Li Bai had once killed a chivalrous man in the alley, who was also a street hooligan. He once killed several people with his own hands. He and his friends went from Jingzhou to Yangzhou. On the way, they lost their power. When they returned to the boat, it was very hot. The lost friend was defeated and his bones were collected on the river road. Li Bai advocated chivalrous men, and swordsmanship was his other lifelong love. However, there was no clear answer to the question of Li Bai killing Meng Haoran. Therefore, it was impossible to determine who Li Bai had killed.

It could be a random civilian. This would show Naruto the impact of the ninja world's violence on ordinary people, making him more determined to protect the innocent.
Sasuke could turn into the main antagonist if Naruto is killed. Their bond was so strong, and Naruto's death might break Sasuke completely, leading him to go against everything Naruto stood for and become a new threat.
Naruto did not die in the last episode of Naruto. The Akatsuki member was killed by Sasuke. The recommendations are not related to the question, but I like light novels very much, so I recommend the following books: I'm a Power Bank in Koba, which allows you to view the ninja world from a light-hearted and humorous perspective; Because the style of Naruto in Class 7 has collapsed, which is a book full of jokes and is very suitable for relaxing; I've become a whirlpool naruko, which is warm and sweet, and is very suitable for healing readers; The Samsara of the Akatsuki Organization is a very interesting doujinshi novel with an interesting story. I hope you like my recommendation. Muah ~
