Naruto: a New Age

Lin Yu woke up in Konoha Hospital and became a 5-year-old orphan "Yu" who was taken in by Iruka. With the memory of his past life, he mastered the chakra refining technique in three days and drew the map of Konoha and the ninjutsu seal diagram. They used chakra control techniques to form a bond, but were treated coldly by Sasuke. After entering the Ninja School, Lin Yu pointed out errors in the teaching materials and demonstrated optimized transformation techniques, which attracted Kakashi's attention. During the physical fitness test, Naruto was taught how to regulate breathing, and when faced with a challenge, he used the "substitute smoke bomb" to save himself, demonstrating his tactical thinking.
