I Kill Uchiha Shisui with One Slash, and Obito Comes Knocking

Liunian transmigrates into the Naruto world and obtains a god-tier sign-in System. As long as he completes sign-in missions, he can claim rewards.

Aizen Sosuke's template, Mangekyo Sharingan, Hollowfication techniques...

One day, Uchiha Madara invites Liunian to join the Akatsuki, but he never expects what happens next... Liunian kills Sasori of the Red Sand, turns Hidan into a reaper, beats Uchiha Obito to a pulp, and gradually takes his place, seizing control of the Akatsuki.

Only later does Liunian discover that this world contains not only the impure world where the living reside, but also the Pure Land where souls go, as well as the otherworld of the Otsutsuki clan!
