In the twentieth year of Konoha, Lin Chuan transmigrates and becomes an orphan at the Konoha Orphanage, the same age as the Sannin.
After discovering that he can earn rewards by signing in at famous locations, around notable people, and during important events, Lin Chuan decides to keep a low profile in Konoha and quietly sign in.
[Sign in with Tsunade: Reward, Sage Body (greatly increases vitality, enhances strength, repairs...)]
[Sign in at Hokage Rock: “A Complete Guide to the Will of Fire”] (Three years of practice exams, five years to become Hokage; full marks in Will of Fire.)
[Sign in with Hiruzen Sarutobi: Reward, a talent for teaching ninjutsu and all five chakra natures]
[Sign in with Orochimaru: Reward, top-tier research talent]
Lin Chuan keeps secretly growing stronger until he is powerful enough to set his sights on the lofty Otsutsuki.
Thus, during the Second Shinobi World War, he makes a name for himself with his swordsmanship, defeats Hanzo, and earns the Land of Iron’s distant reverence as the Sword Saint. He saves the White Fang, intimidates the shinobi world, establishes a secret organization, gathers the orphans overlooked in the original story, develops Senjutsu for humanity, spreads improved taijutsu, and prepares for the day humanity must resist the Otsutsuki.
