From MC's Perspective:
Inside the Gregor Mansion, I sat on the ground with disbelief on my face. It's hard to accept the fact that what I saw was a real thing.
A huge, monstrous arm comes out of nowhere, and it appears to be targeting the Forbidden Wizards. I only saw one of them crash and fall to the ground.
Then I saw four others fleeing as well.
Shortly afterwards,
The huge monstrous arm returns to the ground. I don't dare to go outside to check. Whatever the thing that monstrous arm belongs to.
It's extremely dangerous. It can even attack and injure a forbidden-level wizard. What kind of monstrous existence was it?
I have only heard about 10th Order Monsters. But this thing must be above it. Blood drained on my face. My palms were sweating. That was truly eye-opening.
It took me at least 20 minutes to calm down my heart and to think further.
