After Sanders cleaned up the Transcendent remnants left from the research, Angel took out the Magic Pattern Engraving Pen, preparing to inscribe some magic runes in the laboratory.
The reason he came to the lower laboratory was exactly for this.
Regina would soon be conducting research on mushrooms in this lab. To prevent any unexpected situations, Angel decided to engrave some restriction and defense-type magic runes as countermeasures.
Because he already had the patterns in mind, Angel engraved them quickly. In less than half an hour, the magic runes were almost complete.
Once everything was done, Angel looked up and noticed that Sanders had not left. He was sitting on one side of the lab, resting one hand on his cheek while the other tapped lightly on the table with his fingertips, his eyes slightly squinted as if pondering something.
Perhaps it was Angel's unabashed gaze that was caught by Sanders' Spiritual Sense, as he slowly opened his eyes and looked at Angel.
