In Harry Potter AU with a system (Myriad Realms Shop owner) HPMRS

Ten years have passed since my rebirth in the United Kingdom in 1981.

Initially, I thought I would use my future knowledge to become rich after being reborn in the past, achieving financial freedom before turning 30.

But on my 11th birthday, within my mind emerged a ‘ding’ sound.

“Myriad Realms Store has been activated"

"store owner, please accept the first task.”

Apparently, I was stepping into entirely new and unknown future.

However, what the hell is with this Hogwarts Acceptance Letter in my mailbox?（°△°—）

And what the hell is this?
