The author's book is still the book of items, right? But according to the impression in my mind, orochimaru won the title of Konoha in the battle with Gang Shou, Jiraiya and Shimada Hanzo, a mountain pepper fish. After the battle of life and death, he felt that his strength was far from the other side, so he devoted himself to studying the forbidden art of the immortal serpent ... When doing human experiments, he was discovered by the three generations of Master, fled from Konoha and joined the criminal group Xiao ... In order to avoid Xiao, he sneaked into the ferret and was chased by Xiao because of the information he wanted. That is, in the first film, orochimaru founded Ninja Village to attack Konoha for the purpose of getting sharingan in Sasuke Uchiha; He killed my father, who lived under the same roof for four generations, and fought a life-and-death battle with the ape to assassinate Master.
