Necromancer Academy's Genius Summoner - Chapter 67

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.

Synopsis: Yang Chen, the inheritor of the divine throne of Hades, was separated from his family at a young age and sold to a foreign assassin organization. Enduring the darkest of worlds, he eventually returned to his homeland incognito. Intending to live a low-profile life as a street vendor selling lamb skewers, fate took an unexpected turn when he married a well-known local corporate CEO. Hoping for a quiet existence, he found himself drawn into the role of a guardian knight due to the presence of beautiful women from various walks of life. As he navigates through these connections, his past experiences and former comrades resurface. Inadvertently, he delves into the world of cultivation in China and uncovers the essence of this world.

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.
