Transmigrated into the world of Naruto, without the instant awakening of 999-tomoe Sharingan, but with a universal deduction system. Initially, it was thought that the system could only be used to become a scholar. But when the system was accidentally updated, everything changed. Sarutobi Hiruzen, who knew the entire plot, imparted all his ninjutsu in the deduction space. Orochimaru, who gained various biological knowledge, became the best experimental assistant in the deduction space. Sasori, who gained a lot of mechanical design knowledge, became the best mechanical designer in the deduction space. ... Note: This book is not an infinite cross-dimensional travel story, but a star-crossing story, aiming to counterattack the Otsutsuki clan. (The focus is on the Naruto world, other planets will be written depending on the results, if the results are poor, then it will not be written)
