The bold characters within the diary didn't make much sense on their own, but once he places them together, something interesting will be found. Leon flipped through the pages of the diary from beginning to end. The bold characters could be found throughout.
Leon pulled out a spare notebook and ink pen and prepared to record down the bold characters from start in sequence, however, his hand paused on the first character before he proceeded to store everything away in his Worldspace.
Entering the Whitespace, he summoned the Worldspace projection and scanned the diary before creating a copy in the archive.
Under his will, Leon used the power of the Whitespace to filter out all the unnecessary contents of the copied version of the diary and only kept the bold characters.
