[Zhuoying] After the Village Was Built, I Eloped with My Mortal Enemy.

As an aborigine, I was suddenly entangled by something called "system"... After diligently improving my strength with the help of the system, I was told: The world has been pierced through a sieve! Including but not limited to myself and the Uchihas of parallel time and space... Looking at the Nichirin Sword in my hand, I, who is said to be the reincarnation of someone's soul, decided to save the world! (?) Original protagonist x original CP traditional Senju paired with Uchiha The article I wrote in a notebook three years ago, typed and uploaded by hand, is also a way of recalling my beautiful youth! The protagonist is the reincarnation of Enzhu's soul clone, but he doesn't have many connections with the original demon slayer. Please read it as an independent person. Intention: Persistence will definitely lead to results
