Naruto defeated JiNing in the test of patience. In episode 5 1, Naruto draws lots to start fighting JiNing KO and episode 60 until 62 and 63. One more thing, ZZ KO orochimaru started fighting in 333, and orochimaru died in 334. The cartoon is not clear. U is not dead in the animation. If you want cartoons, you can go to the Post Bar in Huo Ying. There are cartoons in the boutique area.
KKX died fighting PN. Later, Naruto touched PN with his mouth, and then the body of PN revived all the people who were killed with unique skills, and of course KKX!
