This Lord Follows a Slow-and-Steady Development Path

This is my first attempt at writing, so the story isn't very good, and the ending is rushed. I'm sorry to all the readers who supported me. In his previous life, Lu Hao was an unremarkable nobody. By chance, he transmigrated into the body of a baron and awakened a System, though it was pretty useless. So he had no choice but to keep a low profile and build his strength. But as he kept developing, how did he somehow become invincible? The protagonist cultivates both magic and martial arts, embarking on the path to godhood. If you're not enjoying it, feel free to tear it apart, dear readers, but please don't leave.
