Time came to the 42nd year of Konoha in a blink of an eye, and this year important characters such as Obito, Rin, Sunset Red, Silence, and Asma officially graduated from the ninja school, marking the new generation of ninjas after the Second Ninja World War officially stepped onto the stage of the ninja world. At the same time, the young ninjas of the previous generation have grown to their heyday and become the pillars of each village.

For example, the parents of the twelve little strong, Shinnosuke, Hikari, Watergate and other leaders of the younger generation have all grown into ninjas, plus the other new generations who have experienced the second ninja war have basically become ninjas, Konoha's top and backbone are sufficient, as a foundation for ninja is because of the endless educational reforms, as long as you are willing to pull up a regular ninja army with more than 400,000 troops at any time. If you recklessly recruit the Mavenko ninjas, you can even pull out a ragtag army of millions of people.

In addition, because Konoha takes turns to train all martial ninjas every year, the quality and discipline of the 400,000 regular ninja army far surpass that of ninjas from other countries, and they belong to the elite troops in the entire ninja world.

Now the number of Konoha ninja troops has more than tripled compared to the Second Ninja World War, and more importantly, the quality of ninja has increased instead of decreasing.

Although the other four ninja villages have developed rapidly in recent years, most of the new ninjas are lower ninjas, and the middle ninja and the upper ninja have suffered heavy losses in the last war, so the successor is weak, and the lack of backbone of the upper ninja has led to a significant decline in the average combat power of the ninja armies of various countries.

And the fastest way to improve the quality of the ninja army is to conduct actual combat, so countries have launched low-heat battles against neighbors, and a large number of lower ninja squads infiltrate the enemy's borders every day, which is not only for training, but also for the rehearsal and test of the official war.

And the Fire Country is in the center of the ninja world, and the border is the largest, so naturally after being harassed by various countries, it has to join the low-heat battle. A large number of ninja squads were sent to the border for defensive patrol missions, even the newly graduated Shinobi.

Fortunately, the average strength of the Konoha ninjas far exceeds that of the major ninja villages, coupled with the environmental and logistical advantages, they did not suffer in this small-scale battle, although occasional casualties were inevitable, but after actual combat, the new generation of ninjas were growing rapidly, so they did not suffer in this war rehearsal, but occupied the biggest advantage.

This also made countries realize how strong Konoha was, and they didn't dare to start a big war easily.

Although the borders of the ninja countries are becoming more and more tense, the mainland is still at peace, and even the economy and trade have not been affected in any way. Such skirmishes will continue for a long time, and a full-fledged major war will not break out immediately.

Although the war was still in full swing, it was inferred from the graduation time of Obito and others that World War III was not far off.

In addition, according to the intelligence of the Shadows, the Red Sand Scorpion of Sand Hidden has become famous as a genius ninja in the new generation, and his parents also died at the hands of White Fang during a mission just like in the original book.

Therefore, Rope Tree deduced that there were still at most three years before the official outbreak of the war, and the first shot must have been fired by Sand Hidden Village, so Rope Tree ordered the Dark Branch to pay close attention to the news of Sand Hidden Village, so as not to be attacked by Sand Hide like in the original book.

Although the reform of the Fire Nation has been going very smoothly in recent years, and the development of the ninja school has been getting faster and faster, it is no longer possible to complete the Chakra Industrial Revolution before the war breaks out completely.

However, Orochimaru's scientific research department is not completely fruitless! Through several years of research and experiments, coupled with the knowledge provided by Rope Tree, Konoha has made a major breakthrough in the technology of wind escape aircraft!

Although the aircraft of the Sky Country are very flexible and convenient, they have great shortcomings in range and load!

Relying on the small arms held by the pilots could not shoot at a distance of more than 100 meters, and the weight of the bombs carried could not exceed 10 kilograms.

Aircraft are nowhere near as powerful as World War II fighters and bombers! Therefore, Rope Tree deliberately put forward a proposal to make the aircraft larger.

In fact, it is more difficult to miniaturize the aircraft as a monolith, and the technical requirements are higher. The original technology of the country of the sky was completely capable of making airplanes, but it has been limited by energy problems and has not been able to achieve it.

The zero-tailed splitting body provided by the rope tree is a perfect solution to the energy problem, but the research direction he proposes is not an airplane but an airship!

Because the power of the Wind Chakra far exceeds the propeller of the aircraft, and it can also be converted into buoyancy, it is very suitable for making larger airships, which not only do not affect the flight speed, but also have a larger load and volume. Whether acting as a civilian transport or a military combat weapon, airships have an even greater advantage.

Any high technology will be invested first and foremost in the military, not in civilian use. Although the commercial trade of the Fire Nation would develop rapidly if the airship was put into commercial transportation, considering the current form of the ninja world and the cost issue, Rope Tree decided to use the airship as a secret weapon of the Konoha Air Force and not use it in transportation for the time being.

Of course, the shape of the airship is not the usual cigar type, nor does it provide buoyancy with hydrogen, but an angular and streamlined shape that looks more like a spaceship flying in space. When flying, the entire hull will be wrapped in an invisible wind escape, which is no less than that of an aircraft, far exceeding the Skywalk Fortress.

In addition to its flight speed, the airship also has a large number of small laser guns installed on it as long-range weapons, and can carry more than hundreds of kilograms of bombs, which can be used as large bombers.

In addition, the airship is large enough to carry hundreds of pilots, acting as an aircraft carrier, and can also serve as a frigate for a celestial fortress.

With the combination of various advantages, the airship can be used as a multifunctional aviation weapon, and there are no obvious drawbacks, and it can be used as the main warship of the Konoha Air Force for a long time in the future, and it is difficult to be eliminated.

Therefore, after the successful sea trials, Rope Tree ordered the military factory under the Konoha Foundation to go all out to produce hundreds of new airships. Although the Chakra Industrial Revolution is not yet complete, the modern industrial system is fully capable of building Chakra weapons, and the previous Flying Machines and Skywalker Fortress were produced using modern industrial technology.

Moreover, in order to maintain confidentiality, all personnel in the military factory must be strictly monitored and audited, and the secret department is responsible for the confidentiality work.

With the experience of the Second Shinobi World War, the entire ninja world attaches great importance to the Air Force, so the ship-building plan of the Rope Tree is supported by all the Konoha high-level officials.

Of course, with the current power position of the Rope Tree, it is completely possible to build in the name of the Shogun Shogunate, but the military side is always in charge of Konoha, as a ninja, the Rope Tree must maintain the authority of the Hokage, and he cannot leave Konoha alone until the last resort.
