Why did Kyubi no Youko attack Konoha?

Kyubi no Youko opened the seal of the scroll and began to attack Konoha. Lord Mu Zi Jieyuan (an old man in his 200 s, one of the founders of the Dark Department, even three generations are young in front of him. He is the housekeeper of Kakashi family, and Qimu Shuomao's knife is his. The weapons and equipment of the dark department are also based on his knife-digression. According to the entrustment of the four generations, at this time in, the four generations are all waiting for the birth of their son (namely Naruto), and the delivery is Ye He Feibing (female, one of the dark elders, who gave Kakashi a "bosom paradise" as a birthday gift on his 20th birthday). The wife of four generations under one roof is a fortune teller, whose name I forget. Anyway, as soon as a celebrity is born, four generations will drop blood from the palm of their hands into the celebrity's mouth, then launch a move (preparing to seal Kyubi no Youko) and then go to the front.
