Why Does the Devil Need to Conquer the World?

After traveling through time and becoming a demon king, the system forced me to conquer the world within one year. I reorganized the "Dark Legion" into the "Demon Construction Corps" with a backhand. When the human coalition troops came to the city, what they saw was not the demon army, but the orc caravan holding the banner "Abyss Specialty, No Credit". Later, my KPI changed: [Mission: Double the GDP of the demon clan (completed)] [Mission: Become the largest supplier in the three worlds (ongoing)] [Task: Let the God of Light invest in my demon development zone (new)] System: Host, what about the promised conquest? Me: Conquering with goods and contracts, doesn't it count as conquest?
