From MC's Perspective:
Time passed.
About two hours later, I appeared back inside the room. No one could sense my presence because of the system. Thanks to that, I'm going to kill him right now.
Suddenly, I found someone standing outside.
I slowly walked towards Charon Perry, who was in a deep sleep. I grabbed his shoulder and appeared inside the Gregor Mansion.
Swoosh!
Then I dropped him to the ground in the middle of the hall. At the same time, Charon Perry jolted awake.
"Where is this?"
"What's going on?"
He raised the questions, looking at the unfamiliar place. He recalled sleeping inside the hotel room, but he found himself in a different place right now.
On the other hand, my mouth curved into an arc. This moron doesn't know that I'm standing close to him.
"Gravity Domain."
I instantly cast the 4th stage of Gravity Domain. The powerful force appeared out of nowhere and mounted on him.
Pfff!
