The World Dominated by Parasites
"I'm…back at the System World." Compass Carburettor looked around, noticing that he was within the familiar forest. But, only the forest was familiar, the place wasn't.
He looked around, failing to spot any landmarks that he had seen before. But, he didn't have the freedom of time to think about that, hurriedly sprinting away from the place. That was the reason he had shot a bullet into the portal in the first place.
It was to arrive at the System World before the Dungeon Master arrived, thereby escaping to avoid angering the respective System. He didn't wish to make his existence as a System Slayer be known by other Systems.
That would only result in endless headaches. Moreover, the Dungeon Master was a powerful individual, capable of annihilating dozens of Transcendents on his own. So, the System supporting him should have been at a rather high level.
