Naruto: While Others Weave Hand Signs, I Cultivate Immortality!

Chen Chuan, a goofball from the 21st century, accidentally transmigrated to the Hokage world and acquired a System that lets him utterly crush Hokage characters. While everyone else is forming hand seals, I'm cultivating immortality. As long as I act cool, I can beat them all. Can I gain experience just by beating up characters from the Hokage world? From then on, the world of Hokage changed... “Naruto, don't run... Come on, be a good boy and let me smack you once. Just a light smack.” “Kaguya?” “Hand it over!” When Pain attacked Konoha, a handsome young man rushed out and shouted: “Everyone, stand back! Leave this to me!”
