The Void Trunk: Saving the Doomed Alpha

A bankrupt modern heiress accidentally discovers that a mysterious wooden box lets her deliver water, modern miracle medicine, and heavy firepower to a desperate otherworldly wolf clan — she's not only worshipped as the "Moon Goddess" who saves the world, but also uses the chests of gold and jewels she gets in return to strike it rich in the modern world, crushing the scumbag and the mafia alike — a cross-temporal, two-way rise to power on both sides of the box.
