Senju Hashirama used the self-healing function of cells at the cost of his life, which led to his early death.
The ability of cells between columns in the play is very BUG, which can not only start the escape of wood to give users a strong offensive ability, but also use the ability of cells to accelerate disintegration to repair the physical injuries suffered by warriors in the process of performing various daily tasks.
But this ability is still flawed, that is, accelerating the speed of cell division is also shortening the life span of users, because the frequency of cell separation in the body is actually certain. Before the establishment of Muye Village, Zhi Zhu took part in many battles, not only with Neiguang, but also when performing tasks.
Therefore, Senju Hashirama used intercellular cells too frequently to heal his body, which endangered his life. In fact, the samurai who can heal themselves without printing in the plot didn't live long, while Ootutuki Hagoromo could heal himself at any time and anywhere, and eventually he could not escape the fate of death.
Senju Hashirama has a strong repair ability, but the use of this ability is obtained by shortening its life span and accelerating the frequency of cell division. Before the establishment of Muye Village in Senju Hashirama, there were many stages of wars, which consumed too much life expectancy and led to the early death of Senju Hashirama.
Many people may be curious as to why Senju Hashirama's repair ability has been so good. In fact, there are no intercellular cells in Gang Shou, so the loss of life after reconstruction by forbearance method is not as obvious as that in Senju Hashirama, and frankly speaking, Gang Shou does not use this method frequently, so the loss of life is not as obvious as that in Senju Hashirama.
Senju Hashirama's sudden death was killed by the plot, and the friendship between the five ninja villages that didn't die between the columns won't be shaken, and the subsequent plot won't be smooth.
Although judging from the overall plot development trend of Huo Ying, it seems that the reason for the disagreement between Uchihiro Shoko Asahara and Senju Hashirama is black tricks, in fact, the inducing factor to promote the plot development trend is the rights dispute cases between countries.
As we all know, if Senju Hashirama lives too long, the country of fire to which Muye Village belongs has obvious advantages (the title of Ninja God in Senju Hashirama is not for nothing), which also causes other countries to be afraid of getting rid of their previous relative friendship and entering a state of war.
Therefore, the death between the pillars is also a specialty of various rights disputes. That is to say, if Senju Hashirama didn't die, there would be no later Naruto, and the turmoil in the ninja world would not be as impressive as in the plot.
Therefore, personally, I think that Senju Hashirama's death is the need of the plot (similar to the situation of Feng Shui Gate), and it is to give sufficient indoor space to the development trend of the plot of The First Hero. The market competition and space competition in the middle of Ninja Village will not be so fierce, and the development standards of Naruto will also change a lot.
Senju Hashirama's death should be an external standard for the constant disputes and disputes in the ninja world. Without the essence of pursuing perfect profit maximization in all fields, the suppression of absolute power will be exposed.
Finally, to sum up, I personally think there are only two reasons for the death between columns. One is the side effect of the use of cells between columns (accelerating cell division and healing at the expense of shortening life span), and the other is the need of the plot. There will be less commotion between columns. Please forgive me if the analysis is not in place.
