Something worst than invasion

Invasion is simple, enemy comes in and the army figther back.
But one of the great general of china did not dude in the field.
In fact was killed by his prime minister.

He can beat 100,000 barbarian with 500 warrior.
But was betrayed by his own people.

See some bad is here too.
Seem too of trying to be a Utopia.
Ethopia spell almost the same too.

Christ the Saviour even consider his own people first.
And guess people are selling things to enemy thought people dun know.
 Even in the imperial edge, there is revolt.
Today demo system, seems much easier.

Just a conspiracy guess.
