Introduction: What is the use of the four generations of bitterness given to Naruto? Seeing the words engraved on it, I understood that this was my father's last love
In the anime Naruto, although the four generations of Naruto died young and could not accompany their child Naruto to grow up, who knows the hard work of being a father? When the four generations chose martyrdom, naruto was left half of the nine-tailed chakra, and although it caused Naruto a lot of trouble, the nine-tailed chakra was a double-edged sword that could protect Naruto even when it made Naruto suffer.

And in the Fourth Ninja War, the fourth generation gave Naruto a gift, a seemingly ordinary kushina, but it can be said that its meaning is more important than the nine tails, that is, the flying thunder god Kuwu written with the sword of benevolence, this weapon has been used by the fourth generation of Naruto. In the early days, Watergate learned to fly the god of thunder, and mastered the second stage of the flying thunder god can use the bitter god to haunt the ghost, so that the enemy can not touch the direction, and even with the strength of one person to contain the thunder shadow and Chirabi, and this time the water gate will give the bitter nothing to Naruto, is it also to let Naruto learn the flying thunder god?
In fact, it is not difficult to see that the flying thunder god Kumu engraved with the sword of forbearance seems to be of little use, Naruto does not use the flying thunder god, so what is the significance of the four generations handing over this bitterness to Naruto? In fact, it is not difficult to see that Watergate has always thought that he owes Naruto, so this weapon is more like a love for children. Although Naruto can't fly Thor, Ku-no is an ordinary weapon around Naruto, but in fact, the fourth generation is also worried about Naruto's safety and wants to teleport to Naruto's side at any time, and Ku-no can be said to be his father's last love.
Although Naruto can't use the Flying Thunder God, the four generations can teleport to the Flying Thunder God Kuzu and guard Naruto. This kind of fatherly love is really great. And the four words engraved on the Flying Thunder God Bitterness, "Sword of Patience", actually have another meaning, that is, to let Naruto learn to be benevolent and be a better Naruto than himself, which is really the last piece of his father's bitter heart. Naruto also deeply understood Watergate's intentions, so he took his father's suffering to the battlefield.
Many people expressed regret that Naruto had inherited his father's spiral pill, but not his flying thunder god, and such a powerful time and space ninjutsu had been abandoned. However, Naruto's learning of the art of teleportation also compensated for the lack of speed.
Although usually the flying thunder god should be mastered by Naruto, after all, it is his father's strongest move, and it should be the son who inherits his father's business, but unfortunately Kishimoto may think that the four generations of the forehead are uniquely portrayed too deeply in the hearts of the people, so Naruto gave up the flying thunder god, and even the second generation of the original creator of the flying thunder god admitted that the speed of the four generations was faster than himself, perhaps this also laid the foundation for the strength of the four generations of flying thunder gods. Sometimes it is not ninjutsu against the sky, but people who use ninjutsu against the sky, such as the fourth generation, who exert the flying thunder god to a situation where even the higher level of time and space ninjutsu god can not escape, and it can only be said that this is the best spokesperson for the flying thunder god.
Although Naruto will not use the Flying Thunder God, but in fact, Naruto's Instantaneous Technique can completely replace the Flying Thunder God, although the Instantaneous Technique is a low-grade version of the Flying Thunder God, but in fact, Naruto can perfectly achieve a speed similar to the Flying Thunder God under the effect of the six blessings, perhaps not as good as the Flying Thunder God at a distance, but the melee combat can be comparable, and this can be proved when Naruto cut off the arm of the Night. It can be understood that the teleportation technique of the medium and long-range Naruto is stronger, while the flying thunder god of the four generations of the long range is stronger.
