The First Clue

When you arrive in the year 2021, you need to retrieve a certain item. You see, the cause of all the problems in my time must've started in 2021, when the technology for A.I. machinery was invented.

From what I've heard, it all started with some scribbles. They were just meaningless doodles, at first, but A.I. robots were built based on that drawing. The scribbled note should be in a trash can somewhere. You must find it! Please, rifle through trash cans and bring me back that piece of paper!

You found it! Let me see!

I don't exactly know where the paper is... Search in every trash can you come across!

No, no, no. This isn't it. This isn't what I'm looking for. I could've sworn... I mean, I'm sure it was 2021 that A.I.'s were first designed and invented. Could it be that I'm mistaken?

This is important. Before things get worse, we must destroy that paper.

Keep searching in trash cans!
