My Host Is an Alchemist, but There's Something Wrong with Her Head

【One heroine + alchemist + System + comedy + white-haired master + villain’s comeback + invincible (If you prefer more everyday-life plots, try reading from chapter 56 onward…)】 After finishing with its previous Host, the System successfully transferred to the transmigration-into-a-book bureau. As it turned out, its very first assignment was an alchemist from the same world as its previous Host. As an April Fools’ prank, after messing with its previous Host, the System picked up Tao He and left. Tao He had been sent over by the world’s guardian, who was sick of her constantly causing trouble. Tao He’s mission was to play the villain in a book and make a successful comeback. But… The System discovered that Tao He might be an alchemist, but she also had something wrong with her head… She pulled out the superb fire spirit root from her starter pack, then swapped it for various low-grade spirit roots and pulled those out one by one, all for the sake of studying spirit roots. She got her hands on all kinds of precious spiritual treasures that enhanced mental power, just so she could make a cup of coffee to stay awake. She took in a pure, naturally airheaded, white-haired little girl as her master, all so she could raise her into a wife… Wait! Why does this plot about raising a white-haired little girl feel so familiar?!
