To put it bluntly, in the eyes, only Lin is his recognized relative, and everyone else is a foil. Even in Xiao's organization, many people regard Xiao's organization as their "home". They all have friends or treasure people in Xiao's organization, but these people are just his pawns for Dai Tu.
Tu Tu has been a warm-hearted person since he was a child. From often helping the elderly, it can be seen that many people think that a series of behind-the-scenes mistakes have killed the Watergate couple, but they are not. Only after knowing that Lin killed people to protect the village, he now hates the ninja world and endures this system, so he wants to change the world. At the right moment, Ben mentioned infinite Harle to him. As long as he enters the infinite world, there will be a complete Watergate class and a forest that loves himself. Everything exists, and the ninja world can do as he wishes, so the real world can not care about being killed.
Finally, I saw that Uchiha Obito's brain hole ended the war by himself. When he became Huo Yingran, his face appeared on Huoying Mountain. I laughed till I cried; I laugh because I really think it's funny to make my own fire shadow in this way. Everything in my dream is really the best. I cry because I miss him so much that he can be the protagonist, end the war and let Naruto, I love Luo and Sasuke and other children live a better life. Yahiko, they won't be orphans, ferrets don't have to kill people, they can marry their sisters.
In fact, I think the ending almost made Dayto realize his wish, becoming Huo Ying (though Kakashi), ending the war and being with Kobayashi (Kakashi was too in the way to take him with him).
