"A kingdom that does not levy taxes? How could I not know about it?" Li Xuan said, pouring himself a cup of tea, "The Great Ancestor once inscribed the fifteen nations that are not to be invaded in the 'Imperial Jin Ancestral Instructions', and Fusou Nippon is one of them."
Emperor Tai of Jin originated from humble beginnings, thus he had an extra measure of sympathy for the common people's hardships.
He believed that 'extensive lands are no guarantee of lasting peace, and exhausting the populace is a source of chaos.' If Jin were to attack those barbaric nations, 'acquiring their lands would not support them, commanding their people would not work,' it would be a phantom reputation, self-destructively harming the Middle Earth."
This is actually very reasonable, Li Xuan knew that contemporary hegemonic nations had very little desire for land.
They had better methods to plunder wealth, rather than direct rule, which included the high costs of managing those lands.
