted and defend every port that could be attacked by the Japanese army.

At that time, the Wa Kingdom will occupy the initiative, and they can choose to destroy all the coastal cities of the Chinese Empire, just like the last time the Chinese led the fleet against the Wa State, or they can also negotiate with the Chinese Empire on favorable enough terms to get back what they lost in the first two times, but their dream is destined not to come true.

It is true that the Chinese Empire does not have battleships at the moment, but they do not want to fight the Japanese fleet at all. In areas completely unknown to the Japanese government, the Chinese Empire once again took the lead, and they aggressively expanded their air force at home, and at the same time built a large number of airfields in Ezo Province, Iwo Qiu Islands, Goryeo County, and Khai Island, and surrounded the entire Japanese Kingdom with their air force.

All the bombers and seaplanes of the Chinese Empire were deployed to the various airfields of this line, and the seaplanes took turns patrolling the surrounding waters, and whenever they found ships with flags other than the Chinese Empire, they would call bombers to the nearest place by radio, and all the non-Chinese Imperial ships that entered and left the Japanese Kingdom during the day did not give any warning, and were all sunk.

Now the entire world is in a big war, and countries that don't have a big war don't dare to provoke the Chinese Empire. Those ships that were supposed to trade with the Wa kingdom were told to comply with the requirements of the Chinese Empire after being notified to their own countries.

The country did not dare to come forward, and even if the merchant ship owners had great profits, they did not dare to touch this mortal trade voyage, so for a time the trade volume of the Japanese country shrank rapidly, and soon it was completely cut off.

The country is an island country with scarce domestic resources, and both raw materials and products must be imported by sea. The three-dimensional blockade of the Chinese Empire's sea and air made the Japanese almost desperate, with bombers shuttling back and forth during the day and submarines and destroyers patrolling back and forth at night, and in just two months, the Japanese transport fleet was sunk by one-third.

In the face of the Chinese Empire's aggressive total blockade, the Wa Kingdom also wanted to destroy the airfields on these islands through night raids. It is a pity that the coastal artillery and torpedo boat formations of the Chinese Empire worked closely together to make the Japanese navy dare not approach.

The fleet, which had only been attacked by a little delay, would encounter hordes of bombers at dawn, and after losing one 'Kongo'-class battleship and three 'Mogami'-class cruisers, the Japanese navy would no longer dare to attack at night. All navies could only huddle in harbors, relying on small-caliber machine guns made in a hurry, and placing them on shelves as anti-aircraft machine guns to avoid being targeted by the bombers of the Chinese Empire.

In desperation, the Japanese government sent emissaries in the hope of peace talks with the Chinese Empire. However, Fang Xiaoyu personally decreed that unless the Japanese surrendered unconditionally, they would not accept mediation from any side and any form of peace talks, and the Japanese government was speechless again.

Unconditional surrender is tantamount to being slaughtered by others, the Japanese have attacked the Chinese Empire several times, and the people have already hated them to the bone, how dare they surrender, and after there is no hope for peace talks, the Japanese government can only hope for the mediation of the powerful countries in the western continent.

In order to warn the countries of the world not to dare to fight in the Sino-Japanese war, the Chinese Empire took out the four Chinese-class battleships that had already been built and had been hidden, and also announced the construction of four more. The four newly built Zhonghua-class battleships have a considerable warning meaning in the eyes of various powers, in fact, Fang Xiaoyu has another meaning, that is, to attract attention and mix up the new Shannan-class battleships that are being built secretly, which is also Fang Xiaoyu's consistent style.

Now all the great powers and countries are in a big war, and there is no time to take care of anything else, not to mention that now the four Chinese-class battleships of the Chinese Empire have joined active service, and there is no strength vacuum at all in the navy, in the face of such a powerful country, and pinching the materials that are urgently needed by various countries, it is too late for all countries to curry favor with the Chinese Empire, how can they provoke him.

After learning that the Chinese Empire was at war with the Japanese Empire, the Yaman Empire first openly supported the Chinese Empire, declaring that 30 million Japanese people were superfluous, and that such a country with no moral integrity and full of aggressive thoughts should be destroyed.

The Saar Empire and the Nantes Empire also have some friendship with the Wa Kingdom, and in this case, they can only do it without falling into the ground, and as for mediating between the two sides, they are already powerless. In the face of all possible hopelessness for reconciliation, the hard-boiled Japanese government finally decided to stay the course and never surrender even if all the people died.

The stubbornness of the Wa State is also a last resort, and the many confrontations have made it very clear to the top of the Wa State that Fang Xiaoyu is pre-recharged and fast for them, once they surrender unconditionally, in the absence of other powers, the Wa State will be doomed.

Regardless of whether the Wa State is voluntarily tough or not, this matter still makes Fang Xiaoyu very angry, now is the time to go all out to develop and make a lot of money, and it is really uncomfortable for him to have the Wa State involved in the energy.

What's more, Fang Xiaoyu has always thought that the money that should not be spent will never be spent, and when he started to blockade the Japanese country, his purpose was to train the newly built air force, and after a long time, Fang Xiaoyu felt a little distressed.

Airplanes have to burn oil every day to patrol the sea, and this fuel costs money, attacking ships has to drop bombs, bombs also cost money, and with submarines and destroyers patrolling, such a blockade mission really has no end in sight.

Fang Xiaoyu immediately ordered the Navy, Army, and Air Force Joint Command to formulate an operational plan, and he wanted to completely defeat the Japanese state and completely suppress the arrogance of these damned Japanese people. After receiving the holy decree, the bigwigs of the headquarters did not dare to slack off, and the chief of the army general staff, Tobul, the commander of the navy, Liu Junguo, and the new commander of the air force, jointly issued an order, demanding that the general staff departments of the three armed services draw up separate plans for attacking the Japanese.

The bigwigs of the three armed services pressed down on the task, and the general staff departments of the various services immediately began to draw up their own offensive plans, and in just three days, the plans of the three staff departments were handed over. The three bigwigs took a look at it, and as a result, these plans only took into account the combat of their own branches of the army, and neglected cooperation, so the flaws in each plan were not small, and after calculation, at least 50,000 officers and soldiers would be killed or wounded in the fight against the Japanese state.

The bigwigs of the three armed services are well aware that in the future it will be an era of coordinated operations among the three services, and that the method of relying only on one branch of the armed forces to deal with the enemy alone is no longer applicable, and the current combat mode has changed from a flat plane to a three-dimensional one, and ignoring any aspect may lead to the failure of the entire operational plan.

In view of this situation, Tobul, Liu Junguo, and Al jointly signed a petition to hope that Fang Xiaoyu would agree to add a staff department to the joint command, which would be responsible for formulating a joint operational plan for the three armed services and coordinating the three major staff departments, and Fang Xiaoyu immediately agreed.

With Fang Xiaoyu's holy decree, the three major staff departments immediately began to transfer capable staff officers to the joint staff headquarters under the joint command; with the coordination of these staff officers from the three armed forces, a new operational plan was released, which integrated the plans of the three major staff departments and carried out coordination and improvement, so that the feasibility of the plan was greatly enhanced.
