I'm a Spy at Konoha Academy

Traveling to the world of Naruto, I found that I was late. The timeline was actually a thousand years after the Fourth Ninja War. Konoha Village disappeared and was replaced by Konoha Academy. But because Cheng Qi was sold by his parents, he was forced to come to this academy to be a... Spy? Wait, who is Uzumaki Hikaru, the girl turned into by Uzumaki Naruto's seduction technique and Uchiha Hikari's hairstyle? Who is Uchiha Yue, who has both Sharingan and medical ninjutsu? And Hinata Momoko, why are you leading a ninja dog when you clearly have your Byakugan open! (It can be regarded as a semi-self-created pseudo-sequel academy article of Naruto)
