I Am a Great Benefactor of Konoha

After time travel, people either rely on gold fingers to level up, or rely on force fights to level up. But why am I so unlucky? I need to do good deeds to level up. If someone defeats the opponent, they can be executed directly, but I have to let them go. You know, I was a complete evil person before. Is this a development of putting down the butcher knife and becoming a Buddha immediately? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
