I Traveled Through Time and Became a System, and the Host Turned Out to Be Me.

What! I've traveled through time! It's like I'm not the protagonist! I became the system! The host is... My little girl! ! ! I changed the name of the system to Dad! My childhood friend and I are famous playboys in City B. Our biggest hobby is drinking. That day we staggered out of the bar as usual. We drank too much and fell down on the road. I went to help him, but a large, fully insured truck driving at a high speed came towards me. Bang! When I opened my eyes again, I realized that I had traveled through time! Good news: I traveled through time to enjoy the novel of cultivating immortals. The bad news is that I am not the male protagonist, I have become the cheat system. There is also breaking news, the host is actually my childhood friend. Yoho, after twenty years this piece of shit finally fell into my hands.
