This yellowish piece of note in the diary looks pretty old. Most words on it are barely recognizable. All you can figure out from it are some confusing formulas:
"Green, blue, blue": time no longer flies!
"Green, red, yellow": what is this? A frog?
"Green, yellow, yellow": coin! Sparkling coin!
"Yellow, blue, blue": monsters' special features are removed!
"Green, red, green": the bright power that devils subject to!
"Red, red, blue": horrible dark smell that makes you tremble!
