Transformed into a Little Girl: Becoming the Shadow Sovereign in a Lord's World

[Lord] + [Gender transformation] + [Dark castle] + [Survival] + [Slow burn]

Yun Ling transmigrates to a world where everyone must survive as a Lord, and acquires the Abyssal Ancient Castle, which boasts a versatile range of troop types.

Here, you need gold to create combat units and upgrade buildings,

while oil fields and mines are essential.

She puts her exceptional gaming talent, and military command skills, to good use,

exploiting the strengths of each troop type to crush the other Lords one by one.

"My oil fields and my mines. Don't even think about taking a single one."

"Your Majesty, please spare us."
