Thirty Years of Sign-Ins in Konoha

In Year 20 of Konoha, Lin Chuan transmigrates into an orphan at the Konoha Orphanage, in the same generation as the Legendary Sannin. After discovering he can earn rewards by signing in at famous locations, around important people, and during major events, Lin Chuan decides to keep a low profile and quietly sign in throughout Konoha. 【Sign in with Tsunade: Reward, Sage Body (greatly boosts vitality, increases strength, restores...)】 【Sign in at Hokage Rock: 《The Complete Guide to the Will of Fire》】 (Three years of practice exams, five years to become Hokage, full marks in the Will of Fire course.) 【Sign in with Hiruzen Sarutobi: Reward, talent for teaching ninjutsu and all five chakra natures】 【Sign in with Orochimaru: Reward, top-tier research talent】 Lin Chuan keeps secretly building up his strength until he is powerful enough, then turns his gaze toward the mighty Otsutsuki. Thus, during the Second Shinobi World War, his swordsmanship shakes the shinobi world. He defeats Hanzo, earns the Land of Iron's reverence as the Sword Saint, saves White Fang, and strikes fear into the shinobi world. He establishes a secret organization, gathers the orphans overlooked in the original story, develops Senjutsu for humanity, spreads improved taijutsu, and prepares for humanity's future fight against the Otsutsuki.
