Kapitel 625: A Weird Monster

"…An unimaginable ghost…"

Compared to the previous notes, the two lines were written very heavily and hastily. The fear and panic between the lines could be easily felt.

"What monster could've possibly terrified a legendary sorcerer to such an extent? Also, why didn't he leave when he still had time? They should've already grasped the pattern of coordinate changes in this place…" Lucien showed no expression on his face, but he analyzed the anomalies in his heart.

Since the guy's notebook hadn't decayed at all after so many years without being looked after by anyone, and since the guy established a unique chamber inside the grey hall as his laboratory, Lucien was pretty sure that the writer was a legendary sorcerer. Those people wouldn't have been terrified even if they had run into a demigod. They might be devastated and defeated, but they shouldn't have been as scared as a little kid.

What kind of ghost was that?
