Chu Mo took the letter and opened it directly. It was short, but the handwriting was extremely neat and the strokes were strong; at a glance, one could tell that the person who wrote this letter had deep mastery in the art of magic.
"Young Master Chu, upon hearing of your sect's founding celebration today, a day of great joy, I send a modest gift to express my little bit of heartfelt sincerity, without claiming to be respectful. Wait for the day when you ascend to the Heavenly Realm, I shall find you and we will share wine and merriment." At the end of the letter, the signature didn't contain a full name, just a "Guo" character written with flamboyant flourish.
If one were to ignore everything that had just happened and simply look at this letter, one would really think it was just a common congratulatory letter. However, in the context of what had just occurred, everyone felt an eerie chill.
