Mushroom Poisoning Made Me Adopt a Toy Empress as a Pet

Xie Yan, a broke college student, orders a bag of Yunnan "specialty" mushrooms online. Little does he know that after boiling them into soup and drinking it, he'll kick off a real-life "adventure in the land of the little people"! He transforms into a ten-centimeter-tall being of energy and starts fighting monsters and leveling up in the flower bed outside his dorm. He thinks this is just his golden finger, until he saves a tiny "figurine" person from a swarm of ants. The little person wakes up with [LV???] floating over her head, and the first thing she says is, "Mortal, did you awaken this Emperor?" The next second, seeing that Xie Yan's palm is bigger than she is, the female emperor immediately changes her tune: "Master, I'm hungry. I want food."
