Primordial Harem System - Chapter 7: Surpassing The Limits

One day, the majority of humanity had a collective thought.

‘I wish the world would just collapse.’

And then, that wish came true.

Whoever refuses to accept, come fight!

Waking up in the body of a 6-year-old boy a few years before Cintra is destroyed, Madara receives a system that gives him the ability to gain the powers of Uchiha Madara.[The peak of Uchiha Madara's system is before he becomes the ten-tails jinchuuriki.]The system's percentage does not stop Madara's power, but rather the system's release. After all, I don't want to see a character who goes around killing everyone from the beginning of the story.
