Lord of Ten Thousand Beasts: Inheriting a God-Tier Gacha Machine from the Start

[Transmigration] [Gacha] [Beast Taming] [Worldbuilding] [A Growth Story] [No Romance] Yun Wu transmigrates to another world and is delighted to inherit the family estate and become a lord right away. The bad news is that the territory is on the verge of bankruptcy! With no other choice, Yun Wu scours the lands, hoping to find something valuable. Who would have guessed she would discover something in the basement... Yun Wu looks over the machine again: the coin slot, the lever, the display window, the dispensing hatch. Its design, that familiar feeling... An absurd thought strikes her like lightning! This thing... why does it look so much like the gacha machines in the arcade downstairs from her old office? You know, the kind where you put in a coin, turn the lever, and a plastic egg rolls out of the bottom with a random little toy inside! P.S. The heroine is an ordinary person who grows over time, not invincible from the start.
