MTL - My Daughter Was My Sworn Enemy In Past Life - Chapter 20

One day, after five years of living in the shadow of the popular actor—Mo Boyuan, Dr. Jiang suddenly decided that she had enough!

Cheng Xi, a guileless psychiatrist with a heart of gold, who would do anything for her patients. Lu Chenzhou, a frigid businessman who refuses treatment for his emotional detachment.

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.
