Vermilion Bird Heavenly Country and Azure Dragon Heavenly Kingdom are neighboring states that have been in conflict for countless years. Each desires to annihilate the other and strengthen themselves.
Over these years of strife, there have been wins and losses on both sides.
However, neither side has yet suffered a crippling blow; at worst, only a few cities were lost or a couple of states ceded. No enemy has ever managed to reach the Imperial City.
The higher the level of a powerful nation, the more stable and secure it is.
As long as there is no serious internal strife and the rulers do not court disaster, it is very difficult for an enemy to destroy them.
Especially after a million years, every citizen of each Heavenly Country has developed a strong sense of national identity. Patriotism is the innate nature of every individual.
When foreign enemies invade, all citizens become soldiers.
Everyone will spontaneously resist the invasion of foreign troops.
