As for why the veteran soldiers is discussing about the policy and cares about it, is because they have learned why in the past that the Yan dynasty seems so invincible to them
It is not because they are braver than the people of the Steppe and it is not because they are favoured by the heavens or any of those myths they shrouded themselves with to fool the tribes of the Steppe
Kultai also scoffed at this "how could those gods of Yan reached the land of the Skyfather and Earthmother. They would not allow it"
The reason why the Yan soldiers seems invincible is because of their armour, their weapons
Their arrows is more penetrating, their armour is more durable, more sturdy, their sword is sharper, and more cutting
So, they achieved the feat of killing more people.
And of course, to counter this, the Steppe people perfected the method of riding and archery, and master the art of cavalry archers.
