Becoming the Earl of Mount Kimi Depends Entirely on the Help of the State

My dad is a potion master and sighs at the success rate every day. My brother is a military commander and he doesn't dare to fight back when someone beats him up. My sister is responsible for good looks, and she recently received crazy private messages from a certain aristocratic young man. I am Colin, a time traveler picked up by them. The whole family thought I was a little loser who only needed to be loved and patted on the head. But they don't know that as a qualified time traveler, the moment I open my golden finger, there are 1.4 Billion parties standing behind me.
