The armies of the heavens were only under the orders of invincibility!
As for the armies of the heavens battlefield, they only listened to the commands of the manor heads or the Great Qin King.
Before the upper echelons had completely fallen out, the military would not start a war.
It was also because of this that these tens of millions of soldiers still had their morale. They would not scatter like birds and beasts just because a few invincible soldiers had died.
