Reincarnated to Trade Spouses

In her past life, Wendy devoted everything to support her husband, only to be brutally betrayed and killed by him and her green-tea stepsister at death's door! Reborn with memories of blood and tears, she decisively tears up the engagement, kicks the selfish scumbag to her stepsister, and turns to marry the Imperial Knight Commander—rumored to be possessed by an abyssal demon, "lethal upon touch"! Everyone mocks her for rushing to her death, unaware that she has unexpectedly awakened a lost ancient magical bloodline, becoming the only person in the entire empire who can soothe this "bloodthirsty God of War"! When the scumbag and stepsister are ruined by their own greed and kneel begging for mercy, the once-destitute little tailor has long since, under the extreme devotion of her wife-protecting maniac husband, transformed into the Chief Enchanter standing at the pinnacle of power! "In this second life, you're not even worthy of looking up at me!"
