The Peerless Beauty of the Useless Fifth Young Lady

And it's a world she never knew existed—fighting with magic and battling beasts? What on earth is all this? However... since she has arrived, she's going to live life to the fullest! Moves that take others months to learn, she masters in days; ranks that take others years to reach the third stage, she achieves in two days; while others produce two or three pills per alchemy session, she produces an entire furnace at once; while others struggle to defeat beasts to form contracts, the Saint Beasts and Divine Beasts are sitting in rows waiting for her to contract them. Damn it, what kind of treatment is this? She was born purely to spite people. "Hey, have I stumbled upon a treasure?" A certain man stared intently at the breathtakingly beautiful girl before him. "That's right, and this treasure of mine isn't for just anyone to pick up." She only showed her feminine side before him, and he only removed his cold mask before her, his heart devoted solely to her. She laughed and played, acting like a "pig to eat the tiger" as she traveled through various realms and collected all sorts of treasures, while he simply protected her from behind with a smile. The girl once asked, "I have so many treasures, don't you want them?" The man said dotingly, "Are you mine?" The girl nodded, "Yes." "Then you are mine, and your treasures are mine too." When the black-bellied her meets the even more black-bellied him, it is nothing short of a disaster for all living beings~~
