Tui is Kakashi's good friend, and Hatake Kakashi's Xia Lingen was given to him by Uchiha Obito. Kakashi's stunt is Tui's signature ninja. Although Uchiha Obito is a villain, he is not evil.
I was very moved by the scene in which Otsuka sacrificed to protect Naruto and Kakashi, and the soul with Otsuka finally helped Class 7 defeat Ye Hui.
There is a classic line in Naruto that is very popular on the Internet. All Naruto fans are familiar with it. It is this sentence, "people who don't cherish their companions are even worse than waste." Although this sentence is extreme, it makes sense.
Many netizens said that the villain also had a famous saying, which was told to Kakashi with soil, because Kakashi didn't intend to save the forest at all. Uchiha Obito is not a person who abides by the rules, but he is better than many positive roles in some aspects.
