Is There Anything Wrong with Using Dragon Breath for Production?

I, the last of the ancient dragon clan, was supposed to be guarding the gold and silver mountains and growing moldy in my lair, but I was bound to the "Thousand Realms Race Revitalization System" by an unscrupulous system. Now, my mission is to run a school, a factory, and a restaurant chain in another world, and lead a group of weak family members to achieve common prosperity. The former dragon-slaying hero came to his door not for justice, but to ask for unpaid wages. The demon army next door was approaching the city, and I handed over a "Letter of Intent for Cooperation on Magic Materials Export and Infrastructure Construction". While other dragons were showing off their treasures and princesses, I was holding a cup of coffee and worrying about the financial statements - this month's KPI was almost not completed. This is the story of how a dragon used capital and operations to peacefully (and abstractly) conquer the world.
