After Inheriting the Territory, I Have to Give Instructions Every Day

My parents left me and my sister early to travel around the world, leaving me and my sister to depend on each other. I never knew what kind of job my sister had been doing, and even if I asked her, she wouldn't tell me. It wasn't until after I graduated from school that an old man came to me and said: "Master, the lord has inherited this territory to you." "From today on, you are the new lord of this territory!" Only then did I realize that my family was actually the ancestral lord of this land... This novel and its characters are purely fictitious.
