At the same time as the introduction of the industrialization policy, Rope Tree did not forget the reform of the ninja school, because his ultimate goal was to increase the strength of Konoha and realize ninja civilization, in addition to increasing the number of ninjas, but also to improve the quality of ninjas.

First of all, the way to increase the number of ninja is simple, and with sufficient funds, the number of ninja school callups continues to increase every year.

In Konoha 34, the western branch first enrolled 5,000 students, and then the number of students increased exponentially every year, and by the 37th year of Konoha it had reached 20,000!

This number of students has far exceeded that of Konoha Headquarters, and the reason why it was able to catch up so quickly was because Rope Tree controlled the tax revenue of the entire Nishikawa region, which was many times higher than Konoha's income!

This is the reason why the shogunate has been investing most of its funds in local construction in recent years, otherwise the gap between the two will only be even greater! It can be seen that most of the wealth of the entire Fire Country is in the hands of the daimyo government and ordinary merchants, and Konoha and the Konoha consortium account for a very small share.

However, Rope Tree's plan to frantically buy resources to train ninjas soon hit a bottleneck!

It turns out that although the ninja school does not have a big threshold for cultivating ninjas, it also needs a complete set of resources, such as ninja tools, scrolls, food, medicine, etc.

Common ninja tools such as kunai and shuriken can be manufactured in large quantities with Nishikawa's current industrial capacity, and the creation of this cold weapon is very simple, and the steel consumed is less than one-ten-thousandth of Nishikawa's output, and the ninja tools that cannot be mass-produced by modern industries such as detonation charms, chakra test papers, and seal scrolls are originally relatively high-end ninja tools, and ordinary ninja school students will not even use them after graduation, so there is not much problem in ninja tools.

And food and medicine are the biggest problems restricting the expansion of the ninja school! The first requirement for becoming a ninja is to have chakra, and to extract chakra requires both physical energy and mental power.

Generally speaking, the descendants of ninjas due to genetic reasons, after birth, both physical fitness and mental strength are far superior to civilians in nature, and the stronger the bloodline, the higher the talent of the offspring, like Konoha Village due to the selfless dedication of the Thousand Hands Clan, so there are endless geniuses among the descendants, so there are many civilians who can easily refine Chakra from an early age, and ninjas from the ninja family are even more relaxed.

However, such talented people are a minority after all, and the qualifications of the vast majority of civilians are not up to the standard of refining chakra.

The mental requirements are very low, as long as you are not mentally handicapped, you can basically meet the basic requirements, and the important thing is the physical fitness requirements! As long as they can extract chakra people, even children of a few years old are one or two times higher than ordinary adults, and this gap will get bigger and bigger as they get older, which is the main reason why ninjas are regarded as outliers by ordinary people.

Fortunately, the rules of the Hokage world are relatively relaxed, unlike those fantasy immortals that Rope Tree watched in his previous life, they are as rigid as they are, and they can't cultivate without corresponding talent qualifications anyway.

With enough food and medicine resources here, plus a certain amount of exercise, as long as you start cultivating from a young age, most people can reach the standard of cultivation, and all of them are qualified to cultivate chakra.

Ninja is very similar to martial arts in the setting, everyone has the opportunity to practice, but the final achievement depends on their talent and the resources they have.

Therefore, food and medicine are indispensable materials for the training of ninjas in ninja schools, and even formal ninjas can use these two materials to promote cultivation.

Chakra's cultivation requires a lot of body energy, so ninjas need to consume at least ten or even a hundred times more nutrients than ordinary people every day!

If it is a formal ninja who has cultivated chakra, he only needs to pay attention to his diet and eat more high-energy meat food, which can basically meet his daily consumption, but ordinary teenagers who have not refined chakra have far less ability to digest and absorb food than the former, so they must be assisted by medicine during this period.

With the developed agricultural level of Xichuan, there will be no shortage of food, and there will be enough chickens, ducks, cattle and sheep every day!

However, in terms of medicines, it is not so easy, some drugs that assist chakra cultivation can only grow in a specific environment, and the efficacy of wild drugs is better, the effect of artificially cultivated drugs is poor, and more importantly, the effect of drugs is in demand for years, and it takes at least five years for artificially cultivated drugs to be used!

Coupled with the special requirements of medicine for the environment, it is far more difficult to grow than food, and the investment cycle is longer, so few people in the ninja world are willing to cultivate medicine.

Especially in the Land of Fire, the environment is more suitable for growing food, so the medicine used by ninjas is basically imported.

In the past, the Land of Wind and the Land of Thunder had a good environment and scarce arable land, so they cultivated a large number of herbs in the country and exported them to Konoha in order to make a good profit from them.

However, since the Second Ninja World War, the two countries have realized the importance of food, so they would rather develop agriculture at a loss, which has led to a significant reduction in the production of herbs in the ninja world.

And after this war, all the countries of the ninja have suffered heavy losses, and in order to recover as soon as possible, they are stepping up the training of the new generation of ninjas, so after the Nishikawa Ninja School began to expand a large number of students, the price of the drug has risen sharply and is now ten times the original, and there is no market!

After almost all the drugs that were purchased were acquired, Xichuan's ninja school expansion plan fell into a bottleneck!

Originally, Rope Tree also designed a series of policies to open branch schools in various cities in Xichuan, preparing to take advantage of the rapid formation of ninja training, and train all the new generations in the entire Western Capital region to become ninjas, so that when this generation grows up, the entire Western Territory is a ninja country, and there is a foundation for the establishment of ninja civilization.

Rope Tree had long expected that he would encounter a series of difficulties in this process, but he didn't expect that the plan had just started to improve, and he was stuck in the drug resources.

Rope Tree, who had previously won a great victory in the second ninja world war through economic strategy, was hindered by the strategy he had set, which was really unpleasant for the cycle of karma.

Rope trees have begun to encourage farmers in Xichuan and Xilin to grow drugs artificially, and have introduced a lot of support and preferential policies, but these drugs will take at least five years to use, and in order to ensure the healthy development of agriculture in the two places, the area invested in drug cultivation cannot be too much, so the problem cannot be solved from the basics.

In desperation, the Rope Tree can only hope for Goldfinger, ready to rely on the Wish Power system to exchange for a perfect solution.
