Naruto: Sign in to Reaper of Souls at the beginning and harvest like crazy

"Ding! Sign in successfully!"
"Ding! Congratulations to the host for getting: Death Scythe!"
"Ding! The third street sign-in was successful!"
"Ding! Congratulations to the host for getting: Mangekyō Sharingan!"
"Ding! Sign in to Hokage's office successfully!"
"Ding! Congratulations to the host for obtaining: unlimited chakra!"

You start with a knife, and your strength depends entirely on signing. ​
You ask me why I don’t practice, because my strength depends entirely on signing in. ​
Travel through time and become the Uchiha clan, and carry a god-level sign-in system. Sign in at the designated place to get rewards.
