When other people time-travel, they either get hit by cars, commit suicide, etc. How come they come to my place to have a drink and then time-travel? Okay, just travel through time, what about the plug-in? What about the system? The gods guide that! Could it be that just because my time travel routine is wrong, there is nothing left? That's okay, then it's okay for me to use my modern knowledge to become a successful person, but wait, but I don't know anything! Papermaking? How to make it, gunpowder? How does that thing come with printing? Don't be ridiculous, I can't even make paper, you want me to do this? Compass? Um, what does that magnet look like before it's finished? Please watch: How does the uncle who was a loser before time travel and is still a loser after time travel play in a different world? Everyone is welcome to give your opinions. Anyway, I just look at it and don't listen.
