My Useless Superpower Is the Domain of Ice

[Complete] In the age of supernatural abilities, the Interstellar Alliance prizes strength. Every citizen awakens an ability upon turning fifteen. Xu Jintang awakened a useless ability: Domain Slowdown. Domain-type abilities are rare, but the slowing effect is so underwhelming that it can only be used for support. So when Xu Jintang entered military academy, she was assigned to the support class. Hoping to improve her situation, she trained hard every day and quietly worked to grow stronger. No one knew that a mysterious creature had been living inside Xu Jintang all along. Under its influence, her supposedly supportive ability began evolving in an incredible direction. After training for a while, Xu Jintang stared at a little white mouse that had just entered her domain and been frozen solid, lost in thought. Later, when demonic beasts attacked the city, tens of thousands of them surrounded the entire main city. The authorities issued an emergency notice, calling on all kinds of ability users to hurry to the battlefield and defend the city. That night, a group of low-level demonic beasts launched a sneak attack, slipping into Xu Jintang's logistics support unit to catch them off guard. Under the moonlight, Xu Jintang stood beside an old pagoda tree, sucking on a lollipop. She snapped her fingers. Within her domain, everything is frozen solid. A blizzard descended. Frigid winds swept through the area, and within moments, everything within several miles had turned into a frozen world. [The protagonist has an absurdly powerful golden finger and is a total badass, though she occasionally has bouts of chuunibyou. There is a male lead who appears later. The protagonist isn't a lone wolf and has teammates. The story has a touch of ensemble cast.] ---Coming Soon--- The Ace Assistant's Tycoon Investor System.
