I Became a Cat-Eared Little Princess in a Matriarchal World

Long Mao, once a street thug, transmigrates into a cat-eared little princess and discovers that she has become a captive of the Demon Realm's queen. What?! In this other world, cuteness is justice?! Wait a minute, Long Mao's survival strategy in her previous life was to be a tough guy! …And now she even has a seemingly useless, adorable System that can actually conquer the three realms?! The former thug can only act cute if she wants to stay alive. [A generally lighthearted and fun everyday life in another world (maybe), mostly goofy cuteness, with a fantastical adventure woven in.] [A serious blurb that may have little to do with the actual story] The captured princess of a distant land passes through an age of thorns and roses, twin blades roaring like dragons… She forges the Source Arts of the Five and Two Extremes and sings the Seven Original Sins, bringing art, thought, substitution, form, and life to their utmost heights. The secrets of taking life, and the means of seizing and giving, unfold in the mortal world. Within the realm, she devours mountains and rivers, treads through hell, cuts down thorns, destroys the demonic sects, and restores the light of her ancestors. Rampant sin lurks beneath the skin, and the horns of the demon hunt sound across the burning wilderness. With the Source as her starting point, she rises from the Great Wasteland.
