Reincarnated and trying to open the shop !

One day I a student from Shangzhou High got reincarnated as a young master of the Alin clan and after a few days, I figured out some things. My name is Allen I have wonderful golden hair and blue eyes and I have gotten a system that wants me to open a shop. "This is stupid why do I have to open a shop when I can't even cultivate what happens if someone tries to rob me? " I thought to myself.

[System will handle any danger that comes towards the host shop]

A robotic voice in my head said. "OK fine I will try to open a shop wait what shop do I even open? I was very confused as the system just told me to open one giving me no information.

[System will tell you after you get a building]

OK, then I said to myself as I rang a bell to call one of my servants. "Yes young master? " a man who looked to be 20 said "I need a building suitable for a store," I said "Right away sir. " as he dashed off. After a couple of hours, I got this building it was about the size of a normal house and it seemed ok to use. System what do I do now?
