"I've studied the history of your world before it was invaded."
"You have the corresponding concept."
Lin Ye frowned, "You mean like a game? A competition?"
Geman nodded.
"Yes. To the Sin Gods, transforming our worlds into Professional civilizations and making us fight each other for resources is like playing a game."

"In the end, when there's nowhere to vent their anger, they'll vent it on the defeated dimensional civilization. They'll use the Dark Wave to invade and destroy the entire dimensional world.

Lin Ye roughly sorted out his thoughts.
