Lord of the Nation: My Discount Can Reverse the Cause and Effect

1. All the people traveled across the continent of ten thousand races, and everyone was a lord. Only I awakened the causal discount system. ​ 2.

The less money I spend, the more the world's rules favor me, the lower the discount, and the faster my enemies die.
