In the eyes of the people of the Shui Wuyue clan, this is an equivalent exchange.

There are gains and losses, gaining great strength, but also losing almost all of the remaining lives.

But in reality, although the samurai gained great strength, they were completely unable to use it to their advantage. Of all the samurai who had achieved initial success, almost all of them were sent here and used in this mission, except for a few who were re-sent to the secret prison of the Shui Wuyue clan.

Most of these samurai were originally just low-level samurai, and such people were more or less in the land of water. Therefore, when the Shui Wuyue clan captured the experimental subjects, they only arrested a few people in each place, which did not let outsiders feel that something was wrong, and ensured the privacy and safety of the research.

However, the compromise on the quality of the test results in a slower progress.

The reason why these people were sent to carry out the mission was actually to show that they had no possibility of improvement, and could only be used as cannon fodder like disposable consumables.

However, in the eyes of Shui Wuyue Ryohei, the combat effectiveness of these people is already quite impressive.

Although some people lose their minds, although it is difficult to control, although there is a risk of backlash...... However, almost all of these thirty people can be compared to the middle ninja who has undergone rigorous training and has been promoted through the orthodox ninja cultivation system in terms of combat effectiveness.

In other words, just from the calculation of combat power, Shui Wuyue Ryohei has at least thirty middle ninjas under his command this time!

This is an extremely exaggerated figure.

Because ninjas pursue absolute elitism in their way of thinking and acting, and they fight with people all year round, simple administrative ninjas are actually very rare in the huge ninja group.

In other words, the level of ninja such as "upper ninja, middle ninja, and lower ninja" generally refers not only to the administrative level, but also to whether the strength is strong or not. And the gap between the different levels of ninjas can be said to be very different, the middle ninja can easily solve the lower ninja several times their own number, and the upper ninja also has a similar crushing strength advantage for the middle ninja.

Not only in terms of strength and administrative rank, but at the same time, the middle ninja often served as the commander of a small unit, while the upper ninja was able to command a campaign independently. This also means that ninjas of different levels also have different levels of intelligence gathering, analysis, battle deduction, mission planning and so on.

Therefore, generally speaking, it is very difficult for a low-level ninja to command a high-level ninja among ninjas. Because in the ninja promotion system, the evaluation of whether a ninja can become a higher-level ninja is not only based on simple combat ability, but also on the level of knowledge, although most of this examination is only based on metaphysical aspects.

The structure of the ninja group can be roughly seen as a pyramid with an extremely large grassroots and a sharper and sharper the higher it goes.

In fact, most ninjas spend their entire lives as a shinobi. Among them, only a very small number of people can become a middle ninja, and then enter the command system among ninjas. And in the average small family, the strongest in the family is the middle ninja level. If there is no mid-ninja combat power in the family, it will no longer be a ninja family by default. Of course, if the family has any secret art inheritance or the like, it can still be considered a family, but once the family doesn't even have a middle ninja, it is naturally difficult to keep the secret art or something, so such situations are generally rare.

And if you want to become a middle ninja, you don't just rely on your own efforts.

No matter what village you are in, the ninjutsu of the upper ninja level is strictly controlled and spread. Ninjas who were born in the ninja clan can say that after so many years of family inheritance, they can naturally accumulate some techniques or other types of resources, and they can always help their own ninjas.

But ninjas from civilian backgrounds are much more miserable, and those who can create high-level ninjutsu on their own are actually the only ones in a thousand, and most of them are from large ninja clans. Therefore, in order to obtain a high level of ninjutsu, a ninja from a civilian background must make more sacrifices and perform more dangerous missions before he can have a slight chance of obtaining a high level of ninjutsu from the village.

Of course, after the civilian ninja has obtained the inheritance of advanced techniques, he will naturally not pass it on honestly, and most of them will be passed on to his juniors in the end. And most of these things are manifested in the form of master-apprentice inheritance.

It is precisely because of these reasons that in the early days of the major ninja villages, the ninja generally had an overwhelming advantage over ninjas from civilian origins. This is only for institutional reasons, not to mention, some ninjas themselves have a strong blood inheritance limit, and the advantage over civilian ninjas cannot be calculated.

And the reason why Shui Wuyue Qi attaches so much importance to sword ninja is because although the sword ninja does not have the transaction processing ability of the middle ninja level, its combat effectiveness is real, and it can be "mass manufactured", but the materials are just everywhere, and the number is several times that of the ninja.

Therefore, the reason why Ryohei Mizuki dared to think of waiting for an opportunity to control the situation in Kukawa City just by relying on this batch of "sword ninjas" was because his subordinates were actually in control of an elite combat force that was not too large in number but powerful enough.

Although the Ghost Lantern clan still has a few ninjas inside, there is already a gap in the internal situation, so naturally they will not work together. In the mind of Shui Wuyue Lianghei, this is also one of the key elements of the success of the mission.

The city defense of Kukawa Castle was very lax, and it didn't take long for all these "sword ninjas" to be transferred to the city.

The reason why it is said to be "transfer" is because the mental state of these "sword ninjas" is very unstable, so illusions and drugs are always needed to control them. Therefore, a batch of sword ninjas, in addition to the sword ninja itself, also needs to be equipped with a certain number of medical ninjas and illusion ninjas.

With such a large-scale group, and there are a group of people in an abnormal state, if the ghost lamp clan is changed to take over the city defense, it will definitely not be able to enter the city. It's just that the Ghost Lantern Clan is new to the country after all, and it is difficult to gain the full trust of the monarchs and ministers of the Kawano Kingdom in a short period of time. At the same time, the Ghost Lantern clan is also turbulent inside, and it is naturally difficult to spare energy to establish a good relationship with the high-level leaders of the Kawanokuni.

After entering the city, Ryohei Mizuki immediately sent his ninjas to inquire about the news of the Daimyo of Kawanokuni, preparing to wait for an opportunity to control the Daimyo.

But unexpectedly, as soon as he entered the city, he received news from his subordinates that the ninjas of Yuyin Village had been discovered, and there was a battle with the local garrison of Kawanokuni.

Soon, this news was also presented to the Daimyo's desk through intelligence information from Kawanokuni.

Immediately, the whole city of Kugawa Castle was placed under martial law.
