Stuck at the supercomputer

[空气新人]

I think the username is Lorelei and i should use the cipher on the magician poster.
I think the password is :
1st XXO 2nd: OXX 3rd: XOO
OOO OOO XOX
OXX OXX OOX
But the login always failed. Can someone tell me what's the problem?

I was stuck at the supercomputer for hours. You probably got the username and password right. I think the password changes from game to game, so it's hard to tell. Just make sure you are inputting the symbols in the correct order. The order is given by the signs in the gallery of the mirror world.

What you might be getting wrong is the relation between each vision and each year. Some of them can be ambiguous.

Mirror world gives the password - but keep in mind that

small hint: you should pay VERY close attention to the 3 patterns you're given

large hint: something weird happens as you move around the 3 pattern rooms

large hint 2: the patterns on the wall are lying to you

solution: there are 9 squares on the floor and on the wall - as you move across the squares on the floor, you'll also be visible on the 9 squares on the wall. Squares on the floor that show you in a red square on the wall are part of the real symbol in each room
