[Decisive killing + system + cool writing + assassination + invincibility]
Traveling through the world of Naruto, Jiang Shuai obtained the "Assassination of Rebel Ninja System". As long as he kills the traitor in Naruto, he can get rewards.
The good news is that he signed the Mangekyo Sharingan at the beginning. The bad news is that his name in this life is Uchiha Jiang Shuai, which happened to be a few days before Uchiha Itachi massacred the entire clan.
When he returned to his family after completing the system mission, only Sasuke survived among the family.
They happened to collide with Itachi and Obito and had to fight.
Obito took a fancy to his Mangekyou Sharingan and intended to recruit him into the "Akatsuki" organization, but the system issued a killing mission.
Kill "Scorpion" to obtain the Ninjutsu Controlled Puppet.
Kill "Deidara" to obtain all earth attribute ninjutsu.
Kill "Nagato" to get the Samsara Sharingan.
Kill "Madara" to gain the power of six paths.
Jiang Shuai disguised himself so well that no one noticed that he was the person who had been killing the Xiao organization.
During the Fourth World War, facing the ninja coalition, Hei Jue succeeded in saving his mother, and Jiang Shuai stopped pretending.
"Kaguya, I'm tired, you can pose yourself."
