Checking in to the Heavens: a Check-In System Starting from Konoha

My name is Gu Nanzhi, an extremely ordinary anime geek. The day I died suddenly during overtime, I thought I was gone, but when I opened my eyes, Naruto was smiling at me with a Fuma Shuriken. There is an extra system in my mind - the All Heavens Sign-in System. The rules are simple: sign in once a day and complete plot tasks to get rewards. The rewards can be chakra, devil fruits, Zanpakutō, or even... The life of a certain villain. For others, traveling through time is hard, fighting monsters and leveling up, but for me, I get stronger just by signing in. Konoha, Pirates, Soul Society, dungeons passed by one by one. While Uchiha Obito was still struggling with how to deceive the whole world, I had already received the Rinnegan as a daily sign-in reward three times. ——The protagonist of this world, Halo, from today on, his surname is Gu.
