The 'weeds' the Fat Wizard mentioned refer to the pale green patterns similar to wild grass that cover the edges of the letter's paper, where the trihedral emblem of the First University can faintly be seen rotating.
Xiao Xiao reached out and wiped.
A segment of enlarged pattern appeared in mid-air, rotating slowly under the white light. A few lively sprites flew out from the tent, flitting up and down around the green pattern, dancing gracefully. Their joyful chirping even made Tuan Tuan open his eyes for a glance.
"Do you see it?" Xiao Xiao pointed to the pattern in mid-air with a brush, "Although these patterns look intricate, if you examine them closely, they're all variations of the same symbol..."
The tip of his brush lightly stroked and adjusted the patterns, occasionally slicing and rotating them, overlapping one identical design over another. In a short time, only one extremely simple pattern remained in mid-air.
