Shocking! My Closet Opens Into a Primeval Forest

[Time Travel + Feel-Good Story + Wild Imagination + Supernatural Powers + Wealthy Older Man] On the first day of her summer vacation at home, Mu Yao sensed something strange. The clothes in her wardrobe kept disappearing for no apparent reason. On the first day, the underwear hanging in the wardrobe vanished. On the second day, her brand-new clothes disappeared too. On the third day, even the hangers were gone. Worse still, she heard repeated banging sounds coming from the wardrobe and thought her house was haunted. Clutching a kitchen knife, she worked up the courage to open it, only to find a primeval forest behind the wardrobe. But it didn't seem like an ordinary forest. Have you ever seen a carpet of mushrooms? A forest of mushrooms taller than people? Strawberries the size of eggs growing on trees? Grapes in all sorts of colors... Everything she saw turned her understanding of the world upside down. Even more unbelievably, at the bottom of a lake deep in the forest, she found a black dragon that had been sealed for a hundred years, along with a mysterious little plant capable of anything. Only then did she realize she had somehow arrived in a world of immortal cultivation and fantasy. Later, she joined the Bureau of Supernatural Abilities and encountered all kinds of fantastical and bizarre things: exotic beasts, spirit herbs, inscriptions, magical artifacts... The mystery of her own origins gradually came to light as well. From then on, a woman, a dragon, and a plant began their legendary adventures across two worlds. Wherever they went, they left nothing behind, not even a single hair. [The heroine is a genius, loves showing off, fools people with her looks, and is vain and thick-skinned] [Set in the 21st century at first, then shifts to a fantasy world] [Warning: There is a male lead, and the romance can be a little awkward. Don't force yourself to keep reading if it's not for you.]
