[Naruto fanfic + system + Nagato + making up for regrets + not killing Chuuriki + single heroine Konan]
When he opened his eyes, the kunai in Yahiko's hand was still cold.
He traveled through time and became Nagato.
His legs were destroyed, and the Heretic Golem was still beating him to death. Hanzo and Danzo's men had already arrived in the rain, ready to dig out the Rinnegan Eye.
The bound Dawn system is more straightforward: no blood successor is sent, no chakra is sent. If you want to become stronger, save those who would otherwise die and end those wars that would never end.
Therefore, the first thing Nagato did was not to create Pain, but to lead the remnants of Konan and Akatsuki to survive the night.
Kill Hanzo, hold Amegakure, rewrite the night of the Nine-Tails, and protect Uchiha; instead of hunting down the ninchuuriki, the nine tailed beasts must voluntarily hand over their power.
Obito is waiting for him to turn black, Black Zetsu is waiting for him to resurrect Uchiha Madara, and the five great ninja villages are waiting for Akatsuki to become everyone's enemy.
But this time, Nagato didn't accept anyone's script.
He wants to become the Ten-Tails Jinchuuriki, defeat Madara and Otsutsuki, and personally end the war in the ninja world.
When it finally dawns, he will dismiss Xiao Nan and leave with Xiaonan in hand.
