The Butterfly Effect by loltales

One day gates opened which connected Earth to Otherworlds. With it some became saturated with mana and developed abilities. They climbed the gates to the upper worlds too see the realms that were once myths. And I, a person with negative mana is stuck here, in a outdated town managing a nursery in my grandma's backyard. Two years later and I am same as before, until my world is flipped upside down with a knife tearing through my stomach and blue butterflies bursting out. Now, how do you expect a teen with minor entomophobia to deal with this? *The MC is a woman, I chose this category because webnovel doesn't have a category for female MC in action fantasy.
