Naruto learns Kai and God ki
Naruto in the scroll of sealing learned how to use kai and god kai. He learned that in order to use kai like chakra you need to mediate and channel it through your body. He then started doing push ups and sit ups every day and mediate and unlock his kia. He picked up books and read it day and night. He was working hard learning more combat training and learning from gai about how to fight and sparring against lee. He became calmer in battle. Also became more serious and not seek attention. Learning the kame sennin and learning demon sealing and other ways of controlling his kai. He even learned how to use kai balls and learn the kamehameha. He learned how to charge up his kai to the max and learned to jump in the air. He also used his kia to learn other ancient fighting styles. He then had a team exercise about teamwork. He knew that sakura and sasuke won't work with him he also knew that sasuke arrogance will likely get them killed and sakura fangirl ness will cost them lives.
Naruto like lee wears weights. He wears lots because his clothes are weighted and has weights that are half what lee wears. Also using kai is more potent than chakra. Naruto uses the rapid speed technique to get behind him and kakashi blocks his surprise attack. Then naruto left and said we can't pass. Kakashi said oh why is that. He said emo and inky won't work with me and the whole point of it is teamwork. He then leans down on a tree and mediates his is strong enough that he starts to elevate and rocks start to floats he starts to have a time controlling his kai using the same thing that happened in dragon ball super during the tournament of power against jiren. Naruto then went home and they wasted their time in these teamwork exercise \s and d rank mission.
He hates his time wasted because it takes away from his training. He also learned how to use his kai as a weapon. Naruto has come along way and has bulked up gotten a lot more muscle and gain two new katana and placed them on the side he also gained a new serious look and keeps calm under pressure. He is totally changed and looks badass
