In the anime, Ninji, as a ninja, shows a strength that stands out among ordinary ninjas.

Although his skills could not be compared with Naruto and Sasuke, the two peers who had opened the six hangings, there was no way to fight against Kakashi who had taken the hanging from the belt, or pick up a few moves under Kai who had opened eight doors.
But among the 12 small strong, Ning Ci's level can be said to be mid-to-high, which is a very reliable output, and the IQ has always been online.
Unfortunately, in the 4th Ninja War, Kishimoto's plot kill made him retire.
Instead, Kai, who seemed to be dying at the time, struggled with Naruto's help.
So, Ming Ming Ningji can dodge, why can't Kishimoto let him survive?

1. The contradiction hidden behind Kai is far less sharp than Ning Ci's
Looking at the famous ninjas that Kishimoto killed in the Four Wars, we can see that many of them are not good for him to kill.
For example, if Nara Shikaku, Yamanaka Kaiichi, and Aoi are alive, the scenes of Shikamaru and Ino's imminent appointment will be more difficult to arrange, and the situation of the high-level control field on the water shadow side will also change greatly.
Another example is the scum of the tu brother who was crushed into slag in the battle with Hui Ye Ji, if he survives, it is one thing that other people have any knots in their hearts, and it is difficult for Kakashi to reduce his guilt. This man will live until after four battles, and Uncle Snake, Immortal Pocket, and Sasuke will all be affected to varying degrees.
And Ning Ji, obviously, also carries with him a contradiction that is difficult for Kishimoto to deal with.
Although There are also many contradictions in Kai's body, many of them have long ceased to be sharp.
Ever since he had become so powerful through the Eight Doors, few people would care to continue to bully him as before. At the same time that everyone else's illusion was in full development, he was in this rank only by physical skills.
And by the time he opened the eight doors and waited for death, he had already reached the peak of being proud of the almighty.
In this case, Kishimoto did not need to face too sharp contradictions if he wanted to "resurrect", and he did not need to have great psychological pressure when doing so.
Ninji's side was different, he was the first person in many years to put the caged bird problem in the sun, and the first person to throw this rotten account in front of the Hyuga clan, Kiba High-rise, Naruto, and Kishimoto.
When this bridge section was first designed, Kishi should have been at an age of enthusiasm. He thought he could resolve the contradiction in the future plot, so he did not hesitate to arrange it.
When Naruto was nearing the end, Kishimoto found that the foreshadowing he had buried in the early stage was about to get out of control, and he still couldn't clean it up.
In this case, it was a very good choice for him to do away with Ning Ci - if Ning Ci did not die, he would die a huge number of brain cells.
2, the problems on Ning Ci's body, he can't solve them through ordinary means
Naruto is a teenage manga, not a dark manga like Jinju, and a lot of things obviously can't be spread out directly in the sun.
Don't look at Naruto's many words with grandiose voices, in fact, many contradictions he can't solve, can only rely on big words to delay time, or simply muddy.
But Ning Ci's problem obviously can't be dragged on so long, and the slime option doesn't seem to be very reliable.
After all, the blood and tears that have been oppressed for so many years are still there, so the lifting will be lifted, not only will the Zong family explode, but the separation is likely to usher in a round of emotional rebound.
In this case, which of the two options is easier for Kishimoto to control by doing the familiar Ningji and letting the Hyuga clan carry out an uncontrollable reform?
If there is no way to solve the problem that was asked, simply solve the problem of the person who asked the question, so that no one will continue to ask questions - but is it possible?
Kishimoto eliminated Ninji and only closed one of the sources that asked the question, while the others continued to ask questions to him, to Naruto in Naruto.
If nothing else, let's say that the reason why the Shimohito 4-man group threw their heads and spilled their blood so much this time was to provide kasumi no Kuni with strategic materials that could not be obtained by formal means between the five major powers, so that it would have more advantages to deal with the disputes brought about by the big powers.
From the side, the current situation of Kasumi No Kuni is also the result of the acquiescence of the top brass of the five ninja villages, and this also includes Naruto, who once liked to speak out the most.
Naruto didn't have the ability to solve the problem of the survival of small individuals like Yu Yin and Kasumi No Kuni, even if he boasted to Payne about haikou; similarly, he didn't have the ability to solve the Hyuga Clan Division, his wrist was not iron-blooded enough, and once he intervened, he didn't know how to die.
The weak eat the strong, and the natural selection.
Although weak people like Ninji and the former Nagato trio look pitiful, the strong can only help some individuals even if they want to help, and there is no way to help them in a large area, otherwise they will not be strong themselves.
The glory of the Hyuga clan and the whole clan is almost always based on the blood and tears of the separated family, and the five major countries can stand firm in the human world, and it is inseparable from factors such as constantly encroaching on the interests of other small countries.
In this case, how dare Kishimoto let people like Payne and Ningji survive and continue to question?
