The protagonist is driving a Ferrari on the way to collect rent. What? Fighting for world domination? I think too much. I have nothing to do to collect rent. It's so comfortable to pick up girls. If I have no money, I will go to 1950 to find some treasures. By the way, I will bring some documents such as atomic bomb theory to support national defense construction. Not to mention how comfortable I am in my childhood. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
