Cipher

i dont see a pattern between i-o and x-c.and how can i subtitute it on ubcwbruib?

i still dont get it.

is there any letter to be move to the right or to the left?

what does his means?<!-- i -> o --> <!-- x -> c -->?

change i to o and x to c in english alphabet?

can i decode it without any software?

why have to decode if the answer is already in front? i still don't get it.any other help?

yea.this makes me think outside the box.

too hard for a beginner ike me to use GIMP or adobe.i dont have any experience.T_T
