I'm Max Level, Yet Just Biding My Time in a Xianxia World with a Supernatural Horror Aesthetic

I transmigrated, and being born max level is all well and good, but what the heck is going on with my willowy mother beating the tar out of my burly father? In this world, women lead armies into battle while men stay home to support their wives and raise their children? Girls are expected to study hard, cultivate, and rise to prominence, while boys should be pretty and refined, skilled in music, strategy, calligraphy, and painting, so they can marry into a good family? Wait, what about the water ghost on the roof beam, the private school where the sound of reading still rings out after it burned down, the age-old rule against traveling at night, and the "sage" who loves to eat human ears? A xianxia horror story? Gu Jiu thinks there's something wrong with this world, but all he wants to do is freeload and wait to die. "Isn't life just a story about eating, drinking, and sleeping while staying at the peak of your game?" So said Gu Jiu, the laziest sage in history, in some year, in some month.
